Uncontrolled high blood pressure is indirectly responsible for many deaths and disability resulting from heart attack, stroke, and kidney failure. According to research studies, the risk of dying of a heart attack is directly linked to blood pressure, especially systolic hypertension. The higher your blood pressure, the higher your risk, even with blood pressure in the normal range.
However, the progress of heart disease caused by high blood pressure can be slowed down. High blood pressure has become the second most common reason for medical office visits in the
