Postoperative myocardial damages after hip fracture repair are frequent and associated with a poor cardiac outcome: a three-hospital study

摘要

SIR—Long-term mortality after hip fracture repair (HFR) isnhigh [1–3] and frequently caused by vascular death [4, 5–7].nSome data have pointed out that the onset of cardiac morbiditynappears early in the course of hip fracture [8–10], butnnone have focused on the correlation between perioperativenischaemic complications and late cardiac outcome. Innvascular surgery patients, studies have shown such a correlationnespecially by using Troponin measurement [11–16].nIn a previous study, we have shown that this phenomenonnexists also after hip surgery [17]. The incidence of a perioperativenmyocardial damage (PMD), as measured by troponinnIc (TnIc) release, was particularly high in the HFR populationn(22%) as were mortality (22%) and the incidence ofnmajor cardiac complications (MCC) (27%). To assess if thisnphenomenon was only due to the local recruitment of theninstitution in which the study was performed, the study wasncompleted to include data from two other academic Frenchninstitutions in which patients were also screened for a followupnperiod of 6 months after surgery.
