IRCT20250730066695N4 IRCT 2025-09-14 Hamedan University of Medical Sciences The effectiveness of pressure point massage on physiological indicators of patients after coronary angiography PPMCA Comparison of the effectiveness of PC6 and ST36 acupressure on cardiac physiological indices in patients after coronary angiography 2025-10-07 anticipated 150 Complete https://irct.ir/trial/86077 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In order to balance the number of samples in each group and prevent bias in allocation, a randomization method with permutation blocks with a block size of 10 will be used. In this method, all possible combinations of five groups including: Intervention group 1 with PC6 pressure point stimulation, Intervention group 2 with ST36 pressure point stimulation, Sham group 1 related to PC6, Sham group 2 related to ST36, and Control group (no intervention) are defined within blocks of 10. Then, the list of combinations is randomly sorted using statistical software, and the final patient allocation table is prepared by an independent statistician, Blinding description: The study is designed as a double-blind study; the interventionist is aware of the group allocation, but the participants, statistical analyst, and care nurses are unaware of the type of intervention received. N/A Coronary angiography. Intervention 1: Intervention group: Intervention group 1 (PC6 point massage): In addition to standard postoperative care, patients in the intervention group will undergo acupressure at the PC6 point. Massage site: The inner surface of the forearm, two fingers above the wrist crease, between the palmaris longus and flexor carpi radialis tendons. Intervention 2: Intervention Group 2 (ST36 point massage): In addition to standard care, patients in this group will receive acupressure at the ST-36 point. The massage site is four finger widths below the lower edge of the kneecap and approximately 2.5 cm outward along the tibia. Intervention 3: Sham group 1 (related to PC6 pressure point): In addition to receiving standard care, patients in this group are subjected to mechanical pressure similar in duration, intensity, and method of application to the PC6 intervention group; the difference is that pressure is applied to a non-therapeutic point with no energy meridian path, approximately 1 to 1.5 centimeters away from the actual PC6 point. Intervention 4: Pseudo Group 2 (related to the ST36 pressure point): In this group, in addition to the usual ward care, patients receive pressure similar in duration (5 minutes), intensity (uniform pressure with the thumb), and method of applying pressure, but at a non-therapeutic point with no therapeutic properties, located 1 to 1.5 centimeters from the actual location of ST36. Intervention 5: Control group: Patients in this group will only receive standard intensive care unit care.
