Have small vessell disease of the brain and the heart that causes severed headache when I over exert and I have chest pain and jaw what treatment?

Tough problem. I can't make recommendations, but diffuse small vessel disease can be tough to manage. Stents and bypasses to the heart need a minimum diameter and only work with discrete blockages not a narrowing of an entire vessel. Treatment often involves anti-platelets (aspirin etc) aggressive diabetes control, cholesterol control, diet, weight loss. Talk with your doctor maybe second opinion if not happy.
