According to a study from the University of Iowa, cholesterol-lowering drugs may save lives when used in people with higher levels of LDL cholesterol, or “bad” cholesterol. Statins are the safest drugs for reducing the risk of heart attacks, strokes, and death in a wide range of patients. Patients with higher LDL cholesterol levels are likely to experience greater health benefits from taking statins and some of the newer cholesterol drugs.
The study analyzed 34 previous studies that involved more than 270,000 participants. The analysis found that statins were more likely to reduce the risk of death when LDL cholesterol levels were 100 milligrams per deciliter (mg/dl) or greater, whether or not they were used with other LDL-lowering drugs. The study found the lives of an additional 4.3 in 1,000 people were saved every year when treated with LDL cholesterol lowering therapy.
The greatest benefit and the greatest reduction in death rates came to those with the highest levels of LDL cholesterol, LDL cholesterol causes fat and plaque to build up in arteries, increasing the risk for heart attacks and strokes. Levels below 100 mg/dl are considered optimal, as people with that reading are less likely to develop cholesterol plaques as they age. Readings above 100 mg/dl are considered unhealthy.
People with excess LDL can reduce their levels through an improved diet, increased exercise, and by taking medications such as statins. People who have cardiovascular disease or genetic causes of high cholesterol also may benefit from adding other LDL-lowering drugs to statin therapy. The study shows that LDL-lowering drugs can be effective for preventing heart attacks and stroke in people with risk factors even when LDL cholesterol levels are low, but even more heart attacks and death are prevented when people have LDL levels above 100 mg/dl.
