Heart rate is a predictor of cardiovascular and all-cause mortality in the general population and in patients with cardiovascular disease. Increased resting heart rate multiplies risk and interferes at all stages of the cardiovascular disease continuum initiating from endothelial dysfunction and continuing via atherosclerotic lesion formation and plaque rupture to end-stage cardiovascular disease. As a therapeutic target, heart rate is accessible via numerous pharmacological interventions. The concept of selective heart rate reduction by the I(f) current inhibitor ivabradine provides an option to intervene effectively along the chain of events and to define the specific and prognostic role of heart rate for patients with coronary artery disease and heart failure. Future interventional studies will further clarify the significance of heart rate and targeted heart rate reduction for primary and secondary prevention in cardiovascular and cerebrovascular events.
心率是普通人群和心血管疾病患者心血管和全因死亡率的预测指标。静息心率增加会使风险倍增,并在心血管疾病连续体的各个阶段产生干扰,从内皮功能障碍开始,通过动脉粥样硬化病变形成和斑块破裂一直持续到终末期心血管疾病。作为一个治疗靶点,心率可以通过多种药物干预来控制。I(f)电流抑制剂伊伐布雷定的选择性心率降低概念为沿着事件链进行有效干预,并为冠心病和心力衰竭患者的心率提供特定的预后作用提供了一种选择。未来的干预性研究将进一步阐明心率和有针对性的心率降低在心血管和脑血管事件的一级和二级预防中的意义。
