Coronary artery disease is important health issue among the elderly and a leading cause of death, particularly in cases of ST-elevation acute coronary syndrome. Primary percutaneous coronary intervention could reduced the mortality rate, but mortality rate was still high. The objective of this study was to study the factors related to in-hospital mortality of elderly patients presenting with ST-elevation acute coronary syndrome and treated by primary percutaneous coronary intervention in Udonthani hospital.This retrospective descriptive study enrolled 113 patients aged 65 years old and above who presented with ST-elevation acute coronary syndrome and were treated by primary percutaneous coronary intervention between January 1st, 2021, and June 30th, 2022. Collected data from the acute coronary syndrome database and medical records using case record form. The statistics aimed to identify factors related to in-hospital mortality using univariate and multivariate logistic regression analysis statistical significant was 0.05.
Result: Analysis of 113 patients showed that the average age was 74.4 ± 6.6 years old, with all-cause in-hospital mortality was 18.6%, inferior wall STE ACS was 49.6%, Killip 3&4 was 50.5%, Single vessel disease was 51.3%, the average reperfusion time was 55.0 ± 16.5 min. Multivariate analysis revealed acute kidney injury (AOR=6.8, 95%CI 1.2-39.2, p=0.03) as independent factor significantly related to mortality.
Conclusion: The in-hospital mortality among elderly patients in this study was 18.6%. Factor related to in-hospital mortality was acute kidney injury. Identifying at-risk patients and implementing a strong referral system can improve treatment outcomes and reduce complications.
