The Relationship Between Coronary Artery Disease and Undiagnosed Glucose Metabolism Disorders in Patients who Have Undergone Angiography

ABSTRACT

Purpose: Diabetes mellitus (DM) and coronary artery disease (CAD), seen frequently in the general population, are major causes of morbidity and mortality. DM, controllable through treatment, is one of the most important risk factors for the development of cardiovascular diseases.
Material and Method: Our study included patients who had undiagnosed glucose metabolism disorders and had undergone an angiography under elective conditions. To diagnose the glucose metabolism disorders, these patients were given the oral glucose tolerance test (OGTT) (75 g) within 5-10 days after angiography.
Results: In our study, 24.5% (n=79) of patients had isolated impaired fasting glucose, 9.3% (n=30) had isolated impaired glucose tolerance, 21.1% (n=68) had both impaired fasting glucose and impaired glucose tolerance, and 5% (n=16) had DM. None of these patients knew about their condition beforehand. Only 40.1% (n=129) of patients had normal OGTT results.
Discussion: If patients with suspected CAD found to have blocked arteries after an angiography are screened for DM, glucose metabolism disorders can be diagnosed early. When caught early, the long-term complications can be avoided, resulting in significant savings for health care costs.
