An unusual case of heart failure due to Plasmodium vivax infection with a favorable outcome

Although malaria is one of the oldest types of parasitic infection, we have recently witnessed substantial changes in the outcome of malarial infections. Severe Plasmodium vivax infections have recently become more frequent, and are occasionally associated with fatal outcomes. Cardiac arrhythmia and myocardial failure have also been reported, typically in association with Plasmodium falciparum infections. We report a case of myocarditis and heart failure, due to Plasmodium vivax infection, along with the favorable outcome.
