It may seem like a stupid quesiton but my father suffered a fatal acute ruptured MI last week (with clot in circumflex artery). I'm worried that he suffered. I was there. He showed about 2 mins of discomfort in his chest while talking on the phone, then he just stared at the wall in front of him, took a sharp intake of breath, then fell forward. He had no heart problems before this, although we thought he was unwell with a mild stomach bug for two days....we were wrong. He then started the 'death rattle' noise.....me and neighbours tried to resuscitate, unfortunately i let valuable minutes pass with panic and calling the ambulance/neighbours. He was being resuscitated for about 1 hour and a quarter, at home and at the hospital. I'm worried that he suffered. I'm worried that we all just made everything worse for him. he didn't seem concious, but he might have known what was going on. I think i'll be heartbroken forever.
