NCT06890169
The goal of this clinical trial is to learn if the use of a care model including teleconsults and the EMPOWER app can induce clinically significant weight loss and metabolic improvements in obese adults with diabetes and metabolic dysfunction-associated steatotic liver disease (MASLD). Researchers will compare this model with the conventional standard of care of physical visit-based weight management program to see if this model is non-inferior to the standard of care for inducing weight loss, and if there is greater patient convenience with telehealth and more frequent self-monitoring, compliance with diet advice and exercise participation compared to standard of care. Participants in the standard arm will attend 4 physical doctor and 4 physical dietician consultations over 26 weeks, where they will be provided with an individualized diet and exercise prescription to induce at least 5% weight loss. Participants in the intervention arm will have the same number of consults over 26 weeks, of which at least 50% will be teleconsults, and will also be provided with an individualized diet and exercise prescription to induce at least 5% weight loss. In addition, they will be taught to use the EMPOWER app to upload weight, blood pressure and glucose, food and exercise records which will be reviewed at the consults. The app also delivers nudges to improve adherence to lifestyle modification.
NCT06254534
This clinical trial aims to compare the effects of lidocaine, dexmedetomidine, esmolol, and magnesium on optic nerve sheath diameter and hemodynamic response to laryngoscopy. The participants will be patients determined to need intubation and general anesthesia for any elective surgery. Each participant will receive either lidocaine, dexmedetomidine, esmolol, magnesium, or none before anesthesia induction, according to randomization. The investigator will measure the optic nerve sheath diameter by ultrasonography before and after intubation. Researchers will compare the difference between optic nerve sheath diameter, systolic blood pressure, and heart rate before and after laryngoscopy and search for the most stable group. The trial aims to determine a general anesthesia induction protocol for patients sensitive to intracranial pressure changes reflected as optic nerve sheath diameter for easy monitoring.

NCT06671171
Wearable health technology, particularly smartwatches, has revolutionized personal health monitoring by enabling continuous, non-invasive tracking of various physiological parameters. The potential applications of these devices in cardiology are extensive, but it is crucial to validate their accuracy against established medical-grade devices. The Apple Watch Series 9 (Apple, USA) exemplifies the capabilities of modern smartwatches, offering a wide range of health tracking features. These include heart rate monitoring, detection of irregular heart rhythms suggestive of atrial fibrillation, electrocardiogram recording, blood oxygen level measurement, and comprehensive mobility metrics (including VO2 max, six-minute walk distance, walking speed, step length, double support time, and walking asymmetry). Many of these parameters are highly relevant for cardiovascular patients, potentially aiding in disease progression monitoring and adverse event prediction. However, there is a lack of comprehensive validation studies for these devices in specific cardiovascular disease populations. This investigator-initiated prospective observational study involving 50-100 participants that aims to validate smartwatchbased assessments using medical-grade devices and techniques. The study will focus on adult patients with congenital heart disease, pulmonary hypertension, heart failure, and coronary artery disease, as well as athletes undergoing cardiovascular assessment. By comparing smartwatch data with established clinical measurements, the investigators seek to determine the reliability and potential clinical utility of these wearable devices in diverse cardiovascular contexts. This research will help bridge the gap between consumer-grade wearable technology and clinical practice in cardiology.
NCT06741436
Though cardiovascular disease (CVD) is the leading cause of mortality in women, traditional epidemiology in this area has focused on later life, when cardiometabolic risk has already exacted a cumulative toll on the vascular system. Recent data from the investigators and others has highlighted pregnancy as a unique, early moment of cardiovascular stress in young women that may "unmask" CVD propensity. It is unclear if PreE simply represents a "failed stress test" or directly contributes to the pathophysiology of future CVD. While mechanistic studies have largely been the purview of model-based studies, endothelial dysfunction has emerged as central to the pathogenesis of both PreE and peripartum cardiac dysfunction. Indeed, biomarkers of endothelial dysfunction and angiogenic imbalance during pregnancy have been shown to remain elevated at least 6 months post-partum. Moreover, peri-partum endothelial dysfunction can persist for years post-delivery and remains a significant risk factor for CVD (even after adjustment for other traditional risk factors). While these findings suggest that PreE-associated endothelial dysfunction and inflammation may contribute to early myocardial dysfunction that presages HF risk decades before its onset, the modifiable epidemiology of PreE-associated LVDD, including potential mechanisms of risk, remains unclear, limited by lack of precision molecular phenotypes accessible in a large number of American women across race. Ultimately, understanding the epidemiology and pathobiology of PreE-associated myocardial dysfunction affords a unique opportunity to identify women at risk with a longer lead-time for risk factor modification to interrupt CVD. The investigators hypothesize that persistent structural-functional myocardial alterations after PreE are linked to pre- and post-gravid cardiometabolic risk factors (SA1), functional and hemodynamic impairment (SA2) and select pathways of vascular and inflammatory stress relevant to HF risk (SA3). Despite extensive study on the role of inflammation/ischemia in PreE, there have been no large studies connecting these phenotypes with early PP functional response and biochemical alterations, a key barrier to designing studies for improving CVD/HF in women. SA1: To identify pregnancy-specific clinical factors related to postpartum HFpEF phenotypes Clinical Implication: Improve identification of women at highest risk for developing post-PreE LV diastolic dysfunction (a harbinger of HFpEF). SA2: To define functional and hemodynamic signatures of early HFpEF due to preeclampsia Clinical Implication: Identify women at highest risk for developing early HFpEF. SA3: To identify shared pathophysiologic mechanistic pathways for PreE-associated HFpEF Clinical Implication: Identify targetable pathways for post-PreE cardiac dysfunction that may prevent/ delay HFpEF development.
NCT06759805
In Norway, more than 11,000 patients undergo percutaneous coronary intervention (PCI) annually. However, a very recent study utilizing registry data show a national average of cardiac rehabilitation (CR) participation of only 14%, despite its proven beneficial effects on readmissions, physical capacity, psychological distress, self-management, and quality of life. CR is strongly recommended in European guidelines. However, uptake is low and is not systematically identifying those in most need of CR. The primary objective of eCardiacRehab is to meet rehabilitation needs of large patient populations regardless of their access to traditional place-based rehabilitation by developing and evaluating the efficacy and cost effectiveness of an interdisciplinary and comprehensive home-based eCardiacRehab programme. eCardiacRehab address patient- and system level challenges in order to increase access to CR. The investigators give particular attention to older patients, women, and those with comorbidities or mental health challenges. Aspects related to continuity of care between specialist and primary care services, health literacy, adherence to treatment, cost effectiveness and ethics are investigated. The investigators will 1) continue to develop the programme with patients, general practitioners, healthcare experts from both specialist and primary care services, and technology developers, 2) develop treatment modules, 3) establish information and communication infrastructure, 4) evaluate the process and efficacy of treatment modules, 5) ensure knowledge development and transfer of competence to the municipalities, and 6) contribute to fulfil the innovation potential for health service and industry partners. eCardiacRehab has the potential to improve interaction and collaboration between primary and secondary care, modernise and digitalise work processes, and develop more coherent and tailored patient pathways. The vision of the home-based eCardiacRehab is to make CR available to all.
NCT03928002
Congenital heart disease is the most common congenital anomaly. The life expectancy of children with congenital heart disease has increased considerably in recent years. Nevertheless, the evolution of these patients is marked by an increased risk of complications. Arrhythmias, heart failure, pulmonary arterial hypertension (PAH) and endocarditis may be promoted by the absence or delay of management in childhood, by residual lesions or post-operative cardiac scars and by the presence of prosthetic materials. PAH is a common complication of congenital heart disease, especially in non-operated shunts. PAH corresponds to an increase in pulmonary vascular resistance and mean pulmonary arterial pressure that becomes greater than 25mmHg at rest, leading to right ventricular failure and ultimately to the patient's death. Eisenmenger's syndrome corresponds to a non-reversible pulmonary arterial hypertension with a left-right shunt initially left open, then right-left secondary to the increase in pulmonary vascular resistance, leading to cyanosis, polycythemia and multivisceral involvement. It is the most advanced form of PAH with congenital heart disease. PAH will be suspected during echocardiographic follow-up of any patient with congenital heart disease, on the analysis of the velocity of tricuspid and/or pulmonary regurgitation flow. Echocardiography allows the monitoring of the VD (right ventricle) function, which is the major prognostic element in PAH. Cardiac catheterization is systematically recommended and remains the gold standard to confirm the diagnosis of PAH, establish its pathophysiology and prognosis but also for the follow-up under medical treatment of these patients in tertiary centres every 6 months. Although this tool is the gold standard, rigorously performed, it remains an invasive examination often poorly experienced by patients. 4D Flow MRI is a promising imaging that allows the acquisition of anatomical, volume, right ventricular remodeling and intracardiac flow information in a single step with 2D (only 8 minutes extra), in free breathing and totally autonomous mode. Thus, at the same time as the realization of a 2D MRI, essential for the diagnosis and follow-up of PAH, with an additional 8 minutes for 4D flow, the investigators could have additional fundamental information on pulmonary cardiac output but also prognostic markers of right ventricular dysfunction turning dramatic in pulmonary vascular disease.

Functional and cognitive rehabilitation: Attending weekly in-person sessions for 8 weeks, including supervised physical and cognitive exercises. 2. Informational support: Receiving weekly evidence-based educational messages for 8 weeks. Participants will undergo assessments at baseline, post-intervention, and six months later, including a six-minute walk test, handgrip strength measurement, and questionnaires on disability, anxiety, depression, fatigue, dyspnea, cognitive function, and quality of life.
NCT04508582
Preeclampsia is a multi-system vascular disease which affects 2-5% of pregnancies. It is also a risk factor for the development of cardiovascular disease later in life and a number of functional and structural cardiac changes have been found in this population of patients. In mouse models disruption of a group of immune cells, neutrophils, has led to alteration of the placenta and offspring consistent with those seen in preeclampsia. These mice also have an abnormal cardiac function and structure (Nadkarni et al 2016). The investigators hypothesis that this may also occur in humans. This study aims to intimately link the maternal immunological and vascular components of cardiac dysfunction in women preeclampsia. The investigators hypothesise that in preeclampsia activated neutrophils may affect maternal immune system thus leading to myocardial injury and altered cardiac function. The study intends to identify the mechanisms by which the maternal immune system (focusing on neutrophil and T-cell subsets) affects cardiac function in women with preeclampsia. Specific aims to be addressed are: Aim 1: To correlate specific neutrophil phenotype(s) and function to cardiac function in women with preeclampsia during pregnancy Aim 2: To test whether specific activated neutrophil phenotype persists postpartum and whether this neutrophil phenotype correlates with cardiac function in women with preeclampsia postpartum The study population will comprise of 3 groups: 1. Normotensive pregnant (\~33 patients) 2. Pregnancy-induced hypertension (PIH; New-onset hypertension after 20 weeks without proteinuria; \~33 patients) 3. Preeclampsia (\~34 patients) Cardiac function will be evaluated using cardiovascular magnetic resonance, echocardiography and cardiac markers in the blood. The participants immune system will be assessed from blood samples looking at the immune cells, hormone levels and inflammatory and non-inflammatory mediators. The secondary research objective is to investigate whether changes in the immune system and cardiac function in participants is persistent after delivery. Therefore participants will have scans and blood tests both antenatally and at 3 months postnatally. By identifying key changes in immune cell type and function with cardiac abnormalities in women with preeclampsia, data obtained from this study could provide novel insight into how the maternal immune system influences cardiac changes in normal and preeclamptic pregnancies. Identifying such links could pave the way for future therapeutic targets.
