Table 3 Correlation between peak CK-MB and scar size, left ventricular volumes, ejection fraction (EF) and wall motion abnormality index (WMAi) at recovery and chronic phase after myocardial infarction

From: Peak CK-MB has a strong association with chronic scar size and wall motion abnormalities after revascularized non-transmural myocardial infarction – a prospective CMR study

  Recovery phase CMR
(correlation to peak CK-MB)
Chronic phase CMR
(correlation to peak CK-MB)
  All (n = 41) Non-transmural MI (n = 33) All (n = 41) Non-transmural MI (n = 33)
Scar size, % 0.80 (p < 0.001) 0.74 (p < 0.001) 0.83 (p < 0.001) 0.78 (p < 0.001)
EDV, ml/m2 0.49 (p = 0.001) 0.47 (p = 0.006) 0.31 (p = 0.050) 0.317 (p = 0.072)
