Better Blood Pressure, Longer Life?
Study: Normal Midlife Blood Pressure Lengthened Life by 5 Years

June 28, 2005 -- Controlling blood pressure may lengthen life and keep heart disease away.
That may sound familiar. Now, researchers are driving the message home.
Men and women with normal blood pressure at age 50 lived five more years than those with higher blood pressure. They also avoided heart disease for a longer time.
So say Oscar Franco, MD, DSc, and colleagues in the journal Hypertension. Franco is a scientific researcher in the University of Rotterdam's public health department.
Why Blood Pressure Matters
You could have high blood pressure and not know it. Lots of people do.
About one in three U.S. adults has high blood pressure. But nearly a third of them don't know it, says the American Heart Association (AHA).
Blacks are especially hit hard. More than 40% of black U.S. adults have high blood pressure. It often starts younger and is more severe for them compared with other races, says the AHA.
High blood pressure raises the risk of heart disease, stroke, heart failure, and kidney failure.
But the complications caused by high blood pressure can be avoided by treating the disease. A healthy diet, stress control, and an active, nonsmoking lifestyle are important. Some people may also need help from medicine.
High blood pressure does its damage quietly. It's easily flagged by a quick, painless test.
The test yields two numbers. The "top" number is called systolic blood pressure, which measures the pressure on blood vessel walls when the heart beats. Systolic pressure may be more important as one begins to age. The association between complications due to high blood pressure and high blood pressure is continuous -- the higher the blood pressure, the higher the risk of complications.
The "bottom" number is diastolic blood pressure -- the pressure on blood vessel walls in between beats.
The AHA's standards for adults are:
- Normal: Less than 120/80
- Borderline (prehypertension): 120-139/80-89
- High: 140/90 or higher
