- Abstract
Objectives: Unlike "ST-segment elevation myocardial infarction (STEMI)", there is a wide spectrum of ECG changes for Non-STEMI (NSTEMI) patients with varying prognostic implications. Therefore, the purpose of this study was to determine the frequency of ECG changes in patients with positive high-sensitive troponins (hs-cTn) presenting with NSTEMI. Methodology: This Cross sectional study included 282 patients with positive hs-cTn diagnosed with NSTEMI. Standard 12-lead ECG was performed for all the patients. The clinical profile and ECG changes such as ST elevation in aVR, T wave inversion, and ST depression were noted. Results: Out of 282 patients, 68.1% (192) were male, mean age was 58.5 ± 10.6 years, 56.7% (160) were hypertensive, and 39.7% (112) were diabetic. The ECG was normal in 8.2% (23) while, 64.5% (182) had ST-depression, out of which 1.1% (2) had ST-depression of <1mm, 78% (142) had ST-depression of 1-2mm, and remaining 20.9% (38) had ST-depression of >2mm. T-wave inversions were observed in 45.7% (129). ST-elevation of =1 mm in lead aVR was noted in 19.1% (54) patients. Conclusion: A considerable number of NSTEMI patients with positive hs-cTn showed no specific ECG changes. ST-depression followed by T wave inversion and ST-elevation in aVR were the most commonly observed ECG findings in these patients. Considering the prognostic implications and association of these changes with the severity of diseases, prompt decisionmaking regarding invasive management strategy could be helpful in improving the outcomes of these patients.
