简要总结
The primary objective of this study is to investigate the effect of enavogliflozin, an Sodium-glucose transporter 2 (SGLT2) inhibitor, compared with placebo on left ventricular diastolic function in patients with nonobstructive hypertrophic cardiomyopathy. The secondary objective of this study is to investigate the effect of enavogliflozin on exercise capacity, symptoms, serum biomarkers, and arrhythmic burden in patients with nonobstructive hypertrophic cardiomyopathy.
详细描述
Most of the medication used in HCM(hypertrophic cardiomyopathy) targets dynamic left ventricular obstruction and hypercontractility. Guidelines recommend that beta-blockers and calcum channels can also be used to lower heart rate and improve diastolic function in symptomatic nonobstructive HCM(hypertrophic cardiomyopathy), and that diuretics may be considered next, but there is a paucity of evidence supporting these recommendations. Left ventricular diastolic dysfunction is the main pathophysiological mechanism in nonobstructive HCM. SGLT2(Sodium-glucose transporter 2) inhibitors have been shown to reduce heart failure events and mortality in patients with heart failure with preserved ejection fraction, and have also been reported to improve left ventricular diastolic function. This study will investigate the efficacy and safety of enavogliflozin, an SGLT2(Sodium-glucose transporter 2) inhibitor, compared with placebo in patients with nonobstructive hypertrophic cardiomyopathy, over a period of 6 months.
Patients with hypertrophic cardiomyopathy and without evidence of dynamic left ventricular outflow tract obstruction at resting or on provocation by Valsalva maneuver or exercise will be enrolled. Participants will be randomly assigned to the enavogliflozin 0.3mg group and the placebo group in a 1:1 ratio and will continue the medication for 24 weeks. Changes in left ventricular diastolic reserve assessed by diastolic stress echocardiography will be compared between the treatment groups at 24 weeks. Changes in other parameters of diastolic function and exercise capacity will be assessed by diastolic stress echocardiography and compared between the treatment groups. Symptom status, serum biomarker levels, and arrhythmic burden on 24 hour ambulatory electrocardiogram will also be compared between the treatment groups. Post-trial follow-up will be performed at 52 weeks.
