Outcome Measures

Primary Outcomes (1)

  • Detection of death, myocardial infarction , arrhythmia and hospitalization for HF

    Detection of death, myocardial infarction (not related to index procedure) and hospitalization for heart failure or arrhythmia at 6-12 months after revascularization or medical treatment based on CMR viability testing.

    6-12 months after revascularization or medical treatment based on CMR viability testing.

Secondary Outcomes (3)

  • - Quality of life assessment using Kansas Qol questionnaire.

    6-12 months after revascularization or medical treatment based on CMR viability testing.

  • - Improvement of echocardiography measured LVEF at 6-12 months after revascularization.

    6-12 months after revascularization or medical treatment based on CMR viability testing.

  • - Detection of the effect of delayed revascularization after the CMR viability study on the outcome.

    6-12 months after revascularization or medical treatment based on CMR viability testing.

Study Arms (2)

CMR viability study group

Diagnostic Test: CMR Basic CMR data including LV and RV volumes, SWMA reported, EF and wall thinning will be collected. * SWMA from SSFP sequences will be reported and numbered according to the usual (1 normal, 2 hypokinetic, 3 akinetic, 4 dyskinetic, 5 aneurysmal). * Data of viability assessed with LGE imaging with scar measurement using standard deviation method with SD of 4-5 will be used. * AHA 17 segment model will be used as a reference for LV segmentation. * Viability scoring will be calculated for each segment based on the transmurality index, in a semiautomated method, with no scar given 0, 1-25% subendocardial scar given score 1, 25-50% given 2, 50-75% given 3, \>75% as 4. * Wall thinning will be given 0 or 1 score for each segment, with 1 given for \<6 mm thickness.

Sampling MethodNon-Probability Sample
Study Population

Ischemic cardiomyopathy patients

You may qualify if:

  • Patients \>18 years of age, with LVEF\<40%.
  • Patients presenting for viability assessment to Assiut university Heart Hospital, starting from October 2020 till September 2021, will be retrospectively recruited.
  • Patients with a coronary angiography that is amenable for revascularization. The decision and type of revascularization will be determined by the treating physicians.

You may not qualify if:

  • Classic CMR and gadolinium-based dye contraindications including non-MRI compatible implants/foreign bodies (e.g. non-MRI compatible pacemaker, large pieces of shrapnel) and patients with eGFR\<30 ml/min/1.73 m2.
  • Patients with non-ischemic cardiomyopathy confirmed by both CMR and coronary angiography.
