Abstract

Aim of the study was to evaluate the right ventricular function (RVF) in highlanders (HL) with sleep-related respiratory disturbance. Method: 36 male HAR of Sary-Mogol (Alay region, Kyrgyzstan, 3000 m) were investigated (mean age 40.1 ± 9.01 years, BMI 26.4 ± 3.9 kg/m2). The study included the physical examination, spirometry, tissue Doppler echocardiography and polysomnography. Subjects were divided into two groups. The first group consisted of the HL with apnea – hypopnea index (AHI) 15. The results were presented in table 1 Conclusion: Thus HL with AHI >15 had significantly increased the MPI RV and decreased S’ RV and Em/Am RV indices, that can point to modulation of the RVF and latent RV systolic dysfunction. To confirm this result the further investigation should be performed on more subjects.
