Filter by:In this study, the investigators aim to use data identified through the hospital's integrated medical database and National Health Insurance database to explore the long-term performance and benefits of biological and mechanical valves. This research aims to provide more recommendations and references for valve replacement in different patient populations.
Coronary angiography-derived FFR assessment (AngioQFA) is a novel technique for physiological lesion assessment based on 3-dimensional (3D) quantitative coronary angiography (QCA) and virtual hyperemic flow derived from contrast frame count without drug-induced hyperemia. The goal of this prospective, multicenter trial is to compare the diagnostic performance of AngioQFA with invasive FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies of the computational fluid dynamics (CFD)-based index of microcirculatory resistance (IMR) using wire-based IMR as the reference standard.
The PM-Heart algorithm (PMHeartIHD) is an in-house developed software that predict the survival prognosis for the individual patient hospitalized with ischemic heart disease (IHD) after a coronary arteriography has been performed. The software is intended to be used as a clinical decision support system i.e. the calculated survival prognosis is expected to enhance the quality of the treating physician's therapeutic considerations concerning (minor) adjustments to the patients treatment and follow-up - all within the framework of the current medical guidelines. Thus, the algorithm does not "show the physician specifically what to do", but rather ensures a better knowledgebase for the overall interpretation and choice of management of the patient.
This Phase 2a clinical trial will evaluate the effectiveness, safety, and tolerability of increasing dose strengths of an oral daily medication, DFV890, administered for 12 weeks, to reduce key markers of inflammation related to CVD risk, such as IL-6 and IL-18, in approximately 24 people with known heart disease and an elevated marker of inflammation, hsCRP.
This hospital-based retrospective study reviewed patients who underwent surgery for CHD between 2017 and 2020 and analyzed the clinical features and outcomes associated with airway anomalies.
Recent evidences have demonstrated improved diagnostic accuracy for detecting coronary artery disease (CAD) when myocardial blood flow (MBF) is quantified in absolute terms using single photon emission tomography (SPECT) compared to conventional myocardial perfusion imaging (MPI). However, there are no uniformly accepted cutoff values of MBF and MFR derived from SPECT for diagnosing hemodynamically significant CAD. Particularly, the diagnostic performance for quantitative SPECT has not been validated using fractional flow reserve (FFR). The aim of this prospective study is to determine optimal cutoff values of absolute MBF and MFR derived from NaI (Tl)-based SPECT and to evaluate the diagnostic efficacy of this quantitative technology utilizing invasive coronary angiography (ICA) in combination with FFR results as the reference standard in patients with suspected or known CAD.
Coronary artery disease (CAD) is a leading cause of mortality in western countries. Coronary computed tomography angiography (cCTA) is the first-line imaging test in patients with suspected obstructive CAD. However, in most patients, cCTA shows non-obstructive CAD. The management of patients with non-obstructive CAD is unclear. This is due to the lack of cCTA-based methods capable to assess the risk of disease progression towards developing major adverse cardiovascular events (MACEs) based on the atherosclerosis characteristics of each patient. A solution for prognostication in these patients is particularly appealing since it could allow to identify patients who can benefit of a more aggressive medical treatment and management, thus improving outcome. Proposed methods, which include qualitative evaluations such as the identification of adverse atherosclerotic plaque characteristics or quantitative evaluations such as the quantification of atherosclerotic plaque burden, may in some cases suffer of limited reproducibility between operators and software. Most importantly, each single biomarker is insufficient to accurately predict patient risk, hence potential synergic integration of cCTA and clinical biomarkers is the key to efficiently guide the personalization of patient's management. Furthermore, the few risk stratification methods that have been proposed are not designed to work on platforms capable of deploying the solution to other clinical settings, promoting prospective or external validation
This is a single-group, observational study which will involve obtaining two echo scans of recruited patients. All recruited patients will undergo echo scans by both novice users (nurses) and experts (echo sonographers). Image quality between novices and experts as well as the ability to calculate LVEF from novice and expert scans and the quality of the LVEF calculated via KOSMOS-EF compared to LVEF calculations by expert cardiologists will occur in post-hoc Echo image analysis
To evaluate the effect of applying a hybrid protocol (face-to-face and via call center) of breastfeeding assistance and guidance on the duration of breast milk supply to babies with congenital heart disease for 6 months.
This single-arm trial of the Cardiovascular Risk Reduction Among People Experiencing Homelessness (CV-Homes) intervention alone (n=8) will test the perception and feasibility of anticipated study procedures.
