Do "antioxidants" contribute to heart health?

There has been a great deal of interest in antioxidants and their potential effect in heart disease since we discovered that LDL, the bad cholesterol, is actually oxidized as it is taken into artery walls. That oxidation is an important facet of it becoming part of the atherosclerotic plaque, the cholesterol plaque, hardening of the arteries. It would make sense then that antioxidants would deoxidize something and that might be of benefit. Unfortunately, antioxidants haven't been shown to have an effect in reducing coronary disease, even when they are used in patients who have demonstrable coronary disease. So, they don't seem to prevent another episode and in some circumstances they actually can have a harmful effect.
