A multiple sclerosis drug may work double duty. It has been shown in a lab study to prevent and even reverse one of the leading causes of heart attack.

Now that the U.S. Centers for Disease Control and Prevention have found a way to measure blood levels of trans-fatty acids in the blood, they've discovered some good news.

Men may be at an added genetic risk of developing heart disease. That's because the Y chromosome, a portion of DNA that only men have, appears to play a role in inheriting coronary artery disease.

About 90 percent of U.S. adults are incorporating too much sodium into their diets. However it doesn't appear the dinner-side salt shaker is at fault.

Heart health can be improved with lifestyle changes - weight loss, exercise and a healthy diet. It may be that these changes also reduce a man's risk of prostate cancer.

Taking both clopidogrel ( Plavix ) and aspirin together does not appear to cut the risk of recurrent deep brain strokes. Research suggests it also increases the risk of bleeding events or dying.

Technology and procedures to treat unruptured brain aneurysms, which can lead to hemorrhagic stroke caused by cranial bleeding, have improved significantly in the last decade.

Some patients may better respond to clot busting drugs immediately after the onset of stroke symptoms. The challenge is figuring out which patients are most likely to benefit.

In the late 1990s there was a striking disparity among the number of black children who died of stroke as compared to white children. Black children were 74 percent more likely to die of a stroke, because of the higher prevalence of sickle cell anemia in that population.

Certain factors have been traditionally used for predicting the risk for stroke, such as high cholesterol. But these factors may not be very accurate in predicting stroke risk for postmenopausal women.
