    it's so crazy how doctors can take another artery, and replace it in the HEART, keeping a patient alive. IT'S– wow. mad respect to doctors out there.
  • My grandma has actually had 2 heart attacks, and she's still alive. She is the luckiest person I've ever met, and she's doing just fine today.
  • My dad survived a heart attack in his 40s after that he started doing yoga and diet. Altough now he has started eating normally without any worries but he still does yoga and exercises, And he is the fittest in our family.
  • My dad had a heart attack back in 2020. One of the reasons was the stress, because a few weeks earlier we had a strong earthquake, and corona situation. He said that the lighting darkened, and that he felt his chest swelling, and couldn't move. I was having an online class, and had my camera and microphone off because I was crying. He recovered really fast, and was back in 3 weeks. I now truly appreciate the time we all spend together. He quit smoking a few years earlier, and doesn't eat breakfast, but overly eats lunch. I hope anybody who is going through the same situation I went trough knows that they aren't alone, and that they should stay strong. Love to everybody

    My grandpa had an heart attack ongoing for 3 days. He was in his seventies. He's still alive to this day; the doctor said it was a miracle that he survived

    Back on December 30th 2021, my father had a massive heart attack in his sleep that was caused by pneumonia and covid. And despite the best efforts of the paramedics, he wasn't able to pull through. That morning, my mother said she woke up around 5:00 that morning to him making some sort of humming noise which went on for several seconds. It ended with an aggressive snore/cough and she poked him to see if he was alright, but he wasn't responding. At that point, panic started settling in and she was able to get him on the floor to call 911 and perform CPR. One of my younger sisters who slept next door woke up to her talking on the phone went in and immediately got 2 of my sister up and woke up me and my other 2 brothers. One of my other brothers went up and took over for my mother. What I remember was waking up to my sister yelling at me to wake up and telling me what was happening. The lights were on in my room and it was still dark our. It didn't really sink in what was happening until I got upstairs and looked down the hallway to my left. And what I saw in that bedroom made me feel sick. I just saw him laying on the floor motionless and unconscious. As my mother was saying "1, 2, 3, 4" I could hear it in her voice that she was doing everything she could do to stay calm and not loose it. I wanted to go back and see if I could do anything to help but I decided against that because when you're trying to save a life you need all your focus, you can not afford even the slightest of distractions. So I decided against that. Anyway the only thing I could think to do was to watch out for the paramedics or any emergency vehicle. My 5 younger siblings were all sitting on the couches in the living room stunned and I was nervously pacing back and forth waiting for the emergency vehicles. So when they came they took over, but unfortunately, to no avail. For me, it didn't sink in untile the peiple from the funeral home had to come and take away his body. Even 6 months later, the grief and trauma is still there. And I've used this as motivation to get in better shape. Rest In Peace, Dad.
