Aim: To investigate the precipitating factors that contribute to hospitalization and mortality in postacute heart failure (AHF) hospitalization in the Middle-East region. Methods: We evaluated patient data from the Gulf AHF registry (Gulf CARE), a prospective multicenter study conducted on hospitalized AHF patients in 47 hospitals across seven Middle Eastern Gulf countries in 2012. We performed analysis by adjusting confounders to identify important precipitating factors contributing to rehospitalization and 90- to 120-day follow-up mortality. Results: The mean age of the cohort (n = 5005) was 59.3 ± 14.9 years. Acute coronary syndrome (ACS) (27.2%), nonadherence to diet (19.2%), and infection (14.6%) were the most common precipitating factors identified. After adjusting for confounders, patients with AHF precipitated by infection (hazard ratio [HR], 1.40; 95% confidence interval [CI] 1.10–1.78) and ACS (HR-1.23; 95% CI: 0.99-1.52) at admission showed a higher 90-day mortality. Similarly, AHF precipitated by infection (HR-1.13; 95% CI: 0.93–1.37), and nonadherence to diet and medication (HR-1.12; 95% CI: 0.94–1.34) during hospitalization showed a persistently higher risk of 12-month mortality compared with AHF patients without identified precipitants. Conclusion: Precipitating factors such as ACS, nonadherence to diet, and medication were frequently identified as factors that influenced frequent hospitalization and mortality. Hence, early detection, management, and monitoring of these prognostic factors in-hospital and postdischarge should be prioritized in optimizing the management of HF in the Gulf region.
