Healthy adults who have their LDL-C or & # 39; bad cholesterol & # 39; not under control, are more likely to die prematurely from cardiovascular disease than peers with lower cholesterol levels, suggests a study from the US.

Researchers examined data on 36,375 adults without a history of cardiovascular disease or diabetes and a low 10-year risk for events such as heart attacks or strokes.

In comparison with people with a very low LDL-C content of less than 100 milligrams per deciliter (mg / dL) of blood, individuals with LDL-C levels ranging from 100 to 159 mg / dL had a 30 to 40% higher risk. on death from cardiovascular diseases. With LDL-C values ​​from 160 mg / dL to 189 mg / DL, people had a 90% higher risk of death from cardiovascular causes. LDL-C values ​​of at least 190 mg / DL had a 70% greater risk.
