中低强度体育锻炼对急性冠脉综合征预后的影响

The Influence of Mild to Moderate Exercise on Prognosis of Patients with ACS

目的观察中低强度体育锻炼对急性冠脉综合症(ACS)预后的影响.方法将临床确诊为ACS的308例患者分为坚持进行中低强度体育锻炼组与不进行体育锻炼的对照组随访2 a,比较2组的心血管事件发生率及了解、观察中低强度体育锻炼对ACS患者心率变异性的影响.结果 ACS坚持进行中低强度体育锻炼组患者心绞痛、急性ST段抬高心肌梗死、急性非ST段抬高心肌梗死、心力衰竭、短阵室性心动过速、心室颤动、心脏性猝死的发生率分别为:33.1%,5.2%,9.1%,46.8%,3.9%,3.2%,2.6%.ACS坚持进行中低强度体育锻炼患者心血管事件的发生率降低,ACS坚持进行中低强度体育锻炼患者时域指标,高频功率均高于对照组,极低频功率,低频功率低于对照组.结论中低强度体育锻炼可能改善ACS患者预后.

Objective To investigate the influence of mild to moderate exercise on prognosis of patients with ACS.Methods The 308 ACS patients were divided into mild to moderate exercise group（n=154）and lacking exercise group（n=154）.All patients were followed up for 2 years.The incidence of short-term cardiovascular events were compared between two groups,and the the influence of mild to moderate exercise on HRV variation in ACS patients was analyzed.Results The incidence of congina cordis,STEMI,NSTEMI,CHF,ventricular tarchycardia,ventricular fibrillation and sudden death in the near future were 33.1%,5.2%,9.1%,46.8%,3.9%,3.2% and 2.6%,respectively Mild to moderate exercise decreased the incidence of cardiovascular events in ACS patients respectively.The SDNN,SDANN,SDNN index,RMSSD,PNN50 and HF were lower and VLF,LF were higher in the exercise group than those in non-exercise group.Conclusion Mild to moderate physical exercise may change the prognosis of patients with ACS
