Treatment With the Ketone Body 3-hydroxybutyrate in Patients With Cardiogenic Shock

May 20th, 2022 - Background Cardiogenic shock is a life-threatening state of acute heart failure with severely depressed blood pressure and organ perfusion. The 30-day mortality is reported as high as 50%. To date, no randomized trial has documented a survival benefit of any medical treatment in this patient group. In a first-in-man study the investigators have recently discovered that treatment with ketone bod...

FFR Versus Angiography-Guided Strategy for Management of AMI With Multivessel Disease

May 20th, 2022 - The presence of ischemia is a prerequisite for the improvement of clinical outcomes with percutaneous coronary intervention (PCI). It is well-known that the discrepancy exists between angiographic stenosis severity and the presence of myocardial ischemia. This discrepancy cannot completely overcome with even more precise invasive imaging modalities such as intravascular ultrasound or optical co...

Famine From Feast: Linking Vitamin C, Red Blood Cell Fragility, and Diabetes

May 20th, 2022 - Diabetes type two is a debilitating disease that leads to chronic morbidity such as accelerated microvascular disease. Accelerated microvascular disease may produce blindness, end stage renal disease, myocardial infarction, stroke, and limb ischemia. Strategies to prevent or delay microvascular disease have the potential to improve the lives of millions and prevent catastrophic illness. The maj...

Preventive VT Substrate Ablation in Ischemic Heart Disease

May 20th, 2022 - Fibrotic tissue is known to be the substrate for the appearance of scar-related reentrant ventricular arrhythmias (VA) in chronic ischemic cardiomyopathy (ICM). Late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) has proven to be a useful technique in the non-invasive characterization of the scarred tissue and the underlying arrhythmogenic substrate. Previous studies identified the...

Fixed Dose Flavonoid Isoquercetin on Thrombo-Inflammatory Biomarkers in Subjects With Stable Sickle Cell Disease

May 20th, 2022 - Sickle Cell Disease (SCD) is an inherited monogenic hemoglobin disorder caused by a mutation in the gene encoding the beta globin subunit of adult hemoglobin (HbA) resulting in a substitution of valine for glutamic acid at position 6 and thus producing hemoglobin S (HbS). When deoxygenated, HbS polymerizes, rendering the red cell rigid, viscous, and abnormally adherent to the capillary endothel...

May 20th, 2022 - Fibrotic tissue is known to be the substrate for the appearance of scar-related reentrant ventricular arrhythmias (VA) in chronic ischemic cardiomyopathy (ICM). Late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) has proven to be a useful technique in the non-invasive characterization of the scarred tissue and the underlying arrhythmogenic substrate. Previous studies identified the...

The Effect of Ischemic Conditioning on Strength and Ambulation in Subjects With PAD

May 20th, 2022 - Lower limb amputation is common in the United States, with approximately 150,000 amputations annually. Most individuals walking with a prosthesis demonstrate asymmetrical loading-i.e., they favor the amputated side by placing more weight and increased ground reaction forces through the intact limb-which likely contributes to increased metabolic cost of walking. Lack of adequate muscular strengt...

A Phase II Study of Bevacizumab and Erlotinib in Subjects With Advanced Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) or Sporadic Papillary Renal Cell Cancer

May 20th, 2022 - Background Hereditary Leiomyomatosis and Renal Cell Cancer (HLRCC) is a familial cancer syndrome characterized by a propensity for developing renal cancer, and uterine and cutaneous leiomyomas. The kidney cancer associated with HLRCC is clinically aggressive and is characterized by unique histopathologic features that are sometimes described as type 2 papillary RCC. Germline mutations in the fu...

Ketamine in Patients Undergoing TEVAR Procedures Receiving NCI

May 20th, 2022 - Patients undergoing descending aortic repair often experience post-operative pain, and have high post operative opioid requirements. That pain is partially due to the use of naloxone continuous infusion (NCI). NCI is part of a bundled approach used in the first 48 hours post-operatively to prevent spinal cord ischemia, a devastating complication associated with surgical repair of the descending...

CADASIL Disease Discovery

May 20th, 2022 - Small vessel diseases are conditions characterized by the narrowing of small arteries leading to an imbalance of blood supply upon demand. This results in a progressive chronic hypoperfusion with detrimental outcomes for the affected organ system and for the patient. Recent advances in genetic evaluation have identified several genetic variants causing cerebrovascular small vessel diseases. The...

Evaluating New Radiation Techniques for Cardiovascular Imaging

May 20th, 2022 - Cardiac CT angiography is associated with radiation exposure. Different methods of creating CT pictures have been developed to reduce the radiation dose to the subject. The purpose of this research study is to learn whether these new imaging methods are accurate or predict subject outcomes.

Thrombolysis With Recombinant Non-immunogenic Staphylokinase vs Surgery in Patients With Acute Limb Ischemia FORAT Trial

May 20th, 2022 - Fortelyzin® (the active substance Forteplase) is a recombinant non-immunogenic staphylokinase with high fibrinselective thrombolytic activity. In a multicentre, randomised clinical trial in patients with ST-segment elevation myocardial infarction (FRIDOM), non-immunogenic staphylokinase was administered as a single intravenous bolus of 15 mg in all patients, regardless of bodyweight, and showed...

An International Study to Evaluate Diagnostic Efficacy of Flurpiridaz (18F) Injection PET MPI in the Detection of Coronary Artery Disease (CAD)

May 20th, 2022 - This is a Phase 3, prospective, open-label, international, multicentre study of Flurpiridaz (18F) Injection for PET MPI in patients referred for ICA because of suspected CAD.

Evaluation in STEMI Patients Using FDY-5301

May 20th, 2022 - The purpose of this study is to evaluate the efficacy and safety of FDY-5301 compared to placebo on cardiovascular clinical outcomes in subjects with an anterior ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (pPCI). The study is designed as a randomized double-blind parallel-group comparison of FDY-5301 and placebo. Inclusion and exclusion crit...

Biomechanical Analysis of Arterial Tissue From Patient Suffering From Peripheral Artery Disease in the Lower Limb

May 20th, 2022 - Peripheral artery disease (PAD) is a severe cause of morbidity in patients. Common treatment approaches are too often still unsatisfactory. Angioplasty is commonly followed by restenosis, caused by overloading of the arterial tissue. This study is aimed at improving this treatment approach through the in silico simulation of arterial remodeling after balloon expansion. Such simulations require ...

Pathophysiology of Acute Pain in Patients With Sickle Cell Disease

May 20th, 2022 - Episodic pain is the most common acute morbidity and the leading cause of hospitalization in patients with sickle cell disease. It is caused by microvaso-occlusion induced by sickled red blood cells, an outcome of the polymerization of deoxygenated hemoglobin S (HbS). Factors that contribute to the acute sickle pain include the release of cell-free DNA (cfDNA) and heme that initiate a downstrea...

A Safety and Efficacy Study of Intravenous (IV) Elezanumab Assessing Change in Neurologic Function in Adult Participants With Acute Ischemic Stroke

May 20th, 2022 - Stroke is one of the leading causes death and major functional disability worldwide. Treatment options for acute stroke are limited with many patients having residual neurologic impairment. The purpose of this study is to evaluate the safety and efficacy of elezanumab and assess change in neurologic function in participants following an acute ischemic stroke. Elezanumab is an investigational dr...
