Key result
Critical coronary stenosis was associated with a significantly higher index of myocardial performance compared to no critical stenosis (0.53 vs 0.45; P<0.001).
Why the study?
Does the index of myocardial performance (MPI) differ between patients with and without critical coronary artery disease and correlate with invasive measurements of left ventricular function?

MPI elevation may flag critical CAD; hypothesis-generating and requires prospective validation.
Observational (n=82)
Does the index of myocardial performance (MPI) differ between patients with and without critical coronary artery disease and correlate with invasive measurements of left ventricular function?
Absolute Event Rate: 0.53% vs 0.45%
p-value: p=<0.001
Dağdelen et al. (2002) conducted an observational in Critical coronary artery disease (n=82). Critical coronary stenosis (> 70%) vs. No critical coronary stenosis was evaluated on Index of myocardial performance (MPI) (p=<0.001). Critical coronary stenosis was associated with a significantly higher index of myocardial performance compared to no critical stenosis (0.53 vs 0.45; P<0.001).
