BACKGROUND Speckle-tracking imaging is a novel method for assessing left ventricular (LV) function and ischemic changes. The aim of this study was to assess the predictive value of two-dimensional longitudinal strain in the detection of longitudinal LV dysfunction and the identification of coronary artery disease (CAD) in patients hospitalized with angina.(More)
OBJECTIVES Myocardial ischemia is difficult to assess by noninvasive methods in patients with a permanent pacemaker. Pacing stress echocardiography (PASE) has been used successfully in the detection of coronary artery disease (CAD). However, there are no data comparing PASE and other methods. METHODS We compared agreement and accuracy of PASE and(More)
OBJECTIVE Hemodynamic forces are potential determinants of aortic atherosclerosis. Aortic regurgitation (AR) alters the flow pattern in the aorta. However, the association between AR and aortic atherosclerosis is not well known. METHODS We assessed the presence, extent and distribution of atherosclerotic lesions in the aorta of 42 patients with chronic AR(More)
BACKGROUND Endothelial progenitor cells (EPCs) have a role in the repair of endothelial surfaces after injury. Reduced numbers of EPCs are related to endothelial dysfunction and adverse clinical events, suggesting that endothelial injury in the absence of sufficient repair by circulating EPCs promotes the progression of vascular disease or valvular(More)
