Effectiveness of Atrial Fibrillation as an Independent Predictor of Death and Coronary Events in Patients Having Coronary Angiography

The impact of atrial fibrillation (AF) on future coronary events is uncertain. In particular, the prognostic impact of AF in the clinically important population of coronary patients who undergo angiography is unknown. The aim of this study was to investigate (1) the prevalence of AF, (2) its associa...

description The impact of atrial fibrillation (AF) on future coronary events is uncertain. In particular, the prognostic impact of AF in the clinically important population of coronary patients who undergo angiography is unknown. The aim of this study was to investigate (1) the prevalence of AF, (2) its association with coronary atherosclerosis, and (3) its impact on future coronary events in patients who undergo angiography. Electrocardiograms were evaluated in a consecutive series of 613 patients who underwent coronary angiography. Prospectively, death and cardiovascular events were recorded over 4.0 ± 0.6 years. Among these patients, 37 (6%) at baseline had AF, and 576 (94%) were in sinus rhythm. The presence of AF was associated with a lower prevalence of coronary artery disease and of coronary diameter narrowing ≥50% on baseline angiography. However, prospectively, patients with AF were at a strongly increased risk for all-cause mortality (adjusted hazard ratio 5.15, 95% confidence interval 2.36 to 11.26, p
