INFLUENZA INFECTION AS TRIGGER FOR ACUTE MYOCARDIAL INFARCTION AND STROKE

Abstract

Influenza affects millions of patients every year. The manifestations vary from mild respiratory symptoms to severe pulmonary and extra-pulmonary complications and even death. Recent scientific evidence has been accumulating that influenza infection can trigger acute myocardial infarction and stroke. Both diseases are the leading causes of death worldwide, and the recognition of the risk factors is crucial for adequate prevention. This article reviews the pathogenetic links between influenza and the development of myocardial infarction and stroke. It presents the incidence, timing and outcome of these acute cardiovascular events after influenza infection and the role of vaccination for their prevention. The aim of the review is to focus the attention of medical practitioners on the association between influenza and cardiovascular events in order to improve the prevention and management of high-riskpatients.
