dc.description.abstractThe goal of this study was to evaluate the preejection time (PEP)-derived myocardial performance index (MPI) in hypertensive (HT) patients with sinus rhythm and its relationship to the classic Tei index. One hundred five patients were enrolled in the study (65 HT and 40 control subjects). The mean age of all patients was 50.5 +/- 15 years and 60% were female. Echocardiography was performed on all patients. MPI was measured with the classic Tei method (MPI-Tei index) and the PEP-derived MPI method by using tissue Doppler echocardiography. Although the MPI-Tei index is defined as the ratio of isovolumetric contraction time (IVCT) along with isovolumetric relaxation time (IVRT) to ejection time (ET), PEP-derived MPI is defined as the ratio of PEP and IVRT to ET. We compared echocardiographic data between the HT group and the control group. MPI-Tei index and the PEP-derived MPI values were higher in the HT group compared with controls (0.52 +/- 0.10 vs 0.39 +/- 0.07, P < 0.001, and 0.51 +/- 0.09 vs 0.39 +/- 0.07). PEP-derived MPI was strongly correlated with the MPI-Tei index (r = 0.945, P < 0.001). Our study determined that the PEP-derived MPI might be used in the evaluation of left ventricular function in patients with HT, similar to the classic MPI-Tei index.en_US
