Strain Rate Imaging for Assessment of Regional Myocardial Function
Why the study?
Does strain rate imaging improve the assessment of regional myocardial function compared to tissue Doppler imaging in patients with a small, discrete myocardial infarction?

10 patients with severely symptomatic septal hypertrophy undergoing basal septal ablation via intracoronary…

Implication
Strain rate may better detect regional dysfunction than tissue velocities in small infarcts; leaves open clinical adoption pending prospective validation.
Structured PICO
Does strain rate imaging improve the assessment of regional myocardial function compared to tissue Doppler imaging in patients with a small, discrete myocardial infarction?
P
Population
10 patients with severely symptomatic septal hypertrophy undergoing basal septal ablation via intracoronary alcohol injection
I
Intervention
Strain rate imaging (SRI)
C
Comparator
Tissue Doppler imaging (TDI)
O
Outcome
Regional myocardial function assessment (peak systolic strain rate and peak systolic tissue velocities) pre- and post-ablation, and between infarct and noninfarct areassurrogate
Strain rate imaging accurately depicts changes in regional myocardial function in small, discrete infarcts where global function remains unchanged, outperforming tissue Doppler imaging.
