Abstract:
Objective To assess the relationship between Tei index and the clinical symptoms of cardiac dysfunction in aortic stenosis. Methods Ninety-two patients with aortic stenosis [53 males, 39 females; mean age (66?9) years] underwent echocardiographic examination. According to clinical symptoms, patients were classified into two groups: group A without symptom or with mild symptoms (NYHA Ⅰ/Ⅱ, 63 patients), group B with more severe symptoms (NYHA Ⅲ/Ⅳ, 29 patients).Results The common parameters of aortic stenosis severity(aortic valve area, maximal Doppler velocity and transaortic gradient) were not different between the two groups. Left ventricular(LV) mass and LV mass index were higher in group B than in group A [(311?83)g vs (277?70)g, P=~0.044 , and (181?45)g/m2 vs (156?39)g/m2, P=~0.008 , respectively]. The conventional systolic function parameter(ejection fraction) and diastolic function parameters(deceleration time, transmitral inflow velocity E/A ratio) were not significantly different in these two groups. On the contrary, Tei index was significantly higher in group B than in group A (~0.64 ?~0.26 vs ~0.40 ?~0.08 , P
