The Association of Cardiac Troponin I Level on Admission with the Angiographic Severity of Coronary Artery Disease in Acute STEMI Patients

Objective: In this study our main goal is to find out theassociation of cardiac troponin I level on admission with theangiographic severity of coronary artery disease in acuteSTEMI patients.Method: This cross-sectional observational study was done inthe NICVD, Dhaka from October 2010 to September 2011. Atotal of 100 consecutive patients were included. Studypopulations were sub-divided into two groups on the basis ofcTn I level. In group I cTn I level ≥20ng/ml and in group II cTnI level <20ng/ml. 50 patients were included in group I and 50patients were included in group II.Results: Most of the patients presented with more than 4hours chest pain which was 68% vs. 60% patients in group Iand group II respectively. Where mean heart rate was higher ingroup I than group II (83.08.4 vs. 78.210.6). It wasstatistically significant (p=0.01) in student-test. Vessel score 2and 3 together formed the main bulk of the patients (68%) ingroup I, while vessel score 0 and 1 were frequently common ingroup II (80%). In group I there was no patient with vesselscore 0, in group II 12(24%) patients had vessel score 0 (5patients had normal coronaries and 7 patients had insignificantlesions, p-value from Chi square test).Conclusion: From our study we can say that, estimation ofserum cardiac troponin I might facilitate the triage of patientswith acute myocardial infarction by clinicians and moreaggressive approach to promote myocardial reperfusion mightbe warranted in the patients with high cardiac troponin I level.
