Numerous studies have demonstrated an increased prevalence of bradyarrhythmias in OSA patients. The classic study by Guilleminault et al looked at 400 patients with OSA.
Among multiple comorbidities, sleep-disordered breathing (SDB), and obstructive sleep apnea (OSA), in particular, are the most common. Almost 50% of patients with HF have alterations of ventilation during sleep that can disrupt the positive effects of physiological sleep on the cardiovascular system. In two studies of patients with HF undergoing polysomnography, OSA was detected in 37% and 11% of patients.
Sudden cardiac death (SCD) is defined as an “unexpected natural death from a cardiac cause within a short time period, generally ≤1 hour from the onset of symptoms, in a person without any prior condition that would appear fatal.”
AFib affects 6 million lives in the US.1 Each year ~350,000 patients undergo an ablation procedure to treat this condition. Intracardiac AFib ablation carries significant risk. In particular, complications associated with the transeptal puncture and esophageal fistulas are associated with significant cost to the healthcare system and the patient.
Research linking AFib to sleep apnea has been steadily increasing. But the awareness that sleep apnea is a risk factor for AFib so far remains low. A recent survey of 1,013 Americans found that while nearly half are aware that the risk of developing AFib is increased by family history (48%) and hypertension (43%), only 16% knew that sleep apnea is a risk factor.
The increased awareness and broad acceptance of the role of sleep apnea in cardiac disease, and the main studies and scientific statements published by the European Society of Cardiology, American Heart Association, and American College of Cardiology were the drivers behind the American Sleep Academy’s “Sleep Apnea Hurts Hearts” campaign.
COVID 19 took us from full practice schedules to limping along with a 55% decrease in revenue and a 60% decrease in volume. Continue see patients. Here’s how.
On November 1st, CMS released the 2020 Medicare Physician Fee Schedule. The final payment rates for home sleep tests are in keeping with the changes initiated by CMS last year.
New diagnostic tools such as the WatchPAT device allow simple testing and classifying of sleep apnea even when the sleep and cardiology offices are located apart geographically.
