Positive effect of if-channel’s blocker ivabradine therapy in a patient with ischemic chronic heart failure with preserved left ventricle ejection fraction and hereditary thrombophilia (clinical case)

Abstract

Chronic heart failure is one of the leading causes of mortality among patients with cardiovascular diseases. Current therapeutic methods for treating patients with chronic heart failure do not always provide a significant improvement in main intermediate and final outcomes. According to the neurohumoral theory of chronic heart failure development, an antagonism of the sympathoadrenal system with b-blockers is pathogenetically substantiated, and the drugs of this group are one of the first-line treatment for chronic heart failure. The selection of heart rate-reducing therapy in patients with chronic heart failure caused by ischemia, can often be difficult due to development of b-blockers side effects, b-blockers intolerance and/or due to the presence of contraindications at severe comorbid pathology. This article presents a clinical case of an effective administration of ivabradine, a drug of if-channel inhibitors group, in combination with b-blockers to a patient with chronic heart failure with a preserved ejection fraction.
