[Updated at 6:27 p.m.] Michigan State football coach Mark Dantonio is expected to recover fully from a heart attack that he suffered shortly after his team's trick-play overtime victory against Notre Dame, a cardiologist who treated him said at a news conference Sunday.
Dantonio began experiencing chest discomfort shortly after Michigan State's dramatic 34-31 victory in East Lansing, Michigan, on Saturday night, and went to Lansing's Sparrow Hospital early Sunday morning, Dr. Chris D'Haem said.
"We found one of the vessels that feed blood to his heart muscle to be closed," and D'Haem used a stent "to hold the vessel open and re-establish blood flow to the heart muscle," the doctor said.
"Fortunately, his heart damage was very minimal. I think he's going to do very well. I remain very optimistic for his full recovery," D'Haem said.
Dantonio, 54, was resting comfortably Sunday and is expected to stay at Sparrow Hospital for a few days for monitoring, Michigan State said in a statement.
Dantonio was admitted to the hospital shortly after Michigan State used a fake field goal attempt to beat Notre Dame in East Lansing on Saturday night.
The winning play came after Notre Dame scored a field goal in its overtime possession to take a 31-28 lead. It was fourth down during Michigan State's overtime possession, with the Spartans lined up for an apparent 46-yard field goal attempt. Placekick holder Aaron Bates, who also is the Spartans' punter, took the snap, stood and threw a 29-yard touchdown pass to Charlie Gantt.
The winning gamble pushed Michigan State's record to 3-0. Notre Dame fell to 1-2.
D'Haem was asked whether such a stressful, close game could have triggered the heart attack.
"Certainly stress doesn't cause coronary heart disease, but as we all know, very emotionally or physically stressful events can be the trigger," D'Haem said.
Offensive coordinator Don Treadwell will lead the team while Dantonio recovers.
"Mark Dantonio is our head coach," MSU Athletics Director Mark Hollis said in the school's statement. "Throughout his recovery process, offensive coordinator Don Treadwell will assume the day-to-day responsibilities of the head coach. This is a time for Spartan Nation to rally around Coach D and the football program. We all look forward to his return to the sidelines.
"The thoughts of the entire Spartan family are with Coach D, his wife Becky and his daughters Kristen and Lauren."
