Atherosclerotic renovascular disease (ARVD) is associated with heart disease. There has been no systematic study of cardiac structure and function in patients with this condition. In this study, the epidemiology of cardiac changes and their relationship to renal function, renovascular anatomy, and BP are delineated. With the use of a cross-sectional design, 79 patients with ARVD and 50 control patients without ARVD underwent echocardiography and 24-h ambulatory BP monitoring. Clinical and biochemical data were collected. Results were analyzed according to renal function, residual renal artery patency, and unilateral or bilateral ARVD. Only 4 (5.1%) patients with ARVD had normal cardiac structure and function. Patients with ARVD (age 70.7 +/- 7.5 yr; estimated GFR 36 +/- 19 ml/min) had significantly more cardiovascular comorbidity (77.2 versus 42.0%; P &lt; 0.001), greater prevalence of left ventricular (LV) hypertrophy (78.5 versus 46.0%; P &lt; 0.001) and LV diastolic dysfunction (74.6 versus 40.0%; P &lt; 0.001), and greater LV mass index (183 +/- 74 versus 116 +/- 33 g/m2; P &lt; 0.001) and LV end-diastolic volume index (82 +/- 35 versus 34 +/- 16 ml/m2; P &lt; 0.001) than control subjects. BP was similar for both patient groups. For patients with ARVD, neither renal function nor renal artery patency predicted a difference in echocardiographic or ambulatory BP monitoring parameters. Patients with bilateral ARVD had greater LV mass index and LV dilation than patients with unilateral disease. Patients with ARVD exhibit a high prevalence of cardiac morphologic and functional abnormalities at early stages of renal dysfunction. Such patients must be identified early in their disease course to allow risk factor modification.
