急性心肌梗塞后低血压合并严重左心衰竭通常预后不良,常提示广泛性心肌坏死和预示心原性休克即将来临。增加左心室泵功能和减轻肺充血以恢复正常灌注压,是迫在眉睫的。 本文评价了数例广泛心肌梗塞后并发进行性左心衰竭的病人,同时静滴硝酸甘油和多巴酚丁胺的疗效。
Hypotension after acute myocardial infarction with severe left ventricular failure usually has a poor prognosis, often suggestive of extensive myocardial necrosis and predicts the onset of cardiogenic shock. It is imminent to increase left ventricular pump function and reduce pulmonary congestion to restore normal perfusion pressure. This article evaluates the efficacy of nitroglycerin and dobutamine in patients with progressive left heart failure following several extensive myocardial infarctions.
