Filter by:The overall goal of this large, pragmatic, comparative effectiveness trial is to test the hypothesis that among at-risk individuals, 162 mg/day aspirin is superior to 81 mg/day in preventing Hypertensive disorders of pregnancy (HDP), and that there are multiple factors associated with adherence with aspirin therapy that will be important to identify to enable optimal implementation of study findings and population-level benefits.
The diagnosis of hypertensive disease during pregnancy is predicated on strict blood pressure thresholds: 140/90 on at least two occasions measured four hours apart for both gestational hypertension and preeclampsia. An improvement in diagnostic accuracy of even 5mm Hg would be significant, as reflected by the US Association for the Advancement of Medical Instrumentation (AAMI), the British Hypertension Society, the European Society of Hypertension (ESH) Working Group on Blood Pressure (BP) Monitoring, and the International Organization for Standardization (ISO)consensus for validation of non-invasive blood pressure (NIBP) devices during pregnancy. Given the known inaccuracies of upper arm cylindrical cuff measurements in morbidly obese patients, a conical cuff which provides more accurate measurements will translate into direct patient benefit via more informed diagnosis and management. Fewer women may be exposed to unnecessary treatment, preterm delivery, and/or cesarean section. Recognizing the increasing prevalence of morbid obesity and hypertensive disease amongst pregnant women in the United States, the identification of a more accurate non-invasive cuff is desperately needed. Increasing the accuracy of NIBP measurements on Labor and Delivery has the potential to directly impact the management of tens of thousands of morbidly obese pregnant women diagnosed with hypertensive disease in the United States every year. Establishing the level of agreement between conical forearm and cylindrical upper arm cuffs will shed light on the presence and magnitude of any disparity between measurement methods. STUDY ENDPOINTS: Primary Outcome Measures: - Agreement between conical and cylindrical cuff systolic blood pressure across groups - Agreement between conical and cylindrical cuff diastolic blood pressure across groups Secondary Outcome Measures: ā¢ Agreement between conical and cylindrical cuff mean arterial pressure
The investigators are piloting a 3 month community-based lifestyle medicine program that incorporates experiences and education in urban agriculture, nutrition, culinary arts, and physical fitness to test the hypothesis whether this improves clinical and socio-behavioral outcomes of participants with Cardiovascular Kidney Metabolic (CKM) syndrome (high blood pressure, diabetes, high cholesterol, heart disease, and obesity) in comparison to the current medical care model (usual care) or providing healthy produce (medically tailored groceries).
This study is a human-centered, three-arm, parallel-group, randomized control, implementation trial (n=75) to compare MTM (Medically Tailored Meals) only (14 meals delivered weekly for 10 weeks) vs. MTM + SMA (Shared Medical Appointments; once weekly sessions for 10 weeks) vs. a wait-list control group (MTM-Later) in patients with hypertension, type 2 diabetes, obesity, and/or metabolic syndrome. All intervention components will be culturally congruent (e.g., MTMs will include food that converges with culturally relevant diets and SMAs will be delivered by individuals with racial concordance to the target community). Primary outcomes will be implementation (recruitment and retention rates) and feasibility (engagement and satisfaction). Participants will be recruited from Cleveland Clinic's South Pointe Hospital in Warrensville Heights, a predominantly Black community with low socioeconomic status and high cardiovascular disease morbidity.
This study aims to investigate the effect of different types of glaucoma surgery on aqueous dynamics parameters (IOP, aqueous flow rate, trabecular outflow facility and uveoscleral outflow) in patients with uncontrolled open angle glaucoma or ocular hypertension (OHT)
Aims and objective: The primary objective of this study was to assess the effects of a traditional Chinese Qigong practice known as Wuqinxi on activity toleranceļ¼negative emotions and quality of life in pulmonary arterial hypertension patients. Methods: In the current prospective, randomized-controlled clinical trial, 60 patients with pulmonary arterial hypertension were randomly assigned to one of two groups: intervention or control. Participants in the intervention group received targeted pharmacological therapy and five sessions of qigong exercise per week. In contrast, individuals in the control group underwent targeted drug therapy and routine care. Observe the change in exercise tolerance as measured by the 6-minute walking distance (6MWD). Serological indicators (n-terminal brain natriuretic peptide precursor, NT-pro BNP) ,negative emotions(PHQ-9/GAD-7)and the MOS Item Short Form Health Survey (SF-36) or emPHasis-10 were used to assess patients condition and quality of life.
Resistant arterial hypertension (RAH) is a complex and multifactorial syndrome, with hyperactivity of the sympathetic nervous system (SNS) and reduction of vagal activity being considered some of the main causes of refractoriness to treatment. Seen from the outside, it resembles a complicated (see lat. "Cum plicate") or complex disease (see lat. "Cum plexus"), Chaotic with the participation of several open systems. For example, in recent years some relationships have been demonstrated between the autonomic nervous systems, synaptic mediators, hormones, inflammatory and immune responses. However, these findings have not been investigated together and systematically. In the present project, we intend to establish and compare, in an integrated way, the clinical alterations present in RAH (resistant and refractory), hemodynamic variables, autonomous activity (sympathetic and baroreflex) and interactions with the neuroimmune-endocrine systems. To this end, we will test the hypothesis that resistant patients have greater damage to the autonomic nervous system (ANS) associated with exacerbated systemic and hormonal inflammatory profile, including SNA mediators (noradrenaline and acetylcholinesterase). This is also intended to determine the behavior (deterministic or chaotic) of the systems evaluated (mentioned above) in volunteers with RAH. Sample and methods: The sample space (calculated) will consist of 72 individuals, being: - 18 refractory hypertensive (HRT); II- 18 resistant hypertensive patients (HRfT); III- 18 controlled hypertensive (1-2 drugs) (CAH); and IV- 18 healthy normotensive individuals. This is a prospective, double-blind study (patient and professional-technician), paired (1 X 4), in which the 72 volunteers will be evaluated by the methods set out below. We will also have the chance to observe whether resistant and refractory hypertension share the same pathophysiological bases and clinical manifestations ("deterministic-isolated or cardiovascular chaos") by analyzing the patterns of cardiovascular variability (MAPA and Holter) (SpaceLabs, USA; DynaMap, Brazil), inflammatory and hormonal mediators (ELISA) in the resistant hypertension - RHT and refratary hypertension - HfRT groups. Central pressure (CP) and arterial stiffness (pulse wave velocity, VOP) (Sphymocor, ATCor, USA) will also be assessed. Healthy normotensive (NT) and controlled hypertension (CAH) will be evaluated in an identical way to control the other groups. Perspectives: The findings will improve the clinical knowledge based on pathophysiology about Resistant Hypertension and, mainly, the bases of pharmacological treatment and with implantable devices (stimulation of baroreceptors and sympathetic denervation) used in this condition.
The goal of this clinical trial is to learn if positive airway pressure (CPAP) therapy works for blood pressure (BP) control in obstructive sleep apnea (OSA) adult patients plus undiagnosed hypertension (HBP), using a cuffless bracelet for continual optical BP monitoring (AKTIIA OBPM). It will also learn if CPAP improves cardiac function in these patients using speckle tracking echocardiography (STE) and to learn about ease of use and patient experience with AKTIIA device and AKTIIA OBPM. The main questions it aims to answer are: - Does CPAP reduce systolic BP (and other BP metrics) in this population? - Does CPAP improve cardiac function in the same population? Researchers will compare BP metrics derived from AKTIIA OBPM and STE metrics in a before and after CPAP therapy to evaluate its therapeutic effect. Participants will: - Take a CPAP titration and telemonitoring program for 12 weeks (from the titration date) - Take an AKTIIA OBPM one week before CPAP and 12 weeks since CPAP titration date - Take a STE test twice, before starting CPAP and 12 weeks after CPAP titration date - Take an online survey about easy of use and patient experience with AKTIIA OBPM device
The goal of this clinical trial is to better understand how different strategies, timing, and enhancements to medically tailored food delivery will address structural inequities in the food environment, empower communities to sustain behavior change, and ultimately improve postpartum weight control to prevent chronic hypertension-a potent contributor to disparate mortality among Black women. - To conduct a pilot randomized control trial to test the feasibility, acceptability, and effectiveness of a multi-component Medically Tailored Food (MTF) intervention, MFeast ENHANCED (a hybrid MTF intervention with a patient-activated change from prepared meals to fresh food delivery, customized for postpartum people, culturally customized for engagement and adherence, and food provision for dependents) versus MFeast Usual Care (prepared medically tailored foods only). - To test sustainability and scalability. Participants will: - Respond to online surveys (supported by study team members via scheduled phone calls) via REDCap links shared before each study visit at baseline, 3 and 6 months post-delivery after the baseline survey. - Submit anthropometric data (e.g. weight and blood pressure)
The goal of this study is to compare two types of exercises, isometric exercise (like squats and planks) and aerobic exercise (such as running), to see which one is more effective at improving blood pressure in teenagers aged 13 to 17.5 years. The main question the study aims to answer is: - Do the effects of one session of isometric exercise on the blood pressure of adolescents compare to the effects of one session of aerobic exercise? Adolescents diagnosed with high blood pressure may qualify for this study. Participants will be randomly assigned to either a single session of isometric exercise or a single session of aerobic exercise. - Participants will attend 3 study visits in total. - Study visits should be completed within 4 weeks of enrollment. - At the initial visit, samples (example: blood) will be collected and body measurements will be taken. - Participants will be asked to answer questionnaires (diet, growth, and others) - At visit 2, participants will have their blood pressure measured using a 24 hour blood pressure monitor. - At visit 3, participants will participate in a single session of either aerobic or isometric exercise. They will wear a 24-hour blood pressure monitor immediately after the exercise session.
