Abstract :
Abrupt onset of renal ischemia is associated with increased blood pressure (BP), but it is unknown whether BP remains elevated in patients with chronic severe atherosclerotic renal artery stenosis (RAS). Patients undergoing coronary angiography who had concurrent renal angiography were divided into 3 groups: severe (stenosis ≥70% diameter reduction), moderate (10%–69%), and minimal RAS. Aortic BP was measured at the time of angiography. Renal angiography was performed in 762 (5.4%) of 14,181 patients undergoing coronary angiography. The mean age was 62 ± 12 years, 52% were women, 93% had hypertension, and 42% had diabetes mellitus. Minimal, moderate, or severe RAS was found in 62%, 30%, and 9% of patients. Patients with minimal RAS were younger, less likely to have hypercholesterolemia or coronary artery disease, and had a lower creatinine than patients with severe RAS. Severe RAS was associated with a lower diastolic BP and mean BP and a higher pulse pressure (PP), but there was no difference in systolic BP or the number of antihypertensive medications between the 3 groups. The degree of RAS had a weak positive correlation with PP, a weak negative correlation with diastolic BP, and almost no correlation with systolic BP or mean BP. In multivariate linear regression analysis, there was an association between severity of RAS and PP but not with mean BP or systolic BP. In conclusion, PP, but not systolic BP, diastolic BP, mean BP, or number of antihypertensive medications, was elevated in patients with severe RAS.
