Spironolactone prevents eutrophic middle cerebral artery (MCA) remodeling in young stroke-prone spontaneously hypertensive rats (SHRSP). Clinically, it is more relevant to identify treatments that improve vessel structure after hypertension and remodeling has developed. We hypothesized that spironolactone would increase the MCA lumen diameter and reduce the wall/lumen ratio in SHRSP treated from 12 to 18 weeks of age.
