Abstract

It is unknown how much different are the clinical outcomes between asymptomatic and symptomatic patients with severe aortic stenosis (AS). In the CURRENT AS registry enrolling 3,815 consecutive patients with severe AS, we compared the long-term outcomes between 1808 asymptomatic and 1215 symptomatic patients (exertional dyspnea: N = 813, syncope: N = 136, and angina: N = 266) without heart failure (HF) hospitalization. Symptomatic patients had greater AS severity, and more depressed left ventricular function than asymptomatic patients without much difference in other baseline characteristics. During a median follow-up of 3.2 years, aortic valve replacement (AVR) was performed in 62% of symptomatic patients, and 38% of asymptomatic patients. The cumulative 5-year incidences for the primary outcome measure (a composite of aortic valve-related death or HF hospitalization) was higher in symptomatic patients than in asymptomatic patients (32.3% versus 27.6%, P < 0.001). After adjusting for AVR and other variables, the greater risk of symptomatic relative to asymptomatic patients for the primary outcome measure was significant (hazard ratio 1.64, 95% confidence interval 1.41-1.96, P < 0.001). In conclusions, the excess risk of symptomatic relative to asymptomatic patients with severe AS for the aortic valve-related event was significant. However, the prevalence of AVR in symptomatic patients was not optimal.

摘要

目前尚不清楚无症状和有症状的重度主动脉瓣狭窄(AS)患者的临床结局有何不同。在 CURRENT AS 注册研究中,共纳入了 3815 例重度 AS 连续患者,我们比较了 1808 例无症状和 1215 例有症状患者(劳力性呼吸困难:N=813,晕厥:N=136,心绞痛:N=266)的长期结局,这些患者均无心力衰竭(HF)住院史。有症状的患者 AS 严重程度更高,左心室功能较无症状患者更差,但其他基线特征差异不大。在中位随访 3.2 年期间,有症状患者中有 62%接受了主动脉瓣置换术(AVR),而无症状患者中有 38%接受了该手术。主要终点(主动脉瓣相关死亡或 HF 住院的复合终点)的 5 年累积发生率在有症状患者中高于无症状患者(32.3%比 27.6%,P<0.001)。在校正 AVR 和其他变量后,有症状患者相对于无症状患者发生主要终点事件的风险显著增加(风险比 1.64,95%置信区间 1.41-1.96,P<0.001)。总之,与无症状患者相比,有症状的重度 AS 患者发生主动脉瓣相关事件的风险更高。然而,有症状患者中 AVR 的比例并不理想。
