摘要 目的探讨静息心率(RHR)与冠心病(CHD)的关系。方法选择132例CHD患者进行冠状动脉造影及RHR的测定,同时选择130例正常健康体检者测定RHR作为对照。结果CHD组的RHR(79.1±7.6次/min)快于正常对照组的RHR(71.0±7.9次/min),有统计学意义(P<0.05);急性心肌梗死组RHR(86.4±7.6次/min)快于不稳定型心绞痛组RHR(80.0±8.3次/min)及稳定型心绞痛组RHR(73.0±8.3次/min),有统计学意义(P<0.05);不稳定型心绞痛组RHR快于稳定型心绞痛组RHR,有统计意义(P<0.05);多支血管狭窄组RHR(82.7±9.7次/min)快于单支血管狭窄组RHR(74.0±8.9次/min),也快于2支血管狭窄组RHR(78.9±9.8次/min),均有统计学意义(P<0.05);冠状动脉狭窄程度≥90%者的RHR(81.7±9.2次/min)快于<90%者(72.4±9.7次/min),有统计学意义(P<0.05)。结论RHR与动脉硬化的发生、CHD的病情与预后有关,静息心率的升高可作为冠心病病情及预后的预测指标。
