Randomized Clinical Trial: Aficamten improves peak oxygen uptake in symptomatic obstructive hypertrophic cardiomyopathy – N Engl J Med
27 May, 2024 | 20:24h | UTCStudy Design and Population: This phase 3, double-blind trial randomized 282 adults with symptomatic obstructive hypertrophic cardiomyopathy (HCM) to receive aficamten or placebo for 24 weeks. The primary outcome was the change in peak oxygen uptake, with secondary outcomes including changes in the Kansas City Cardiomyopathy Questionnaire score and New York Heart Association functional class.
Main Findings: Aficamten significantly increased peak oxygen uptake by 1.7 ml/kg/min (95% CI, 1.0 to 2.4; P<0.001) compared to placebo. Improvements were also seen in all secondary outcomes. The incidence of adverse events was similar between the groups.
Implications for Practice: Aficamten shows promise in improving exercise capacity and symptoms in patients with obstructive HCM, potentially offering a new therapeutic option. Further research may confirm its long-term benefits and safety.

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.
