Moderate agreement indicates MPI and TDI-MPI are not interchangeable; leaves open need for method-specific validation in post-MI cohorts.
Does tissue Doppler imaging agree with conventional pulsed wave Doppler in the measurement of myocardial performance index in patients with prior MI and healthy subjects?
The agreement between pulsed wave Doppler and tissue Doppler imaging for measuring myocardial performance index is only moderate, suggesting the two methods are not directly interchangeable.
