Reading through the whole linked article seems to suggest precisely this too. Unless I'm missing something, all it's saying is that if you exercise routinely for >1 hr at a time it's more likely that a doctor may mistakenly diagnose you with a cardiovascular disorder because of the characteristic changes in your heart as a result of repeated exercise, especially if they're not aware that you do exercise often. So they have to be careful when evaluating patients who exercise for heart conditions so as to not misdiagnose a collection of otherwise benign characteristics as a more severe disease requiring treatment. In short, athlete's hearts are a little different; evaluate patient with this in mind.
