Summary 1. We compared the serum and aortic lipid levels in spontaneously hypertensive rats (SHR) and Dahl salt‐sensitive rats (DSR) fed a high‐cholesterol (HC) diet. 2. In SHR fed the HC diet, the serum cholesterol level significantly increased, but no aortic cholesterol deposition was observed. 3. The serum cholesterol level in DSR fed the HC diet markedly increased compared to that in DSR fed the basal diet, and this change was greater with the diet containing 8% NaCl than 0.4% NaCl. A significant increase in the content of aortic cholesterol, notably cholesteryl ester, was observed in only DSR fed the HC diet containing 8% NaCl. 4. These results suggest that the combination of hyper‐cholesterolaemia with salt‐induced hypertension acts as a greater risk factor for atherosclerosis than that with genetic hypertension.
