很多的流行病学研究提示快心率在一般人群及各种心血管疾病人群中都联系着不良预后,这种联系在心率>80次min-1的时候已经比较明显。随着特异降心率药物的出现,单纯降低心率带来的获益也已经得到证实,另外,很多实验也已表明快的心率可能联系着血流动力学的改变、血管顺应性的下降、血管内皮功能受损、血管炎症反应并可能增加急性冠脉事件的发生。这些证据都表示,心率应该被列入心血管疾病的危险因子。
Many epidemiological studies suggest that fasting rate is associated with poor prognosis in the general population and in a variety of cardiovascular disease populations, and this association is evident when the heart rate is> 80 min-1. With the advent of drugs specific to the heart, the benefits of simply lowering heart rate have also been demonstrated. In addition, many experiments have shown that fast heart rates may be associated with changes in hemodynamics, decreased vascular compliance, vascular endothelium Impaired function, vascular inflammation and may increase the incidence of acute coronary events. The evidence shows that heart rate should be included in the risk factors for cardiovascular disease.
