Type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD) are closely related. T2DM risk equivalent for CVD and it remains the major cause of death in T2DM. Thus, patients with T2DM and CVD disease are at very high-risk of CVD-related mortality. Therefore, more aggressive metabolic and hemodynamic control is required in such patients to improve the prognosis. We recently initiated a cardio-metabolic clinical service at the Heart Hospital, where T2DM patients with existing CVD are simultaneously examined by Cardiologist and Diabetologist for optimal metabolic and hemodynamic control. We would like to start a clinical registry for all patients who attend this clinical service to collect import clinical data about this population. This registry will serve an important source for future clinical research in the field.
