ATLANTA (Reuters) - A cholesterol-lowering statin drug has for the first time been shown to reverse the build-up of plaque in coronary arteries, which can lead to a heart attack or stroke, researchers said on Monday.
A study of more than 500 patients found that after two years of treatment with a high dose of AstraZeneca Plc's Crestor, plaque volume was reduced by 7 percent to 9 percent.
The drug also lowered levels of LDL, or "bad," cholesterol by more than 53 percent to 60.8 and raised levels of HDL, or "good," cholesterol by nearly 15 percent to an average of 49.
Crestor is considered to be one of the most powerful statin drugs, but it has been dogged by concerns about potential side effects such as muscle damage.
The changes in cholesterol levels seen in the latest study were the largest ever seen in a major trial of statin drugs, said researchers, who presented the results at a meeting of the American College of Cardiology in Atlanta.
