NCT02440893
The study goal was to understand the effect of Metformin on Age/Sex/Gene Expression Score (ASGES) or Corus CAD (henceforth "Corus") in pre-diabetic patients who are medication naive. This study provided data to determine if the Corus CAD (ASGES) signature was different in pre-diabetic patients when metformin was newly prescribed and taken.
NCT02405754
This is a retrospective study, designed to be conducted at a single-center in the US. The study will conduct a one-time data abstraction from approximately 500 patient medical charts who received Age/Sex/Gene Expression score (ASGES) also knows as Corus CAD testing, by order of the Principal Investigator. Limited demographic data and patient data pertaining to cardiology referral or advanced diagnostic testing will be collected. All data will be collected anonymously.
NCT03282747
Venous thromboembolism occurs with an incidence of about 1 per 1000 per year in adults . The main consequences are death, recurrence, post-thrombotic syndrome and major bleeding due to anticoagulation. Mortality rates are lower among patients with idiopathic venous thrombosis and higher among those in whom thrombosis occurs in the presence of cancer. The risk increases with the age for unclear reasons. There are also differences in the incidence according to ethnicity; however, data in subjects of European ancestry are scarce. Several studies have documented an association between thrombosis and ABO group. Specifically, non-O blood groups have a higher risk of myocardial infarction, angina, peripheral vascular disease, cerebral ischemia and venous thromboembolism than O. While there are numerous studies carried out in patients who have already shown thromboembolic events, data on the incidence of risk factors in the healthy population are completely inadequate. Understanding the risk factors for venous thrombosis is necessary to maximize the prevention of this disease in individuals and groups of high-risk patients . For this purpose a self-administered questionnaire will be used. Data obtained by blood donors on exposure to risk factors will be used to set up a clinical score to validate in future studies to carry out in patients with VTE.
