NCT03188705
CES1 Carriers in the PAPI Study
This study builds, in part, upon preliminary results generated as part of the Pharmacogenomics Anti-Platelet Intervention (PAPI) Study (NCT00799396). The purpose of this investigation is to assess the impact of genetic variation in the carboxylesterase 1 (CES1) on response to clopidogrel as well as dual antiplatelet therapy (i.e. clopidogrel and aspirin), as assessed by ex vivo platelet aggregometry, in healthy Amish individuals. The investigators hypothesize that participants who carry alleles that modify the activity or expression of CES1 will have altered response to clopidogrel as well as dual antiplatelet therapy.

Dynamics of Platelet Activation in Patients With Ventricular Assist Device (VAD)
Consenting patients with end-stage heart failure that are implanted with/candidates for implant of a short-term/durable mechanical circulatory support device (e.g.: percutaneous microaxial pumps (Impella), extracorporeal membrane oxygenator (ECMO), Ventricular Assist Device (VAD) will be enrolled in the study. Aim of the study is to evaluate the patients' haemostatic and coagulation profile, how it interacts with the support device as well as the effect of antithrombotic drugs. From these data, it will be possible to derive the mechanisms triggering post-implant thromboembolic/hemorrhagic complications and to identify potential therapeutic targets.

Characterization of Exosomes Platelets-released
Extracellular vesicles (EVs) play a key role in cell-to-cell communication. They are small vesicles that contain rich molecular cargo. Recently, they have been proposed as biomarkers for clinical diagnostics. EVs include three classes: small EVs (exosomes), large EVs (microparticles), and apoptotic bodies. Platelet-derived EVs (PEVs) are the most abundant class in human blood and can actively participate in numerous physiological and pathological processes. The information about the role of platelet exosomes in cardiovascular disease and the effect of antiplatelet agents on their release and content is very limited.
