SAT0173 Assessment of Left Ventricular Dyssynchrony in Patients with Familial Mediterranean Fever

Background Familial Mediterranean fever (FMF) is a disease characterized by recurrent and sustained increased inflammatory activity. Various clinical and subclinical cardiovascular involvements have been reported in FMF patients. However, there is considerable lack of evidence regarding contraction synchrony in FMF. Objectives We aimed to study the left ventricular contraction synchrony in FMF patients with narrow QRS and normal EF. Methods Seventy patients with FMF and 35 age- and sex- matched control subjects were included the study. Left ventricular dyssynchrony was investigated by color coded tissue Doppler imaging. Results In the FMF group, the mean high-sensitive C-reactive protein (hs-CRP) values were significantly higher, compared with the controls (p 34.4 ms) were higher in the FMF group than the control group (34.2±6.9 vs. 24.7±5.8; p Conclusions We found out that in FMF patients with normal EF and narrow QRS, left ventricular systolic dyssynchrony is an early manifestation of heart involvement and may be coexisted with by diastolic dysfunction.
