NCT01639937
Background: \- People with congenital heart disease may develop heart failure earlier that those who do not have the disease. One theory to explain this is that the heart s own blood supply may be different in people with congenital heart disease. Problems with this blood supply can severely damage the heart. This damage can be studied with a heart imaging test called a cardiac magnetic resonance imaging (MRI) scan. Researchers want to use this type of scan to look at the blood supply to the heart in people with congenital heart disease. Objectives: \- To learn more about the blood supply to the heart in people with congenital heart disease. Eligibility: \- Individuals at least 18 years of age who have heart defects caused by congenital heart disease. Design: * Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. * Participants will have a cardiac MRI scan to look at the blood flow to the heart. * Participants will also have a heart stress test to measure heart function during exercise. * Other imaging studies of the heart may be performed to collect more information on heart function.
NCT00121472
The purpose of this study is to determine the safety and effectiveness of the Thoratec HeartMate II Left Ventricular Assist System (LVAS) as a bridge to cardiac transplantation in end-stage heart failure patients who are listed for cardiac transplant but are at imminent risk of dying. The HeartMate II LVAS was approved by the US FDA on April 21, 2008, as a bridge to cardiac transplantation (reference PMA P060040). It was approved for commercial distribution in Canada on May 20, 2009 (reference Medical Device Licence #79765). Patients enrolled into the clinical trial will continue to be followed until all have reached a clinical outcome.
NCT02836652
This study is a prospective, multi-center, randomized, double-blind placebo-controlled study of subjects receiving the HM II LVAD as per the current FDA approved indications for use.
NCT03570697
To evaluate the effect of evolocumab on fibrous cap thickness (FCT) in participants with non-ST-elevation acute coronary syndrome (NSTE-ACS) who are taking maximally tolerated statin therapy.
NCT05185232
Congenital heart defects (CHDs) are a heterogeneous group of rare diseases of varying severity, each diagnosis with its unique set of co-morbidities. In addition to the heterogeneity, perhaps the greatest challenge to conducting comparative effectiveness research in CHD patients are the poor rates of successful transition from pediatric to adult centered cardiology care and high rates of gaps in recommend care for adults with CHD. This study will use PCORnet to examine the effects of gaps in recommended care (cardiology visits) on patient prioritized outcomes for adults with non-complex and complex subtypes of CHD. This system will be established through 14 (12 recruiting) PCORnet affiliated institutions and linkage to the Congenital Heart Initiative registry (https://chi.eurekaplatform.org), the first patient powered registry for adults with CHD. This registry launched in December 2020, and is IRB approved at Children's National Hospital (IRB# Pro00014697). Funded by PCORI, this project will recruit patients at the 12 PCORnet affiliated institutions and will invite them to contribute their health records data and then join the established Congenital Heart Initiative. By enrolling patients and linking their PCORnet (health record) data into an existing adult congenital heart disease (ACHD) specific registry, future interventions to reduce gaps in care based on study findings can be rapidly implemented in real-world settings through the strong partnerships established with key CHD stakeholders.
NCT01830062
The aim of this study is to compare the relationship between the coronary artery calcification assessed by MDCT with the plaque characteristics and necrotic lipid core content of non-intervened coronary segments assessed with near infrared spectroscopy (NIRS) in patients with symptomatic coronary artery disease (CAD).
NCT00819793
The purpose of the study is to evaluate the safety and effectiveness of the CentriMag ventricular assist system to help patients who have experienced heart failure during surgery and cannot be removed from cardiac bypass.
NCT01452152
It is standard treatment to take anti-platelet medication after cardiac catheterization and stent placement to help prevent the formation of blood clots that may cause heart attack or stroke. The most commonly used anti-platelet medicine is clopidogrel (Plavix®). However, researchers have found that people vary in their response to clopidogrel, in part because of differences in their genes. Prasugrel (Effient®)is another anti-platelet medication used to prevent clots. The genetic differences that affect clopidogrel response do not affect prasugrel response. Recently, the FDA added a warning to the label of clopidogrel to notify doctors and patients with certain genetic differences may not get the full benefit from clopidogrel. Despite this, genetic testing for these variations is not usually done in standard medical practice. The purpose of this study is to see if patients with certain gene differences have fewer major cardiac events after stent placement if they are given anti-platelet therapy guided by their individual genetic type compared to standard anti-platelet therapy.
NCT04610775
To determine the impact of overcuffing (using a too-large cuff) and undercuffing (using a too-small cuff) on initial BP and average BP measurements when using an automated BP device, overall and stratified by appropriate cuff size To determine if the impact over- or under-cuffing differs based on the following patient characteristics: 1. Hypertensive (≥140/90 based on triplicate measures using appropriately sized cuff) vs. non-hypertensive. 2. Arm circumference (continuous) 3. Obesity status
NCT02624180
The investigators are studying whether an anti-inflammatory intervention improves impaired coronary endothelial function (CEF) in HIV+ people with no clinical coronary artery disease (CAD).
NCT04133350
This is a prospective, single-arm, unblinded pilot study and registry that aims to demonstrate adherence to adaptive servo-ventilation (ASV) therapy in patients with moderate to severe sleep disordered breathing who have been recently hospitalized. ASV therapy has been linked to improved outcomes in this population, but adherence to therapy is low. The AirCurve 10 ASV device that will be used for this study employs newer technologies, such as web-based monitoring and provides patients feedback, which may increase therapy adherence and therefore improve patient outcomes.
