We have plenty of sophisticated gear to understand heart problems. For COVID-19, we’ve seen Troponin blood tests, cardiac MRIs and echo. For example, cardiac injury was associated with a higher risk of death in hospitalized patients. And yet, we have no answers to the questions that matter for clinical practice.
We still don’t know what COVID-19 is doing to the heart or how we should be investigating it and treating it. Last month JAMA Cardiology published a German cohort study of 100 patients recently recovered from COVID-19.
A number of striking problems with the study were noted on Twitter.
