Obstructive Sleep Apnea reduce Blood Supply to the Heart – CPAP Treatment improved Blood Vessel Function

stethoscope - BSN

(Best Syndication News) - Researchers from the UK found that using Continuous Positive Airway Pressure (CPAP) equipment to treat obstructive sleep apnea helped improve blood vessel function. Sleep Apnea untreated had shown a reduced blood supply being delivered to the heart. The sleep apnea and blood function study results will be published in the Hypertension: Journal of the American Heart Association.

After 26 weeks of using CPAP equipment to treat obstructive sleep apnea, the study found improved blood supply function in the participants that were diagnosed with obstructive sleep apnea. CPAP equipment is constant air flow that delivered usually by a mask covering the nasal passages. This continuous airflow helps keep the airway passages open while the person with apnea sleeps at night.

Gregory Y.H. Lip, M.D., lead author of the study and professor of cardiovascular medicine at the University of Birmingham in the United Kingdom said even apparently healthy obstructive sleep apnea patients have abnormalities with their small and large blood vessels, which weaken the blood supply delivered to the heart muscle. Lip added that CPAP therapy is beneficial to improve this problem.

This study involved 108 participants that were seemingly healthy, were the same age, sex, BMI and smoking status. They divided the participants into three groups: 36 participants that had moderate to severe diagnosis of obstructive sleep apnea, but did not have high blood pressure; 36 participants that were diagnosed with high blood pressure but did not have obstructive sleep apnea; and the final 36 participants did not have high blood pressure nor did they have obstructive sleep apnea.

The control groups are the ones that did not use CPAP therapy, while the sleep apnea participants did use the CPAP equipment during the 26-week study.

Lip said that medical professionals should be on the lookout for patients that have obstructive sleep apnea and for cardiovascular disease.
