Filter by:Heart scarring, also known as fibrosis, plays a major role in a lot of heart muscle abnormalities. These abnormalities of the heart muscle can lead to major issues such as symptoms of heart failure, dangerous heart rhythm disturbances and even death. However, a lot of these conditions are still not fully understood and treatment options are limited. We here aim to use a new radioactive dye called 68Ga-FAPI to identify patterns and the activity of heart muscle scarring. This radioactive dye is being used in humans particularly in identifying and monitoring cancers and has shown promise in identifying scarring in the heart as well. This will help us not only understand the underlying disease process and risk stratify these patients but also potentially help us develop new targeted therapies that can affect heart muscle scarring. Participants will undergo a baseline MRI scan using this new dye and a plain MRI scan will repeated 12-18 months after to see if there are any changes in the process.
This study aims to evaluate the impact of Sodium-dependent glucose transporters 2 inhibitor Empagliflozin on the exercise capacity,symptoms of heart failure, cardiac function, myocardial remodeling and quality of life of nonobstructive HCM patients with HFpEF.
Hypertrophic cardiomyopathy (HCM) is a genetic disorder characterized by asymmetric hypertrophy of the heart in absence of loading conditions like hypertension. The genetic mutation underlying HCM sets in motion a cascade of functional and metabolic changes ultimately leading to disease. HCM patients often have microvascular dysfunction and myocardial perfusion deficits, of which the aetiology has not been elucidated. Whether these changes are secondary to remodelling or primarily caused by endothelial dysfunction is unclear. As the pathomechanism of HCM is thought to be a cascade of changes, it is important to gain more insight in the perfusion and endothelial function changes throughout different stages of disease: no phenotype, mild phenotype, and advanced HCM phenotype. In this study we aim to investigate these changes in the two most common genetic mutations.
This single-center, prospective, open-label, randomized, controlled clinical trial is designed to assess the efficacy and safety of the Thoracoscopic Morrow procedure in the treatment of hypertrophic obstructive cardiomyopathy. The primary objectives include investigating: Question 1: The efficacy and safety of two surgical modalities in patients presenting with left ventricular outflow tract obstruction and mid-left ventricular hypertrophy. Question 2: The impact of the two surgical procedures on hemodynamics in patients with left ventricular outflow tract obstruction, mid-left ventricular obstruction, and in individuals with or without organic valvular lesions. Question 3: The effects of the two surgical procedures on exercise capacity, quality of life, and long-term prognosis among patients with left ventricular outflow tract obstruction and central left ventricular obstruction, both with and without valvular lesions. Participants will be stratified into two groups. The experimental group will undergo thoracoscopic Morrow surgery, while the control group will undergo median open modified enlarged Morrow surgery.
Hypertrophic cardiomyopathy (HCM) is hallmarked by the presence of left ventricular hypertrophy (LVH) and may present various symptoms including arrhythmia and heart failure. Mutations in the genes related to sarcomeric proteins and metabolic disorders are known causes of HCM. However, it remains required to further explore the prevalence of HCM in the context of Taiwanese' genetic background. Additionally, certain rare diseases that affect the heart, including Fabry disease, cardiac amyloidosis, may present LVH, which makes precise diagnosis among HCM and these diseases more challenging. In this TSOC multi-center registry, we aim to systematically evaluate the clinical, genetic, biochemical features,prevalence, and possible natural course of HCM and relevant rare diseases such as Fabry disease in Taiwan. In the meanwhile, we may also generate the specific "red-flag" signs of Fabry disease in Taiwan.
The purpose of this study is to assess the safety, tolerability, and pharmacokinetics of AZD0233 following single and multiple ascending dose (SAD and MAD) administration in healthy participants.
The goal of this prospective clinical study is improve the diagnosis of Low-flow low-gradient aortic stenosis (LF/LG AS), in patients with co-existing wild-type transthyretin cardiac amyloidosis (ATTRwt). The main question it aims to answer is whether the classic dobutamine-stress echocardiography can be used to determine AS severity in patients with ATTRwt and LF/LG AS This question will be tried to answer by comparing dobutamine stress echocardiography, with the invasively measured aortic valve area (which is considered as the gold standard). In addition we aim to assess the degree of myocardial fibrosis and amyloid infiltration, assessed by light microscopy and cardiac magnetic resonance (CMRI) and evaluation of myocyte mitochondrial function by high resolution respirometry and their relation to AS severity and hemodynamic response to dobutamine.
The Austrian Hypertrophic Cardiomyopathy (HCM) Registry is a prospective, multicenter registry enrolling patients at multiple outpatient clinics across Austria including academic and non-academic centers. Patients will undergo a structured examination process including assessment for symptoms of HCM, past medical history, concomitant medication, family history and the presence of HCM-specific red flags. Furthermore, clinical data derived from electrocardiogram, echocardiography, laboratory analysis, and genetic testing will be collected focusing on a lean variable dictionary and, in addition, specific hypothesis-driven research parameters. All data are entered into an electronic case report form (eCRF) (Phoenix Clinical Trial Management System). In order to perform multicenter analyses, data can be extracted from the eCRF after approval by the steering committee.
Patients presenting with idiopathic dilated cardiomyopathy and left ventricle dysfunction (LVEF <40%), naive of anti-remodeling cardiac medical therapy, will undergo invasive coronary microvascular assessment based on thermodilution. The primary endpoint, namely the left ventricle reverse remodeling, will be assessed after 12 months of optimal medical therapy based on transthoracic echocardiography. The primary endpoint will be evaluated by an independent central core lab. Patients enrolled in the study will be followed for a period of 5 years to monitor their clinical status. During the study period participants may undergo multimodality diagnostic tests including ECG telemetry monitoring, cardiopulmonary exercise testing, cardiovascular cardiac magnetic resonance.
The purpose of this phase Ⅰ study is to evaluate the effect of oral verapamil tablets on the pharmacokinetics of HRS-1893 in healthy subjects.
