Coffee and tea are among the plants that are highest in caffeine. Their use as beverages makes caffeine the most consumed psychoactive agent in the world. Coffee is commonly used to increase alertness and work productivity. Synthetic caffeine is added to soft drinks, energy drinks, and products intended to reduce fatigue or promote weight loss.

The caffeine content varies with the type of drink: It is high in coffee, energy drinks, and caffeine tablets; intermediate in tea; and low in soft drinks. Coffee is the predominant source of the caffeine ingested by adults. The evidence for caffeine’s effects on people is ambiguous, and some risks and benefits deserve special attention because of the impact they may have on our health.
 

Characteristics of Caffeine

Caffeine is a methylxanthine that is completely absorbed 45 minutes after ingestion, peaking between 15 minutes and 2 hours. The half-life of caffeine varies according to age. In adults, it is 2.5-4.5 hours; in newborns, 80 hours; in children older than 6 months, it remains stable over time with respect to weight. Smoking accelerates caffeine metabolism by reducing the half-life by 50%. Oral contraceptives, however, double caffeine’s half-life. Caffeine metabolism is reduced during pregnancy (it is greater in the first trimester), with a half-life of more than 15 hours. Caffeine clearance can be slowed by several classes of drugs (eg, quinolones, cardiovascular drugs, bronchodilators, and antidepressants) that increase its half-life because they are metabolized by the same liver enzymes.

Caffeine passes the blood-brain barrier and, having an adenosine-like structure, inhibits adenosine’s effects by binding to adenosine receptors. In the brain, caffeine reduces fatigue, increases alertness, reduces reaction times, may reduce the risk for depression, and increases the effectiveness of nonsteroidal anti-inflammatory drugs in treating headaches and other types of pain.
 

Caffeine and Chronic Diseases

The evidence available on the relationship between caffeine and health has several methodological limitations. Observations of the acute effects of caffeine may not reflect long-term effects because tolerance to caffeine’s effects may develop over time. Smoking and unhealthy lifestyles are confounding factors in epidemiological studies of caffeine intake. In addition, the estimate of the amount and frequency of caffeine intake is often inaccurate because it is mainly based on self-assessment systems. Finally, prospective studies of caffeine consumption are mainly based on coffee and tea consumption, but it is unclear how much the observed outcomes can be translated to intake of other beverages such as energy drinks.

Considering the very high prevalence of arterial hypertension worldwide (31.1% of adults), many questions have been raised about the influence of coffee consumption on blood pressure (BP) and the risk for arterial hypertension. Administration of 200-300 mg caffeine is shown to induce a mean increase of 8.1 mm Hg systolic BP and 5.7 mm Hg diastolic BP. The increase is observed in the first hour after caffeine intake and lasts no longer than 3 hours.

Yet, the moderate and usual consumption of coffee does not increase, but may even reduce, the risk of developing high BP. In contrast, occasional coffee consumption can have hypertensive effects, and moderate and usual consumption in patients with high BP does not appear to increase the risk for uncontrolled BP and can reduce the risk for death from any cause. The inverse association between coffee consumption and hypertension risk was confirmed in a review and meta-analysis of cross-sectional and cohort studies.

With respect to lipid metabolism, cholesterol levels may increase after caffeine consumption because of cafestol. Concentrations of cafestol are high in unfiltered coffee, intermediate in espresso and moka pot coffee, and negligible in instant or filtered coffee. Studies on the impact of coffee on lipid levels have led to inconsistent results, however. Data have shown that people who drink more coffee have higher triglycerides, total cholesterol, and low-density lipoprotein cholesterol (LDL-C) levels. Other data have shown that caffeine promotes LDL receptor expression and clearance of LDL cholesterol.

Experimental and cohort studies have not shown an association between coffee consumption and atrial fibrillation (AF). In fact, evidence suggests that coffee consumption tends to reduce the risk for AF in a dose-response relationship. Similarly, coffee consumption is not associated with increased risk for cardiovascular events in the general population or among patients with a history of hypertension, diabetes, or cardiovascular disease.

The Coffee and Real-Time Atrial and Ventricular Ectopy study evaluated the acute effects of coffee consumption on cardiac ectopy using wearable sensors with continuous recording. It did not demonstrate any increase in daily premature atrial contractions with coffee consumption, compared with abstaining from caffeine. 

In patients with type 2 diabetes, a study performed in Japan showed that coffee consumption was associated with reduced all-cause mortality. The results suggested a dose-response relationship, and drinking coffee and green tea appeared to reduce mortality risk further. The results were not generalizable, however, because of the study population’s ethnic homogeneity.
 

Dose and Toxicity

Caffeine at high doses (> 400 mg daily) and in susceptible patients can induce anxiety, but the effects of caffeine on sleep and anxiety can differ from patient to patient. This variation reflects differences in caffeine metabolism rate and adenosine receptor gene variants.

High caffeine intake can stimulate diuresis, but without causing damaging effects on hydration when taking moderate doses of caffeine (≤ 400 mg daily) for long periods. Stopping caffeine suddenly, in a regular consumer, can lead to withdrawal symptoms such as headache, asthenia, decreased attention, depressed mood, and flu-like symptoms.

The toxic effects of caffeine occur with intake > 1.2 g. A dose of 10-14 g is considered fatal. Caffeine overdose is rare when considering traditional methods of intake (coffee and tea) because 70-100 cups of coffee should be sufficient for caffeine poisoning. Severe events can occur following the use of caffeine tablets or as energy drinks for the following reasons:

• The episodic consumption of caffeine does not allow for tolerance to develop.
• Young people are more vulnerable to the effects of caffeine.
• Caffeine has a synergistic effect in combination with other components in energy drinks.
• Taking caffeine in combination with alcohol or intense exertion causes serious, even fatal, outcomes.

Products Containing Caffeine

Evidence supports the relationship between high consumption (approximately 1 L) of energy drinks with a caffeine content of 320 mg and short-term cardiovascular adverse events, such as increased BP, QT-segment prolongation corrected for heart rate, and palpitations. These tests prompt the recommendation to avoid consuming these beverages in high quantities and in association with alcohol.

Weight loss products generally contain caffeine coupled with herbal extracts that are expected to improve fat metabolism, lipolysis, and oxidation. These products, because of their easy availability, presumed benefits, and high caffeine concentration, may be more susceptible to misuse because they can be taken in larger portions than recommended. The combination of multiple ingredients, concentrated amounts of caffeine, and excessive consumption increases the likelihood of adverse effects.

A new scanner can provide three-dimensional (3D) photoacoustic images of millimeter-scale veins and arteries in seconds.

The scanner, developed by researchers at University College London (UCL) in England, could help clinicians better visualize and track microvascular changes for a wide range of diseases, including cancer, rheumatoid arthritis (RA), and peripheral vascular disease (PVD).

In exploratory case studies, researchers demonstrated how the scanner visualized vessels with a corkscrew-like structure in patients with suspected PVD and mapped new blood vessel formation driven by inflammation in patients with RA.

The case studies “illustrate potential areas of application that warrant future, more comprehensive clinical studies,” the authors wrote. “Moreover, they demonstrate the feasibility of using the scanner on a real-world patient cohort where imaging is more challenging due to frailty, comorbidity, or pain that may limit their ability to tolerate prolonged scan times.”

The work was published online in Nature Biomedical Engineering.
 

Improving Photoacoustic Imaging

PAT works using the photoacoustic effect, a phenomenon where sound waves are generated when light is absorbed by a material. When pulsed light from a laser is directed at tissue, some of that light is absorbed and causes an increase in heat in the targeted area. This localized heat also increases pressure, which generates ultrasound waves that can be detected by specialized sensors.

While previous PAT scanners translated these sound waves to electric signals directly to generate imaging, UCL engineers developed a sensor in the early 2000s that can detect these ultrasound waves using light. The result was much clearer, 3D images.

“That was great, but the problem was it was very slow, and it would take 5 minutes to get an image,” explained Paul Beard, PhD, professor of biomedical photoacoustics at UCL and senior author of the study. “That’s fine if you’re imaging a dead mouse or an anesthetized mouse, but not so useful for human imaging,” he continued, where motion would blur the image.

In this new paper, Beard and colleagues outlined how they cut scanning times to an order of seconds (or fraction of a second) rather than minutes. While previous iterations could detect only acoustic waves from one point at a time, this new scanner can detect waves from multiple points simultaneously. The scanner can visualize veins and arteries up to 15 mm deep in human tissue and can also provide dynamic, 3D images of “time-varying tissue perfusion and other hemodynamic events,” the authors wrote.

With these types of scanners, there is always a trade-off between imaging quality and imaging speed, explained Srivalleesha Mallidi, PhD, an assistant professor of biomedical engineering at Tufts University in Medford, Massachusetts. She was not involved with the work.

“With the resolution that [the authors] are providing and the depth at which they are seeing the signals, it is one of the fastest systems,” she said.
 

Clinical Utility

Beard and colleagues also tested the scanner to visualize blood vessels in participants with RA, suspected PVD, and skin inflammation. The scanning images “illustrated how vascular abnormalities such as increased vessel tortuosity, which has previously been linked to PVD, and the neovascularization associated with inflammation can be visualized and quantified,” the authors wrote.

The next step, Beard noted, is testing whether these characteristics can be used as a marker for the progression of disease.

Nehal Mehta, MD, a cardiologist and professor of medicine at the George Washington University, Washington, DC, agreed that more longitudinal research is needed to understand how the abnormalities captured in these images can inform detection and diagnosis of various diseases.

“You don’t know whether these images look bad because of reverse causation — the disease is doing this — or true causation — that this is actually detecting the root cause of the disease,” he explained. “Until we have a bank of normal and abnormal scans, we don’t know what any of these things mean.”

Though still some time away from entering the clinic, Mehta likened the technology to the introduction of optical coherence tomography in the 1980s. Before being adapted for clinical use, researchers first needed to visualize differences between normal coronary vasculature and myocardial infarction.

“I think this is an amazingly strong first proof of concept,” Mehta said. “This technology is showing a true promise in the field imaging.”

The work was funded by grants from Cancer Research UK, the Engineering & Physical Sciences Research Council, Wellcome Trust, the European Research Council, and the National Institute for Health and Care Research University College London Hospitals Biomedical Research Centre. Beard and two coauthors are shareholders of DeepColor Imaging to which the intellectual property associated with the new scanner has been licensed, but the company was not involved in any of this research. Mallidi and Mehta had no relevant disclosures.

A first stroke in older adults is associated with substantial immediate and accelerated long-term cognitive decline, suggested a new study that underscores the need for continuous cognitive monitoring in this patient population.

Results from the study, which included 14 international cohorts of older adults, showed that stroke was associated with a significant acute decline in global cognition and a small, but significant, acceleration in the rate of cognitive decline over time.

Cognitive assessments in primary care are “crucial, especially since cognitive impairment is frequently missed or undiagnosed in hospitals,” lead author Jessica Lo, MSc, biostatistician and research associate with the Center for Healthy Brain Aging, University of New South Wales, Sydney, Australia, told this news organization.

She suggested clinicians incorporate long-term cognitive assessments into care plans, using more sensitive neuropsychological tests in primary care to detect early signs of cognitive impairment. “Early detection would enable timely interventions to improve outcomes,” Lo said.

She also noted that poststroke care typically includes physical rehabilitation but not cognitive rehabilitation, which many rehabilitation centers aren’t equipped to provide.

Cognitive impairment after stroke is common, but the trajectory of cognitive decline following a first stroke, relative to prestroke cognitive function, remains unclear.

The investigators leveraged data from 14 population-based cohort studies of 20,860 adults (mean age, 73 years; 59% women) to map the trajectory of cognitive function before and after a first stroke.

The primary outcome was global cognition, defined as the standardized average of four cognitive domains (language, memory, processing speed, and executive function).

During a mean follow-up of 7.5 years, 1041 (5%) adults (mean age, 79 years) experienced a first stroke, a mean of 4.5 years after study entry.

In adjusted analyses, stroke was associated with a significant acute decline of 0.25 SD in global cognition and a “small but significant” acceleration in the rate of decline of −0.038 SD per year, the authors reported.

Stroke was also associated with acute decline in all individual cognitive domains except for memory, with effect sizes ranging from −0.17 to −0.22 SD. Poststroke declines in Mini-Mental State Examination scores (−0.36 SD) were also noted.

In terms of cognitive trajectory, the rate of decline before stroke in survivors was similar to that seen in peers who didn’t have a stroke (−0.048 and −0.049 SD per year in global cognition, respectively).

The researchers did not identify any vascular risk factors moderating cognitive decline following a stroke, consistent with prior research. However, cognitive decline was significantly more rapid in individuals without stroke, regardless of any future stroke, who had a history of diabetes, hypertension, high cholesterol, cardiovascular disease, depression, smoking, or were APOE4 carriers.

“Targeting modifiable vascular risk factors at an early stage may reduce the risk of stroke but also subsequent risk of stroke-related cognitive decline and cognitive impairment,” the researchers noted.
 

A ‘Major Step’ in the Right Direction

As previously reported by this news organization, in 2023 the American Heart Association (AHA) issued a statement noting that screening for cognitive impairment should be part of multidisciplinary care for stroke survivors.

Commenting for this news organization, Mitchell Elkind, MD, MS, AHA chief clinical science officer, said these new data are consistent with current AHA guidelines and statements that “support screening for cognitive and functional decline in patients both acutely and over the long term after stroke.”

Elkind noted that the 2022 guideline for intracerebral hemorrhage states that cognitive screening should occur “across the continuum of inpatient care and at intervals in the outpatient setting” and provides recommendations for cognitive therapy.

“Our 2021 scientific statement on the primary care of patients after stroke also recommends screening for both depression and cognitive impairment over both the short- and long-term,” said Elkind, professor of neurology and epidemiology at Columbia University Irving Medical Center in New York City.

“These documents recognize the fact that function and cognition can continue to decline years after stroke and that patients’ rehabilitation and support needs may therefore change over time after stroke,” Elkind added.

The authors of an accompanying commentary called it a “major step” in the right direction for the future of long-term stroke outcome assessment.

“As we develop new devices, indications, and time windows for stroke treatment, it may perhaps be wise to ensure trials steer away from simpler outcomes to more complex, granular ones,” wrote Yasmin Sadigh, MSc, and Victor Volovici, MD, PhD, with Erasmus University Medical Center, Rotterdam, the Netherlands.

The study had no commercial funding. The authors and commentary writers and Elkind have declared no conflicts of interest.

A first stroke in older adults is associated with substantial immediate and accelerated long-term cognitive decline, suggested a new study that underscores the need for continuous cognitive monitoring in this patient population.

Results from the study, which included 14 international cohorts of older adults, showed that stroke was associated with a significant acute decline in global cognition and a small, but significant, acceleration in the rate of cognitive decline over time.

Cognitive assessments in primary care are “crucial, especially since cognitive impairment is frequently missed or undiagnosed in hospitals,” lead author Jessica Lo, MSc, biostatistician and research associate with the Center for Healthy Brain Aging, University of New South Wales, Sydney, Australia, told this news organization.

She suggested clinicians incorporate long-term cognitive assessments into care plans, using more sensitive neuropsychological tests in primary care to detect early signs of cognitive impairment. “Early detection would enable timely interventions to improve outcomes,” Lo said.

She also noted that poststroke care typically includes physical rehabilitation but not cognitive rehabilitation, which many rehabilitation centers aren’t equipped to provide.

The study was published online in JAMA Network Open.

TOPLINE:

Maternal serum folate levels during early to midpregnancy show a U-shaped association with congenital heart disease (CHD) risk in offspring. Both low and high folate levels are linked to an increased risk, with vitamin B12 deficiency and elevated homocysteine levels further exacerbating this risk.

METHODOLOGY:

• Researchers conducted a case-control study with 129 participants with CHD and 516 matched control participants from Guangdong Provincial People’s Hospital in China between 2015 and 2018.
• Maternal serum levels of folate, vitamin B12, and homocysteine were measured at around 16 weeks of gestation using a chemiluminescence microparticle immunoassay.
• CHD was confirmed using echocardiography, and the participants were matched by maternal age at a ratio of 1:4.
• Covariates included periconceptional folic acid supplementation, maternal education, occupation, parity, abortion history, pregnancy complications, and genetic polymorphisms related to folate metabolism.
• Conditional logistic regression was used to assess the associations, with adjustments for various covariates and sensitivity analyses excluding participants with missing genetic data.

TAKEAWAY:

• A U-shaped association was found between maternal serum folate levels and CHD risk in offspring, with both low and high levels linked to increased risk (P < .001).
• Low maternal folate levels were associated with an adjusted odds ratio (aOR) of 3.09 (95% CI, 1.88-5.08) for CHD risk, whereas high levels had an aOR of 1.81 (95% CI, 1.07-3.06).
• Using World Health Organization criteria, folate deficiency (< 5.9 ng/mL) had an aOR of 18.97 (95% CI, 3.87-93.11) and elevated levels (> 20 ng/mL) had an aOR of 5.71 (95% CI, 2.72-11.98) for CHD risk.
• Vitamin B12 deficiency and elevated homocysteine levels further increased the risk associated with both low and high maternal folate levels.

IN PRACTICE:

“Insufficient folate and vitamin B12 can lead to increased homocysteine levels, which is harmful to the cardiovascular system. Thus, homocysteine might act as a central mediator in the relationships between deficiencies in folate and vitamin B12 and the risk of CHD. Additionally, the role of folate extends beyond homocysteine mediation, contributing independently to placental implantation and vascular remodeling, irrespective of vitamin B12 and homocysteine levels,” the authors wrote.

SOURCE:

The study was led by Yanji Qu, PhD, and Jie Li, PhD, Global Health Research Center, Guangdong Provincial People’s Hospital, Guangdong Academy of Medical Sciences, Southern Medical University, Guangzhou, China. It was published online in JAMA Network Open.

LIMITATIONS:

The study’s limitations included the measurement of maternal serum folate levels at a single time point, which may not reflect preconception and early postconception periods. The study’s findings may not be generalizable to other populations as participants were recruited from a single cardiac referral center in Southern China. Additionally, the lack of dietary intake data limited the ability to account for related biases. The sample size, while relatively large for CHD research, may lack sufficient power for stratified analyses.

DISCLOSURES:

One coauthor reported receiving personal fees from Guangdong Cardiovascular Institute outside the submitted work. Additional disclosures are noted in the original article.

While Kellie Lease Stecher, MD, was working as an ob.gyn. in Minneapolis, Minnesota, a patient confided in her a sexual assault allegation about one of Stecher’s male colleagues. Stecher shared the allegation with her supervisor, who told Stecher not to file a report and chose not to address the issue with the patient. Stecher weighed how to do the right thing: Should she speak up? What were the ethical and legal implications of speaking up vs staying silent?

After seeking advice from her mentors, Stecher felt it was her moral and legal duty to report the allegation to the Minnesota Medical Board. Once she did, her supervisor chastised her repeatedly for reporting the allegation. Stecher soon found herself in a hostile work environment where she was regularly singled out and silenced by her supervisor and colleagues.

“I got to a point where I felt like I couldn’t say anything at any meetings without somehow being targeted after the meeting. There was an individual who was even allowed to fat-shame me with no consequences,” Stecher said. “[Being bullied at work is] a struggle because you have no voice, you have no opportunities, and there’s someone who is intentionally making your life uncomfortable.”

Stecher’s experience is not unusual. Mistreatment is a common issue among healthcare workers, ranging from rudeness to bullying and harassment and permeating every level and specialty of the medical profession. A 2019 research review estimated that 26.3% of healthcare workers had experienced bullying and found bullying in healthcare to be associated with mental health problems such as burnout and depression, physical health problems such as insomnia and headaches, and physicians taking more sick leave.

The Medscape Physician Workplace Culture Report 2024 found similarly bleak results:

• 38% said workplace culture is declining.
• 70% don’t see a big commitment from employers for positive culture.
• 48% said staff isn’t committed to positive culture.

Toxicity’s ripple effects contribute to several issues in healthcare, including staffing shortages, physician attrition, inadequate leadership, and even suicide rates.

The irony, of course, is that most physicians enter the field to care for people. As individuals go from medical school to residency and on with the rest of their careers, they often experience a rude awakening.
 

It’s Everywhere

Noticing the prevalence of workplace bullying in the medical field, endocrinologist Farah Khan, MD, at UW Medicine in Seattle, Washington, decided to conduct a survey on the issue.

Khan collected 122 responses from colleagues, friends, and acquaintances in the field. When asked if they had ever been bullied in medicine, 68% of respondents said yes. But here’s the fascinating part: She tried to pinpoint one particular area or source of toxicity in the progression of a physician’s career — and couldn’t because it existed at all levels.

More than one third of respondents said their worst bullying experiences occurred in residency, while 30% said mistreatment was worst in medical school, and 24% indicated their worst experience had occurred once they became an attending.

The litany of experiences included being belittled, excluded, yelled at, criticized, shamed, unfairly blamed, threatened, sexually harassed, subjected to bigotry and slurs, and humiliated.

“What surprised me the most was how widespread this problem is and the many different layers of healthcare it permeates through, from operating room staff to medical students to hospital HR to residents and attendings,” Khan said of her findings.
 

Who Cares for the Caregivers?

When hematologist Mikkael Sekeres, MD, was in medical school, he seriously considered a career as a surgeon. Following success in his surgical rotations, he scrubbed in with a cardiothoracic surgeon who was well known for both his status as a surgeon and his fiery temper. Sekeres witnessed the surgeon yelling at whoever was nearby: Medical students, fellows, residents, operating room nurses.

“At the end of that experience, any passing thoughts I had of going into cardiothoracic surgery were gone,” Sekeres said. “Some of the people I met in surgery were truly wonderful. Some were unhappy people.”

He has clear ideas why. Mental health struggles that are all too common among physicians can be caused or exacerbated by mistreatment and can also lead a physician to mistreat others.

“People bully when they themselves are hurting,” Sekeres said. “It begs the question, why are people hurting? What’s driving them to be bullies? I think part of the reason is that they’re working really hard and they’re tired, and nobody’s caring for them. It’s hard to care for others when you feel as if you’re hurting more than they are.”

Gail Gazelle, MD, experienced something like this. In her case, the pressure to please and to be a perfect professional and mother affected how she interacted with those around her. While working as a hospice medical director and an academician and clinician at Harvard Medical School, Boston, Massachusetts, she found herself feeling exhausted and burnt out but simultaneously guilty for not doing enough at work or at home.

Guess what happened? She became irritable, lashing out at her son and not putting her best foot forward with coworkers or patients.

After trying traditional therapy and self-help through books and podcasts, Gazelle found her solution in life coaching. “I realized just how harsh I was being on myself and found ways to reverse that pattern,” she said. “I learned ways of regulating myself emotionally that I definitely didn’t learn in my training.”

Today, Gazelle works as a life coach herself, guiding physicians through common challenges of the profession — particularly bullying, which she sees often. She remembers one client, an oncologist, who was being targeted by a nurse practitioner she was training. The nurse practitioner began talking back to the oncologist, as well as gossiping and bad-mouthing her to the nurses in the practice. The nurses then began excluding the oncologist from their cafeteria table at lunchtime, which felt blatant in such a small practice.

A core component of Gazelle’s coaching strategy was helping the client reclaim her self-esteem by focusing on her strengths. She instructed the client to write down what went well that day each night rather than lying in bed ruminating. Such self-care strategies can not only help bullied physicians but also prevent some of the challenges that might cause a physician to bully or lash out at another in the first place.

Such strategies, along with the recent influx of wellness programs available in healthcare facilities, can help physicians cope with the mental health impacts of bullying and the job in general. But even life coaches like Gazelle acknowledge that they are often band-aids on the system’s deeper wounds. Bullying in healthcare is not an individual issue; at its core, it’s an institutional one.
 

Negative Hierarchies in Healthcare

When Stecher’s contract expired, she was fired by the supervisor who had been bullying her. Stecher has since filed a lawsuit, claiming sexual discrimination, defamation, and wrongful termination.

The medical field has a long history of hierarchy, and while this rigidity has softened over time, negative hierarchical dynamics are often perpetuated by leaders. Phenomena like cronyism and cliques and behaviors like petty gossip, lunchroom exclusion (which in the worst cases can mimic high school dynamics), and targeting can be at play in the healthcare workplace.

The classic examples, Stecher said, can usually be spotted: “If you threaten the status quo or offer different ideas, you are seen as a threat. Cronyism ... strict hierarchies ... people who elevate individuals in their social arena into leadership positions. Physicians don’t get the leadership training that they really need; they are often just dumped into roles with no previous experience because they’re someone’s golfing buddy.”

The question is how to get workplace culture momentum moving in a positive direction. When Gazelle’s clients are hesitant to voice concerns, she emphasizes doing so can and should benefit leadership, as well as patients and the wider healthcare system.

“The win-win is that you have a healthy culture of respect and dignity and civility rather than the opposite,” she said. “The leader will actually have more staff retention, which everybody’s concerned about, given the shortage of healthcare workers.”

And that’s a key incentive that may not be discussed as much: Talent drain from toxicity. The Medscape Workplace Culture Report asked about culture as it applies to physicians looking to join up. Notably, 93% of doctors say culture is important when mulling a job offer, 70% said culture is equal to money, and 18% ranked it as more important than money, and 46% say a positive atmosphere is the top priority.

Ultimately, it comes down to who is willing to step in and stand up. Respondents to Khan’s survey counted anonymous reporting systems, more supportive administration teams, and zero-tolerance policies as potential remedies. Gazelle, Sekeres, and Stecher all emphasize the need for zero-tolerance policies for bullying and mistreatment.

“We can’t afford to have things going on like this that just destroy the fabric of the healthcare endeavor,” Gazelle said. “They come out sideways eventually. They come out in terms of poor patient care because there are greater errors. There’s a lack of respect for patients. There’s anger and irritability and so much spillover. We have to have zero-tolerance policies from the top down.”

Khan collected 122 responses from colleagues, friends, and acquaintances in the field. When asked if they had ever been bullied in medicine, 68% of respondents said yes. But here’s the fascinating part: She tried to pinpoint one particular area or source of toxicity in the progression of a physician’s career — and couldn’t because it existed at all levels.

More than one third of respondents said their worst bullying experiences occurred in residency, while 30% said mistreatment was worst in medical school, and 24% indicated their worst experience had occurred once they became an attending.

The litany of experiences included being belittled, excluded, yelled at, criticized, shamed, unfairly blamed, threatened, sexually harassed, subjected to bigotry and slurs, and humiliated.

“What surprised me the most was how widespread this problem is and the many different layers of healthcare it permeates through, from operating room staff to medical students to hospital HR to residents and attendings,” Khan said of her findings.
 

Who Cares for the Caregivers?

When hematologist Mikkael Sekeres, MD, was in medical school, he seriously considered a career as a surgeon. Following success in his surgical rotations, he scrubbed in with a cardiothoracic surgeon who was well known for both his status as a surgeon and his fiery temper. Sekeres witnessed the surgeon yelling at whoever was nearby: Medical students, fellows, residents, operating room nurses.

“At the end of that experience, any passing thoughts I had of going into cardiothoracic surgery were gone,” Sekeres said. “Some of the people I met in surgery were truly wonderful. Some were unhappy people.”

He has clear ideas why. Mental health struggles that are all too common among physicians can be caused or exacerbated by mistreatment and can also lead a physician to mistreat others.

“People bully when they themselves are hurting,” Sekeres said. “It begs the question, why are people hurting? What’s driving them to be bullies? I think part of the reason is that they’re working really hard and they’re tired, and nobody’s caring for them. It’s hard to care for others when you feel as if you’re hurting more than they are.”

Gail Gazelle, MD, experienced something like this. In her case, the pressure to please and to be a perfect professional and mother affected how she interacted with those around her. While working as a hospice medical director and an academician and clinician at Harvard Medical School, Boston, Massachusetts, she found herself feeling exhausted and burnt out but simultaneously guilty for not doing enough at work or at home.

Guess what happened? She became irritable, lashing out at her son and not putting her best foot forward with coworkers or patients.

After trying traditional therapy and self-help through books and podcasts, Gazelle found her solution in life coaching. “I realized just how harsh I was being on myself and found ways to reverse that pattern,” she said. “I learned ways of regulating myself emotionally that I definitely didn’t learn in my training.”

Today, Gazelle works as a life coach herself, guiding physicians through common challenges of the profession — particularly bullying, which she sees often. She remembers one client, an oncologist, who was being targeted by a nurse practitioner she was training. The nurse practitioner began talking back to the oncologist, as well as gossiping and bad-mouthing her to the nurses in the practice. The nurses then began excluding the oncologist from their cafeteria table at lunchtime, which felt blatant in such a small practice.

A core component of Gazelle’s coaching strategy was helping the client reclaim her self-esteem by focusing on her strengths. She instructed the client to write down what went well that day each night rather than lying in bed ruminating. Such self-care strategies can not only help bullied physicians but also prevent some of the challenges that might cause a physician to bully or lash out at another in the first place.

Such strategies, along with the recent influx of wellness programs available in healthcare facilities, can help physicians cope with the mental health impacts of bullying and the job in general. But even life coaches like Gazelle acknowledge that they are often band-aids on the system’s deeper wounds. Bullying in healthcare is not an individual issue; at its core, it’s an institutional one.
 

Negative Hierarchies in Healthcare

When Stecher’s contract expired, she was fired by the supervisor who had been bullying her. Stecher has since filed a lawsuit, claiming sexual discrimination, defamation, and wrongful termination.

The medical field has a long history of hierarchy, and while this rigidity has softened over time, negative hierarchical dynamics are often perpetuated by leaders. Phenomena like cronyism and cliques and behaviors like petty gossip, lunchroom exclusion (which in the worst cases can mimic high school dynamics), and targeting can be at play in the healthcare workplace.

The classic examples, Stecher said, can usually be spotted: “If you threaten the status quo or offer different ideas, you are seen as a threat. Cronyism ... strict hierarchies ... people who elevate individuals in their social arena into leadership positions. Physicians don’t get the leadership training that they really need; they are often just dumped into roles with no previous experience because they’re someone’s golfing buddy.”

The question is how to get workplace culture momentum moving in a positive direction. When Gazelle’s clients are hesitant to voice concerns, she emphasizes doing so can and should benefit leadership, as well as patients and the wider healthcare system.

“The win-win is that you have a healthy culture of respect and dignity and civility rather than the opposite,” she said. “The leader will actually have more staff retention, which everybody’s concerned about, given the shortage of healthcare workers.”

And that’s a key incentive that may not be discussed as much: Talent drain from toxicity. The Medscape Workplace Culture Report asked about culture as it applies to physicians looking to join up. Notably, 93% of doctors say culture is important when mulling a job offer, 70% said culture is equal to money, and 18% ranked it as more important than money, and 46% say a positive atmosphere is the top priority.

Ultimately, it comes down to who is willing to step in and stand up. Respondents to Khan’s survey counted anonymous reporting systems, more supportive administration teams, and zero-tolerance policies as potential remedies. Gazelle, Sekeres, and Stecher all emphasize the need for zero-tolerance policies for bullying and mistreatment.

“We can’t afford to have things going on like this that just destroy the fabric of the healthcare endeavor,” Gazelle said. “They come out sideways eventually. They come out in terms of poor patient care because there are greater errors. There’s a lack of respect for patients. There’s anger and irritability and so much spillover. We have to have zero-tolerance policies from the top down.”

While Kellie Lease Stecher, MD, was working as an ob.gyn. in Minneapolis, Minnesota, a patient confided in her a sexual assault allegation about one of Stecher’s male colleagues. Stecher shared the allegation with her supervisor, who told Stecher not to file a report and chose not to address the issue with the patient. Stecher weighed how to do the right thing: Should she speak up? What were the ethical and legal implications of speaking up vs staying silent?

After seeking advice from her mentors, Stecher felt it was her moral and legal duty to report the allegation to the Minnesota Medical Board. Once she did, her supervisor chastised her repeatedly for reporting the allegation. Stecher soon found herself in a hostile work environment where she was regularly singled out and silenced by her supervisor and colleagues.

“I got to a point where I felt like I couldn’t say anything at any meetings without somehow being targeted after the meeting. There was an individual who was even allowed to fat-shame me with no consequences,” Stecher said. “[Being bullied at work is] a struggle because you have no voice, you have no opportunities, and there’s someone who is intentionally making your life uncomfortable.”

Stecher’s experience is not unusual. Mistreatment is a common issue among healthcare workers, ranging from rudeness to bullying and harassment and permeating every level and specialty of the medical profession. A 2019 research review estimated that 26.3% of healthcare workers had experienced bullying and found bullying in healthcare to be associated with mental health problems such as burnout and depression, physical health problems such as insomnia and headaches, and physicians taking more sick leave.

The Medscape Physician Workplace Culture Report 2024 found similarly bleak results:

• 38% said workplace culture is declining.
• 70% don’t see a big commitment from employers for positive culture.
• 48% said staff isn’t committed to positive culture.

Toxicity’s ripple effects contribute to several issues in healthcare, including staffing shortages, physician attrition, inadequate leadership, and even suicide rates.

The irony, of course, is that most physicians enter the field to care for people. As individuals go from medical school to residency and on with the rest of their careers, they often experience a rude awakening.

A group of nurse practitioners (NPs) employed by the state of New York has sued the state, alleging that their employer has them doing the work of physicians but underpays them.

The New York State Civil Service Commission understates the job function of NPs, overstates their dependence on physicians, and inadequately pays them for their work, according to the complaint filed in the US District Court for the Northern District of New York.

The nurses claim the mistreatment is a consequence of the fact that “at least 80% of the state’s employed NPs are women.”

Michael H. Sussman, a Goshen, New York–based attorney for the nurses, said in an interview that New York NPs are increasingly being used essentially as doctors at state-run facilities, including prisons, yet the state has failed to adequately pay them.

The lawsuit comes after a decade-long attempt by NPs to attain equitable pay and the ability to advance their civil service careers, he said.

“New York state has not addressed the heart of the issue, which is that the classification of this position is much lower than other positions in the state which are not so female-dominated and which engage in very similar activities,” Sussman said.

The lawsuit claims that “the work of NPs is complex, equaling that of a medical specialist, psychiatrist, or clinical physician.”

A spokesman for the New York State Civil Service Commission declined comment, saying the department does not comment on pending litigation.
 

Novel Gender Discrimination Argument

Gender discrimination is a relatively new argument avenue in the larger equal work, equal pay debate, said Joanne Spetz, PhD, director of the Institute for Health Policy Studies at the University of California, San Francisco.

“This is the first time I’ve heard of [such] a case being really gender discrimination focused,” she said in an interview. “On one level, I think it’s groundbreaking as a legal approach, but it’s also limited because it’s focused on public, state employees.”

Spetz noted that New York has significantly expanded NPs’ scope of practice, enacting in 2022 legislation that granted NPs full practice authority. The law means NPs can evaluate, order, diagnose, manage treatments, and prescribe medications for patients without physician supervision.

“They are in a role where they are stepping back and saying, ‘Wait, why are [we] not receiving equal pay for equal work?’ ” Spetz said. “It’s a totally fair area for debate, especially because they are now authorized to do essentially equal work with a high degree of autonomy.”
 

Debate Over Pay Grade

The nurses’ complaint centers on the New York State Civil Service Commission’s classification for NPs, which hasn’t changed since 2006. NPs are classified at grade 24, and they have no possibility of internal advancement associated with their title, according to the legal complaint filed on September 17.

To comply with a state legislative directive, the commission in 2018 conducted a study of the NP classification but recommended against reclassification or implementing a career ladder. The study noted the subordinate role of NPs to physicians and the substantial difference between physician classification (entry at grade 34) and that of NPs, psychologists (grade 25), and pharmacists (grade 25).

The study concluded that higher classified positions have higher levels of educational attainment and licensure requirements and no supervision or collaboration requirements, according to the complaint.

At the time, groups such as the Nurse Practitioner Association and the Public Employees Federation (PEF) criticized the findings, but the commission stuck to its classification.

Following the NP Modernization Act that allowed NPs to practice independently, PEF sought an increase for NPs to grade 28 with a progression to grade 34 depending on experience.

“But to this date, despite altering the starting salaries of NPs, defendants have failed and refused to alter the compensation offered to the substantial majority of NPs, and each plaintiff remains cabined in a grade 24 with a discriminatorily low salary when compared with males in other job classifications doing highly similar functions,” the lawsuit contended.

Six plaintiffs are named in the lawsuit, all of whom are women and work for state agencies. Plaintiff Rachel Burns, for instance, works as a psychiatric mental health NP in West Seneca and is responsible for performing psychiatric evaluations for patients, diagnosis, prescribing medication, ordering labs, and determining risks. The evaluations are identical for a psychiatrist and require her to complete the same forms, according to the suit.

Another plaintiff, Amber Hawthorne Lashway, works at a correctional facility in Altona, where for many years she was the sole medical provider, according to the lawsuit. Lashway’s duties, which include diagnoses and treatment of inmates’ medical conditions, mirror those performed by clinical physicians, the suit stated.

The plaintiffs are requesting the court accept jurisdiction of the matter and certify the class they seek to represent. They are also demanding prospective pay equity and compensatory damages for the distress caused by “the long-standing discriminatory” treatment by the state.

The Civil Service Commission and state of New York have not yet responded to the complaint. Their responses are due on November 12.
 

Attorney: Case Impact Limited

Benjamin McMichael, PhD, JD, said the New York case is not surprising as more states across the country are granting nurses more practice autonomy. The current landscape tends to favor the nurses, he said, with about half of states now allowing NPs full practice authority.

“I think the [New York] NPs are correct that they are underpaid,” said McMichael, an associate professor of law and director of the Interdisciplinary Legal Studies Initiative at The University of Alabama in Tuscaloosa. “With that said, the nature of the case does not clearly lend itself to national change.”

The fact that the NP plaintiffs are employed by the state means they are using a specific set of laws to advance their cause, he said. Other NPs in other employment situations may not have access to the same laws.

Subclinical disease detected on imaging predicts death, report investigators who show that plaque burden found on 3D vascular ultrasound and coronary artery calcium on CT were better predictors of death than traditional risk factors.

The work not only highlights the importance of early detection, but it also has clinical implications, said Valentin Fuster, MD, president of the Mount Sinai Fuster Heart Hospital in New York. “It’s going to change things,” he said. “What I believe is going to happen is that we will begin to evaluate people with risk factors at age 30 using imaging. Today, we evaluate people at age 50 using clinical practice guidelines.”

Fuster’s team developed 3D vascular ultrasound to assess plaque burden and applied it in a prospective cohort study known as BioImage. The researchers assessed 6102 patients in Chicago, Illinois, and Fort Lauderdale, Florida, using 3D vascular ultrasound of the carotid artery and another well-established modality — coronary artery calcium, determined by CT.

Participants had no cardiovascular symptoms, yet their plaque burden and calcium scores at the beginning of the study were significantly associated with death during the 15 years of follow-up, even after taking risk factors and medication into account. The results are published in the Journal of the American College of Cardiology.

“Now, there is no question that subclinical disease on imaging predicts mortality,” said Fuster.

David J. Maron, MD, a preventive cardiologist at the Stanford University School of Medicine in California, calls the finding “very important.”

“The presence of atherosclerosis is powerful knowledge to guide the intensity of therapy and to motivate patients and clinicians to treat it,” said Maron, who is the co-author of an accompanying editorial and was not involved in the study.
 

Predicting Risk Early

The research also showed that the risk for death increases if the burden of plaque in the carotid artery increases over time. Both plaque burden shown on 3D vascular ultrasound and coronary artery calcium on CT were better predictors of death than traditional risk factors.

Maron says recent studies of younger populations, such as Progression of Early Subclinical Atherosclerosis (PESA) and Coronary Artery Risk Development in Young Adults (CARDIA), show that “risk factors at a young age have much more impact on arterial disease than when we measure risk factors at older age.” The CARDIA study showed signs of atherosclerosis in patients as young as in their twenties. This paradigm shift to early detection will now be possible thanks to technological advances like 3D vascular ultrasound.

Maron said he agrees with screening earlier in life. “The risk of having an event is related to the plaque burden and the number of years that a patient has been exposed to that burden. The earlier in life we can identify the burden to slow, arrest, or even reverse the plaque, the better.”

Maron points out that the study looked at an older population and did not include information on cause of death. While a study of younger people and data on cardiac causes of death would be useful, he says the study’s conclusions remain significant.
 

3D Vascular Ultrasound vs Coronary Artery Calcium

While both imaging methods in the study predicted death better than cardiovascular risk factors alone, each option has advantages.

For coronary artery calcium, “there’s a huge amount of literature demonstrating the association with cardiovascular events, there’s a standardized scoring system, there are widespread facilities for computed tomography, and there is not a lot of variability in the measurement — it’s not dependent on the operator,” said Maron.

But there is one drawback. The scoring system –— the Agatston score — can paradoxically go up following aggressive lowering of low-density lipoprotein cholesterol. “Once coronary calcium is present, it is challenging to interpret a repeat scan because we don’t know if the increase in score is due to progression or increasing density of the calcium, which is a sign of healing,” said Maron.

Vascular ultrasound avoids this problem and can also identify early noncalcified plaques and monitor their progression before they would appear on CT. Furthermore, the imaging does not add to lifetime radiation dose, as CT does, Fuster said.

3D ultrasound technology will soon be available in an inexpensive, automated, and easy-to-use format, he explains. Fuster envisions a scenario in which a nurse in a low-income country, using a cell phone app, will be able to assess atherosclerosis in a patient’s femoral artery. “In less than 1 hour, we can predict disease much more rigorously than with risk factors alone,” he said. “I think this is very exciting.”
 

Progression Increases Risk

Finding any atherosclerosis means an increased risk for death, but a greater burden or amount of atherosclerosis increases that risk, said Fuster. Progression of atherosclerosis increases risk even further. 

The study looked at changes in atherosclerosis burden on vascular ultrasound in a subset of 732 patients a median of 8.9 years after their first test. Those with progression had a higher risk for death than those with regression or no atherosclerosis. “Progression is much more significant in predicting mortality than atherosclerosis findings alone,” Fuster said.

Maron said this finding points to “two great values from noninvasive imaging of atherosclerosis.” Not only does imaging detect atherosclerosis, but it can also characterize the burden and any calcification. Further, it allows doctors to monitor the response to interventions such as lifestyle changes and medical therapy. “Serial imaging of plaque burden will really enhance the management of atherosclerosis,” said Maron. “If we discover that someone is progressing rapidly, we can intensify therapy.”

He says imaging results also provide needed motivation for both clinicians and patients to take action that would prevent the deaths that result from atherosclerosis.

Subclinical disease detected on imaging predicts death, report investigators who show that plaque burden found on 3D vascular ultrasound and coronary artery calcium on CT were better predictors of death than traditional risk factors.

The work not only highlights the importance of early detection, but it also has clinical implications, said Valentin Fuster, MD, president of the Mount Sinai Fuster Heart Hospital in New York. “It’s going to change things,” he said. “What I believe is going to happen is that we will begin to evaluate people with risk factors at age 30 using imaging. Today, we evaluate people at age 50 using clinical practice guidelines.”

Fuster’s team developed 3D vascular ultrasound to assess plaque burden and applied it in a prospective cohort study known as BioImage. The researchers assessed 6102 patients in Chicago, Illinois, and Fort Lauderdale, Florida, using 3D vascular ultrasound of the carotid artery and another well-established modality — coronary artery calcium, determined by CT.

Participants had no cardiovascular symptoms, yet their plaque burden and calcium scores at the beginning of the study were significantly associated with death during the 15 years of follow-up, even after taking risk factors and medication into account. The results are published in the Journal of the American College of Cardiology.

“Now, there is no question that subclinical disease on imaging predicts mortality,” said Fuster.

David J. Maron, MD, a preventive cardiologist at the Stanford University School of Medicine in California, calls the finding “very important.”

“The presence of atherosclerosis is powerful knowledge to guide the intensity of therapy and to motivate patients and clinicians to treat it,” said Maron, who is the co-author of an accompanying editorial and was not involved in the study.
 

Predicting Risk Early

The research also showed that the risk for death increases if the burden of plaque in the carotid artery increases over time. Both plaque burden shown on 3D vascular ultrasound and coronary artery calcium on CT were better predictors of death than traditional risk factors.

Maron says recent studies of younger populations, such as Progression of Early Subclinical Atherosclerosis (PESA) and Coronary Artery Risk Development in Young Adults (CARDIA), show that “risk factors at a young age have much more impact on arterial disease than when we measure risk factors at older age.” The CARDIA study showed signs of atherosclerosis in patients as young as in their twenties.

Over the past few years, many states have attempted to address the ongoing shortage of healthcare workers by introducing new bills to increase the scope of practice for nurse practitioners (NPs) and physician assistants (PAs). The goal of each bill was to improve access to care, particularly for patients who may live in areas where it’s difficult to find a doctor.

In response, the American Medical Association (AMA) launched a targeted campaign to fight “scope creep.” Their goal was to gain the momentum necessary to block proposed legislation to modify or expand the practice authority of nonphysicians, including PAs. A spokesperson for the organization told this news organization that the AMA “greatly values and respects the contributions of PAs as important members of the healthcare team” but emphasized that they do not have the same “skill set or breadth of experience of physicians.”

As such, the AMA argued that expanded practice authority would not only dismantle physician-led care teams but also ultimately lead to higher costs and lower-quality patient care.

The AMA has since launched a large-scale advocacy effort to fight practice expansion legislation — and has a specific page on its website to highlight those efforts. In addition, they have authored model legislation, talking points for AMA members, and a widely read article in AMA News to help them in what they call a “fight for physicians.”

These resources have also been disseminated to the greater healthcare stakeholder community.

Marilyn Suri, PA-C, chief operating officer and senior executive for Advanced Practice Professional Affairs at Vincenzo Novara MDPA and Associates, a critical care pulmonary medicine practice in Miami, Florida, said she found the AMA’s campaign to be “very misleading.”

“PAs are created in the image of physicians to help manage the physician shortage. We are trained very rigorously — to diagnose illness, develop treatment plans, and prescribe medications,” she said. “We’re not trying to expand our scope. We are trying to eliminate or lessen barriers that prevent patients from getting access to care.”

Suri is not alone. Last summer, the American Academy of Physician Associates (AAPA) requested a meeting with the AMA to find ways for the two organizations to collaborate to improve care delivery — as well as find common ground to address issues regarding patient access to care. When the AMA did not respond, the AAPA sent a second letter in September 2024, reiterating their request for a meeting.

That correspondence also included a letter, signed by more than 8000 PAs from across the country, calling for an end to what the AAPA refers to as “damaging rhetoric,” as well as data from a recent survey of PAs regarding the fallout of AMA’s scope creep messaging.

Those survey results highlighted that the vast majority of PAs surveyed feel that the AMA is doing more than just attacking proposed legislation: They believe the association is negatively influencing patients’ understanding of PA qualifications, ultimately affecting their ability to provide care.

“The campaign is unintentionally harming patients by suggesting we are doing more than what we are trained to do,” said Elisa Hock, PA-C, a behavioral health PA in Texas. “And when you work in a place with limited resources, medically speaking — including limited access to providers — this kind of campaign is really detrimental to helping patients.”

Lisa M. Gables, CEO of the AAPA, said the organization is “deeply disappointed” in the AMA’s lack of response to their letters thus far — but remains committed to working with the organization to bring forward new solutions to address healthcare’s most pressing challenges.

“AAPA remains committed to pushing for modernization of practice laws to ensure all providers can practice medicine to the fullest extent of their training, education, and experience,” she said. “That is what patients deserve and want.”

Hock agreed. She told this news organization that the public is not always aware of what PAs can offer in terms of patient care. That said, she believes newer generations of physicians understand the value of PAs and the many skills they bring to the table.

“I’ve been doing this for 17 years, and it’s been an uphill battle, at times, to educate the public about what PAs can and can’t do,” she explained. “To throw more mud in the mix that will confuse patients more about what we do doesn’t help. Healthcare works best with a team-based approach. And that team has been and always will be led by the physician. We are aware of our role and our limitations. But we also know what we can offer patients, especially in areas like El Paso, where there is a real shortage of providers.”

With a growing aging population — and the physician shortage expected to increase in the coming decade — Suri hopes that the AMA will accept AAPA’s invitation to meet — because no one wins with this kind of healthcare infighting. In fact, she said patients will suffer because of it. She hopes that future discussions and collaborations can show providers and patients what team-based healthcare can offer.

“I think it’s important for those in healthcare to be aware that none of us work alone. Even physicians collaborate with other subspecialties, as well as nurses and other healthcare professionals,” said Suri. “[Physicians and PAs] need to take a collaborative approach. We need each other. PAs are not physicians. But, just like physicians, we are considered safe and trusted care providers because of our education and training. And we can increase access to care for patients tomorrow if we start working together.”

BOSTON — With the remarkable advances made in therapy over the past decade, many patients with cystic fibrosis (CF) can expect to survive into their 50s and even well beyond. But as patients with CF live longer, they are increasingly likely to develop complications such as cardiovascular diseases (CVDs) that beset many older adults. And as evidence from a new study suggests, there is an increasing need for cardiovascular screening and specialized cardiac care for these patients.

Among more than 83,000 patients with CF hospitalized for any reason from 2016 through 2021, less than 1% of patients had a cardiac cause listed, but in unadjusted analyses, these patients had a more than twofold risk for in-hospital death than those with CF hospitalized for other causes, reported Adnan Bhat, MD, assistant professor of hospital medicine at the University of Florida, Gainesville.

Although the excess mortality was no longer statistically significant in analyses adjusted for potential confounding factors, the data highlight a trend that requires further exploration, he said during an oral abstract session at the annual meeting of the American College of Chest Physicians (CHEST).

“There’s a trend for people with cystic fibrosis admitted for cardiac causes to have a higher in-hospital mortality and increased rate of discharge to nursing facilities, especially for patients admitted for heart failure. The clinical implication is that there is an increased need to start screening for cardiovascular risk factors,” he said.
 

National Database Sample

Bhat and colleagues conducted a retrospective study using the National Inpatient Sample database to identify all hospitalizations among patients with CF in the United States from 2016 through 2021.

They included all hospitalizations with a principal diagnosis code for atrial fibrillation, heart failure, or myocardial infarction.

Of 83,250 total hospitalizations during the study period, 415 (0.5%) were for primary cardiac causes. These included 170 hospitalizations for atrial fibrillation, 95 for heart failure, and 150 for myocardial infarction.

Patients hospitalized for cardiac causes had a higher mean age (59.5 vs 34.5 years) and more comorbidities than patients hospitalized for other causes. These comorbidities included hyperlipidemia, chronic kidney disease, obesity, and a family history of coronary artery disease.

In all, 5% of patients hospitalized for cardiac cause died in hospital, compared with 2% of patients hospitalized for other reasons (P = .044).

However, in logistic regression analyses adjusting for age, sex, and race, this difference was no longer significant.

Similarly, an unadjusted analysis showed that patients with cardiac disease were twice as likely to be discharged to a nursing facility (8% vs 4%, respectively), but this difference too disappeared in adjusted analyses.

The risk for in-hospital mortality appeared to be highest among those patients with a primary diagnosis of heart failure, who had an 11% rate of in-hospital death, compared with 2% among patients with CF hospitalized for other causes.

The total number of deaths was too small, however, to allow for regression analysis, Bhat said.

Nonetheless, taken together, the data indicate a trend toward increased mortality from cardiovascular causes among older patients with CF, as well as the need for further research into the cardiovascular health of these patients, Bhat concluded.
 

Better Nutrition, Higher Risk

In an interview, Yuqing A. Gao, MD, from the Santa Monica Pulmonary Sleep Clinic in California, who was not involved in the study, commented that with the advent of elexacaftor/tezacaftor/ivacaftor modulator therapy, patients with CF tend to have increases in body mass index and improved nutritional intake and absorption, which in turn could increase hyperlipidemia and other factors that might in turn contribute to increased CVD risk.

“It’s really an interesting area of research, and there’s hope that this will bring more focus on how to better screen [for CVD risk] because that’s something that’s very much not known at this time,” she said.

Gao was co-moderator for the session where Bhat presented the data. Bhat did not report a study funding source. Bhat and Gao reported no relevant financial relationships.

Bhat and colleagues conducted a retrospective study using the National Inpatient Sample database to identify all hospitalizations among patients with CF in the United States from 2016 through 2021.

They included all hospitalizations with a principal diagnosis code for atrial fibrillation, heart failure, or myocardial infarction.

Of 83,250 total hospitalizations during the study period, 415 (0.5%) were for primary cardiac causes. These included 170 hospitalizations for atrial fibrillation, 95 for heart failure, and 150 for myocardial infarction.

Patients hospitalized for cardiac causes had a higher mean age (59.5 vs 34.5 years) and more comorbidities than patients hospitalized for other causes. These comorbidities included hyperlipidemia, chronic kidney disease, obesity, and a family history of coronary artery disease.

In all, 5% of patients hospitalized for cardiac cause died in hospital, compared with 2% of patients hospitalized for other reasons (P = .044).

However, in logistic regression analyses adjusting for age, sex, and race, this difference was no longer significant.

Similarly, an unadjusted analysis showed that patients with cardiac disease were twice as likely to be discharged to a nursing facility (8% vs 4%, respectively), but this difference too disappeared in adjusted analyses.

The risk for in-hospital mortality appeared to be highest among those patients with a primary diagnosis of heart failure, who had an 11% rate of in-hospital death, compared with 2% among patients with CF hospitalized for other causes.

The total number of deaths was too small, however, to allow for regression analysis, Bhat said.

Nonetheless, taken together, the data indicate a trend toward increased mortality from cardiovascular causes among older patients with CF, as well as the need for further research into the cardiovascular health of these patients, Bhat concluded.
 

Better Nutrition, Higher Risk

In an interview, Yuqing A. Gao, MD, from the Santa Monica Pulmonary Sleep Clinic in California, who was not involved in the study, commented that with the advent of elexacaftor/tezacaftor/ivacaftor modulator therapy, patients with CF tend to have increases in body mass index and improved nutritional intake and absorption, which in turn could increase hyperlipidemia and other factors that might in turn contribute to increased CVD risk.

“It’s really an interesting area of research, and there’s hope that this will bring more focus on how to better screen [for CVD risk] because that’s something that’s very much not known at this time,” she said.

Gao was co-moderator for the session where Bhat presented the data. Bhat did not report a study funding source. Bhat and Gao reported no relevant financial relationships.

BOSTON — With the remarkable advances made in therapy over the past decade, many patients with cystic fibrosis (CF) can expect to survive into their 50s and even well beyond. But as patients with CF live longer, they are increasingly likely to develop complications such as cardiovascular diseases (CVDs) that beset many older adults. And as evidence from a new study suggests, there is an increasing need for cardiovascular screening and specialized cardiac care for these patients.

Among more than 83,000 patients with CF hospitalized for any reason from 2016 through 2021, less than 1% of patients had a cardiac cause listed, but in unadjusted analyses, these patients had a more than twofold risk for in-hospital death than those with CF hospitalized for other causes, reported Adnan Bhat, MD, assistant professor of hospital medicine at the University of Florida, Gainesville.

Although the excess mortality was no longer statistically significant in analyses adjusted for potential confounding factors, the data highlight a trend that requires further exploration, he said during an oral abstract session at the annual meeting of the American College of Chest Physicians (CHEST).

“There’s a trend for people with cystic fibrosis admitted for cardiac causes to have a higher in-hospital mortality and increased rate of discharge to nursing facilities, especially for patients admitted for heart failure. The clinical implication is that there is an increased need to start screening for cardiovascular risk factors,” he said.

BOSTON — The sooner that patients with acute pulmonary embolism (PE) get treated with mechanical thrombectomy, the greater the likelihood that they will have favorable short- and long-term outcomes, regardless of their degree of initial risk, a study of registry data showed.

Among nearly 800 patients with acute PE whose data are recorded in the FlowTriever All-Comer Registry for Patient Safety and Hemodynamics (FLASH), a prospective multicenter registry of individuals treated with mechanical thrombectomy using the FlowTriever system (Inari Medical), shorter time from admission to mechanical thrombectomy was associated with significantly greater reductions in intraprocedural mean and systolic pulmonary artery pressures (PAP), greater reductions in the right ventricular/left ventricular (RV/LV) ratio, and longer 6-minute walk times at 6 months, reported Krunal H. Patel, MD, a pulmonary and critical care fellow at the Lewis Katz School of Medicine at Temple University Hospital in Philadelphia.

“Mechanical thrombectomy in the FLASH registry showed a mortality benefit. I think as time progresses and mechanical thrombectomy becomes more popular, we’re just going to need to figure out what is the ideal time for intervention,” he said during an oral abstract session at the American College of Chest Physicians (CHEST) 2024 Annual Meeting.

“There’s mortality benefit in any case whether the patient is high-risk or intermediate-high. This is a thought-provoking retrospective analysis that says that early intervention is probably better than doing it late, but regardless, the FLASH registry trial showed that early thrombectomy or thrombectomy in general shows positive mortality benefit,” Patel said in an interview.

He likened the challenge for pulmonary and critical care specialists to that of interventional cardiologists, who have determined that the ideal window for starting percutaneous coronary interventions is within 90 minutes of the patient’s arrival at the facility.

“I think we have to get our ‘door-to-balloon’ time for PE care,” he said.
 

Study Details

Patel and colleague Parth M. Rali, MD, FCCP, associate professor of thoracic medicine at Temple, conducted a retrospective review of data on 787 US patients in the FLASH registry for whom time to mechanical thrombectomy data were available. They stratified the patients into short and long time to mechanical thrombectomy groups, with “short” defined as ≤ 12 hours of presentation and “long” as > 12 hours.

They found that the median time to thrombectomy was 19.68 hours. In all, 242 patients (31%) were treated within the short window, and the remaining 545 patients (69%) were treated after at least 12 hours had passed.

Comparing clinical characteristics between the groups, the investigators noted that significantly more patients in the short time group vs long time group were categorized as high-risk (11.2% vs 6.2%; P = .0026). This difference is likely due to the need for greater urgency among high-risk patients, Patel said.

Patients in the short time group also had significantly higher baseline RV/LV ratios and lactate levels, but baseline dyspnea scores and pre-procedure median and systolic PAP were similar between the groups.

The mean time to thrombectomy was 6.08 hours in the short time group vs 34.04 hours in the long time group. Their respective median times were 6.01 and 24.73 hours.

The procedural time was similar between the groups, at 45 and 42 minutes, respectively.

The location of the treated thrombus was central only in 35.1% and 26.5% patients in the short and long time groups, respectively. Lobar-only thrombi were treated in 7.9% and 14.3%, respectively, and both central and lobar thrombi were treated in 57.0% and 59.2%, respectively.

Both 48-hour and 30-day all-cause mortality rates were similar between the groups (0.4%/0.2% and 0.5%/1.0%).

Patients in the short time group had slightly but significantly longer post-procedure hospital and intensive care unit stays, but 30-day readmission rates — whether for PE- or non-PE–related causes — were similar.

Where the differences between the groups really showed, however, were PAP reductions over baseline, with decline in median pressures of −8.7 mm Hg in the short group vs −7.2 mm Hg in the long group (P = .0008), and drops in systolic PAP of −14.4 vs −12.1 mm Hg, respectively (P = .0011).

In addition, reductions in RV/LV ratios from baseline were also significantly greater among patients whose thrombectomies had been expedited at the 48-hour, 30-day, and 6-month follow-up periods.

At 6 months, patients who had received mechanical thrombectomy within 12 hours also had significantly longer 6-minute walk distances (442.2 vs 390.5 m; P = .0032).
 

Low Thrombolysis Rate

Following his presentation, session co-moderator Galina Glazman-Kuczaj, MD, from the Division of Pulmonary and Critical Care Medicine at Albany Med Health System, Albany, New York, asked Patel what percentage of patients, if any, had received thrombolytic therapy before the thrombectomy procedure.

He noted that only 1% or 2% patients in the FLASH registry received thrombolysis.

In an interview, Glazman-Kuczaj said that “it was reassuring for [Patel] to report that it was only a small population of patients who got thrombolysis beforehand in either group because you would expect that maybe people in the group that took longer to have a thrombectomy got some thrombolysis beforehand and that perhaps they were more stable, but it seems like thrombectomy was the first-line treatment in both groups.”
