目的观察不同静息心率(RHR)对女性急性心肌梗死(AMI)患者预后的影响。方法回顾分析2004年2月至2010年2月我院收住的女性急性心肌梗死234例,根据住院期间平均静息心率随机分为3组,分别为平均RHR在55～64次/min、65～79次/min、80次/min以上,按心梗常规治疗,观察1月内心力衰竭、恶性心律失常、猝死、心绞痛发作、再梗等心脏不良事件发生率。结果 RHR在55～64次/分心脏不良事件发生率最低。结论女性AMI应严格控制静息心率。
Objective To observe the effect of different resting heart rate (RHR) on the prognosis of female patients with acute myocardial infarction (AMI). Methods A retrospective analysis of 234 women admitted to our hospital from February 2004 to February 2010 were randomly divided into 3 groups according to the average resting heart rate during hospitalization: mean RHR at 55-64 beats / min, 65 ~ 79 beats / min and 80 beats / min or more. According to the conventional treatment of myocardial infarction, the incidence of adverse cardiac events such as heart failure, malignant arrhythmia, sudden death, angina pectoris and restenosis within 1 month were observed. Results RHR 55 to 64 beats per minute, the lowest incidence of cardiac adverse events. Conclusion Female AMI should strictly control resting heart rate.
