As the Sound of Ideas team prepares for 2010, we bring you a week of some of our best science shows of the year. Today we reprise a conversation from last May about heart disease. It's the nation's number one killer, but often, the diagnosis comes without an emergency or a heart attack. So what happens then? Bypass surgery? Stents? Drugs? A better diet? As part of Heart Stories, ideastream's multimedia series on heart health, we talked to two top heart doctors from the Cleveland Clinic and University Hospitals. Monday morning at 9, we discuss the risks and benefits of treatment choices and answer questions about how to live with -- and prevent -- heart disease.
