Why the study?
Most prior Ethiopian studies were single-center, small, retrospective cross-sectional analyses focusing on prevalence and patterns rather than clinical outcomes, predictors, and specific heart failure management.
In Ethiopian tertiary hospitals, heart failure patients experience a high 90-day all-cause mortality (10.2%), which is significantly predicted by hypertension, cardiogenic shock, alcohol consumption, reduced ejection fraction, and the absence of ACEI/ARB therapy.
High 90-day HF mortality with identifiable predictors in Ethiopia; leaves open whether targeted interventions improve outcomes in similar settings.
BACKGROUND: Heart failure is a global pandemic, as it affects approximately 64.34 million people worldwide with a $346.17 billion global economic burden. The prevalence of heart failure has increased from 43.4 to 46.5% in the last 10 years in lower and middle-income countries. Most of the studies conducted in Ethiopia were retrospective cross-sectional, with limited study participants, and conducted in a single setting that commonly addresses the prevalence and pattern of heart failure rather than clinical outcome, associated factors, and specific management in different areas. Hence, this study aimed to assess management, clinical outcomes and their predictors among heart failure patients admitted to tertiary care hospitals in Ethiopia. METHODS: A prospective observational study design was conducted on heart failure patients admitted at two tertiary care hospitals in Ethiopia from September 2020 to May 2021. Using semi-structured questionnaires relevant data were collected from patients' medical records and face-to-face interviewing. Data were analyzed using SPSS version 23.0. A multivariate Cox regression model was performed to identify independent predictors of 90-day all-cause mortality. Variables with P values < 0.05 were considered statistically significant. RESULTS: Out of 283 patients enrolled in this study, 52.3% were male and the mean (± SD) age was 52.4 ± 17.9 years. The most common medications prescribed during hospitalization and discharge were diuretics (98.9% vs 95.6%), angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers (48.8% vs 67.3%), and beta-blockers (46.6% vs 64.7%), respectively. In the present study, the 90-day all-cause mortality was 10.2%. Hypertension (HR = 3.7, 95% CI 1.2-11.6), cardiogenic shock (HR = 8.7, 95% CI 3.2-20.8), alcohol drinking (HR = 2.8, 95% CI 1.1-7.8), absence of angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers (HR = 0.02, 95% CI 0.0-0.2), and reduced ejection fraction (HR = 1.5, 95% CI 1.1-3.8) were predictors of 90-day all-cause mortality. CONCLUSION: High 90-day all-cause mortality was observed among heart failure patients in the present study. In the current study, the majority of heart failure patients were treated with diuretics. Alcohol drinking, hypertension, cardiogenic shock, reduced ejection fraction, and absence of angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers drugs were predictors of poor treatment outcomes for whom restriction of alcohol consumption, early management of hypertension, reduced ejection fraction, cardiogenic shock, and providing angiotensin I converting enzyme inhibitors/angiotensin II receptor blockers drugs for all heart failure patients would be recommended to improve these poor treatment outcomes.
