After the participant meets all inclusion and exclusion criteria, they will be randomized equally to either the Resistance Training group (RT) or Aerobic Training group (AT). Both groups will participate in an 8 week initial control period, followed by 8 weeks of supervised exercise training, followed by 8 weeks of deconditioning. All participants will undergo the same assessments and procedures one time prior to the initial 8 week control period, and at each of the three periods. Assessments include: blood draws; arterial stiffness testing; ultrasounds of the brachial artery to measure flow-mediated dilation (FMD); gluteal adipose tissue biopsies; exercise testing to determine VO2 max; body composition analysis via DEXA scans; ambulatory blood pressure measurement; diet analysis via food journals; medical history questionnaires; urine analysis for pregnancy; and activity monitoring via accelerometer. Total participation will be 24-26 weeks. Read Less

Salt sensitive hypertension is a significant health problem worldwide and a primary modifiable risk factor for renal, cardiovascular, and cerebrovascular diseases. Yet, the underlying mechanisms remain poorly understood. The proposed study determines how renal oxygenation and substrate metabolism differs between individuals with and without salt sensitivity, with the ultimate goal of identifying mechanisms, diagnostic criteria, and treatment strategies for salt sensitive hypertension.

The investigators have designed a group randomized, multi-level, sustainable stroke and cardiovascular disease (CVD) prevention trial - "Blood Pressure: Improving Control among Alaska Native People" (BP-ICAN) - that targets blood pressure control among Alaska Native and American Indian people diagnosed with hypertension. Washington State University will assist with design, provides general scientific and clinical consulting, will help guide implementation and conduct statistical analyses. The purpose of the study is to see if monitoring blood pressure at home improves the management of hypertension. Participants will include adults who have a diagnosis of hypertension and have not achieved blood pressure control. During the pandemic, blood pressure control will be assessed during a week long study of home blood pressure readings. This study will include both a control arm (treatment as usual) and an intervention arm. Primary Care Center (PCC) provider teams and associated panels of Alaska Native or American Indian (ANAI) adults will be randomized into the control or intervention arm. The investigators will recruit up to 10 ANAI adults per PCC provider for a total of 324 participants. Intervention participants will receive a home blood pressure monitor (HBPM), upload personal home blood pressure values into a data mall, and be encouraged to communicate with providers and pharmacists about HBPM results using an online electronic health record application, telephone, or other existing clinical processes. HBPM measurements for each intervention arm participant will be provided to provider teams and integrated pharmacists. Control participants will receive care as usual. The investigators will collect data from study participants in both the intervention and control arms over a 12 month period. Participants will meet with investigators at time of consent (baseline), and 3, 6, and 12 months after baseline. At each visit, participants will have blood pressure measured using 3 methods (aneroid sphygmomanometer, automated Omron upper arm cuff device, and automated Omron wrist cuff device), complete surveys, and have height, weight, and arm circumference measured. In-person measures are omitted during the pandemic and only one method of blood pressure measurement is used (upper arm cuff device). Clinical and service utilization information will be electronically queried with participant consent. The investigators will examine whether participants in the intervention arm have better blood pressure control at the end of the 12 month period than participants in the control arm. Read Less

The purpose of our study is to understand the extent to which the blood vessels are affected by glucose and fat (lipids) in lean healthy adults and if these changes in the blood vessels contribute to the development of high blood pressure. Read Less

Hypertension is a major risk factor for cardiovascular disease, and a leading cause of death worldwide. Only about 50% of hypertension patients have good blood pressure control. Patients with low health literacy have worse blood pressure control, perhaps because they find it harder to interpret whether blood pressure readings are high or low, reflect good or bad blood pressure control, and indicate a need for behavior change or medication use. The American Heart Association has called for broad efforts to help empower hypertension patients from different backgrounds to control their blood pressure. Therefore, the investigators will evaluate different ways for helping hypertension patients to interpret their blood pressure readings and motivate blood pressure control, in a sample of hypertension patients varying in health literacy, age, and socio-economic status. Their strategy is based on insights from behavioral science studies, which suggest that people find it easier to interpret numbers when they can see the range of possible numbers. Aim 1: Based on existing communications, the investigators will create 3 blood pressure communications: (A) a basic table showing only the normal blood pressure range, which is often used in clinical practice and online communications about blood pressure, but may make it hard to interpret numbers outside of the normal range, potentially undermining behavior change intentions; (B) an enhanced table showing how combinations of diastolic and systolic blood pressure reflect normal, elevated and hypertension ranges, from the American Heart Association; (C) an enhanced graph to be adapted from Blood Pressure UK to show the same color-coded ranges as the enhanced table, with diastolic blood pressure on the x-axis and systolic blood pressure on the y-axis. Aim 2: : In a sample of 650 diagnosed hypertension patients recruited through the Pitt+Me Patient Registry at the University of Pittsburgh Medical Center (UPMC), the investigators will evaluate whether being presented with the enhanced table or graph (vs. basic table) affects patients' self-reported blood pressure measurement (as averaged across two measurements taken at the time of the survey at least 1 minute apart, as per directions of the American Heart Association), and improves interpretations of these two blood pressure readings and of hypothetical blood pressure readings, as well as behavior change intentions. Aim 3: The investigators will examine whether Aim 2 findings vary by health literacy, age, and SES. Read Less

The purpose of this study (PASSION study) is to monitor symptoms of chronic pain before and after 2 weeks of a standard drug commonly used to treat elevated blood pressure compared with 2 weeks of placebo (crossover design) so that we may better understand how blood pressure affects your level of pain. This study is not testing an experimental drug. Read Less

The purpose of this study is to assess the effectiveness of a multi-gene panel to determine which subjects are likely to respond to renal denervation therapy with Medtronic's Symplicity Spyral™ multi-electrode renal denervation system. Read Less

High blood pressure is the greatest threat to the global burden of disease, contributing to an estimated 9.4 million deaths a year. Cardiovascular disease morbidity and mortality are positively correlated with the degree of elevation of blood pressure, without any evidence of a threshold down to at least 115/75 mm Hg[2]. Hypertension is common, and nearly every clinician in every specialty deals either directly or indirectly with managing it or its consequences. The population age 65 years or older numbered 46.2 million in 2014 and they represent 14.5% of the US population, the older population in 2030 is projected to be more than twice as large as in 2000, growing from 35 million to 74 million and representing 21 percent of the total U.S. population and it is expected to more than double to 98 million in 2060.Proper managing and controlling blood pressure markedly improves patient morbidity and mortality, SHEP study showed that in persons aged 60 years and over with isolated systolic hypertension, antihypertensive stepped-care drug treatment with low-dose chlorthalidone as step 1 medication reduced the incidence of total stroke by 36%.This study will estimate the prevalence of hypertension diagnosis, treatment and outcomes in a Family Practice population. It is a hypothesis generating study Read Less

The purpose of the ESCAPE Study is to determine the extent to which epidural spinal cord stimulation (SCS) reduces arterial blood pressure (BP) in patients which chronic low back pain and hypertension. We also aim to determine the extent to which higher baseline BP (i.e., hypertension) predicts reductions in pain following SCS implant. This is an observational study of patients undergoing an implantation of a SCS device. Read Less
