What sort of disease is chronic high blood pressure?

Insidious: Chronic uncontrolled high blood pressure may produce no symptoms until a heart attack, stroke, heart failure, dementia, peripheral arterial disease, or kidney failure appear. Lifestyle and pharmacologic therapies are very effective in controlling the BP and the commensurate reduction in risk. See your doctor.

Genetic plus diet: Genetics plus age plus diet plus inactivity plus obesity or any combination of these.
