The article aims to evaluate and compare the clinical-anamnestic parameters and carbohydrate metabolism in patients diagnosed with CHD and DM2 across various categories of LVEF. Keywords: type 2 diabetes mellitus; coronary heart disease; heart failure; cardiovascular events; ejection fraction. Introduction. Patients with T2DM are at higher risk of death and cardiovascular outcomes than the general population. Epidemiological studies have shown that in the next 20 years the number of patients suffering from T2DM will double [4]. This group of patients faces two main problems: the prognosis of the disease worsens and the number of drugs that doctors prescribe to them increases. NGLT-2 are a class of anti-diabetic drugs that can improve the quality of life and prognosis in patients with CHF in combination with T2DM, occurring in 12–46% of cases [2]; [3], as well as in the absence of DM-2 [1]. Expected results from ongoing studies will determine whether SGLT-2 inhibitors have an impact on patient-centered endpoints, including physical activity and quality of life [5]. Thus, the interaction of IHD and T2DM is accompanied by a significant risk of CVD complications. This highlights the need to continually monitor and optimize patient treatment strategies based on their individual characteristics. Purpose: Analysis of the comparative frequency of occurrence of clinical and anamnestic parameters and assessment of the carbohydrate profile in patients with coronary artery disease with diabetes mellitus-2 with different categories of LVEF during the observation stages. Material and methods. The study included 130 patients with diabetes mellitus 2 (WHO, 1999) and coronary artery disease (EOC) at the age of 65.6 ± 9.7 years, the duration of diabetes mellitus 2 and coronary artery disease was 8.8 ± 5.2 and 7.5 ± 3 ,6 years respectively. Demographic parameters were analyzed: age, AMI, stroke/TIA, history of COVID, history of type 2 diabetes, AF (paroxysm), PCI, CABG, CE, history of asthma. Depending on LVEF, patients are divided into two subgroups (A 1 – EF <41-49% and B group EF>50%). Then, according to the H2FPEF scale [6], to determine the probability of HF, patients with shortness of breath and preserved EF with increased BNP (B) are divided into 2 subgroups: subgroup 2 (with a probability of HF >50%) and 3 (with a probability of HF <50%). Of the 92 parameters we analyzed, only data with statistically significant differences were selected for discussion and the full lipid spectrum, fasting SCIENCE AND INNOVATION INTERNATIONAL SCIENTIFIC JOURNAL VOLUME 4 ISSUE 12 DECEMBER 2025 ISSN: 2181-3337 | SCIENTISTS.UZ 77 and PPG, HbA1c, CRP, BNP, vitamin D, sUA, and LVEDP were determined. Also Basic therapy: anticoagulants, antiplatelet agents, nitrates, beta blockers, RAAS blockers, statins, empagliflozin, antihypertensive drugs. The observation period was 2 years. Static processing was carried out using the nonparametric one-factor Kruskal–Wallis analysis of variance. Results. Assessing the clinical characteristics of those examined: AMI, AF, CABG, a history of stroke were suffered in group A versus B: 50.0% (30) - 23.2% (16) (t=27.030; P=0.000); 21.3% (13) -1.4% (1) (t=23.525; P=0.000); 8.3% (5) -10.1% (7) (t=0.504; p=0.478); 6.7% (4) – 4.28% (3) (t=0.258, p=0.612). That is, the number of patients with a history of AMI and EF in the group with moderately reduced LVEF was 2.3 and 5 times higher, respectively, than with preserved LVEF. In terms of experience with Covid during the pandemic, no intergroup differences between groups A and B are recorded - 50.0% (30) versus 55.9% (39), as well as between groups 2 and 3 - 56.5% (13) versus 55.3 % (26) (t=0.059; p=0.809). During the two-year observation period, all of the above parameters had a statistically significant decrease in their number on average p = 0.000. The only parameter is PCI, which is 1.7 times higher in group 3 (p = 0.007) versus 2, but over 2 years of follow-up with 0% of cases versus group 2 4.3%. All patients had concomitant hypertension - 100% (130), DM-2 - in 100% (130), dyslipidemia - 100% (130), 54.8% (74) were smokers, the number of patients over 60 years old was 74.6 % (97) (Table 1).
