Filter by:The Electronic Medical Records and Genomics (eMERGE) Network is in its third phase and during this time is enrolling and sequencing 25,000 individuals on a custom sequencing panel of clinically relevant, actionable genes. The genetic results will be returned to participants and outcomes tracked through the electronic health records.
Cardiovascular diseases are the most common cause of death in the western world. Myocardial infarction pathogenesis usually involves the development of an atherosclerotic plaque and thrombus. Past research has shown a correlation between thrombin generation values and ischemic heart disease, however, to our knowledge no investigation has been done into the correlation of thrombin generation and cardiac catheterization results in ischemic heart disease patients. In the current research the investigator will investigate the correlation of thrombin generation values using calibrated automated thrombogram and cardiac catheterization results in active ischemic heart disease patients.
This trial will compare the procedural success rate between right and left radial approach in patients undergoing coronary angiography and coronary intervention.
Enrollment: - Patients with stable coronary artery disease (SCAD) and moderate coronary artery stenoses (30-70 %) - Patients with acute myocardial infarction and moderate stenosis of non-culprit arteries (NCL; BYSTANDER LESION) Aims: - To assess the diagnostic accuracy of dobutamine stress echocardiography (DSE) and invasive fractional flow reserve (FFR) measurement - To assess the prognostic impact of reclassification by a mismatching negative test Hypothesis: - DSE and FFR have similar prognostic value in both clinical settings (SCAD and NCL) - Considering the strong negative predictive value of both DSE and FFR, one negative test is sufficiently enough to defer revascularisation, even in the case of mismatch
Congenital heart disease (CHD) is the most common congenital malformations. The right ventricle in the sub-aortic position, or "systemic right ventricle" is one of these complex cardiac diseases. Several studies show that adults with CHD and especially systemic right ventricle have reduced exercise capacity. In addition, studies have shown that there is a correlation between alteration of aerobic physical capacity and alteration of right ventricular systolic function. Understanding and assessing the determinants of the physical capacity of patients with systemic right ventricles and evaluating their quality of life could allows us to improve their therapeutic management and also to expand patient indications to a program cardiac rehabilitation. This can benefit them on their exercise capacity, their tolerance to exercise and their quality of life. The aim is to study the correlation between the quality of life and the aerobic physical fitness of patients with a systemic right ventricle and to determine the clinical and paraclinical parameters that have an impact on the aerobic physical fitness of these patients. The quality of life of patients with a systemic right ventricle will be compared to that of the general population.
The aim of this study is to investigate engagement, motivation, and the barriers to adherence of virtual reality based therapy (VRBT) in patients with cardiac diseases and risk factors to the development of cardiac diseases. In addition, to investigate autonomic and hemodynamic responses of VRBT in comparison with conventional therapy (CT). To do this, patients with cardiac diseases or risk factors will be invited to perform CT or VRBT+CT. They will be submitted to an initial evaluation, and then will be random allocated to 12 weeks of intervention and to a final evaluation. The primary outcomes includes engagement, motivation, barriers and adherence in the 12 previous weeks using questionnaire, after 12 weeks of the intervention and after 12 weeks of the final intervention program. Hemodynamic and autonomic responses will be considered the secondary outcomes being evaluated before, during and after a session at the first, sixth and twelfth week.
With this project the investigators aim to investigate whether premature ventricular complexes (PVC) have a prognostic significance in persons without structural heart disease. Further the investigators look at the possible connection between PVC-morphology and clinical outcome and investigate whether advanced cardiac imaging-methods may identify subtle signs of heart disease in PVC-patients with normal findings at echocardiography.
Acute normovolemic hemodilution (ANH) has long been employed for reducing allogenic blood transfusion for cardiac surgery, and hydroxyethyl starch has been used as an intravenous replacement fluid during ANH procedure. However, possible impact of ANH employing HES on blood viscosity and oxygen delivery have not been well investigated in patients undergoing off-pump coronary artery bypass (OPCAB) surgery . Anesthesia is induced and maintained by using propofol-remifentanil-rocuronium in OPCAB surgery (n=21). ANH is performed by using 5 ml/kg of blood salvage and administering 5 ml/kg of balanced HES 130/0.42 (Tetraspan™) for 15 min during vascular graft harvesting. For the present study, three arterial blood samples (3 ml each) are taken before (Sample 1) and after ANH (sample 2 and 3) and they are stored in 3 tubes. Sample 3 (in tube) undergoes further 30% in-vitro dilution by adding 1-1.5 ml HES. By using a scanning capillary tube viscometer (Hemovister™), Blood viscosity at low shear rate (5/sec) of the three samples are determined. By using a formula with blood viscosity and hematocrit, tissue O2 delivery index (TODI, = hematocrit/viscosity at 5/sec) is calculated.
The investigators are interested in determining the best surgical technique to correct functional mitral regurgitation, as there is currently not one technique that is established to work better than the other. The technique used in current clinical practice is undersizing mitral annuloplasty (UMA), in which a prosthetic ring is implanted onto the mitral valve to correct the leakage. Though widely adopted, durability of the repair is less, as 58% of the patients present with recurrent FMR within 2 years. There are no specific algorithms to predict who might have UMA failure, but research indicates that some geometric indices might be strong predictors. The investigators are interested in testing the hypothesis that, elevated lateral inter-papillary muscle separation (IPMS) is a predictor of post-UMA recurrence of FMR at 12 months. In the first part of this study, the study team will measure lateral IPMS before surgery, and relate to post-surgery FMR severity at discharge/30 days, 6 months and 12 months. A relatively newer technique is papillary muscle approximation (PMA), in which a suture draws together the two muscles that connect the mitral valve to the heart muscle prior to performing UMA. This reduces the lateral inter-papillary muscle separation (IPMS) and is expected to improve the durability of UMA. In the second part of this study, the investigators will perform PMA and UMA together and determine if FMR severity is reduced at discharge/30 days, 6 months and 12 months.
Children with congenital heart disease are at risk for neurodevelopmental disorders, these disorders impacting their quality of life and their integration into society. The aim of this study is to detect neurodevelopmental disorders in children (aged from 6 to 66 months) with congenital heart disease in Nord-Pas-De-Calais (France) and to evaluate the frequency and risk factors of these neurodevelopmental disorders for a better follow-up. This study will help implementing a specific program for the evaluation and management of neurodevelopmental disorders in children suffering from congenital heart disease in Nord-Pas-De-Calais and more globally, in the region Hauts-De-France.
