One in every four deaths in the U.S. is from heart disease. Every year, more than 700,000 people suffer heart attacks (though they aren't always fatal). In other words, heart disease is a big problem, but it doesn't have to be. There are things we can do to prevent heart disease and its consequences.
One big step is to quit smoking. Within one year of quitting, you reduce your risk for heart disease by half. After 15 years of no smoking, your risk is the same as non-smokers.
