Changing chemistry helps explain estrogen threat to the heart

... isn't made in an appreciable form. Now it makes a compound called superoxide. It's an oxidant, and oxidation is bad in general. It causes a lot of cellular damage. But what we also have found is that now, instead of causing relaxation, it causes constriction. So you completely flip-flop the response here. "...
