The myocardial performance index (MPI) is used for global systolic-diastolic left ventricular function and prognosis assessment in patients with heart disease, allowing assessment of the patient‘s current condition and disease development follow-up. The classic method of calculation is pulsed Doppler echocardiography. The aim of the study was to evaluate the correlation of myocardial performance index with established left ventricular systolic and diastolic function indices and to determine cut-off values of the myocardial performance index in M-mode color tissue Doppler echocardiography through the aortic and mitral valves predicting abnormal myocardial performance index by pulsed Doppler echocardiography. One hundred and fi ve subjects were studied, including 30 healthy controls, 45 hypertensive patients, and 30 patients with CHD. MPI was calculated using pulsed Doppler (MPIPW) and M-mode color tissue Doppler echocardiography through the aortic (MPIAO1 and MPIAO2) and mitral (MPIMV) valves. In all patients, the myocardial performance index showed a low to moderatenegative correlation with the left ventricular ejection fraction, and the correlation with the diastolic function indices was moderate to high. In healthy persons, the correlations were not signifi cant in almost all comparisons. The MPIAO1, MPIAO2,and MPIMV values predicting abnormal MPI by pulsed Doppler (MPIPW ≥ 0.50) are MPIAO1 ≥ 0.578, MPIAO2 ≥ 0.446, and MPIMV ≥ 0.552. The cut-off values of MPI by M-mode color tissue Doppler echocardiography through the aortic and mitral valve obtained can be used for global left ventricular function assessment in patients with heart disease. Further studies, on a larger number of patients, are necessary to estimate the predictive value of the parameters established.

In this study, left and right ventricular functions were examined echocardiographically in 22 patients with scleroderma and 22 healthy volunteers. Conventional and tissue Doppler echocardiography and myocardial performance indexes were used as measures of right and left ventricular global functions. Mitral early diastolic E wave deceleration time, isovolumetric contraction time and left ventricular myocardial performance index and peak tricuspid A wave velocity were significantly higher in the scleroderma group compared with the control group. Mitral and tricuspid E/A ratios were significantly lower in patients with scleroderma. In addition, mitral annular and tricuspid annular isovolumetric relaxation times and the tricuspid E/E' ratio were significantly increased in scleroderma patients compared with the control group. In conclusion, in scleroderma patients the global left ventricular functions were depressed and diastolic function abnormalities were seen in both right and left ventricles. In addition, longitudinal muscle functions of the ventricles were depressed in scleroderma patients, as shown by tissue Doppler imaging parameters.

Abstract Objective This study aims to compare completion rates and reproducibility of myocardial performance index (MPI) using conventional spectral Doppler versus tissue Doppler in an unselected high-risk third trimester population. Study Design This was a prospective cross-sectional study of high-risk pregnancies at ≥28 + 0 weeks’ gestation. Conventional spectral and tissue Doppler MPI of the left ventricle (LV) and right ventricle (RV) was attempted on all patients. Results Seventy-nine pregnancies were evaluated. LV tissue Doppler MPI was completed more frequently than LV conventional spectral Doppler MPI (63/79, 79.7% vs. 45/79, 55.7%), p-value <0.01. RV tissue Doppler MPI was completed more frequently than RV conventional spectral Doppler MPI (68/79, 86% vs. 42/79, 53.2%), p-value <0.01. In obese subjects (n = 50) LV tissue Doppler MPI was completed more frequently than LV conventional spectral Doppler MPI (37/50, 74% vs. 26/50, 52%), p-value <0.01. RV tissue Doppler MPI was completed more frequently than RV conventional spectral Doppler MPI (40/50, 80% vs. 25/50, 50%), p-value <0.01. intraclass correlation coefficient for all modalities ranged between 0.73 and 0.93, except for LV conventional spectral Doppler intraobserver variability which was 0.22. Conclusion Tissue Doppler had statistically higher completion rates than conventional spectral Doppler, including the obese subgroup, with evidence of strong reproducibility in the third trimester.
