The Role of Medical Therapy in Hypertrophic Cardiomyopathy: An Updated Review. (PubMed, Heart Fail Clin) - "Emerging therapies, including sodium-glucose cotransporter 2 inhibitors, sacubitril/valsartan, and ninerafaxstat, show promising benefits. Proper management of related conditions such as atrial fibrillation and heart failure is also essential. A comprehensive approach that considers individual patient characteristics and the specific subtype of HCM is essential for achieving optimal outcomes."

A de novo systematic literature review to identify the clinical effectiveness and safety of different treatments for patients with non-obstructive hypertrophic cardiomyopathy (HEART FAILURE 2025) - "A change in New York Heart Association (NYHA) class was reported in seven studies, all of which reported on 40 patients or fewer; within these the proportion of patients with ≥1 class improvement ranged from 14.7% (5/29) (ninerafaxstat arm of IMPROVE-HCM) to 79.4% (27/34) (aficamten arm of FOREST-HCM). There is a scarcity of rigorous studies reporting on non-obstructive HCM treatment and there is no significant evidence to support improved outcomes for traditional treatments, such as beta-blockers. Newer therapies which include cardiac myosin inhibitors (designed to address the underlying pathophysiology of HCM), are emerging as promising options with phase II studies demonstrating step changes in safety and efficacy, including NYHA functional class changes. Further research is needed to strengthen these findings, as current data remains limited."

(PubMed, Acta Diabetol) - "Pharmacological treatments like GLP-1 agonists, SGLT-2 inhibitors, NHE-1, NHE-3, and PPAR-γ agonists show promise for treating DCM. These treatments improve myocardial glucose absorption, address dysregulated glucose and lipid metabolism, and lower heart failure and cardiovascular events. Further research is needed to confirm effectiveness and safety."
