肺血管扩张剂治疗左心疾病(第2组)和肺部疾病(第3组)所致肺动脉高压的随机试验已证明存在潜在危害。然而,这些疗法在实践中被普遍使用。临床试验之外的治疗效果知之甚少。我们的目的是在现实世界的实践中确定血管扩张剂治疗第2/3组肺动脉高压的结果。我们对2006年至2016年期间132,552名符合Medicare资格的退伍军人进行了回顾性队列研究,并进行了二次巢式病例对照研究。我们的主要结局是任何原因导致的死亡或选定的急性器官衰竭的复合终点。在我们的队列分析中,我们使用考克斯比例风险模型和设施特异性随机效应计算了调整后的风险。在我们的病例对照分析中,我们使用逻辑混合效应模型来估计任何过去、最近和累积暴露对我们结果的影响。从我们的队列研究中,3249(2.5%)退伍军人暴露于肺血管扩张剂。在第3组(HR:1.58(95% CI:1.37-1.82))和第2组(HR:1.26(95% CI:1.12-1.41))肺动脉高压患者中,血管扩张剂暴露与我们的主要结局风险增加相关。病例对照研究确定,我们的结果的几率增加了11%,每年的暴露(OR:1.11(95% CI:1.07-1.16))。在临床实践中,使用血管扩张剂治疗第2/3组肺动脉高压与伤害风险增加相关。将试验结果扩展到真实世界环境提供了进一步的证据,以限制在临床试验以外的第2/3组肺动脉高压中使用血管扩张剂。
Randomized trials of pulmonary vasodilators in pulmonary hypertension due to left heart disease (Group 2) and lung disease (Group 3) have demonstrated potential for harm. Yet these therapies are commonly used in practice. Little is known of the effects of treatment outside of clinical trials. We aimed to establish outcomes of vasodilator treatment for Groups 2/3 pulmonary hypertension in real-world practice. We conducted a retrospective cohort study of 132,552 Medicare-eligible Veterans with incident Groups 2/3 pulmonary hypertension between 2006 and 2016, and a secondary nested case–control study. Our primary outcome was a composite of death by any cause or selected acute organ failures. In our cohort analysis, we calculated adjusted risks of time to our outcome using Cox proportional hazards models with facility-specific random effects. In our case–control analysis, we used logistic mixed-effects models to estimate the effect of any past, recent, and cumulative exposure on our outcome. From our cohort study, 3249 (2.5%) Veterans were exposed to pulmonary vasodilators. Exposure to vasodilators was associated with increased risk of our primary outcome, in both Group 3 (HR: 1.58 (95% CI: 1.37–1.82)) and Group 2 (HR: 1.26 (95% CI: 1.12–1.41)) pulmonary hypertension patients. The case–control study determined odds of our outcome increased by 11% per year of exposure (OR: 1.11 (95% CI: 1.07–1.16)). Treating Groups 2/3 pulmonary hypertension with vasodilators in clinical practice is associated with increased risk of harm. This extension of trial findings to a real-world setting offers further evidence to limit use of vasodilators in Groups 2/3 pulmonary hypertension outside of clinical trials.
