作者认为治疗慢性重型心力衰竭首选的一线药物应满足以下标准:①能快速缓解症状;②能降低死亡率;③能改变其自然病程;④较安全且能被患者所耐受。据此,经大量随机、双盲、安慰剂对照的临床研究证实: 利尿剂是一种缓解症状较快,比较安全地控制心衰的口服药物,但单独使用时尚不能达到长期满意、稳定的治疗目的。洋地黄类强心药物可增加心肌收缩力,减少心衰反复发作的频度,减少利尿剂的用量,增加运动耐受性,且大部份心衰病人能长期耐受此药的治疗,具有其他药物不能取代的效用,是治疗慢性心衰的重要药物之一,但对长期成活率的影响尚不清 The authors believe first-line drugs for the treatment of chronic severe heart failure should meet the following criteria: ① can quickly relieve symptoms; ② reduce mortality; ③ can change its natural history; ④ safer and patient tolerance.
