Study on the Effect of Rehabilitation Ball on the Microcirculation of the Affected Limb after Transradial Coronary Angiography in Patients with Coronary Heart Disease

Objective: To investigate the effect of a rehabilitation ball on the microcirculation of the affected limb after transradial coronary angiography in patients with coronary heart disease. Methods: Thirty-four patients undergoing transradial coronary intervention were selected as study subjects. They were randomly divided into a study group and a control group on the day after coronary intervention using random data selection. Blood flow velocity before coronary intervention, return to the ward after coronary intervention, and at 2, 4, 6, and 8 hours after coronary intervention, as well as changes in blood flow after releasing the pressure device, were compared. Observations included changes in limb swelling before and after coronary intervention, pain levels, anxiety scores, and quality of sleep scores. Results: The study group showed significant improvements in swelling, pain, and sleep quality compared to the control group, with statistically significant differences (P 0.05). Conclusion: Using a rehabilitation ball for wrist exercises in patients undergoing transradial coronary intervention does not significantly affect the peripheral circulation on the side of the coronary intervention but effectively improves limb swelling, reduces pain levels, and promotes patient recovery.
