Analysis Of Early Death Factors After Valve Replacement In Patients With Valvular Heart Disease Over 60 Years Old

Objective To investigate the risk factors of early death after valvular replacement in patients with valvular heart disease over 60 years of age.Method The patients underwent Cardiac valve replacement(n=178,male102,female 76,aged from 60 to 74)were retrospectively analysised in the Fi-rst Affiliated Hospital of Xinjiang Medical University from April 2012 to April 2016.Preoperative diagnosis by physical examination,laboratory inspe-ction and other comprehensive assessment were confirmed by operation,an-d all heart valve replacements were underwent general anesthesia and cardiopulmonary by pass.Result Severe postoperative complications occurred in 17cases(9.5%)and death in 10 cases(5.61%),Statistical analysis showed that patients(Other nationalities,cardiopulmonary bypass time ? 120 min,aortic cross clamping time ? 60 min,postoperative complications,EF<50% and have a parallel CABG)had a higherdeath rate Co-mpared with other people;Multivariate logistic regression showed that cardiopulmonary bypass time?120 min,EF<50%,having a parallel CABG and complications were significantly independent predictors of opera-tive mortality.Conclusion:Preoperative evaluation according to the clinical chara-cteristics of elderly patients with valvular heart disease,targeted Heart valve replac-ement therapies are contributed to prolong their survival time,elevate survival rate and improve prognosis.
