In-hospital Mortality Factor Analysis Early After Heart Valve Surgery

Objective:To analyze valvular heart disease early postoperative risk factors for hospital mortality, improve surgical cure rate. Methods:From January2010to December2012,488patients with rheumatic valvular heart disease in our department underwent surgery as clinical data; in the early post-operative hospital mortality endpoint for the study, a retrospective analysis of patient age, preoperative cardiac function, valvular disease relationship type and extent of surgical aortic clamping time and perioperative treatment and clinical cure rates and other factors, morbidity and mortality, using univariate and multivariate Logistic regression analysis of the risk of early postoperative mortality factor. Results:488cases of heart valve surgery patients,27cases of early postoperative deaths,5.5%of the total mortality. The main cause of death was low cardiac output syndrome, malignant arrhythmia, multi-organ failure. Univariate analysis showed that:Age≥60years of age, class IV heart unction, combined valve surgery and CABG surgery over the same period, LVEF≤50%,LVEDD≥70mm,CPB time≥120min, aortic clamping time≥60min and the incidence of death after heart valve has correlation (P <0.05). Multivariate Logistic regression analysis:Age≥60years of age, class Ⅳ heart function, valvular surgery earlier CABG surgery, cardiopulmonary bypass time≥120min, LVEF≤50%,LVEDD≥70mm are affected heart valve surgery were independent risk factors for early death. Conclusion:Through the analysis of clinical risk factors to determine the independent prognostic factors were partially affected valve replacement early postoperative death. They can be used for preoperative assessment of risk, identify high-risk surgical patients and guiding their daily clinical work. Reasonable grasp of surgical indications for these factors, choose the timing of surgery, myocardial protection, appropriate surgical approach, these patients can further reduce the mortality and morbidity.
