Abstract

Abstract Introduction and aim Cardiovascular diseases (CVD) are among the most common and significant complications of type 2 diabetes mellitus (T2DM). Despite significant therapeutic progress in the prevention of CVD, T2DM remains a leading cause of major adverse cardiac events (MACE). Patients with T2DM and clinical manifestations of atherosclerotic CVD, or those at high risk of developing it, should receive cardioprotective and nephroprotective medications such as GLP-1 receptor agonists (GLP-1) and SGLT-2 inhibitors (SGLT2). This study aims to determine to what extent patients undergoing treatment at the general practitioner (GP) level comply with the recommendations. Methodology Retrospectively, in the period January 2022 to September 2023, records in the EHR were reviewed in the five GP offices. For all patients ( ≥18 years) with DMT2, all demografic as well as data on chronic therapy, stage of chronic kidney disease (CKD), presence of any cardiovascular (CV) risk factors and/or history of cardiovascular diseases (CVD), and the therapy applied were observed. Results A total of 6,941 patients' data were reviewed, out of which 483 (6.96%) had a diagnosis of DMT2. Table 1. shows the characteristics of the study population. Table 2. presents the values of HbA1c according to the criteria of good, acceptable, and poor DMT2 control, as well as the CKD stage by eGFR. Among the associated comorbidities, the most common was arterial hypertension, observed in 79.5% of the participants, followed by obesity in 28.2%. In terms of the applied therapy, the majority of participants were on metformin (76.8%). There were no significant differences in body mass index (BMI) and glycemic control between the group with and without CVD. However, compared to the group without CVD, patients with both DMT2 and CVD had a higher frequency of SGLT2 inhibitors (27% vs. 18.5%) [chi²=4.336, df=1, p=0.032] and GLP-1 receptor agonists (10.7% vs. 4.6%) [chi²=6.336, df=1, p=0.012] use, but a lower frequency of metformin (67.9% vs. 81.2%) [chi²=10.510, df=1, p=0.001]. Discussion According to current guidelines, all patients with CVD and CKD should have SGLT2 inhibitors and/or GLP-1 receptor agonists in their therapy. Comparing our study with the CAPTURE study, our patients were older and had slightly fewer associated CVD (38.7% vs. 32.9%). According to the CAPTURE study, less than 25% of patients with DMT2 in therapy have an antidiabetic medication with proven cardiovascular benefit, while in our sample, this was the case for 31.4% of the participants. This suggests that progress is being made, but it is still insufficient. Conclusion Over the past decade, there has been a rapid increase in knowledge regarding the appropriate treatment and management of risk factors in the population of individuals with DMT2. Although new insights are continuously incorporated into guidelines, our study shows that implementation in practice lags.
