- Abstract
Objective: To compare the short-term outcomes of patients with Occlusive Myocardial Infarction and Non-occlusive Myocardial Infarction in the context of non-ST Elevation Myocardial Infarction. Study Design: Analytical cross-sectional study. Place and Duration of Study: Armed Forces Institute of Cardiology/National Institute of Heart Diseases, Rawalpindi Pakistan; from Jul to Nov 2023. Methodology: One hundred and ninety four patients aged 20 to 75 years with NSTEMI were consecutively enrolled. Patients were classified into OMI and NOMI groups using angiographic, laboratory tests and electrocardiographic findings. Short-term outcomes such as stroke, heart failure, recurrent myocardial infarction, and mortality were recorded. The comparative analysis assessed differences in baseline characteristics and clinical endpoints between Occlusive Myocardial Infarction and Non-occlusive Myocardial Infarction patients. Chi square test was applied to compare the categorical variables among study groups and p-value <0.05 was considered as statistically significant. Results: Among 194 patients, there were 71(36.6%) patients with Occlusive Myocardial Infarction and 123(63.4%) with Non-occlusive Myocardial Infarction and mean age was 60.68 ±12.97 years. Majority of the patients presented with Triple Vessel Coronary Artery Disease 89(45.9%), followed by Single and Double Vessel Coronary Artery Disease [60(30.9%); 45(23.2%)] respectively. Short-term outcomes included heart failure 50(25.8%), stroke 4(2.1%), recurrent MI 8(4.1%), and death 7(3.6%). However, the difference was not significant among study groups (p>0.05). In OMI group, diabetes mellitus, hypertension, hyperlipidemia and Coronary Artery Disease were found significantly associated with morbidity and mortality (p<0.05), while none of the variables were significantly associated with morbidity and mortality in NOMI group (p>0.05). Conclusion: The study emphasizes tailored management strategies for NSTEMI patients, specifically, the disconnect between baseline risk of the two groups and the timely utility of invasive strategy can help improve prognosis.
