The aim of this study is to characterize the clinical and polysomnographic features in a population of snorers. Methods： A total of 490 subjects were examined retro- spectively. The clinical history, Epworth Sleepiness Scale （ESS） scores, physical examination, and full-night poly- somnography （PSG） data were obtained for all the subjects. The correlations between the neck circumference, waist circumference, ESS scores, body mass index （BMI）, and apnea-hypopnea index （AHI） of obstructive sleep apnea （OSA） patients were explored. The gender and age differences in OSA patients were analyzed. Results： OSA was diagnosed in 84.7% of the sample, with 21.2% of the patients having a mild form, 15.4% having a moderate form, and 63.4% having a severe form of OSA. The ESS scores, neck circumference, waist circumference, and BMI were posi- tively correlated with AHI in OSA patients. The ESS scores and BMI were negatively correlated with nadir oxygen saturation （SaO2）. A greater number of men than women exhibited moderate to severe forms of the disease. OSA affects the work of males more commonly compared with females. Nocturia was a more common complaint in elderly OSA patients. Heart diseases coexisted more frequently with OSA in elderly patients. Conclusions： In a population of snorers, OSA is the most common condition identified. The ESS scores and BMI were well correlated with the severity of the disease. Men had a more severe form of OSA than women. Nocturia frequently occurred in elderly OSA patients, as did the coexistence of heart disease.展开更多

Methods： With the use of polysomnography, 262 adult habitual snorers were examined and divided into the OSAHS group and the Non-OSAHS group （control）. Using ambulatory electrocardiogram and blood pressure measurement, daily nocturnal rhythm of blood pressure, hypertension, heart rate variability, some arrythmias and angina pectoris of coronary heart disease were monitored and compared between the two groups, before and after 14 days of treatment with NCPAP in the OSAHS group. Results.This study indicated a higher incidence （39.6%） of OSAHS in adult snorers and demonstrated that there was a significantly higher incidence of hypertension, disappearance of the daily nocturnal rhythm of blood pressure, poor effectiveness of nitrate on angina pectoris of coronary heart disease, decreased heart rate variability during sleep, increased arrythmias and lower SpO2 levels in the OSAHS group than in the Non-OSAHS group. After NCPAP treatment during sleep, snoring control, significantly higher SpO2 and lower apnea hypopnea indices were achieved in the OSAHS group; heart rate variability and daily nocturnal rhythm of blood pressure returned to normal levels. Conclusion：The results of this research suggested that there was a close relationship between the development of OSAHS and some cardiovascular disorders. Furthermore, NCPAP treatment was effective not only on OSAHS but also on coexisting cardiovascular disorders.展开更多

Methods: A prospective single blinded randomised controlled trial was conducted in the otolaryngology department of a UK teaching hospital (Exeter). 127 adult patients with a history of simple snoring or sleep apnoea were recruited. 93 patients completed the study. Patients were excluded because of severe sleep apnoea (apnoea index > 40), or morbid obesity (BMI > 40). The study group completed a self-guided treatment programme of singing exercises contained on a 3CD box set, performed for 20 minutes daily. Outcome measures included the Epworth Sleepiness Scale, the SF-36 generic quality of life assessment tool, visual analogue scales (VAS range 0-10) of snoring loudness and frequency, and visual analogue scale of compliance (for intervention group). Results: The Epworth scale improved significantly in the experimental group compared to the control group (difference -2.5 units;95% CI -3.8 to -1.1;p = 0.000). Frequency of snoring reduced significantly in the experimental group (difference -1.5;95% CI -2.6 to -0.4;p = 0.01), and loudness of snoring showed a trend to improvement which was non-significant (difference -0.8;95% CI -1.7 to 0.1;p = 0.08). Compliance with exercises was good;median 6.6 (quartiles = 4.1, 8.3). Conclusions: Improving the tone and strength of pharyngeal muscles with a 3 months programme of daily singing exercises reduces the severity, frequency and loudness of snoring, and improves symptoms of mild to moderate sleep apnoea.展开更多

Objective: The objective of this study was to record subjective and objective sleep parameters and to analyze the effects of alternating of sleeping arrangements in snorers and their bed partners. Methods: Habitual snorers and their bed partners were recruited via newspaper articles not stating the exact purpose of the study. Both filled out a 90-day sleep diary. During this time, we recorded subjective and objective sleep parameters in the snorers and their bed partners via wrist actigraphy and sleep diaries for 14 days. For statistical analysis, we used two-sided t-tests and Spearman’s Rho. Results: The dataset included 45 snorers (11 females) and 45 bed partners (34 females) with a mean age of 47 ± 13 and 43 ± 12 years. Screening for sleep apnea yielded snoring without OSAS, mild-, moderate- and severe OSAS in 27 (60%), eight (18%), three (7%) and six (15%) snorers. PSQI total scores were significantly lower in snorers than in bed partners (4 ± 2 vs. 6 ± 4, p = 0.002). We could not find a significant correlation between subjective and objective sleep latency and efficiency. Couples who changed their sleeping arrangement were significantly younger than those who habitually slept alone or together (p = 0.01). Subjective sleep parameters of snorers or bed partners were not related to the number of consecutive nights spent either together or apart. Conclusions: Our study confirmed the weak correlation of subjective and objective sleep parameters in pairs with snoring problems. Couples changing their sleeping arrangement were the youngest among the whole group, but their separation of sleeping arrangements did not improve subjective sleep parameters.展开更多

METHODS: With the use of polysomnography, 73 elderly snorers (older than 60 years) were examined and placed into either the SAHS group or the control group. Using ambulatory electrocardiogram (ECG) and blood pressure measurement, daily nocturnal rhythm of blood pressure, hypertension, heart rate variability, some arrhythmia and angina pectoris of coronary heart disease (CHD) were monitored and compared between the two groups before and after 5 - 7 days of treatment with nasal continuous positive airway pressure on the SAHS group. RESULTS: This study indicated a higher incidence (47.9%) of sleep apnea syndrome in elderly snorers and demonstrated that there was a significantly higher incidence of hypertension, disappearance in daily nocturnal rhythm of blood pressure, poor effectiveness of nitrate on angina pectoris of coronary heart disease, decreased heart rate variability during sleep, increased arrhythmia and lower pulse oxygen saturation (SpO(2)) levels in the SAHS group than in the control group. After nasal continuous positive airway pressure treatment during sleep, snoring control, significantly higher SpO(2) levels and lower index of apnea/hypopnea were achieved in the SAHS group; heart rate variability (HRV) and blood pressure day nocturnal rhythm were returned to normal levels. CONCLUSION: This research suggests that there is a close relationship between the development of sleep apnea syndrome and some cardiovascular diseases. Continuous positive nasal airway pressure is effective not only on SAHS but also on coexisting cardiovascular disorders.展开更多
