Heart disease is the leading cause of death in America and across the world. According to the CDC, more than 600,000 Americans will have a heart attack this year. As a result many of us — or someone we love — will one day undergo a coronary angiogram, an X-ray procedure that helps doctors see the heart’s blood vessels and diagnose what’s going wrong.

These are some of the reasons Sandeep Jauhar, author of “Heart: A History” and director of the Heart Failure Program at Long Island Jewish Medical Center in New York, wants to demystify the coronary angiography process. In the video above, he walks through an angiogram procedure, done on a real-life patient at his hospital, to explain to readers how it works, what it looks like, and how it can save a life.

Jauhar will appear on an upcoming segment of the PBS NewsHour to answer more reader questions about “Heart.”
