I saw this live on NBC and it was horrific. So glad to hear Kemoy seems to be ok and out of the woods--but that he was feeling unwell for a few days prior is worrying....
I lost my good friend Danny Kassap in 2011 ( he was a 2:14 marathoner, and winner of the Toronto marathon) . He had his first bout of AF, likely due to a genetically enlarged heart at age 27. And despite, quite literally, almost dying during the Berlin marathon while running in 9th place (he collapsed and was pronounced dead for 15 minutes while on the course), he was resurrected and recovered. He started to run again 6 months later. I was in the doctor's office with him when the cardiologist strongly suggested he wear a pacemaker for the rest of his life. But Danny refused, and took the chance to run and train again. Over the next year, he was slowly getting back into shape. Not where he was, but back in 31 minute 10k shape. Then one day, after he raced a local race in the morning, he wasn't feeling well all day. He went out for dinner with some friends, and said to them that sometimes his heart would "flutter". Then, that night, he went to bed instead of seeing the doctor after feeling "off". He had a cardiac arrest, and would die before the ambulance arrived. He had just turned 29 years old....All of us who ran so many miles with him still miss him dearly.
If any runner is diagnosed with AF or an enlarged heart (and many will have this--this is indeed a genetic advantage), please don't ignore it. Trust me, it can be devastating. I miss Danny all the time, and run by his grave weekly to remember him. I wish he chose the pacemaker. He would be 37 now.
