Table 4
Diagnostic accuracy of dobutamine echocardiography and myocardial contrast echocardiography for prediction of improvement of contractile function at two month follow up
| Sensitivity (%) | Specificity (%) | PPV (%) | NPV (%) | |
|---|---|---|---|---|
| Dobutamine echocardiography | 60 | 90 | 86 | 69 |
| Contrast reflow 75% | 70 | 60 | 64 | 67 |
| Contrast reflow 50% | 100 | 30 | 58 | 100 |
| Contrast collateral flow (+) | 60 | 70 | 64 | 63 |
| Contrast reflow 75% and/or collateral flow | 100 | 60 | 69 | 100 |
| Contrast reflow 75% and collateral flow | 45 | 90 | 75 | 62 |
-
Reflow 75%, 75% of the risk area reperfused with contrast (“strong criterion”).
-
Reflow 50%, 50% of the risk area reperfused with contrast (“weak criterion”).
-
PPV, positive predictive value; NPV, negative predictive value.
