Exercise alot? Well then this study on a marathon runner will be of interest...

Doctors at the University of Maryland Medical Center had a mystery on their hands. A 51-year-old physician colleague who looked the picture of health—no cardiovascular risks, a marathon runner who had exercised vigorously each day for 30 years—had just flunked a calcium screening scan of his heart.

The researchers conclude that the physician’s intense, long-term exercise regime, coupled with a predisposition toward a type of hypertension, contributed to his cardiovascular disease. "In this particular individual, we think that oxidative stress was an important contributor,"

the patient was given vitamins C and E just before exercise and was tested again for endothelial response. These vitamins are known as antioxidants and may protect cells from free radical damage. This time, the test revealed a partial reversal of the blood vessel constriction after one hour, and normalization after two hours.

"As he took the vitamin C and vitamin E, you could see improvements in his brachial arteries," says Dr. Miller. "We recommended that the patient take these vitamins before he runs."

Isn't "oxidative stress" just another word for marathoning? Running in the city--pollution + increased oxidation = bad news for the CV system.

Predisposition towards a certain type of hypertension: I'd say so, I don't know too many endurance athletes that are even close to sufficient in minerals (too dang much sweating, along with the same needs as the antioxidants he/they are deficient in).
