Cholesterol-lowering drugs
The main types used are statins. Statins work by inhibiting an enzyme involved in the production of LDL cholesterol. Results from studies using 90 000 participants showed that statins quickly reduce the risk of heart disease and stroke. Studies have shown that there is a linear relationship between absolute reductions in LDL cholesterol and reductions in the incidence of major vascular events such as heart attack and stroke.
Some studies have raised conerns that the use of statins may increase the risk of death by other non-vascular causes, and also increase the risk of developing particular cancers. Research was carried out and no evidence that lowering LDL cholesterol by 1 nmol/1 with 5 years of statin treatment increased the risk of deaths by other non-vascular causes or of developing particular cancers.
