Risk of Operative Mortality in Surgery for Coronary Heart Disease (A Multiple Regression Analysis of Perioperative Hemodynamic and Electrocardiographic Data)
Abstract:Using multiple regression analysis, we examined perioperative hemodynamic and electrocardiographic variables as predictors of operative mortality in surgery for coronary heart disease. Data were first analyzed as univariates and, if significantly related to mortality, they were subjected to stepwise logistic multivariate regression analysis. The preoperative predictor variables were: heart rate, ventricular arrhythmia and ST-T shift. The intraoperative predictor variables were: ventricular arrhythmia and ST-T … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
