“…TCM or stress-induced cardiomyopathy was first discovered in Japan in the 1990s and is predominantly seen in elderly women [3,5]. TCM can present like ACS, however, on examination of the coronaries, obstructive disease cannot be demonstrated [7]. In patients who are suspected to have ACS, studies have shown that 1.0-2.2% of cases are related to stress-induced cardiomyopathy [1,8].…”

“…Influenza is known to cause myopericarditis in about 10% of cases, but only a few case reports have reported stress-induced cardiomyopathy triggered by the virus [3-5,9]. Cioni reported an unfortunate case of TCM secondary to influenza which was complicated by cardiac arrest highlighting the potential dangers [7]. Buzon et al reported new stress-induced cardiomyopathy due to the H1N1 subtype of influenza [5].…”

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.
