Study type | Interventional |
Acute coronary syndrome (ACS) patients treated with antiplatelet drugs who require coronary artery bypass grafting (CABG) surgery have to wait 5-7 days for the effects of the drugs to wean off. This treatment-devoid period leaves the patient vulnerable, therefore any means to shorten this period could be useful. The present study aims to investigate the possibility of reversing the antiplatelet effects of ticagrelor with the help of fresh donor platelets. Fresh platelets will be added to blood samples of treated patients in varying concentrations at specific timepoints to determine the time and amount of fresh platelets needed to normalize platelet reactivity in the treated samples.

Inclusion Criteria: - Male or female volunteer between 18 and 75 years old. - History of stable (i.e. non-acute) cardiovascular disease or the presence of risk factors for cardiovascular disease (i.e. hypertension, diabetes, hyperlipidemia, high calcium score and abnormal findings on angiography or stress test). Exclusion Criteria: - Conditions associated with hemorrhagic risk, e.g., frequent epistaxis, gastrointestinal ulcer, hemorrhagic vascular lesions, recent surgery. - Allergy or hypersensitivity to aspirin or ticagrelor. - Loss of >400 mL blood or blood donation within past 3 months. - Positive serology for hepatitis B (HBs Ag) or hepatitis C. - History of drug abuse or alcohol abuse. - Positive pregnancy test. - Evidence of unstable or acute cardiovascular disease (e.g., unstable angina, recent myocardial infarction, congestive heart failure). - History of clinically relevant pulmonary, hepatic, gastrointestinal, renal, metabolic, hematologic, neurologic, respiratory or psychiatric disease, bleeding, acute infectious disease or signs of acute illness. |

Primary | P2Y12 Reaction Unit (PRU) | Platelet function normalization using different concentrations (0%, 25%, 50%, and 75% supplementations) of fresh platelet within 48 hours of Ticagrelor Loading dose/last Maintenance dose, assessed using VerifyNow and expressed as P2Y12 Reaction Unit (PRU). The P2Y12 reaction unit (PRU) is an arbitrary unit of measure that represents the amount of platelet aggregation specific to the P2Y12 receptor. | Baseline (pre-treatment), 4, 6, 24 and 48 hours post Loading dose/last Maintenance dose | |
Primary | Platelet Aggregation Using Multiplate Analyzer | Platelet function normalization using different concentrations of fresh platelet within 48 hours of Ticagrelor Loading dose/last Maintenance dose, assessed using Multiplate Aggregometry (ADPtest), results expressed as Area Under Curve (U), where 1 U = 10 AU * min. | Baseline (pre-treatment), 4, 6, 24, and 48 hours post Loading dose/last Maintenance dose |
