Key result
Right ventricular infarction was associated with a significantly increased right ventricular myocardial performance index compared to inferior left ventricular infarction (0.85 vs 0.26; P<0.01).
Why the study?
Does the Doppler echocardiographic right ventricular myocardial performance index accurately identify right ventricular dysfunction in patients with right ventricular infarction compared to those with inferior left ventricular infarction?

Does the Doppler echocardiographic right ventricular myocardial performance index accurately identify right ventricular dysfunction in patients with right ventricular infarction compared to those with inferior left ventricular infarction?
Absolute Event Rate: 0.85% vs 0.26%
p-value: p=< 0.01
The right ventricular myocardial performance index is a reliable echocardiographic parameter for diagnosing right ventricular infarction and assessing right ventricular performance.
Mattioli et al. (2000) conducted an observational in Right ventricular infarction (n=120). Right ventricular infarction vs. Inferior left ventricular infarction without right ventricular involvement was evaluated on Myocardial performance index (p=< 0.01). Right ventricular infarction was associated with a significantly increased right ventricular myocardial performance index compared to inferior left ventricular infarction (0.85 vs 0.26; P<0.01).
