Survival Analysis of Coronary Heart Disease Patient During Revascularization of Coronary Artery in Case of Debre Birehan Compressive Specialized Hospital

Abstract

Introduction: Coronary artery disease (CAD) is one manifestation of ischemic heart disease, which is the leading cause of mortality in the world. Objective: The core objective of this investigation was to analyze Survival Analysis of coronary heart disease of patient during revascularization coronary artery performed. Method: The study was constructed on the data which have 250 patients (subject) with 6 independent variables. The study more explored using survival models such as semi-parametric (Cox PH model) and parametric models (Accelerated Failure Time). Because of some assumptions of cox PH do not well fitted. As we know from theoretical knowledge even if the assumptions are many the parametric models has better acceptance. Basically the data source is already given from Debre Berehan Compressive specialized hospital in registry patient of acute coronary event. Result: According to the results of this study the death of coronary heart patient is affected by factors such as age of patients, revascularization performs, and the day of hospital stays. The hazard ratio for two groups is proportional throughout the days (time) as shown by this paper. The proportion of the death of patient which revascularization performed less than that of did not revascularization of coronary artery performed. And also from AFT model of Weibull the patient of didn’t use revascularization is more accelerate to death then patient use revascularization method.
