A study from the Johns Hopkins Bloomberg School of Public Health found that healthcare coverage may be a more telling predictor of heart attack and stroke survival than race.

The study found that African-Americans and Caucasians 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 were 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 equipped with affordable health insurance rates.
