夜间心绞痛可能是冠状动脉心脏病的表现症状。本文对比研究有和无夜间心绞痛患者的一些特征,如梗塞的部位、原先充血性心力衰竭和心脏增大等,并探讨其病因。方法:冠心监护病房的急性心肌梗塞共174例。急性穿壁性心肌梗塞的诊断系依据典型的心前区疼痛史、明显Q波的形成和典型的血清酶活力演变。有典型病史和与血清酶活力演变而无明显Q波者则诊断为心内膜下心肌梗塞。分析患者入院前一个月的劳力性心绞痛、夜间心绞痛和充血性心力衰竭。结果:164例中104例(63％)在心肌梗塞
Night angina may be a symptom of coronary heart disease. This article compares and analyzes some characteristics of patients with and without nocturnal angina such as infarct sites, previous congestive heart failure and cardiac enlargement, and explores the etiology. Methods: There were 174 cases of acute myocardial infarction in coronary heart care unit. The diagnosis of acute transmural myocardial infarction is based on a typical history of precordial pain, significant Q wave formation, and typical changes in serum enzymatic activity. A typical history and evolution of serum enzyme activity without obvious Q waves were diagnosed as subendocardial myocardial infarction. Analyze patients with exertional angina, nocturnal angina and congestive heart failure one month prior to admission. Results: Of the 164 patients, 104 (63%) had myocardial infarction
