Course and treatment of diabetes: from cardiovascular risk to catastrophe. Clinical case

As of today, type 2 diabetes mellitus and its complications impose a significant burden on healthcare systems worldwide. Myocardial infarction stands as a leading cause of death among patients with type 2 diabetes mellitus due to macroangiopathy resulting from glucose metabolism disorders and endothelial damage 5. Unfortunately, even with timely assistance, patients with myocardial infarction may develop mechanical complications such as cardiac aneurysm, posing serious risks of myocardial wall rupture with a high likelihood of fatality. In most cases, interventricular septal rupture occurs, manifesting in 0,21% of cases of ST-segment elevation myocardial infarction (STEMI) and 0,04% of cases of non-STEMI. Surgical correction of the defect remains the only effective treatment method, albeit associated with a high risk of mortality. Consequently, intra- and post-operative complications in such patients prompt the search for alternative treatment modalities, including transcatheter closure of the defect 6. Interventricular septal rupture more commonly occurs in older patients, women, those with hypertension, and chronic kidney disease. Typically, the defect arises against the backdrop of the first myocardial infarction in the absence of timely or absent reperfusion therapy. Interventricular septal rupture may develop within 1–14 days after STEMI. However, the incidence usually demonstrates a bimodal peak within the first 24 hours or 3–5 days after the infarction 12. A clinical case of a patient with combined cardiometabolic pathology, namely, severe type 2 diabetes mellitus and post-infarction interventricular septal defect, is presented. The case underscores the issue of comorbidity in severe patients. Successful treatment of the patient was achieved through collaborative efforts of cardiac surgeons, intensivists, cardiologists and endocrinologists.
