活性外周血管舒张剂在临床上的运用,是治疗心衰的新方向,而且对心肌无直接影响。这类药物有:三硝酸甘油脂,硝普钠及肾上腺α-受体。作者认为,影响静脉张力的血管舒张剂能降低血液流向心脏,降低“前负荷”和肺充血,改变动脉的紧张度,减轻心脏废弃物的阻力,注射血管舒张剂还可降低心肌耗氧量,改善血液供给,并使心肌梗塞患者之心脏局
The clinical application of active peripheral vasodilators is a new direction for the treatment of heart failure, and it has no direct effect on myocardium. These drugs are: trinitrate, sodium nitroprusside and adrenal α-receptor. The authors believe that vasodilators that affect venous tension reduce blood flow to the heart, reduce “preload” and pulmonary congestion, alter arterial tone, and reduce resistance to heart wastes. Injection of vasodilators may also reduce myocardial oxygen consumption, Improve blood supply, and make heart surgery in patients with myocardial infarction
