Variability in Antiplatelet Drugs' Response in Indian Patients Undergoing Percutaneous Coronary Intervention and Outcome Modification by Tailored Antiplatelet Therapy-Juniper Publishers
JUNIPER PUBLISHERS - OPEN ACCESS JOURNAL OF CARDIOLOGY & CARDIOVASCULAR THERAPY Abstract Background: Double or triple antiplatelet therapy is a guideline mandated therapy for patients who undergo Percutaneous Coronary Intervention (PCI). However, there exists inter-individual variability in drug response to the antiplatelet agents leading to recurrent thrombotic events. We sought to study the efficacy and variability of thienopyridines (clopidogrel and prasugrel), ticagrelor and triple antiplatelet therapy in Post-PCI percutaneous coronary intervention (PCI) patients using AggreGuide A-100 platelet aggregometer, a point-of-care-test (POCT) device using laser light scattering technique. Methods: It was a single-centred prospective trial, included 405 patients who underwent PCI. Platelet reactivity was assessed by grading of platelet activity index (PAI) and considered as high on treatment platelet reactivity (HTPR) if PAI >5. Results: Patients on clopido
