The rheological properties of blood and the risk of cardiovascular disease in patients with obstructive sleep apnea syndrome (OSAS)

Folia Histochemica et Cytobiologica, 2011
Obstructive sleep apnea (OSA) is an important public health concern, which affects around 2–4% of the population. Left untreated, it causes a decrease not only in quality of life, but also of life expectancy.
