OBJECTIVES The purpose of our study was to assess the prevalence and extent of coronary artery atherosclerosis in asymptomatic patients with vascular erectile dysfunction (ED). BACKGROUND An association between ED and ischemic heart disease has been suggested, but it is unknown if it represents a marker of subclinical coronary atherosclerosis. METHODS(More)
PURPOSE Restenosis of a coronary artery treated with stent implantation is a well-known process that can compromise over time the success of a coronary angioplasty and, accordingly, treated patients must undergo periodic controls. We have recently witnessed a shift towards a greater use of Multi-slice CT (msCT) in the study of coronary disease without its(More)
Fifty-two consecutive asymptomatic patients with a total of 166 bypass grafts were investigated by 16-slice computed tomography (CT) 15 +/- 5 days before invasive coronary angiography. Overall, 165 grafts (99.4%) were assessable with multislice CT (MSCT). Coronary angiography showed that 111 grafts (67%) were patent and 54 (33%) were occluded. Of the patent(More)
BACKGROUND Follow-up of coronary artery bypass after cardiac surgery is routinely performed by means of X-ray coronary angiography. However, this is an invasive procedure, expensive and includes ionizing radiation exposure, hospitalization and a small risk of complications. Multislice computed tomography is a noninvasive diagnostic tool that permits the(More)
BACKGROUND Patients affected by end-stage renal disease (ESRD) demonstrate a very high cardiovascular risk mediated by traditional cardiovascular risk factors as well as abnormal mineral metabolism and a state of chronic inflammation. Sevelamer is a nonabsorbable non-calcium-based hydrogel with potential antiatherosclerotic properties. METHOD AND RESULTS(More)
Increased arterial stiffness is a marker of vasculopathy in chronic kidney disease (CKD) patients, suggesting a significant cardiovascular damage. Detection of arterial stiffness provides physicians with useful prognostic information independent of traditional cardiovascular (CV) risk factors. In addition, this knowledge may help guide appropriate(More)
Vascular calcification is associated with an adverse prognosis in end-stage renal disease. It can be accurately quantitated with computed tomography but simple in-office techniques may provide equally useful information. Accordingly we compared the results obtained with simple non-invasive techniques with those obtained using electron beam tomography (EBT)(More)
BACKGROUND Vascular and valvular calcifications are a common finding in chronic kidney disease (CKD) patients and are associated with increased morbidity and mortality. We investigated the hypothesis that calcification of the cardiac valves is a marker of coronary artery calcification (CAC) and thoracic aorta calcification (AoC) in hemodialysis (CKD-5)(More)
BACKGROUND AND OBJECTIVES Calcification of the mitral and aortic valves is common in dialysis patients (CKD-5D). However, the prognostic significance of valvular calcification (VC) in CKD is not well established. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS 144 adult CKD-5D patients underwent bidimensional echocardiography for qualitative assessment of(More)
Increased aortic stiffness, as measured by pulse wave velocity (PWV) and augmentation index (Aix), and vascular calcification have been associated with an unfavourable cardiovascular outcome in hemodialysis patients. However, the majority of data have been published in white patients and epidemiological data are discordant on the fate of patients of(More)
