2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for the Management of Hypertrophic Cardiomyopathy – J Am Coll Cardiol
11 May, 2024 | 14:20h | UTCIn a significant advancement for the treatment of hypertrophic cardiomyopathy (HCM), the American Heart Association and the American College of Cardiology, along with other leading societies, have released updated guidelines to optimize patient care. Here are the essential updates and recommendations for practicing physicians:
1 – Updated Diagnostic Strategies: The guideline emphasizes the use of advanced imaging techniques and genetic testing to enhance diagnostic accuracy, enabling personalized treatment approaches.
2 – Risk Assessment Tools: Revised tools for sudden cardiac death (SCD) risk assessment are detailed, aiding clinicians in making informed decisions regarding the use of implantable cardioverter-defibrillators (ICDs).
3 – Management of Obstructive HCM: New recommendations for the pharmacological treatment of symptomatic obstructive HCM include the use of disopyramide and advanced therapies such as septal reduction when initial medication does not suffice.
4 – Guidelines on Exercise and Lifestyle: The guidelines provide a nuanced approach to physical activity, recognizing the benefits while outlining the risks for patients with HCM. Detailed advice is offered on managing competitive sports involvement and other lifestyle considerations.
5 – Multidisciplinary Approach: The guidelines advocate for a team-based approach involving specialized HCM centers, ensuring patients benefit from comprehensive expertise and the latest treatment modalities.
6 – Innovations in Treatment: Highlighting new therapeutic options like myosin inhibitors, the guidelines underscore their role in managing obstructive symptoms when traditional medications are inadequate.
7 – Special Populations: Detailed sections on the management of HCM in children and pregnant women, addressing the unique challenges these groups face.
These guidelines represent a cornerstone in the evolving landscape of HCM management, embodying a commitment to enhancing outcomes and quality of life for patients through evidence-based practices and collaborative care.

RCT: Empagliflozin does not reduce heart failure hospitalization or death post-myocardial infarction
29 Apr, 2024 | 12:39h | UTCThis randomized, placebo-controlled trial assessed empagliflozin in preventing heart failure or death in patients recently hospitalized for acute myocardial infarction. Among 6,522 patients divided evenly into empagliflozin and placebo groups, there was no significant difference in the primary outcome—a composite of heart failure hospitalization or death—after 17.9 months. The empagliflozin group saw 8.2% experiencing the primary outcome versus 9.1% in the placebo group, yielding a non-significant hazard ratio of 0.90 (95% CI, 0.76 to 1.06; P=0.21). The results indicate that empagliflozin does not effectively reduce the risk of heart failure or mortality compared to placebo in this setting.

RCT: Semaglutide significantly improves symptoms and weight loss in HFpEF and type 2 diabetes patients
29 Apr, 2024 | 12:36h | UTCThis randomized clinical trial evaluated the effects of semaglutide on 616 patients with obesity-related heart failure with preserved ejection fraction (HFpEF) and type 2 diabetes. Patients received weekly doses of 2.4 mg semaglutide or a placebo for 52 weeks. The study’s primary findings included a significant improvement in heart failure–related symptoms, as measured by the Kansas City Cardiomyopathy Questionnaire clinical summary score (average increase of 13.7 points in the semaglutide group versus 6.4 points in the placebo group). Additionally, semaglutide treatment resulted in a mean 9.8% reduction in body weight compared to 3.4% with placebo. Secondary outcomes also favored semaglutide, showing enhancements in 6-minute walk distance and reductions in C-reactive protein levels. Notably, semaglutide was associated with fewer serious adverse events compared to placebo.

RCT: Efficacy and safety of microaxial flow pump in STEMI-related cardiogenic shock
28 Apr, 2024 | 20:17h | UTCThis randomized clinical trial assessed the impact of a microaxial flow pump (Impella CP) on mortality in 355 patients with ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock. Patients were randomly assigned to receive either the microaxial flow pump plus standard care or standard care alone. The primary outcome was mortality at 180 days. Results showed a significant reduction in death rates in the microaxial flow pump group (45.8%) compared to the standard care group (58.5%) with a hazard ratio of 0.74 (95% CI, 0.55 to 0.99; P=0.04). However, the incidence of severe adverse events was notably higher in the microaxial flow pump group, including severe bleeding and device-related complications.

Pooled Analysis: Semaglutide improves symptoms and reduces weight in obesity-related heart failure with preserved ejection fraction
28 Apr, 2024 | 16:33h | UTCThis pooled analysis of the STEP-HFpEF and STEP-HFpEF DM randomized trials assessed the efficacy of semaglutide in 1,145 participants with obesity-related heart failure and preserved ejection fraction, across 129 research sites globally. Participants, who had a BMI of at least 30 kg/m2 and varied cardiovascular conditions, were administered 2.4 mg of semaglutide weekly for 52 weeks. Semaglutide significantly improved heart failure-related symptoms (7.5 points increase in KCCQ-CSS), reduced body weight by 8.4%, and increased the 6-min walk distance by 17.1 meters, compared to placebo. The treatment also demonstrated safety, with fewer serious adverse events than the placebo group. These benefits were consistent across various subgroups, confirming semaglutide’s potential as a treatment in this patient population.

M-A: Cardiovascular benefits of SGLT2 inhibitors in patients without diabetes
22 Mar, 2024 | 11:07h | UTCStudy Design and Population: This meta-analysis investigated the cardiovascular (CV) outcomes associated with sodium-glucose cotransporter-2 inhibitors (SGLT2i) in patients without diabetes mellitus (DM). By systematically reviewing online databases, the authors identified and included six randomized controlled trials (RCTs) in their analysis. These trials compared SGLT2i with placebo/control in a total of 12,984 participants, who were followed for an average duration of 17.7 months. The study population comprised mainly patients with heart failure (HF), chronic kidney disease, or myocardial infarction, with a mean age of 64 years, where 72% were men and the mean hemoglobin A1C level was 5.7%.
Main Findings: The use of SGLT2i was associated with a significant reduction in composite CV death or hospitalization for HF, with an odds ratio (OR) of 0.77 (95% confidence interval [CI], 0.68 to 0.87, p < 0.0001), primarily due to a decrease in hospitalization for HF (OR 0.70, 95% CI 0.60 to 0.81, p < 0.00001). No significant differences were observed in CV death, all-cause death, or major adverse CV events when comparing SGLT2i to placebo. Notably, serious adverse events were lower with the use of empagliflozin compared to placebo.
Implications for Practice: This meta-analysis highlights the significant CV benefits of SGLT2i treatment in reducing CV death or hospitalization for HF in patients without DM, compared with placebo. These findings suggest the potential for broader use of SGLT2i in populations without diabetes to improve cardiovascular outcomes.
