Comparison of transradial versus transfemoral diagnostic coronary angiography in terms of oxidative stress: Which option is more physiological?

In this randomized, single-center, clinical study we aimed to compare the oxidative stress response in patients undergoing diagnostic transradial or transfemoral elective coronary angiography. Sixty patients with stable angina pectoris undergoing elective coronary angiography to either transradial (n = 30) or transfemoral (n = 30) approach were included. The levels of plasma total oxidative status (TOS) were measured and compared just before and immediately after the procedure in both groups. The clinical and laboratory findings were compatible between the two groups. Although the levels of plasma total oxidative status after coronary angiography were increased in both groups (TF pTOS 20. +/- :3; 34 +/- 3 vs TR pTOS 18 +/- 2; 23 +/- 4), this was more pronounced in the transfemoral group as compared with the transradial group (Delta pTOS: 11 +/- 4 vs 4 +/- 3, p < 0.001) In correlation analysis, TOS levels and white blood cell counts (r = 0.25, p = 0.042), total cholesterol levels (r = 0.267, p = 0.041), triglyceride levels (r = 0.253, p = 0.049), serum creatinine levels (r = 0.260, p = 0.043) were found to be moderately positively correlated. This study showed that oxidative stress response associated with heart catheterization is more evident in patients undergoing transfemoral coronary angiography versus transradial coronary angiography
