Post pulmonary embolism syndrome: a common, underdiagnosed complication that is not well recognised.

A 56-year-old man developed chronic breathlessness which persisted for years after he suffered acute pulmonary embolism (PE) despite all investigations being subsequently normal. This case illustrates a very common complication which occurs in up to half of all patients after an acute PE which has been labelled 'post pulmonary embolism syndrome', yet it is not well recognised and at present there is not much research into the prevention or even possible treatment options for patients who develop these symptoms. © BMJ Publishing Group Limited 2019.
