INTRODUCTION, HF is a burgeoning problem worldwide, with more than 20 million people affected. The overall prevalence of HF in the adult population in developed countries is 2%. HF prevalence follows an exponential pattern, rising with age, and affects 6–10% of people over age 65. Although the relative incidence of HF is lower in women than in men, women constitute at least one-half the cases of HF because of their longer life expectancy. In North America and Europe, the life time risk of developing HF is approximately one in five for a 40-year-old. OBJECTIVE, to assess the predictors of mortality among heart failure patients admitted at KCMC from January-December 2015 METHODOLGY, This study will be a hospital based retrospective cohort study, will involve all hypertensive patients attended KCMC medical outpatient department clinic from January- December 2015. Data collection will be through designed forms on specific objectives files, and then collected data will be entered and analyzed using SPSS statistical package. RESULTS, sample of 79 enrolled with a mean age of 61 S.D=21,anemia patient were 4.96 more likely to die as compared to those who were not anemic with a statistically significant with a p=0.002, O.R=4.96, 95% (0.82 -13.55). Also renal insufficiency patients was 4.8 more likely to die compared to those who were not having renal insufficiency p=0.05 95% OR=4.84.8(1.59-14.46), arrhythmia were 25 more likely to die as compared to those who were not anemic with a statistically significant with a p=0.002, O.R=4.96, 95% (0.82 -13.55. electrolyte imbalance were 12.8 more likely to die as compared to those who were not having electrolyte imbalance O.R= 95% 12.8(4.17 - 39.0). CONCLUSION, In this study all variables anemia, renal insufficiency, arrhythmia and electrolyte imbalance were seen to be independently associated with mortality and on adjusted odds ratio electrolyte imbalance was positively associated with death.
