BACKGROUND Endothelial dysfunction is a key step in the initiation and progression of atherosclerosis and subsequent cardiovascular complications. We examined whether peripheral endothelial function, as assessed by fingertip reactive hyperemia-peripheral arterial tonometry (RH-PAT), can provide additional clinical value to traditional risk factors for(More)
BACKGROUND Endothelial dysfunction is an early stage of atherosclerosis. Single-nucleotide polymorphisms (SNPs) have been associated with vascular dysfunction, cardiac events, and coronary artery remodeling. We aimed to detect SNPs associated with endothelial dysfunction and determine whether these associations are sex specific. METHODS AND RESULTS Six(More)
BACKGROUND Single nucleotide polymorphisms (SNPs) are the most common source of genetic variation. Although microvascular pathology is associated with cardiovascular events, genetic phenotypes causing microvascular disease remain largely unknown. This study identifies sex-specific SNPs associated with coronary microvascular dysfunction. METHODS AND(More)
OBJECTIVE The ratio of basal distal intracoronary pressure (Pd) and aortic pressure (Pa) is a nonhyperemic index for the severity of coronary artery stenosis. The aim of the current study was to evaluate the clinical usefulness of a hybrid baseline Pd/Pa-fractional flow reserve (FFR) strategy in reducing the need for hyperemia. METHODS In this study, 570(More)
OBJECTIVES This study tests the hypothesis that circulating mononuclear cells expressing osteocalcin (OCN) and bone alkaline phosphatase (BAP) are associated with distinct plaque tissue components in patients with early coronary atherosclerosis. BACKGROUND Plaque characteristics implying vulnerability develop at the earliest stage of coronary(More)
BACKGROUND Myocardial perfusion scintigraphy (MPS) is used widely to assess cardiovascular risk in patients with chest pain. The utility of carotid intima-media thickness (CIMT) and endothelial function as assessed by reactive hyperemia-peripheral arterial tonometry index (RHI) in risk stratifying patients with angina-like symptoms needs to be defined. We(More)
