A Heart-Rate-Reducing Medication Reduces The Risk Of Heart Failure And Cardiac Fibrosis
The findings of a Montreal Heart Institute (MHI) study published in the scientific journal Cardiology suggest that ivabradine, a heart rate reduction medication, is also effective in reducing the risk of diastolic heart failure (left ventricular insufficiency) and cardiac fibrosis.
The benefits of slower heart rate on mortality and morbidity associated with cardiovascular disease no longer need to be demonstrated. In this study, titled "Heart Rate Reduction by Ivabradine Reduces Diastolic Dysfunction and Cardiac Fibrosis," researchers sought to determine the effectiveness of ivabradine in treating diastolic dysfunction of the left ventricle, a condition affecting 40% of people with heart failure.
According to Dr. Jean-Claude Tardif, Director of the MHI Research Centre and professor of medicine at the Universit© de Montr©al, the results are both interesting and encouraging. "The effectiveness of ivabradine in treating angina pectoris is now well known. However, few treatments are available to patients with diastolic heart failure. The beneficial effects of ivabradine demonstrated in laboratory suggest that this course of treatment should be further investigated." Clinical studies with subjects are expected to follow.
