Filter by:The goal of this pilot study is to effectively treat hypertension in subjects with either known or newly diagnosed hypertension and concurrent evidence of diastolic dysfunction. In patients with predominantly diastolic heart failure it is hypothesized that by using more robust echocardiographic measures of diastolic dysfunction, significant changes will be detected. Furthermore, due to the unique properties of nebivolol it is also hypothesized that there will be improvements in LV function manifesting as increased exercise capacity as well as LVH regression as measured by echocardiography. The investigators hope to reproduce the findings shown in a prior study that showed increased stroke volume and preservation of CO in subjects receiving nebivolol.
Comparison between the effect of aliskiren/amlodipine combination with amlodipine monotherapy on ankle-foot volume in hypertensive patients. It will be enrolled male or female outpatients, aged 18-65 years.
The primary objective is to evaluate the relative effectiveness of fixed CPAP in comparison to APAP in reducing arterial blood pressure in patients with resistant hypertension and obstructive sleep apnea (OSA). The secondary objectives are: a) to evaluate the relative effectiveness of fixed CPAP versus APAP in improving arterial stiffness, sleep-disordered breathing, sleep quality, inflammatory markers and glucose regulation; b) to identify specific characteristic of persons who respond to the two CPAP modalities in order to identify which device is better for each subject.
This will be a 36-week, randomized, double-blind, parallel group study comparing the effects of tadalafil monotherapy, ambrisentan monotherapy and combination therapy with tadalafil and ambrisentan in patients with PAH-SSc. Standard outcome measures such as six-minute walk distance (6MWD), NYHA classification, and hemodynamic measurements will be assessed, as well as novel functional measures of RV-PV function including the transthoracic echocardiogram parameter tricuspid annular plane systolic ejection (TAPSE), contrast-enhanced cardiac MRI and heart rate variability assessed by Holter monitoring. This design (excluding a placebo-placebo arm) was selected for ethical concerns and to provide optimal efficiency and active therapy to all study subjects. It also allows for comparisons between the two monotherapies and with combination therapy.
The aim of the study is to value, in patients with chronic kidney disease and hypertension, whether medical therapy plus interventional renal artery revascularization is superior to medical therapy alone for the treatment of hemodynamically significant (>70%) atherosclerotic renal artery stenosis, diagnosed by duplex doppler ultrasonography and confirmed by magnetic resonance angiography, in terms of avoidance of the progression of renal damage, control of hypertension and in reducing the cerebro and cardiovascular complications.
Renal transplantation of children started in Norway in 1970.Since the beginning, >80% of renal transplants are provided from Living Donors(mainly parents), short pre-transplant dialysis time( median 4 months) and 50% of transplantations are performed before dialysis is needed.This gives good premises for graft survival and avoidance of detrimental effects of dialysis. However, renal transplanted children are subjected to an increased cardiovascular morbidity and mortality in adulthood due to consequences of chronic renal failure and immunosuppressive treatment.Cardiovascular death comprises 30-40% of death causes. In this cross-sectional study we evaluate cardiovascular risk factors in childhood- and also in young adults renal transplanted in childhood. Focus is cardiorespiratory fitness using treadmill testing,24h BP measurements, anthropometrics including waist circumference,echocardiography,intima media thickness of carotids, glucose intolerance test.Participants are also requested to fill out physical activity recalls and Quality of life questionnaires.
Peri-operative fluid therapy is a controversial area with few randomized trials to guide practice. Fluid management has a significant influence on outcome following surgery. Yet practically, fluid prescription practice during this period is sub-optimal, resulting in avoidable iatrogenic complications. Several studies have assessed the effect of a 'liberal' vs. a 'restrictive' perioperative fluid regimen on post-operative outcome. However, most of these studies have focused primarily on intra-operative fluid management, whereas postoperative strategies have been less well defined, even though the immediate postoperative period is of critical importance to the patient's recovery. Moreover, whereas intra-operative fluid administration is monitored by the anesthesiologist, postoperatively it is less supervised and may result in excess or lack of intravenous (IV) fluids. Therefore, fluid management audit at the post-anesthesia care unit (PACU) is of paramount importance for patient healthcare. The objective of this study is to follow and report the current practice of fluid administration in the PACU of Tel Aviv Sourasky Medical Center, for an extended period of time as a first step towards establishing evidence-based guidelines for postoperative fluid management.
The purpose of TEAhM is to determine if telehealth blood pressure stations can be installed and used in senior nutrition centers and to do a preliminary comparison of blood pressure outcomes among nutrition center clients who use the telehealth blood pressure stations compared to participants who do not use the stations. Specifically, the goals of the project are to determine if these monitors can be successfully implemented in this community-based setting, the degree to which older adults with hypertension are comfortable using the technology, and whether remote nurse monitoring of blood pressure using this technology is a feasible supplement to office-based care.
The aim of this study is to to analyze if it is possible to reach the goals of HbA1c <7.0% and blood pressure <= 130/80 mm Hg in a cohort of patients with type 2 diabetes attending a primary care unit, using ony those resources available at the unit, and provided by the Brazilian National Health System. It is an open label, observational study, with a duration of 4-6 years. Patients attending a primary care outpatient facility will be sequentially included in the study provided they give consent. They will be followed on a monthly basis by a team of physicians and nurses. Glucose, A1c, Blood PRessure will be the outcomes.
The purpose of the present study was to clarify the effects of increase in physical activity on incidence and surrogate marker of cardiovascular diseases. The working hypothesis of the present study was that the physical activity to satisfy the Japanese guideline of Ministry of Health, Labour and Welfare is effective for the primary prevention of the lifestyle-related disease.
