BACKGROUND AND OBJECTIVE: Bundle branch block (BBB) early during acute myocardial infarction (AMI) is often considered high risk for mortality. Little is known about the prevalence of ventricular arrhythmia like ventricular fibrillation in the course of patients with anterior MI and right bundle branch block (RBBB). The aim of this study was to determine the prevalence of VF in patients with anterior AMI and RBBB in Shahid Yahyanejad hospital in Babol.
METHODS: This cross sectional study was performed on 1000 patients’ files that admitted for acute MI in cardiac ward, CCU and emergency room in Shahid Yahyanejad hospital. Patients with Ant. MI and RBBB in electrocardiogram were entered the study. A questionnaire was filled out for every patient included age, sex, extension of MI, risk factors, presence or absence of VF and mortality were gathered and then data were analyzed.
FINDINGS: From 1000 patients with acute MI, 47 had VF with RBBB. Mean age of patients with Ant MI, RBBB and VF was 56±10.34 years old and in patients without VF was 68.4±10.8 years old (p=0.013). Ventricular fibrillation in patients with Ant MI and RBBB was more common in men than women (p=0.047). None of patients with Ant. MI and RBBB with VF had hypertension, but 30.3% of patients with Ant. MI and RBBB without VF had HTN (p= 0.022). Mortality rate in patients with Ant. MI, RBBB and VF was 22.9% and in patients without VF was 6.1%, and it was statistically significant (p= 0.000).
CONCLUSION: The results of this study showed that the prevalence of VF in patients with acute Ant MI and RBBB is more common in men than women and mortality rate of patients with ventricular fibrillation is significantly higher than patients without VF. |
