Jeffrey Dach MD looks at the threshold blood pressure for treatment of hypertension:

jeffreydach.com

Doctor Port introduces a new model which takes into account age and gender. The mortality risk increases steadily with blood pressures that exceed a threshold based on sex and age. The threshold blood pressure formula is 110 + (2/3) (age) for a man aged 45-74, and 104 +(5/6) age for a woman aged 45-74. Here is the Lancet chart for the blood pressure thresholds, showing treatment thresholds based on age and gender.(17) (18)(28)

Age......Male BP Threshold....Female BP Threshold 70th percentile

45..........139.........................142 mm Hg
50..........143.........................146 mm Hg
55..........147.........................150 mm Ng
60..........150.........................154 mm Hg
65..........153.........................158 mm Hg
70..........157.........................162 mm Hg
