The answer to your question is "no".
I think when it's someone's time to go, it's their time to go. My father left suddenly, he had a massive heart attack at home. According to the doctors it wouldn't have mattered if he'd had that heart attack at the hospital, nothing would have saved him.
It's terribly sad and I understand your pain. I am so very sorry for your loss. I also know how hard it is to deal with the fact that suddenly your loved one isn't there. Like me, it sounds like you didn't have the chance to say goodbye. If you feel you still have things you want to say, find a quiet and private place, sit down and say them. I can tell you it really helps.
Please try to remember your loved one's life, not his death, and hopefully that will bring you some peace of mind. Be kind to yourself. Post any time if you want to chat some more.
Kind thoughts to you
