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.
