360 Clinical Trials for Various Conditions
In this study, the hypothesis being explored is that VO2Max and other CPET parameters can be accurately estimated from biosignals (namely, motion from accelerometers and cardiopulmonary variables from EKG) collected during activities of daily living using wearable biosensors worn by study participants. This study will aim to collect development and validation data for a machine learning algorithm and to evaluate the performance of the algorithm. A total of 300 participants will be enrolled including: (Normal) 200 participants, self-reported healthy male and female participants aged 18 to 80 and (Standard of Care) 100 participants
The purpose of this research study is to test the accuracy of the Dexcom continuous glucose monitoring device during the cardiothoracic surgical procedure and recovery period in the Cardiac Intensive Care Unit. Readings from the device will be compared with the standard of care blood glucose levels that are obtained during your surgery and postoperatively.
Short-term and long-term consequences of severe cardiac and/or lung dysfunction can be increased use of sedation, prolonged bedrest and immobility causing severe loss of muscle mass which could be a risk for muscle weakness, osteoporosis, and lowered endurance. The goal of this study is to show how a structured rehabilitation program can exhibit better short-term and long-term outcomes on patients who are treated with extracorporeal membrane oxygenation (ECMO).
The COR-INSIGHT trial aims to evaluate the effectiveness of Peerbridge COR advanced ambulatory ECG wearables (COR 1.0 and COR 2.0) in accurately and non-invasively detecting cardiovascular and cardiopulmonary conditions using AI-based software (CardioMIND and CardioQSync). The study devices offer non-invasive, multiplexed, AI-enabled direct-from-ECG detection as a novel alternative to traditional diagnostic methods, including imaging, hemodynamic monitoring systems, catheter-based devices, and biochemical assays. Continuous COR ECG data collected in hospital, outpatient clinic, or home settings will be analyzed to evaluate the predictive accuracy, sensitivity, specificity, and performance of these devices in differentiating between screen-positive and screen-negative subjects. The panel of screened indications encompasses a broad spectrum of clinically relevant cardiovascular, cardiopulmonary, and sleep-related diagnostic parameters, which are critical for advanced patient assessment and management. In the cardiovascular domain, the protocol emphasizes the detection and classification of heart failure, assessment of ejection fraction severity, and identification of myocardial infarction, including pathological Q-waves and STEMI. It further addresses diagnostic markers for arrhythmogenic conditions such as QT interval prolongation, T-wave alternans, and ventricular tachycardia, as well as insights into ischemia, atrial enlargement, ventricular activation time, and heart rate turbulence. Additional parameters, such as heart rate variability, pacing efficacy, electrolyte imbalances, and structural abnormalities, including left ventricular hypertrophy, contribute to comprehensive cardiovascular risk stratification. In the non-invasive cardiopulmonary context, the protocol incorporates metrics like respiratory sinus arrhythmia, cardiac output, stroke volume, and stroke volume variability, providing critical insights into hemodynamic and autonomic function. The inclusion of direct-from-ECG metrics for sleep-related disorders, such as the apnea-hypopnea index, respiratory disturbance index, and oxygen saturation variability, underscores the protocol's utility in addressing the intersection of cardiopulmonary and sleep medicine. This multifaceted approach establishes a robust framework for precision diagnostics and holistic patient management. The COR 1.0 and COR 2.0 wearables provide multi-lead ECG recordings, with COR 2.0 offering extended capabilities for cardiopulmonary metrics and longer battery life (up to 14 days). COR 2.0 supports tri-modal operations: (i) Extended Holter Mode: Outputs Leads II and III, mirroring the functionality of COR 1.0 for broader ECG monitoring applications. (ii) Cardiopulmonary Mode: Adds real-time recording of Lead I, V2, respiratory impedance, and triaxial accelerometer outputs, providing advanced cardiopulmonary insights. (iii) Real-Time Streaming Mode: Streams data directly to mobile devices or computers via Bluetooth Low Energy (BLE), enabling real-time waveform rendering and analysis. The COR 2.0 units are experimental and not yet FDA-cleared. Primary endpoints include sensitivity (true positive rate) \> 80%, specificity (true negative rate) \> 90%, and statistical agreement with reference devices for cardiovascular, cardiopulmonary, and sleep metrics. Secondary endpoints focus on predictive values (PPV and NPV) and overall diagnostic performance. The study employs eight distinct sub-protocols (A through H) to address a variety of cardiovascular, cardiopulmonary, and sleep-related diagnostic goals. These sub-protocols are tailored to specific clinical endpoints, varying in duration (30 minutes to 14 days) and type of data collection. Up to 15,000 participants will be enrolled across multiple sub-protocols. Screening ensures eligibility, and subjects must provide informed consent before participation. Dropouts and non-compliant subjects will be excluded from final analyses.
Cardiac surgery is a procedure that is commonly performed worldwide. Despite these technological advances, cardiac surgery remains a high-risk surgery. Among post-operative complications, acute kidney injury, respiratory failure, myocardial infarction, and stroke as well as cognitive dysfunction are significant causes of mortality in patients undergoing and following cardiac surgery. Inhaled nitric oxide (NO) therapy as a selective pulmonary vasodilator in cardiac surgery has been one of the most significant pharmacological advances in managing pulmonary hemodynamics and life threatening right ventricular dysfunction and failure. In addition, newer applications show greater promise of inhaled NO as a therapy in the area of cardiac surgery associated acute kidney injury and ischemia reperfusion. However, this remarkable expectation to inhaled NO has experienced a roller-coaster ride with high hopes and nearly universal demonstration of physiological benefits but disappointing translation of these benefits to harder clinical outcomes, like mortality. Most of our understanding on the iNO field in cardiac surgery stems from small observational or single center randomized trials, which failed to ascertain strong evidence base. As a consequence, there are only week clinical practice guidelines on the field and only European expert opinion for the use of iNO in routine and more specialized cardiac surgery. There is need for a large multicenter randomized controlled study to confirm the administration of iNO as an effective weapon for the battle against life threatening complication in high risk cardiac surgical patients. In a previous meta analysis with 27 studies included, we demonstrated that inhaled nitric oxide (NO) could reduce the duration of mechanical ventilation and reducing biomarkers of organ injury and clinical signs of organ dysfunction in cardiac surgery under cardiopulmonary bypass (CPB) , but had no significance in the ICU stay, hospital stay, and mortality. This may be attributed to the small sample size of the most included studies (of the 27 studies included, 20 studies with sample size less than 100) and heterogeneity in timing, dosage and duration of iNO administration. Well-designed, large-scale, multicenter clinical trials are needed to further explore the effect of iNO in improving postoperative prognosis in cardiovascular surgical patients. We are planning a large multicenter controlled randomized trial to demonstrate that inhaled nitric oxide can reduce composite outcome of death and Major Adverse Events (MAEs), including need for intensive supports due to heart failure, low cardiac output sydrome, or renal failure, respiratory failure, etc., and myocardial infarction, stroke, and sepsis at 30 days after surgery from 20% to 16% in patient undergoing cardiac surgery with cardiopulmonary bypass. If the hypothesis had been proved and validated, the results of this study can provide strong evidence for guidelines to facilitate the routine use of iNO in all cardiopulmonary bypass assisted cardiac procedures with 31,800 postoperative outcomes improved per year in US and in China.
The overarching goal of this study is to determine if baricitinib, as compared to placebo, will improve neurocognitive function, along with measures of physical function, quality of life, post-exertional malaise, effect of breathlessness on daily activities, post-COVID-19 symptom burden, and biomarkers of inflammation and viral measures, in participants with Long COVID.
The purpose of this study is to compare the difference in the ability to detect hemodynamic abnormalities between invasive hemodynamic assessments performed at rest versus exercise, to assess the correlation between invasive and noninvasive (Doppler-derived) rest-exercise hemodynamic indices and to compare the association between indices of disease severity and hemodynamic abnormalities identified at rest versus exercise.

The goal of this clinical trial is to learn whether physicians can associate evidence of myocardial injury after surgery with findings obtained from submaximal cardiopulmonary exercise testing. The main questions are: Is detection of postoperative myocardial injury with submaximal cardiopulmonary exercise testing superior to using usual care? And which submaximal cardiopulmonary exercise testing measure is better? Participants will undergo evaluation with a short submaximal cardiopulmonary exercise test, then undergo surgery. Myocardial injury will be measured on postoperative days 0, 1, 2, and 3 (during and up to 3 days after surgery). These results will analyzed by comparing it to findings from the submaximal cardiopulmonary exercise test. If there is a relationship, this will help anesthesiologists and surgeons assign certain treatments that may reduce the risk of developing myocardial injury after surgery.
SURVIVORS Study participants are being asked to take part in this research study called HODNIRS because the participant is a survivor of Hodgkin Lymphoma (HL) treated with chest radiation and bleomycin at St. Jude Children's Research Hospital.

The value of clinical cardiopulmonary exercise testing (CPET) within healthcare settings has been established in the last decade. CPET methods remain highly relevant in the COVID-19 endemic phase and should be used to assess those recovering from COVID-19 (SARS-CoV-2) infection. This diagnostic tool could play an integral role in disease prognostication and evaluate the integrative response to incremental exercise. Date from such assessments can enable practitioners to characterise cardio-respiratory fitness and identify reasons for physical impairment or abnormal cardio-respiratory function. More than 50% of patients admitted to hospital will experience cardiorespiratory issues and significant morbidity during their recovery and will require significant rehabilitative support. In this context, measurements obtained from an assessment of cardio-respiratory responses to physiological stress could provide insight regarding the integrity of the pulmonary-vascular interface and characterisation of any impairment or abnormal cardio-respiratory function. Current approaches to rehabilitation are being developed on existing knowledge from Severe Acute Respiratory Syndrome (SARS) and Acute Respiratory Distress Syndrome (ARDS) related illness. These provide important insight but do not provide insight into the novel challenges provided by COVID-19.

Aerosol Generating Medical Procedures (AGMP) are procedures that have the potential to create tiny particles suspended in the air. These particles can contain germs such as viruses. The Coronavirus Disease 2019 (COVID-19) pandemic was caused by the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Patients infected with SARS-CoV-2 experience unusually high rates of critical illness that needs advanced airway management and intensive care unit admission. Bag-valve-mask (BVM) ventilation, endotracheal Intubation (ETI) and chest compressions are sometimes required for critically ill COVID-19 patients, and may contribute to a high risk of infection amongst Health Care Workers (HCW). To lessen HCW risk during high-risk procedures, a device called an aerosol box has been developed to place over the head of the patient, shielding the provider's face from virus droplets suspended in the air. The purpose of this research study is to better understand how particles disperse during AGMPs, more specifically during the provision of cardiopulmonary resuscitation (CPR). The project team hopes what is learned from the project can help inform infection control measures. This could help make changes to the clinical environment and make it safer for HCW's. The investigators intend to explore how an aerosol box performs in reducing contamination of HCW's who perform critical airway interventions during resuscitation events.
The goal of this observational study is to compare the effects of air pollution exposure and nutrition between neighborhoods with high and low social vulnerability scores. The main questions this study aims to answer are: * Does living in a neighborhood with high or low vulnerability influence the response of the heart, lungs, and immune system to air pollution. * Does nutritional status alter the association between air pollution exposure and changes in the heart, lungs, and immune system. Participants (age 25-70 years) that live in neighborhoods ranked high or low on the Social Vulnerability Index (SVI) will take part in 3 visits. Each visit involves the following: * Measurements of heart activity, lung function, and blood to measure changes that may be caused by air pollution. * Questionnaires about the types of food eaten and activities that may modify exposure to air pollution. * Estimation of air pollution exposure using a study iPhone. Participants will carry a study iPhone with them for 24 hours at each visit. The study iPhone runs an application (app) that estimates the amount of air pollution each participant is exposed to. * Wearing silicone wristbands for a week before each study visit. Silicone wristbands absorb air pollutants and are later measured see the types and amounts of chemicals participants are exposed to.
