The purpose of the Atherosclerosis Risk in Communities (ARIC) Study - ARIC Generation 2 research study is to evaluate the link between glucose and heart problems in adults with type 2 diabetes. Heart problems can be common in people with type 2 diabetes. We are interested in measuring your blood sugar (glucose) using a continuous glucose monitor and monitoring your heart rhythm at the same time.

This study aims to identify independent blood-based risk factors for postoperative complications and near-term events among patients undergoing CABG surgery. In particular, this study will be using proteomics, the study of all proteins produced by the cells found in blood, as well as genetic analysis to identify potential predictive markers of postoperative complications. We will collect blood samples from before and after surgery. This study does not involve any medical treatment other than the one prescribed by your doctor, nor does it involve any additional medical procedures.

Prospective study to compare safety of upper versus lower extremity injection agitated saline (bubble study) using echocardiography of the heart.

Levosimendan has not been approved by the FDA to treat people who have PH-HFpEF or approved to be taken by mouth (orally). In this study, we will measure the amount of levosimendan in blood at various times and evaluate the change in participants 6-Minute Walk Distance.

The purpose of this research study is to compare the transfusion of cold-stored (refrigerated) platelets to standard room temperature stored platelets. The goal of the trial is to determine whether platelets stored cold are similar or better at stopping bleeding compared to platelets stored at room temperature and, if so, to determine the maximum duration of cold storage that maintains a similar effect on bleeding

Black Americans are 60% more likely to be diagnosed with Type 2 Diabetes (T2D) and 2 times more likely to die from T2D than non-Hispanic White Americans. Recent research has shown that sedentary behavior (such as sitting or lying down) have a significant negative impact on health. We are doing a small study with older people who identify as Black or African American and have T2D to look at ways to reduce sedentary behavior. The study will last about 1-2 months for each participant.

The objective of this study is to evaluate the safety and efficacy of the AccuCinch Ventricular Restoration System in patients with symptomatic heart failure with reduced ejection fraction (HFrEF).

A single visit study with muscle and/or skin biopsy / blood draw, performed to determine whether a molecular or cellular defect can be attributed to cells of Fascioscapulohumeral Muscular Dystrophy (FSHD) muscle. This study is recruiting both individuals with genetically confirmed FSHD as well as unaffected healthy (control) individuals.

We are looking at a new drug called 'ziltivekimab' to see if it can be used to treat people living with heart failure and inflammation. People will get either ziltivekimab or a placebo (inactive dummy drug). The study drug is an injection given into the fold of the skin on the stomach, thigh or upper arm once every month. People will take the study drug for up to 4 years.

The purpose of this study is to determine if replacing the mitral valve without open-heart surgery is as safe and effective as standard mitral valve surgery in patients with similar medical conditions. This system allows a bioprosthetic mitral valve (investigational valve) to be implanted through a long, thin, flexible tube that is inserted through an incision in the side of the chest or through an incision made in the groin area and through a vein in the leg. Participation in the study is expected to last approximately 5 years from the day the valve is implanted.

CREST-2 is a parallel trial to compare carotid endarterectomy + intensive medical management (IMM) vs IMM alone, and carotid artery stenting plus IMM vs IMM alone in patients with asymptomatic carotid stenosis >70%.

This study will compare the effects of apixaban to aspirin in patients who have atrial fibrillation and a recent brain hemorrhage to see which is better in preventing strokes and death.

The study will be a randomized, multicenter, open-label trial with blinded adjudication of outcomes.

The purpose of this study is to establish whether the device, intermittent pneumatic compression (IPC), both with and without walking exercise, can improve the ability to walk and prevent decline in the ability to walk for people with PAD. Intermittent pneumatic compression consists of blood pressure cuffs that are wrapped around the lower legs (below the knees) that inflate three times per minute. These cuffs may improve blood flow to the lower legs and feet.

The purpose of this research study is to assess the effect of a physical rehabilitation program for people admitted to the hospital with a diagnosis of heart failure. After completing baseline tests, participants will be randomly assigned to one of two study groups. Randomization means that you are put into a group by chance. (It is like flipping a coin.) You will have an equal chance of being placed into either group. Participants are assigned to a rehabilitation intervention (treatment) group, or to the attention control group, that will receive usual care.

We are exploring ways to increase physical activity after stroke using a web-based rehabilitation program. The purpose of this study is to adapt the Activating Behavior for Lasting Engagement (ABLE) program using video visits so people with stroke can participate from home.

The goal of this trial is to evaluate the safety and effectiveness of the PASCAL System with optimal medical therapy (OMT) compared to OMT alone in participants with symptomatic severe tricuspid regurgitation. We are studying this in patients who may not be ideal candidates for tricuspid valve surgery (performed via open-heart surgery) and may be eligible for transcatheter tricuspid valve repair (minimally invasive procedure that repairs the valve).

We are trying to learn more about how the brain controls movement and how this affects function after stroke. We expect differences in the side of brain damage to result in distinct movements of each arm. We will collect information with standard clinical exams and movements during tasks completed on the Kinereach virtual reality system. We will compare results between people who have and have not had a stroke.

The purpose of this study is to determine what clinical, electrocardiogram, and cardiac magnetic resonance imaging factors identify patients at risk for developing rapid irregular heartbeats requiring therapy by implantable defibrillator. We expect that participation will last for up to 4 years. The procedures will include wearing a heart monitor (Holter) for 24 hours, obtaining a blood sample for markers of heart disease, and having a cardiac magnetic resonance examination with contrast – a substance given intravenously to make the images better, prior to defibrillator implant. After the initial visit, participation will not require any additional visits since information about the clinical course will be acquired from medical records.

This is a registry study. The Cardiac Sarcoidosis Consortium (CSC) is an international, multicenter partnership among physicians and allied professionals at major medical centers with the unifying purpose to learn more about cardiac sarcoidosis through collaborative research.

Severe aortic valve stenosis can include stiffening and hardening of the heart valve leaflets (tissue that opens and closes in the heart valve) so that the valve cannot work properly. If left untreated, excessive strain put on the heart muscle will eventually cause it to fail or lead to other serious complications. This study is a research project to assess a way of replacing aortic valves without the need for open-heart surgery and without surgically opening the heart to remove the narrowed valve. The device under study is called the ACURATE Transfemoral Aortic Valve System. The study will compare the safety and effectiveness of the ACURATE Valve, along with other commercially available TAVR devices.

To determine if a perioperative infusion of 0.2% ropivacaine via bilateral T3 paravertebral catheters can decrease the incidence of new onset atrial fibrillation following primary CABG and/or valve surgery and compare a number of secondary outcomes.

More than 65% of people with lower extremity peripheral artery disease (PAD) are overweight or obese. Overweight or obese people with PAD have greater functional impairment and faster functional decline than normal weight people with PAD. Walking exercise is first line therapy to improve walking performance in PAD. However, our NHLBI-funded observational longitudinal study of functional decline in PAD showed that overweight and obese PAD participants who combined weight loss with walking exercise had significantly less functional decline than those who walked for exercise but did not lose weight. Therefore, we hypothesize that among people with PAD who are overweight or obese, a weight loss intervention combined with exercise will improve walking ability more than exercise alone. However, the effects of intentional weight loss in overweight or obese people with PAD are unknown and may not be beneficial if weight loss exacerbates PAD-related sarcopenia. Behavior change that achieves sustained weight loss is particularly challenging in older obese people with chronic disease. Therefore, among people with PAD and BMI>28 kg/m2, we will conduct a randomized clinical trial to test the hypothesis that a weight loss intervention combined with walking exercise achieves greater improvement in functional performance than exercise alone at 12-month follow-up.

This study includes healthy adults between 18-70 years old who are either non-smokers or cigarette smokers interested in quitting. The purpose of this study is to learn more about how people respond to stress and to taking one dose of a widely and safely used drug called naltrexone as well as to learn about how these responses relate to whether or not someone smokes, smoking cessation, and smoking relapse.

The goal of this study is to learn more about the effects of menopause on women's blood pressure and heart health. We are looking for women between the ages of 35 and 70 years to participate in the study. Participants may be pre- or postmenopausal; we are specifically interested in evaluating the influence of premature (< age 40 years) and early (< age 46 years) menopause.
