This study is a randomized controlled trial, single-center study in HFrEF patients, that held in Universitas Sebelas Maret Hospital, Central Java, Indonesia. The investigators divided 26 HFrEF patients consecutively into two groups, the first is the rapid up-titration group, which will get carvedilol up-titration every day, 3.125mg twice daily on the first day, 6.125mg twice daily on the second day, 12.5mg twice daily on the third day and 25mg twice daily on the fourth day consecutively. And the second group will have carvedilol titration according to established guidelines on Heart Failure, start 3.125mg twice daily, and up titrated every 2 weeks. Every patient will be checked for IL-6, TNF-α, NT-ProBNP, MDA, left ventricular Ejection Fraction, six minutes walking test, and Kansas City Cardiomyopathy Questionnaire on day 1, pre-discharge, and one month after hospitalization. The study was approved by the university ethics committee. The clinical parameters evaluated at admission were analyzed using variable comparative with Shapiro Wilk or one-way ANOVA, with three intervals analysis using repeated ANOVA (p<0.05).
Guidelines-directed medical therapy has improved dramatically outcomes in heart failure with reduced ejection fraction (HFrEF) patients. Beta-blockers have the most beneficial effects on all caused mortality and rehospitalization on HFrEF, but unfortunately, since the discovery of beta-blocker therapy in HFrEF, there was no change in the way of titration, start low go slow, which resulted in difficulties in reaching optimal doses for some patients.
