Cardiovascular disease is not the result of a single disease but is th
e sum of multiple comorbid conditions that act independently and in ta
ndem to create an increased probability for heart disease and stroke.
More than 200 risk factors and/or comorbid diseases for cardiovascular
disease have been identified. The correct diagnosis of comorbid disea
ses is integral to being able to accurately interpret individual risk
profiles and to construct a rational treatment paradigm that allows mu
ltiple modalities of care. In a time when optimal delivery of healthca
re is linked to the most cost-effective allocation of limited resource
s, determining overall risk and defining the most effective interventi
on strategies is not an idle intellectual exercise but a matter of vit
al necessity. Identifying common comorbid diseases that can exist with
hyperlipidemia is essential for appropriate treatment and risk reduct
ion. In addition to being able to identify comorbid diseases, clinicia
ns must have an understanding of how these comorbid conditions interre
late and affect overall cardiovascular health. The primary objective o
f treating hypercholesterolemia is to reduce the patient's risk of dev
eloping cardiovascular disease. Modifying the additional risks that ar
e introduced by comorbid diseases is appropriate and necessary. Therap
y for comorbid conditions will add to the benefit obtained from, but c
an never be substituted for, the primary goal-reduction of low-density
lipoprotein cholesterol.
