VEGFA and familial dilated cardiomyopathy: While no correlation between ALDOA and VEGF-A was observed in this cohort, it was noted that VEGF-A was significantly up-regulated in oHCM, compared with DCM and ISCM, suggesting that de-regulation of the angiogenesis pathway may also be a key point of difference between oHCM and other heart failure aetiologies.
