Aim . To assess the dynamics of the main echocardiographic parameters in patients with chronic obstructive pulmonary disease (COPD) and early-stage chronic kidney disease (CKD) taking native vitamin D. Material and methods . The study included 264 patients, which were divided into two groups: experimental group (n=135) — patients with stage 2-4 COPD (men, mean age — 72,2±3,8 years, mean disease duration — 23,1±3,4 years); control group (n=136) — patients with stage 2-4 COPD, comparable in age and sex. Patients of both groups were divided into 4 subgroups depending on forced expiratory volume in 1 second and vitamin D levels. In the experimental group, native vitamin D therapy was performed according to regimen that maintains its level >34,3 ng/ml during the year; in the control group — according to the Russian Association of Endocrinologists guidelines. Echocardiography was performed for all patients at the beginning and end of the study. Results. In all subgroups of the experimental group, a statistically significant increase in the left ventricular ejection fraction was revealed (p 34,3 ng/ml for 12 months in patients with COPD and early-stage CKD was associated with a significant improvement in myocardial remodeling. This indicates an improvement in cardiovascular adaptation and function.
