Yes, BP at or above 140/90 mmHg over a period of time can/will cause CAD.

Thanks Ken, could my hypertension have contributed to my diagnosis of CAD?
If your blood pressure was consistently higher than the normal 120/80, there should be treatment to help prevent cardiovascular disease. Years ago blood pressure that was 139/90 was not considered high enough to treat and was referred to as pre-hypertension BB and watch, but recommended diet, exercise, etc.
The medical community now considers any pressure higher than 120/80 should be treated.
If you PB was over 139/90 in 1968 consistently, there should have been some intervention. Doctors acknowledge that BP could be higher than normal when visting and having a test, but there should have been a followup exam or at least provide instructions to how BP can be reduced with the proper diet, etc.
Thanks for you question and sharing your experience. Take care,
Ken
