Introduction: With increasing burden of Coronary Artery Disease (CAD) and ST-Elevation Myocardial Infarction (STEMI) in India, early risk stratification of patients is as important as making a correct diagnosis. Cardiac Troponin T (cTnT), C-Reactive Protein (CRP) and echocardiographic Regional Wall Motion Abnormalities (RWMA) are used to assess the patients of STEMI at presentation. The short term prognostic importance of these parameters also need to be known.
Aim: To study the prognostic values of admission Cardiac Troponin T (cTnT), CRP and echocardiographic RWMA in patients with acute STEMI.
Materials and Methods: Fifty patients of STEMI were evaluated from January 2017 to July 2017 by Troponin-T (positive >0.18 ng/mL), CRP (positive >3 mg/l) and echocardiography (positive with presence of RWMA) on day one. The patients were divided into three groups: Group 1: patients with all the three parameters positive, Group 2: patients with all three parameters negative, Group 3: patients with one or two parameters positive. The end points observed were heart failure Left Ventricular Ejection Fraction (LV EF) <40%) assessed by echocardiography at day 28, significant ventricular ectopics (>class II by Lown’s classification) and mortality at day 30 in the groups. Chi-square test for equality of proportions was used to analyse the difference in outcome in the groups.
Results: The mean age of patients was 54 years. There were 25 (50%) patients in group 1, 14 (28%) patients in group 2 and 11 (22%) patients in group 3. Twelve (24%) patients had heart failure with 9 (18%) in group 1 and 3 (6%) in group 3 (p<0.05). 9 (18%) patients had significant ventricular ectopics with 8 (16%) patients in group 1 and 1 (2%) patients in group 3 (p<0.05). Mortality was found in 9 (18%) patients with 8 (16%) patients in group 1 and 1 (2%) patients in group 3 (p<0.05).
Conclusion: Acute STEMI with high cTnT, CRP and presence of RWMA on echocardiography at admission need more aggressive management and close follow-up.
