心绞痛是心肌细胞的氧供给与氧需要之间的平衡失调所致。氧供给不足通常是由于冠状血管循环障碍,也可能是由于心肌细胞对氧的利用或氧自血红蛋白的释放等方面的缺陷;影响心肌耗氧量的因素,主要有心肌收缩力、心率及心室壁张力等。增加对心肌氧的输送及降低心肌代谢对氧的需要,是防治心绞痛药物的主要作用途径。现将抗心绞痛药物分别介绍如下: Angina is caused by a dysregulation of the oxygen supply between cardiomyocytes and the need for oxygen. Oxygen supply is usually due to coronary vascular disorders, it may be due to myocardial oxygen utilization or oxyhemoglobin release defects such as oxygen deficiency; myocardial oxygen consumption factors, mainly myocardial contractility, heart rate and ventricular wall Tension and so on. Increase the delivery of myocardial oxygen and reduce myocardial oxygen demand, is the main route of action for the prevention and treatment of angina drugs. Anti-angina drugs are introduced as follows:
