静脉注射潘生丁可以导致正常冠状动脉对狭窄冠脉的“窃血”作用,使狭窄冠状动脉供血区缺血加重,这种缺血可以通过心电图、超声心动图、心肌灌注显像等检查手段显现出来。人的各主要冠脉分支支配特定区域的心肌,相互之间侧支循环较少,据此可以确定病变部位及病变血管。经皮冠状 Intravenous injection of dipyridamole can lead to the “steal” effect of the normal coronary artery on the stenosed coronary artery, which can aggravate the ischemia of the stenotic coronary artery blood supply area. Such ischemia can be revealed by the examination methods of electrocardiogram, echocardiography and myocardial perfusion imaging . The main branch of coronary artery dominate the specific area of ​​the myocardium, collateral circulation between each other less, which can determine the lesion and lesion blood vessels. Percutaneous coronary
