Cardiovascular disease (CVD) is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Patients with SLE have an excess risk compared with the general population; this is particularly pronounced in younger women with SLE who have an excess risk of over 50-fold compared with population controls. There is a higher prevalence of subclinical atherosclerosis in patients with SLE compared with controls, as demonstrated by a variety of imaging modalities discussed in this review. The causality of the excess risk of CVD and subclinical atherosclerosis is multifactorial in patients with SLE. While traditional risk factors play a role, after controlling for the traditional Framingham risk factors, the excess risk is still 7.5-fold greater than the general population. This review will also cover novel cardiovascular risk factors and some SLEspecific variables that contribute to CVD risk. This review discusses the risk factor modification and the evidence available for treatment of these risk factors in SLE. There have not yet been any published randomized, controlled trials in patients with SLE with respect to CVD risk factor modifications. Thus, the treatment and management recommendations are based largely on published guidelines for other populations at high risk for CVD.
Keywordscardiac imaging; cardiovascular disease; cardiovascular risk factors; subclinical atherosclerosis; systemic lupus erythematosusIn the last few decades, the prognosis of patients with systemic lupus erythematosus (SLE) has improved immensely. In the 1950s, the 5-year survival rate for SLE was approximately 50% according to a study performed in Toronto, Canada. Subsequent studies have found 5-year survival rates of 90% in patients with SLE [1]. A bimodal mortality pattern was first described in 1976 by Urowitz et al. in the Toronto Lupus cohort. Septicemia in the setting of high-dose prednisone was identified as an early cause of death in patients with more active SLE. Later in the disease course, death was associated with inactive SLE, long duration of prednisone therapy and myocardial infarction (MI) due to atherosclerotic heart disease [2]. More recent data from a large international cohort revealed a 60% decrease in the standardized all-cause mortality rates (SMR) from 1970-1979 (SMR: 4.9) to 1990. However, the SMR trend for cardiovascular disease (including heart disease, arterial disease and stroke) did not decline from 1970 to 2001 [3]. A Swedish cohort followed from 1964 to 1994 demonstrated similar findings of improved overall survival for patients with SLE over the last two decades, but the risk of cardiovascular death remained (by 1985-1994
