CAG and PCI Method
Using Siemens AXIom-Artis DTA from Germany and GE Innova 2000 angiography system from the United States, selective CAG was performed by Judkins method from the femoral artery or radial artery pathways respectively. Diseased vessels were clarified by multi-angle imaging. GE Conduct CAG image analysis was conducted by Centricity AI 1000-GE Mnet (Version 4.2.7.05) and relevant data of interventional therapy were recorded.
