Abstract

Patients with aortic valve sclerosis (AVS) have an increased risk of cardiovascular events. Patients with atherosclerotic renal artery stenosis (RAS) develop resistant hypertension and heart failure. We hypothesized AVS may be copresent with RAS in hypertensive patients. Hypertensive patients with AVS (n = 167) underwent magnetic resonance (MR) angiography using nonenhanced steady-state free precession (SSFP) technique. More than 75% luminal narrowing in the proximal region of main renal artery was regarded as significant RAS. Peak aortic jet velocity was obtained by Doppler echocardiography. We measured brain natriuretic peptide (BNP), and estimated glomerular filtration rate (GFR) using the Modification of Diet in Renal Disease equation. Unilateral or bilateral RAS was detected in 40 patients. AVS patients with RAS were older (78 +/- 6 vs. 74 +/- 8 years), and had higher levels of aortic jet velocity (162 +/- 4 vs. 144 +/- 3 cm/s), and lower levels of GFR (55 +/- 13 vs. 62 +/- 14 ml/min/1.73 m(2)) than those without RAS. Higher aortic jet velocity (odds ratio (OR) = 1.58, 95% confidence interval (CI) = 1.09-2.31) and lower GFR (OR = 0.54, 95% CI = 0.33-0.38) were associated with the presence of RAS, after being adjusted for a...Continue Reading

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
