Concerns that low LDL-C alters cognitive function challenged in novel analysis

PCSK9 inhibitors, which are among the most effective therapies for reducing LDL cholesterol (LDL-C), are associated with a neutral effect on cognitive function, according to a genetics-based Mendelian randomization study intended to sort out through the complexity of confounders.

The same study linked HMG-Co A reductase inhibitors (statins) with the potential for modest adverse neurocognitive effects, although these are likely to be outweighed by cardiovascular benefits, according to a collaborating team of investigators from the U.S. National Institutes of Health and the University of Oxford (England).

For clinicians and patients who continue to harbor concerns that cognitive function is threatened by very low LDL-C, this novel approach to evaluating risk is “reassuring,” according to the authors.

Early in clinical testing of PCSK9 inhibitors, a potential signal for adverse effects on cognitive function was reported but unconfirmed. This signal raised concern that extremely low levels of LDL-C, such as < 25 mg/dL, achieved with PCSK9 inhibitors might pose a risk to neurocognitive function.

Of several factors that provided a basis for concern, the PCSK9 enzyme is known to participate in brain development, according to the authors of this newly published study.
 

Mendelian randomization addresses complex issue

The objective of this Mendelian randomization analysis was to evaluate the relationship of PCSK9 inhibitors and statins on long-term neurocognitive function. Used previously to address other clinical issues, a drug-effect Mendelian randomization analysis evaluates genetic variants to determine whether there is a causal relationship between a risk, which in this case was lipid-lowering drugs, to a specific outcome, which was cognitive performance.

By looking directly at genetic variants that simulate the pharmacological inhibition of drug gene targets, the bias of confounders of clinical effects, such as baseline cognitive function, are avoided, according to the authors.

The message from this drug-effect Mendelian analysis was simple, according to the senior author of the study, Falk W. Lohoff, MD, chief of the section on clinical genomics and experimental therapeutics, National Institute of Alcohol Abuse and Alcoholism.

“Based on our data, we do not see a significant cognitive risk profile with PCSK9 inhibition associated with low LDL-C,” Dr. Lohoff said in an interview. He cautioned that “future long-term clinical studies are needed to confirm the absence of this effect,” but he and his coauthors noted that these data concur with the clinical studies.

From genome-wide association studies, single-nucleotide polymorphisms in PCSK9 and HMG-Co A reductase were extracted from a sample of more than 700,000 individuals of predominantly European ancestry. In the analysis, the investigators evaluated whether inhibition of PCSK9 or HMG-Co A reductase had an effect on seven clinical outcomes that relate to neurocognitive function, including memory, verbal intelligence, and reaction time, as well as biomarkers of cognitive function, such as cortical surface area.

The genetic effect of PCSK9 inhibition was “null for every cognitive-related outcome evaluated,” the investigators reported. The genetic effect of HMG-Co A reductase inhibition had a statistically significant but modest effect on cognitive performance (P = .03) and cortical surface area (P = .03). While the impact of HMG-Co A reductase inhibition on reaction time was stronger on a statistical basis (P = .0002), the investigators reported that it translated into a decrease of only 0.067 milliseconds per 38.7 mg/dL. They characterized this as a “small impact” unlikely to outweigh clinical benefits.

In an editorial that accompanied publication of this study, Brian A. Ference, MD, MPhil, provided context for the suitability of a Mendelian randomization analysis to address this or other questions regarding the impact of lipid-lowering therapies on clinical outcomes, and he ultimately concurred with the major conclusions

Dr. Brian A. Ference

Ultimately, this analysis is consistent with other evidence that PCSK9 inhibition does not pose a risk of impaired cognitive function, he wrote. For statins, he concluded that this study “does not provide compelling evidence” to challenge their current clinical use.


 

 

 

Data do not support low LDL-C as cognitive risk factor

Moreover, this study – as well as other evidence – argues strongly against very low levels of LDL-C, regardless of how they are achieved, as a risk factor for diminished cognitive function, Dr. Ference, director of research in the division of translational therapeutics, University of Cambridge (England), said in an interview.

“There is no evidence from Mendelian randomization studies that lifelong exposure to lower LDL-C increases the risk of cognitive impairment,” he said. “This is true when evaluating lifelong exposure to lower LDL-C due to genetic variants in a wide variety of different genes or the genes that encode the target PCKS9 inhibitors, statins, or other lipid-lowering therapies.”

In other words, this study “adds to the accumulating evidence” that LDL-C lowering by itself does not contribute to an adverse impact on cognitive function despite persistent concern. This should not be surprising. Dr. Ference emphasized that there has never been strong evidence for an association.

“As I point out in the editorial, there is no biologically plausible mechanism by which reducing peripheral LDL-C should impact neurological function in any way, because the therapies do not cross the blood brain barrier, and because the nervous system produces its own cholesterol to maintain the integrity of membranes in nervous system cells,” he explained.

Dr. Lohoff reports no potential conflicts of interest. Dr. Ference has financial relationships with numerous pharmaceutical companies including those that make lipid-lowering therapies.

Social isolation, loneliness tied to death, MI, stroke: AHA

Article Type
Changed
Mon, 08/08/2022 - 10:51

People who are socially isolated or lonely have an increased risk for myocardial infarction, stroke, and death, independent of other factors, the American Heart Association concludes in a new scientific statement.

More than 4 decades of research have “clearly demonstrated that social isolation and loneliness are both associated with adverse health outcomes,” writing group chair Crystal Wiley Cené, MD, University of California San Diego Health, said in a news release.

Dr. Crystal Wiley Cené

“Given the prevalence of social disconnectedness across the United States, the public health impact is quite significant,” Dr. Cené added.

The writing group says more research is needed to develop, implement, and test interventions to improve cardiovascular (CV) and brain health in people who are socially isolated or lonely.

The scientific statement was published online in the Journal of the American Heart Association.
 

Common and potentially deadly

Social isolation is defined as having infrequent in-person contact with people and loneliness is when a person feels he or she is alone or has less connection with others than desired.

It’s estimated that one-quarter of community-dwelling Americans 65 years and older are socially isolated, with even more experiencing loneliness.

The problem is not limited to older adults, however. Research suggests that younger adults also experience social isolation and loneliness, which might be attributed to more social media use and less frequent in-person activities.

Dr. Cené and colleagues reviewed observational and intervention research on social isolation published through July 2021 to examine the impact of social isolation and loneliness on CV and brain health.

The evidence is most consistent for a direct association between social isolation, loneliness, and death from coronary heart disease (CHD) and stroke, they reported.

For example, one meta-analysis of 19 studies showed that social isolation and loneliness increase the risk for CHD by 29%; most of these studies focused on acute MI and/or CHD death as the measure of CHD.

A meta-analysis of eight longitudinal observational studies showed social isolation and loneliness were associated with a 32% increased risk for stroke, after adjustment for age, sex, and socioeconomic status.

The literature also suggests social isolation and loneliness are associated with worse prognoses in adults with existing CHD or history of stroke.

One systematic review showed that socially isolated people with CHD had a two- to threefold increase in illness and death over 6 years, independent of cardiac risk factors.

Other research suggests that socially isolated adults with three or fewer social contacts per month have a 40% increased risk for recurrent stroke or MI.

There are fewer and less robust data on the association between social isolation and loneliness with heart failure (HF), dementia, and cognitive impairment, the writing group noted.

It’s also unclear whether actually being isolated (social isolation) or feeling isolated (loneliness) matters most for cardiovascular and brain health, because only a few studies have examined both in the same sample, they pointed out.

However, a study published in Neurology in June showed that older adults who reported feeling socially isolated had worse cognitive function at baseline than did those who did not report social isolation, and were 26% more likely to have dementia at follow-up, as reported by this news organization.
 

 

 

Urgent need for interventions

“There is an urgent need to develop, implement, and evaluate programs and strategies to reduce the negative effects of social isolation and loneliness on cardiovascular and brain health, particularly for at-risk populations,” Dr. Cené said in the news release. 

She encourages clinicians to ask patients about their social life and whether they are satisfied with their level of interactions with friends and family, and to be prepared to refer patients who are socially isolated or lonely, especially those with a history of CHD or stroke, to community resources to help them connect with others.

Fitness programs and recreational activities at senior centers, as well as interventions that address negative thoughts of self-worth and other negative thinking, have shown promise in reducing isolation and loneliness, the writing group said.

This scientific statement was prepared by the volunteer writing group on behalf of the AHA Social Determinants of Health Committee of the Council on Epidemiology and Prevention and the Council on Quality of Care and Outcomes Research; the Prevention Science Committee of the Council on Epidemiology and Prevention and the Council on Quality of Care and Outcomes Research; the Prevention Science Committee of the Council on Epidemiology and Prevention and the Council on Cardiovascular and Stroke Nursing; the Council on Arteriosclerosis, Thrombosis, and Vascular Biology; and the Stroke Council.

This research had no commercial funding. Members of the writing group have disclosed no relevant conflicts of interest.

Hot weather risk for nonfatal MI hinted for antiplatelets, beta-blockers

Article Type
Changed
Mon, 08/08/2022 - 08:02

Patients who take beta-blockers or antiplatelet agents are lowering their risk for cardiovascular events, but the protection may fall short for those who spend time outdoors on hot summer days, hints a limited analysis published as a letter in Nature Cardiovascular Research.

Patients taking either a beta-blocker or antiplatelet, or both medications together, appeared at elevated risk for nonfatal acute MI specifically on days when the weather turned hot, suggests the registry cohort study that covered 14 years of clinical and meteorologic data.

“The take-away message is not that patients should stop using these two medications, by no means. We’re raising cautions for patients taking them, to watch out for themselves during high-heat days,” lead author Kai Chen, PhD, Yale University, New Haven, Conn., said in an interview.

“We’re not giving the message that these drugs have harmful effects” because the nature of the links between the medications and MI in the study, with its potential for confounding, remain unknown, said Dr. Chen, from the department of environmental health sciences and Yale Center on Climate Change and Health.

For example, patients who take beta-blockers or antiplatelets tend to be sicker than patients not on the drugs, which could make heat-related MI more likely, and the drugs wrongly appear to be culprits, he observed. The analysis contained signals that could support either scenario.

The study is based on cases of nonfatal MI in Augsburg, Germany, that are part of the MONICA-KORA MI registry. The odds of a heat-related nonfatal MI, it suggests, were increased 63% among patients taking antiplatelets and by 65% among those on beta-blockers, compared with those not on these drugs. The odds went up by 75% among those on both drug classes, but the risks weren’t raised in patients not taking them.
 

Rising heat-related MI

Chen said analysis was inspired by a 2019 report – also based on MONICA-KORA, from many of the same authors and using similar methods to track events by daily air temperature – that showed a rising trend for heat-related MI and declining rate for MI related to cold weather from 1987 to 2014. A next step, he figured, would be to determine whether the MI risk trends were associated with any cardiovascular medications.

The current study’s signal of risk related to antiplatelets and beta-blockers did not emerge for ACE inhibitors, calcium-channel blockers, or diuretics. Statins showed a link to increased nonfatal MI risk, but solely among participants aged younger than 60 years, who were also far less likely to have pre-existing coronary heart disease (CHD). He and his colleagues chose not to highlight that finding, Dr. Chen said, because the age subgroup analysis was grossly underpowered.

The overall analysis involved 2,494 cases of nonfatal MI that occurred during the warmer months – May to September – from 2001 to 2014. It was limited to nonfatal cases – those with at least a month of survival after hospital admission – because of insufficient data on medication use associated with fatal MIs, the report states.

Nonfatal MIs were defined as heat-related if they struck on days reaching the 95th percentile for temperature across the 14 years, in this case 24.2 °C (about 75.6 °F), relative to the average temperature of lowest nonfatal MI risk across the cohort, 7.5 °C (about 45.5 °F).

Patients served as both cases and their own controls, in that air temperature exposures on the day of their MI (case day) were compared with the remaining same days of the week in the same calendar month (control days). That approach, the report stated, “automatically controls for long-term time trends, seasonality, day of the week, and time-invariant confounders (for example, pre-existing cardiovascular disease).”

The odds ratio for heat-related MI for patients on antiplatelets was 1.63 (95% confidence interval, 1.07-2.46), and for antiplatelet nonusers was 0.94 (95% CI, 0.68-1.29). The difference between the two ratios was significant (P = .04).

The corresponding OR for patients taking beta-blockers was 1.65 (95% CI, 1.11-2.45), and for nonusers of beta-blockers was 0.90 (95% CI, 0.64-1.26). Again, the OR difference was significant (P = .02).

The ORs for users of both medication classes and nonusers of either med class, respectively, were 1.75 (95% CI, 1.12-2.73) and 0.84 (95% CI, 0.59-1.19). The latter OR was significantly lower than former (P = .01).

In a sign that antiplatelet and beta-blocker use might have been just a marker for sicker patients who were more vulnerable to heat-related MI, Chen said, the nonfatal MI risk was significantly elevated (OR, 2.17; 95% CI, 1.40-3.38) among patients with pre-existing CHD, but not among those free of pre-existing CHD (OR, 0.88; 95% CI, 0.65-1.20); the odds difference was P < .01.

That signal of confounding by indication is somewhat countered, the report states, by variations in nonfatal MI risk by age group. The increased chances of an event seen overall in relation to beta-blockers and antiplatelets were more pronounced among the 39% of patients aged 25-59 years (P < .01). That’s in spite that group’s lower CHD prevalence. The risk elevation solely among the older patients was attenuated and rendered nonsignificant, even with their greater CHD burden, the report noted.

The report speculates on a potential mechanism by which beta-blockers, at least, might conceivably raise the risk for heat-related MI. “Beta-receptor blockers inhibit skin vasodilation, resulting in reduced heat dissipation through convection and, at the same time, could intensify the blood-pressure-lowering effect of other antihypertensive drugs, which then could lead to syncope.”

Beta-blockers, Dr. Chen said, “can mechanistically make people more vulnerable to heat. That’s one potential explanation. Or it could be that these people taking the medications are just sicker. Whatever the reasons, the phenomenon we observed is that these patients taking these two medications are at higher risk during high-temperature days.”

Dr. Chen and the other authors declare no competing interests.

Patients who take beta-blockers or antiplatelet agents are lowering their risk for cardiovascular events, but the protection may fall short for those who spend time outdoors on hot summer days, hints a limited analysis published as a letter in Nature Cardiovascular Research.

Patients taking either a beta-blocker or antiplatelet, or both medications together, appeared at elevated risk for nonfatal acute MI specifically on days when the weather turned hot, suggests the registry cohort study that covered 14 years of clinical and meteorologic data.

“The take-away message is not that patients should stop using these two medications, by no means. We’re raising cautions for patients taking them, to watch out for themselves during high-heat days,” lead author Kai Chen, PhD, Yale University, New Haven, Conn., said in an interview.

“We’re not giving the message that these drugs have harmful effects” because the nature of the links between the medications and MI in the study, with its potential for confounding, remain unknown, said Dr. Chen, from the department of environmental health sciences and Yale Center on Climate Change and Health.

For example, patients who take beta-blockers or antiplatelets tend to be sicker than patients not on the drugs, which could make heat-related MI more likely, and the drugs wrongly appear to be culprits, he observed. The analysis contained signals that could support either scenario.

The study is based on cases of nonfatal MI in Augsburg, Germany, that are part of the MONICA-KORA MI registry. The odds of a heat-related nonfatal MI, it suggests, were increased 63% among patients taking antiplatelets and by 65% among those on beta-blockers, compared with those not on these drugs. The odds went up by 75% among those on both drug classes, but the risks weren’t raised in patients not taking them.
 

Rising heat-related MI

Chen said analysis was inspired by a 2019 report – also based on MONICA-KORA, from many of the same authors and using similar methods to track events by daily air temperature – that showed a rising trend for heat-related MI and declining rate for MI related to cold weather from 1987 to 2014. A next step, he figured, would be to determine whether the MI risk trends were associated with any cardiovascular medications.

The current study’s signal of risk related to antiplatelets and beta-blockers did not emerge for ACE inhibitors, calcium-channel blockers, or diuretics. Statins showed a link to increased nonfatal MI risk, but solely among participants aged younger than 60 years, who were also far less likely to have pre-existing coronary heart disease (CHD). He and his colleagues chose not to highlight that finding, Dr. Chen said, because the age subgroup analysis was grossly underpowered.

The overall analysis involved 2,494 cases of nonfatal MI that occurred during the warmer months – May to September – from 2001 to 2014. It was limited to nonfatal cases – those with at least a month of survival after hospital admission – because of insufficient data on medication use associated with fatal MIs, the report states.

Nonfatal MIs were defined as heat-related if they struck on days reaching the 95th percentile for temperature across the 14 years, in this case 24.2 °C (about 75.6 °F), relative to the average temperature of lowest nonfatal MI risk across the cohort, 7.5 °C (about 45.5 °F).

Patients served as both cases and their own controls, in that air temperature exposures on the day of their MI (case day) were compared with the remaining same days of the week in the same calendar month (control days). That approach, the report stated, “automatically controls for long-term time trends, seasonality, day of the week, and time-invariant confounders (for example, pre-existing cardiovascular disease).”

The odds ratio for heat-related MI for patients on antiplatelets was 1.63 (95% confidence interval, 1.07-2.46), and for antiplatelet nonusers was 0.94 (95% CI, 0.68-1.29). The difference between the two ratios was significant (P = .04).

The corresponding OR for patients taking beta-blockers was 1.65 (95% CI, 1.11-2.45), and for nonusers of beta-blockers was 0.90 (95% CI, 0.64-1.26). Again, the OR difference was significant (P = .02).

The ORs for users of both medication classes and nonusers of either med class, respectively, were 1.75 (95% CI, 1.12-2.73) and 0.84 (95% CI, 0.59-1.19). The latter OR was significantly lower than former (P = .01).

‘Staggering’ CVD rise projected in U.S., especially in minorities

Article Type

Thu, 12/15/2022 - 14:28

A new analysis projects steep increases by 2060 in the prevalence of cardiovascular (CV) risk factors and disease that will disproportionately affect non-White populations who have limited access to health care.

The study by Reza Mohebi, MD, Massachusetts General Hospital and Harvard Medical School, both in Boston, and colleagues was published in the Journal of the American College of Cardiology.

“Even though several assumptions underlie these projections, the importance of this work cannot be overestimated,” Andreas P. Kalogeropoulos, MD, MPH, PhD, and Javed Butler, MD, MPH, MBA, wrote in an accompanying editorial. “The absolute numbers are staggering.”

From 2025 to 2060, the number of people with any one of four CV risk factors – type 2 diabetes, hypertension, dyslipidemia, and obesity – is projected to increase by 15.4 million, to 34.7 million.

And the number of people with of any one of four CV disease types – ischemic heart disease, heart failure, MI, and stroke – is projected to increase by 3.2 million, to 6.8 million.

Although the model predicts that the prevalence of CV risk factors will gradually decrease among White Americans, the highest prevalence of CV risk factors will be among the White population because of its overall size.

Conversely, the projected prevalence of CV risk factors is expected to increase in Black, Hispanic, Asian, and other race/ethnicity populations.

In parallel, the prevalence of CV disease is projected to decrease in the White population and increase among all other race/ethnicities, particularly in the Black and Hispanic populations.

“Our results project a worrisome increase with a particularly ominous increase in risk factors and disease in our most vulnerable patients, including Blacks and Hispanics,” senior author James L. Januzzi Jr., MD, summarized in a video issued by the society.

“The steep rise in CV risk factors and disease reflects the generally higher prevalence in populations projected to increase in the United States, owing to immigration and growth, including Black or Hispanic individuals,” Dr. Januzzi, also from Massachusetts General and Harvard, said in an interview.

“The disproportionate size of the risk is expected in a sense, as minority populations are disproportionately disadvantaged with respect to their health care,” he said. “But whether it is expected or not, the increase in projected prevalence is, nonetheless, concerning and a call to action.”

This study identifies “areas of opportunity for change in the U.S. health care system,” he continued. “Business as usual will result in us encountering a huge number of individuals with CV risk factors and diseases.”

The results from the current analysis assume there will be no modification in health care policies or changes in access to care for at-risk populations, Dr. Mohebi and colleagues noted.

To “stem the rising tide of CV disease in at-risk individuals,” would require strategies such as “emphasis on education regarding CV risk factors, improving access to quality healthcare, and facilitating lower-cost access to effective therapies for treatment of CV risk factors,” according to the researchers.

“Such advances need to be applied in a more equitable way throughout the United States, however,” they cautioned.
 

 

 

Census plus NHANES data

The researchers used 2020 U.S. census data and projected growth and 2013-2018 U.S. National Health and Nutrition Survey data to estimate the number of people with CV risk factors and CV disease from 2025 to 2060.

The estimates are based on a growing population and a fixed frequency.



The projected changes in CV risk factors and disease over time were similar in men and women.

The researchers acknowledge that study limitations include the assumption that the prevalence patterns for CV risk factors and disease will be stable.

“To the extent the frequency of risk factors and disease are not likely to remain static, that assumption may reduce the accuracy of the projections,” Dr. Januzzi said. “However, we would point out that the goals of our analysis were to set general trends, and not to seek to project exact figures.”

Also, they did not take into account the effect of COVID-19. CV diseases were also based on self-report and CV risk factors could have been underestimated in minority populations that do not access health care.

Changing demographic landscape

It is “striking” that the numbers of non-White individuals with CV risk factors is projected to surpass the number of White individuals over time, and the number of non-White individuals with CV disease will be almost as many as White individuals by the year 2060, the editorialists noted.

“From a policy perspective, this means that unless appropriate, targeted action is taken, disparities in the burden of cardiovascular disease are only going to be exacerbated over time,” wrote Dr. Kalogeropoulos, from Stony Brook (N.Y.) University, and Dr. Butler, from Baylor College of Medicine, Dallas.

“On the positive side,” they continued, “the absolute increase in the percent prevalence of cardiovascular risk factors and conditions is projected to lie within a manageable range,” assuming that specific prevention policies are implemented.



“This is an opportunity for professional societies, including the cardiovascular care community, to re-evaluate priorities and strategies, for both training and practice, to best match the growing demands of a changing demographic landscape in the United States,” Dr. Kalogeropoulos and Dr. Butler concluded.

Is Lp(a) a marker for aortic calcium onset?

Article Type
Changed
Fri, 08/05/2022 - 15:34

Lipoprotein(a) has long been thought to be a potential marker of aortic valve disease, and the population-based Rotterdam Study in the Netherlands has reported that Lp(a) has a strong association with new-onset aortic valve calcium (AVC), but not necessarily with progression of aortic valve disease.

Reporting in the European Heart Journal, the study authors analyzed data on 922 participants in the Rotterdam Study whose Lp(a) was measured along with a computed tomography scan upon enrollment, followed by CT scan 14 years later. At baseline, 702 participants didn’t have AVC, but the follow-up scan identified new-onset AVC in 415 (59.1%).

Dr. Daniel Bos

The investigators found an association between Lp(a) concentration and baseline AVC, with an odds ratio of 1.43 for each 50 mg/dL higher Lp(a) (95% confidence interval, 1.15-1.79), as well as new-onset AVC, with an OR of 1.30 for each 50 mg/dL increase in Lp(a) (95% CI, 1.02-1.65). However, the study found no association between rising Lp(a) levels and AVC progression; it found only an association between baseline AVC score and progression (P < .001).
 

‘Trigger’ for calcification but not progression

“This suggests that Lp(a) is an important trigger in the initiation of aortic valve calcification, but once the valve is calcified, disease progression may be primarily driven by other factors such as the baseline calcium burden of the valve and likely other unknown factors,” senior study author Daniel Bos, MD, PhD, said in e-mailed comments.

Dr. Bos and coauthors claim this is the first study to show that even minor AVC progresses independently of Lp(a).

“There are previous studies that showed a possible relationship between Lp(a) [and] progression of aortic valve calcium,” he said. “Our study suggests that the most meaningful benefit of Lp(a) lowering may actually be prior to the onset of aortic valve calcification.”



While no treatments have been approved for lowering Lp(a), the study findings could be meaningful if trials, including the ongoing phase 3 Lp(a) HORIZON trial of the investigational antisense agent pelacarsen (NCT04023552), show promising results, Dr. Bos said. Citing Lp(a) HORIZON, he said, “If the study shows Lp(a) lowering leads to a reduction in incident cardiovascular disease, similar strategies may be applied to prevent, rather than slow down, progression of aortic valve calcification.”

Dr. Bos called the Rotterdam Study results “an important first pointer into that direction.” He added, “We will need randomized trials to provide a definitive answer to the question whether Lp(a) lowering may prevent aortic valve calcium.”

Focus on AVC is study ‘weakness’

The study findings raise a key question for clinical trials of investigative Lp(a)-lowering therapies as well as how to use those therapies to treat aortic valve disease, said Christie Ballantyne, MD, chief of cardiology at Baylor College of Medicine in Houston.

Dr. Christie M. Ballantyne

The findings could be “problematic” for these clinical trials, he said. “This study is just looking at calcium progression,” Dr. Ballantyne noted. “What we want to know about clinically is the progression to aortic stenosis, and then in particular to progression from mild disease to moderate or severe disease, because once you get into more severe disease, one has to do an intervention with either surgery or TAVR [transcatheter aortic valve replacement].”

He considered the study’s focus on AVC rather than aortic valve function a weakness and noted that only 14 study participants had TAVR. “We’re going to need much bigger numbers to look into this question of progression, including progression to severe diseases,” he said.

However, the Rotterdam Study showed the importance of CT in evaluating AVC, which can easily be done in other trials to further explore the association between Lp(a) and AVC, Dr. Ballantyne said.

Dr. Bos has no relevant disclosures. Study coauthors disclosed relationships with Amgen, Sanofi, Reservlogix, Athera, Experio, Novartis and Ionis Pharmaceuticals. Dr. Ballantyne disclosed relationships with Amgen and Novartis.

Ezetimibe plus statin: Attractive bypass to high-dose monotherapy

Article Type
Changed
Tue, 08/02/2022 - 11:01

More patients with established atherosclerotic cardiovascular disease (ASCVD) achieved a low-density lipoprotein (LDL) cholesterol of less than 70 mg/dL, and fewer discontinued treatment with ezetimibe plus a moderate-dose statin, than did those on high-intensity statin monotherapy, a noninferiority trial shows.

While it’s now established that drug combinations can achieve better efficacy with lower risks than high-dose monotherapy, the study is the first to show the benefits of the strategy for ASCVD in a randomized trial with long-term follow-up.

The primary endpoint – 3-year composite of cardiovascular death, major cardiovascular events, or nonfatal stroke – occurred in about 9% of patients in each group, showing non-inferiority.

Furthermore, the authors suggest that ezetimibe combination therapy be considered earlier in the treatment of those at high risk of adverse events, rather than doubling the statin dose.

The study was published online  in The Lancet.
 

Less intolerance, less discontinuations

The open-label study, dubbed RACING, randomized 3,780 patients with ASCVD to receive moderate-intensity rosuvastatin 10 mg plus ezetimibe 10 mg or high-intensity 20 mg rosuvastatin monotherapy. Participants’ average age was 64 and 75% were men.

The primary endpoint occurred in 9.1% of patients in the combination therapy group and 9.9% in the high-intensity monotherapy group. The absolute between-group difference was −0.78% (90% confidence interval [CI], −2.39 to 0.83), well below the 2% noninferiority margin.

In the combination therapy group, LDL cholesterol concentrations of less than 70 mg/dL were achieved in 73% of patients at 1 year, 75% at 2 years, and 72% at 3 years. By contrast, in the monotherapy group, the lower concentrations were seen in 55% at 1 year, 60% at 2 years, and 58% at 3 years.

Further, a post hoc analysis showed LDL concentrations of less than 55 mg/dL at 1, 2, and 3 years in 42%, 45%, and 42% of patients in the combination therapy group versus 25%, 29%, and 25% of those in the high-intensity statin monotherapy group.

Eighty-eight patients (4.8%) on combination therapy discontinued medication or received a dose reduction, versus 150 patients (8.2%) on monotherapy.

Rates of myonecrosis were similar in the combination therapy and high-intensity statin groups (11 vs. 13), whereas myalgia was more common with high-intensity statins (29 vs. 17). The open-label design could have led to bias in reporting of patient symptoms, the authors noted. All clinical events, however, were adjudicated by an independent committee masked to treatment assignment.

There might be “some level of difference” when extending the findings to other populations because the trial involved only Koreans, coauthor Myeong-Ki Hong, MD, Yonsei University, Seoul, South Korea, acknowledged in response to a query from this news organization. He thinks the findings can be applied broadly nonetheless, and his team is currently investigating whether certain patients might benefit more than others from the combination.
 

Various options for patients

“The field of hypertension changed [its] guidelines almost 20 years ago to consider the initial use of combination therapy in hard-to-treat patients,” Christie Mitchell Ballantyne, MD, Baylor College of Medicine, Houston, said in an interview. He coauthored an accompanying editorial with Baylor colleague Layla A. Abushamat, MD.

“We now have enough evidence of the efficacy and safety of combination therapy to consider early initiation of this approach in patients with challenging lipid disorders who are at increased risk of ASCVD events,” affirmed Dr. Ballantyne.

“This study reinforces important principles in the management and secondary prevention of cardiovascular disease, namely that LDL reduction and associated risk reduction can be achieved in various ways,” said Daniel Muñoz, MD, MPA, executive medical director of the Vanderbilt Heart & Vascular Institute, Vanderbilt University Medical Center, Nashville, Tenn.

However, he noted, “The high-intensity statin dose used as a comparator in this study was rosuvastatin 20 mg. In clinical practice, we often target maximally aggressive reduction of LDL via higher doses – that is, rosuvastatin 40 mg or atorvastatin 80 mg.”

The bottom line, said Dr. Muñoz, who was not involved in the study: “There are different ways to achieve LDL-lowering and associated risk reduction in patients with CVD. For patients who warrant but might not tolerate high-intensity statin therapy, this study supports the use of a moderate-intensity statin in combination with ezetimibe.”

The study was funded by Hanmi Pharmaceutical, Seoul, South Korea. One study coauthor received an institutional research grant from the company. No other authors reported relevant financial relationships, nor did Dr. Ballantyne, Dr. Abushamat, or Dr. Muñoz.

For patients with peripheral artery disease, pain can be gain

Article Type
Changed
Mon, 08/01/2022 - 10:55

For people with peripheral artery disease (PAD), even short walks can be exercises in excruciation.

But a new study published  in the Journal of the American Heart Association has found that patients who can push through the pain appear to reap significant benefits in ambulation, balance, and leg strength, which have been linked to increased longevity.

“You have to push yourself and get those uncomfortable symptoms, or else you probably won’t get gains,” said Mary McDermott, MD, professor of medicine at Northwestern University, Chicago, and the senior author of the study.

M. Alexander Otto/MDedge News
Dr. Mary McDermott

Walking for exercise is critical for people with lower-extremity PAD, Dr. McDermott said, but leg pain dissuades many people with the condition from doing so. She said her group hopes that showing the payoff of the “no pain, no gain” approach gives people with PAD the resolve to walk regularly, even when it’s hard.

The new study, a post hoc analysis of the LITE (Low-Intensity Exercise Intervention in PAD) trial, found that low-intensity exercise did not improve the symptoms of PAD but high-intensity exercise did.

Dr. McDermott and her colleagues compared 109 people with PAD who walked fast enough to cause discomfort versus 101 people who walked at a comfortable pace and 54 people who did not exercise at all. The average age was 69 years, 48% of participants were women, and 61% were Black.

Everyone in the exercise groups walked at home, with visits to a medical center early in the study to get exercise tips and then phone support from exercise coaches throughout the remainder of the study. Researchers encouraged those in the discomfort group to walk fast enough to cause significant pain in their legs, for up to 10 minutes or as long as they could. They then rested before walking again, ideally up to five times per day for 5 days per week.

At 6 months, people in the discomfort group were walking 0.056 m/sec faster than those in the comfort group during a 4-meter walking test (95% confidence interval [CI], 0.19-0.094 m/sec; P < .01), a gap that had grown by 12 months to 0.084 m/sec (95% CI, 0.049-0.120 m/sec; P <.01), according to the researchers. A statistically significant gap also emerged between the discomfort and nonexercising group at 6 months, but it eventually closed.

“It’s a question that people have asked for some time: Is it necessary to get that ischemic pain when you walk?” Dr. McDermott said. “This is the first well-powered clinical trial to provide a definitive answer on that, and the answer is that you do need that discomfort. It wasn’t even close.” Indeed, Dr. McDermott said, it’s possible that walking merely to the point of comfort and never pushing beyond it may harm people with PAD.

At the 6-month mark, the researchers found no statistical difference between the discomfort and comfort groups on a cumulative scale of usual walking speed, ability to rise from a chair, and ability to maintain balance in several positions. By 12 months, the two groups had diverged, with the discomfort group improving by almost 1 point on the scale, whereas the performance of the comfort group declined. No significant differences emerged between the discomfort and nonexercising groups, the researchers reported.

The investigators found, counterintuitively, that some people in the study who did not record exercising did as well as those in the discomfort group,

Dr. McDermott noted that the nonexercise group was smaller than the discomfort group, making firm comparisons between the two challenging to draw. In addition, people whose exercise was not recorded were not asked to take it easy whenever they walked, unlike those in the comfort group. As a result, she said, some people in this group may have walked vigorously.

Dr. McDermott emphasized that these benefits occurred at home rather than at medical centers that can be difficult for some people to visit regularly.

“It’s always good to have this kind of information for patients, to show them that it’s possible for them to continue to improve,” said Jonathan Ehrman, PhD, associate director of preventive cardiology at Henry Ford Medical Center, Detroit. Dr. Ehrman was not involved in this study but said that he is contemplating running a similar home-based study that would use video rather than telephone support for patients.

“There’s emerging data about walking speed being related to longevity and predicting better outcomes in cardiac surgeries,” Dr. Ehrman said. “It seems to be, if you can get people walking faster or they have a better walking pace, related to better health outcomes.”

Dr. McDermott reported relationships with Regeneron, Helixmith, Mars, ArtAssist, ReserveAge, and Hershey. Dr. Ehrman reported no relevant financial conflicts of interest.

“You have to push yourself and get those uncomfortable symptoms, or else you probably won’t get gains,” said Mary McDermott, MD, professor of medicine at Northwestern University, Chicago, and the senior author of the study.

Walking for exercise is critical for people with lower-extremity PAD, Dr. McDermott said, but leg pain dissuades many people with the condition from doing so. She said her group hopes that showing the payoff of the “no pain, no gain” approach gives people with PAD the resolve to walk regularly, even when it’s hard.

The new study, a post hoc analysis of the LITE (Low-Intensity Exercise Intervention in PAD) trial, found that low-intensity exercise did not improve the symptoms of PAD but high-intensity exercise did.

Dr. McDermott and her colleagues compared 109 people with PAD who walked fast enough to cause discomfort versus 101 people who walked at a comfortable pace and 54 people who did not exercise at all. The average age was 69 years, 48% of participants were women, and 61% were Black.

Everyone in the exercise groups walked at home, with visits to a medical center early in the study to get exercise tips and then phone support from exercise coaches throughout the remainder of the study. Researchers encouraged those in the discomfort group to walk fast enough to cause significant pain in their legs, for up to 10 minutes or as long as they could. They then rested before walking again, ideally up to five times per day for 5 days per week.

At 6 months, people in the discomfort group were walking 0.056 m/sec faster than those in the comfort group during a 4-meter walking test (95% confidence interval [CI], 0.19-0.094 m/sec; P < .01), a gap that had grown by 12 months to 0.084 m/sec (95% CI, 0.049-0.120 m/sec; P <.01), according to the researchers. A statistically significant gap also emerged between the discomfort and nonexercising group at 6 months, but it eventually closed.

“It’s a question that people have asked for some time: Is it necessary to get that ischemic pain when you walk?” Dr. McDermott said. “This is the first well-powered clinical trial to provide a definitive answer on that, and the answer is that you do need that discomfort. It wasn’t even close.” Indeed, Dr. McDermott said, it’s possible that walking merely to the point of comfort and never pushing beyond it may harm people with PAD.

At the 6-month mark, the researchers found no statistical difference between the discomfort and comfort groups on a cumulative scale of usual walking speed, ability to rise from a chair, and ability to maintain balance in several positions. By 12 months, the two groups had diverged, with the discomfort group improving by almost 1 point on the scale, whereas the performance of the comfort group declined. No significant differences emerged between the discomfort and nonexercising groups, the researchers reported.

The investigators found, counterintuitively, that some people in the study who did not record exercising did as well as those in the discomfort group,

Dr. McDermott noted that the nonexercise group was smaller than the discomfort group, making firm comparisons between the two challenging to draw. In addition, people whose exercise was not recorded were not asked to take it easy whenever they walked, unlike those in the comfort group. As a result, she said, some people in this group may have walked vigorously.

Dr. McDermott emphasized that these benefits occurred at home rather than at medical centers that can be difficult for some people to visit regularly.

“It’s always good to have this kind of information for patients, to show them that it’s possible for them to continue to improve,” said Jonathan Ehrman, PhD, associate director of preventive cardiology at Henry Ford Medical Center, Detroit. Dr. Ehrman was not involved in this study but said that he is contemplating running a similar home-based study that would use video rather than telephone support for patients.

“There’s emerging data about walking speed being related to longevity and predicting better outcomes in cardiac surgeries,” Dr. Ehrman said. “It seems to be, if you can get people walking faster or they have a better walking pace, related to better health outcomes.”

Dr. McDermott reported relationships with Regeneron, Helixmith, Mars, ArtAssist, ReserveAge, and Hershey. Dr. Ehrman reported no relevant financial conflicts of interest.

‘Striking’ disparities in CVD deaths persist across COVID waves

Article Type

Fri, 07/29/2022 - 14:38

Cardiovascular disease (CVD) mortality rose significantly during the COVID-19 pandemic and persists more than 2 years on and, once again, Blacks and African Americans have been disproportionately affected, an analysis of death certificates shows.

The findings “suggest that the pandemic may reverse years or decades of work aimed at reducing gaps in cardiovascular outcomes,” Sadeer G. Al-Kindi, MD, Case Western Reserve University, Cleveland, said in an interview.

Although the disparities are in line with previous research, he said, “what was surprising is the persistence of excess cardiovascular mortality approximately 2 years after the pandemic started, even during a period of low COVID-19 mortality.”

“This suggests that the pandemic resulted in a disruption of health care access and, along with disparities in COVID-19 infection and its complications, he said, “may have a long-lasting effect on health care disparities, especially among vulnerable populations.”

The study was published online in Mayo Clinic Proceedings with lead author Scott E. Janus, MD, also of Case Western Reserve University.
 

Impact consistently greater for Blacks

Dr. Al-Kindi and colleagues used 3,598,352 U.S. death files to investigate trends in deaths caused specifically by CVD as well as its subtypes myocardial infarction, stroke, and heart failure (HF) in 2018 and 2019 (prepandemic) and the pandemic years 2020 and 2021. Baseline demographics showed a higher percentage of older, female, and Black individuals among the CVD subtypes of interest.

Overall, there was an excess CVD mortality of 6.7% during the pandemic, compared with prepandemic years, including a 2.5% rise in MI deaths and an 8.5% rise in stroke deaths. HF mortality remained relatively steady, rising only 0.1%.

Subgroup analyses revealed “striking differences” in excess mortality between Blacks and Whites, the authors noted. Blacks had an overall excess mortality of 13.8% versus 5.1% for Whites, compared with the prepandemic years. The differences were consistent across subtypes: MI (9.6% vs. 1.0%); stroke (14.5% vs. 6.9%); and HF (5.1% vs. –1.2%; P value for all < .001).

When the investigators looked at deaths on a yearly basis with 2018 as the baseline, they found CVD deaths increased by 1.5% in 2019, 15.8% in 2020, and 13.5% in 2021 among Black Americans, compared with 0.5%, 5.1%, and 5.7%, respectively, among White Americans.

Excess deaths from MI rose by 9.5% in 2020 and by 6.7% in 2021 among Blacks but fell by 1.2% in 2020 and by 1.0% in 2021 among Whites.

Disparities in excess HF mortality were similar, rising 9.1% and 4.1% in 2020 and 2021 among Blacks, while dipping 0.1% and 0.8% in 2020 and 2021 among Whites.

The “most striking difference” was in excess stroke mortality, which doubled among Blacks compared with whites in 2020 (14.9% vs. 6.7%) and in 2021 (17.5% vs. 8.1%), according to the authors.
 

Awareness urged

Although the disparities were expected, “there is clear value in documenting and quantifying the magnitude of these disparities,” Amil M. Shah, MD, MPH, of Harvard Medical School and Brigham and Women’s Hospital, both in Boston, said in an interview.

In addition to being observational, the main limitation of the study, he noted, is the quality and resolution of the death certificate data, which may limit the accuracy of the cause of death ascertainment and classification of race or ethnicity. “However, I think these potential inaccuracies are unlikely to materially impact the overall study findings.”

Dr. Shah, who was not involved in the study, said he would like to see additional research into the diversity and heterogeneity in risk among Black communities. “Understanding the environmental, social, and health care factors – both harmful and protective – that influence risk for CVD morbidity and mortality among Black individuals and communities offers the promise to provide actionable insights to mitigate these disparities.”

“Intervention studies testing approaches to mitigate disparities based on race/ethnicity” are also needed, he added. These may be at the policy, community, health system, or individual level, and community involvement in phases will be essential.”

Meanwhile, both Dr. Al-Kindi and Dr. Shah urged clinicians to be aware of the disparities and the need to improve access to care and address social determinants of health in vulnerable populations.

These disparities “are driven by structural factors, and are reinforced by individual behaviors. In this context, implicit bias training is important to help clinicians recognize and mitigate bias in their own practice,” Dr. Shah said. “Supporting diversity, equity, and inclusion efforts, and advocating for anti-racist policies and practices in their health systems” can also help.

Dr. Al-Kindi and Dr. Shah disclosed no relevant financial relationships.

Remnant cholesterol captures residual CV risk in patients with T2D

Article Type
Changed
Thu, 12/15/2022 - 14:28

Adding to a growing body of evidence that elevated remnant cholesterol (remnant-C) provides additional and independent risk prediction for major cardiovascular events (MACE), a new analysis has this shown this biomarker has prognostic value specifically in patients with type 2 diabetes (T2D).

In a post hoc analysis of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial, each standard-deviation increase in remnant-C was associated with a 7% increased risk in MACE (P = .004) after adjustment for several risk factors including other cholesterol values.

“In type 2 diabetes, remnant-C levels are associated with MACE regardless of LDL-C,” reported a team of investigators led by Liyao Fu, MD, Second Xiangya Hospital of Central South University, Changsha, China .

Remnant-C is one component of triglyceride-rich lipoproteins. Within triglyceride-rich lipoproteins, remnant-C has become a major focus of efforts to explain cardiovascular (CV) residual risk, according to the investigators.

Residual risk is a term used to explain why cardiovascular events occur after all known modifiable factors, such as LDL cholesterol (LDL-C), are controlled.

“Our primary findings indicate that baseline estimated remnant-C levels were associated with MACE regardless of clinical phenotypes, lifestyle confounders relative to CV risk, and lipid-lowering treatment,” said the authors of the analysis.

In the post hoc analysis of the ACCORD trial, which evaluated the effects of intensive glucose lowering in T2D more than 10 years ago, there were data on remnant-C over a median of 8.8 years of follow-up in 9,650 T2D patients. Over this period, 1,815 (17.8%) developed MACE.

Multiple analyses support prognostic value of remnant-C

In addition to the 7% rise in MACE for each standard-deviation increase in remnant-C when calculated as a continuous variable, other analyses told the same story.

This included an assessment by remnant-C tertiles. Not only was there a significant trend (P < .001) for greater risk with each higher baseline tertile of remnant-C, those in the highest tertile had a 38% greater risk of MACE relative to those in the lowest tertile (hazard ratio, 1.38; P < .001) after adjustment for confounders.

The same pattern was seen for several components of MACE, such as CV death and nonfatal myocardial infarction, when remnant-C tertiles were compared.

Visit-to-visit variability in remnant-C over the course of follow-up was also associated with greater risk of MACE. In logarithmic calculations, the risk of MACE climbed about 40% across all three models of risk adjustment. These models included adjustments for different sets of confounders, such as sex, age, blood pressure, CV disease history, and glucose levels. On an unadjusted basis, the risk was increased about 50% (HR, 1.52; P < .001).

For visit-to-visit variability in remnant-C, the greatest effect was on risk of nonfatal MI across models. In model 3, for example, which adjusted for the most confounders, the risk was nearly doubled (HR, 1.92; P < .001). In contrast, there did not appear to be a link between visit-to-visit variability and nonfatal stroke.

In a discordant analysis that was conducted to examine the relative risk of remnant-C independent of LDL-C, those who had a remnant-C level of at least 31 mg/dL were found to have a higher risk of MACE regardless of LDL-C level. Yet, the risk was higher if both remnant-C and LDL-C were elevated. For example, the risk was increased 22% for those with LDL-C at or below 100 mg/dL and remnant-C levels of at least 31 mg/dL (HR, 1.22; P = .015) but climbed to 37% for those with LDL-C above 100 mg/dL if remnant-C was at least 31 mg/dL (HR, 1.38; P = .007).
 

 

 

Remnant-C shows prognostic value in other risk groups

Although this study suggests an important prognostic value for remnant-C in T2D, there are numerous studies suggesting that it has prognostic value in other risk groups, such as those with a history of CV disease. This includes a study published earlier this year with 10 years of follow-up in 41,928 patients in Denmark. When combined with other risk factors, remnant-C substantially improved the accuracy of risk of events over time.

The investigators from this previous study, like the new study in patients with T2D, predict that remnant-C will be eventually included in guidelines.

According to Shi Tai, MD, a coauthor of the T2D study, remnant-C “may allow for the development of specific preventive and therapeutic approaches” to CV risk in patients with T2D.

T2D patients “with elevated plasma remnant-C levels represent a special population that deserves more attention regarding residual risk,” said Dr. Tai of the department of cardiovascular medicine at the Hospital of South Central China.
 

Great interest, but ready for guidelines?

This is an important direction of ongoing research, according to Christie M. Ballantyne, MD, professor of medicine, Baylor College of Medicine, Houston.

“There is a great deal of interest from both clinicians and trialists to find a simple way to identify patients with high residual risk who are on statin therapy,” he said. He thinks remnant-C has promise in this regard.

“Remnant-C is not in current guidelines,” he said in an interview, but he suggested that there is now a substantial body of evidence to suggest that it might be added if validated in further studies.

“Remnant-C is easy to calculate and may be helpful in practice now to identify patients who need more aggressive therapy to reduce risk and may be useful to identify patients for clinical trials who will benefit from new therapies that are in development,” he said.

However, the clinical relevance of therapies addressed at triglyceride-rich lipoproteins in general or their components, including triglycerides or remnant-C, has never been demonstrated, pointed out Peter W.F. Wilson, MD, PhD.

“Higher fasting or nonfasting triglyceride levels or their surrogates have been shown to be associated with increased risk for cardiovascular disease events in observational studies, but the importance of such measurements in persons already treated with very aggressive LDL-C lowering therapy is not known,” commented Dr. Wilson, director of epidemiology and genomic medicine, Emory School of Medicine, Atlanta.

Dr. Wilson was the coauthor of an editorial that accompanied the previously published Danish study of remnant-C. In his editorial, he suggested that remnant-C has promise for better understanding residual risk, but when contacted about these latest data he emphasized a lack of support so far for clinical relevance.

“Unfortunately, clinical trials have generally not shown that triglyceride lowering [to favorably alter remnant-C] in this situation favorably affects the risk of CV disease events,” he said in an interview. This does not preclude remnant-C as a targetable risk factor, but these data are needed.

Dr. Fu, Dr. Tai, and Dr. Wilson report no potential conflicts of interest. Dr. Ballantyne has financial relationships with more than 25 pharmaceutical companies, including several that produce products employed for the treatment of lipid abnormalities.

“Our primary findings indicate that baseline estimated remnant-C levels were associated with MACE regardless of clinical phenotypes, lifestyle confounders relative to CV risk, and lipid-lowering treatment,” said the authors of the analysis.

In the post hoc analysis of the ACCORD trial, which evaluated the effects of intensive glucose lowering in T2D more than 10 years ago, there were data on remnant-C over a median of 8.8 years of follow-up in 9,650 T2D patients. Over this period, 1,815 (17.8%) developed MACE.

Multiple analyses support prognostic value of remnant-C

In addition to the 7% rise in MACE for each standard-deviation increase in remnant-C when calculated as a continuous variable, other analyses told the same story.

This included an assessment by remnant-C tertiles. Not only was there a significant trend (P < .001) for greater risk with each higher baseline tertile of remnant-C, those in the highest tertile had a 38% greater risk of MACE relative to those in the lowest tertile (hazard ratio, 1.38; P < .001) after adjustment for confounders.

The same pattern was seen for several components of MACE, such as CV death and nonfatal myocardial infarction, when remnant-C tertiles were compared.

Visit-to-visit variability in remnant-C over the course of follow-up was also associated with greater risk of MACE. In logarithmic calculations, the risk of MACE climbed about 40% across all three models of risk adjustment. These models included adjustments for different sets of confounders, such as sex, age, blood pressure, CV disease history, and glucose levels. On an unadjusted basis, the risk was increased about 50% (HR, 1.52; P < .001).

For visit-to-visit variability in remnant-C, the greatest effect was on risk of nonfatal MI across models. In model 3, for example, which adjusted for the most confounders, the risk was nearly doubled (HR, 1.92; P < .001). In contrast, there did not appear to be a link between visit-to-visit variability and nonfatal stroke.

In a discordant analysis that was conducted to examine the relative risk of remnant-C independent of LDL-C, those who had a remnant-C level of at least 31 mg/dL were found to have a higher risk of MACE regardless of LDL-C level. Yet, the risk was higher if both remnant-C and LDL-C were elevated. For example, the risk was increased 22% for those with LDL-C at or below 100 mg/dL and remnant-C levels of at least 31 mg/dL (HR, 1.22; P = .015) but climbed to 37% for those with LDL-C above 100 mg/dL if remnant-C was at least 31 mg/dL (HR, 1.38; P = .007).
 

 

 

Remnant-C shows prognostic value in other risk groups

Although this study suggests an important prognostic value for remnant-C in T2D, there are numerous studies suggesting that it has prognostic value in other risk groups, such as those with a history of CV disease. This includes a study published earlier this year with 10 years of follow-up in 41,928 patients in Denmark. When combined with other risk factors, remnant-C substantially improved the accuracy of risk of events over time.

The investigators from this previous study, like the new study in patients with T2D, predict that remnant-C will be eventually included in guidelines.

According to Shi Tai, MD, a coauthor of the T2D study, remnant-C “may allow for the development of specific preventive and therapeutic approaches” to CV risk in patients with T2D.

T2D patients “with elevated plasma remnant-C levels represent a special population that deserves more attention regarding residual risk,” said Dr. Tai of the department of cardiovascular medicine at the Hospital of South Central China.
 

Great interest, but ready for guidelines?

This is an important direction of ongoing research, according to Christie M. Ballantyne, MD, professor of medicine, Baylor College of Medicine, Houston.

“There is a great deal of interest from both clinicians and trialists to find a simple way to identify patients with high residual risk who are on statin therapy,” he said. He thinks remnant-C has promise in this regard.

“Remnant-C is not in current guidelines,” he said in an interview, but he suggested that there is now a substantial body of evidence to suggest that it might be added if validated in further studies.

“Remnant-C is easy to calculate and may be helpful in practice now to identify patients who need more aggressive therapy to reduce risk and may be useful to identify patients for clinical trials who will benefit from new therapies that are in development,” he said.

However, the clinical relevance of therapies addressed at triglyceride-rich lipoproteins in general or their components, including triglycerides or remnant-C, has never been demonstrated, pointed out Peter W.F. Wilson, MD, PhD.

“Higher fasting or nonfasting triglyceride levels or their surrogates have been shown to be associated with increased risk for cardiovascular disease events in observational studies, but the importance of such measurements in persons already treated with very aggressive LDL-C lowering therapy is not known,” commented Dr. Wilson, director of epidemiology and genomic medicine, Emory School of Medicine, Atlanta.

Dr. Wilson was the coauthor of an editorial that accompanied the previously published Danish study of remnant-C. In his editorial, he suggested that remnant-C has promise for better understanding residual risk, but when contacted about these latest data he emphasized a lack of support so far for clinical relevance.

“Unfortunately, clinical trials have generally not shown that triglyceride lowering [to favorably alter remnant-C] in this situation favorably affects the risk of CV disease events,” he said in an interview. This does not preclude remnant-C as a targetable risk factor, but these data are needed.

Dr. Fu, Dr. Tai, and Dr. Wilson report no potential conflicts of interest. Dr. Ballantyne has financial relationships with more than 25 pharmaceutical companies, including several that produce products employed for the treatment of lipid abnormalities.

Adding to a growing body of evidence that elevated remnant cholesterol (remnant-C) provides additional and independent risk prediction for major cardiovascular events (MACE), a new analysis has this shown this biomarker has prognostic value specifically in patients with type 2 diabetes (T2D).

In a post hoc analysis of the Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial, each standard-deviation increase in remnant-C was associated with a 7% increased risk in MACE (P = .004) after adjustment for several risk factors including other cholesterol values.

“In type 2 diabetes, remnant-C levels are associated with MACE regardless of LDL-C,” reported a team of investigators led by Liyao Fu, MD, Second Xiangya Hospital of Central South University, Changsha, China .

Boosting hypertension screening, treatment would cut global mortality 7%

Article Type

Wed, 07/27/2022 - 14:20

If 80% of individuals with hypertension were screened, 80% received treatment, and 80% then reached guideline-specified targets, up to 200 million cases of cardiovascular disease (CVD) and 130 million deaths could be averted by 2050, a modeling study suggests.

Achievement of the 80-80-80 target “could be one of the single most important global public health accomplishments of the coming decades,” according to the authors.

“We need to reprioritize hypertension care in our practices,” principal investigator David A. Watkins, MD, MPH, University of Washington, Seattle, told this news organization. “Only about one in five persons with hypertension around the world has their blood pressure well controlled. Oftentimes, clinicians are focused on addressing patients’ other health needs, many of which can be pressing in the short term, and we forget to talk about blood pressure, which has more than earned its reputation as ‘the silent killer.’ ”

The modeling study was published online  in Nature Medicine, with lead author Sarah J. Pickersgill, MPH, also from the University of Washington.
 

Two interventions, three scenarios

Dr. Watkins and colleagues based their analysis on two approaches to blood pressure (BP) control shown to be beneficial: drug treatment to a systolic BP of either 130 mm Hg or 140 mm Hg or less, depending on local guidelines, and dietary sodium reduction, as recommended by the World Health Organization.

The team modeled the impacts of these interventions in 182 countries according to three scenarios:

  • Business as usual (control): allowing hypertension to increase at historic rates of change and mean sodium intake to remain at current levels
  • Progress: matching historically high-performing countries (for example, accelerating hypertension control by about 3% per year at intermediate levels of intervention coverage) while lowering mean sodium intake by 15% by 2030
  • Aspirational: hypertension control achieved faster than historically high-performing countries (about 4% per year) and mean sodium intake decreased by 30% by 2027

The analysis suggests that in the progressive scenario, all countries could achieve 80-80-80 targets by 2050 and most countries by 2040; the aspirational scenario would have all countries meeting them by 2040. That would result in reductions in all-cause mortality of 4%-7% (76 million to 130 million deaths averted) with progressive and aspirational interventions, respectively, compared with the control scenario.

There would also be a slower rise in expected CVD from population growth and aging (110 million to 200 million cases averted). That is, the probability of dying from any CVD cause between the ages of 30 and 80 years would be reduced by 16% in the progressive scenario and 26% in the aspirational scenario.

Of note, about 83%-85% of the potential mortality reductions would result from scaling up hypertension treatment in the progressive and aspirational scenarios, respectively, with the remaining 15%-17% coming from sodium reduction, the researchers state.

Further, they propose, scaling up BP interventions could reduce CVD inequalities across countries, with low-income and lower-middle-income countries likely experiencing the largest reductions in disease rates and mortality.
 

Implementation barriers

“Health systems in many low- and middle-income countries have not traditionally been set up to succeed in chronic disease management in primary care,” Dr. Watkins noted. For interventions to be successful, he said, “several barriers need to be addressed, including: low population awareness of chronic diseases like hypertension and diabetes, which leads to low rates of screening and treatment; high out-of-pocket cost and low availability of medicines for chronic diseases; and need for adherence support and provider incentives for improving quality of chronic disease care in primary care settings.”

“Based on the analysis, achieving the 80-80-80 seems feasible, though actually getting there may be much more complicated. I wonder whether countries have the resources to implement the needed policies,” Rodrigo M. Carrillo-Larco, MD, researcher, department of epidemiology and biostatistics, School of Public Health, Imperial College London, told this news organization.

“It may be challenging, particularly after COVID-19, which revealed deficiencies in many health care systems, and care for hypertension may have been disturbed,” said Dr. Carrillo-Larco, who is not connected with the analysis.

That said, simplified BP screening approaches could help maximize the number of people screened overall, potentially identifying those with hypertension and raising awareness, he proposed. His team’s recent study showed that such approaches vary from country to country but are generally reliable and can be used effectively for population screening.

In addition, Dr. Carrillo-Larco said, any efforts by clinicians to improve adherence and help patients achieve BP control “would also have positive effects at the population level.”

The study was supported by a grant from the Bill & Melinda Gates Foundation, with additional funding by a grant to Dr. Watkins from Resolve to Save Lives. No conflicts of interest were declared.
