Effect of Patent Hemostatic Device (PHD) With Quantitative Pressure on Radial Artery Hemostasis After CAG/PCI

The objective of this clinical trial is to compare the hemostatic effect of 2 hemostatic devices with or without quantitative pressure on radial arteries after coronary angiography (CAG) or percutaneous coronary intervention (PCI). The main questions aims to answer:

* What is the hemostatic effect of the patent hemostatic device with quantitative pressure after percutaneous coronary intervention? * What are the precise hemostatic pressure and hemostatic time of the radial artery after CAG/PCI? Participants will be randomly assigned to the intervention group (IG) and control group (CG). The IG will use patent hemostatic device with quantitative pressure (PHDQP-Band, China) while the CG will use the conventional radial artery hemostatic device (TR-Band, Japan) without pressure monitoring.

The primary outcomes is incidence of 24h radial artery occlusion (24h RAO). Secondary outcomes include time to hemostasis, bleeding, hematoma, 30d radial artery occlusion (30d RAO), pain, hand swelling, numberness, pseudoaneurysm, and radial artery stenosis.
