<p class="abstract"><strong>Background:</strong> Resistant hypertension, a special phenotype of hypertension, is associated with increased cardiovascular risk. Exercise and physical activity are recommended as non-pharmacological interventions to manage blood pressure in hypertension. Little is known about the effectiveness of exercise in resistant hypertension. A bidirectional relationship has been identified between resistant hypertension and obstructive sleep apnoea but the literature pertaining to the benefit of exercise for populations with both conditions, is minimal. This study aims to identify the effectiveness of exercise in reducing blood pressure in a cohort of adults with resistant hypertension and high risk of obstructive sleep apnoea.</p><p class="abstract"><strong>Methods:</strong> Dunedin based adults with resistant hypertension and high risk of obstructive sleep apnoea will be recruited from the community and health centres to participate in the study. Consenting volunteers (no. of fourteen) will participate in a 12-week exercise programme including aerobic and strength training. The primary outcome measure will be 24h ambulatory blood pressure while the secondary outcomes will be anthropometrics, activity parameters, sleep parameters, cardiac structure and function, and quality of life. The measurements at the end of the 12-week exercise programme will be compared with baseline to determine the effectiveness of exercise in reducing blood pressure in the cohort with resistant hypertension and risk of obstructive sleep apnoea.</p><p class="abstract"><strong>Conclusions: </strong>Exercise and physical activity are recommended to manage hypertension. Therefore, it is anticipated that the exercise programme will have a positive effect on the blood pressure of the participants. The findings have potential to change the direction of research in the area by filling the knowledge gaps.</p><p class="abstract"><strong>Trial Registration:</strong> The Ministry of Health, New Zealand (Ethics Ref: 18/CEN/257), Trial registry: ACTRN12618001881224p).</p>

ABSTRACT INTRODUCTIONPhysical inactivity is a risk factor for disease severity among people with obstructive sleep apnoea. AIMTo determine physical activity levels in patients at risk of obstructive sleep apnoea and explore their perceptions about barriers to participation in physical activity. METHODSThis was a cross-sectional observational study. Eligible participants were adults with symptoms of obstructive sleep apnoea hypopnea syndrome and Epworth Sleepiness Scale score ≥11, awaiting prioritisation for a diagnostic overnight sleep study at the local sleep clinic. Sixty participants (mean age±standard deviation: 51±12 years) each attended an individual appointment. Anthropometric measurements were taken and standardised questionnaires regarding quality of life, physical activity behaviour and perceptions of physical activity were completed. RESULTSOver one-third of the cohort did not meet World Health Organization guidelines for weekly physical activity. Hypertension, type 2 diabetes and obesity were also more prevalent in this subgroup. Low motivation and pain were commonly reported barriers to activity in participants not meeting the physical activity guidelines. Overall, 53 (88%) participants stated they would like to be more active. DISCUSSIONPhysical inactivity represents an additional risk factor for adults at high risk of obstructive sleep apnoea. Lack of motivation and pain were the most commonly perceived barriers to participation in activity. Physical activity interventions tailored to the individual, and including a motivational component, need to be included as integral components of management to reduce cardiovascular and metabolic risk factors more effectively in this group.

OSA (obstructive sleep apnoea) stimulates sympathetic nervous activity and elevates resting HR (heart rate) and BP (blood pressure). In the present study in a cohort of 309 untreated OSA patients, the resting HR and BP during the daytime were correlated with AHI (apnoea/hypopnea index) and compared with patients with R389R (n=162), R389G (n=125) and G389G (n=22) genotypes of the β1-adrenoreceptor R389G polymorphism. We analysed the impact of the genotype on the decline of HR and BP in a subgroup of 148 patients (R389R, n=86; R389G, n=54; G389G, n=8) during a 6-month follow-up period under CPAP (continuous positive airway pressure) therapy during which cardiovascular medication remained unchanged. In untreated OSA patients, we found an independent relationship between AHI and resting HR (β=0.096, P<0.001), systolic BP (β=0.09, P=0.021) and diastolic BP (β=0.059, P=0.016). The resting HR/BP, however, did not differ among carriers with the R389R, R389G and G389G genotypes. CPAP therapy significantly reduced HR [−2.5 (−1.1 to −4.0) beats/min; values are mean difference (95% confidence intervals)] and diastolic BP [−3.2 (−1.5 to −5.0) mmHg]. The decline in HR was more significantly pronounced in the R389R group compared with the Gly389 carriers [−4.1 (−2.3 to −5.9) beats/min (P<0.001) compared with −0.2 (2.1 to −2.6) beats/min (P=0.854) respectively; Student's t test between groups, P=0.008]. Diastolic BP was decreased significantly (P<0.001) only in Gly389 carriers (R389G or G389G) compared with R389R carriers [−5.0 (−2.3 to −7.6) mmHg compared with −2.0 (0.4 to −4.3) mmHg respectively]. ANOVA revealed a significant difference (P=0.023) in HR reduction between the three genotypes [−4.1 (±8.4) beats/min for R389R, −0.5 (±9.3) beats/min for R389G and +1.9 (±7.2) beats/min for G389G]. In conclusion, although the R389G polymorphism of the β1-adrenoceptor gene did not influence resting HR or BP in untreated OSA patients, it may modify the beneficial effects of CPAP therapy on these parameters.

RationaleApproximately 60% of the patients with obstructive sleep apnoea suffer from a positional effect, and approximately 25% of these patients present events only in the supine position.ObjectiveTo validate a new positional vibrating device and evaluate its efficacy in reducing the Apnoea–Hypopnoea Index and the total sleep time in the supine position without disturbing sleep.MethodsA total of 128 patients were recruited for this multicentre, prospective, parallel, randomised controlled trial and were distributed in three arms (general recommendations, inactive and active device). Full overnight polysomnography was performed at baseline and at 12 weeks. Anthropometric variables and sleep and quality of life questionnaires were collected at 4, 8 and 12 weeks.ResultsThe Apnoea-Hypopnoea Index decreased from 30.6 per hour to 20.4 per hour (p<0.001) in the active device (AD) group. In this group the reduction was 2.3-fold and 3.3-fold than the ones in the general recommendations (GR) and inactive device (ID) groups, respectively (p=0.014). Sleep time in supine position decreased 17.7%±26.3% in GR group (p<0.001), 13.0%±22.4% with ID group (p<0.001) and 21.0%±25.6% in the AD group (p<0.001). Furthermore, total sleep time increased significantly only in the AD group (22.1±57.5 min, p=0.016), with an increased percentage of time in the N3 (deep sleep) and N3+REM (rapid eye movement) stages, without sleep fragmentation.ConclusionThe device was effective in reducing the Apnoea–Hypopnoea Index and time spent in the supine position also in improving sleep architecture. Therefore, the device could be a good option for the management of patients with positional obstructive sleep apnoea.Trial registration detailsThe trial was registered at www.clinicaltrials.gov (NCT03336515).
