Resting pulse rate at 69 is good even in spite of the high systolic and diastolic numbers.
Your heart is strong, key point here..there is an issue with your circulatory system that needs to be addressed.
First thing to look at would be diet and weight, experiment with varying diets. If you’re active in the gym, you also need to look at HYDRATION along with that..buy some Celtic Salt and take a very small pinch of it, let it dissolve on your tongue then drink your water to help with the transfusion of minerals between the cells. Protein heavy diets require good attention to fluid intake to maintain adequate hydration.
Cayenne pepper and fresh raw garlic are extremely good heart healthy items to consume in regard to heart health and circulation. You can also get some Nitric Acid, this naturally helps the arteries dilate and allows more oxygen to be carried through the bloodstream helping to lower blood pressure.
Also another thing to remember is that posture affects breathing which affects oxygen intake which in turn affects the heart and blood pressure. Strong core muscles allows for a person to breath fully, deeply without effort..you’ll be surprised how many people don’t pay attention to how they breathe and how the correlates to a myriad of adverse health effects.
