Effect of ticagrelor and clopidogrel dual antiplatelet therapy on MPVLR, MAADP, and AA inhibition rate in acute coronary syndrome patients after percutaneous coronary intervention

Effect of ticagrelor and clopidogrel dual antiplatelet therapy on MPVLR, MAADP, and AA inhibition rate in acute coronary syndrome patients after percutaneous coronary intervention  Medicine(Baltimore). 2023 Sep 15;102(37):e34974.   Abstract Objective: To explore the effects of ticagrelor and clopidogrel dual antiplatelet therapy on the mean platelet volume-to-lymphocyte ratio (MPVLR), maximum amplitude of adenosine diphosphate-induced platelet-fibrin clots (MAADP), and arachidonic acid (AA) inhibition rates in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).   Methods: A total of 120 patients with ACS undergoing elective PCI in our hospital between March 2020 and November 2021 were recruited. Patients were divided into 2 groups using the random number table method, with 60 patients in each group. The control group received clopidogrel + aspirin dual antiplatelet therapy, while the study group received ticagrelor + aspirin dual antiplatelet therapy. MPVLR, MAADP, and AA inhibition rates were compared between the 2 groups. Platelet activation indices, platelet micro PNA-223, and platelet gelsolin levels were measured before and 4 weeks after PCI. Changes in cardiac function indices, bleeding rates, and major adverse cardiovascular events (MACE) were compared between groups.   Results: The MAADP score of the study group was lower than that of the control group 3 days after surgery (P < .05). Compared with before surgery, CD62p, CD63, miR-223, PAC-1, platelet membrane glycoprotein IIb/IIIa complex, and gelsolin levels markedly decreased in both groups 4 weeks after surgery (P < .05). The platelet activation index and platelet miR-223 and gelsolin levels were significantly lower in the study group than in the control group 4 weeks after surgery (P < .05). The overall platelet inhibition effect was significantly better in the study group than in the control group (P < .05). Compared with before surgery, the left ventricular ejection fraction and stroke volume were significantly increased, and the left ventricular end-diastolic volume and left ventricular end-diastolic diameter significantly decreased in both groups 4 weeks after surgery (P < .05). No significant differences were found between the 2 groups in terms of the incidence of bleeding events or MACE (P > .05).   Conclusion: Ticagrelor is more effective than clopidogrel for platelet inhibition after PCI in patients with ACS and is worthy of clinical recommendation.
