Obstructive sleep apnea can impair right ventricular function in nearly 28% of patients. Gated radionuclide ventriculography can detect these early cardiac changes, even without increased pulmonary artery pressures.

Area of Science:

  • Cardiology
  • Sleep Medicine
  • Nuclear Cardiology

Context:

  • Obstructive sleep apnea (OSA) is a prevalent condition with known cardiovascular implications.
  • The impact of OSA on right ventricular (RV) function remains incompletely understood.
  • Limited data exist on evaluating RV function in OSA patients using non-invasive techniques.

Purpose:

  • To investigate the influence of obstructive sleep apnea on right ventricular function.
  • To assess the utility of gated radionuclide ventriculography (GRNV) in detecting RV dysfunction in OSA patients.

Summary:

  • Gated radionuclide ventriculography was performed on 68 patients with verified obstructive sleep apnea.
  • Impaired right ventricular function was observed in 27.9% of the patients.

  • No correlation was found between RV function and the severity of OSA or pulmonary artery pressures.

    • Impact:

    • Gated radionuclide ventriculography is a valuable tool for the early detection of subclinical right ventricular dysfunction in obstructive sleep apnea.
    • Findings suggest a direct detrimental effect of OSA on RV function, independent of pulmonary hypertension.
    • This highlights the importance of assessing RV function in OSA management.
