Abstract/OtherAbstract:
OBJECTIVE: To identify early echocardiographic abnormalities at the time of diagnosis of polymyositis (PM) and dermatomyositis (DM) and follow the echocardiographic findings during the first 3 months of therapy.
METHODS: We included 30 PM/DM patients (23/7) with a mean age of 42.3 ± 1.6 years and without cardiovascular symptoms. Age-matched healthy patients served as controls. Clinical characteristics were recorded. Traditional echocardiography and tissue Doppler imaging (TDI) were performed to measure systolic [ejection fraction, right ventricular fractional area change (RV FAC), lateral and tricuspid annulus s velocities] and diastolic echocardiographic variables (mitral inflow velocities: E, A; deceleration time: DT; lateral and tricuspid annulus e', a' velocities, lateral E/e').
RESULTS: The left and right ventricular systolic dysfunction detected by TDI at the time of the PM/DM diagnosis improved, and characteristic values at the end of the followup period were comparable to those of the controls (lateral s: 10.6 ± 0.2, 8.7 ± 0.4, 9.6 ± 0.3, 11.3 ± 0.2 cm/s; RV FAC: 45.2 ± 2.3, 36.9 ± 1.5, 42.2 ± 1.3, 46.9 ± 1.2%; tricuspid s: 13.3 ± 0.2, 9.5 ± 0.4, 10.3 ± 0.3, 11.6 ± 0.5 cm/s; control, 0, 1, and 3 mos, respectively). Measurements indicated the development of diastolic dysfunction at 3 mos (E/A: 1.4 ± 0.1, 1.29 ± 0.05, 1.03 ± 0.05, 0.92 ± 0.05; DT: 148.6 ± 3.6, 157.3 ± 5.7, 168.3 ± 6.0, 184.3 ± 6.2 ms; lateral e': 12.8 ± 0.3, 12.1 ± 0.5, 10.2 ± 0.6, 10.8 ± 0.8 cm/s; E/e': 5.6 ± 0.1, 5.0 ± 0.22, 6.92 ± 0.46, 7.64 ± 0.47; control, 0, 1, and 3 mos, respectively).
CONCLUSION: TDI is a useful method to detect early cardiac abnormalities complementing the conventional echocardiographic measurements. LV and RV systolic dysfunction found in the acute phase significantly improved during the first 3 months of therapy; however, deterioration of diastolic dysfunction was also observed.
