Obstructive sleep apnea (OSA) have been reported to be a risk factor for cardiovascular disease. A decade-long research study was done using the database of over 10,000 individuals who underwent sleep testing.
What are cardiovascular events?
It is a class of disease that involves heart or blood vessels. Cardiovascular disease includes but not limited to heart attack, hypertension, stroke, heart failure, angina, or thromboembolism (formation of blood clots). To assess the effect of sleep apnea researchers studied its association with the risk of occurrence of cardiac events like myocardial infarction, stroke, exacerbation of congestive heart failure, and coronary artery bypass surgery. In comparison to normal population, people in high risk group are more prone to develop cardiovascular disease due to obstructive sleep apnea. The high risk group includes elderly people, male gender, prior diabetes, prior hypertension, prior stroke, prior MI, prior CHF, prior COPD, and smokers.
