Deaths Linked to Cardiac Stents Rise as Overuse Seen

When Bruce Peterson left the U.S. Postal Service after 24 years delivering mail, he started a travel agency. It was his dream career, his wife Shirlee said.

Then he went to see cardiologist Samuel DeMaio for chest pain. DeMaio put 21 coronary stents in Peterson’s chest over eight months, and in one procedure tore a blood vessel and placed five of the metal-mesh tubes in a single artery, the Texas Medical Board staff said in a complaint. Unneeded stents weakened Peterson’s heart and exposed him to complications including clots, blockages “and ultimately his death,” the complaint said.
