Objective:
To assess the application status of transradial coronary angiography (TRA) and transradial coronary intervention (TRI) in China in 2007.
Methods:
From Feb 10th to Apr 30th 2008, investigating questionnaires of this study were sent to 450 hospitals in China to collect information on application of percutaneous coronary intervention (PCI) and TRI in these centers.
Results:
One hundred and twelve questionnaires were received. A total of 115 142 coronary angiography (CAG) and 48 379 PCI were performed in these centers including 69 354 TRA (60.24%) and 27 227 TRI (56.28%). A total of 77 488 stents were implanted from 47 160 PCI (1.64 stents per PCI) and 93.98% implanted stents were drug-eluting stent. Total 9290 stents (86.95% drug-eluting stent) were implanted in 7140 primary PCI (1.30 stents per PCI).
Conclusion:
TRA and TRI have become the major approaches of CAG and PCI in China in 2007.
