Guidelines for the detection of coronary artery disease (CAD) and assess of risk in renal transplant candidates are based on the results of noninvasive testing, according to data originated in the nonuremic population. We evaluated prospectively the accuracy of 2 noninvasive tests and risk stratification in detecting CAD (>or=70% obstruction) and assessing cardiac risk by using coronary angiography (CA). One hundred twenty-six renal transplant candidates who were classified as at moderate (>or=50 years) or high (diabetes, extracardiac atherosclerosis, or clinical coronary artery disease) coronary risk underwent myocardial scintigraphy (SPECT), dobutamine stress echocardiography, and CA and were followed for 6 to 48 months.

The present investigation was conducted to study the effect of blood pressure load on the left ventricular mass of recently transplanted patients using 24-h ambulatory blood pressure monitoring (ABPM).
Methods: We studied 30 renal transplant (RT) patients (36.
Background: The aim of this study was to examine prospectively the impact of renal transplantation on the morphological and functional characteristics of the carotid arteries and heart in a group of end-stage renal failure patients without overt cardiovascular disease, followed up for >3 years.
Methods: Twenty-two patients were evaluated 2-3 weeks after renal transplantation, and again 12 and 40 months post-transplant, using high resolution ultrasound imaging and echocardiography.
Results: Kidney and patient survival were 100% at the end of follow-up without any major cardiovascular events.
