In a landmark study, researchers from the University of Southern
California School of Medicine tested and monitored 162 men with heart
disease who had previously had a bypass.
The investigators first took arterial x-rays of the men's diseased blood vessels to gauge the extent of damage. Then they gave half the men a low-fat diet plus two cholesterol-lowering drugs; the other half got jut the low-fat diet. After two years, the researchers again took x-rays and compared them with the earlier ones.
The result? In 16 percent of the diet-plus-drugs group, the amount of heart disease was visibly less. In 2.4 percent of the diet-without-drugs group, the amount of heart disease was also visibly less. Clearly, in some cases heart disease can be reversed.
