Abstract
Non‐classical ECG changes in myocardial infarction (MI) are often under recognized, despite their association with adverse clinical outcomes. Identifying these changes is crucial for early diagnosis and optimal management of MI patients. To determine the prevalence of non‐classical ECG changes in MI patients and evaluate their clinical implications. This cross‐sectional study included 60 MI patients admitted to a tertiary care hospital. Detailed demographic, clinical and ECG data were collected. Patients were categorized into classical and non‐classical ECG groups. Clinical outcomes, including heart failure, arrhythmias, hospital stay duration and in‐hospital mortality, were compared. Multi variate analysis was performed to identify predictors of adverse outcomes. Non‐classical ECG changes were observed in 30% of patients. Compared to the classical group, the non‐classical group had higher rates of heart failure (50% vs. 26.2%, p=0.02), arrhythmias (27.8% vs. 9.5%, p=0.04), prolonged hospital stays (38.9% vs. 19.0%, p=0.03) and in‐hospital mortality (16.7% vs. 4.8%, p=0.02). Non‐classical ECG changes were an independent predictor of adverse outcomes (OR 2.5, 95% CI: 1.5‐4.2, p=0.01), along with age >60 years and reduced LVEF. Non‐classical ECG changes are prevalent in MI patients and significantly associated with worse clinical outcomes. Increased awareness and early recognition of these patterns can improve diagnostic accuracy and patient management.
