Is screening the answer?
Harrington: Let’s talk about that because screening is the area, I would say, with the most controversy – and a large amount of emotional controversy. Some argue that the data are not good enough to screen, or doctors are saying, “Wait a minute, why are we screening all these kids?” You said you were at your son’s high school doing CPR training. How many athletes are at his high school? There are many, and that’s a pretty small high school. Big communities, big universities, and the professional sports can afford it. Should we be doing this at the community level?
Patel: There have been some data. The Italians have done standard screening for some time, and it’s shown us that if you did echocardiograms in many individuals, you do find some cases that are hypertrophic cardiomyopathy in pathology. The issue is just how much you have to do and the resource utilization. I think as we get to a world where screening studies can happen with smaller technology and AI, that can be democratizing in how we get to athletes.
Harrington: Give an example of that. We were talking outside, you and I, about some of the new stethoscope technology.
Patel: Yes, stethoscopes are going to be one of the examples. We have stethoscopes that have the ability to get sounds and ECG signals, or at least some lead signals.
Harrington: Yes.
Patel: Potentially you can imagine that sound and ECG tracing in an AI environment, at least getting you from “everyone gets a listen with one stethoscope in their gym from their coach,” and it goes to the cloud. When there are enough questions, these are the ones that have to go further. Now, that’s a big study that has to be carried out; I’m not in any way saying we should do that.
Harrington: The technology is coming.
Patel: We start to see that our ability to rapidly do something to meet our athletes or our patients where they are will happen soon. Remember that the performance curve can vary, but once you have a sound where you can start to say that this is a regular flow murmur vs. “I’m worried about this,” especially as you mark it with ECG – that’s one example.
Smaller imaging is another example. For many years, ECGs have been talked about. There are entire courses that we run looking at ECGs in athletes. Remembering that Aaron Baggish and others are publishing that these individuals are large. When we look at their hearts, we see that they’re large, but when you adjust for size, often you can identify that many of them are within what we think are normal. Structurally, there are still many cases where you look at hearts and you’re asking, “Is this a thick heart? Is this noncompaction? Is this some pathology?”
That’s where you need imaging expertise. I think you have to have those individuals. I’m not advocating screening. I’m advocating studying it and that we should be thinking about the population. I don’t see a world where we don’t eventually start to really look to prevent those.
Harrington: Right. Whether it’s understanding that there are certain risk factors associated with this and we have to dedicate screening resources to those individuals, or if we want to do it more broadly on the population level to understand this with deeper dives into certain individuals, we’ve got to study it.
Patel: Some of the experts in sports medicine and sports cardiology have been collecting these data for a while. It’s time that we are there, because with these events we have the opportunity to share more of these data and maybe raise awareness – not in the teachable moment only – to get others to contribute.
I do believe that long term there’s an opportunity. We’ve seen that. We see that the rates, unfortunately, for marathon runners, where people unfortunately have events, seem to be higher. And we’ve seen the studies on troponin leaks in these individuals or evidence that there’s some effect on the heart from these events. We want people to be able to be long-term healthy.
