In 1964, Holley et al reported data from 295 consecutive autopsies performed in their institution during a 10-month period. [14] The mean age at death was 61 years. The prevalence rate of renal artery stenosis was 27% of 256 cases identified as having history of hypertension, while 56% showed significant stenosis (>50% luminal narrowing). In normotensive patients, 17% had severe renal artery stenosis (> 80% luminal narrowing). In those older than 70 years, 62% had severe renal artery stenosis.

Another similar autopsy study reported similar results, with 5% of patients older than 64 years showing severe stenosis; this figure increased to 18% for patients aged 65-74 years and 42% for patients older than 75 years.
