Objetivo: determinar prevalência de rastreamento positivo para SAHOS e identificar fatores associados em hipertensos em serviço de Atenção Primária à Saúde (APS). Métodos: estudo transversal com 326 hipertensos adscritos a uma unidade de APS. Foram obtidas variáveis antropométricas, clínicas e sociodemográficas e utilizados os questionários Short Assessment of Health Literacy for Portuguese-Speaking Adults, para identificar o letramento em saúde; a Morisky Medication Adherence Scale, para a adesão medicamentosa e o Snoring, Tiredness, Observed Apnea, High Blood Pressure, Bodymass index, Age, Neck Circumference, and Gender -STOP-Bang, para rastreamentoda SAHOS. Resultados: o sexo feminino foi majoritário (66,3%). A média temporal de tratamento para hipertensão arterial sistêmica alcançou 12,51 ± 9,83 anos. Constatou-se prevalência de 86,5% de rastreio positivo para SAHOS e o sexo masculino e a obesidade como fatores associados a essa condição (p<0,01). Conclusão: o rastreamento sistemático da SAHOS na APS deve ser incorporado à prática dos profissionais de saúde, assim como é feito para outras doenças crônicas não transmissíveis 1.


Introduction: Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is the most common sleep breathing disorder, associated with easily identifiable conditions such as systemic arterial hypertension. Objective: To determine the prevalence of positive screening for Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) and to identify associated factors in the hypertensive population in the Primary Health Care (PHC) service. Method: This was a cross-sectional study with 326 hypertensive individuals assigned to a PHC unit in a medium-sized city in the state of Minas Gerais. Anthropometric, clinical, and sociodemographic variables were obtained. The Short Assessment of Health Literacy for Portuguese-Speaking Adults questionnaire was used to identify literacy in health; the Morisky Medication Adherence Scale was used for medication adherence; and the Snoring, Tiredness, Observed Apnea, High Blood Pressure, Body Mass Index, Age, Neck Circumference, and Gender -STOP-Bang questionnaire was used for the screening of OSAHS. Results: The majority was female (66.3%) and the treatment time average for high blood pressure was 12.51 ± 9.83 years. The study identified the prevalence of 86.5% of positive screening for OSAHS, and male sex and obesity as factors associated with this condition (p <0.01). Conclusion: The systematic screening of OSAHS in PHC services should be incorporated into the practice of health professionals, as itis done for other chronic non-communicable diseases.

ABSTRACT

Resumo Fundamento Aparentemente, a pior resposta a algumas classes de anti-hipertensivos, especialmente inibidores da enzima conversora da angiotensina e bloqueadores de receptor de angiotensina, pela população negra, explicaria, pelo menos parcialmente, o pior controle da hipertensão entre esses indivíduos. Entretanto, a maioria das evidências vêm de estudos norte-americanos. Objetivos Este estudo tem o objetivo de investigar a associação entre raça/cor da pele autorrelatadas e controle de PA em participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil) utilizando várias classes de anti-hipertensivos em monoterapia. Métodos O estudo envolveu uma análise transversal, realizada com participantes da linha de base do ELSA-Brasil. O controle de pressão arterial foi a variável de resposta, participantes com valores de PA ≥140/90 mmHg foram considerados descontrolados em relação aos níveis de pressão arterial. A raça/cor da pele foi autorrelatada (branco, pardo, negro). Todos os participantes tiveram que responder perguntas sobre uso contínuo de medicamentos. A associação entre o controle de PA e raça/cor da pele foi estimada por regressão logística. O nível de significância adotado nesse estudo foi de 5%. Resultados Do total de 1.795 usuários de anti-hipertensivos em monoterapia na linha de base, 55,5% se declararam brancos, 27,9%, pardos e 16,7%, negros. Mesmo depois de padronizar em relação a variáveis de confusão, negros em uso de inibidores da enzima conversora de angiotensina (IECA), bloqueadores de receptor de angiotensina (BRA), diuréticos tiazídicos (DIU tiazídicos) e betabloqueadores (BB) in monoterapia tinham controle de pressão arterial pior em comparação a brancos. Conclusões Os resultados deste estudo sugerem que, nesta amostra de brasileiros adultos utilizando anti-hipertensivos em monoterapia, as diferenças de controle de pressão arterial entre os vários grupos raciais não são explicadas pela possível eficácia mais baixa dos IECA e BRA em indivíduos negros.


Abstract Background It seems that the worst response to some classes of antihypertensive drugs, especially angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, on the part of the Black population, would at least partially explain the worse control of hypertension among these individuals. However, most of the evidence comes from American studies. Objectives This study aims to investigate the association between self-reported race/skin color and BP control in participants of the Longitudinal Study of Adult Health (ELSA-Brasil), using different classes of antihypertensive drugs in monotherapy. Methods The study involved a cross-sectional analysis, carried out with participants from the baseline of ELSA-Brasil. Blood pressure control was the response variable, participants with BP values ≥140/90 mmHg were considered out of control in relation to blood pressure levels. Race/skin color was self-reported (White, Brown, Black). All participants were asked about the continuous use of medication. Association between BP control and race/skin color was estimated through logistic regression. The level of significance adopted in this study was of 5%. Results Of the total of 1,795 users of antihypertensive drugs in monotherapy at baseline, 55.5% declared themselves White, 27.9% Brown, and 16.7% Black. Even after adjusting for confounding variables, Blacks using angiotensin converting enzyme inhibitors (ACEI), angiotensin receptor blocker (ARB), thiazide diuretics (thiazide DIU), and beta-blockers (BB) in monotherapy had worse blood pressure control compared to Whites. Conclusions Our results suggest that in this sample of Brazilian adults using antihypertensive drugs in monotherapy, the differences in blood pressure control between different racial groups are not explained by the possible lower effectiveness of ACEIs and ARBs in Black individuals.

ABSTRACT

Abstract Objective: In this study, the authors aimed to evaluate the effectiveness of the vena cava distensibility index and pulse pressure variation as dynamic parameters for estimating intravascular volume in critically ill children. Methods: Patients aged 1 month to 18 years, who were hospitalized in the present study's pediatric intensive care unit, were included in the study. The patients were divided into two groups according to central venous pressure: hypovolemic (< 8mmHg) and non-hypovolemic (central venous pressure ≥ 8 mmHg) groups. In both groups, vena cava distensibility index was measured using bedside ultrasound and pulse pressure variation. Measurements were recorded and evaluated under arterial monitoring. Results: In total, 19 (47.5%) of the 40 subjects included in the study were assigned to the central venous pressure ≥ 8 mmHg group, and 21 (52.5%) to the central venous pressure < 8 mmHg group. A moderate positive correlation was found between pulse pressure variation and vena cava distensibility index (r = 0.475, p < 0.01), while there were strong negative correlations of central venous pressure with pulse pressure variation and vena cava distensibility index (r = -0.628, p < 0.001 and r = -0.760, p < 0.001, respectively). In terms of predicting hypovolemia, the predictive power for vena cava distensibility index was > 16% (sensitivity, 90.5%; specificity, 94.7%) and that for pulse pressure variation was > 14% (sensitivity, 71.4%; specificity, 89.5%). Conclusion: Vena cava distensibility index has higher sensitivity and specificity than pulse pressure variation for estimating intravascular volume, along with the advantage of non-invasive bedside application.

ABSTRACT

Abstract Objectives: Dexmedetomidine (DEX) is a highly selective alpha-2 adrenergic receptor agonist, which is the main sedative in the intensive care unit. This study aims to investigate the effectiveness and adverse events of DEX in maintaining hemodynamic stability in pediatric cardiac surgery. Sources: Databases such as PubMed, Cochrane, Web of Science, WANFANG STATA and China National Knowledge Infrastructure were searched for articles about the application of DEX in maintaining hemodynamic stability during and after pediatric cardiac surgery up to 18th Feb. 2021. Only randomized controlled trials were included and random-effects model meta-analysis was applied to calculate the standardized mean deviation (SMD), odds ratio (OR) and 95% confidence interval (CI). Summary of the findings: Fifteen articles were included for this meta-analysis, and 9 articles for qualitative analysis. The results showed that preoperative prophylaxis and postoperative recovery of DEX in pediatric patients undergoing cardiac surgery were effective in maintaining systolic blood pressure (SBP), mean arterial pressure (MAP), diastolic blood pressure (DBP) and reducing heart rate (HR) (SBP: SMD = -0.35,95% CI: -0.72, 0.01; MAP: SMD = -0.83, 95% CI: -1.87,0.21; DBP: SMD = -0.79,95% CI: -1.66,0.08; HR: SMD = -1.71,95% CI: -2.29, -1.13). In addition, the frequency of Junctional Ectopic Tachycardia in the DEX treatment group was lower than that in the placebo group. Conclusions: The application of DEX for preoperative prophylaxis and postoperative recovery in pediatric cardiac surgery patients are effective in maintaining hemodynamic stability, and the clinical dose of DEX is not significantly related to the occurrence of pediatric adverse events which may be related to individual differences.

ABSTRACT

The Chilean workforce has over 200,000 people that are intermittently exposed to altitudes over 4000 m. In 2012, the Ministry of Health provided a technical guide for high altitude workers that included a series of actions to mitigate the effects of hypoxia. Previous studies have shown the positive effect of oxygen enrichment at high altitudes. The Atacama Large Millimeter / submillimeter Arrays (ALMA) radiotelescope operate at 5,050 m (Array Operation Site, AOS) and is the only place in the world where Pressure Swing Adsorption (PSA) and Liquid Oxygen technologies have been installed at a large scale. Here we discuss our experience using oxygen supplementation at ALMA, to prevent the malaise and/or risks associated with exposure at 5,050 m. Antenna operators experienced chronic intermittent hypobaric hypoxia (CIHH, shiftwork 8 days HA*6 days rest SL) over 4 years. Studies to define normal O2 saturation values were performed in OSF and AOS by continuous recording during the shift. The outcomes showed no differences between production procedures (PSA or Liquid oxygen) in regulating oxygen availability at AOS facilities. As a result, big-scale installations have difficulties reaching the appropriate oxygen concentration due to leaks in high mobility areas. In addition, the PSA plant requires adequation and maintenance to operate at a very high altitude.


La fuerza laboral chilena cuenta con más de 200.000 personas que están expuestas intermitentemente a altitudes superiores a los 4000 m. En 2012, el Ministerio de Salud entregó una guía técnica para trabajadores de altura que incluía una serie de acciones para mitigar los efectos de la hipoxia. Estudios anteriores han demostrado el efecto positivo del enriquecimiento de oxígeno en altitudes elevadas. El radiotelescopio Atacama Large Millimeter/submillimeter Arrays (ALMA) opera a 5.050 m (Array Operation Site, AOS) y es el único lugar en el mundo donde se han instalado tecnologías de adsorción por cambio de presión (PSA) y oxígeno líquido a gran escala. Aquí discutimos nuestra experiencia usando suplementos de oxígeno en ALMA, para prevenir el malestar y/o los riesgos asociados con la exposición a 5.050 m. Los operadores de antena experimentaron hipoxia hipobárica intermitente crónica (CIHH, trabajo por turnos 8 días HA*6 días descanso SL) durante 4 años. Se realizaron estudios para definir valores normales de saturación de O2 en OSF y AOS mediante registro continuo durante el turno. Los resultados no mostraron diferencias entre los procedimientos de producción (PSA u oxígeno líquido) en la regulación de la disponibilidad de oxígeno en las instalaciones de AOS. Como resultado, las instalaciones a gran escala tienen dificultades para alcanzar la concentración de oxígeno adecuada debido a fugas en áreas de alta movilidad. Además, la planta de PSA requiere de adecuación y mantenimiento para operar a gran altura.

ABSTRACT

SUMMARY OBJECTIVE: The objective of this study was to analyze the association between orthostatic changes in blood pressure and mortality in elderly cardiopath patients. METHODS: A cohort of 455 elderly cardiopath patients, monitored at a referral outpatient cardiology clinic in Pernambuco, Brazil, from October 2015 to July 2018. The exposure groups were formed according to their orthostatic changes in blood pressure following the requirements of the Brazilian Guidelines for Hypertension. RESULTS: Orthostatic hypotension was present in 46 patients (10.1%), 91 had orthostatic hypertension (20%), and 318 had no orthostatic alterations (69.9%). There were 52 deaths during follow-up. The results demonstrated that there was no statistically significant association between orthostatic hypotension and overall mortality (HR 1.30; 95%CI 0.53-3.14; p=0.567) nor between orthostatic hypertension and overall mortality (HR 0.95; 95%CI 0.65-1.39; p=0.34). Survival in relation to the exposure groups presented no statistically significant difference (p=0.504). CONCLUSION: There was a low frequency of orthostatic hypotension and a mild high frequency of orthostatic hypertension when compared with previous studies, and no association was observed with overall mortality or with the survival time of elderly patients with heart disease.

ABSTRACT

According to different researches, 30% of university graduates have a low level of health, and studying at university is one of the factors of its deterioration, besides the first year is considered critical. The purpose of research is to study the dynamics of physical development, physical fitness and functional state of young men during the first year of university studies. For the survey we used standard measurements and index calculations for 11 indicators of physical development, 9 indicators of physical fitness and 15 indicators of functional status. We calculated the arithmetic mean (M), the standard error of the mean (m), then evaluated differences by the Student criterion (t) for independent samples and considered them as reliable atр < 0.05. It is shown that during the first year of studies, young men have an increase in the Erismann index, the corpulence (Rohrer's) index, the body mass index and a decrease in the Pignet index. There is also an increase in the coefficient of endurance, adaptive capacity and diastolic pressure, while vital capacity of the lungs, the vital index, time of hanging on the bar and the speed of running 1000 m decrease. The dynamics of physical development is expressed in a change in mass-growth indices and indicates an increase in body weight. The dynamics of physical fitness is expressed in a decrease of the time of hanging on the bar and the speed of running 1000 m. The dynamics of the functional state is expressed in a decrease of vital capacity of the lungs, vital index, increase in the coefficient of endurance, adaptive capacity and diastolic blood pressure.

ABSTRACT

OBJECTIVE@#To explore the role of interleukin-17A (IL-17A) in renal epithelial- mesenchymal transition (EMT) in essential hypertensive nephropathy.@*METHODS@#Four-week-old spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats (control group) were both randomized into 4 groups (n=5) for observation at 4, 6, 10 and 30 weeks of age. Blood pressure of the rats was monitored using a noninvasive tail artery blood pressure measurement instrument. The percentage of Th17 cells in the splenocytes was analyzed using flow cytometry. The mRNA and protein expression levels of IL-17A, iNOS, Arg-1, E-cadherin, and α-SMA in the kidneys of the rats were detected using RT-PCR and immunohistochemical staining, respectively, and plasma levels of IL-17A were regularly detected using ELISA.@*RESULTS@#At the age of 6 weeks, the SHRs began to show significantly higher blood pressure with greater Th17 cell percentage in the splenocytes and high renal expression and plasma level of IL-17A than WKY rats (P < 0.05 or P < 0.01). At 30 weeks, renal expression of E-cadherin mRNA and protein was significantly lower and the expression of Arg-1 mRNA and protein was significantly higher in SHR than in WKY rats (P < 0.01). Compared with the WKY rats, the SHRs showed significantly higher mRNA and protein expressions of iNOS at 6 and 10 weeks (P < 0.05 or 0.01) and higher α-SMA mRNA and protein expressions since 10 weeks of age (P < 0.05 or 0.01). In SHRs older than 10 weeks, renal IL-17A mRNA and protein expression levels were negatively correlated with those of E-cadherin (r=-0.731, P < 0.05; r=-0.827, P < 0.01) and positively correlated with those of α-SMA (r=0.658, P < 0.05; r=0.968, P < 0.01).@*CONCLUSION@#IL-17A is closely correlated with the progression of renal EMT in SHR and plays its role possibly by mediating M1/M2 polarization of renal infiltrating macrophages.

ABSTRACT

This cross-sectional study aimed to investigate the quality of care of diabetes in Shanghai, China. A total of 173 235 patients with type 2 diabetes in 2017 were included in the analysis. Profiles of risk factors and intermediate outcomes were determined. The patients had a mean age of 66.43 ± 8.12 (standard deviation (SD)) years and a mean diabetes duration of 7.95 ± 5.53 (SD) years. The percentage of patients who achieved the target level for HbA1c (< 7.0%) was 48.6%. Patients who achieved the target levels for blood pressure (BP) < 130/80 mmHg and low-density lipoprotein-cholesterol (LDL-c) < 2.6 mmol/L reached 17.5% and 34.0%, respectively. A total of 3.8% achieved all three target levels, and the value increased to 6.8% with an adaptation of the BP target level (< 140/90 mmHg) for those over 65 years. Multivariable analysis identified the factors associated with a great likelihood of achieving all three target levels: male, young age, short diabetes duration, low body mass index, macrovascular complications, no microvascular complications, prescribed with lipid-lowering medication, and no prescription of antihypertensive medication. In conclusion, nearly 50% and one-third of the patients with diabetes met the target levels for HbA1c and LDL-c, respectively, with a low percentage achieving the BP target level. The percentage of patients who achieved all three target levels needs significant improvement.

ABSTRACT

Objective: To investigate the clinical value of coefficient of variation of heart rate and blood pressure in rapid identification of children with suspected orthostatic intolerance(OI). Methods: This was a retrospective study. The medical records of 379 children with OI were collected, who were admitted to the Department of Pediatrics of Qilu Hospital of Shandong University from January 2015 to January 2020. Another 20 out-patient children without syncope or syncope aura were selected as control. According to the results of standing test and head-up tilt test (HUTT), all the patients with OI were divided into the following 4 groups: vasovagal syncope (VVS) group, postural tachycardia syndrome (POTS) group, POTS combined with VVS (POTS+VVS) group and HUTT negative group. Then, coefficient of variation of systolic pressure (SBPCV), coefficient of variation of diastolic pressure (DBPCV) and coefficient of variation of heart rate (HRCV) in standing test and HUTT were calculated. Kruskal-Wallis test was used for comparison among the five groups, and Dunnett's T3 method for comparison between two groups. Paired t test was used to compare the coefficient of variation between supine and erect position and tilt position in each group. The predictive values of HRCV,SBPCV and DBPCV for negative HUTT were evaluated by receiver operating characteristic (ROC) curve. Results: Among the 379 children, there were 79 in HUTT negative group, 208 in VVS group, 52 in POTS group, and 40 in POTS+VVS group. The SBPCV of supine-erect position of the control group, HUTT negative group, VVS group, POTS group, POTS+VVS group were (3.8±1.0)%, (5.3±2.2)%, (6.6±3.4)%, (5.9±3.6)%, (6.9±2.8)%, respectively. Similarly, the SBPCV of supine, erect and head-up tilt position were (4.5±0.8)%, (6.0±1.9)%, (7.1±2.6)%, (6.0±2.1)%, (7.3±2.5)%; the DBPCV of supine-erect position were (7.3±1.2)%, (9.1±3.7)%, (9.1±4.9)%, (9.1±4.8)%, (11.6±4.6)%; the DBPCV of supine, erect and tilt position were (7.4±1.1)%, (9.4±2.9)%, (10.1±3.8)%, (9.2±3.3)%, (11.0±4.7)%; the HRCV of supine-erect position were (7.6±2.6)%, (12.9±3.7)%, (16.2±4.3)%, (21.2±5.9)%, (24.9±5.3)%; and the HRCV of supine, erect and tilt position were (8.1±1.6)%, (10.1±2.7)%, (14.1±4.3)%, (15.6±3.7)%, (18.9±4.0)%, respectively. All the indexes showed significant differences among the five groups (χ2=21.91, 25.47, 19.82, 14.65, 104.52, 92.51, all P<0.05). ROC curve analysis showed that when the SBPCV and HRCV of supine-erect position reached 4.4% and 10.5%, the area under the curve of ROC were 0.713 and 0.877, the sensitivity of predicting negative HUTT were 58.2% and 78.5%, and the specificity were 80.0% and 95.0%, respectively. Conclusions: Coefficient of variation of heart rate and blood pressure may serve as potential diagnostic indexes in evaluating autonomic function of OI patients. SBPCV ≥ 4.4% or HRCV ≥ 10.5% of supine-erect position could be an indication of HUTT.

ABSTRACT

Objective: Predictive models were used to evaluate the impact of common risk factors on the number of cardio-cerebrovascular deaths and the probability of premature death. Methods: Using the data for China estimated by the Global Burden of Disease study 2015 (GBD 2015), we calculated the population attribution fraction (PAF) of risk factors. The proportional change model was used to estimate the number of unattributable deaths by 2030, and to predict the number of deaths, mortality, standardized mortality and probability of premature death by 2030. Results: According to the natural change trend of risk factors from 1990 to 2015, the number of deaths and mortality would reach 6.12 million and 428.53/100 000 by 2030, with an increase of 59.92% and 52.87%. By 2030, the probability of premature death from cardio-cerebrovascular diseases among Chinese aged 30-70 years old would continue to decline, from 11.43% to 11.28% for men, and from 5.79% to 4.43% for women. If the goals of all included risk factors were reached by 2030, 2 289 200 cardio-cerebrovascular deaths would be avoided. If only the exposure to a single risk factor was achieved by 2030, blood pressure, total cholesterol, and fine particulate matter exposure were the three most important factors affecting cardio-cerebrovascular deaths, which would reduce 1 332 800, 609 100 and 306 800 deaths, respectively. Among the involved risk factors, the control of blood pressure would mostly decrease the number of deaths due to ischemic heart disease and hemorrhagic stroke, about 677 300 and 391 100 deaths, accordingly. Conclusion: The control of risk factors is of great significance in reducing deaths and probability of premature death due to cardio-cerebrovascular diseases. If the control targets of all risk factors could be achieved by 2030, the burden of cardio-cerebrovascular diseases would be reduced greatly.

ABSTRACT

Mercury sphygmomanometer based on traditional auscultation method is widely used in primary medical institutions in China, but a large amount of blood pressure data can not be directly recorded and applied in scientific research analysis, meanwhile auscultation data is the clinical standard to verify the accuracy of non-invasive electronic sphygmomanometer. Focusing on this, we designed a miniature non-invasive blood pressure measurement and verification system, which can assist doctors to record blood pressure data automatically during the process of auscultation. Through the data playback function,the software of this system can evaluate and verify the blood pressure algorithm of oscillographic method, and then continuously modify the algorithm to improve the measurement accuracy. This study introduces the hardware selection and software design process in detail. The test results show that the system meets the requirements of relevant standards and has a good application prospect.

ABSTRACT

With the implementation of the new policy for coronary stent centralized volume purchasing in China, the blood pressure sensor at the tip of the catheter, as one of the essential medical instruments for the diagnosis and treatment of coronary artery disease, will meet the new development opportunity of the industry, a number of medical device companies will actively participate in the development and registration of the catheter tip blood pressure sensor. As an invasive blood pressure sensor, the catheter tip blood pressure sensor should meet the current effective industry standard YY 0781-2010, however, there are many problems when using YY 0781-2010 as a blood pressure sensor because of the difference of product structure and working mode. In this paper, the problems about "Operation Manual", "electrical performance" and "safety requirement" in the course of carrying out YY 0781- 2010 with the blood pressure sensor on the tip of catheter are discussed and analyzed in detail, hope to provide some inspiration for more research and development enterprises of blood pressure sensors on the tip of catheters and inspectors of medical device testing institutions, also hope to be able to contribute to the high-quality development of blood pressure sensor industry at the tip of the Catheter.

ABSTRACT

Sleep apnea causes cardiac arrest, sleep rhythm disorders, nocturnal hypoxia and abnormal blood pressure fluctuations in patients, which eventually lead to nocturnal target organ damage in hypertensive patients. The incidence of obstructive sleep apnea hypopnea syndrome (OSAHS) is extremely high, which seriously affects the physical and mental health of patients. This study attempts to extract features associated with OSAHS from 24-hour ambulatory blood pressure data and identify OSAHS by machine learning models for the differential diagnosis of this disease. The study data were obtained from ambulatory blood pressure examination data of 339 patients collected in outpatient clinics of the Chinese PLA General Hospital from December 2018 to December 2019, including 115 patients with OSAHS diagnosed by polysomnography (PSG) and 224 patients with non-OSAHS. Based on the characteristics of clinical changes of blood pressure in OSAHS patients, feature extraction rules were defined and algorithms were developed to extract features, while logistic regression and lightGBM models were then used to classify and predict the disease. The results showed that the identification accuracy of the lightGBM model trained in this study was 80.0%, precision was 82.9%, recall was 72.5%, and the area under the working characteristic curve (AUC) of the subjects was 0.906. The defined ambulatory blood pressure features could be effectively used for identifying OSAHS. This study provides a new idea and method for OSAHS screening.
