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.
