Heart Failure With Preserved Ejection Fraction, Hypertrophic Cardiomyopathy
Conditions
Brief summary
This study aims to evaluate the impact of Sodium-dependent glucose transporters 2 inhibitor Empagliflozin on the exercise capacity,symptoms of heart failure, cardiac function, myocardial remodeling and quality of life of nonobstructive HCM patients with HFpEF.
Interventions
Participants randomized to the study group will received Empagliflozin 10mg q.d. for 12 months.
