Active clinical trials for "Heart Diseases"

This research is being done to evaluate the short term and long term effects of ketogenic diets on measures of cardiovascular health. Such measures include cholesterol levels, blood pressure, weight, and thickening of the blood vessel wall over time. Adults aged 18 or older who are already on a ketogenic diet for at least 12 months or who are interested in beginning on the modified Atkins diet may join.

Rheumatic heart valve diseases are prevalent among the young people in Egypt secondary to the socioeconomic conditions. The goal of anesthetic management of these patients is maintenance of sinus rhythm, systemic blood pressure, preload, coronary perfusion, and cardiac output. Many women still prefer general anesthesia rather than regional techniques at the author's country. The pharmacological modifications of the sympathetic response to tracheal intubation and surgical stimulation using opioids have adverse effects on the neonatal outcome after cesarean delivery. The authors have demonstrated in their previous studies the safety of both perioperative infusion of both of ketorolac and lidocaine in the attenuation of the hemodynamic and hormonal responses of tracheal intubation and surgery during cesarean delivery with favorable neonatal outcome and without added risk of perioperative bleeding. Therefore, the authors reported successful anesthetic management of a parturient with infective endocarditis on top of rheumatic mitral valve disease with use of paracetamol-lidocaine-ketorolac-propofol anesthesia. The investigators hypothesize that the perioperative use of ketorolac-lidocaine would reduce the maternal hemodynamic responses to intubation and surgery without any harmful effects on mother or baby during uncomplicated cesarean delivery in the parturients with valvular hear diseases. The investigators are aiming to compare the effects of ketorolac-lidocaine and fentanyl on surgical stress responses, intraoperative fentanyl and vasoactive drugs consumption and neonatal outcome during cesarean delivery in the parturients with valvular hear diseases.

The aim of the study is to clarify whether the perioperative release of the cardiac biomarkers troponin I, troponin T and CK-MB consistently correlate with visualizable myocardial damage, and to what extent these biomarkers are comparable by means of their kinetics and dynamics. Due to the uncertainty regarding the validity of cardiac biomarkers in the diagnosis of myocardial infarction, the answer to these questions could have a considerable influence on internationally valid guidelines and definitions. International studies, especially in the field of coronary surgery and coronary artery disease treatment refer to these definitions, in particular, the adequate treatment of affected patients is directly dependent on them.

This study aims to investigate the potential of using hyperpolarized [1-13C]-pyruvate magnetic resonance imaging (MRI) to assess metabolic alterations in patients with ischemic heart disease (IHD). Altered myocardial metabolism is recognized as a crucial factor in heart failure and IHD, and modulating cardiac metabolism offers a new approach to treatment. However, current diagnostic modalities use ionizing radiation and have shown limited prognostic value. Hyperpolarization through dynamic nuclear polarization (DNP) enables highly sensitive in vivo detection of metabolic processes. Hyperpolarized [1-13C]-pyruvate allows visualization of glycolysis-related metabolism, providing insights into the breakdown of glucose and its derivatives. By using this technique, the study aims to differentiate viable from non-viable myocardium in patients with IHD. The objectives include implementing hyperpolarized [1-13C]-pyruvate cardiac MRI to image metabolic flux in the human heart and investigating the potential of this method to distinguish viable from non-viable myocardium in patients with IHD. The study endpoints involve assessing metabolic flux through the pyruvate dehydrogenase complex (PDC) and analyzing ratios of different metabolites, which can indicate the extent of pyruvate oxidation and lactate production. A cross-sectional study design involving patients with CHF and ischemic heart disease will be used. Patients will undergo hyperpolarized [1-13C]-pyruvate MRI, PET imaging, late gadolinium enhancement (LGE) MRI, and cardiac magnetic resonance imaging (CMR). The study will compare [1-13C]-pyruvate MRI findings with PET results, allowing for a correlation between metabolic data and traditional imaging techniques. This innovative approach could provide valuable insights into the metabolic changes associated with ischemic heart disease

Obtain blood samples for generation and maintenance of induced pluripotent stem cells (iPSCs) and genomic/DNA sequencing for biomedical research that will improve the understanding and treatment of pediatric cardiovascular disease

Often, infants struggle to feed orally after surgery for congenital heart disease and may require supplemental feeding interventions at discharge. In this study, the investigators prospectively randomize infants to oral or nasal endotracheal intubation for surgery and assess postoperative feeding success.

Copenhagen Baby Heart Study - Impact (CBHS-I) is an extension to Copenhagen Baby Heart (CBH) which included over 25.000 new-borns in the Copenhagen area between 2016-2018. Based on clinical and subclinical deviations in the examinations in CBH, subgroups of participants will be invited to clinical examinations (echocardiography and electrocardiogram) in early childhood. There will also be a new, targeted inclusion based on certain exposures during pregnancy. The main objectives are to assess the prevalence of congenital and inherited heart disease and, and the development of these during early childhood; examining the association between pre- and postnatal exposure, disease, lifestyle, environmental and genetic factors; continue to establish reference values for echocardiography in Danish neonates and children.

When small children undergo heart surgery with the heart-lung machine, in the past, blood products to help the blood clot such as Fresh Frozen Plasma (FFP) was routinely used in children under 10kg. With blood clot monitoring technology, we feel that it might not be necessary to expose all children to FFP. We want to determine if those children who did not receive FFP bleed more or require more blood products as compared to those who did receive FFP while on the heart lung machine.

The MEA cardiology societies have joined forces to tackle the issue by establishing a tangible real-world data registry in every MEA country. This endeavor has resulted in the development of a multicenter registry called MEA-WCVD, which is being sponsored by each national cardiology society from participating countries. All data gathered will be consolidated into a singular registry for thorough analysis. Country specific analysis will be performed.

The "Cliniques Universitaires Saint Luc" are one of the high specialized center in valvular heart diseases and valvular heart surgery. Aortic stenosis, mitral and aortic regurgitation are the three valve pathology that are mainly frequent and studied. International guidelines in the management of valvular heart diseases are based on few limited old studies, mainly retrospective. And, a matter of concern is staying, about the timing of surgery for asymptomatic patients. A prospective registry will help us to better understand the pathologies and try to better define guidelines criteria for surgery.
