Vascular closure device, hemostatic bandage and manual compression can achieve hemostasis after angiographic examination. These three methods of hemostasis changed the rate of hemostasis, early ambulation, hematoma , hemostasis failure rate, and expense. Therefore, shared decision making (SDM) is necessary to aid patients to choose hemostasis.The investigators have developed a decision aids (DA) and planned a randomized controlled trial (RCT) to evaluate its impact on angiographic patients. The measurements include a battery of interview-based questionnaires and evaluations of decision conflicts. The investigators expect the DAs would benefit the intervention group in the aspects of knowledge, communication and choice conflicts.during and after thier Hemostasis procedure.
