Background: In recent years, radial access has emerged as an alternative for femoral access in coronary arteries angiography. The former has the privilege of shorter hospitalization and fewer side effects, as compared to the latter. Objectives: The present survey aimed to compare the X-ray duration and contrast agent use between radial and femoral access sites. Methods: The present descriptive study was conducted with a convenience sample of 400 patients in 2017 in Bandar Abbas. The sample size was the same in the radial and femoral groups. Information such as age, sex, weight, angiography type and method, X-ray duration and amount of contrast agent was recorded. The collected data were statistically analyzed using SPSS-23. Results: The mean volume of the contrast agent was 44.74 ± 26.31 cc in the radial group and 28.77 ± 20.91 cc in the femoral group. The difference between the two groups was statistically significant (P < 0.001). The mean duration of X-ray was 383.66 ± 329.42 seconds in the radial group and 248.83 ± 225.72 seconds in the femoral group. The difference between the two groups was statistically significant (P < 0.001). Conclusions: Overall, the duration of X-ray and amount of contrast agent used in patients undergoing coronary angiography was higher in radial than in femoral access. This was more evident among patients who had only diagnostic angiography than those who undergone angiography and PCI at the same time.
