INTRODUCTION: The objective of this study is to investigate the possible impact of coronary artery disease (CAD) on clinical outcomes of catheter ablation in patients with atrial fibrillation (AF).
METHODS: Patients with AF who underwent coronary computed tomography and catheter ablation were enrolled. The presence of stenotic severity and plaque, characteristics of coronary arteries, clinical data, and adverse outcomes of catheter ablation were analysed.
RESULTS: A total of 243 patients were enrolled, 100 (41%) patients with CAD. The CHA2DS2-VASc (congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, stroke or transient ischemic attack, vascular disease, age 65-74 years, and sex category) score of AF patients with CAD was significantly (P<0.001) higher than of those without CAD. Presence of stenotic artery and plaques increased significantly with increase of CHA2DS2-VASc score (P<0.05). There was no significant (P=0.342) difference in AF recurrence between patients with and without CAD (30% versus 24%). Age, AF type, duration of AF, heart failure, CHA2DS2-VASc score, left ventricular ejection fraction, and left atrial diameter were significantly (P<0.05) correlated with AF recurrence in univariant analysis. Multivariable analysis revealed that duration of AF (hazard ratio [HR] 1.769), heart failure (HR 1.821), and left atrial diameter (HR 1.487, P=0.022) remained significant independent predictors of AF recurrence. Patients with AF and concomitant CAD were significantly (P=0.030) associated with a worse outcome.
CONCLUSION: CAD concomitant with AF may be associated with a worse clinical outcome even though CAD does not significantly affect the risk of AF recurrence after ablation therapy.
