Snoring is a common disorder that affects millions of people around the world. Even though normal snoring is not dangerous to human health, repeated respiratory arrests during the snoring process can put the snorer's life in danger. According to a study by the American Heart Association (2012), repeated respiratory arrests during the snoring process are dangerous and can lead to the development of cardiovascular problems and even death. This condition is known as sleep apnea. In this regard, a person suffering from sleep apnea experiences repeated respiratory arrests up to thirty times per hour when sleeping. Such episodes are dangerous for the snorer because they increase the risk of developing heart failure, high blood pressure, stroke and arrhythmias. Research shows that one in five people have sleep apnea. America, in particular, has one of the highest incidences of people with this disease. According to Lettieri (2010), approximately 15 million adults suffer from obstructive sleep apnea in America. The majority of people with sleep apnea are patients with cardiovascular problems and hypertension. As mentioned earlier, this disease is life-threatening and requires early treatment. This paper will review the historical evidence of the disease, its causes and clinical effects on the cardiovascular system, its complications and prognosis. The talk will also explore treatments and research associated with the disease. Historical Evidence Javaheri, Caref, Chen, Tong, and Abraham (2011) define sleep apnea as a condition characterized by repeated respiratory arrests in the process of snoring. The episode usually occurs up to 30 times per hour. Sleep apnea affects one in five adults. Currently, an estimate...... in the middle of an article ......ngs published by researchers at the Canadian Medical Association noted an increase of approximately 20% in cases of pneumonia in patients suffering of sleep apnea, as noted by Jilek et al. (2011).ConclusionSleep apnea is a health disorder characterized by repeated respiratory arrests during sleep. Research shows that one in five adults suffer from sleep apnea. In the United States, approximately 15 million adults suffer from this disease. Sleep apnea is associated with a variety of complications, including high blood pressure, heart disease, type 2 diabetes, acid reflux, adult asthma, and car accidents, among others. Nonetheless, the condition can be treated using a number of techniques, including behavioral therapy, surgeries, CPAP, APAP, and VPAP, among others. Therefore, patients suffering from sleep apnea should seek treatment as early as possible, as the condition is easily manageable if treated early enough..
