Abstract

Aim: To examine the association between renal vasculature changes and generalized atherosclerosis using autopsy cases.
Methods: We histologically examined 107 autopsy patients(mean age, 68.4 years; 64% men; 81% non-CVD) to investigate the association between renal vasculature changes and generalized atherosclerosis. We measured the intima/media(I/M) ratio for the renal, intrarenal and systemic arteries(coronary, cerebral, common carotid and common iliac), calculated the rates of arteriolar hyalinization and global glomerulosclerosis and evaluated the frequency of advanced lesions(AHA classification ≥IV) in the systemic arteries.
Results: The I/M ratios of the renal and intrarenal arteries and the rate of global glomerulosclerosis increased with age, while the rates of arteriolar hyalinization and global glomerulosclerosis were associated with diabetes and hypertension(all p<0.05). The I/M ratio of the coronary artery was independently associated with the rate of global glomerulosclerosis(p<0.05). The frequency of advanced atherosclerotic lesions in the coronary and cerebral arteries was also correlated with the I/M ratio of the renal artery and rates of arteriolar hyalinization and global glomerulosclerosis(all p<0.05). The frequency of advanced lesions in the cerebral and common carotid arteries was independently associated with the I/M ratio of the renal artery and the rate of renal arteriolar hyalinization(odds ratio(OR) with [95% confidence interval]; 5.09 [1.15-27.9] and 4.11 [1.38-13.9], respectively).
Conclusions: The results of this study demonstrated that pathological changes in four portions of the renal vasculature differ. Renal vasculature changes except the intrarenal arteries were significantly associated with those observed in the cerebral, common carotid and coronary arteries.
