Abstract [en]

OBJECTIVES: This study aimed to determine the incidence of complications of diagnostic coronary angiography that was not followed by percutaneous coronary interventions and to compare differences in complication rates between patients with or without previous coronary artery by-pass surgery. DESIGN: We evaluated major complications due to diagnostic coronary angiography by merging the Swedish Coronary Angiography and Angioplasty Registry (SCAAR), the Swedish Hospital Discharge Registry and the National Population Registry. RESULTS: A total of 1 115 complications were recorded (2.2%). There was a higher incidence of any complications in patients with a previous coronary by-pass surgery in uni-variable analysis (2.7% vs. 2.1%, p=0.003) but not in multi-variable analysis after adjustment for differences in background and procedural factors. Neurological complications were not common (0.20%) but after adjustment for differences in background and procedural factors, the risk of neurological complications was nearly three times higher in patients with a previous CABG compared to patients without previous CABG, odds ratio 2.89 (95% CI 1.68-4.97). CONCLUSION: Neurological complications are significantly more common in patients with previous by-pass surgery. Considering the risk for neurological complications the risk-benefit ratio may be higher when compared with patients without previous by-pass surgery.
