Hos dem som har kardiella symtom under pågående infektion, såsom bröstsmärta, svår andnöd eller palpitationer, bör troponiner och CRP kontrolleras, speciellt om det rör sig om idrottare på hög nivå. Beakta att troponiner normalt kan vara lindrigt förhöjda 48 timmar efter träning.

Om klinisk misstanke om myokardit föreligger rekommenderas testning inkluderande vilo-EKG, rytmregistrering, ekokardiografi och MR. I övrigt handläggning enligt ovan.

Alla elitidrottare som ska återgå i tävlingsidrott efter genomgången covid-19 ska bedömas av sin lagläkare (alternativt annan kollega). Denna första bedömning innehåller en noggrann hjärtanamnes och undersökning (Figur 1).

There have been rare cases of myocarditis (inflammation of the heart muscle) following the Moderna and the Pfizer vaccine in the UK, and it has been listed as a very rare side effect.

Myocarditis has also been listed as a rare possible side effect of the Novavax vaccine, after a very small number of cases were reported during clinical trials.

For every million doses given of the monovalent Pfizer/BioNTech vaccine, there have been 10 reports of myocarditis and 6 reports of pericarditis, according to the Medicines and Healthcare products Regulatory Agency (as of 23 November 2022). There have been 14 reports of myocarditis and 8 reports of pericarditis for every million doses given of the monovalent Moderna vaccine over the same period.

While reports of myocarditis following any Covid-19 vaccine are rare, cases are more common in young males aged 18 to 29 years following the second dose. Most people who have been affected have experienced a mild illness and recovered without medical treatment.

Myocarditis can cause heart scarring that can be detected with cardiac MRI – there is a small chance of scarring causing a life-threatening arrhythmia in the future, and therefore people who are affected are likely to be offered long-term follow-up and monitoring.

Research has found that Covid-19 itself is much more likely to cause myocarditis than the vaccine is, and people who are vaccinated have a much lower risk of getting other serious complications caused by Covid-19.
