A Clinical Trial on No-touch Vein Graft (NT-graft) in Coronary Surgery

Coronary artery bypass grafting (CABG) is the most common surgical procedure aimed against ischemic heart disease (IHD) in Sweden. Early and late success of CABG is the result of sustained patency of the bypass grafts. The choice of conduit (graft) for CABG has been shown to impact graft patency. The ...

Psychosocial Environmental and Chronic Disease Trends in Puerto Rico

The overall goal is to identify trends and longitudinal associations in psychosocial, food-related, and cardiometabolic risk factors that can guide public health priorities and future research needs aimed at reducing cardiovascular-related disparities in Puerto Rico. To this end, investigators will establish 'PROSPECT: Puerto Rico Observational Study of Psychosocial, Environmental, and ...

Phase N/A

Role of Sympathetic Activity and Splanchnic Capacitance in Hypertension

The splanchnic circulation contains a highly compliant venous bed which normally stores ~25% of the blood volume, and receives up to 25% of the resting cardiac output. It is highly innervated by the sympathetic nervous system, and this neural regulation results in large volume shifts that modulate blood pressure (BP). ...

A Study Evaluating the Efficacy and Safety of Ralinepag to Improve Treatment Outcomes in PAH Patients

Study ROR-PH-301 is a multicenter, randomized, double-blind, placebo-controlled study. Subjects who meet entry criteria will be randomly allocated 1:1 to receive ralinepag or placebo, in addition to their standard of care or PAH-specific background therapy, as applicable. The primary endpoint is the time (in days) from randomization to the first ...

Intima Versus Adventitia Drug Delivery to Elucidate Mechanisms of Restenosis: Magnetic Resonance Imaging

Peripheral artery disease (PAD) affects at least 12 million Americans annually with more than half a million patients undergoing an endovascular or surgical revascularization procedure in order to treat the disease. Unfortunately, about two-thirds of patients still have blockages in the leg arteries, even after these procedures. Advances in Magnetic ...

Randomized Clinical Trial PULVAB (Prophylactic Pulmonary Veins Ablation)

Prospective, multicenter, randomized trial, intended to compare three prophylactic strategies of atrial fibrillation in patients with coronary artery disease and without history of atrial fibrillation. The study includes 4 groups of patients: Group I (conventional CABG) Group II (CABG + pulmonary veins isolation). Concomitant CABG and epicardial bipolar radiofrequency pulmonary ...

Phase N/A

Evaluation of OZURDEX in Patients With Macular Edema Secondary to Retinal Vein Occlusion in China

This study will take place in China to evaluate the safety and efficacy of OZURDEX implant 700 g in the treatment of macular edema due to retinal vein occlusion (RVO) in patients who have never received treatment for RVO.

Phase

EMPOWER-1: A Multi-site Clinical Cohort Research Study to Reduce Health Inequality

This multi-centre real-world study will recruit patients across different National Health Service (NHS) sites based in England, where the overall patient population demographic profile is sufficiently variable to allow for meaningful representation of different ethnicities in the analysis of pooled data-sets. The study addresses the issue of health inequality and ...

Phase N/A

Mechanism(s) Underlying Hypotensive Response to ARB/NEP Inhibition - Aim 1

After informed consent is obtained, subjects will undergo a screening history and physical exam, and anti-hypertensive medications will be withdrawn. During this period, blood pressure (BP) will be measured every one to three days. After subjects have been off anti-hypertensive medications for three weeks (four for spironolactone), they will be ...

Phase

Randomized Clinical Trial by Conglomerates on the Efficacy of Maintenance of Physical Exercise in Myocardial Ischemia

Main objective: To assess the efficacy of a phase III cardiac rehabilitation program (CRP), based on counseling in the maintenance of physical exercise (time of physical exercise per week) for patients with myocardial ischemia (MI), once the supervised physical exercise program of phase II of CRP is completed. Secondary objectives: ...
