Data are scarce regarding sex differences among patients with acute myocarditis (AM). Our aim was to define the sex differences in clinical characteristics as well as in-hospital outcomes in a cohort of consecutive patients hospitalized due to AM. We analyzed data of 322 consecutive patients from January 2005 to December 2017 who were hospitalized with the diagnosis of AM. Eighty-four percent (N = 272) of the patients were males. When compared to females, male patients were younger (36 ± 14 vs 45 ± 17 years, p <0.001), more likely to present with ST segment elevation (75% vs 44%. p <0.001) as well as PR depression upon ECG, and have higher admission troponin levels (7.6 ± 11 vs 2.3 ± 4 µg/L, p <0.001). Moreover, males were more likely to have late gadolinium enhancement upon cardiac magnetic resonance. While male patients were more likely to have ventricular arrhythmias during hospitalization (7% vs 0%, p = 0.05), there were no differences in the incidence of in-hospital mortality or the need for escalation therapy during hospitalization between both groups. There were no episodes of mortality upon all patients among a follow-up of 1 year. In conclusion, male patients, which constitute the majority of patients admitted with AM were younger, more likely to present with ST elevation, had higher troponin levels at admission, and had a higher rate of ventricular arrhythmias compared to females. There were no differences in post-discharge mortality rates between males and females.
