[h=1]Stressing Out from the Flu: A Case of Influenza A-associated Transient Cardiomyopathy.[/h] Faircloth EL[SUP]1[/SUP], Memon S[SUP]2[/SUP].

[h=3]Abstract[/h] Influenza infections are prevalent and have a large impact on our health system. They are associated with multiorgan complications that can have significant morbidity and mortality. Although influenza is a known etiology of myopericarditis, only a few case reports have documented influenza as a cause of takotsubo cardiomyopathy or stress-induced cardiomyopathy. We present a patient who developed a new left bundle branch block with positive cardiac markers, nonobstructive coronary arteries and a new cardiomyopathy that reversed within 48 hours of diagnosis of influenza A infection. This case highlights a rarer cardiovascular complication of influenza; one that would dictate medication changes, require close follow-up, and have a possibility of recurring.
