A Study to Test Vicadrostat (BI 690517) Taken Together With Empagliflozin in People With Type 2 Diabetes, High Blood Pressure, and Cardiovascular Disease
This study is open to adults with type 2 diabetes, high blood pressure, and cardiovascular disease. People can join the study if they have these conditions and do not have a history of heart failure. The purpose of this study is to find out if a medicine called vicadrostat, when taken with empagliflozin, helps reduce cardiovascular risk in people with these conditions. The study will compare this combination to a placebo version of vicadrostat with empagliflozin. Participants are put into 2 groups randomly, which means by chance. One group takes vicadrostat and empagliflozin tablets, and the other group takes placebo tablets with empagliflozin. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants take a tablet once per day for 2 and a half years and up to 4 years and 3 months. All participants also continue their medication for type 2 diabetes, high blood pressure, and cardiovascular disease. Participants have an equal chance of receiving the study medicine or placebo. Participants are in the study for up to 4 years and 3 months. During this time, they visit the study site regularly. During these visits, doctors collect information about participants' health and take blood samples. The doctors document when participants experience cardiovascular events. The doctors also regularly check participants' health and take note of any unwanted effects.

A Polypill for Acute Coronary Syndrome (PolyACS)
The current study aims to investigate whether combining the standard medications prescribed after acute coronary syndrome (ACS)-aspirin, P2Y12 inhibitors, and statins-into a single polypill can improve outcomes following an ACS event. Although these therapies are effective, gaps in adherence and uptake significantly contribute to risk or adverse events in the post-ACS period. This study is designed as a pragmatic, multi-center, randomized trial to assess the feasibility and effectiveness of a polypill-based strategy for treatment of ACS.

The Effect of Adiposity on Muscle and Microvascular Function in HFpEF
This project is an observational study in patients with heart failure with preserved ejection fraction (HFpEF) who are candidates for treatment with weight loss medication to manage obesity or diabetes as part of their standard clinical care. This study will include multiple experimental visits before and after treatment (minimum 7 percent weight loss, between 9-12 months) to understand how increased adiposity and inflammation effects skeletal muscle and cardiovascular health and function and to examine the effect of medically directed weight loss on skeletal muscle health and exercise tolerance. The objective of this study is to 1. Define the mechanisms by which adiposity impairs exercise hemodynamics, microvascular function, and oxygen transport/utilization in patients with HFpEF. 2. Determine if intensive medically directed weight loss can reduce microvascular inflammation and normalize exercise hemodynamics. 3. Quantify the effect of medically directed weight loss on skeletal muscle function and catabolism. Hypotheses 1. Perfusion of subcutaneous adipose tissue disrupts blood flow distribution and impairs muscle microvascular perfusion and exercise hemodynamics. 2. Extramyocellular muscular lipid deposition and microvascular endothelial inflammation is associated with reduced capillarity and impaired microvascular perfusions, while intramyocellular triglyceride content is associated with poor skeletal muscle oxidative capacity, 3. Intensive weight loss will improve exercise hemodynamics, microvascular perfusion, and reduce muscular inflammation, and resistance training will augment these effects.

Optical Coherence Tomography Angiography in Neurological Disease
Optical Coherence Tomography Angiography (OCTA) is a non-invasive tool that images the neurovascular structures of the eye by using near-infrared light. Previous literature has demonstrated the potential of OCTA as a screening tool in stroke, but its utility in other neurological illness such as intracranial hemorrhage is unclear. Hence, this pilot study will gather preliminary data to support future grant applications to investigate this area more fully by recruiting patients with neurological illness and healthy controls and comparing their OCTA imaging parameters.

HIV+ Deceased Donor Heart Transplant Study for HIV+ Recipients
This will be a prospective single-center interventional trial to compare the outcomes of HIV-positive heart transplant recipients by the HIV status of the donor; HIV-positive vs. HIV-negative and learn whether heart organ transplantation from HIV+ deceased donors is as safe and effective in HIV+ recipients as transplants from HIV- deceased donors. Patient will undergo standard evaluation for eligibility of transplantation by the primary heart transplant team. If patient meets eligibility criteria, they will be informed about the study and consent will be obtained. Informed consent will be obtained in a private clinic or inpatient hospital room in a confidential setting. HIV-positive or HIV-negative offers will be made by Organ Procurement and Transplantation Network (OPTN) (serving as a means of "natural randomization" and this information will also be collected, along with the information regarding any information for primary offer declines from the patients as well as other clinical indications to decline an organ offer. As a result of this, there will be two main groups in the study participants that will undergo analysis: 1. patients/recipients that are HIV+ who receive an organ from an HIV+ donor (HIV D+/R+ group) 2. patients/recipients that are HIV+ who receive an organ from an HIV negative donor (HIV D-/R+ group) Only study participants will be able to receive organ offers from both HIV-positive and HIV-negative organ donors whichever is available first regardless of HIV status. This is the only study intervention. Baseline visit parameters will be obtained during a routine heart transplant visit. There will be no additional procedures or blood collection after the baseline study visit. Study data will be collected from chart review of routine post-transplant follow-up visits at weeks 52 (1 year), 104 (2 years), and 152 (3 years) after the transplant.

The Modulatory Effect of Female Sex Hormones on Spinal Neuroplasticity (TMSpine)
The goal of this project is to test our central hypothesis that the spinal cord neuroplasticity in females will be modulated by the level of estradiol concentration. under aim 1 we will determine the influence of estradiol fluctuations on spinal circuit excitability post afferent (sensory) mediated subthreshold motor priming in young healthy females and males. We will use an established repetitive peripheral nerve electrical stimulation with a stimulation intensity below the motor threshold to prime the spinal motor circuits. under aim 2 we seek to characterize the input output property of spinal circuit excitability after descending drive (motor) mediated priming in young healthy male participants. in aim 3 we will examine the influence of estradiol fluctuations on descending drive mediated motor priming in young healthy females.

The ROle of Compression StocKings in Heart Failure Patients (ROCK-HF)
Congestive heart failure (CHF) occurs when the heart is weak and not able to effectively pump blood to the body. One of the common manifestations of CHF is fluid overload and swelling of the legs. Diuretics or "water pills" are usually the treatment for fluid overload and leg swelling; however, in some patients' diuretics are no longer effective or the effectiveness is limited due to poor kidney function. The presence of chronic swelling of the legs could potentially damage the veins; additionally, it could lead to chronic skin changes in the legs and in the worst cases to a leg ulcer. Compression stockings are used in patients with venous diseases to reduce the swelling of the legs and improve mobility and quality of life. Although, there is a theoretical risk that compression stockings might push the fluid of the legs back to the heart and lungs worsening the CHF. The purpose of this study is to determine whether the use of knee-high tight socks (tight stockings with strong compression) vs. knee-high soft socks (soft stockings with minimum compression) are effective in preventing swelling and skin changes and safe in patients with CHF. During the first visit (in-person) a routine medical test will be performed including blood tests, review of the medication doses, current weight, an ultrasound images of the veins, (venous reflux ultrasound), questions about health status and a brief physical exam. The participants will be randomly assigned to receive tight compression vs. soft compression socks. Participants will be asked to wear the socks at least 8 hours a day for 5 days a week. There will be a total of 3 virtual visit (by video or telephone); the first one after one week, then after one month and two months. During the virtual visit participants will be asked about symptoms, current medications and doses, and current weight. The participants are expected to return to the clinic after 3 months for a second in-person visit. During this visit the investigators will ask questions about participant's health, they will perform a brief physical exam of their legs, and check participants weight and medicines; also, a venous ultrasound of the legs, questions about health status will be performed. The duration of the study is 3 months.

Efficacy of LoDoCo in Improving Exercise Capacity Among Patients With HFpEF and Inflammation
The purpose of this research study is to determine the effectiveness of low dose colchicine (LoDoCo) on measures of exercise capacity, physical function, frailty, and quality of life, among patients with heart failure with chronic stable preserved ejection fraction (HFpEF) and systemic inflammation. The use of LoDoCo in this study is considered investigational as it has not been approved by the Food and Drug Administration (FDA) for the treatment of exercise capacity in patients with HFpEF. Participants will undergo a 1-day screening that includes a blood draw and physical examination. If deemed eligible for the study, participants will undergo a baseline visit within 2 weeks of screening visit that includes physical examination, exercise testing, echocardiography and completion of quality-of-life surveys. Participants will also be randomized at this visit (randomly assigned to a group) to receive either LoDoCo or placebo (inactive substance) for 3 months. Participants will be called back at 3 months for repeat physical examination, blood draws, echocardiography, exercise testing and completion of quality-of-life surveys. Each visit will take about 3 hours. Total study duration is about 3 months.

Safety, Efficacy, and Pharmacokinetics of Tafamidis in Patients With Transthyretin-mediated Amyloidosis Post Orthotopic Heart Transplantation
Transthyretin cardiac amyloidosis (ATTR-CA) is a relentlessly progressive disease that can progress to end stage heart failure, at which point recently approved transthyretin production silencing or structure stabilizing therapies provide no clinical benefit. For well-selected individuals, heart transplantation is an excellent therapeutic option to improve survival. Historically, concomitant liver transplantation has been used to halt the progression of non-cardiac transthyretin amyloidosis (ATTR) manifestations, especially for individuals with TTR genotypes associated with significant neuropathy. However, despite this, patients continue to experience progressive non-cardiac manifestations, particularly gastrointestinal and neuropathic, which can have a substantial influence on post-heart transplantation morbidity. Concomitant liver transplantation is also associated with substantial morbidity and its future therapeutic role is questionable with recently established therapies for ATTR. Therefore, there is a clear unmet need to determine the utility and safety of ATTR targeted therapies for patients with recent heart transplantation for end-stage ATTR-CA. The central hypothesis of this proposal is that in patients who have received a heart transplantation for end-stage ATTR-CA, tafamidis therapy will be efficacious and well-tolerated. We aim to determine the safety and efficacy of tafamidis in stable patients who have undergone heart or combined heart/liver transplantation for ATTR (wild-type or variant) cardiac amyloidosis. The proposed study will be a single-arm intervention clinical trial with tafamidis. Because of the efficacy of tafamidis for both variant ATTR-CA and wild-type ATTR-CA, there is no clinical equipoise for an inactive-comparator placebo arm. The primary endpoint of this study will be serial change in plasma transthyretin (TTR) levels from baseline to 12 months at 3-month intervals. The secondary endpoints of this study will include serial changes in neuropathy assessments, modified body mass indices, incident transplant-specific adverse events, and pharmacokinetics of tafamidis. Observations from this study will establish the role of tafamidis use for the management of ATTR in patients after transplantation for end-stage ATTR-CA.

Subclinical Transthyretin Cardiac Amyloidosis in V122I TTR Carriers
Approximately 1.5 million of the 44 million Blacks in the United States are carriers of the valine-to-isoleucine substitution at position 122 (V122I) in the transthyretin (TTR) protein. Virtually exclusive to Blacks, this is the most common cause of hereditary cardiac amyloidosis (hATTR-CA) worldwide. hATTR-CA leads to worsening heart failure (HF) and premature death. Fortunately, new therapies that stabilize TTR improve morbidity and mortality in hATTR-CA, especially when prescribed early in the disease. However, hATTR-CA is often diagnosed at an advanced stage and conventional diagnostic tools lack diagnostic specificity to detect early disease. The overall objectives of this study are to determine the presence of subclinical hATTR-CA and to identify biomarkers that indicate amyloid progression in V122I TTR carriers. The central hypothesis of this proposal is that hATTR-CA has a long latency period that will be detected through subclinical amyloidosis imaging and biomarker phenotyping. The central hypothesis will be tested by pursuing 2 specific aims: Aim 1) determine the association of V122I TTR carrier status with CMRI evidence of amyloid infiltration; Sub-aim 1) determine the association of V122I TTR carrier status with cardiac reserve; Aim 2) determine the association between amyloid-specific biomarkers and V122I TTR carrier status; and Sub-aim 2) determine the association of amyloid-specific biomarkers with imaging-based parameters and evaluate their diagnostic utility for identifying subclinical hATTR-CA. In Aim 1, CMRI will be used to compare metrics associated with cardiac amyloid infiltration between a cohort of V122I TTR carriers without HF formed by cascade genetic testing and age-, sex-, and race-matched non-carrier controls. For Sub-Aim 1, a sub-sample of carriers and non-carrier controls enrolled in Aim 1 will undergo novel exercise CMRI to measure and compare cardiac systolic and diastolic reserve. Aim 2 involves measuring and comparing amyloid-specific biomarkers in V122I TTR carriers without HF with samples matched non-carriers (both from Aim 1) and individuals with symptomatic V122I hATTR-CA from our clinical sites. These biomarkers detect and quantify different processes of TTR amyloidogenesis and include circulating TTR, retinol binding protein 4, TTR kinetic stability, and misfolded TTR oligomers. Sub-aim 2 will establish the role of these biomarkers to detect imaging evidence of subclinical hATTR-CA disease.
