BACKGROUND: Fibrinolysis remains the primary reperfusion strategy for ST-elevation myocardial infarction (STEMI) in many Asian countries. The outcomes and factors affecting mortality in STEMI fibrinolysis in the Asian population are lacking despite being widely used.
OBJECTIVES: This study aimed to assess the clinical profile of patients and predictors affecting STEMI mortality in an Asian population.
METHODS: This single-center retrospective study analyzed data from STEMI patients who received fibrinolytic therapy from 2016 to 2020 in a tertiary hospital. Logistic regression analysis was performed to identify the significant predictors of the 30-day all-cause mortality, the primary outcome.
RESULTS: A total of 859 patients were included. Their mean age was 53.6 ±12.1 years and they were predominantly male (n=769, 89.4%). The majority of them had anterior involvement STEMI (n = 477, 55.5%) and presented with Killip ≥ II (n = 424, 49.4%). The 30-day all-cause mortality was 12.0% (n = 103). The final model found six predictors for 30-day mortality: age ≥75 (aOR 4.784, p < 0.001), female gender (aOR 2.869, p = 0.001), pre-existing hypertension (aOR 1.623, p = 0.046), anterior myocardial infarction (MI) (aOR 1.947, p < 0.001), Killip class (p < 0.001) and heart rate ≥100 at presentation (aOR 1.823, p = 0.016). Following fibrinolytic therapy, five predictors were found to affect 30-day mortality, i.e. failed fibrinolysis (aOR 2.094, p = 0.041), bleeding events, congestive heart failure (aOR 3.554, p = 0.046), ventricular fibrillation/ tachycardia (aOR 5.920, p < 0.001), and atrial fibrillation/ flutter (aOR 2.968, p = 0.016).
CONCLUSION: Our STEMI patients were younger and more ill at presentation. The risk predictors on 30-day all-cause mortality identified in our Asian population allow the clinicians to better triage and manage STEMI patients.
