Filter by:The primary objective of this study is to assess the efficacy of a single dose of ravulizumab IV compared with placebo in reducing the risk of the clinical consequences of AKI (MAKE) at 90 days in adult participants with CKD who undergo non-emergent cardiac surgery with CPB.
Myocardial infarction (MI) is a leading cause of death in developed countries, including Sweden. Standard treatment for patients after MI includes exercise-based cardiac rehabilitation which contributes to improved cardiovascular function and reduces the risk of hospital readmissions, new cardiovascular events and mortality. Thermotherapy may also have beneficial effects on cardiovascular disease by a reduction in inflammatory status and improved metabolism and vascular function. Given the well-documented effects of exercise training on cardiac rehabilitation and recent evidence that thermotherapy may improve cardiovascular function, we wish to investigate the effect of exercise combined with hot water immersion (HWI) in cardiac rehabilitation post-MI. This is a single-centre, randomized controlled clinical trial in patients with recent MI. Our aim is to investigate whether exercise training combined with HWI improves inflammatory and metabolic status, cardiovascular function as well as psychological well-being, compared with exercise training alone. Patients will be randomized 1:1 to an 8 week intervention with exercise training 2 times per week followed by 15 minutes of hot water immersion, or to a control group with exercise training alone. The primary endpoint is changes in the inflammatory marker interleukin (IL-) 6 between groups at 8 weeks. Secondary endpoints include other biomarkers of inflammation, metabolism, effects on cardiovascular function and psychological benefits. Secondary prevention after MI has improved during the last decades but readmissions and death following acute MI remain large health challenges. If HWI in addition to standard cardiac rehabilitation can lower inflammation more than standard therapy alone, and improve metabolic, cardiovascular and psychological status, it could be a cost-effective and safe complementary strategy for secondary prevention after MI, particularly for those with limited exercise capability.
Single center randomized clinical trial. The main aim is to demonstrate the superiority at the clinical level of the ultra fast-track programs versus conventional early postoperative extubation in patients undergoing cardiac surgery.
The goal of this observational study is to learn about the changing over the time of transseptal (TSP) catheterization for catheter ablation of arrhythmias in the left heart. This study aims to investigate if auxiliary tools for TSP catheterization improved the safety and efficacy.
Consequences of stroke are manyfold but all of them are important factors on the long-term outcomes of rehabilitation, becoming an important health problem with requires health strategies with advanced age. High intensity interval training (HIIT) is an efficient training protocol used in cardiac rehabilitation programs, but owing to the inter-individual variability in physiological responses to training associated to cardiovascular diseases, the exercise dose received by each patient should be closely controlled and individualized to ensure the safety and efficiency of the exercise program. The heart rate variability (HRV) is actually being used for this purpose, as it is closely linked to de parasympathetic nervous system activation. In this way, higher scores in HRV are associated with a good cardiovascular adaptation. The objective of this protocol is to determine the effect of HIIT compared with HRV-guided training on cardiorespiratory fitness, heart rate variability, functional parameters, body composition, quality of life, inflammatory markers, cognitive function, and feasibility, safety and adherence in patients after stroke undertaking an 8-week cardiac rehabilitation program. This will be a cluster-randomized controlled protocol in which patients after stroke will be assigned to an HRV-based training group (HRV-G) or a HIIT-based training group (HIIT-G). HIIT-G will train according to a predefined training program. HRV-G training will depend on the patients' daily HRV. The peak oxygen uptake (VO2peak), endothelial and work parameters, the heart rate variability, the functional parameters, the relative weight and body fat distribution, the quality of life, the inflammatory markers, the cognitive function, and the exercise adherence, feasibility and safety will be considered as the outcomes. It is expected that this HRV-guided training protocol will improve functional performance in the patients after stroke, being more safe, feasible and generating more adherence than HIIT, providing a better strategy to optimize the cardiac rehabilitation interventions.
Patient reported outcomes are becoming increasingly recognized as an important metric to determine efficacy of interventions following recovery after cardiac surgery. Quality of Recovery 15 survey is a tool that attempts to measure patients' recovery across several different domains (i.e physical, emotional and social). This tool has been validated extensively in the post operative patient population, but these studies contained only small numbers of cardiac surgery patients. This population faces unique challenges to recovery such as a longer duration of mechanical ventilation, ICU and hospital LOS, delirium, significant pain in the first 24-48 hours and post operative arrhythmias. This study aims to validate the QoR 15 in this population exclusively to determine if it is feasible, valid, reliable and responsive in this unique population.
The purpose of this research is to validate the prototype AI-Flex device. Researchers at Mayo Clinic developed a new a flexible multi-modal bio-sensing device, AI-Flex, with integrated artificial intelligence (AI) capability. Integration of sensing and AI analysis on the same device removes the need for data storage on the cloud for later analysis. The goal of the device is to allow real-time monitoring of patient health and timely intervention based on patient health condition. It is hoped that the proposed flexible device will allow intimate skin contact using ultra-thin (<10 µm) geometry to reduce or eliminate relative movement between the skin and flexible epidermal sensors even during rapid motion of the subject, which would significantly improve the sensor signal quality for AI analysis.
Certain diseases relating to the heart can only be definitively treated with surgery. When untreated, these can lead to heart failure with a lack of supply of oxygen-rich blood to the tissues, leading to damage to other organs. Adults who undergo heart surgery vary greatly in terms of age and relative health. This has significant implications when predicting outcomes in the aftermath of surgery. For example, a 90-year-old man with a variety of comorbidities such as diabetes and high cholesterol who requires a heart valve replacement may have an unfavourable chance of surviving the postoperative period when compared to an 18-year-old woman with no significant medical history undergoing the same procedure. Almost invariably, patients are admitted to an Intensive Care Unit (ICU) following heart surgery. This is done to facilitate close monitoring of the patients' vital organ functions and to also provide organ support if needed. For the heart, this can include the administration of drugs to help a heart pump forcibly, cause blood vessels to contract and increase blood pressure. Patients who have undergone heart surgery have been placed on a mechanical ventilator, following a tube placed in their windpipe. This form of ventilation often continues in ICU for a period of time, depending on the patient's condition. One specific type of ICU level monitoring that occurs in patients who have undergone heart surgery is cardiac output monitoring. This involves a thin tube, called a pulmonary artery catheter, that extends from the skin to the heart, via large blood vessels. Cardiac output monitoring is essential in this patient group to guide organ support and to provide information of how well the heart is functioning. In this observational study, the investigators wish to study patients who have undergone cardiac surgery, are receiving mechanical ventilation and have pulmonary artery catheters inserted. The investigators will collect cardiopulmonary data in these patients and compare these data with values of exhaled and inhaled gases (oxygen and carbon dioxide) over the same time period. This will enable the investigators to investigate the link between cardiopulmonary data and respired gas values. A better understanding of this link between cardiopulmonary function and oxygen/carbon dioxide values will then inform future studies aiming to determine the effect of various interventions in similar patient groups.
Echocardiography is the examination of choice for the study of cardiac pathologies. Interest of echocardiography for other medical specialties has already been demonstrated (intensive care in the case of hemodynamic failure - in intra and extra hospital emergency medicine for the initial assessment of chest pain or dyspnea). The expansion of echocardiography'use has been catalyzed by miniaturization of echographic systems and decrease in their price. Recently, probes directly connected to a tablet or phone have been developed at a limited cost. Therefore, it's possible to consider these ultrasound scanners as the new stethoscope that could be used by any health professional. The last limit to this democratization is the training, especially for non-specialists (non-cardiologists).
