Background: Cardiac myosin inhibitors were recently developed to address the underlying pathophysiology of hypertrophic cardiomyopathy and to improve symptoms and quality of life. In this review, we evaluated the pharmacologic profile and clinical outcomes for mavacamten and aficamten, 2 cardiac myosin inhibitors investigated in symptomatic hypertrophic cardiomyopathy.
Methods And Results: Using a systematic search, 10 clinical trials with safety and efficacy data for either drug in obstructive hypertrophic cardiomyopathy (oHCM) and nonobstructive hypertrophic cardiomyopathy were included.
Background: Various measures of abnormal left atrial (LA) structure or function (LA myopathy) are associated with a higher risk of ischemic stroke and dementia, independent of atrial fibrillation. However, limited data exist on their prognostic usefulness. Therefore, we aimed to assess the ability of markers of LA myopathy to improve the prediction of ischemic stroke and dementia.

Objectives: The authors aimed to assess the prevalence, CV outcome risk, and treatment response to the sodium-glucose cotransporter 2 inhibitor (SGLT2i) dapagliflozin among patients with severe HF across the spectrum of left ventricular ejection fraction (LVEF) in DAPA-HF and DELIVER.
Methods: Severe HF was adapted from the ESC (European Society of Cardiology) HFA (Heart Failure Association) definition: NYHA functional class III/IV, evidence of HF with reduced, mildly reduced, or preserved LVEF, HF hospitalization within the previous 12 months, and adverse patient-reported symptom burden (Kansas City Cardiomyopathy Questionnaire-Total Symptoms Score <75).
