BackgroundCardiology guidelines identify the low-risk response during stress echocardiography as the absence of regional wall motion abnormalities.MethodsFrom 1983 to 2016, we enrolled 5817 patients (age 63±12 years; 2830 males) with suspected coronary artery disease, normal regional, and global left ventricular function at rest and during stress (exercise in 692, dipyridamole in 4291, and dobutamine in 834). Based on timing of enrollment, 4 groups were identified in chronological order of recruitment: years 1983 to 1989, group 1 (n=211); years 1990 to 1999, group 2 (n=1491); years 2000 to 2009, group 3 (n=3285); and years 2010 to 2016, group 4 (n=830).ResultsThere were 240 (4%) events (119 deaths and 121 infarctions) in the follow-up. At 1-year follow-up, the event rate was 0.5% (95% CI, 0.05–0.95), 1.5% (95% CI, −1.18 to 1.82), 1.9% (95% CI, 1.63–2.17), and 1.7% (95% CI, 1.01–2.39; χ2, 9.0; P=0.03) in groups 1 to 4, respectively. At multivariable Cox analysis, independent predictors of future events were age (hazard ratio (HR), 1.05; 95% CI, 1.04–1.07; P<0.0001), male sex (HR, 1.57; 95% CI, 1.20–2.04; P=0.001), diabetes mellitus (HR, 1.78; 95% CI, 1.34–2.37; P<0.0001), smoking habit (HR, 1.40; 95% CI, 1.05–1.85; P=0.02), and ongoing anti-ischemic therapy (HR, 1.50; 95% CI, 1.15–1.97; P=0.003)ConclusionsOver the past 3 decades, we observed a progressive decline in the prognostic value of a negative test based on regional wall motion abnormalities, likely reflecting both an increase in risk in patients, as well as a potential decrease in test performance due to concomitant anti-ischemic therapy.

由于研究对象群体的参考资料不断变化,基于静息左心室功能正常的患者,基于区域壁运动异常的负应力超声心动图的明显下降的预后价值

方法从1983年至2016年,我们纳入了5817例可疑冠状动脉疾病,正常区域性和全球性疾病的患者,共计5817例(年龄63±12岁; 2830例男性)休息和压力时左心室功能(锻炼692例,双嘧达莫在4291例,多巴酚丁胺在834例)。根据招募时间,按招募时间顺序确定了4个组:1983年至1989年,第1组(n = 211);第1组(n = 211)。1990年至1999年,第2组(n = 1491);2000年至2009年,第3组(n = 3285);以及2010年至2016年的第4组(n = 830)。结果随访中发生240例(4%)事件(119例死亡和121例梗死)。在1年的随访中,事件发生率分别为0.5%(95%CI,0.05-0.95),1.5%(95%CI,-1.18至1.82),1.9%(95%CI,1)。2,9.0; P = 0.03)分别在第1至第4组中。在多变量Cox分析中,未来事件的独立预测因子是年龄(危险比(HR),1.05; 95%CI,1.04–1.07;P <0.0001),男性(HR,1.57; 95%CI,1.20–2.04;P = 0.001),糖尿病(HR,1.78; 95%CI,1.34–2.37; P <0.0001),吸烟习惯(HR,1.40; 95%CI,1.05-1.85; P = 0.02)和正在进行的抗缺血治疗(HR,1.50; 95%CI,1.15-1.97;P= 0.003)结论在过去的30年中,我们观察到了基于局部壁运动异常的阴性测试的预后价值逐渐下降,这可能反映了患者风险的增加以及由于以下原因导致的测试性能的潜在下降:伴随抗缺血治疗。
