Utilization of additional wearable data to improve clinical outcome

Multivariate Approach to the Numerical Assessment of Cortical - Autonomic - VAscular Dynamic Interplay

MANCAVA sets out fundamental methodologies for characterizing human fundamental physiological system interactions at a whole-body level, particularly focusing on the interplay among cortical brain activity, autonomic function, and cerebrovascular autoregulatory mechanisms. By investigating the complex, time-varying mechanisms underlying the multisystem dynamic interactions, novel methods linking various brain areas and reflex functions to target organs and districts such as heart and circulatory system are proposed with the clinical aim linked to the emerging topic of depression. In this scenario, proper new mathematical tools will allow a significant leap from the current state of the art, paving the way towards a new understanding of leading comorbid contributors to global diseases such as cardiac and cerebrovascular morbidity in mood disorders. In turn, this will provide an integration among physiological and psychological dimensions for a more holistic view on depression. Researchers, professionals, and patients will all benefit from a comprehensive assessment of brain-mind-body interplay, leading to the new extended definition of default mode/mood network, neurovascular-evoked responses to autonomic stimuli, brain-autonomic consequences of emotional responses, and physiological substrates of depressive states.

Cardiac Clearance vs G60 Hip Frailty Index

BoStOn SCientific Rhythm MAnagemenT REgiStry (SOCRATES)

SOCRATES is part of Boston Scientific's (BSC) Post-market surveillance system. The implementation of such systems is mandatory per local regulations such as the Regulation '(EU) 2017/745 of the European Parliament and of the Council of 5 April 2017 on medical devices' or short Medical Device Regulation (MDR). The SOCRATES design is therefore based on the BSC's commitment as well as external regulatory requirements to proactively and systematically gather, record and analyze relevant data on the quality, performance and safety of devices throughout their entire lifetime.

Factor VIII Inhibitor Bypass Activity (FEIBA) Versus Fresh Frozen Plasma As First Line Therapy For Bleeding After Cardiac Surgery

Coagulopathic-induced bleeding after cardiopulmonary bypass in cardiac surgery patients is common and is associated with adverse outcomes in cardiac surgery. The hypothesis of the study is that FEIBA will be a more effective treatment than standard of care (FFP) in cardiac surgery patients who have coagulopathic-induced bleeding. This study is being conducted to determine the efficacy of FEIBA versus FFP as first line therapy in correcting coagulopathic induced microvascular bleeding in cardiac surgery patients.

Ask Questions About Clinical Trials

The overall goal of this study is to assess the implementation of the Ask Questions about Clinical Trials (ASQ-CT) brochure, a patient-focused communication tool previously demonstrated to improve patient-provider communication about clinical trials. Participants will be given the ASQ-CT brochure at Time 1 (baseline) and participants will complete a questionnaire at three timepoints, baseline (Time 1), Pre-Research Visit (Time 2), and Post-Research Visit (Time 3).

Cardiovascular Structure and Function in the Mucopolysaccharidoses

This study's investigators previously demonstrated the potential utility of non-invasive carotid ultrasonography to calculate carotid intima media thickness (cIMT) and stiffness (as measured by the three parameters, carotid cross-sectional distensibility \[cCSD\], carotid cross-sectional compliance \[cCSC\], and carotid incremental elastic modulus \[cIEM\]) in people with mucopolysaccharidoses (MPS). Investigators also studied arterial gene expression in animal models of MPS, and identified upregulation of a number of markers potentially tied to atherosclerosis and inflammation. These include the atherosclerotic marker known as Clusterin (CLU), Cathepsin S, Elastin, and the inflammatory cytokines interleukin 1-α, interleukin 1-β, interleukin 2, and interleukin 6. Other studies have identified elevation in circulating tumor necrosis factor-α correlating with pain and physical disability in certain mucopolysaccharidoses. Since these studies are cross sectional, and not longitudinal, this study aims to annually measure these previously studied biomarkers (carotid measurements, circulating cytokines, cathepsin S, elastin, and CLU) in a large cohort of MPS patients. This study is a 3-year, prospective, anonymized, longitudinal assessment of cardiovascular structure, function, and circulating biomarkers in patients with mucopolysaccharidoses.

One-year Patency Comparison Between Radial Artery and No-touch Saphenous Vein Grafts in Women Undergoing Isolated CABG

The use of a graft from the left internal thoracic artery to the left anterior descending artery has become the gold standard for the indication of coronary artery bypass grafting. However, choosing a graft for the second-best coronary artery, focusing on long-term patency, is still a challenge. The saphenous vein using the "no-touch" technique is an alternative to a radial artery graft, but there is little evidence, especially in women. This randomized clinical study aims to compare the patency of these grafts in the second-best coronary artery in women undergoing coronary artery bypass grafting.

The Clinical Value of Deep Learning-Based Reconstruction Techniques in Cardiac MRI Scanning

By enrolling patients who underwent cardiac MR(Magnetic Resonance) examinations at our center and using randomized allocation, the patients were divided into a study group and a control group. The study group underwent scanning using AI-based(Artificial Intelligence-based) cardiac MRI(Magnetic Resonance Imaging) sequences, while the control group was scanned using non-AI cardiac MRI sequences

Cardiometabolic Disease Risk Factors in Cameroon

Cardiometabolic diseases (CMDs) are a major public health concern in sub-Saharan Africa, including Cameroon. Studies have shown a significant increase in the prevalence of hypertension, diabetes, and obesity in recent years. However, access to timely diagnosis and treatment remains limited, particularly in rural areas. Community-based screening programs have been shown to be effective in identifying individuals with undiagnosed CMD risk factors and promoting early intervention. By leveraging the strengths of community-based approaches, the URBACAM-D study aims to address the growing burden of CMDs in urban Cameroon.

Effect of Colchicine on Perioperative Anti-inflammatory Organ Injury in Cardiac Surgery

All patients will be completed collection of demographic data, clinical data, and be observed for inflammatory organ damage, oxygenation index or SpO2/ FIO2, WBC, NEU, interleukin-1β, interleukin-6, interleukin-8 (IL-1β/6/8), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), procalcitonin (PCT), myoglobin (Myo), creatine kinase-MB (CK-MB), high-sensitivity cardiac troponin T (hs-cTnT), neutrophil elastase (NE), myeloperoxidase (MPO), APACHE II score, alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin, Murray lung injury score, serum creatinine, eGFR, mechanical ventilation time, ICU length of stay, drug-related gastrointestinal reactions, and 30-day and 90-day all-cause mortality, among other indicators.

Opportunistic PK/PD Trial in Critically Ill Children (OPTIC)

OPTIC is a prospective, open-label, non-randomized study of multiple medications administered to approximately 2000 children in the pediatric cardiac intensive care unit (PCICU) per routine clinical car by their treating provider. The purpose of this study is to characterize the PK of drugs routinely administered to children per standard of care using opportunistic and scavenged samples. The prescribing of drugs to children will not be part of this protocol. After the child/adult (\<21 years of age) is consented/enrolled, demographic and clinical data will be extracted from the EHR. Biospecimen information (including date and time of sample collection) will be collected. Data analysis will be conducted on all participants with at least 2 evaluable samples. The protocol represents minimal risk to the children/adults who provide body fluid for this study, including potential loss of confidentiality (samples will be assigned a unique accession number) and risks associated with blood draws. Adverse Events (AEs)/Serious Adverse Events (SAEs) caused by the study specimen collections will be monitored and recorded in the Electronic Data Capture (EDC) system.

Evaluation of Low Dose Colchicine and Ticagrelor in Prevention of Ischemic Stroke in Patients With Stroke Due to Atherosclerosis

REDUCING INFLAMMATION IN ISCHEMIC STROKE WITH COLCHICINE, AND TICAGRELOR IN HIGH-RISK PATIENTS-EXTENDED TREATMENT IN ISCHEMIC STROKE.

Quality of Cardiopulmonary Resuscitation Pre- and Intra Hospital

The survival after intrahospital cardiac arrest has been reported to 15%. In Norway this varies between 16 and 23%.). Many factors are associated with survival after cardiac arrest, both intra- and prehospital. Recent studies have not included information about individual patient factors and the outcome after cardiopulmonary resuscitation (CPR). In the current hospital, we are able to record patient specific information related to a cardiac arrest/CPR situation, and thereby be able to assess patient-related factors associated with both detection, treatment and outcome of CPR.

Development of an Artificial Intelligence Algorithm to Detect Pathological Repolarization Disorders on the ECG and the Risk of Ventricular Arrhythmias

Torsades de Pointes (TdP) are potentially fatal ventricular arrhythmias that are promoted by prolonged ventricular repolarization (Long QT, LQT). The different forms of LQT result from inhibition of cardiac potassium currents (IKr and IKs) or activation of a late sodium current (INaL). These alterations may be either congenital (3 types: cLQT-1: IKs, cLQT-2: IKr, cLQT-3: INaL) or drug-induced (diLQT, via inhibition of IKr). More than 100 medications have received marketing authorization despite a known risk of TdP, due to a favorable benefit-risk ratio (e.g., hydroxychloroquine). QTc, which represents the duration of ventricular repolarization (in milliseconds) - defined as the time from the beginning of the QRS complex to the end of the T wave, corrected for heart rate - is prolonged in all forms of LQT. Specific T-wave abnormalities, depending on the altered ion currents, have been described and can help differentiate the various types of congenital or drug-induced LQT. However, screening for LQT and TdP risk, both at the individual and population levels, currently relies mainly on isolated QTc evaluation and genetic testing, which often takes considerable time to return. Thus, limiting ECG analysis to QTc measurement alone offers low predictive value, as the ECG contains a wealth of additional information beyond a single interval. The investigator recently demonstrated that artificial intelligence (AI)-based ECG analysis using deep-learning convolutional neural networks can detect more discriminative features of the ECG for predicting the type of LQT and the risk of TdP, going beyond QTc alone. Using these techniques, the investigator developed a model with probabilistic modules capable of: predicting TdP risk, identifying LQT subtypes (scores ranging from 0 to 100%), and quantitatively measuring ECG parameters such as QTc, heart rate, PR, and QRS duration. The objective of this project is to prospectively validate our model in real-world conditions across various departments within AP-HP, for: Automatic measurement of QTc, and Identification and classification of LQT types and TdP risk.

External Validation of Artificial Intelligence-enabled Electrocardiography (AI-ECG) for the Detection of Left Ventricular Dysfunction (LVD)

This is a multi-center, retrospective study evaluating the performance of an artificial intelligence-enabled electrocardiography (AI-ECG) algorithm in detecting reduced left ventricular ejection fraction (LVEF ≤ 40%). All included patients from participating hospitals must have undergone a digital 12-lead electrocardiogram (ECG) and an echocardiogram with assessment of LVEF within seven days. The AI-ECG algorithm will be applied to evaluate its diagnostic performance, which will be further assessed across subgroups stratified by demographic characteristics and clinical factors.
