ACC:仅1/10的心衰患者出院时心功能恢复正常

2015-08-19 MedSci 译 MedSci原创

尽管强有力的证据表明,锻炼身体可以提高心脏病患者的生活质量并且减少其就诊率,但是,仅有1/10的心力衰竭患者入院后心脏功能得以恢复。加州大学洛杉矶分校的研究人员从国家数据库中抽取了2005年-2014年超过10万被诊断为心力衰竭的患者进行探究、分析和比较并得出结论,将其发表在the American College of Cardiology。“虽然我们期望心衰患者在在转诊和住院的过程中恢复心功能

“虽然我们期望心衰患者在在转诊和住院的过程中恢复心功能,但是这项研究的结果令我们大吃一惊,”加州大学洛杉矶分校心血管医学和科学研究中心主席Gregg Fonarow如是说道。

每年,美国有870000人被诊断为心力衰竭。心力衰竭简称心衰,是指由于心脏的收缩功能和或舒张功能发生障碍,不能将静脉回心血量充分排出心脏,导致静脉系统血液淤积,动脉系统血液灌注不足,从而引起心脏循环障碍症候群,此种障碍症候群集中表现为肺淤血、腔静脉淤血。心脏无法泵出足够的血液和氧气来支持身体其他器官的情况,总体而言,预计有600万人会出现相应并发症,住院人数超过100万,直接医疗成本超过300亿美元。

多个临床试验表明,若患者接受并参与一个特定的的36周心功能恢复计划,日常规律进行有氧运动训练,则呼吸急促等临床表现可以减轻,并能够更好地参与日常活动,如步行购物和上下楼梯。

2007年HF-ACTION研究具有划时代和里程碑的意义,表明因心衰住院的患者接受运动训练后并可进行正常的日常生活,工作能力提高后,因心衰再次住院和死亡的几率降低。HF-ACTION表明,运动锻炼对于稳定的心衰患者是安全的,而且与较好的临床结果相关,甚至表明患者接受了最佳医疗护理。

在2013,联邦医疗保险和医疗补助服务中心为符合心脏衰竭临床表现的患者提供心功能恢复计划,使更多医保病人得到实惠。

研究人员对全国105619名心力衰竭的住院患者(美国心力衰竭指南的部分研究对象)进行了调查,该研究是美国心脏协会的一部分。他们发现,在他们研究期间,只有10.4%的患者在出院时心功能得以恢复。虽然在近十年的研究中,转诊率上升,但是心功能得以恢复的患者仍然很少。因此,后续研究需要针对提高住院患者心功能着重展开。
