Active clinical trials for "Hypertension"

Older adults with subjective cognitive decline (SCD) may represent a portion of the population experiencing early sings of cognitive decline. Systolic hypertension is a major contributor to cognitive impairment. High-intensity aerobic interval training (HIT) yields greater fitness and vascular health improvements compared to moderate-intensity aerobic continuous training (MCT). No randomized controlled trials, however, have investigated the effects HIT or MCT on cognition in older adults with hypertension and SCD. Much less is known regarding whether combining HIT or MCT with mind-motor training would culminate additive benefits to cognition. Therefore, the overarching goal of our research is to deliver a group-based exercise program combining mind-motor training with HIT or MCT to older adults with hypertension and SCD. Participants will be randomized into two groups. Participants in both groups will receive 15 minutes of square stepping exercise (SSE) followed by either 45 minutes of HIT (N=70) or 45 minutes of MCT (N=70). In total, both groups will exercise 60 min/day, 3 days/week for 6 months. The effects of both interventions will be evaluated on systolic and diastolic office/ambulatory blood pressure and global and domain-specific cognitive functioning.

Evaluate for accuracy and reproducibility of data collected via the participant-operated Walk.Talk.Track. (WTT) app combined with Apple Watch during in-clinic, technician proctored 6MWT's. Determine whether the WTT app on the Apple Watch can accurately collect information on distance traveled and heart rate (HR) during in-clinic 6MWT run by American Thoracic Society (ATS) guidelines Determine whether participants can operate the WTT app and Apple Watch effectively to gather accurate data in a monitored and home-based setting Prospectively monitor for changes in WTT app recorded 6MWT results following initiation of therapy in a treatment naïve cohort of PAH participants Evaluate whether changes from baseline in 6 minute walk distance (6MWD) and heart rate recovery at one minute (HRR1) as well as other variables that have been associated with disease severity in PAH and left-sided heart disease (resting HR, heart rate variability [HRV], chronotropic index [CI]) can be identified before the 12-week follow up when comparing the treatment arm and the control arm Evaluate whether changes from baseline in the HRR1, resting HR, HRV and/or CI are more evident in treatment responders when compared to treatment non-responders.

The main OBJECTIVE of this proposal is to extend the investigator's preclinical findings on the role of epigenetics and DNA damage and Bromodomain-Containing Protein 4 (BRD4) inhibition as a therapy for a devastating disease, pulmonary arterial hypertension (PAH). There is strong evidence that BRD4 plays a key role in the pathological phenotype in PAH accounting for disease progression and that BRD4 inhibition can reverse PAH in several animal models. Intriguingly, coronary artery disease (CAD) and metabolic syndrome are more prevalent in PAH compared with the global population, suggesting a link between these diseases. Interestingly, BRD4 is also a trigger for calcification and remodeling processes and regulates transcription of lipoprotein and inflammatory factors, all of which are important in PAH and CAD. Apabetalone, an orally available BRD4 inhibitor, is now in a clinical development stage with a good safety profile. At this stage, the investigators propose a pilot study to assess the feasibility of a Phase 2 clinical trial assessing apabetalone in the PAH population. The overall HYPOTHESIS is that BRD4 inhibition with apabetalone is a safe and effective therapy for PAH.

The sodium-glucose cotransporter 2 (SGLT2) inhibitors are an exciting new class of antidiabetic drugs that cause a modest reduction in high blood pressure and large reductions in the risk of cardiovascular disease (CVD) outcomes and renal outcomes in patients with advanced type 2 diabetes and very high CVD risk. However, the mechanistic underpinning of these CVD benefits is not well understood. Mechanistic studies are needed to define specific biologic targets and thus optimize therapeutic benefits. Type 2 diabetes mellitus is firmly established as a state of sympathetic neural overactivity, which may contribute to coexistent hypertension, heart failure, sudden cardiac death, macro- and micro-vascular complications of diabetes, and diabetic nephropathy. In patients recently diagnosed with Type 2 diabetes, microelectrode recordings of sympathetic nerve activity (SNA) targeted to the skeletal muscle circulation have shown both: abnormally high resting (ambient) levels of sympathetic nerve activity; and greatly exaggerated increases in sympathetic nerve activity during isometric (static) handgrip exercise. The purpose of the proposed study is to determine if Ertugliflozin, a SGLT2 inhibitor, constitutes an effective countermeasure against sympathetic overactivity in patients with diagnosed hypertension and recently diagnosed type 2 diabetes by normalizing the high resting level of muscle sympathetic nerve activity (SNA) as measured by intraneural microelectrodes in the peroneal nerve. Thus, an effective countermeasure is an urgent unmet medical need. The SGLT2 inhibitors hold exciting promise to address this need.

To test the hypothesis that sympatholytic antihypertensive antihypertensive therapy (αβ-blocker - carvedilol) will reduce out-of-clinic ambulatory BP to a greater extent by blocking sympathetic activity than non-sympatholytic antihypertensive medication (dihydropyridine calcium channel blocker - amlodipine) in individuals with masked hypertension.

During endotracheal intubation, it is known that la laryngoscopy has significant effects, such as tachycardia and blood pressure increase, which may be harmful, especially in those with cardiovascular disease. Different studies comparing laryngeal stimulation and there resulting hemodynamic response made with various intubation devices are available in the literature. The investigators planned to work with the hypothesis that endotracheal intubation with videolaryngoscopy would have less hemodynamic response traditional (Macintosh) laryngoscopy and the use of videolaryngoscopy would result in wider vision with less laryngeal stimulation.

The SOMNOtouch NIBP is a cuffless device for continuous blood pressure measurement. The device is widely used, but validation for 24-hour ambulatory blood pressure measurement (ABPM) is limited. This study seeks to validate the SOMNOtouch device for use in 24-hour ABMP as compared to a validated oscillometric device for 24-hour ABPM. A total of 60 patients with indication for 24-hour BP measurement will be recruited from our tertiary hypertension Clinic. All included patients will conduct dual 24-hour ABPM with both the SOMNOtouch NIBP and a the oscillometric device. Furthermore, patients will undergo measurement of arterial stiffness with a Sphygmocor device as well as complete a questionaire on device related discomfort.

ARTERY is a randomized clinical trial that investigates the benefit of a predictive modeling artificial intelligence in improving the management of anti-hypertensive medication treatment.

Patients were classified into two equal groups using the presence or absence of hypertension during pregnancy into: hypertensive group (BP>140/90) and normotensive group (BP≤140/90. The surgical time intervals are assessed and classified the patients accordingly into short and log time interval subgroups (induction of regional anesthesia to delivery (I-D), initial skin incision to delivery (S-D), and uterine incision to delivery (U-D)
