Filter by: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.
The purpose of this study is to prospectively evaluate the effectiveness of low-volume contrast media (CM) injection protocols adapted to tube voltage in patients undergoing Coronary Computed Tomography Angiography (CCTA).
Type 2 diabetes mellitus (type 2 DM) is an important disease with increasing prevalence worldwide. More than 60% of diabetes patients die of CVD. Diabetes is associated with 2-to 4- fold increase in the risk of coronary artery disease (CAD). Diabetes patients with stable ischemic heart disease may have more prevalent of asymptomatic ischemia or silent ischemia due to autonomic neuropathy. Therefore, detection of total myocardial ischemia including both symptomatic and silent ischemia using ambulatory electrocardiogram monitoring may provide better accuracy in ischemic burden and prognosis in diabetes patients. DDP-4 inhibitors have favorable effects on atherosclerotic risk factors beyond glycemic control. Furthermore, DPP-4 inhibitors may have favorable effects on ischemic preconditioning in patients with CAD. For this study we aim to compare the effects of between vildagliptin and Dapagliflozin on ischemic burden defined by total ischemic time, markers of autonomic function, biomarkers of myocardial injury and biomarkers of inflammation.
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.
Accurate measurements from a non-invasive test like myocardial perfusion positron emission tomography/ computed tomography (PET/CT) may decrease the need for invasive procedures such as cardiac catheterization.The investigators wish to see if the measurements from cardiac catheterization can be predicted using a non-invasive 13N-NH3 digital PET/CT scan.
The purpose of this study is to propose a new method for evaluating coronary artery calcium scores (CACS) in individuals with coronary artery disease.
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.
