2001 DEC 13 - (NewsRx.com & NewsRx.net) -- Study findings reported at the American Heart Association meeting, November 2001, suggest that the number and size of lipoproteins in the body can predict an individual's risk of heart attack.
Although lipoproteins were once difficult and costly to measure, nuclear magnetic resonance (NMR) technology now makes an analysis of lipoprotein size and number a relatively simple task - to analyze a blood sample.
"The results are particularly significant in predicting a woman's risk of heart attack," explained Lewis Kuller, MD, professor and chair, department of epidemiology, University of Pittsburgh Graduate School of Public Health, Pennsylvania. "That is strikingly important when you consider that heart disease is the number one killer of women in this country and almost 60% of the people who die of a heart attack, die suddenly outside of a hospital. The higher the number of small low-density lipoprotein (LDL) particles, the greater the woman's chances of a heart attack.
"In fact, we found that heart attack risk was as much as 2.45 times more likely for women in the study who had the largest number of small LDL particles compared with women who had the lowest number of small LDL particles," he continued.
By assessing this new marker, the researchers say that physicians may be in a much ...
