Prinzmetal首次指述的变异性心绞痛是由冠状动脉痉挛所引起的,此点经冠状动脉造影证实。进而,应用麦角新碱可使心绞痛发作,经超声心动图及核素心肌显像证实在心绞痛发作过程中心肌局部血流减少,并伴有室壁限局性运动失调。本文研究应用麦角新碱诱发心绞痛时,左室功能以及左室壁的限局性运动和血液动力学相
Prinzmetal first refers to the variability of angina pectoris is caused by coronary spasm, this point confirmed by coronary angiography. Furthermore, application of ergonovine can cause angina pectoris, and echocardiographic and radionuclide myocardial imaging confirmed the reduction of local myocardial blood flow during the course of angina pectoris with congestive wall motion disorder. This article studies ergonovine-induced angina pectoris, left ventricular function and left ventricular wall of the limiting exercise and hemodynamic phase
