In a fanfiction like this, Gabriel's heart attack could be a turning point for Adrien. If he witnesses his father having a heart attack, it would be a huge shock. He might start to question everything his father has been doing. Maybe he'll find out about his father's Hawkmoth identity while trying to help. This could lead to Adrien having to make some really tough decisions, like whether to continue as Chat Noir or give up his miraculous to take care of his father.
In terms of the story arc, Gabriel's heart attack could be the start of his redemption. If he survives, he might have a change of heart (no pun intended). He could see the error of his ways while on the brink of death. This would then lead to a whole new direction for the fanfiction. Instead of the constant fight between good and evil, it could turn into a story of forgiveness and rebuilding. The other characters would have to adjust to this new Gabriel, and there could be a lot of drama and conflict as they decide whether to trust him or not.
