Working out has its benefits, including a new one revealed in a study from the Johns Hopkins Bloomberg School of Public Health, which found that healthcare coverage may be a more telling predictor of heart attack and stroke survival than race.

Those with private insurance policies lived longer than those who were considered to be underinsured. The study specified that African Americans and whites had similar survival rates when both attached to private plans. Those who did not have a sufficient policy were more than 30 percent more likely to die early if they had a heart attack, while 50 percent more likely to perish if they had atherosclerosis.

"African Americans living in poor, urban neighborhoods bear a high burden of illnesses and early death, from cardiovascular disease in particular," said Derek Ng, lead author of the study. "Our findings suggested that a lack of health insurance, or being underinsured is a major cause of insufficient treatment and subsequent premature death."

If a person is specifically concerned about their heart health, and they don't have a sufficient insurance plan, looking for a more substantive option could be a good idea. Comparing health insurance quotes online may help them find a private plan that is sufficient and is equipped with affordable health insurance rates.
