Radial artery access is increasingly becoming popular among interventional cardiologists for patients undergoing percutaneous coronary intervention(PCI)/ diagnostic angiography secondary to its low complications rates. However, it is frequently associated with the spasm of the radial artery which can lead to difficulty in catheter manipulation during the procedure and potentially leading to vessel trauma. This vessel trauma can cause activation of coagulation system and formation of clot and subsequently the occlusion of radial artery. In this study the investigators intend to find the association of radial artery spasm with the future development of radial artery occlusion in patients who undergo PCI via radial access.
