【摘要】Background Dual-axis rotational coronary angiography (DARCA) was developed as an innovative adaptation of rotational angiography (RA),but it requires a longer coronary injection compared to standard coronary angiography (SA).As the body of the average Chinese patient is smaller than that of most western patients,with the same contrast injection time,the risk of complications from the contrast agent is increased in this population.The purpose of this study was to assess the clinical safety and efficacy of DARCA in the diagnosis of coronary artery disease (CAD) in the Chinese population by directly comparing it to SA.Methods Two hundred Chinese patients were randomized to either the

SA

group

(n=100)

or

DARCA

group

(n=100).Contrast

utilization,radiation exposure and procedure time were recorded for each modalities.Blood pressure (BP),heart rate (HR) pre and post injection symptoms and any arrhythmias were recorded.Results Compared to the SA group,there was a 42％ reduction in contrast
