Abstract
BACKGROUND: The prevalence and predictors of in-hospital mortality in the unselected patients with ST-segment elevation myocardial infarction (STEMI) after reperfusion therapy with fibrinolytic or primary percutaneous coronary intervention (PCI) in developing country have not well established. METHODS: We conducted a retrospective cohort study design. All admission records of acute ST elevation myocardial infarction at Suratthani Hospital between October 2015 and September 2017. RESULTS: The finding between October 2015 and September 2017, a total of 431 patients received reperfusion therapy and were included in the present study. Majority of the patient were male (80.5%), almost half of the population had anterior wall MI, 32 patients died (7.4%), and 399 survived during the index hospitalization. The prevalence of chronic kidney disease, anterior wall MI, cardiogenic shock and cardiac arrest in non-survived group was higher than the survived group. Echocardiogram was performed in 299 patient (69.4%) and the median left ventricular ejection fraction (LVEF) in overall population was 51%. After adjustment for baseline variables, LVEF (aOR 0.91, 95% CI, 0.83-0.98, P=0.02) and cardiac arrest at presentation (aOR 22, 95% CI, 1.22-410.05, P=0.036) were independently associated with in-hospital mortality. CONCLUSIONS: LVEF and cardiac arrest at presentation were independently associated with in-hospital mortality in STEMI patients receiving reperfusion therapy either fibrinolytic therapy or primary PCI. 2020 Cardiovascular Diagnosis and Therapy.
