What Bernie Sanders' 2 Stents Mean for His Health

Dr. Mehmet Oz has some important medical advice for Democratic presidential candidate Bernie Sanders. The U.S. senator from Vermont underwent emergency heart surgery Tuesday after suffering chest pains. He canceled all upcoming events until further notice after the 78-year-old had two stents inserted. Inside Edition spoke to Oz about the procedure. "A stent is a mesh, it looks like metal, and it pushes open the plaque that's otherwise compromising the inside of a blood vessel," Oz said.
