Maladies cardiométaboliques

Description détaillée

Qatar, along with other Gulf Cooperation Council (GCC) countries, experiences one of the highest rates of diabetes, obesity, and cardiovascular risk factors. However, the impact of those risk factors on cardiac diseases, in particular atherosclerotic cardiovascular disease (ASCVD), is not well studied. Further, the incidence of mortality in participants with diabetes and high cardiovascular risk is not known.

We will conduct a prospective, longitudinal, observational cohort that investigates the natural history of cardiometabolic diseases in citizens and long-term residents in Qatar: the Qatar Cardiometabolic Cohort (QCMC). The cohort will examine the prevalence, risk factors, and characterization of cardiometabolic patients, as well as the incidence of mortality and ASCVD events.
