Western scientists have frequently been guilty of (re)discovering something that’s been around for many centuries, attempting to package it as something new, and in the process depriving it of its cultural heritage in the name of sanitising it for scientific examination. Of course, given the track record of the West, the outrage is perfectly understandable. ![]() The outrage on display seems prompted by Scientific American‘s tweet, rather than the article itself, which makes multiple flattering references to pranayama, yoga and the knowledge of the East. ![]() scientific language as "cardiac coherence breathing"! It's taking the West a few millennia to learn what our ancients taught us millennia ago, but hey, you're welcome… Follow-up sleep testing should be performed to assess the effectiveness of treatment.ĪHA Scientific Statements cardiovascular disease clinical manifestation complications diagnosis epidemiology obstructive sleep apnea therapy.A recent article in Scientific American on the benefits of “proper breathing” for overall health has ignited anger across social media, with many in India accusing the magazine of rebranding or even appropriating the ancient Indian breathing technique of ‘pranayama’.ĭetailed description of the benefits of the 2500-year-old Indian technique of pranayama, dressed up in 21st c. Continuous positive airway pressure should be offered to patients with severe OSA, whereas oral appliances can be considered for those with mild to moderate OSA or for continuous positive airway pressure-intolerant patients. All patients with OSA should be considered for treatment, including behavioral modifications and weight loss as indicated. ![]() Patients with nocturnally occurring angina, myocardial infarction, arrhythmias, or appropriate shocks from implanted cardioverter-defibrillators may be especially likely to have comorbid sleep apnea. After stroke, clinical equipoise exists with respect to screening and treatment. In patients with tachy-brady syndrome or ventricular tachycardia or survivors of sudden cardiac death in whom sleep apnea is suspected after a comprehensive sleep assessment, evaluation for sleep apnea should be considered. In patients with New York Heart Association class II to IV heart failure and suspicion of sleep-disordered breathing or excessive daytime sleepiness, a formal sleep assessment is reasonable. We recommend screening for OSA in patients with resistant/poorly controlled hypertension, pulmonary hypertension, and recurrent atrial fibrillation after either cardioversion or ablation. Despite its high prevalence in patients with heart disease and the vulnerability of cardiac patients to OSA-related stressors and adverse cardiovascular outcomes, OSA is often underrecognized and undertreated in cardiovascular practice. OSA prevalence is as high as 40% to 80% in patients with hypertension, heart failure, coronary artery disease, pulmonary hypertension, atrial fibrillation, and stroke. Sleep disturbances are common and underdiagnosed among middle-aged and older adults, and the prevalence varies by race/ethnicity, sex, and obesity status. Approximately 34% and 17% of middle-aged men and women, respectively, meet the diagnostic criteria for OSA. ![]() Obstructive sleep apnea (OSA) is characterized by recurrent complete and partial upper airway obstructive events, resulting in intermittent hypoxemia, autonomic fluctuation, and sleep fragmentation.
