Standard coagulation tests and ROTEM measurements will be collected and analyzed in relation to clinical outcomes.
Myocarditis Acute
This is a phase III, multi-center international, single blind randomized controlled trial to test the efficacy of pulsed intravenous (IV) methylprednisolone versus standard therapy on top of maximal support in patients with Acute myocarditis (AM).
Ischemic Stroke · Dysphagia
Ischemic stroke is a common clinical disease, often accompanied by dysphagia. At present, clinical treatment for patients with dysphagia after ischemic stroke is limited. The emergence of NGF has surprised the field of neurorehabilitation, but the clinical effect is not satisfactory. The main problem is that NGF is a macromolecular material with a molecular weight of 13.4 KD, which is difficult to penetrate the blood brain barrier. A large number of previous studies in our team have found that electroacupuncture with specific stimulation mode can open the blood brain barrier and induce NGF into the brain. Therefore, the purpose of this study is to investigate the effect of specific mode electroacupuncture stimulation combined with NGF treatment on patients with dysphagia after ischemic stroke and to explore the mechanism of this combination therapy to improve brain function, which creates a new method and theoretical basis for nerve rehabilitation of integrated traditional Chinese and Western medicine.
Cerebral Aneurysms · Intracranial Aneurysms · Coil Embolization
The goal of this clinical trial is to evaluate whether non-invasive continuous blood pressure monitoring (NVBP) using the ClearSight system can safely serve as an alternative to radial arterial catheterization for invasive arterial blood pressure monitoring (IABP) in patients undergoing coil embolization for unruptured intracranial aneurysms. The main questions it aims to answer are: * Does NVBP monitoring detect intraoperative hypotension and hypertension events with similar reliability compared to IABP? * Does NVBP monitoring reduce the need for invasive arterial catheterization without compromising patient safety or clinical outcomes? Researchers will compare patients assigned to NVBP monitoring with those receiving conventional IABP monitoring. Participants will: * Be randomly assigned to NVBP monitoring or standard IABP monitoring during coil embolization. * Receive continuous monitoring of cerebral oxygenation with near-infrared spectroscopy (rSO₂). * Undergo standard anesthesia induction, maintenance, and postoperative intensive care protocols. * Have their intraoperative hemodynamic events, vasopressor use, and postoperative outcomes recorded up to 30 days after the procedure.
Sleep Disorder (Disorder) · Cardio Vascular Disease
The goal of this observational study is to validate a simplified questionnaire, adapted for routine clinical use, to quickly detect sleep disorders in patient during a cardiology consultation. Two questionnaires were developed for this project. The first is patient-oriented: a prospective, multicentre, national observational registry based on a patient questionnaire designed to quickly detect sleep disorders during a cardiology consultation. The second is aimed at treating cardiologists: this is a simple impact survey designed to assess changes in the practices of cardiologists who participated in CARDIOSOM.
Hypertension
The goal of this clinical trial is to determine if the medication eplerenone yields greater improvements in coronary microvascular function than chlorthalidone in women who experienced preeclampsia during pregnancy and subsequently developed chronic hypertension. The main Aims are: * To test the hypothesis that, in women with prior preeclampsia, current chronic hypertension, and concentric LV remodeling, eplerenone improves coronary microvascular function vs. chlorthalidone. * To test the hypothesis that, in women with prior preeclampsia, current chronic hypertension, and concentric LV remodeling, eplerenone improves cardiac structure and function vs. chlorthalidone. Participants will: * First receive pre-treatment with Amlodipine for 12 weeks prior to beginning the study medication. * Start study treatment which involves daily self-administration of two oral capsules (eplerenone + potassium placebo or chlorthalidone + potassium), each taken once a day, for a total of 336 doses over 48 weeks. * Attend study visits at weeks 2, 12, 24, 36, and 48. These visits will involve collecting information, measuring blood pressure, and gathering blood and urine samples. Echocardiography (cardiac ultrasound), eye exam, and cardiac PET/CT scan will be performed during the baseline and week 48 visits.

The main outcome is detection of vision impairment and secondary outcome is detection of conditions needing ophthalmologic follow-up but not presenting vision impairment at present time.
Stroke · Pain · Exercise Induced Hypoalgesia
Exercise has shown multiple beneficial effects in both healthy and post-stroke populations. One of these is the acute reduction in sensitivity to painful stimuli, called exercise-induced hypoalgesia (EIH). This phenomenon has been studied since 1979 and has shown improvements in pain thresholds with both aerobic and resistance training in healthy, pain-free populations and different chronic pain conditions. Although there has been extensive research on EIH in healthy populations and those with chronic musculoskeletal pain, surprisingly little attention has been given to individuals with neurological pathologies. Chronic pain is found in more than 50% of patients after stroke, and 70% of affected individuals experience pain on daily activities. Reported prevalences of post-stroke pain (PSP) between different studies, but there is a general consensus that it is an underreported phenomenon. Patients with pain experience greater cognitive and functional decline, fatigue, depression and lower quality of life. Multiple factors contribute to PSP, and various approaches exist to treat all the variables influencing it. This study aims to compare the effects of exercise on pain perception in healthy individuals and stroke patients without pain, using the same cardiovascular training protocol, to better understand the mechanisms of EIH and its maintenance after stroke, ultimately aiming to improve the treatment of people with stroke.

Sickle Cell Disease · Cerebral Stroke
The purpose of the study protocol is to identify imaging biomarkers for brain tissue under high metabolic stress at risk for permanent injury. We will measure oxygen extraction fraction (OEF) and cerebrovascular reactivity (CVR) in participants with and without perturbations in cerebral oxygen delivery over time to determine each parameter's role in clinical and radiologic neurologic outcomes. Measuring OEF can be done with specialized MRI sequences. Measuring CVR requires a vasoactive response, such as carbon dioxide. In order to deliver carbon dioxide evenly and as safely as possible, we will use RespirACT, an MRI-compatible device, to prevent over-breathing carbon dioxide and allow rapid steady-state physiology to minimize total scan time. We will also use a high density diffuse optical tomography (HD-DOT) cap to assess the measurement of OEF and CVR. This study will investigate both regional OEF and CVR simultaneously to understand each marker's unique developmental trajectory and contribution to stroke risk in children. This work will expand insights into mechanisms of stroke in children and assess the feasibility of the HD-DOT cap for obtaining these insights by comparing a cohort of optical CVR and a cohort of MRI CVR. In addition to the MRI and/or HD-DOT cap with RespirAct, participants may also have their vitals measured, complete cognitive testing, and complete a blood draw with a study visit. Participants may be followed for up to three years and may complete both an MRI scan and an HD-DOT scan within 1 week-12 months of each other. Participants may be invited back to repeat MRI and/or HD-DOT scans 1-2 times over the next three years.

Congenital Heart Disease
To assess the accuracy and clinical utility of a novel non-invasive ECGI mapping system in identifying arrhythmogenic regions of interest in patients with congenital heart disease.
Left Heart Failure
Eccentric muscle work is defined as lengthening of a muscle while applying force. It was shown that with eccentric work, muscles are able to perform four times as much power compared to usual concentric work, which results in huge training gain with a highly decreased oxygen demand and thus lower cardiovascular load. Pulmonary hypertension (PH) is a chronic condition associated with significant reduced exercise capacity and increased morbidity and mortality, resulting in reduced quality of life. Physical training has been shown to be beneficial in PH, even in severely limited patients. However, due to cardiopulmonary constraints in PH, training intensities may be very low, so that many patients are physically almost unable to perform exercise on a high enough level to maintain muscle mass. A low body muscle not only feeds the vicious cycle of decreasing exercise capacity, but also has many deleterious metabolic and immunological consequences which further increase disability and decrease quality of life in PH. Thus, eccentric training, which allows to gain muscle mass with a low stress to the cardiopulmonary unit may to be highly beneficial for patients with PH and allied cardiopulmonary disease, such as chronic obstructive pulmonary disease (COPD) and heart failure. Therefore, the objective of the trial is, to compare differences in oxygen uptake (peak VO2 \[l/min\]) and other physiological measures during similar cardiopulmonary exercise test protocols of eccentric- vs. concentric cycling in PH- patients and comparators with or without other cardiopulmonary diseases.
