The goal of this study is to evaluate the effectiveness of Nursing Consultation based on the assumptions and techniques of Motivational Interviewing for the control of Type 2 diabetes mellitus with associated diagnosis of Systemic Arterial Hypertension in primary healthcare.

The recently published LA Barbershop in the New England Journal of Medicine (Victor et al. N Engl J Med 2018; 378: 1291-301) solid evidence of the efficacy of a pharmacist-led medication management intervention to reduce blood pressure in black men that patronize barbershops. One of the most significant logistical inefficiencies of the LA Barbershop Study was the amount of time the pharmacists spent driving for face-to-face visits with participants. On average, each round trip was 40 miles and pharmacists drove 2 hours per day. By using telemedicine, the study team can minimize the number of face-to-face in-person visits and increase pharmacist efficiency by 25%. the study team aim to increase the scalability of our novel, evidence-based barbershop model by addressing this inefficiency with the pilot study. In the LA Barbershop trial, each participant averaged 7 in-person visits in 6 months. the study team found that the initial in-person visits between the pharmacist, barber, and patron were essential for establishing trust as well as obtaining baseline electrolyte and serum creatinine levels (with our validated point-of-care device, iSTAT). However, once rapport has been established and blood pressure control achieved, the study team postulate that the effect can be maintained remotely with telemedicine. Our data indicate that most patients' can achieve their blood pressure goal in 3 months or less. the study team propose replacing additional in-person visits with telemonitoring (via Skype or FaceTime) at this juncture, provided blood chemistries are stable. the study team plan to pilot this in 20 patients from 2 to 3 barbershops for 12 months.

This Study evaluates the effect of 20 weeks of isometric handgrip (IHG) home training in adults aged 50 years or more. Half of the participants will serve as a control group and will only receive hypertension-guidelines on lifestyle changes.

Background: Depression is a common comorbidity of physical chronic diseases such as diabetes and/or hypertension and constitutes an important public health problem. It correlates negatively with the patients' quality of life and self-care, as well as compliance with medical treatment. In low- and middle-income countries depression often goes unrecognized and untreated, and there are limited human resources to treat depression and other mental problems. Aim: The present study aims to test a 6-week low-intensity psychological intervention (CONEMO - CONtrol EMOcional) delivered by a smartphone application to people with depressive symptoms and co-morbid diabetes and/or hypertension recruited in primary health care centers and public hospitals in Lima, Peru.

To explore the beneficial effects of 'empagliflozin + ARB' in comparison with 'placebo + ARB' on the reduction of nocturnal blood pressure in T2DM with hypertension

The most common co-morbidity accompanying Chronic Kidney Disease (CKD) is hypertension, which appears in approximately 80% of all patients with renal dysfunction, whereas its prevalence in general population is remarkably lower appearing in approximately 30% of adults.Defining hypertension in ESRD patients under maintenance dialysis is a challenging procedure. Ambulatory blood pressure monitoring (ABPM) is considered the "gold standard" for the diagnosis of hypertension in hemodialysis patients over the last years. The major pathophysiologic mechanism underlying hypertension development in patients with ESRD under hemodialysis is water and sodium overload. Identifying an accurate and objective method of dry weight evaluation has been a matter of intensive nephrology research for more than two decades. Assessment of the water balance in hemodialysis patients on the basis of common clinical criteria (e.g. leg or face swelling or signs of lung congestion) is a subjective method with limited reliability, despite its widespread use. Recently, a novel technique has been developed to quantify water excess by conducting an ultrasound lung scan. Pilot studies have shown significant changes in lung water in hemodialysis patients according to body weight changes during interdialytic days and dialysis sessions. Moreover, results from previous studies indicate significant benefits from dry weight probing with regards to blood pressure (BP). The clinical application of a lung-ultrasound-based volume control strategy in hemodialysis patients is currently being tested by the randomized study entitled "Lung water by ultrasound guided treatment to prevent death and cardiovascular complications in high risk end stage renal disease patients with cardiomyopathy (The LUST Study)". This clinical trial aims at evaluating whether the use of the number of US-B lines could be used as a biomarker to guide a per-protocol intensification of ultrafiltration (UF) in order to reduce volume overload, improve cardiac function and prolong survival. Cardiovascular disease in patients with CKD is attributed to a spectrum of structural and functional alterations of the large and the small branches of the arterial tree. The most important process in patients with advanced CKD is that of arteriosclerosis, which is developed in parallel to atherosclerosis and is typically associated with impaired cushioning function of the aorta and the large conduit arteries. Accelerated arterial stiffening is involved in the development of isolated systolic hypertension, left ventricular hypertrophy (LVH) and congestive heart failure (CHF), which predispose to arrhythmias and sudden cardiac death. In the context of the phenomenon of "aortic-to-brachial BP amplification", systolic BP (SBP) and pulse pressure (PP) conventionally measured at the level of brachial artery are higher than the relevant pressures in the ascending aorta. Due to extreme elevation of arterial stiffness, BP amplification is disturbed in patients with ESRD. Prospective cohort studies have demonstrated that elevated central PP, wave reflections and arterial stiffness, as well as, reduced PP amplification represent strong and independent predictors of all-cause and cardiovascular mortality in hemodialysis patients. On this basis, estimation of central BP indices appears as an important tool towards optimisation of cardiovascular risk stratification in ESRD as well as in other diseased populations. Until recently, available devices for ABPM evaluated BP levels only at the level of brachial artery. The newly developed Mobil-O-Graph NG (IEM, Stolberg, Germany) provides the ability to monitor central aortic pressure and indices of vascular resistance, such as wave reflections (augmentation index, AIx) and arterial stiffness (pulse wave velocity, PWV).This device has recently been validated in hemodialysis patients and showed comparable performance with the widely used tonometric SphygmoCor device (ArtCor, Sydney, Australia). Accumulated evidence over central BP and PWV in hemodialysis patients derives mostly from studies that included only static pre-dialysis and post-dialysis measurements. However, variations of BP levels during intra- and interdialytic intervals combined with the superiority of aortic BP measurements, as analysed above, indicate that ambulatory monitoring of central BP is the best available method. This study aims for the first time to evaluate the outcome of a treatment strategy for dry weight probing, based on volume overload quantification with lung ultrasound, on 48-hour peripheral systolic BP, aortic BP and arterial stiffness in hemodialysis hypertensive patients. This is a Lust Sub-Study. Additional information can be found at: NCT02310061.

This study aims to evaluate whether NSAIDs (Non-steroidal antiinflammatory drugs) administered during the postpartum period influence blood pressure in women with hypertensive disorders of pregnancy. The study design is a prospective double blinded randomized control trial with participants randomized to receive postpartum analgesic regimens with and without NSAIDs.

Aim: To evaluate the effects of Valsartan versus Amlodipine on LV deformation in relation to plasma adiponectin and leptin levels in hypertensive individuals. Methods: LV strain measured by 2 dimensional speckle tracking echocardiography, plasma levels of adiponectin and leptin was determined in 30 healthy individuals served as control group and in 200 hypertensive patients before and after treatment for three months with either Valsartan 160 mg or amlodipine 10 mg.

Obstructive sleep apnea syndrome (OSA) is the most frequent sleep disorder characterized by excessive decrease in muscle tone of the soft palate, the tongue and the posterior pharyngeal wall. It leads to airway collapse. In cases of decreased airway passage hypoventilation (hypopnea) occurs while periodic lack of airflow is called apnea. An obstructive sleep apnea syndrome is recognized as an independent cardiovascular risk factor. OSA is very common in patients with resistant hypertension. RAH is diagnosed when blood pressure remains elevated despite simultaneous use of 3 antihypertensive agents from different groups of drugs at optimal to maximum doses, including a diuretic. In patients with OSA frequent episodes of hypoxemia during sleep result in the repeated activation of the sympathetic nervous system. What is more, the episodes of respiratory disorders increases in levels of aldosterone serum concentration with following sodium and water retention and elevation of blood pressure finally. An increased aldosterone level also stimulates synthesis of collagen, promotes stiffening of the arterial wall, myocardial fibrosis with heart muscle remodeling and takes part in development of left ventricular hypertrophy (LVH) - common complication of hypertensive patients with OSA. Several studies, including the Sleep Heart Health Study have confirmed that severe OSA is associated with high prevalence of concentric hypertrophy through sympathetic activation and vasoconstriction. Eplerenone is a selective mineralocorticoid receptor inhibitor. It has no affinity for glucocorticoid, progesterone and androgen receptors and therefore has lower risk of side effects. Eplerenone lowers blood pressure and inhibits heart muscle fibrosis. The hypotensive effect is caused by reduction of fluid retention. Probably, in patients with OSA, a reduction of fluid accumulation especially at the level of the neck may contribute to lowering the resistance in the upper respiratory tract and in that way it may help to decrease the severity of OSA. As LVH remains a strong and independent predictor of total mortality and death from cardiovascular causes, in this study we want to assess whether the addition of Eplerenone to a standard antihypertensive therapy will favorably change left ventricular geometry. We also want to check if the addition the Eplerenone to a standard antihypertensive therapy could be an effective therapeutic option for patients with OSA and RAH.

The study will evaluate the effect of trimetazidine versus placebo in addition to standard pulmonary arterial hypertension regime on right ventricular function in pulmonary arterial hypertension patients.
