Druff have you watched any of the videos in this thread? Your belief that blood pressure is almost entirely hereditary is incorrect. It's old school thinking that is rapidly changing. Your gene expression is impacted by life style.
Have you or any of your parents or grandparents ever attempted a very healthy lifestyle? I can look at you and know for a fact you eat like shit. I'd also be willing to make a bet, up to $1000 that your own personal blood pressure would improve if you adopted a low sodium, zero sugar diet, exercised a bit and ate a lot of fresh vegetables, fruit and healthy fats. I think there are ways a bet like this could be managed, even starting with a set weight loss number.
I know this because I changed mine dramatically and studies are conclusively proving it to be true. It's totally correct that you are born with a certain set of genetic traits but how your genes express themselves can be lifestyle dependent. Read up on epigenetics and the influence we have on gene expression.
The first paragraph in this study explains that you're incorrect.

6. Conclusions
We are entering a new era of understanding how the genome interacts with the environment to affect disease pathogenesis. There is now emerging evidence that epigenetic, as well as genetic, factors are key players in regulating and maintaining blood pressure, and strong evidence for a complex interaction of genetic and environmental factors that influence the risk of HT in each individual
