  • PURPOSE: The aim of the study was to assess the presence and spectrum of cardiac abnormalities identified by cardiac magnetic resonance (CMR) in women with hypereosinophilic syndrome (HES) of undefined etiology, who present with normal electrocardiography (ECG) and transthoracic echocardiography (TTE) and no history of heart disease. METHODS: Ten women (mean age, 48 ± 14 years) with HES of undefined etiology, normal ECG and TTE, and no history of heart disease underwent CMR. RESULTS: CMR showed cardiac abnormalities in 6 subjects. Five patients had nonischemic late gadolinium enhancement (LGE) lesions within the left ventricular (LV) myocardium, and 3 patients demonstrated CMR evidence of myocardial inflammation. The LV ejection fraction was 68.5 ± 5.7%, and the end-diastolic volume index was 62.7 ± 14.7 mL/m(2). The maximum measured blood eosinophil count correlated with LVLGE volume (r = 0.80, P = 0.006) and was 11374 ± 6242 cells/μL and 4114 ± 2972 cells/μL (P = 0.047) in patients with and without LGE lesions, respectively. The actual blood eosinophil count in subjects with and without CMR evidence of myocarditis was 1058 ± 520 cells/μL and 354 ± 377 cells/μL (P = 0.04), respectively. CONCLUSIONS: Despite normal ECG, TTE, and absence of history of heart disease, women with HES of unknown etiology frequently demonstrate cardiac abnormalities on CMR, the presence and extent of which are related to blood eosinophil count.
