Declaring war on undertreatment: rationale for an aggressive approach to lowering cholesterol.

Few things are better understood within the medical community than the relationship between elevated total and low-density lipoprotein cholesterol (LDL-C) levels, cardiovascular disease and death. There is consensus in the treatment guidelines of numerous national and international bodies that cholesterol levels in at-risk patients should be reduced to target levels that have been shown in population studies to be associated with low rates of coronary heart disease (CHD). However, dyslipidaemia continues to be underdiagnosed and undertreated. The 'landmark' statin trials have demonstrated unequivocally that effective lipid-lowering therapy significantly decreases CHD morbidity and mortality. Furthermore, these benefits of lipid-lowering therapy are not limited to middle-aged men, but extend across a broad range of patient populations. Recent trial data suggest that lowering LDL-C to target levels is possible in a substantial proportion of patients when statins are administered aggressively and results in a greater reduction in the risk of major coronary events. This reduction in events is seen in patients with stable coronary disease as well as those treated immediately after an acute coronary syndrome. Although strong clinical and angiographic evidence shows that intensive treatment prevents morbidity and saves lives, indications are that clinicians are still waiting too long to treat dyslipidaemia and when treatment is initiated it is often at inadequate dosages. Undertreatment of dyslipidaemia is an issue that the healthcare community can no longer ignore.
