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. Ischemic heart disease (IHD) comprises 3 entities: stable coronary artery disease (SCAD), unstable angina (UA) and myocardial infarction (MI). Because IHD is associated with an increased risk of adverse clinical events such as heart failure and death, early recognition of IHD is of utmost importance. However, to diagnosis IHD is challenging, as many patients present with atypical symptoms. It is known that women have a different symptom sensation than men. Troponins are the main diagnostic tool for detection of MI. Blood biomarkers for SCAD (typically causing stable angina) and UA, however, are not available. These diagnoses frequently require hospital visits/admissions for time-consuming and costly (non)invasive tests. We show that the plasma extracellular vesicle content can be used as an accurate source for early diagnosis of SCAD and UA.
