Background: Cardiovascular diseases remain a major global health concern, and coronary care units (CCUs) provide specialized care for patients with acute cardiovascular conditions. Objective: This multicenter cohort study aimed to investigate mortality rates in Turkish CCUs and identify predictors of in-hospital mortality. Study Design: Multicenter, observational cohort study. Methods: Patients admitted to CCUs across Türkiye with cardiovascular diagnoses were included. Demographic, clinical, laboratory, and outcome data were collected. Regression analyses were performed to identify predictors of in-hospital mortality. Results: A total of 3,157 patients were included, and the overall CCU mortality rate was 4.3% (n=137). The median age was 65 years (interquartile range, 56-73), and 66.1% of the patients were male. Hypertension (59.8%) and diabetes mellitus (37.5%) were the most common comorbidities. Non-survivors had significantly higher rates of heart failure and chronic kidney disease and lower ejection fractions than survivors. Age, female sex, lower mean blood pressure (BP), elevated serum creatinine, C-reactive protein, and white blood cell count were independent predictors of in-hospital mortality. Mean BP and serum creatinine were the strongest contributors to mortality prediction. Conclusion: CCU mortality in Türkiye was relatively low. Hemodynamic impairment and renal dysfunction were the primary determinants of in-hospital mortality, highlighting the value of simple clinical parameters for early risk stratification.
