Oh my gosh, that is tragic. I'm very sorry for your loss. No, you did not cause that. He'd had a heart attack. I'm surprised he wasn't in a rehab facility 7 days after a major coronary event. I would not look for other reasons as to why it happened other than his compromised cardiac health that HE had. Did this happen recently? hugs
No. Heart attacks are the result of heart disease, and while sudden shocks can trigger them, the heart has to be in a weakened state for it to fail. As for you snapping at him, that doesn't qualify as a sudden shock -- that's what married couples do because they care about one another. You had nothing to do with it. I'm so sorry for your loss.
