Active clinical trials for "Heart Diseases"

In this clinical study the investigators will compare blood pressure measurements obtained using the non-invasive, continuous and wireless Biobeat monitoring device (a wrist watch or a patch configuration) to an invasive arterial line (radial or femoral) in 30 patients immediately after cardiac surgery, at the intensive care unit.

Coronary Microvascular Dysfunction has been consistently shown to play a considerable role in pathophysiology of Ischaemia with non-obstructed coronary arteries (INOCA). While the both diagnoses are individually related to remarkably worse outcome, there is no available method to simultaneously determine INOCA-CMD endotypes in vessel level, during the invasive diagnosis. The investigators hereby hypothesize that, combined intracoronary electrocardiogram (IC-ECG) (considering the high sensitivity and specificity of IC-ECG for studied vessel-territory) and intracoronary doppler can simultaneously and successfully identify vessel specific coronary microvascular dysfunction and resulting ischemia, which may potentially enable immediate diagnosis and endotyping of CMD-INOCA subgroups during the invasive assessment of first ANOCA episode, obviating the need for further ischemia-studies such es SPECT, which have considerably higher costs and lower sensitivity. Major coronary arteries of patients aged between 18 - 75 without obstructing coronary artery disease who have previously documented ischemia with non-obstructed coronary arteries (INOCA) via coronary angiogram and myocardial perfusion scan will be evaluated simultaneously with IC-ECG and intracoronary Doppler during rest and under adenosine induced hyperaemia. Performance of the combined system to identify Coronary Microvascular Dysfunction with structural and functional subgroups as defined by abnormal Coronary Flow Reserve (CFR) and Hyperemic Microvascular Resistance (HMR) and Ischemia in downstream territories of same vessel area (as defined by perfusion scan) is intended to be determined. The investigators also intend to interrogate the possible relationship between dynamic changes in IC-ECG parameters and invasively obtained intracoronary hemodynamic data.

Cardiovascular disease (CVD) is the number one cause of death for women over the age of 25, accounting for 1 of every 3 female deaths. Research has shown that while hypertension in women is less controlled, they are also less likely to be identified with ischemic heart disease and when diagnosed treated less aggressively than men. Moreover, women who are diagnosed with breast cancer have an increased risk for cardiovascular disease. The Women's Assessed Cardiovascular Evaluation with MCG (WACE-MCG) study is designed to collect CardioFlux scans on a select group of female volunteers who are Ms. Medicine patients. CardioFlux is used as a noninvasive MCG tool that analyzes and records the magnetic fields of the heart to detect various forms of heart disease. There will be a 12-month duration of the study where we propose to collect screening data from approximately 200 volunteers who present to the Genetesis facility for a 5-minute CardioFlux MCG scan. The volunteers will be contacted at intervals over a 1-year period for follow-up data and may choose whether or not they would like to provide follow-up data or participate in another scan.

This is a post-market, standard of care, real-world observational study to assess the clinical outcomes of the SYNERGY XLV (MEGATRON) Coronary Stent System for the treatment of subjects with atherosclerotic lesion(s) ≤ 28 mm in length (by visual estimate) in native coronary arteries ≥3.50 mm to ≤5.00 mm in diameter (by visual estimate). This Post Approval study is a cohort associated with the Evolve 4.5/5.0 (SYNERGY LV) Post Approval Study, which is registered under ClinicalTrials.gov ID: NCT03875651.

To determine the correct size of endotracheal tubes (ETT) for endotracheal intubation of pediatric patients is no menial task. Although new methods have been investigated to determine ETT size, and the three-dimensional (3D) printing technology has been successful in the field of surgery, there are not many studies in the field of anesthesia. The purpose of this study is to evaluate the accuracy of a 3D airway model for prediction of the correct ETT size, and compare the results with a conventional age-based formula in pediatric patients. : Thirty five pediatric patients under 6 years of age who were scheduled for congenital heart surgery. In the pre-anaesthetic period, the patient's computed tomography (CT) images were converted to STL files using the 3D conversion program. An FDM type 3D printer was used to print 3D airway models from the sub-glottis to the upper carina. ETT size was selected by inserting various sized cuffed-ETTs to a printed 3D airway model.

Depersonalized multi-centered registry initiated to analyze dynamics of non-infectious diseases after SARS-CoV-2 infection in population of Eurasian adult patients.

Use lay language. Current guidelines regarding physical activity in patients with inherited arrhythmia and cardiomyopathy are mostly dedicated to adult patients, with a special focus on sports competition. Their application to the pediatric population has been scarcely evaluated. Physical activity is well known for its health benefits but may be dangerous in this population, which leads to confusion within the medical community and among patients. Actual physical activity of children with such inherited cardiac disorders is unknown. This study aimed to assess the level of physical activity in children with inherited arrhythmia and cardiomyopathy, and the adherence to the current European guidelines on the subject. Secondary objectives aimed to assess through a qualitative analysis the impact of the disease on physical activity and daily life in this population. The level of physical activity and adherence to current guidelines will be determined from interviews between the patient and the principal investigator. Each patient will be questioned in order to explore the experiences, motivations and feelings of participants regarding physical activity. The standardized questionnaire was created by the principal investigator and members of the clinical research team. The investigators believe that many children practice physical activity outside the current guidelines and hope to identify the main determinants of physical activity in this population.

Clinical ultrasound has become essential in emergency medicine. The guidelines are to use of echocardiography in specific contexts: dyspnea, hypotension or chest pain. The evaluation of left ventricle ejection fraction (LVEF) is one of the basic objectives of echocardiography. The reference assessment in emergency medicine is visual assessment. It suffers from poor inter-observer reproducibility. Pocket ultrasound scanners seem to meet the constraints of point-of-care ultrasound. A new tool is available on a pocket ultrasound device: the automatic evaluation of LVEF. Its interest could be to have a better inter-observer reproducibility than visual evaluation.

Background: Neonates and small infants with congenital cardiac disease undergoing cardiac surgery represent major challenges facing pediatric anesthesia and perioperative medicine. Aims: We here aimed to investigate the success rates in performing ultrasound guided central venous catheter insertion (CVC) in neonates and small infants undergoing cardiac surgery, and to evaluate the practicability and feasibility of thereby using a novel wireless ultrasound transducer (WUST). Methods: Thirty neonates and small infants with a maximum body weight of 10 kg and need for CVC before cardiac surgery were included in this observational trial and were subdivided into two groups according to their weight: < 5 kg and ≥5 kg. Cannulation success, failure rate, essential procedure related time periods, and complications were recorded and the clinical utility of the WUST was assessed by a 5-point Likert scale.

The trial will include 75 patients with evident or suspected ischemic heart disease refered to Department of Nuclear Medicine & PET Centre, Aarhus University Hospital, for perfusion imaging by 15O-H2O PET/CT scan of the heart during rest and stress. Instead of the clinical scan participants will undergo perfusion imaging by 15O-H2O PET/MR. The clinician will receive diagnostic information based on the 15O-H2O PET scan as if the patient had not participated in the study. As such, the study has no influence on the diagnostics or treatments of the patient. Data from the scans will be used to compare 15O-H2O PET with cardiac MR for evaluation of myocardial perfusion. Follow up will be done for up to 10 years in regards to major cardiovascular events in order to determine the prognostic value of the scan.
