摘要 ObjectiveCardiovascular 复杂并发症在老新潮的破裂病人贡献手术后的病态和死亡。有限数据关于外科手术前的风险因素哪个预言心血管的功课追随者臀部骨折外科(HFS ) 是可得到的。我们使用了高敏感的 troponin 我(hs-TnI ) 试金和临床的参数在老新潮的破裂 patients.MethodFrom 2014 年 8 月与主要不利心脏的事件(向) 联系了识别外科手术前的风险因素到 2016 年 11 月,有新潮的骨折的 575 个病人在一张回顾的、单个中心的注册表被注册。262 个这些病人的一个总数经历了 HFS 和 hs-TnI 试金。向被定义为手术后的所有原因死亡,心失败(HF ) ,新发作的 atrial 纤维性颤动(AF ) ,心肌的梗塞(MI ) 和发生在 90 天 postoperative.ResultsOf 以内的心血管的再进医院 262 个 HFS 病人,开发的向在 65 的后面的 HFS (24.8%) 。有向的病人是肾的不足,冠的动脉疾病,优先的 HF,低左室的喷射部分和贝它 blockers 的使用的更旧、有的更高的率;支持大脑的 natriuretic 肽(NT-proBNP ) 和更高修订的心脏的风险索引的 hs-TnI 和 N 终端高级。外科手术前的 hs-TnI 6.5 ng/L 与手术后的 HF,新发作的 AF 和向的高风险被联系。在 multivariable 分析,为向的外科手术前的独立预言者是很长时间 > 80 年[调整危险比率(HR ) :1.79, 95% 充满信心的间隔(CI ) :1.03-3.13, P = 0.04 ] ,左室的喷射部分(LVEF )<50%( 调整 HR:3.17, 95% CI:1.47-6.82, P < 0.01 ) 并且 hs-TnI > 6.5 ng/L (调整 HR:3.75, 95% CI:2.09-6.17, P < 0.01 ).ConclusionIn 经历 HFS 的有新潮的骨折的老病人,对 hs-TnI 的一个外科手术前的评价可以帮助心血管的复杂并发症的风险精炼。 Objective Cardiovascular complications contribute to postoperative morbidity and mortality in elderly hip fracture patients. Limited data are available regarding which preoperative risk factors predict cardiovascular course following hip fracture surgery (HFS). We used high sensitive troponin I (hs-TnI) assays and clinical parameters to identify preoperative risk factors associated with major adverse cardiac events (MACE) in elderly hip frac^u'e patients. Method From August 2014 to November 2016, 575 patients with hip fracture were enrolled in a retrospective, single-center registry. A total of 262 of these patients underwent HFS and hs-TnI assays. MACE was defined as postoperative all-cause deaths, heart failure (HF), new-onset atrial fibrillation (AF), myocardial infarction (MI) and cardiovascular re-hospitalization that occurred within 90 days postoperative. Results Of 262 HFS patients, MACE developed following HFS in 65 (24.8%). Patients with MACE were older and had higher rates of renal insufficiency, coronary artery disease, prior HF, low left ventricular ejection fraction and use of beta blockers; higher levels of hs-Tnl and N-terminal pro-brain natriuretic peptide (NT-proBNP) and higher revised cardiac risk index. A preoperative hs-TnI≥ 6.5 ng/L was associated with high risk of postoperative HF, new-onset AF and MACE. In multivariable analysis, pre-operative independent predictors for MACE were age 〉 80 years [adjusted hazard ratio (HR): 1.79, 95% confident interval (CI): 1.03-3.13, P = 0.04], left ventricular ejection fraction (LVEF) 〈 50% (adjusted HR: 3.17, 95% CI: 1.47-5.82, P 〈 0.01) and hs-TnI 〉 6.5 ng/L (adjusted HR: 3.75, 95% CI: 2.09~5.17, P 〈 0.01). Conclusion In elderly patients with hip fracture who undergo HFS, a preoperative assessment of hs-TnI may help the risk refinement of cardiovascular complications.
