Table 4 Measures of TDI-MPI and PWD-MPI for the diagnosis of diastolic dysfunction

From: Clinical value of myocardial performance index in patients with isolated diastolic dysfunction

  TDI-MPI (Cut-off point > 0.42) PWD-MPI (Cut-off point > 0.40) P
Accuracy (%; 95% CI) 67 (58 to 76) 66 (57 to 75) 0.91
Sensitivity (%; 95% CI) 74 (60 to 86) 64 (50 to 76) 0.37
Specificity (%; 95% CI) 61 (46 to 74) 69 (55 to 80) 0.53
PPV (%; 95% CI) 64 (50 to 75) 65 (51 to 77) 0.91
NPV (%; 95% CI) 72 (57 to 83) 67 (54 to 78) 0.75
(+) LLR (95% CI) 1.90 (1.30 to 2.8) 2.0 (1.3 to 3.2)  
(−) LLR (95% CI) 0.42 (0.25 to 0.72) 0.53 (0.35 to 0.80)  
  1. MPI myocardial performance index, PPV positive predictive value, NPV negative predictive value; (+) LLR positive likelihood ratio; (−)LLR negative likelihood ratio
