O bjec tiv e: to assess the contribution of anemia and latent iron deficiency (LID) to the formation of acute decompensation of chronic heart failure (ADHF) in patients with diabetes mellitus (DM) type 2 in history. Ma t erialsand methods: a one‑time screening clinical non‑randomized study was conducted. 98 patients with ADHF were examined according to the criteria for inclusion and non‑inclusion, among which 47 (48%) patients suffered from type 2 DM. Among patients with impaired carbohydrate metabolism, 14 (29.8%) patients had an anemic syndrome verified. Results : the prevalence of anemia among hospitalized patients with ADHF against the background of type 2 DM was 29.8%, LID without anemia – 51.5%. Anemic syndrome in patients with ADHF and type 2 DM was represented by iron deficiency anemia in 85.7% and anemia of chronic conditions in 14.3% of cases. In 2/3 of the patients, anemia corresponded to moderate severity. The relative risk (RR) of the development of ADHF against the background of type 2 DM and anemia increases by 2.4 times, in the presence of LID – by 2.9 times. The presence of coronary artery disease, myocardial infarction in history, atrial fibrillation with a heart rate of more than 110 beats per minute, renal dysfunction, high activity of nonspecific inflammation were risk factors for the formation of ADHF in patients with type 2 DM and anemia. The presence of left ventricular hypertrophy in patients with anemia increased the RR of the development of ADHF by 1.8 times, the presence of chronic kidney disease – by 1.7 times, with an increase in the excretion of albumin/protein in the urine >30 mg/g – by 5.7 times, with tubular dysfunction – by 2.4 times, with an increase in aortic stiffness – by 3.5 times. Conclusion: the prevalence of anemia and LID among patients with ADHF and type 2 DM is high. These conditions were risk factors for the development of ADHF and its progression. ADHF in patients with type 2 DM against the background of anemia and LID was characterized by a more severe course, a more pronounced lesion of the target organs.
