摘要
目的探讨静息心率（RHR）增加与非S-T段抬高急性冠脉综合征（ACS）患者预后的关系.方法非S-T段抬高ACS患者167例,按RHR水平分为：RHR 1组,RHR＜65次/min;RHR 2组,65次/min≤RHR＜70次/min;RHR 3组,70次/min≤RHR＜75次/min;RHR 4组,75次/min≤RHR＜80次/min;RHR 5组,RHR≥80次/min.随访6个月复合心血管事件（包括心脏性死亡、非致命性心肌梗死、非致命性心力衰竭、因反复缺血性心绞痛发作住院）发生率.结果随访167例患者,6个月复合心血管事件发生率为31.1%,RHR 5组随访6个月时反复心绞痛发作住院事件（33.3%）和复合心血管事件（66.7%）均较RHR 1～4组明显增多（P＜0.05及P＜0.01）.结论 RHR增加是非S-T段抬高ACS患者的高危因素.
Objective To investigate the relationship between resting heart rate（RHR） and prognosis of acute coronary syndromes without ST-segment elevation. Methods 167 patients of ACS without ST-segment elevation admitted to hospitals consecutively from Oct. 2001 to Oct. 2004 were divided into five groups according to the levels of RHR[RHR 1 group： RHR〈 65 beats/minute（bpm） ; RHR 2：65≤RHR〈 70bpm; RHR 3 ： 70≤RHR〈 75bpm;RHR 4：75≤RHR〈 80bpm;RHR 5 ：RHR≥80bpm]. The combined cardiovascular events（a combination of cardiac death, nonfatal myocardial infarction, nonfatal heart failure and re-hospital admission due to recurrent isehemia angina） within 6 months were analyzed. Results The incidence of combined cardiovascular events within 6 months among 167 eases was 31.3 %. Compared with RHR 1 - RHR 4 groups, the RHR 5 group showed with higher levels of re-hospital admission due to recurrent isehemla angina and combined cardiovascular events within 6 months（P 〈 0.05 and P 〈 0.01 ）. Conclusion RHR may be one of the high risk factors for patients with ACS without ST-segment elevation.
