After a long bike ride, the troponin T blood test is more likely to show a heart attack signal than the troponin I test—even when the heart is healthy.

Similar Assertions

After riding a long bike race, people’s hearts release more of a protein called troponin, especially women, and this spike happens faster in some tests than others.

82%

The blood tests used to diagnose heart attacks can’t tell the difference between a healthy athlete’s post-race troponin spike and a real heart attack.

81%

Beginner runners still show signs of heart stress a day after a marathon, but experienced runners’ hearts look normal again by then.

78%

Experienced runners have less heart cell damage after a marathon than beginners, even though everyone’s heart gets stressed.
