The so-called LDL hypothesis is the concept that excess low-density lipoprotein (LDL) cholesterol is a causal factor in the development of atherosclerotic vascular disease. By extension, this hypothesis also assumes that reducing LDL cholesterol levels, regardless of the means, should produce a corresponding reduction in cardiovascular events. Considerable evidence supports the LDL hypothesis, including animal studies and epidemiologic studies involving humans, as well as clinical trials of both statins and nonstatin lipid-modifying agents. In a meta-analysis that included more than 90,000 participants in 14 randomized trials of statins, the Cholesterol Treatment Trialists’ (CTT) collaborators found that, on average, a reduction of 1 mmol per liter (38.7 mg per deciliter) in LDL cholesterol levels yields a consistent 23% reduction in the risk of major coronary events over 5 years.
