Summary
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.
