Answers from Sheldon G. Sheps, M.D. Yes. If you have a diastolic number â the bottom number of a blood pressure measurement â less than 90 millimeters of mercury (mm Hg) and a systolic number â the top number of a blood pressure measurement â greater than 140 mm Hg, you have a common type of high blood pressure called isolated systolic hypertension.
In the past, it was commonly thought that the diastolic pressure or bottom number was the most important blood pressure number. This mistaken idea dates back to one of the early studies of the treatment of blood pressure, where only patients with diastolic blood pressure over 90 mm were allowed into the study.
