目的用动态心电图(DCG)监测无症状性心肌缺血(SMI)的情况及心痛定与消心痛联合治疗的疗效。方法根据心电监测结果,将患者分为无冠心病史SMI、心肌梗死后SMI、心绞痛伴SMI三组,并给予心痛定及消心痛联合治疗。结果无冠心病史SMI组、心肌梗死后SMI组、心绞痛SMI组的ST段缺血下移次数分别减少76.9%、71.0%、73.8%。结论在治疗冠心病时不应仅满足疼痛的缓解,重点是改善SMI,这对冠心病、冠心病意外的防治有一定作用。DCG监测SMI有着独特的作用。
Objective To monitor the situation of asymptomatic myocardial ischemia (SMI) with ambulatory electrocardiogram (DCG) and the curative effect of combination of nifedipine and antithrombotic therapy. Methods According to the ECG monitoring results, the patients were divided into no history of coronary heart disease (SMI), myocardial infarction (SMI) and angina pectoris (SMI) with three groups. Results The number of ST-segment ischemic attacks in SMI group, myocardial infarction SMI group and angina pectoris group decreased by 76.9%, 71.0%, 73.8% respectively without any history of coronary heart disease. Conclusion In the treatment of coronary heart disease should not only meet the pain relief, the focus is to improve SMI, which coronary heart disease, coronary heart disease prevention and treatment have a role. DCG monitoring SMI has a unique role.
