 This led the investigators group to conduct a longitudinal cohort study utilizing pregnancy as a model of increasing cardiac preload and observing the effects on LV trabeculation. During pregnancy, at 28-36 weeks gestation, in increase in LV trabeculation was seen in 25.4, having demonstrated normal myocardium at baseline. Moreover, 7.8 of women fulfilled Chin and Jenni criteria for LVNC. In addition, black women appeared to demonstrate a higher prevalence of increased LV trabeculation as compared with white women 46 vs. 13; p 0.0003.
