BACKGROUND Limited studies report on the additional prognostic value of coronary computed tomography angiography (CCTA) and the coronary artery calcium score (CACS). METHODS For a median of 637 days, 1551 outpatients with chest pain, without known coronary artery disease (CAD) and low or intermediate pre-test probability of CAD, were followed for major adverse cardiac events (MACE), defined a...

Circulating angiogenic cells (CACs) are monocyte-derived cells with endothelial characteristics, which contribute to both angiogenesis and arteriogenesis in a paracrine way. Interferon-β (IFN-β) is known to inhibit these divergent processes in animals and patients. We hypothesized that IFN-β might act by affecting the differentiation and function of CACs. CACs were cultured from peripheral bloo...

BACKGROUND Coronary artery disease (CAD) is the leading cause of mortality and morbidity worldwide. Aortic elasticity and diastolic functions are helpful parameters in assessment of CAD. In this study we aimed to learn whether diastolic function and aortic elastic properties measured by echocardiography are associated with coronary calcium score (CACS), epicardial fat volume (EFV), and plaque a...

BACKGROUND The factors that determine the different patterns of venous anatomy are not well understood. This study was designed to evaluate the relationship between variation in the cardiac vein system and the extent of coronary artery calcium score (CACS). METHODS We reviewed the results of 64-slice CTs of 226 subjects (age 57.2 ± 11.2; 133M) enrolled in our study. The subjects were divided ...

BACKGROUND AND OBJECTIVES It is known that coronary artery calcification (CAC) develops in chronic kidney disease (CKD) before initiation of renal replacement therapy, and factors associated with CKD mineral and bone disorders (CKD-MBDs) are involved. However, little information is available about any association between plasma levels of asymmetric dimethylarginine (ADMA), insulin resistance, a...

AIM Prior evidence observed no predictive utility of coronary CT angiography (CCTA) over the coronary artery calcium score (CACS) and the Framingham risk score (FRS), among asymptomatic individuals. Whether the prognostic value of CCTA differs for asymptomatic patients, when stratified by CACS severity, remains unknown. METHODS AND RESULTS From a 12-centre, 6-country observational registry, 3...

BACKGROUND/AIM Vascular calcification is common and contributes to increased cardiovascular mortality in hemodialysis (HD) patients. In this prospective study, we aimed to investigate the associations of serum S100A12 in the presence of severe coronary artery calcification (CAC) and the progression of CAC in HD patients. METHODS Sixty maintenance HD patients and 30 controls were enrolled. Ser...

BACKGROUND Blood-derived circulatory angiogenic cells (CACs) and resident cardiac stem cells (CSCs) have both been shown to improve cardiac function after myocardial infarction. The superiority of either cell type has long been an area of speculation with no definitive head-to-head trial. In this study, we compared the effect of human CACs and CSCs, alone or in combination, on myocardial functi...
