Sarcopenia in Older Patients Hospitalized for Acute Heart Failure.
Acute heart failure (AHF) is the leading cause of hospitalization in people over 65, with the group with preserved ejection fraction (HFpEF) being the most closely related to aging. Among its comorbidities, sarcopenia stands out, and its assessment requires measurement of muscle mass. Muscle ultrasound is an accessible and economical …
18F-mFBG Imaging for Myocardial Sympathetic Innervation
This is a Phase 2 study evaluating the positron-emitting radiopharmaceutical 18F-mFBG as an imaging agent for quantification of myocardial sympathetic innervation. The study will examine a group of stable patients with heart failure (HF) from ischemic cardiomyopathy. All subjects will have left ventricular ejection fraction (LVEF) ≤35% and implantable cardioverter-defibrillators …
Clinical Study of Coronary Extension Catheter
This prospective, multicenter, single-arm study plans to enroll 69 subjects. Subjects meeting the protocol criteria will receive treatment with coronary extension catheters. The safety and efficacy of these catheters in percutaneous coronary intervention will be assessed through the collection and analysis of efficacy and safety endpoints during treatment and follow-up.
Vascular Complications After Kidney Transplantation
To determine the incidence of arterial inflow problems and venous outflow problems as causes of impaired renal function and/or treatment-resistant hypertension after kidney transplantation, when all kidney-transplant recipients in Denmark are evaluated according to uniform, well-defined clinical criteria. To investigate the efficacy and safety of catheter-based balloon treatment (percutaneous transluminal …
Urinary Chloride and Sodium Changes and Residual Congestion in Acute Heart Failure
The goal of this observational study is to learn how changes in urinary sodium and chloride levels relate to fluid overload and short-term outcomes in patients hospitalized with acute heart failure (AHF). The main questions it aims to answer are: Do changes over time in urinary sodium and chloride reflect …
A Study of Metformin to Improve Cardiac Function After LVAD Implantation
This study investigates whether metformin, compared with placebo, improves cardiac function in patients after Left Ventricular Assist Device (LVAD) implantation. Metformin is a widely used oral medication for type 2 diabetes, but emerging evidence suggests it may have beneficial effects on cardiac metabolism and function independent of its glucose-lowering effects. …
Post-Marketing Clinical Study of High-Pressure Cutting Balloon
This study is designed as a prospective, multicenter, 1:1 randomized controlled trial. It plans to enroll 280 patients with moderate-to-severe calcified coronary lesions who are candidates for IVUS-guided DES implantation. Subjects will be randomized in a 1:1 ratio to the experimental group (n=140) or the control group (n=140). The primary …
pCAD-POAF 3 Year Follow-up
This study will include the subjects who enrolled in pCAD-POAF trial (NCT05009914) to observe clinical outcomes 3 years after surgery. The primary outcome is the time to first occurrence of a composite of all-cause death, stroke, systemic embolism, myocardial infarction, unplanned cardiac rehospitalization, or post-discharge atrial fibrillation from randomization through …
Coronary Flow During Rapid Heart Rates
The goal of this observational study is to learn about the factors which determine how well ventricular tachycardia (VT) is tolerated. The main questions it aims to answer are: What impact does coronary artery disease have on the ability for a patient to tolerate VT? Does treatment of coronary artery …
Development of Novel Physiological CMR Methods in Health and Disease
Physiological cardiovascular stress test plays a crucial role in the assessment of patients with suspected heart disease. There are several methods of cardiac physiological stress tests and each of them offer varied insight into cardiac physiological adaptation: passive leg raise, intra-venous fluid challenge, pharmacological stressors and physical exercise stress test. …
