Filter by:This was a Phase 2 prospective, randomized, crossover study of Flurpiridaz (18F) Injection for PET-MPI in participants referred for evaluation of known coronary artery disease (CAD) or for suspected CAD with intermediate to high pre-test probability (PTP). The objective is to assess the difference and variability between 2 sets of rest images synthesized by the same or 2 different manufacturing processes. Twenty-eight evaluable [participants were enrolled in this study and underwent 2 Flurpiridaz (18F) Injection PET-MPI at rest. Each participant attended a Screening Visit at least 2 days and up to 14 days prior to the first Flurpiridaz (18F) Injection PET-MPI. The participants were randomized 1:1:1:1 to 4 possible sequences of receiving 2 doses of Flurpiridaz (18F) Injection: 2 groups of 7 participants received 2 Flurpiridaz (18F) Injection doses synthesized by the same manufacturing processes (either HPLC or SPE) and 2 groups of 7 subjects will receive 2 Flurpiridaz (18F) Injection doses synthesized by different manufacturing processes (1 dose by HPLC followed by 1 dose by SPE or 1 dose by SPE followed by 1 dose by HPLC). All participants were followed up by telephone for adverse events (AEs) and serious AEs (SAEs) at 24 (+8) hours following each Flurpiridaz (18F) Injection administration.
Evaluation of the safety and efficacy of the reSept ASD Occluder to treat patients with clinically significant secundum atrial septal defect
The researchers are trying to determine whether a smartwatch and a mobile application, which together deliver activity and goal setting notifications, can increase activity levels for patients enrolled in cardiac rehabilitation.
A 6-month prospective, digital randomized controlled trial targeting approximately 49,000 individuals to evaluate the effectiveness of an influenza vaccination intervention during influenza season for people with cardiovascular conditions
Mechanical ventilation (MV) is used to reduce work and reverse or prevent fatigue of the respiratory muscles, decrease oxygen consumption and maintain gas exchange. In addition to the benefits given to patients undergoing MV, there is a high risk of accumulating bronchial secretions, related to pathology and / or therapeutic intervention. Pulmonary hyperinflation is widespread in patients in intensive care centers (ICUs) as a bronchial hygiene therapy, being used in 40% of 64 Australian ICUs as demonstrated by Dennis et al., Through contact with physical therapists. Mechanical hyperinflation associated with tracheal aspiration is able to increase the amount of secretion aspirated when compared to isolated aspiration in patients undergoing mechanical ventilation. To assess whether the pulmonary hyperinflation maneuver with the mechanical ventilator, compared to isolated tracheal aspiration, increases the removal of secretions. To evaluate whether the use of the pulmonary hyperinflation maneuver in the mechanical ventilator is hemodynamically stable through the collection in two moments of the variables of heart rate (HR), mean arterial pressure (MAP), peripheral saturation (SpO2), respiratory rate (RF) that will be analyzed from the postoperative unit's multiparametric monitor. Evaluate the change in respiratory mechanics through collection in two moments after the mechanical hyperinflation technique through dynamic compliance (Cdyn), tidal air volume (VAC), peak pressure (Ppico). The population will consist of patients from the Post-Operative Unit (UPO), from the Institute of Cardiology, of both sexes, over 18 years old, mechanically ventilated and the sample consisting of 50 individuals. These will be submitted to the use of the pulmonary hyperinflation maneuver in the mechanical ventilator. Randomized crossover clinical trial.
The hypothesis is that there is a significant difference in anxiety scores between intervention and usual care group after intervention. The aim of Heart & Mind Trial is (I) to determine the type of anxiety in cardiac patients and (ii) to investigate the effect of individual cognitive behavioural therapeutic intervention to reduce anxiety in patients with cardiac disease and anxiety compared to usual care.
Positive intra-thoracic pressures induced by mechanical ventilation can negatively impact right heart hemodynamics by restricting systemic venous return and increasing right ventricular afterload. These consequences may be detrimental in patients with a restrictive right ventricular physiology and in patients with single ventricle physiology. NAVA (Neurally Adjusted Ventilatory Assist) ventilation decreases intra thoracic pressures compared to conventional ventilation modes. Brain perfusion is both a hemodynamic indicator and a prognostic factor in cardiac postoperative care. Diffuse Correlation Spectroscopy (DCS) coupled with Near Infrared Spectroscopy (NIRS) is a new technology that allows monitoring, in addition to brain tissue oxygenation, changes in brain blood flow. This physiological study aims to evaluate the impact of NAVA mode ventilation on cerebral and systemic hemodynamics in post-operative cardiac surgery patients with preload dependant right ventricle or with passive venous return to the lungs . This prospective cross-over study will include 30 patients. Once stabilized in intensive care, patients will undergo 2 periods of ventilation in NAVA mode and conventional mode separated by a 30-minute washout period, in a random order. For each period the following information will be collected: changes in cerebral blood flow and cerebral oxygenation, hemodynamic parameters including cardiac output and oxygen transport and ventilatory parameters.
The purpose of this study is to assess the effect of artificial intelligence algorithms on image quality in echocardiography.
Premature coronary heart disease (CHD) refers to the onset of myocardial infarction in men < 55 years old, women < 65 years old. At present, researches on early-onset coronary heart disease mostly focus on its risk factors and clinical characteristics, but there is no relevant research on the relationship between early-onset myocardial infarction and atherosclerosis.
Congenital heart disease (CHD), the most common birth defect, is present in nearly 1% of the population. CHD patients are associated with intense resource utilization and premature death in adulthood. The risk of premature death is linked with reduced exercise capacity, a finding consistently noted in youth with CHD. Reduced exercise capacity in this population has also been associated with reduce physical activity and health-related quality of life. Cardiac rehabilitation (CR) in adults with acquired heart disease is an established secondary prevention strategy that improves exercise capacity. The investigators propose a prospective clinical trial of a home-based high intensity interval training (HIIT) program using a novel telemedicine-equipped video game-linked cycle ergometer (MedBIKE™) for 10 to 18 year olds with repaired moderate-complex CHD. The pilot study with the MedBIKE has shown promising results. The investigators now seek to study the efficacy of this program in a broader CHD population.
