心力衰竭除休息、限盐、利尿剂、洋地黄治疗外,近年来随着血管扩张剂及儿茶酚胺类药物的应用,患者住院天数及死亡率虽明显下降,但长期预后仍不乐观。其5年生存率50％,10年生存率低于20％。至于症状持续而对各种治疗反应不佳的难治性心力衰竭,则更使人棘手之极。凡单纯药物治疗无效的患者,人们力图采用人工呼吸机呼气末正压呼吸(PEEP)、体外超滤法(ECUM)、各种机械辅助循环措施,但任何方法亦未能改善绝对性难治性心力衰竭,只能安置永久型人工心脏及心脏移植。
Heart failure in addition to rest, salt, diuretics, digitalis treatment, in recent years with the use of vasodilators and catecholamines, patients with hospital days and mortality decreased significantly, but the long-term prognosis is still not optimistic. The 5-year survival rate of 50%, 10-year survival rate of less than 20%. As for the persistence of symptoms and poor response to a variety of treatment of refractory heart failure, it is even more tricky. Where simple drug therapy is ineffective, people try to use artificial respirator positive end expiratory pressure (PEEP), extracorporeal ultrafiltration (ECUM), a variety of mechanical assisted circulation, but no method to improve the absolute refractory Heart failure can only be placed permanent artificial heart and heart transplant.
