Active clinical trials for "Heart Diseases"

The EXAMINATION trial was a superiority trial that compared everolimus-eluting stents (EES) versus bare-metal stents (BMS) in an all-comer ST-segment elevation myocardial infarction (STEMI) population. The patient-oriented endpoint was not superior at 1-year, but it was at 5-year. However, very-long term follow-up is unknown. The study had an independent Clinical event Committee (CEC). All events were adjudicated by an independent clinical committee, according to the Academic Research Consortium 1.

To assess the feasibility in diabetics in a primary care setting of screening for NAFLD and advanced fibrosis, by using non-invasive magnetic resonance imaging (MRI) to estimate the hepatic proton density fat fraction (MRI-PDFF) and magnetic resonance elastography (MRE) to estimate hepatic stiffness.

Amyloid heart disease is an accumulation of fibrillar proteins in the extracellular sector of the heart. Identified on echocardiography as Ventricular hypertrophy. The investigation of a Left Ventricular hypertrophy (LVH) is the most frequent discovery circumstance of amyloid heart disease. Pathophysiological mechanisms poorly understood, resulting in late diagnosis. Transthyretin amyloid heart disease (CATTR) is the most common form of cardiac amyloidosis in the West Indies due to an abnormally high frequency of the Val122Ile and Val107Ile mutations of the transthyretin gene in this population. Val122Ile and Val107Ile mutated-transthyretin are the substitution of valine for isoleucine at codon 122 of the TTR gene ( V122I) and at codon 107 of the TTR gene (V107I). Complications of CATTR are functional changes in heart cells or even death due to mechanical abnormalities (loss of contractility and increased wall stiffness cardiac arousal and conduction disturbances). These disorders result from an electrical abnormality of the heart the reason why the cardiologist performs preventive performance of electrophysiological explorations with EnSite Precision™. It's a registration system used to detect foci of necrosis within the myocardium. Amyloid deposits are areas devoid of electrical activity. Do they detectable by the EnSite Precision™ recording system ?

Little is known about the status of maternal, obstetric and neonatal complications and the potential predictors of developing heart failure (HF) in the mothers with underlying heart disease (HD) in Southwestern China. Eligible samples were screened from December, 2010 to December, 2019. Maternal clinical characteristics and in-hospital outcomes were collected and compared in women with and without HD, and in HD subtypes: valvular heart disease (VHD), cardiomyopathy, adult congenital heart disease (ACHD), pulmonary hypertension (PH) and other cardiac condition.

The National Tunisian Registry of Valvulopathies is an observational, prospective and multicenter study aiming to assess the epidemiological, clinical and therapeutic profile of valve disease in tunisian departments of cardiology. Cardiologists from both sectors (public and private) are participating in the study, with 37 investigational centers. Data will be captured electronically by DACIMA Clinical Suite, according to FDA 21 CFR part 11 (Food and Drug Administration 21 Code of Federal Regulations part 11), HIPAA (Health Insurance Portability and Accountability Act) & ICH (International Conference on Harmonisation) requirements.

The purpose of this study is to evaluate the prevalence, during the enrolment, of Left Ventricular Dysfunction diastolic and/or systolic in patients with diabetes mellitus type 2 without known or documented heart disease history and recognize its predictive clinical, biohumoral and with non-invasive techniques parameters.

The purpose of this study is to understand the causes of growth failure and to define biochemical markers of nutritional failure in patients with single ventricle Congenital Heart Disease (CHD).

This study is being performed to obtain data about the CORA system, a new device that is currently being tested and is not yet cleared for sale in the United State by the Food and Drug Administration (FDA). The purpose of the study is to validate the CORA system by comparing the results of this test to that of the standard of care device called the TEG system. Both systems evaluate hemostasis, a highly complex and interactive process involving many protein and cellular elements, especially platelets, occurring in a series of interrelated phases, which results in either normal hemostasis or a tendency toward bleeding or clotting complications.

Cardiovascular disease (CVD) is an important public health problem that affects millions of people worldwide. Associations between risk factors, such as smoking, dyslipidaemia or hypertension, and prevalent CVD are well documented. However, few studies have investigated associations with onset of disease. The initial manifestation of CVD, for example an episode of unstable angina, is important because it influences the prognosis, the quality of life and the management of disease. Furthermore, the extent to which social deprivation, alcohol consumption or atrial fibrillation affects presentation of CVD is poorly understood and deserves further consideration. Most previous studies have considered CVD as a single entity. However, differences in aetiology between coronary phenotypes suggest that risk factors may not be shared across specific coronary phenotypes and their relative importance is likely to differ for each phenotype. Gaining knowledge of these differences could provide insights into the pathophysiology of specific forms of CVD and could eventually lead to modification of recommendations for patient management and disease prevention. We propose to use the linkage of the national registry of coronary events to general practice records in the Clinical Practice Research Database (CPRD), to investigate whether demographic, behavioral, and clinico-metabolic risk factors differentially influence the onset of specific types of CVD.

The purpose of this research study is to learn about parents' experiences following diagnosis of a fetal/neonatal Congenital Heart Defect (CHD). Nurses, physicians, and other health-care clinicians will benefit from an improved understanding of what the diagnosis means to parents and what they expect concerning the infant, being a parent, and caregiving tasks and responsibilities. The investigators expect that the knowledge gained will increase clinicians' ability to respond to parents' needs.
