  • Title: Novel drugs for heart rate control in heart failure.
    Author: Bielecka-Dabrowa A, von Haehling S, Rysz J, Banach M.
    Journal: Heart Fail Rev; 2018 Jul; 23(4):517-525. PubMed ID: 29594814.
    Abstract:
    In patients with heart failure, increased sympathetic activity is associated with a positive chronotropic stimulation leading to accelerated resting heart rate. Elevated heart rate (HR) is a risk factor for cardiovascular events, both in the general population and in patients with heart failure. Ivabradine is a pure HR-lowering agent, and it does not affect myocardial contractility, blood pressure, intracardiac conduction, or ventricular repolarization. In clinical trials such as BEAUTIFUL, CARVIVA HF, SHIFT, and INTENSIFY in patients with systolic left ventricular dysfunction, heart rate reduction with ivabradine brought positive outcomes. However, the results of the recent meta-analysis are rather neutral. In a diabetes mouse model of heart failure with preserved ejection fraction (HFpEF), selective heart rate reduction by If inhibition improved vascular stiffness, left ventricular (LV) contractility, and diastolic function. However, EDIFY (Effect of ivabradine in patients with heart rate with preserved ejection fraction) trial show that the use of ivabradine in patients with HFpEF is not supported. The further clinical trials investigating the use of ivabradine in heart failure should be carried out.
