Diseases of the cardiovascular system are a common cause of death in renal transplanted patients. In this study we assessed the echocardiographic morphological and functional findings after renal transplantation of two homogenous groups of transplanted patients with normal renal function. The first (A) with spontaneously normotensive patients, the second (B) with moderate hypertension treated mainly with Ace inhibitors. Analysis of these data highlights two noteworthy results: the similar left ventricle hypertrophy found in both groups and the existence of better diastolic compliance among the hypertensive transplanted patients. If this is confirmed by studies currently in progress, the importance of Ace-inhibitors treatment in remodelling cardiac dysfunction after long term dialysis treatment might be seriously considered.
