目的探讨心肌梗死后性行为引起心肌缺血、损伤的危险因素。方法急性心肌梗死(AMI)42例入院后动态测定血清肌酸激酶-MB蛋白(CK-MBmass)计算其心肌梗死量,根据心肌梗死范围大小患者分为A、B组;患者出院后性行为时佩戴动态心电图检测ST-T变化。结果根据血清CK-MBmass动态变化计算其心肌梗死量,其中A组患者平均为32.2 CK-MBmass-g,B组患者平均为21.7CK-MBmass-g,两组对比差异有统计学意义(P<0.01)。出院后患者性行为时计算心电图∑T波、∑ST段改变的面积,其中A组患者平均为5.6mm~2、2.3mm~2;B组患者平均为3.7mm~2、1.2mm~2,两组对比差异有统计学意义(P<0.01)。结论心肌梗死后性行为能否诱发心肌缺血、损伤,取决于心肌梗死量的大小。
Objective To investigate the risk factors of myocardial ischemia and injury caused by sexual behavior after myocardial infarction. Methods Forty-two patients with acute myocardial infarction (AMI) were enrolled in the study. Serum creatine kinase-MB protein (CK-MB) was measured to determine the myocardial infarction volume. Patients were divided into A and B groups according to the size of myocardial infarction. Wearing dynamic electrocardiogram to detect ST-T changes. Results The myocardial infarction volume was calculated according to the dynamic change of serum CK-MBmass, the average of which was 32.2 CK-MBmass-g in group A and 21.7CK-MBmass-g in group B, the difference was statistically significant (P < 0.01). Patients discharged after the calculation of sexual activity ΣT wave ΣST segment changes in the area, including A group of patients with an average of 5.6mm ~ 2,2.3mm ~ 2; B group of patients with an average of 3.7mm ~ 2,1.2mm ~ 2, The difference between the two groups was statistically significant (P <0.01). Conclusions Sexual behavior after myocardial infarction can induce myocardial ischemia and injury, depending on the size of myocardial infarction.
