Filter by:Background: Although exercise training is a well described therapy for some cardiometabolic diseases such as obesity, type 2 diabetes, arterial hypertension, and metabolic syndrome, there is scarcity of knowledge about the post-exercise period term as 'detraining' where usually all physiological adaptations as cardiovascular and metabolic benefits are lost due to physical inactivity. Likewise, as some exercise training modalities as high-intensity interval training improve vascular parameters including endothelial dysfunction parameters as flow-mediated dilation (FMD%), and carotid-intima media thickness (c-IMT) during the 'training' period, there is little knowledge about how many 'volume' or 'intensity' of exercise training or physical activity per week is needed to maintain the exercise training benefits in populations with cardiometabolic risk factors such as those patients with arterial hypertension. This information will be of great interest for both improving and maintaining the vascular profile and health of Chilean adults with risk factors and to maintain a better vascular profile. Objective: To study the beneficial adaptations from the 'training' and 'detraining' period of exercise training on functional and structural vascular parameters in healthy and cardiometabolic risk factors adult subjects to improve the health profile. Methods: The investigators will conduct an experimental design of 5 groups of exercise training in healthy (controls) and hypertensive (HTN) patients (≥140 mmHg), with overweight/or obesity, men and women, with BMI ≥25 and ≤35 kg/m2, aged ≥18y, physically inactive (<150 min/week of low/moderate PA/week, or <75 min/week of vigorous PA) in the last 6 months will be invited for participating. The groups will be as follows; Group (HTNex will be compared with Group HTNcg). Group (ELEex will be compared with Group ELEcg). Group (NTex will be compared with Group NTcg). Each group will be compared in their physiological vascular adaptations before and after exercise training such as HIIT, and after 3 months of a detraining period. Results (hypothesis): The investigators hypothesized that the maintenance of vascular outcomes after the 'detraining' period is intensity-dependent in adults with HTN that participated of an exercise intervention.
The primary objective of this study is to is to assess the ability of retina specialists to successfully administer, via an intravitreal (IVT) injection, a 2 mg dose of ABP 938, using the ABP 938 aflibercept prefilled syringe (PFS), compared to a 2 mg dose of aflibercept using the aflibercept PFS.
The main objective of this prospective multisite trial is to study the evolution of TMA (thrombotic microangiopathy) induced by gemcitabin and treated by eculizumab.
The purpose of this research is to compare sympathetic function (flight or fight system) and arterial health including structure and mechanics of participants with history of spontaneous coronary artery dissection (SCAD) to age and sex matched control participants.
The purpose of this study is to understand more about why young people who were born to a hypertensive pregnancy may have increased risk of high blood pressure and are often at increased risk of heart and blood vessel disease later in life.
This study is a 60-week, two-arm, randomized, open-label, active-controlled, multi-center study in patients with Polypoidal choroidal vasculopathy (PCV) who have not previously received anti-Vascular endothelial growth factor (VEGF) treatment.
The purpose of the present study was to evaluate the outcomes of type 1 macular neovascularization (MNV), including polypoidal choroidal vasculopathy in patients treated tolerating subretinal fluid (SRF) using Aflibercept in a clinical setting. Approximately 150 patients are anticipated to be enrolled in this study. SRF is a primary type of fluid compartment prevalent in type 1 aneurysmal MNV. In a recent study, the prevalence of SRF during 24-month follow-up period was 36.7% to 38.8% in type 1 MNV and polypoidal choroidal vasculopathy (PCV), 20.0% in type 2 MNV, and 7.7% in type 3 MNV. In addition, patients with SRF showed better visual prognosis in type 1 MNV/PCV. For this reason, type 1 MNV is an appropriate candidate for evaluating the influence of tolerating SRF.
The RESTORE (ATK) above the knee study is a prospective, non- randomized, multi-center study for treatment of stenotic lesions with the Bolt Intravascular Lithotripsy System.
The purpose of the study was to evaluate the safety and efficacy of a branched type intraoperative stent system for the treatment of Stanford type A aortic dissection
This is a single site, single-blinded parallel randomized control trial that investigates a multi-level intervention to improve postpartum blood pressure in women with hypertensive disorder pregnancy. The investigators will recruit women diagnosed with a hypertensive disorder of pregnancy, identified between 3rd trimester and 2 weeks post-delivery. The investigators will randomize participants to receive usual care home blood pressure monitoring for 6 weeks versus an intervention of usual care + blood pressure and weight monitoring + a doula trained in heart health. This trial will be conducted in partnership with a local community-based organization, Healthy Start Inc.
