Filter by:Angina is form of chest pain that is due to a lack of blood to the heart muscle. Angina is commonly triggered by stress and exertion, and is a common health problem worldwide. The diagnosis and treatment of angina is usually focused on detection of blockages in heart arteries, and relief of this problem with drugs, stents or bypass surgery. However, about one third of all invasive angiograms that are performed in patients with angina do not reveal any blockages. Many of such patients may have symptoms due to narrowings in the very small micro vessels (too small to be seen on an angiogram). The purpose of this research is to undertake a 'proof-of-concept' clinical trial to gather information as to whether routine tests of small vessel function in the heart might help identify patients with a stable coronary syndrome due to a disorder of coronary function (vasospastic or microvascular angina), and appropriately rule out this problem in patients with normal test results. The diagnostic strategy enables stratification of patient sub-groups to optimized therapy (personalised medicine). Evidence of patient benefits in this study would support the plan for a larger study that would be designed to impact on healthcare costs and patient reported outcome measures (PROMS).
This study aim to evaluate whether intensive lipid lowering therapy may improve the clinical outcomes in coronary artery disease patients with in-stent neoatherosclerosis, in comparison with standard therapy.
Quantitative Flow Ratio (QFR) is a novel method for evaluating the functional significance of coronary stenosis. The purpose of the FAVOR II China study is to evaluate the diagnostic accuracy of on-line QFR with FFR as the reference standard. The secondary purpose is to compare the diagnostic accuracies between online QFR and online QCA, with FFR as the reference standard.
This study builds, in part, upon preliminary results generated as part of the Pharmacogenomics Anti-Platelet Intervention (PAPI) Study (NCT00799396). The purpose of this investigation is to assess the impact of genetic variation in the carboxylesterase 1 (CES1) on response to clopidogrel as well as dual antiplatelet therapy (i.e. clopidogrel and aspirin), as assessed by ex vivo platelet aggregometry, in healthy Amish individuals. The investigators hypothesize that participants who carry alleles that modify the activity or expression of CES1 will have altered response to clopidogrel as well as dual antiplatelet therapy.
Background: Detection of coronary artery disease (CAD) is important due to its high prevalence and its medical and economic implications. Purpose: A systematic review of the diagnostic performance of stress echocardiography (Echo), SPECT, cardiac magnetic resonance (CMR), CT Perfusion (CTP) and PET versus invasive coronary angiography (ICA) or fractional flow reserve (FFR) using hierarchical summary ROC (HSROC) methods. Data Sources: MEDLINE, EMBASE and SCOPUS for literature published in English or Spanish from January 1970 to December 2015. Study Selection: For inclusion, studies had to meet the Cochrane guidelines, had to evaluate the sensitivity and specificity methods, and use ICA and/or FFR. Only those studies with STARD methodology ≥60% were included. Data Extraction: Ten investigators extracted patient and study characteristics and 4 resolved any disagreements.
Patients with coronary artery disease (CAD) were enrolled. CAD was diagnosed by coronary angiography which also resulted Syntax score. Images of left and right ears were captured by a digital camera. Frank score of each patients was calculated based on characteristics and numbers of wrinkles of the earlobes. Statistic analysis were carried out to analyze the correlation between Frank Score and Syntax Score.
TEMA-HF 1 Long-Term Follow-up study is a follow-up study of TEMA-HF 1. It assessed the long-term impact of a 6-months telemonitoring program in chronic heart failure patients.
Coronary Computed Tomographic Angiography (CCTA) is emerging as the diagnostic test of choice in chest pain patients with low to intermediate probability of coronary artery disease (CAD). Qualified CCTA readers may not be available around the clock in most centers, limiting the use of CCTA. This study aimed to determine if well-qualified CCTA technicians can provide initial accurate diagnosis to guide initial management and triage of such patients
This platform will enable investigation the cardiovascular risk reduction and the increase in participant engagement in their heart-healthy goals, through the use of virtual care/telemedicine with a digital platform that connects them to their own doctors, nurses, and dietitians.
Main aim of the COMBAT-CAD-Study is to clarify, if the combination of stress testing with biomarkers improves the diagnostic accuracy. Hypothesis of our study is that diagnosis of CAD can be improved by adding biomarkers to solely stress testing for the workup of patients with suspected CAD or progress of already known CAD.
