Résumé

Abstract Abstract Objective: Chronic heart failure is a complex clinical syndrome of functional or structural impairment in the heart. Even though the occurrences of heart failure is increasing in the world, there has been limited researches on the management of chronic heart failure in outpatient, particularly in the study area. Therefore, this studywas amed for the management of outpatients with chronic heart failure. A Retrospective cohort study was conducted from January 1, 2010, to December 30, 2016,on outpatient’s follow-up at Wollo governmental hospitals. A required sample of 487 patients were selected by using a simple random sampling method. Proportional hazard with weibull distribution was modelled since its coefficients more precise than other parametric Cox models. Result: Weibull proportional hazard model result showed that risk factors related to mortality were Age (HR=1.04,p=0.000),Rural in residence (HR=1.74,p=0.003),having poor Nutritional status(HR=3.12, p=0.000),Systolic blood pressure(HR=1.01,p=0.037),having Coronary Artery disease (HR=3.70, p=0.006), having Pneumonia (HR=1.91, p=0.015 and infection with Tuberculosis bacillus (HR=1.87, p=0.000) were found statistically significant. Hence, early identifying and treating of Chronic heart failure and improving a strategies of frequent monitoring and follow up for outpatients is highly recommended .
