IRCT20230209057372N1 IRCT 2023-10-03 Tehran University of Medical Sciences Comparing radial artery flow-mediated dilation in transient ulnar and brachial artery compression Comparing radial artery flow-mediated dilation in transient ulnar and brachial artery compression 2023-09-28 anticipated 30 Complete https://irct.ir/trial/68634 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Crossover, Purpose: Treatment, Randomization description: Blocks were used for randomization and the participants were divided into 6 blocks of 5 participants. 3 blocks were assigned to group 1; another 3 blocks assigned to group 2, Blinding description: Before starting the study, the participant does not know which group he is in The first group measured the diameter of the radial artery by closing the cuff on the brachial area in the morning and pressing on the ulnar area in the afternoon. The second group measured the diameter of the radial artery by pressing on the ulnar area in the morning and closing the cuff in the brachial area in the afternoon. The radiologist who measures the diameter and area of ​​the radial artery before and after the maneuver does not know the type of maneuver and the time of the study. N/A coronary angiography by radial access. Intervention 1: Intervention group: Ulnar compression will be done for 5 minutes at 8-10 in the morning, and brachial compression will be done at 4-6 in the evening for 5 minutes. Intervention 2: Intervention group: at 8-10 in the morning brachial compression will be performed for 5 minutes, and at 4-6 in the evening, ulnar compression will be performed for 5 minutes. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is There is no further information
