I said MAJORITY of heart attack victims live long enough to make it to the hospital. Minority of heart attack victims suffer a massive attack and die quickly. As happened to my brother at age 79.
Where as if the main aorta has serious break, death is quick from loss of blood pressure.
With my own lifestyle of keeping weight in desired range and daily aerobic exercise for 27 minutes (365 days every year) I have no heart issues and normal EKG every time. Daily exercise has enormous benefits. I Don’t get colds, no flu, covid ran away in 36 hours without any medications, no joint pains, never had a fall, still can modify code of my computer software, play good chess & bridge. Still mowing my huge lawn with push mower. All from daily exercise at age 86.
I'm glad you've enjoyed good health and have made it to 86. I was the baby, and am the last one left. I'll be 79 next month. Everybody in my family smoked but me. Both parents and a sister died of lung cancer. My oldest sister died of a stroke at age 74. Father passed at 72, and mother and other sister passed at 69. I feel like I'm living on borrowed time.
When I responded with my initial comment, I should have taken into account, the advances that have occurred in medicine, and especially with heart issues since my brother passed at 51 in 1995. It's obvious that more people can survive a heart attack, and live longer with the proper treatment. My youngest son, age 55 has already been through Stage 3 colon cancer in 2019, and survived. He is now dealing with the diagnosis of Hypertrophic Cardiomyopathy.
I don't know if you saw it, but I posted a link to an article about the actor John Ritter who passed from aortic dissection in 2003. His family said he was misdiagnosed with a heart attack initially when he got to the hospital.
