Blood pressure refers to the amount of pressure exerted against the walls of the blood vessels when your heart beats, or pumps blood. The top number - yours is 150, is the systolic. This is when the heart actually beats, or contracts, and is the most pressure exerted against the blood vessel walls. The bottom number - yours is 90, is the diastole. This is when the heart actually relaxes between beats or contractions. It is the least amount of pressure exerted against the blood vessel walls. Depending on your age, 90 would be considered moderately high for a diastolic reading. Normal is below 85. 150 would also be a little on the high side for systolic. Depending on your age, it should be around 120-130. Hope this helps.

What are the new blood pressure ranges? I understand they recently changed, with higher numbers than before that indicate meds are necessary. Aldo, recently read that ranges vary by age, with those over 60 getting a pass on meds until BP reads 150/90. True?
