Using hand-made SASD-14 to evaluate the relationship between hypertension and obstructive sleep apnea syndrome

Abstract

Sleep apnea syndrome (SAS) is one of the causes of hypertension, relating to cardiovascular risk and cardiovascular disease, independently associated with other risks. Method Cross-sectional study with the short-term follow up and compare to the control group. Include 230 patients: 134 hypertension patients and 96 non-hypertension patients. We using hand-made SASD-14 (Sleep Apnea Syndrome Detective-2014), compare with portable polysomnography StarDust II combine with clinical symptoms to diagnose obstructive sleep apnea syndrome. Result (1) AHI in the OSAS patients with hypertension is 29.77 ± 13.03, higher than AHI in the OSAS patients without hypertension 25.21 ± 14.37 (p < 0.05). (2) There are strong positive correlation between AHI and systolic blood pressure with r = 0.407, p < 0.001. In multivariable analysis the affect of cardiovascular risk to AHI: two risks with statistic signification are degree of hypertension (p < 0.01) and obesity (p < 0.05). (3) The Kappa index for the SASD-14 compare with StarDust II is 0.775 (p < 0.01). Conclusion There is the signification relationship between hypertension and OSAS; SASD-14 can be use for diagnosing obstructive sleep apnea syndrome.
