Key result
Three-vessel disease (OR 2.582; 95% CI 1.165-5.720; p=0.019) and history of CABG were independent predictors of ventricular fibrillation during coronary angiography.

Chen et al. (2009) conducted an observational in Ventricular fibrillation during diagnostic coronary angiography (n=22,254). Diagnostic coronary angiography was evaluated on Ventricular fibrillation occurrence (predicted by three-vessel disease) (OR 2.582, 95% CI 1.165-5.720, p=0.019). Three-vessel disease (OR 2.582; 95% CI 1.165-5.720; p=0.019) and history of CABG were independent predictors of ventricular fibrillation during coronary angiography.
