WASHINGTON - Excess iron in the body can harm the endothelium, or inner lining of blood vessels, boosting a person's odds of developing hardening of the arteries and heart attack, a Japanese study concludes.

According to study lead investigator Dr. Hidehiro Matsuoka of Kurume Medical School, high levels of iron appear to impede the action of nitric oxide, a chemical released by the endothelium, which aids in keeping blood vessels relaxed. A number of studies have shown that iron is a risk factor for arteriosclerosis, or hardening of the arteries.

Matsuoka stressed that oral iron supplements are generally safe, because absorption at those dosage levels is "quite limited."

Nevertheless, consuming high amounts of iron over the long term may increase iron levels in the body, he cautioned. Matsuoka said people should watch their intake of iron the same way they watch cholesterol, and get regularly tested for high iron levels if they are over 40 and have other risk factors for heart disease, such as high blood pressure or diabetes.

In one phase of the study, scientists injected 10 healthy volunteers with high doses of iron (0.7 milligrams per kilogram body weight) and used ultrasound imaging to observe arterial wall functioning.

The excess iron raised levels of malondialdehyde, a chemical marker for oxidation, and inhibited normal endothelial function. The development of rust on metals is the result of oxidation.

The researchers also monitored the effects of lowering iron blood levels in 10 cigarette smokers and found that this caused endothelial function to return to normal.

Understanding the effects of iron removal in smokers is important because, among risk factors for heart disease, smoking is one of the strongest causes of oxidation.

The study also could help to explain why premenopausal women have less heart disease, since iron is removed from the body in menstruation. Previous studies have pointed to the protective effects of estrogen in women of childbearing age.

Iron overload can occur when iron is given intravenously to treat certain types of anemia and chronic kidney failure, Matsuoka noted. He urged that whenever possible, intravenous iron administration "should be avoided" to prevent future heart attacks and stroke.

Matsuoka presented his findings at a meeting of the American Heart Association's Council for High Blood Pressure Research.
