目的:探讨左房功能 异常对急性心肌梗死的影响。方法:选择129例急性心肌梗死病人根据心电图P波的异常与否分为:左房功能正常组34例,左房功能异常组95例。所有病人均行超声心动图、核素心血池、冠状动脉造影、左室造影等检查,观察12个月再梗及死亡率。结果:左房功能异常组与正常组比较,高血压、糖尿病、前壁心肌梗塞多见(P<0.05),三支病变多见(P<0.01),左室射血分数<40％者多见(P<0.01);12个月时再发心肌梗塞率7.4％。死亡率4.2％,而左房功能正常组无再发心肌梗塞及死亡病例。结论:左房功能异常可能为影响心肌梗塞预后的重要因素。
Objective: To investigate the effect of left atrial dysfunction on acute myocardial infarction. Methods: A total of 129 patients with acute myocardial infarction were divided into three groups based on abnormality of ECG P wave: left atrium function group (n = 34) and left atrium function group (n = 95). All patients underwent echocardiography, radionuclide blood pool, coronary angiography, left ventricular angiography and other tests to observe the 12-month recurrence and mortality. Results: Hypertension, diabetes mellitus and anterior myocardial infarction were more common in the left atrial dysfunction group than in the normal group (P <0.05). Three lesions were more common (P <0.01), left ventricular ejection fraction <40% See (P <0.01); 12 months after the recurrence of myocardial infarction rate of 7.4%. Mortality rate of 4.2%, while normal left atrial function group no recurrence of myocardial infarction and deaths. Conclusion: Left atrial dysfunction may be an important factor affecting the prognosis of myocardial infarction.
