Do specific heparin preparations interfere with the simultaneous measurement of ionized magnesium and ionized calcium?

We found a significant association between coronary atherosclerosis and a molecular variant of the angiotensin gene. The results suggested that the molecular variant of the angiotensinogen gene could be a new risk factor for coronary atherosclerosis.
