Abstract

Background: Assessment of coronary artery lesion severity plays a crucial role in the prognosis and treatment strategy for patients with acute myocardial infarction. Objective: To determine the severity of coronary artery lesions using the Gensini score and identify associated factors in patients with acute myocardial infarction in Can Tho. Materials and methods: A cross-sectional descriptive study was conducted on 152 patients diagnosed with acute myocardial infarction who underwent coronary angiography. Lesion severity was quantified using the Gensini score. Results: Males accounted for 69.7% of the study population, and the elderly (≥ 60 years) comprised 72.4%. Hypertension was the most common risk factor (77.0%), and the hypertensive group had a significantly higher mean Gensini score compared to the non-hypertensive group (p=0.020). The mean Gensini score in the ST-segment elevation myocardial infarction (STEMI) group was significantly higher than in the non-ST-segment elevation myocardial infarction (NSTEMI) group (53.53 ± 26.74 vs. 27.34 ± 21.09; p<0.001). Multivariate regression analysis identified STEMI as the sole independent prognostic factor associated with an increased Gensini score (p<0.001). Age, gender, BMI, diabetes mellitus, dyslipidemia, and Killip class showed no statistically significant association in the multivariate model. Conclusions: Patients with ST-segment elevation myocardial infarction exhibit a heavier burden of coronary atherosclerosis. The clinical type of infarction is the most significant independent predictor of the Gensini score.
