Some metropolitan regions in the United States have much higher rates of heart attacks than the rest of the country, according to an annual well-being study by Gallup-Healthways.

24/7 Wall St. used data in the study to rank cities with the highest rates of heart attacks. The Reading area ended up at No. 10 on the list, with as many as six percent of people surveyed reporting they had survived a heart attack. The national rate is estimated to be four percent.

The report also found that nearly 33 percent of those who reported having a heart attack were obese, higher than all but eight other metro areas and eight percentage points higher than the national obesity rate.

"In general, residents living in metro areas with high rates of heart attacks also struggle more with chronic health problems like high blood pressure, obesity, and diabetes," Elizabeth Mendes,'s deputy managing editor, told 24/7 Wall St.

Lack of exercise is likely contributing to the problem, the report found, with just 46.4 percent of residents saying they had exercised at least three times for at least 30 minutes in the previous week.

The metropolitan area that topped the list was Huntington-Ashland, W.Va-Ky.-Ohio, with a heart attack percentage of 8.9 percent.

The study was based on interviews with more than 230,000 adults ages 18 and over in 189 metropolitan areas across the country.
