心肌梗塞是由于冠状动脉管腔狭窄或持续闭塞缺血缺氧,导致心肌细胞坏死的不可逆的病理过程,心肌收缩性下降,心搏出量降低,心脏收缩舒张功能下降的一组临床症侯群。扩张冠状动脉,增加冠脉血流量的药物疗法是目前临床最常用的方法。本文报告3例心脏梗塞患者应用PTCA术,即经皮用球囊扩张加压的方法直接扩张狭窄的冠状动脉,使冠脉内腔达到解剖学扩张,增加冠脉血流,改善心
Myocardial infarction is due to coronary stenosis or continuous occlusion of ischemia and hypoxia, leading to myocardial cell necrosis irreversible pathological process, decreased myocardial contractility, cardiac output decreased, decreased cardiac systolic and diastolic function of a group of clinical syndromes . Drug therapy to expand the coronary arteries and increase coronary blood flow is currently the most commonly used method in clinical practice. This article reports 3 cases of patients with cardiac infarction PTCA surgery, that is, the method of direct percutaneous balloon dilatation and compression of the dilated coronary artery, the coronary lumen to anatomical expansion, increase coronary blood flow, improve heart
