Background: The beneficial role of high-intensity statins in secondary prevention of recurrent atherosclerotic stroke is well established. It is uncertain whether the observed benefit was from a reduction in the cholesterol level or to other pleotropic effects of atorvastatin. The ideal target cholesterol level for secondary prevention is unclear. This trial was conducted to help determine an ideal target LDL-C level in the prevention of CV events following ischemic stroke.

Study design: Randomized, parallel-group, event-driven trial.

Setting: Conducted in France and South Korea.

Synopsis: In this study, patients with an ischemic stroke within the last 3 months or TIAs within 15 days were randomly assigned to receive statins with or without ezetimibe (Zetia) to achieve a higher-target LDL-C level (90-110 mg/dL) vs. lower-target LDL-C (less than 70 mg/dL). The composite primary endpoint was a major cardiovascular event, which included ischemic stroke, MI, new symptoms leading to urgent coronary or carotid revascularization, or death from CV causes.

There were 2,860 patients enrolled, 1,430 were assigned to each target group. At the end of 3.5 years, the primary endpoint occurred in 8.5% of patients in the lower target group, compared with 10.9% in the higher target group (hazard ratio, 0.78; 95% confidence interval, 0.61-0.98; P = .04). Unfortunately, the trial was stopped early because of a lack of funding.

Bottom line: Using medications including statins to lower the LDL-C to less than 70 mg/dL leads to better cardiovascular outcomes following ischemic stroke.

Background: Guideline-directed medical therapy (use of beta-blockers, ACE inhibitor/angiotensin receptor blockers, and mineralocorticoid antagonists) provides clear benefits on mortality and morbidity in patients with HFrEF. Dapagliflozin (Farxiga) belongs to a class of sodium-glucose transporter 2 (SGLT2) inhibitors that inhibits reabsorption of sodium and glucose in the kidney and treats type 2 diabetes. This new class of drugs is emerging as an effective tool in the management of HFrEF based on the recent publication of the primary results of the DAPA-HF trial (Study to Evaluate the Effect of Dapagliflozin on the Incidence of Worsening Heart Failure or Cardiovascular Death in Patients with Chronic Heart Failure). It demonstrated substantial benefits in terms of heart failure symptoms, hospitalizations, and mortality when added to triple therapy for patients with chronic HFrEF regardless of the presence of diabetes.

Study design: Randomized, controlled double-blind trials.

Setting: 410 participating institutions in 20 countries.

Synopsis: Men and women aged 18 years and older with HFrEF who had New York Heart Association (NYHA) functional class II or higher, and optimally treated with pharmacologic and device therapy for HF were randomized to receive dapagliflozin or placebo. A total of 4,744 patients, aged 22-94 years were enrolled in the study.

• Dapagliflozin showed a clinically significant benefit on health status (symptoms, physical function, and quality of life). Improved health-related quality of life (as measured by the well-validated Kansas City Cardiomyopathy Questionnaire score) with dapagliflozin in comparison with placebo was sustained for more than 8 months.
• Dapagliflozin reduced the risk of death and worsening heart failure and improved symptoms across the broad spectrum of ages studied in DAPA-HF. There was no significant imbalance in tolerability or safety events between dapagliflozin and placebo, even in elderly individuals.

Bottom line: Follow-up DAPA-HF studies further support the role of SGLT2 inhibitor dapagliflozin in improving mortality, reducing hospitalization, and improving the quality of life in patients with HFrEF and is considered a safe option across all age groups.
