Pilot Study of Myocardial Effects Following an Endurance Race

April 23, 2019 updated by: Fredrik H Nystrom, University Hospital, Linkoeping

A Pilot Study of the Myocardial Effects of an Endurance Race as Evaluated by Computer Tomography

Ten healthy subjects perform a baseline computer tomography (CT) of the heart and routine laboratory blood tests for myocardial injury and inflammation.

The same data are collected <24 hours after an endurance race corresponding to a maraton run (i.e. about 40 km of running and/or about 2.5 hours hard training or more). A third collection of lab tests and CT is done a couple of weeks after the race. Magnetic resonance imaging is also performed in parallell to the CT on occasions 2 and 3 in most subjects, serving as a reference for determination of myocardial blood flow.

Detailed Description

Ten healthy subjects perform a baseline computer tomography (CT) of the heart and routine laboratory blood tests (troponin T, hs-CRP, CK-mb etc) for myocardial injury and inflammation.

The same data are collected <24 hours after an endurance race corresponding to a maraton run (i.e. about 40 km of running and/or about 2.5 hours hard training or more). A third collection of lab tests and CT is done a couple of weeks after the race. Magnetic resonance imaging (MRI) is also performed in parallell to the CT on occasions 2 and 3 in most subjects, serving as a reference for determination of myocardial blood flow. The CT of the heart includes contrast injection and blood flow will be determined by a recently developed based on very powerful computers using "machine learning".
