Filter by:Lower attainment of cardiovascular health (CVH), indicated by the American Heart Association's Life's Simple 7 (LS7; physical activity, diet, cholesterol, blood pressure, body mass index, smoking, glycemia) and Life's Essential 8 (LE8; LS7+sleep) metrics, is a major contributor to Black men having the shortest life-expectancy of any non-indigenous race/sex group. Unfortunately, a paucity of literature exists on interventions aimed at improving CVH among Black men. The team of clinician scientists and community partners co-developed a community-based lifestyle intervention titled Black Impact: a 24-week intervention for Black men with less-than-ideal CVH (<4 LS7 metrics in the ideal range) with 45 minutes of weekly physical activity, 45 minutes of weekly health education, and engagement with a health coach, group fitness trainer, and community health worker. Single-arm pilot testing of the intervention (n=74) revealed high feasibility, acceptability, and retention and a 0.93 (95% confidence interval: 0.40, 1.46, p<0.001) point increase in LS7 score at 24 weeks. Secondary outcomes included improvements in psychosocial stress (i.e., perceived stress, depressive symptoms), patient activation, and social needs. Thus, robustly powered clinical trials are needed to determine the efficacy of Black Impact and to evaluate the underlying interpersonal and molecular pathways by which Black Impact improves psychosocial stress and CVH. Thus, the investigators propose a randomized, wait-list controlled trial of Black Impact. This novel, community-based intervention to provide a scalable model to improve CVH and psychosocial stress at the population level and evaluate the biological underpinnings by which the intervention mitigates cardiovascular disease risk. The proposed study aligns with American Heart Association's commitment to addressing CVH equity through innovative, multi-modal solutions.
The goal of this observational study is to learn how accurately blood pressure can be measured using a contactless radar device. The main questions the study aims to answer are: 1. how does blood pressure measured using radar compare with blood pressure using a cuff in patients with known high blood pressure? 2. how does blood pressure measured using radar compare with invasive blood pressure during a coronary angiogram? 3. can the radar blood pressure machine be used to measure blood pressuring during an MRI scan of the heart? 4. can the radar blood pressure machine be used to measure blood pressure during exercise? Participants in this study will have the following tests: Group 1: blood pressure measured with the radar device and a cuff when resting Group 2: blood pressure measured with the radar device and by placing a small tube inside the arteries of the wrist (during a clinical procedure) Group 3: blood pressure measured with the radar device and a cuff during a cardiac MRI scan Group 4: blood pressure measured with the radar device and a cuff during exercise
An MRI study to examine the relationship between blood pressure and cerebral blood flow in patients with subarachnoidal hemorrhage and suspect or verified vasospasm.
The investigators aimed to investigate the effects of continuous infusion of norepinephrine before and after general anesthesia induction on the occurrence of post-induction hypotension.
The purpose of this study is to assess the effects of an 8-week supervised high-intensity interval training (HIIT) program (vs. physical activity recommendations according to current guidelines) on a comprehensive panel of circulating sphingolipids in middle-aged females and males at elevated cardiometabolic risk.
Snus is a type of snuff that is administered sublabially, that has not been studied regarding the effects on home blood pressure and metabolism on a longer time frame. The primary aim of this study is to evaluate the effect of snus on home BP within weeks to months in former snus users who continue to not use snus or relapse in daily snus use, respectively. The secondary aim is to evaluate the effects on metabolic measurements. The hypothesis is that BP will increase amongst the participants that resume snus intake. 28 healthy volunteers with a pre-existing daily use of snus will be recruited and followed during snus cessation. Home blood pressure, lipid and metabolic markers will be measured before and after snus cessation, as well as after snus relapse if such a relapse occurs.
This randomized, 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 goal of this interventional study is to test whether sodium-glucose cotransporter 2 inhibitors (SGLT2i) reduce the effects of high dietary sodium intake in patients with type 2 diabetes. Participants will undergo a dietary intervention consisting of a week of high-sodium diet, followed by a week of low-sodium diet. At the end of each week the patients will undergo: - 24-h ambulatory blood pressure measurement; - 24-h urine collection; - bioimpedance analysis for body composition determination; - blood and urine tests. The study will compare patients treated with SGLT2i and patients not treated with SGLT2i to test whether the treatment reduces the effects of high sodium intake on blood pressure, body composition and biochemical variables.
Current forms of pharmacologic and non-pharmacologic treatments for hypotension and orthostatic hypotension (OH) remain inadequate during acute inpatient rehabilitation (AIR) following a traumatic spinal cord injury (SCI). A critical need exists for the identification of safe, practical, and effective treatment options that stabilize blood pressure (BP) after traumatic SCI. Recent published evidence suggests that transcutaneous Spinal Cord Stimulation (TSCS) can be used to raise seated BP, and mitigate the falls in BP during orthostatic repositioning in individuals with chronic SCI. This site-specific project will focus on the use of TSCS to stabilizing seated BP and mitigate the fall in BP during orthostatic repositioning during AIR following traumatic SCI.
This is a randomized trial investigating whether continuous norepinephrine administration via an infusion pump - compared to manual bolus administration - increases blood pressure stability within the first 15 minutes of anesthetic induction in non-cardiac surgery patients. The secondary endpoints area under a MAP of 65, 60, 50, and 40 mmHg [mmHg × min], cumulative duration of a MAP <65, <60, <50, and <40 mmHg [min], area above a MAP of 100, 110, 120, and 140 mmHg [mmHg min], cumulative duration of a MAP >100, >110, >120, and >140 mmHg [min] and cumulative dose of norepinephrine indexed to body weight [μg/kg] within the first 15 minutes of anesthetic induction will be assessed.
