    Abstract:
    PURPOSE: Although cardiac manifestation of Behçet disease (BD) has been described in sporadic reports, its timely diagnosis remains difficult. The objective of this study was to describe early cardiac manifestations of BD. We also performed a comprehensive classification of systemic BD activity and compared their cardiac manifestations. METHODS: A prospective screening using speckle tracking echocardiography was performed in 85 patients with BD who had no history of heart disease. After excluding subjects with left ventricular (LV) ejection fraction (LVEF) <50% (n = 1), atrial fibrillation (n = 2), or inadequate echocardiographic images (n = 1), we analyzed their clinical and echocardiographic parameters including LV global longitudinal strains (GLS) and compared them with those of an age- and gender-matched control group (n = 145). Systemic BD activity was classified as minimal (Group A), controlled (Group B), and active (Group C). RESULTS: In 81 study patients (59 females, age of 51 ± 11 years), echocardiography revealed a mean LVEF of 64 ± 5% without any significant valvular dysfunction or aortic aneurysm. Although there was no difference in LVEF between the control group and the patient group, the patient group showed significant reduction in GLS (-17.1 ± 2.9% vs -20.8 ± 2.2%, P < .001). Groups A (n = 21, 26%), B (n = 47, 58%), and C (n = 13, 58%) consistently showed reduction in GLS compared with the control group. However, there was no significant difference in cardiac manifestations among these groups according to systemic disease activity. CONCLUSION: Patients with BD present intrinsic LV dysfunction despite no apparent abnormality on routine echocardiography. However, their cardiac manifestations are not proportional to systemic BD activity.
