Question

diabetes mellitus with an associated benign hypertension causes which change in the microvasculature of the coronary vessels of the heart? hyperplastic arteriolosclerosis nodular glomerulosclerosis hyaline arteriolosclerosis mesangial proliferation

Explanation:

• Hyperplastic arteriolosclerosis: Associated with malignant hypertension, not benign hypertension.
• Nodular glomerulosclerosis: Seen in diabetic nephropathy (kidney), not coronary microvasculature.
• Hyaline arteriolosclerosis: Characterized by hyaline (glassy - like) material deposition in arterioles. In diabetes mellitus with benign hypertension, the microvasculature of the coronary vessels (and other small vessels) can show hyaline arteriolosclerosis due to chronic hyperglycemia and hypertension - related damage to the vessel walls.
• Mesangial proliferation: Occurs in the glomeruli (kidney) in certain glomerular diseases, not in coronary microvasculature.

Answer:

C. Hyaline arteriolosclerosis
