Abstract
Ivabradine is a pure heart rate-lowering drug that acts directly on the sinus node and does not affect atrioventricular or intraventricular conduction times, myocardial contractility or ventricular repolarization. Ivabradine is used in the treatment of adults with New York Heart Association (NYHA) class II-IV chronic heart failure (CHF) with systolic dysfunction, in sinus rhythm, with a heart rate of ≥75 beats per minute (bpm). This report describes the beneficial effect of ivabradine on clinical parameters in a HIV-infected patient with dilated cardiomyopathy presenting with NYHA class III CHF symptoms. Ivabradine improved functional capacity and left ventricular (LV) systolic function in our patient with HIV-related dilated cardiomyopathy and CHF. This report also lists the summaries of potential clinically significant interaction, likely to require additional monitoring, alteration of drug dosage or timing of administration, between ivabradine and antiretroviral drugs.
