Abstract
Aim. To analyze the relationship between metabolic disorders and obesity with hemodynamic parameters and the severity of the condition of patients with chronic thromboembolic pulmonary hypertension (CTEPH) based on the POLET register.
Materials and methods. The study included patients with CTEPH from the POLET register. Data from medical history, lipid profile, glycemia, uric acid level, weight, height, functional class (FC), distance in the 6-minute walk test (6MWT), echocardiography, and right heart catheterization were used for analysis.
Results. The study included 84 patients 60±14 years old, including 45 men. The majority of patients had FC III – 51 (65%), which corresponded to 6MWT – 338±113 m. Nineteen (23%) people had experience in taking PAH specific therapy, 37 (46%) had cardiovascular comorbidity. In the general group, the body mass index (BMI) was 25.7±4.5 kg/m2, and normal glycemia, lipid profile, and uric acid levels were also determined. mPAP was 51±12 mmHg, RA area was 25.5 (20; 30) cm2. Correlations were identified between: RA area and the level of total cholesterol (r=0.60; p<0.01), triglycerides (r=-0.24; p<0.001), LDL cholesterol (r=0.75; p=0.04), uric acid (r=0.75; p=0.03); total cholesterol and 6MWT (r=0.44; p=0.04). Analysis of metabolic disorders, FC and comorbidity revealed differences between FC III and IV groups in the level of HDL cholesterol (p=0.02) and triglycerides (p<0.01).
Conclusion. The POLET registry includes mainly older patients. Severe FC (87% – III and IV) may be a result of the older age and the presence of concomitant pathology in almost half of the patients. The discovered relationships between the area of RA and FC with lipid and purine metabolism were discovered for the first time, however, they correspond to the direction of the world scientific researches, are important due to the use of these indicators in the scale for calculating the risk of death in patients with PAH and require further development.
