INTRODUCTION: Biological sex has a paramount influence on the pathophysiology of diseases, and thus on clinical presentation. In this study, we provide a comprehensive analysis of sex-specific differences in patients with myocarditis.
MATERIALS AND METHODS: Patients with myocarditis who were admitted to our study center in the time-period of 2009-2019 were retrospectively enrolled in this study. Clinical data, laboratory parameters, and measurements from transthoracic echocardiography were extracted from hospital records. Follow-up was acquired for 2 years after admission.
RESULTS: Two hundred twenty-four patients with myocarditis were enrolled in this study. Of these, 78% were men and 22% women. Female patients were older (median 50 years vs. 35 years, p < 0.0001), had a higher prevalence of respiratory tract infections, and had less frequently ST-segment elevations on electrocardiogram (ECG) (28% vs. 59%, p = 0.003). Furthermore, C-reactive protein was lower in women (median 0.60 mg/dL vs. 3.90 mg/dL, p < 0.0001), but showed a less pronounced decrease within 3 days when compared to men (fold-change 1.00 vs. 0.80, p = 0.002). Cardiac magnetic resonance imaging was conducted less often in women, whereas time to coronary angiography was significantly longer. We found no difference in left ventricular systolic function or all-cause-mortality between the 2 sexes.
CONCLUSION: We observed sex-specific differences in laboratory parameters, abnormalities on ECG, and diagnostic procedures conducted in patients with myocarditis. Understanding these differences, both at the cellular level and in regard to the clinical presentation of patients, could be helpful in the diagnosis and treatment of this disease, and could further expand our understanding of its pathophysiology.
