Active clinical trials for "Heart Diseases"

The goal of this clinical trial is to test the safety of lab-grown heart cells made from stem cells in subjects with congenital heart disease. The main questions it aims to answer are: Is this product safe to deliver to humans Is the conduct of this trial feasible Participants will be asked to: Agree to testing and monitoring before and after product administration Receive investigational product Agree to lifelong follow-up Researchers will compare subjects from the same pool to see if there is a difference between treated and untreated subjects.

The objective of this randomized clinical trial is to test the effectiveness of a low-cost hybrid remotely monitored parent-mediated and clinic-based multidisciplinary early intervention (EI) for low-income infants with CHD in Brazil. The intervention protocols will be administered according to age modules, families will be monitored weekly. High risk infants also receive supplemental clinic-based interventions according to developmental needs. Controls will receive standard of care and access to early child development and nutrition practices information from the Brazilian Ministry of Health. All infants will be evaluated at within a 42-month follow-up research outpatient clinic, called NeuroCardio Baby at Santo Antonio Pediatric Hospital, of the Santa Casa de Misericordia Hospital Complex, and affiliated with The Cardiology Institute-University Foundation of Cardiology (IC-FUC), Porto Alegre, Brazil.

This trial is a multi-center, randomized, double-blind, placebo, parallel controlled study. Objectively evaluates the curative effect of Huoxin Pills (concentrated pills) intervention on improving the prognosis of patients with coronary heart disease after drug-coated balloon implantation from a functional point of view. Huoxin Pill(concentrated pills), a traditional Chinese medicine, has been prescribed widely in the treatment of coronary heart disease, angina pectoris, and other diseases.440 patients were selected and followed up for one year. The quantitative blood flow score of the target vessel, late lumen loss, MACE incidence, and safety index were observed at 12 months.

This is a randomized trial with a crossover design to investigate the short-term effects of two different dietary patterns on markers of vascular health. A low-carbohydrate diet and a whole-food, plant-based diet will be used. In addition to more traditional markers (cholesterol, blood pressure, inflammation), endothelial progenitor cells and trimethylamine N-oxide will be assessed.

Previous randomized clinical trials have deomonstrated the efficacy and safety of short-term dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI), however, the single antiplatelet agent to be maintained after short-term DAPT was different. Therefore, which antiplatelet agent to be maintained after short-term DAPT needs further invstigations.

Autologous blood transfused at the end of cardiopulmonary bypass will reduce total blood loss 24 hours after surgery and improve mitochondrial oxygen delivery measured by plasma succinate levels. The study design is a prospective randomized interventional trial of transfusion of fresh autologous whole blood versus standard of care expectant management of bleeding during elective cardiac surgery.

Although recommended therapy for patients with ST-segment elevation myocardial infarction is primary PCI, it remains unestablished whether patients with a symptom duration of more 12 hours benefit from acute revascularisation. This study aims to investigate whether acute intervention is superior to subacute intervention in these patients.

Women suffer disproportionately than men from Cardiac Syndrome X ( chest pain in the absence of flow limiting coronary artery stenosis). Coronary microvascular disease is hypothesized to mediate chest pain in this syndrome. This disorder of the small heart vessels (arterioles) compared to the large vessels (arteries) is not diagnosed during routine heart catheterization. This results in delays in diagnosis, missed opportunities for treatment, and likely contributes to the increased death rate from coronary heart disease in women compared to men. Current testing for small vessel disease is performed in the cardiac catheterization laboratory using specialized testing and is not performed routinely. Accordingly, women with this condition are either falsely reassured, or misdiagnosed as another non-cardiac condition. Unnecessary healthcare costs related to re-hospitalization and repeat angiography are incurred, while women are often not initiated on appropriate lifesaving treatment. We and others have demonstrated in randomized controlled trials that therapies that target the endothelium, e.g. statins, ACE inhibitors, and exercise are effective in this condition. Majority of women with Cardiac Syndorme X go undiagnosed. Recent studies have shown significant increased health care costs, morbidity and mortality related to this disease. It is becoming more important to further characterize this group of patients and we hope to do that with our study.

Heart failure is a major cause of death and hospitalization in Canada. Many of the symptoms experienced by patients with heart failure relate to having fluid accumulate in the lungs causing difficulty breathing, swelling in the legs, and an increase in weight. Thus, one of the cornerstones of managing heart failure includes the use of medications known as diuretics that target the kidneys to reduce fluid accumulation via urination. Deciding on the correct dose of this medication can be quite nuanced as under-dosing can lead to accumulation of fluid, and over-dosing can dehydrate patients and potentially result in lightheadedness/fainting and damage to the kidneys. Currently, options for prescribing diuretics for heart failure include 1) giving patients a regular, fixed dose or 2) having patients monitor their daily weight as a surrogate of their fluid status and then take a dose of diuretic based on a pre-prepared scale. The rationale behind the flexible weight-based diuretic scale is that it can potentially detect early fluid accumulation and thus possibly prevent hospitalization or ED visits, and it also avoids over-dosing and potentially dehydrating patients. Currently, it is not clear whether the flexible diuretic regimen is better than the fixed-dose regimen in preventing ED visits, hospitalizations, kidney damage, or death and as such, this pilot study will directly compare the two commonly used regimens in the management of chronic heart failure patients.

The aim of this study is to perform a pilot study investigating the first attempt intubation success rate differing between video laryngoscope nasotracheal intubation and direct laryngoscope nasotracheal intubation. The study population will consist of 60 neonates and infants with congenital heart disease less than 1 year of age who need nasotracheal intubation during general anesthesia for cardiac procedures. Standard nasotracheal intubation will be performed using either a video laryngoscope or direct laryngoscopy. Neonates and infants will be randomly assigned (1:1) to standard video laryngoscopy (with one of the following systems: Storz C-MAC Miller Video Laryngoscope, Karl Storz, Tuttlingen, Germany or Mc Grath Video Laryngoscope, Medtronic, Boulder,USA) or to direct laryngoscopy with one of the following blades: Miller or Macintosh (Heine, Hersching, Germany).
