NCT05040516

Brief Summary

The aim of the study is to determine whether selenoprotein activity and blood renalase level correlate with subclinical hypertensive heart disease and obstructive sleep apnea. The correlation will be assessed using selected electrocardiographic, ultrasound and laboratory indicators.

Outcome Measures

Primary Outcomes (5)

  • Assesment of blood renalase level

    The Enzyme-linked immunosorbent assay (ELISA) to know blood renalase level

    One day

  • Assesment of blood selenoprotein P level

    The Enzyme-linked immunosorbent assay (ELISA) to know blood selenoprotein P level

    One day

  • Assesment of the severity of obstructive sleep apnea

    Full polysomnography

    One day

  • Assessment of arrhythmias

    24-hour Holter ECG monitoring

    One day

  • Assessment of arrhythmias and cardiac morphology

    Echocardiography

    One day

Secondary Outcomes (1)

  • Assesment of Blood Total Antioxidant Status (TAS)

    One day

Study Arms (1)

Group 1

The planned procedures include: medical interview, physical examination with basic anthropometric measurements (age, height, body weight); biochemical tests including blood selenium, selenoproteins, renalase and creatinine levels; total antioxidant status (TAS), 24-hour Holter electrocardiography, polysomnography and echocardiography. A 10 ml of venous blood sample will be collected by venopuncture. Laboratory tests will be performed using commercially available standardized tests.
