Prognostic value of high-sensitive cardiac troponin-T in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention in Erbil cardiac center

Abstract

Background and objectives: Background and objectives: Patients with ST-segment elevation myocardial infarction have higher rates of major adverse cardiovascular events including deaths, and it is recommended that these patients should undergo primary percutaneous coronary interventions. The objective of this study was to determine correlation of high-sensitivity cardiac troponin-T measured on admission with the mortality and major adverse cardiovascular event. Methods: In this study, 167 patients with ST-segment elevation myocardial infarction who underwent primary percutaneous coronary interventions were enrolled. The cut-off value of high-sensitivity cardiac troponin-T measured according to the highest Youden’s index was 528 ng/L. According to this cut-off value, we divided the patients into two groups: those with high-sensitivity cardiac troponin-T ? 528 ng/L (33 patients), and those with high-sensitivity cardiac troponin-T < 528 ng/L (134 patient). Results: The mean age + SD were 57.56 + 11.11 years; the rate of death was 10.8% (n=18) within follow-up period. Incidence of death among patients with higher cardiac troponin-T values (? 528 ng/L) was 27.3%, which was significantly higher than the incidence (6.7%) among those with lower cardiac troponin-T values. After adjusting for the other factors, higher cardiac troponin-T values were associated with higher death rate. Old age and diabetes was found to be significant risk factors for death. While other outcomes and complications were statistically insignificant. Those who suffered cardiovascular death tend to be older, female gender, diabetics, hypertensive, and had diffused coronary arterial disease. Conclusions: Initial cardiac troponin-T on admission is independently associated with the higher risks for 2-year all-cause mortality in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary interventions.
