There diagnostic criteria were as follows: (1) >3 prominent trabecular formations along the left ventricular endocardial border, which are visible in end-diastole, distinct from papillary muscles, false tendons, or aberrant bands, (2) trabeculations move synchronously with the compacted myocardium, (3) trabeculations form the noncompacted part of the two-layer myocardial structure, best visible at endsystole, and (4) perfusion of the intertrabecular spaces from the ventricular cavity is present at end-diastole on color-Doppler echocardiography or contrast echocardiography.

* A hypocalcaemia-induced acute coronary syndrome is most likely a function of the myocardium being perfused primarily during diastole, with partial vasospasm limiting the diastolic flow during times of increased cardiac output or energy requirements.
The researchers found that in patients with diabetes, increasing magnitude of stress myocardial perfusion abnormality correlated with an increased risk for cardiac death for severely abnormal myocardium versus normal myocardium (hazard ratio, 7.2) after adjustment for established clinical predictors.
