Objective To evaluate the safety and feasibility of transradial coronary angiography at the outpatient clinic.
Methods From February, 2008 to June, 2008, 100 outpatients who received transradial coronary angiography in Anzhen Hospital were included in this analysis, and 100 inpatients who underwent coronary angiography were selected as control group. Primary endpoints included success rate, percentage of angiographic catheter use with different diameters, adverse events during the procedure (such as death, malignant arrhythmia, acute myocardial infarction, coronary artery spasm, coronary artery dissection, perforation or occlusion, etc.) and after the procedure (such as death, acute myocardial infarction, upper limb haematoma, osteofascial compartment syndrome, radial artery pseudoaneurysm or occlusion, etc.).
Results The success rate (100% vs 100%), procedure duration time (12.5±3.4) min vs (10.8±3.6) min, p =0.517) and exposition time (4.3±1.0) min vs (4.1±1.0) min, p =0.629) were similar between the outpatient and inpatient groups. Radial and coronary artery spasm were the main adverse events during the angiography, and haematoma was the main adverse event after the angiography. There were no significant differences of adverse events between the 2 groups. the total cost of the outpatient group was significantly lower than the inpatient control group (4012±238) yuan vs (5329±371) yuan, p<0.01). Expenditure including chemical tests, medicine, nursing care, Room & Board all decreased significantly.
Conclusion Transradial coronary angiography application at the outpatient clinic was safe and feasible for stable patients, and this procedure could decrease the medical expenditure and shorten the admission time.
