Abstract

BACKGROUND

We evaluated whether early measurement of soluble urokinase plasminogen activator receptor (suPAR) could predict future risk of postoperative complications in initially asymptomatic patients with mild-moderate aortic stenosis (AS) undergoing aortic valve replacement (AVR) surgery.

METHODS

Baseline plasma suPAR levels were available in 411 patients who underwent AVR surgery during follow-up in the Simvastatin and Ezetimibe in Aortic Stenosis (SEAS) study. Cox analyses were used to evaluate suPAR in relation to all-cause mortality and the composite endpoint of postoperative complications (all-cause mortality, congestive heart failure, stroke and renal impairment) occurring in the 30-day postoperative period.

RESULTS

Patients with initially higher levels of suPAR were at increased risk of postoperative mortality with a HR of 3.5 (95% CI 1.4 to 9.0, P=0.008) and postoperative complications with a HR of 2.7 (95% CI 1.5 to 5.1, P=0.002), per doubling in suPAR. After adjusting for the European System for Cardiac Operative Risk Evaluation or Society of Thoracic Surgeons risk score, suPAR remained associated with postoperative mortality with a HR 3.2 (95% CI 1.2 to 8.6, P=0.025) and 2.7 (95% CI 1.0 to 7.8, P=0.061); and postoperative complications with a HR of 2.5 (95% CI 1.3 to 5.0, P=0.007) and 2.4 (95% CI 1.2 to 4.8, P=0.011), respectively.

CONCLUSION

Higher baseline suPAR levels are associated with an increased risk for postoperative complications and mortality in patients with mild-moderate, asymptomatic AS undergoing later AVR surgery. Further validation in other subsets of AS individuals are warranted.

摘要

背景

我们评估了可溶性尿激酶型纤溶酶原激活物受体（suPAR）的早期测量是否能够预测最初无症状的轻中度主动脉瓣狭窄（AS）患者在接受主动脉瓣置换术（AVR）后发生术后并发症的未来风险。

方法

在辛伐他汀和依折麦布治疗主动脉瓣狭窄（SEAS）研究的随访期间，411例接受AVR手术的患者有基线血浆suPAR水平数据。采用Cox分析评估suPAR与全因死亡率以及术后30天内发生的术后并发症复合终点（全因死亡率、充血性心力衰竭、中风和肾功能损害）之间的关系。

结果

初始suPAR水平较高的患者术后死亡风险增加，suPAR每增加一倍，风险比（HR）为3.5（95%置信区间[CI] 1.4至9.0，P = 0.008）；术后并发症风险增加，HR为2.7（95% CI 1.5至5.1，P = 0.002）。在调整欧洲心脏手术风险评估系统或胸外科医师协会风险评分后，suPAR仍与术后死亡率相关，HR分别为3.2（95% CI 1.2至8.6，P = 0.025）和2.7（95% CI 1.0至7.8，P = 0.061）；与术后并发症相关，HR分别为2.5（95% CI 1.3至5.0，P = 0.007）和2.4（95% CI 1.2至4.8，P = 0.011）。
