Can peripheral saturation predict the existence of obstructive sleep apnea syndrome (OSA) in a population followed for atrial fibrillation (AF)?

Introduction: OSA has a polygraphic definition based on the HAI. It generates nocturnal desaturation responsible for cellular hypoxia with multi-visceral impact mainly cardiac such as arrhythmias.The purpose of our study was to investigate whether peripheral saturation can be a means of descrambling to diagnose OSAS in a population followed for AF.Methods: Analytical prospective study including 100 patients followed for AF. None of the recruited patients had been followed for OSA before. Each patient had a clinical examination and a polygraphy. Patients were divided into 2 groups: G1: with OSA and G2: without OSA.Results: The mean age was 66.4 ± 9.7 years with a sex ratio at 0.81. The average BMI was 28.57 ± 4.81 kg / m2. Hypertension was the most common risk factor (72%). The most common symptoms were nocturnal snoring (87%), memory problems (73%), morning sickness (66%), sleep impairment (60%) and mild sleepiness (47%). The prevalence of OSA was 90%. It was classified as mild, moderate and severe in 30, 29 and 31 patients, respectively. The mean HAI was 21.69 ± 13.67. Comparison of the 2 groups showed that the desaturation index and total desaturation time were statistically higher in G1 (20.8 vs 3.2 desat / h, p

Conclusion: We demonstrated the feasibility for reliable ovulation detection and prediction with high-frequency temperature data collected by a non-invasive wearable device. Significance: Traditional fertility monitoring methods are often either inaccurate or inconvenient. The wearable device and learning algorithm presented in this paper provide a user friendly and reliable platform for tracking ovulation, which may have a broad impact on both fertility research and real-world family planning.

Conclusion: Regional electrophysiology and paths in the model match human action potentials, dynamic behavior, and cardiac activation sequences. Connected in closed loop with a pacing device in DDD mode, the model generates complex arrhythmia such as atrioventricular nodal reentry tachycardia. Such device-induced outcomes have been observed clinically and we can establish the key physiological features of the heart model that influence the device operation. Significance: These findings demonstrate how an abstract heart model can be used for device validation and to design personalized treatment.

Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this techniqu...

In conclusion, the STOP-BANG questionnaire is sensitive; however, it has a low specificity with a high false positive rate. Given that a large number of atrial fibrillation patients need testing for OSA, we recommend the use of a level II sleep study regardless of the results of the screening questionnaire. This approach accurately identifies OSA and may limit the cost of unnecessary level-I sleep studies. PMID: 29682848 [PubMed - as supplied by publisher]

We examined whether patients at increased risk for OSA, assessed by the STOP-BANG (snoring, tired during the day, observed stop breathing during sleep, high blood pressure, body mass index more than 35 kg/m, age more than 50 years, neck circumference more than 40 cm, and male gender) questionnaire, had a higher incidence of new-onset postoperative atrial fibrillation after cardiac surgery. Because both postoperative atrial fibrillation and OSA increase resource utilization, we secondarily examined whether patients at increased OSA risk had longer duration of postoperative mechanical ventilation and intensive care unit (ICU...

You're reading Does Snoring Have Any Health Risks?, originally posted on Pick the Brain | Motivation and Self Improvement. If you're enjoying this, please visit our site for more inspirational articles. For a long time, people have categorized snoring as simply a minor health condition that will go away on its own. However, modern research has declared that snoring is not only irritation to the ears and to peaceful sleep but an indication of a number of complaints in your body. People who are overweight, who are regular smokers or have high cholesterol are prone to snoring, obstructive sleep apnea (OSA). OSA is defi...

We here describe a typical but rarely documented case which clearly indicates a strong link between SDB and cardiovascular disease. A 68-year-old woman complaining of frequent palpitations was referred to our institute. An electrocardiogram (ECG) at a previous clinic had shown atrial fibrillation, although it had already returned to...
