Prevalence of obstructive sleep apnea in primary care patients with hypertension
1Division of Clinical Medicine Faculty of Medicine University of Tsukuba Tsukuba Japan.
Background:
As the number of patients with hypertension who have obstructive sleep apnea (OSA) might be underestimated, this study aimed to explore the prevalence of OSA and develop a diagnostic algorithm for moderate or severe OSA among primary care (PC) patients with hypertension.
Methods:
This multicenter cross-sectional study enrolled patients diagnosed with hypertension aged 18 years or older in Japan from October 2012 to September 2014.
Results:
Forty-nine patients (64.5%) had 22 or more obstructive respiratory events during sleep.
Conclusions:
The prevalence of OSA among PC patients with hypertension might be much higher than previously thought.
