摘要
心率是重要而容易观测的生命活动指标,影响着心血管疾病的预后。急性冠状动脉综合征是冠心病中最严重的临床类型和导致患者死亡的最主要原因。多个临床研究证实静息心率增快与急性冠状动脉综合征患者全因死亡率、心血管病死率等不良心血管事件密切相关。然而,静息心率的测量结果可重复性较差,夜间心率和非勺型心率可能具有更高的预测价值。多数临床研究表明控制心率药物可以改善患者的预后。
Heart rate is a simple and accessible cardiovascular parameter. An elevated heart rate correlates with cardiovascular mor- tality and is an independent risk factor for cardiovascular disease. Acute coronary syndrome （ACS） is the most severe clinical type of coronary heart disease and the leading cause of death. The association between elevated resting heart rate and all-cause mortality, cardiovascular morbidity and mortality in ACS population has been demonstrated in a large number of epidemiologic studies. However, discrepancies can be found for the methods of heart rate measurement. To date, heart rate reduction is a recognized strategy to prevent ischaemic episodes,whereas more randomized trials are expected to evaluate its benefit in ACS patients.
