The ODYSSEY-HCM trial found that mavacamten did not significantly improve exercise capacity or patient-reported outcomes in individuals with symptomatic nonobstructive hypertrophic cardiomyopathy. Safety concerns emerged, including more frequent reductions in ejection fraction and treatment interruptions among those receiving mavacamten. The trial's limited diversity and short duration raise questions about the generalizability and long-term implications of the findings. Despite the lack of approved therapies for this patient group, the study underscores the complexity of using surrogate endpoints and the need for deeper exploration into disease mechanisms and treatment response.

In this interview, Matthew Martinez MD, FACC and Milind Y. Desai, MD, MBA, FACC discuss “ODYSSEY-HCM: Mavacamten in nHCM.”

The DAN-RSV trial is one of the largest individually randomized studies ever conducted, enrolling over 131,000 participants aged 60 and older to evaluate the effectiveness of the RSVpreF vaccine. Using a pragmatic design with electronic consent and national health registry data, the trial successfully met its primary objective of reducing RSV-related respiratory tract disease hospitalizations. It also achieved all key secondary endpoints, showing favorable outcomes for RSV-related and all-cause respiratory and cardiorespiratory hospitalizations. These results demonstrate the vaccine’s potential to significantly impact public health and inform future RSV vaccine policy.

In this interview, Drs. Richard A. Chazal and Tor Biering-Sørensen discuss “DAN-RSV: RSVpreF Vaccine for Preventing Cardiorespiratory Hospitalizations.”

Adverse pregnancy outcomes (APOs), affecting up to 20% of pregnancies, serve as early indicators of a woman’s future cardiovascular risk and should be treated as critical markers in preventive care. Pregnancy offers a unique opportunity—a “window”—to identify and address cardiovascular vulnerabilities, making routine screening for heart health essential at every clinical encounter. Long-term monitoring beyond the postpartum period is vital, as cardiovascular risks persist and evolve over time. Improving women’s heart health requires a collaborative, lifelong approach across specialties, integrating cardiology with obstetrics and primary care. This comprehensive strategy ensures that prevention remains central during and after reproduction.

In this interview, Drs. Alison L. Bailey, MD, FACC and Ijeoma Isiadinso, MD, FACC discuss “The Role of Prevention During & After Reproduction”.
