Heart rate is a major determinant of cardiac output, myocardial oxygen consumption and coronary blood flow under physiological and pathological conditions. Experimental and clinical data have demonstrated that heart rate reduction is the main mechanism for reducing ischemia, improving left ventricular function, decreasing the risk of plaque rupture and post myocardial infarction mortality. Nowadays betablockers are the best class of drugs that can lower heart rate in patients with cardiovascular diseases, but sometimes their use is limited by some contraindications. Ivabradine is a new drug that reduces the firing rate of pacemaker cells in the sinoatrial node through a different mechanism with respect to betablockers. The purpose of this review is to investigate the main trials that support Ivabradine adoption in clinical practice.
