RiSE to Prevent Cardiovascular Disease in African Americans

Start date: August 3, 2017
Phase: N/A
Study type: Interventional

The purpose of this pilot study is to evaluate an innovative 8-wk stress reduction program called Resilience, Stress and Ethnicity (RiSE) program designed to reduce chronic stress associated with perceived discrimination among African Americans. African Americans residing in the Maywood community between the ages of 25 and 75 with at least one cardiovascular disease risk factor such as being overweight, having high blood pressure, or diabetes will be enrolled. The following specific aims will be addressed: Aim 1: Determine the feasibility and acceptability of the program as a strategy to reduce chronic stress in African Americans within the Maywood and surrounding community. Aim 2: Examine the extent to which training in RiSE (1) improves psychological well being, (2) decreases inflammatory burden, and (3) reduces cardiovascular risk in African Americans Participants will be randomized to either the RiSE program or the control (no intervention group). Participants will provide blood and saliva samples as well as complete written questionnaires asking them questions about their health, well-being, and early life at the start of the study, half way through the study (at 4 weeks), at the completion of the intervention (8 weeks) and 3 months after the completion of the intervention).

NCT ID: NCT03872856 Recruiting - Hypertension Clinical Trials

Blood Pressure-Improving Control Among Alaska Native People" (BP-ICAN)

Start date: February 19, 2019
Phase: N/A
Study type: Interventional

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, and 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. 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 500 participants. Intervention participants will receive a home blood pressure monitor (HBPM), upload their 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 their blood pressure measured using 3 methods (aneroid sphygmomanometer, automated Omron upper arm cuff device, and automated Omron wrist cuff device), complete surveys, and have their height, weight, and arm circumference measured. 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.

NCT ID: NCT03857490 Recruiting - Clinical trials for Essential Hypertension

Heat Therapy in Older Hypertensive Women

Start date: February 2019
Phase: N/A
Study type: Interventional

The prevalence of hypertension is greater in older (≥65 years) women than in older men, while the blood pressure (BP) control rate is lower in older women in the United States. Uncontrolled hypertension is a major risk factor for cardiovascular morbidity and mortality. Despite standard therapy and adherence to optimal drug regimens, over 50% of older hypertensive women still have inadequate BP control (e.g. >140/90 mmHg), and the control rate is further reduced with more aggressive BP targets recommended recently by the new 2017 ACC/AHA Hypertension Guidelines. Thus, the effectiveness of drug treatment alone in the control of hypertension among older women is limited; hence, non-pharmacological approaches are also needed to help reduce BP and cardiovascular morbidity and mortality in older hypertensive women. One adjuvant, non-pharmacological approach that offers promise in lowering BP is "heat therapy". Indeed, repeated (chronic) whole-body heat exposure has been found to decrease BP in healthy humans. Whether this is also true after regional limb heating in hypertensive patients is unknown. The global objectives of this research project are to investigate the BP lowering effect of home-based lower leg heat therapy in older women with hypertension, and to examine the impact of this therapeutic modality on neural-vascular health in these patients. Specific Aim 1 will test the hypothesis that chronic lower leg heat therapy combined with an antihypertensive drug is superior to drug treatment alone in lowering BP in older hypertensive women. We will randomly assign older hypertensive women to either an intervention group or a control group. Patients in the intervention group will perform 8 weeks of home-based lower leg heat therapy via water immersion up to the knee in a circulated bath (water temperature 42°C, 4 times per week, 45 min per session), whereas patients in the control group will immerse their legs in a thermoneutral water bath (33°C) at the same frequency and duration. All patients will also receive a fixed dose of chlorthalidone (a diuretic, 25 mg orally once daily). We will compare ambulatory BP, the BP control rate, and patient adherence and acceptability to treatment between the groups. Specific Aim 2 will test the hypothesis that chronic lower leg heat therapy will improve nitric oxide bioavailability which can decrease sympathetic vasoconstriction and improve vascular function in older hypertensive women. We will use state-of-the-art techniques of microneurography, Doppler ultrasound, applanation tonometry, and cutaneous microdialysis to assess sympathetic neural control, indices of conduit and resistance vessel vasodilator function, and interstitial metabolites (i.e. nitrate and nitrite) indicative of basal nitric oxide bioavailability in all patients enrolled in Aim 1 before and after 8 weeks of heat therapy. Information obtained from this research project will guide evidence-based clinical practice. It is anticipated that our study may lead to revision of hypertension guidelines to incorporate home-based heat therapy as adjuvant to antihypertensive drug(s) for older women, as well as other patient populations.
