To put recent and future abnormal CMRIs papers in context
1. 2009 cardiac MRI study of elite athletes who had a cold demonstrated MRI abnormalities in 38% during infection, and 48% in follow up.

2. 2011 paper notes that even Late Gadolinium Enhancement (LGE) (thought to be evidence of a irreversible cardiac scar) is seen after other viruses (H1N1) and may reverse https://twitter.com/anish_koka/status/1301810684993429504

3. A review of CMRIs of asymptomatic elite athletes demonstrates MRI abnormalities are frequently found (in sedentary controls too!) https://onlinelibrary.wiley.com/doi/full/10.1002/clc.23360

4. Even the recent German CMRI paper that may have in part caused the Big10 to postpone their season.. noted a high % of controls had abnormalities https://jamanetwork.com/journals/jamacardiology/fullarticle/2768916

Cardiac MRI is a remarkable, highly useful technology in the right patients. Given the ‘abnormal’ findings in clinically normal patients , there is no support right now for chasing normal couch potatoes or elite athletes with this technology.

And despite all these abnormalities being discovered on cardiac MRIs of normal young folks that have lead some to diagnose myocarditis ( https://www.dispatch.com/news/20200911/ohio-state-discovers-new-way-to-identify-heart-inflammation-in-athletes-with-covid?template=ampart ) myocarditis causes a TOTAL of 75 deaths per year in young people https://www.myocarditisfoundation.org/wp-content/uploads/MyocarditisAndSuddenDeath.pdf
