Group 1 – psoriasis patients, group 2 – control group, LVEF – left ventricular ejection fraction, DT – deceleration time, IVRT – isovolumetric relaxation time, LA – left atrium, LAV max – LA maximum volume, LAV min – LA minimum volume, LAV reservoir – LAVmax. – LAVmin, LAGLSs – global peak systolic LA myocardium strain during left ventricular systole, LAGLSRs – global peak systolic positive LA myocardial strain rate during left ventricular systole, LAGLSRe – global peak negative LA myocardial strain rate during early ventricular diastole, LAGLSRa – global peak negative LA myocardial strain rate, TACT – total atrial conduction time, PWD – P-wave duration difference; p < 0.05 indicates a significant difference.
