If you are an adult in Alabama then your heart might be older than you are. A new government report suggests age is just a number — and perhaps not a very telling one when it comes to your risk of heart attack or stroke. The Centers for Disease Control and Prevention report is meant to spur more Americans to take steps to prevent cardiovascular disease. CDC scientists estimated the average heart age of men and women in every state, based on risk factors like high blood pressure, obesity, and whether they smoke or have diabetes. Then it compared the numbers to average actual ages. According to CDC calculations nearly three out of four U-S adults have a heart that's older than the rest of their body. Mississippi has the highest proportion of adults with advanced heart age, followed by West Virginia, Kentucky, Louisiana and then Alabama. Those states also have higher rates of smoking, obesity, and other heart disease risk factors.
