Clinical Trial Summary

Beta-blockers improve clinical outcomes in heart failure and reduced ejection fraction (HFrEF); but not in those with preserved EF. Global longitudinal strain (GLS) is a prognostic factor independent of left ventricular ejection fraction (LVEF). In a retrospective with 1969 patients with HF and LVEF of ≥40%, beta-blocker was associated with improved survival in those with low GLS (GLS <14%), but not in those with GLS ≥14%. In this prospective, randomized clinical study, the investigators will assess the effect of slow-release carvedilol in patients with HFpEF and hypertension. The primary endpoint is the time-averaged proportional changes in NT-proBNP level and GLS change from baseline to month 6.
