Filter by:The Potassium Intake-response Trial to Control Hypertension (PITCH) will test the intake-response relationship between potassium supplementation and blood pressure, which may inform clinical guidelines on the optimal level of potassium supplementation for blood pressure lowering among adults with elevated blood pressure or hypertension and dietary guidelines for population intake.
This randomized, double blinded, sham-control trial aims to evaluate the efficacy and safety of a novel focused power ultrasound mediated inferior perirenal adipose tissue modification therapy for essential hypertension.
The investigators propose to leverage new technology using the Qardio app for iPhone and Android devices to automatically upload blood pressures, using a well-validated blue tooth blood pressure monitor (QardioArm), directly into the Duke electronic health record system (EPIC). Further, the investigators propose to develop an automated EHR (electronic health record) messaging system utilizing the home blood pressures that will be sent to the participant's PCP, with copies to the participant and the primary oncologist. This is a 12-week prospective non-randomized implementation study. 40 patients who are 18-74 years old who fall under the following criteria will be screened: 10 women with Stage 1-III breast cancer who are receiving either an anthracycleine of antiHER2 therapy, 10 men with prostate cancer on ADT, 10 individuals with CLL on ibrutinib therapy, and 10 individuals who are hematopoietic stem cell transplantation (HSCT) survivors. In Phase 1 (Weeks 1-4) of the study, participants will self-monitor their blood pressure using the QardioArm wireless upper arm blood pressure monitor 3 times per week. In Phase 2 (Weeks 5-12), the investigators will implement the auto-messaging system triggered by an abnormal weekly average systolic or diastolic blood pressure. The investigators will adapt the conceptual framework of Muldoon and colleagues whereby home blood pressure monitoring is combined with office blood pressures to optimize data for the primary care provider's clinical decision making. {Participants will be asked to complete a paper survey, upon enrollment, that will include life chaos and medication adherence questions. There will also be an end-of-study feedback survey (usability and acceptability questions through REDCap) for both the participants and their primary care providers. This is an implementation study with a descriptive analysis. The data generated from the study will be used in future studies, including testing of different interventions aimed at optimizing blood pressure control among patients on active cancer therapy. This study presents no greater than minimal risk to the subjects and adverse events are not anticipated.
Investigators will identify a group of patients with complete heart block and a dual chamber pacemaker who will be expected to be able to exercise on a treadmill. Investigators will utilize symptom logs, cuff and continuous blood pressure monitoring. It is planned to study the symptomatic impact of loss of AV synchrony at significant levels of exercise.
This study will investigate the relationship between resistance training load and repetitions on cardiometabolic outcomes. The primary objective of this clinical trial is to determine whether high load or low load resistance exercise training affects arterial stiffness in overweight or obese men and women. Our secondary objectives are to investigate the effects of high and low load RT on vascular function, cardiac structure, and markers of insulin sensitivity. Finally, we are going to preliminarily explore the effects of resistance training on intestinal bacteria.
The study will compare agreement of invasive blood pressure measurements with non-invasive blood pressure measurements measured with a conical blood pressure and large standard upper arm rectangular cuff in morbidly obese severely hypertensive (systolic blood pressure > 160 mmHg) parturients.
1. Aim- This study is aimed to access the accuracy of TensorTip MTX device measuring Hemoglobin A1C, Oxygen Concentration and Saturation ,Carbon Dioxide, Blood pH, Hemoglobin, Hematocrit, Red Cells Count, platelets, Blood Urea Nitrogen, Sodium, Potassium, Chloride, total bilirubin, cholesterol (HDL, LDL), Serum Creatinine, Peripheral Pulse Rate, Blood Pressure, Mean Arterial Pressure, cardiac output, cardiac index, stoke volume and blood gases compared with the simultaneous results from hospital references device (when available) 2. Hypothesis- Human physiological biomarkers may be measured from the color distribution of the internal or external (skin) tissue. The technology of the TensorTip device is based on the color distribution of the peripheral blood tissue, which enables the measurement of certain biomarkers and vital signs under consideration
This study is required to demonstrate that the non-invasive blood pressure (NIBP) measurement algorithms on two commercially available multifunction hemodynamic acquisition modules, the Patient Data Module (PDM) equipped with the DINAMAP® SUPERSTAT algorithm ("PDM-SUPERSTAT") and the Patient Side Module (PSM) equipped with Datex-Ohmeda GE algorithm ("PSM-Datex-Ohmeda"), provide accurate NIBP measurements in accordance with the guidelines provided by the most recent International Organization for Standardization (ISO) 81060-2:2013. Notably, the new ISO 81060-2:2013 supersedes the previous 2009 version of this standard, and this study is being conducted in accordance with the most recent applicable standards. This study will assess neonate, infant, children, pediatric, adolescent, and adult patients as well as adults with chronic atrial fibrillation in a population that requires non-emergent heart catheterization. This is a study conducted to satisfy both standards for two NIBP devices and, as such, does not require a statistical hypothesis.
The kidneys are an important regulator of blood pressure. Previous research has shown that disrupting the nerves (denervate) of the kidney may successfully decrease blood pressure. In the past, one technique that was used to treat severe high blood pressure was a surgical procedure to cut these nerves. However, this surgery is no longer commonly performed. Another approach to disrupting these nerves is to use the Beta-Cath 3.5F system to deliver a small amount of radiation to the treatment zone. The Beta-Cath 3.5F System (Novoste) is currently approved in the United States to deliver ion dose therapy to re-narrowings that form in the coronary arteries in the heart. This trial is assessing the safety of treating patients with the Beta-Cath 3.5F System (Novoste) to denervate the nerves around the kidney to help control blood pressure in patients with uncontrolled hypertension. 1. Renal artery brachytherapy with beta-emitting source is safe. 2. Renal artery brachytherapy with beta-emitting source can reduce systolic/diastolic blood pressure via renal denervation mechanism within 6 months post treatment.
The purpose of this study is to determine if reduction in premature ventricular contraction (PVC) burden results in a decrease in blood pressure, sympathetic outflow, plasma catecholamines and an improvement in baroreflex gain. Flecainide will be used for PVC suppression in a randomized, double-blinded, crossover fashion.
