Prevention of cardiovascular events in elderly hypercholesterolemic patients.
The management of hyperlipidemia in the elderly patient is a major problem, given the frequency of dyslipidemias and cardiovascular disorders in this age group. Therapy must take current uncertainties into account and, in the absence of therapeutic studies carried out in the elderly, is typically based upon a case-by-case approach. Raised cholesterol levels remain a significant risk factor for coronary heart disease (CHD) in the elderly. Although the relative risk of CHD tends to diminish with increasing age, this reduction is accompanied by an increase in absolute risk (ie, the number of events) as the frequency of the illness increases markedly with age. The results of major outcome studies with 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins), when analyzed according to patient age, indicate that the benefits of these agents are not merely confined to younger individuals. However, the elderly form a unique patient population--the proportion of women is greater and the profile of cardiovascular illnesses is characterized, among others, by a greater incidence of cerebrovascular accidents. Problems relating to poor tolerability and comorbidity (which may give rise to drug-drug interactions) also occur more frequently in this age group. Moreover, the potential widespread treatment of hyperlipidemia in the elderly has profound economic implications. Under these circumstances, the clinical practice recommendations depend upon a reasonable extrapolation of epidemiologic and therapeutic data obtained from middle-aged men. At present, treatment is therefore aimed at patients with the most severe forms of hyperlipidemia, generally in the secondary prevention setting, taking into account the patient's life expectancy. The results of ongoing studies will determine the benefits of lipid-lowering therapy for primary prevention of CHD in the elderly.
