Tim O'Donnell - heart attack at Challenge Miami

Just saw the youtube upload. Scary stuff, I’m surprised this hasn’t been bigger news earlier. Hope he stays healthy, whether that includes racing or not.

I am just watching the video and starting to remember the entire Steve Larsen scenario. Wow, crazy stuff.

Wow. That happened to a friend of mine who was chasing Kona. Very fit, very fast. Nearly killed him. Scary stuff

Also maybe change title to Tim O’Donnell heart attack at Challenge Miami.

It may interest many in the same age group and above. My first reaction when I saw your title was, “Is he really talking about the guy who was second in Kona pre pandemic at a race in Miami 14 month later ???”

Best wishes to Rinny and Tim. I know that once I became a parent it became way more difficult to take risks in racing and have been cautious pushing my redline

well that vid has a bit of everything. So glad he is ok.

A reminder to all of us of how fragile life can be and what is really important.

Changed to be a bit more tasteful - was just shocked to see it. You hear about this happening to fit people, but not usually THAT fit. I’m surprised that it never popped up for him in blood testing, which I assume T&R do? Unless there wasn’t any signs at all and it really was just a freak incident.

Wow. Total shocker.

I’m glad Tim is fine. Wonder if he’ll get back to racing.

Does anybody know if this sort of blockage is detectable? I imagine a routine ECG or anything else that athletes do on a regular basis wouldn’t give anything away? I really really really wouldn’t like to undergo an event with a 12% survival rate.

I’m very happy that he is doing well and that he put this out there to the public. We need more high profile people to do this to enlighten everyone out there.

I was just thinking about you discussing this in another thread. What tests can we request to assess our risk of this? My doc has for a few years been advocating a carotid ultrasound. Had an echo/ stress test done about 10 years ago, but nothing since then.

I’m fairly young and convinced my Cardiologist/electrophysiologist to perform a cardiac CT on me back in May. He had no issues doing it, although it took some appeals to get my insurance provider on board. I just wanted that added peace of mind knowing I had checked every box I could to ensure my heart is ok.

Good luck to Tim on his recovery, hate to hear about people having these issues!

Also very happy he is okay. Not to derail this thread but has anyone tried the Fourth Frontier ECG strap?

My understanding is most tests detect flow-limiting lesions, that is atherosclerotic plaques that have narrowed the arteries so that blood flow is limited more or less chronically to downstream heart tissue.

Heart attacks, on the other hand, are from the acute ruptures of atherosclerotic plaques (which tends to occur in relatively young ones that haven’t matured very much yet) which leads to a thrombus forming in the artery and acute narrowing if not full blockage of the artery.

I would think the two would be correlated somewhat but I’m not sure how much?

true-stress tests detect ‘flow limiting lesions’

CACS looks for* **any ***plaque-and doesn’t pick up soft plaque so there is a huge difference between 0 and any number.

heart attacks happen when plaque ruptures and then a blood clot blocks off the flow to the artery-and can cause fatal arrhythmia also…

Message to take home:
any activity limiting symptom, like chest discomfort/pressure/tightness, unusual shortness of breath etc should be checked out

I guess the question is how common is it to have no plaques (and I guess be in the clear?) vs. having some older plaques and therefore at risk? And does the CACS metric correlate with heart attack risk?

Like when I had multiple PEs - chest pain and SOB, and over 6 weeks my GP, pulmonologist and cardiologist (plus body scan and stress test) missed it…

Scary stuff for sure. I had the same LAD blockage in Feb, but in my case I was on a training run in Kona and ended up face down in the road in cardiac arrest. Saved by some bystanders who found me and started CPR and the medical team eventually took over and saved my life. It can happen to any of us, so I encourage everyone to stay on top of your heart health even if you are as fit at Tim. No idea if any of the tests would have identified my issues prior to my event, but I wish I had at least stayed more proactive.

Care givers are variably good at their job. I am so sorry for your experience and know that all paths are different.

I just don’t know what to say…

Meh. Nothing to say really, it’s when I learned that medicine can be more art than science.

back to the subject at hand

Wow. Total shocker.

Im 36
Have a 25-49% blockage in my LAD
I’m seeing my cardiologist and have had a second opinion

This is a very detectible thing

This really hits home.
