At the time, the CNN host underwent an angioplasty and also had stents inserted to reopen the previous bypass from a heart attack he suffered in 1987. “He had an episode with his heart over the weekend and he had an artery opened up and some stents put in,” an insider previously told PEOPLE. “But he’s remarkably strong. His doctors even say they don’t know how he bounces back from everything so quickly.” Despite his physical recovery following the procedure, the source says the incident highlighted another unhealthy part of his life: his relationship with Shawn Southwick King.
