Key result
M-mode color tissue Doppler accurately predicts abnormal pulsed Doppler MPI with ~0.91 AUC.
Why the study?
The myocardial performance index is used for global left ventricular function assessment, but cut-off values for M-mode color tissue Doppler echocardiography predicting abnormal MPI by pulsed Doppler were not established.
Does M-mode color tissue Doppler echocardiography accurately predict abnormal myocardial performance index compared to pulsed Doppler echocardiography in patients with heart disease and healthy controls?

Does M-mode color tissue Doppler echocardiography accurately predict abnormal myocardial performance index compared to pulsed Doppler echocardiography in patients with heart disease and healthy controls?
Effect estimate: AUC 0.906
M-mode color tissue Doppler echocardiography provides reliable cut-off values for assessing global left ventricular function that correlate well with standard pulsed Doppler measurements.
Иванов et al. (2020) conducted a cross-sectional in Hypertension and Coronary Heart Disease (n=105). M-mode color tissue Doppler echocardiography vs. Pulsed Doppler echocardiography was evaluated on Prediction of abnormal myocardial performance index (MPI ≥ 0.50) by pulsed Doppler using MPI_AO1 (AUC 0.906). M-mode color tissue Doppler echocardiography cut-off values of MPI_AO1 ≥ 0.578, MPI_AO2 ≥ 0.446, and MPI_MV ≥ 0.552 accurately predicted abnormal myocardial performance index by pulsed Doppler.
