We declare no competing interests. Risk of acute myocardial infarction and ischaemic stroke following COVID-19 in Sweden: a self-controlled case series and matched cohort studyOur findings suggest that COVID-19 is a risk factor for acute myocardial infarction and ischaemic stroke. This indicates that acute myocardial infarction and ischaemic stroke represent a part of the clinical picture of COVID-19, and highlights the need for vaccination against COVID-19. Full-Text PDF COVID-19 and myocardial infarction – Authors' replyWe thank Daniel Caldeira and Fausto Pinto for their comments regarding our study1 focusing on COVID-19 and myocardial infarction. We did acknowledge the difficulties in distinguishing between different types of myocardial injuries in the discussion. The International Classification of Diseases versions 9 and 10 unfortunately do not distinguish between ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), which is a limitation of our study.
