Abstract
Background: Evaluation of patients with myocardial infarction in the setting of bundle branch block on electrocardiogram is a new approach in clinical practice. Subjects and research methods: Cross-sectional descriptive study with comparison with a control group. 67 patients with myocardial infarction (28 patients with bundle branch block and 39 patients without bundle branch block) were evaluated clinically, paraclinical, and with coronary angiography. Results: There were no statistically significant differences between the two study groups in terms of age and gender (p>0.05). The rate of patients with heart failure Killip II and above was 42.9%, much higher than the group of patients without bundle branch block (p=0.026). Complications of acute heart failure/cardiogenic shock during hospital stay were 48.4% in the group with bundle branch block, statistically significantly higher than in the group without bundle branch block (p = 0.024). The mean enddiastolic left ventricular diameter was 53.57 ± 6.268 (p<0.01). The median Syntax score was 20.25, higher than that of the myocardial infarction group without bundle branch block (p=0.021). The ST elevation on the electrocardiogram was lower in the right bundle branch block group than in the no right bundle branch block group (p=0.021). The degree of ST segment elevation was positively correlated with Syntax I score (p < 0.01), syntax II (p < 0.05), the degree of coronary artery stenosis (p < 0.05). Conclusion: Myocardial infarction with right bundle branch block had more severe clinical and laboratory signs than myocardial infarction without bundle branch block. Key words: ST elevation, right bundle branch block, coronary artery angiography
