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.

There is evidence that the gut microbes interact with the body’s immune system, and people with pulmonary hypertension may have altered composition of gut microbes. We are studying whether transplanting gut microbes from healthy donors using a treatment called microbiota transplant therapy may have beneficial effects on pulmonary arterial hypertension.

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.

This research is being done to better understand why people develop a type of heart failure where the heart contracts normally but does not relax well. By comparing levels of chemicals in the blood that are secreted by the body in subjects with normal hearts and in subjects with abnormal relaxation, we hope to gain a better understanding of why heart failure occurs.

This study includes healthy adults between the ages of 21-70 who either use or do not cannabidiol (CBD) regularly. The purpose of this study is to learn about how CBD users and nonusers respond to stress. Participants must be willing to attend one in-person visit at the University of Minnesota Duluth campus

The first year after LVAD implant involves a lot of changes to managing life with an LVAD for both the patient and the caregiver (informal or family care partner). Both patient and care partner will enroll in the study so that we can better understand the experiences of each person, including: self-management, emotional wellbeing, care partner experience and quality of life. You will be asked to fill out questionnaires after LVAD implant (at four time-points) over six months. We also ask you to wear a research watch (for ten days) to measure activity and rest. You can do this entire study from your home.

This research study is designed to evaluate a new treatment approach for patients with chronic heart failure. This study will assess the effectiveness and safety of a new medical device, the AquaPass system, in managing the accumulation of fluids in the body that persists despite standard medical treatment. The purpose of this study is to understand if the use of the AquaPass System with medication treatment results in increased fluid removal compared to only regular medication treatment.

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 the study is to assess if the study treatment, pelacarsen, taken by people with mild or moderate CAVS and elevated lipoprotein(a) can safely help slow the progression of calcific aortic valve stenosis (CAVS). Pelacarsen is a treatment being tested that acts on a particle called Lp(a), which if elevated, may play a role in CAVS.

We want to explore whether it is possible for adults without symptoms of heart disease to perform a short, high intensity exercise routine in a clinic setting in order to measure maximum heart rate and heart rate recovery. If this method is successful, it could be used by patients and clinicians to estimate and track heart health over time.

This research is being done to assess whether it is safe and effective to stop oral anticoagulation medications (a blood-thinning medication) during prolonged periods of normal heart rhythm in participants with infrequent episodes of atrial fibrillation (AF).

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.

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.

The objective of this study is to evaluate the safety and feasibility of implantation of the Aria CV PH System in subjects with pulmonary hypertension (PH) and right heart dysfunction. In addition, the study will evaluate early signals of performance of the implanted system.

The purpose of this study is to learn about a new way of managing hypertension using a wireless blood pressure monitor and a smartphone. The goal is to improve hypertension care in older adults with memory loss or mild dementia in partnership with their caregiver.

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.

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.

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).

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 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.
