But now, he's back on his feet.
Guin's heart attack landed him in the hospital, where he had a stint put in and started rehab.
Now after rehab, he's working at his cousin's fire work stand during the day.
Guin says they'll get really busy by Friday, but he's feeling great and ready for the rush.
"Yeah, still a little tired, but getting back close to where we were and able to work every day," said Guin. "It's getting back to normal."
Rodney says as long as he keeps active, he's confident he can make it back to 100%.
