Symptomatic bradyarrhythmia occurs most often in aged patients. Most of these patients have multiple coronary risk factors and present with angina-like symptoms. The coexistence of CAD not only has major effects on their prognosis but also influences the long-term care. This study was designed to evaluate the incidence of coexistent CAD in patients with symptomatic bradyarrhythmias and its relationship to conventional coronary risk factors in our population. From May 2004 to June 2005, we prospectively studied all consecutive patients admitted to our institution for symptomatic bradyarrhythmias requiring permanent pacemaker implantation. Coronary angiographies were performed non-selectively at the same session of pacemaker implantation. Based on the presence or absence of CAD, patients were divided into two groups for analysis. Multivariate logistic regression analysis was performed to determine independent predictors of CAD including sex, age, diabetes mellitus (DM), hypertension, hypercholesterolemia, and smoking. The oddsratio (OR) was determined. In our patients with symptomatic bradyarrhythmias requiring permanent cardiac pacing, the incidence of CAD was 31 % as determined by coronary angiography (CAG). Male sex, hypertension, hypercholesterolemia and diabetes mellitus were the significant predictors for CAD in these patients. The Av nodal artery was commonly involved in patients with coexistent CAD and symptomatic bradyarrhythmias due to AV block. In conclusion, coexistent CAD was noted in a significant number (31% ) of our patients receiving permanent pacemaker implantation for symptomatic bradyarrhythmia. Among the conventional coronary risk factors, male sex, hypertension, DM and hypercholesterolemia were the significant predictors and may act as important markers for the judgment of further coronary artery evaluation. The AV nodal artery was commonly involved among patients with bradyarrhythmia due to AV block and coexistent CAD.
