Table 4 Comparison of regional contractility by CMR before and after successful CTO recanalization

From: Benefits of chronic total coronary occlusion percutaneous intervention in patients with heart failure and reduced ejection fraction: insights from a cardiovascular magnetic resonance study

  Successful CTO-PCI n = 29
Regional contractility Pre-PCI Post-PCI Difference p
Global Normal or mild-moderate hypokinesia 8.5 ± 4.5 11.2 ± 3.5 2.7 0.001
Severe hypokinesia/akinesia/dyskinesia 8.3 ± 4.6 5.7 ± 3.5 −2.6 0.002
CTO- dependent segments Normal or mild-moderate hypokinesia 2.9 ± 2.2 3.6 ± 2 0.7 0.011
Severe hypokinesia/akinesia/dyskinesia 3.9 ± 1.8 3.3 ± 1.3 −0.62 0.029
  1. Values are given as mean ± standard deviation. CTO indicates chronic total occlusion; PCI percutaneous coronary intervention
