Cardiovascular Disease (CVD) is with the cardiovascular events of Ischemic Heart Disease and Stroke, the number 1 and 2 cause of death in the world and expect to increase especially in Asia. We use plasma extracellular vesicle (EV) protein content of vesicles from plasma subfractions on plasma of stroke and periferal artery disease(PAD) patients, patients after carotid atherectomy (CEA) and patients suspected for chronic coronary syndrome (CCS). Using 25 ul of plasma, we developed an automated 96-well based protocol using sequential precipitation. Using samples of the AtheroExpress, the largest ongoing CEA biobank we try to early detect the risk of a second Major Adverse Cardiovascular Event (MACE: myocardial infarction, stroke or cardiovascular death) in PAD and CEA patients. Identification of such high risk patients is very important for possible (expensive) add-on pharmaceutical therapy or the decision to operate or not. Sequential procipitation for EV isolation is also used for the diagnosis of CCS.
