Filter by:The study was a multicenter, two-arm, parallel, open label, prospective study intended for to compare effect of offline community hospital intervention on adherence to drugs and risk factors control in patients with stable coronary artery disease compared with tertiary A-level hospital WeChat-based intervention.
The study was a multicenter, two-arm, parallel, open-label, prospective clinical trial that evaluated a remote intervention with 1 year of follow-up.
Infants with congenital heart disease (CHD) are usually born with a normal weight but develop malnutrition over time, and about 20-50% of these children are usually malnourished. Malnutrition in these patients is multifactorial. To compensate for the increased need for infants and children with CHD, an increase in their caloric intake has been suggested. However, these patients may not be able to receive enough to meet the increased needs and catch-up growth. One of the suggested solutions in these patients to compensate for inadequate food intake is to increase the caloric density of milk or formula. For this purpose, the use of special formulas with higher calorie density or enrichment of normal formula or breast milk using special enrichment formula could be suggested. In the present study, the effect of increasing calorie intake by increasing the concentration of normal formula in comparison with formula with standard concentration on weight gain and other anthropometric indices of CHD patients with malnutrition will be compared.
Acute coronary syndrome (ACS) and sudden cardiac death can be the first manifestation of coronary artery disease and are the leading cause of death in the majority of the world's population. The main pathophysiology of ACS is well-known and fibrous cap thickness, presence of a lipid core, and the degree of inflammation have been proposed as the key determinants of plaque vulnerability. Previous studies using virtual histology intravascular ultrasound or optical coherence tomography showed that clinical application of this concept improved risk prediction of ACS. However, these approaches have not been widely adopted in daily practice due to relatively low positive predictive values, low prevalence of high-risk plaques and the invasive nature of diagnostic modalities. Non-invasive imaging studies with coronary computed tomography angiography (CCTA) also showed the clinical value of CCTA-derived high risk plaque characteristics (HRPC). In addition, the recent progress in CCTA and computational fluid dynamics (CFD) technologies enables simultaneous assessment of anatomical lesion severity, presence of HRPC and quantification of hemodynamic forces acting on plaques in patient-specific geometric models. As plaque rupture is a complicated biomechanical process influenced by the structure and constituents of the plaque as well as the external mechanical and hemodynamic forces acting on the plaque, a comprehensive evaluation of lesion geometry, plaque characteristics and hemodynamic parameters may enhance the identification of high-risk plaque and the prediction of ACS risk. In this regard, the current study is designed to evaluate prognostic implications of comprehensive non-invasive hemodynamic assessment using CCTA and CFD in the identification of high risk plaques that caused subsequent ACS.
This multicentre study is to validate prediction modeling for the ACHD population undergoing cardiac surgery. The validation of this prediction model will support and generalize its use as a risk stratification tool in the ACHD population.
The purpose of the study is to monitor the clinical safety and performance of the EXCOR Venous Cannula in context of an EXCOR VAD therapy to ensure continued acceptability of identified risks, to enable detecting emerging risks and to assess clinical improvement on both short- and long-term.
The primary aim of this research is to explore the adherence and drop-out from early cardiac rehabilitation (CR), to inform interventions to support patient's adherence to CR and facilitate maintenance. The secondary aim is to understand which aspects of CR are essential for improving health-related quality of life in the short and long-term. This research will comprise four stages adopting a mixed-methods, quasi-experimental, repeated measures design.
Coronary heart disease (CHD) is a leading cause of premature death in Canadian women. Women who suffer an acute coronary event are more likely than men to be physically inactive, have lower exercise capacity, and die in the next year. The standard cardiac rehabilitation (CR) programs do not meet women's needs. There is a need to address these issues to increase participation in CR. The main purpose of this project is to evaluate the effects of high-intensity interval training (HIIT) compared to moderate-intensity continuous exercise training (MICE) on exercise capacity and quality of life in women with CHD. Positive results of this study will fill the gap in knowledge in exercise training, levels of motivation, self-efficacy and enjoyment following HIIT vs. MICE in women with CHD.
rheumatic heart disease remains the majority valvular disease in low and middle income countries, which mostly affected mitral valve, surgical treatment is the most effective strategy to improve the outcomes of middle or late-stage RHD patient, however, whether mitral valve repair surgery is superior to replacement or other evolving interventional device remains controversial, this study aims to investigate the results of repair surgery compared with replacement or other treatment strategy from international multicenters.
Social technologies for health have already become essential means for providing underserved populations greater social connectedness and increased access to novel health information. However, these technologies have also had negative unintended consequences. The resulting digital divide in social technology takes many forms - from explicit racism that excludes African American and Latinx populations from the resources enjoyed by White and Asian members of online communities, to self-segregation for the purposes of identity preservation and community-building that unintentionally results in limited informational diversity in underserved communities. The result is an often unnoticed, but highly consequential compounding of inequities. This research seeks to use an online social network approach to address these challenges, in which the investigators demonstrate how reducing the online levels of network centralization and network homophily among African American community members directly increases their productive engagement with health-promoting information.
