长期以来,急性心肌梗塞禁用硝酸甘油,因为恐怕它能降低冠脉灌流压力。经动物实验证实,硝酸甘油有利于梗塞区域的缩小;接着一些临床观察亦证实,静注或舌下含服硝酸甘油后,急性心梗患者的SI段偏移明显减轻。但其在急性心肌梗塞中的治疗作用仍未确定。本文观察舌下含服硝酸甘油对胸痛和心肌坏死的心电图征的效果。方法:病例选择:(1)入院四小时内胸痛不减轻;(2)常规ECG在二个导联以上有示心肌损伤的ST段抬高,此外还有血清肌氨酸催化酶、谷—草转氨酶和LDH明显升高,且
For a long time, acute myocardial infarction banned nitroglycerin, because I am afraid it can reduce coronary pressure. After animal experiments confirmed that nitroglycerin is conducive to the reduction of infarct size; followed some clinical observations also confirmed that intravenous or sublingual nitroglycerin, acute myocardial infarction in patients with SI segment migration significantly reduced. However, its therapeutic effect in acute myocardial infarction remains uncertain. This article investigates the effect of sublingual nitroglycerin on electrocardiographic signs of chest pain and myocardial necrosis. Methods: Case selection: (1) chest pain did not decrease within 4 hours of admission; (2) conventional ECG showed ST-segment elevation of myocardial injury above two leads, in addition to serum creatine kinase, Aminotransferase and LDH were significantly elevated, and
