A target blood pressure should be in the 115-120/ 70-75. There is compelling level I medical evidence that a persistent BP of 150/80 increases your risk of cardiovascular complication. Excellent job of keeping a BP journal. Record your values several times per day including am and evening and share them with physician. It is important to have tight control. Good luck
hello
your blood pressure depends on a lot of things. Firstly, you should determine if your activities have changed in these 3 weeks. (maybe your exercising intensity as increased or your diet has changed). Although 146/80 (+/- 3 points) does not seems to me a lot of hypertension, but because your have a heart problem you should check with your physician as this could a sign of something.
Hope this helps
