CBS News reports a study published in the Annals of Internal Medicine which found a new class of drugs called PCSK9 antibodies to have a significant effect on reducing heart attacks and mortality from high cholesterol. One in six adults in the US lives with high cholesterol and have trouble getting control over it. These new drugs target PCSK9, a cholesterol-regulating protein, and lower LDL levels by 60 percent. Currently, high cholesterol is typically treated with statins which work for most people. However, some patients are unable to tolerate the side effects ranging from headaches to diarrhea, and some have such high cholesterol that statins alone are not enough, possibly making these new drugs the perfect accompaniment or alternative to statins.
