Fig. 1. The study included 91 patients, who were then distributed into 3 groups depending on their blood sugar levels. Patients with FPG ≥ 7.0 mmol/L (measured in two repeated tests) were diagnosed with type 2 DM and prescribed adequate treatment. Patients with FPG between 6.1 and 6.9 mmol/L underwent an oral glucose tolerance test (OGTT). Patients with FPG between 5.6 and 6.0 mmol/L who were at risk for developing type 2 DM and metabolic syndrome also underwent OGGT. FPG — fasting plasma glucose
Fig. 2. The overall distribution of the patients depending on the severity of carbohydrate metabolism disorders revealed by OGTT. IFG — impaired fasting glucose; IGT — impaired glucose tolerance; OGTT — oral glucose tolerance test
Fig. 3. The distribution of the patients depending on the severity of carbohydrate metabolism disorders revealed by OGTT in the group of 35 individuals with initial FPG between 5.6 and 6.0 mmol/L. IFG — impaired fasting glucose; IGT — impaired glucose tolerance; OGTT — oral glucose tolerance test
Fig. 4. The distribution of the patients depending on the severity of carbohydrate metabolism disorders revealed by OGTT in the group of 34 individuals with initial FPG between 6.1 and 6.9 mmol/L. IFG — impaired fasting glucose; IGT — impaired glucose tolerance; OGTT — oral glucose tolerance test
Table 1. Clinical and demographic characteristics of patients
Note: *— differences are significant, р < 0.05; BMI — body mass index; IFG — impaired fasting glucose; IGT— impaired glucose tolerance; AMI — acute myocardial infarction; ACE — acute cerebrovascular event; WC — waist circumference; OGTT— oral glucose tolerance test; DM — diabetes mellitus; TIA — transient ischemic attack.
Table 2. The distribution of the patients depending on the severity of carbohydrate metabolism disorders (OGTT)
Note: *— differences are significant, р < 0.05; FPG — fasting plasma glucose; IFG — impaired fasting glucose; IGT— impaired glucose tolerance; OGTT— oral glucose tolerance test; DM — diabetes mellitus. In the subgroup of patients with FPG levels ranging from 5.6 to 6.0 mmol/L, there were 2.8% cases of IFG, 11.5% cases of IGT and 4.3% cases of type 2 DM (based on OGTT results). Thus, the frequency of prediabetic conditions in the subgroup was 14.4%. The frequency of IGT was significantly lower in the subgroup with FPG between 6.1 and 6.9 mmpl/L.
