Obstructive sleep apnoea syndrome (OSAS) does not increase aortic root size. Age and sex, not arterial hypertension, were linked to aortic dilatation in patients with OSAS.
Area of Science:
- Cardiology
- Sleep Medicine
- Vascular Biology
Background:
- Obstructive sleep apnoea syndrome (OSAS) is linked to cardiovascular diseases.
- The impact of OSAS on aortic root dimensions remains under-investigated.
- This study aimed to assess aortic root diameter and stiffness in OSAS patients.
Purpose of the Study:
- To investigate the relationship between OSAS and aortic root diameter.
- To evaluate aortic stiffness in individuals with OSAS.
- To identify predictors of aortic root dilatation in this population.
Main Methods:
- 76 patients with OSAS underwent transthoracic Doppler echocardiography.
- Aortic diameter, aortic regurgitation, left ventricular parameters, and pulmonary artery pressure were measured.
- Carotid-femoral pulse wave velocity was used to assess aortic stiffness.
Main Results:
- The prevalence of aortic root dilatation was 3.9% in the study cohort.
- Mean aortic root diameter was 35.3 +/- 3.8 mm.
- Univariate analysis revealed age and sex as significant predictors of aortic root dilatation, but not arterial hypertension.
Conclusions:
- Aortic root enlargement is not more prevalent in patients with OSAS.
- Age and sex are associated with aortic dilatation, independent of OSAS.
- Arterial hypertension was not found to be a predictor of aortic dilatation in this cohort.
