Lower heart risks

Posted:

Heart disease is the number one cause of deaths across the planet.

But thanks to behavioral changes, new medications and treatments, that rate is falling.

Canadian researchers followed coronary heart disease patients from 1994 to 2005.

During that period -- deaths fell 35-percent.

The study appears in this week's Journal of the American Medical Association video and shows an increased use of medications like beta blockers during the study period.

Not all the results showed decline.  Researchers found a six percent rise in overall cardiovascular deaths from diabetes and two percent from obesity.
