Background: Patients with diabetes mellitus (DM) and coronary artery disease (CAD) represent a high-risk population, where comorbidities are common and the progression of coronary heart disease is relatively rapid and extensive. The present survey, conducted nationwide in a Eurozone country, Greece, with a properly organized national health system, aimed to record specific data from a significant number of patients with diabetes and documented stable CAD (SCAD).
Methods and results: We conducted our survey across the country, in private and public primary, secondary, and tertiary care centers. A total of 1900 patients aged 71 ± 10 years old who suffered from both DM and chronic coronary syndromes were registered. Of the patients registered, 574 (30.24%) were women. It was found that 506 (26.6%) of the 1900 surveyed patients showed typical angina symptoms, while another 560 (29.5%) patients had developed angina-equivalent symptoms according to their history. Additionally, 324 (17%) patients had atypical symptoms that could not easily be attributed to existing CAD and the remaining 510 (26.8%) of the 1900 patients did not exhibit any angina symptoms during their daily activities. Functional testing for myocardial ischemia was not performed in 833 patients (43.8%). Myocardial scintigraphy was the most commonly used noninvasive technique (644 patients, 34%), while 492 patients (25.9%) had an exercise test and 159 (8.4%) underwent stress echocardiography.
Conclusion: Real-world data in this specific high-risk population of diabetic patients with SCAD offer the opportunity to identify and improve diagnostic and therapeutic practice in the healthcare system of a European Union country.
