休息和运动时发生心绞痛的发病机理可由于冠状动脉痉挛,近年来又引起人们的注意。Prinzmetal心绞痛为休息时自发疼痛并伴有心电图ST段升高,认为是由于冠状动脉痉挛或冠状动脉张力增高所致;这种疼痛可发生于有或无固有的梗阻闭塞的冠状动脉损伤的病人。但是,一些具有典型劳力型心绞痛患者的冠状动脉可正常,可能是由于运动导致冠状动脉张力的改变,而引起冠状动脉血管痉挛、疼痛以及心电图的改变,这种改变常发生于运动的高 Resting and exercise angina pectoris pathogenesis may be due to coronary artery spasm, in recent years has aroused people’s attention. Prinzmetal angina is a spontaneous rest with spontaneous pain accompanied by an increase in the ST segment of the electrocardiogram, which is believed to be due to coronary artery spasms or increased coronary tension; this pain can occur in patients with coronary artery lesions that have or are not obstructed occlusion. However, in some patients with typical angina pectoris, the coronary arteries may be normal, possibly due to changes in the tension of the coronary arteries caused by exercise, which lead to coronary vasospasm, pain and changes in the electrocardiogram, which often occur at high levels of exercise
