This paper presents a cuff-less hypertension pre-screening device that non-invasively monitors the Blood Pressure (BP) and Heart Rate (HR) continuously. The proposed device simultaneously records two clinically significant and highly correlated biomedical signals, viz., Electrocardiogram (ECG) and Photoplethysmogram (PPG). The device provides a common data acquisition platform that can interface with PC/laptop, Smart phone/tablet and Raspberry-pi etc. The hardware stores and processes the recorded ECG and PPG in order to extract the real-time BP and HR using kernel regression approach...

INTRODUCTION: Uncontrolled hypertension is largely attributed to unsatisfactory doctor's engagement in its optimal management and to poor patients' compliance to therapeutic interventions. ICT and mobile Health solutions might improve these conditions, being widely available and providing highly effective communication strategies. OBJECTIVE: To evaluate whether ICT and mobile Health tools are able to improve hypertension control by improving doctors' engagement and by increasing patients' education and involvement, and their compliance to lifestyle modification and prescribed drug therapy...

AIMS: There is a need for alternative strategies that might avoid recurrent admissions in patients with heart failure. home telemonitoring (HTM) to monitor patient's symptoms from a distance may be useful. This study attempts to assess changes in HTM vital signs in response to daily life activities (variations in medication, salt intake, exercise, and stress) and to establish which variations affect weight, blood pressure, and heart rate. METHODS AND RESULTS: We assessed 76 patients with heart failure (mean age 76 ± 10...

BACKGROUND AND OBJECTIVES: In home-based context-aware monitoring patient's real-time data of multiple vital signs (e.g. heart rate, blood pressure) are continuously generated from wearable sensors. The changes in such vital parameters are highly correlated. They are also patient-centric and can be either recurrent or can fluctuate. The objective of this study is to develop an intelligent method for personalized monitoring and clinical decision support through early estimation of patient-specific vital sign values, and prediction of anomalies using the interrelation among multiple vital signs...

Blood pressure (BP) variability and nocturnal decline in blood pressure are associated with cardiovascular outcomes. However, little is known about whether these indexes are associated with white-coat and masked hypertension. We performed a cross-sectional analysis of 1047 community-dwelling individuals aged ⩾60 years in Spain in 2012. Three observer-measured home BPs and 24-h ambulatory blood pressure monitoring (ABPM) were performed under standardized conditions. BP variability was defined as BP s.d. and coefficient of variation...

BACKGROUND: Hypertension is a major risk factor for cardiovascular disease and prevalence varies by ethnic group. The diagnosis and management of blood pressure are informed by guidelines largely based on data from white populations. This study addressed whether accuracy of blood pressure measurement in terms of diagnosis of hypertension varies by ethnicity by comparing two measurement modalities (clinic blood pressure and home monitoring) with a reference standard of ambulatory BP monitoring in three ethnic groups...

This study aimed to investigate the relationship between nondipper pulse rate (PR) and hypertensive target organ damage. Ambulatory blood pressure monitoring was conducted in 940 high-risk Japanese patients enrolled in the Japan Morning Surge Home Blood Pressure Study. Nondipper PR was defined as (awake PR-sleep PR)/awake PR <0.1. The authors measured the patients' brain natriuretic peptide (BNP) and left ventricular mass index (LVMI). The nondipper PR group (n=213) had a significantly higher prevalence of high BNP (≥35 pg/mL, 39...

In patients with end-stage renal disease treated with hemodialysis or peritoneal dialysis, hypertension is very common and often poorly controlled. Blood pressure (BP) recordings obtained before or after hemodialysis display a J-shaped or U-shaped association with cardiovascular events and survival, but this most likely reflects the low accuracy of these measurements and the peculiar hemodynamic setting related with dialysis treatment. Elevated BP by home or ambulatory BP monitoring is clearly associated with shorter survival...

In this paper, we present an unobtrusive cuffless BP monitoring system based on pulse arrival time (PAT) for facilitating long-term home BP monitoring. The proposed system consists of an electrocardiograph (ECG), a photoplethysmograph (PPG), and a control circuit with a Bluetooth module, all of which are mounted on a common armchair to measure ECG and PPG signals from users while sitting on the armchair in order to calculate continuous PAT. Considering the good linear correlation of systolic BP (SBP) and the non-linear correlation of diastolic BP (DBP) with PAT, a new BP estimation method was proposed...

Blood pressure (BP) varies over 24 hours. During normal sleep, BP typically decreases by 10% or more. Research suggests that disordered sleep, particularly sleep deprivation and obstructive sleep apnea, is associated with increased BP and risk of hypertension. Less is known about the relationship between insomnia and hypertension. Population-based studies have reported an association between insomnia symptoms and both prevalent and incident hypertension, particularly in the context of short sleep duration...

BACKGROUND: The increase in life expectancy is accompanied by a growing number of elderly subjects affected by chronic comorbidities, a health issue which also implies important socioeconomic consequences. Shifting from hospital or community dwelling care towards a home personalized healthcare paradigm would promote active aging with a better quality of life, along with a reduction in healthcare-related costs. OBJECTIVE: The aim of the SMARTA project was to develop and test an innovative personal health system integrating standard sensors as well as innovative wearable and environmental sensors to allow home telemonitoring of vital parameters and detection of anomalies in daily activities, thus supporting active aging through remote healthcare...

Heart sounds (HSs) are produced by the interaction of the heart valves, great vessels, and heart wall with blood flow. Previous researchers have demonstrated that blood pressure can be predicted by exploring the features of cardiac sounds. These features include the amplitude of the HSs, the ratio of the amplitude, the systolic time interval, and the spectrum of the HSs. A single feature or combinations of several features have been used for prediction of blood pressure with moderate accuracy. Experiments were conducted with three beagles under various levels of blood pressure induced by different doses of epinephrine...

BACKGROUND: In order to achieve successful implementation an intervention needs to be acceptable and feasible to its users and must overcome barriers to behaviour change. The Person-Based Approach can help intervention developers to improve their interventions to ensure more successful implementation. This study provides an example of using the Person-Based Approach to refine a digital intervention for hypertension (HOME BP). METHODS: Our Person-Based Approach involved conducting qualitative focus groups with practice staff to explore their perceptions of HOME BP and to identify any potential barriers to implementation of the HOME BP procedures...

The rational management of hypertension (HT) inevitably starts with accurate measurement of blood pressure (BP). The recently published Systolic Blood Pressure Intervention Trial implemented automated office BP measurement. However, event-driven studies have overwhelmingly indicated that out-of-the-office BP monitoring is a prerequisite for risk stratification and for identifying the need of initiating or adjusting antihypertensive drug treatment. 24-Hour ambulatory BP monitoring is the preferred method of BP measurement and addresses major issues not covered by conventional or automated office BP measurement or home BP monitoring, such as reliably diagnosing nocturnal HT (the time window of the day during which BP is most predictive of adverse cardiovascular outcome), hypotension, or masked HT, a condition that affects 15% of the general populations and carries a risk equal to that of HT on both office and out-of-the-office BP measurement...

This Letter aims to create a fuzzy logic-based assistive prevention tool for falls, based on accessible sensory technology, such as smartwatch, resulting in monitoring of the risk factors of falls caused by orthostatic hypotension (OH); a drop in systolic blood pressure (DSBP) >20 mmHg due to postural changes. Epidemiological studies have shown that OH is a high risk factor for falls and has a strong impact in quality of life (QoL) of the elderly's, especially for some cases such as Parkinsonians. Based on smartwatch data, it is explored here how statistical features of heart rate variability (HRV) can lead to DSBP prediction and estimation of the risk of fall...

OBJECTIVE: Home blood pressure (BP) monitoring is one of the tools recommended in hypertension management. However, its influence in older adults is seldom investigated. We aimed to assess whether regular home BP monitoring leads to a reduction of BP and an improvement in hypertension control in older adults. METHODS: In a 24-month trial, individuals aged 73-97 years were randomized in a control (office and home BP measured at 0, 12, and 24 months) or an intervention (office measured at 0, 12, and 24 months; home BP measured every 3 months) group...
