Clonidine and Left Ventricular Dysfunction
The objectives of this study are:
- To evaluate the effect of clonidine, a sympathetic modulator, to reverse cardiac remodeling and to improve hemodynamics in diastolic heart failure (DHF).
- To evaluate the effect of clonidine on neurohormones and quality of life in patients with DHF.
The study is a double-blind, placebo-controlled study evaluating the effects of clonidine compared to placebo in patients with DHF. A total of 70 patients with DHF will be randomized in a 1:1 ratio to:
- placebo (n=35) or to
- clonidine (n=35) in a dose of 0.075 mg twice a day for the first 6 weeks followed by uptitration to 0.150 mg twice a day for 6 months.
The primary outcome is the reversion of cardiac remodeling and hemodynamic parameters evaluated by magnetic resonance imaging (MRI) and echocardiography.
