简要总结
Patients with acute coronary syndrome (ACS) who undergo percutaneous coronary intervention (PCI) are at a higher risk of ischemic complications, even while receiving proper dual antiplatelet therapy. For this reason, identifying high-risk patients and personalizing treatment according to their profile could be a solution towards improving the efficacy and safety of the antiplatelet treatment.
This is a prospective single centre study analyzing correlations and clinical outcomes of patients in relation to biomarkers in acute coronary syndrome. The blood samples were collected from patients admitted to the hospital with a diagnosis of ACS and treated with dual antiplatelet therapy.
The blood samples were collected from each patient within the first 24 hours after the admission for acute coronary syndrome (ACS) and after 72 hours of hospitalization.
详细描述
In this prospective, single-center, observational study, adult patients meeting the inclusion/exclusion criteria were included. Subjects enrolled at the Invasive Cardiology Unit of the 1st Department of Cardiology; Medical University of Warsaw (Poland) were cathegorized into three arms: 1) treated with aspirin and clopidogrel, 2) treated with aspirin and ticagrelor; 3) treated with aspirin and prasugrel. In all three groups subjects first obtained the loading dose of the drug and thereafter they received a fixed daily dose.
Blood samples were collected form each patient at two time-points: during the first 24 hours from hospital admission and after 72 hours following hospital admission. The parameters measured included selected platelet-derived microRNAs prticles, immature platelet fraction (IPF) and platelet microvesicles' comncentration. Platelet reactivity was established using Multiplate® Analyzer (Roche).
