The study found that EECP therapy is beneficial for reducing platelet aggregation in patients with coronary heart disease, especially the arachidonic acid-induced platelet aggregation ratio.
Background Resistance to antiplatelet therapy, especially aspirin or clopidogrel, triggers other therapies for patients with coronary heart disease (CHD). Enhanced external counterpulsation (EECP) is a noninvasive, pneumatic technique that provides beneficial effects for patients with CHD. However, the physiological effects of EECP have not been fully studied, and the role of EECP on platelet function remains poorly understood. Methods A total of 168 patients with CHD were finally selected from the Second Xiangya Hospital and randomly assigned to either a control group or EECP group. The control group accepted only standard medical treatment, while the EECP group accepted standard medical treatment and EECP treatment. Blood samples were collected from patients at baseline and after EECP, and platelet aggregation was assessed. Changes in platelet aggregation were compared before and after treatment. Results There was no difference in the basal levels of arachidonic acid (AA) induced platelet maximum aggregation ratio (MAR) between the two groups. The AA-induced platelet MAR was significantly decreased after EECP therapy. The logistic analysis showed that low HDL-C was not favorable for the decrease in platelet aggregation. Conclusion EECP therapy is favorable for lowering platelet aggregation in patients with CHD, especially the AA-induced platelet aggregation ratio.
