近年来,已明确血小板与动静脉血管阻塞、平滑肌肥大有关,可能还与粥样硬化的产生有关。若血小板功能改变关系到冠脉疾病的发生并由此影响心血管疾病的死亡率和发病率,那么,冠心病人使用抗血小板药物应是合理的。动物实验的冠脉狭窄引起的心肌缺血模型中,血小板短时间内就可在冠状血管中凝集,使微循环闭塞,血流减少,导致心肌损伤。已
In recent years, it has been clearly platelet and arteriovenous occlusion, smooth muscle hypertrophy, may also be related to the production of atherosclerosis. If the change of platelet function is related to the occurrence of coronary artery disease and thus the mortality and morbidity of cardiovascular diseases, it should be reasonable to use antiplatelet drugs in patients with coronary heart disease. Animal models of coronary artery stenosis caused by myocardial ischemia, platelets can be a short period of agglutination in the coronary vessels, the microcirculation occlusion, blood flow, leading to myocardial injury.
