Abstract
Objectiye: To explore the risk iactors for in-hospi1almortali1y of pathents with severe valvular heart disease after surgery, and to offer the basis in Older to prevent if s occurrence. M etiiods: Clinical date of235 cases with severe valvular heart disease were analyzed retrospectively. Divided into 1wo groups accord ing to whether or not death after surgery, preoperative and postoperative date were evaluated by uni-variate analysis andmultivariate logistic regression analysis. Results; Thirty- 1wo cases died during the hos-piteland the tetelity rate wasl3.6%. Low cardiac output, multiple organ iailure and malignant arrhythnia were the most frequent cause of death. Results in logistic regression method, age 3=65 years, history of valve≥l5 years, New York HeartAssociatbi( NYHA) class IV, card fothoracic rations 0.7, left ventricular ejection fractbn( LVEF) ≤0.4, concanitent coronary artery bypass graft( CABG), and acHosis in postopeF-ative24 hours were the independent risk iactors for in-hospitelmortality after surgery. Conclusion: The mortality of severe valvular heart disease after surgery was high and the pathentsmay suffer fron many can-plications The course of disease, degree of basic pathological change of heart, and perioperative treament can affect the incidence of postoperative death; early surgery, a positive preoperative preparation, shortening cardfopumonary bypass tine, and maintaining acid-base balance may be the most effective preventive method of death occurred early after card fovascular surgery.关键词
