[The research progress of OSAHS and cardiovascular disease]

Obstructive sleep apnea hypopnea syndrome(OSAHS) is characterized by recurrent stenosis or occlusion of upper airway during sleep. Although the controversy is far from over, this syndrome could often lead to different cardiovascular diseases(CVD) with those complicated pathophysiologic mechanisms, including hypertension, coronary heart disease, heart failure and cardiac arrhythmia. The objective of this article is to elaborate these related pathogenesis, and further to investigate the relationship between OSAHS and CVD. Besides, as one kind of effective and economical treatment, continuous positive airway pressure(CPAP) should be attached enough importance in the therapy of CVD with OSAHS.
