Known risk factors for coronary artery disease are very common in the Hopkins
Lupus
Cohort, in spite of the fact that the average patients age is only 38.3 years. Three or more known risk factors were found in 53% of patients. Risk factors for
CAD
were common even in patients not on a regimen of prednisone therapy during their cohort follow-up. Hypercholesterolemia increased significantly with greater average prednisone dose. Despite the frequency of risk factors, patients' awareness of the risk of
CAD
was low, with only 16.9% of patients believing they were at high risk for developing
CAD
within 5 years. In general, awareness of individual risk factors was lower in black than in white patients with SLE. Preventive practices were most commonly addressed towards hypertension. Preventive practices directed against obesity, hypercholesterolemia, and smoking were underutilized. Whether these known risk factors are sufficient in and of themselves to explain the high frequency of
CAD
in the cohort (8%) or whether they are "enabling" factors acting upon endothelium damaged by immune-complex disease cannot be addressed by this study. However, both further investigation of these risk factors and attention to lifestyle and pharmacologic approaches to risk factor reduction are indicated by this study.

Our purpose was to examine prospectively the relationship between systemic hypertension and vascular events in patients with SLE. SLE patients followed in the University of Toronto
Lupus
Clinic presenting between 1980 and 1988 and within one year of their diagnosis of SLE were identified. Standard definitions were used for hypertension and for all vascular events (MI, angina, CVA, PVD). The presence of traditional
CAD
risk factors, along with disease- and therapy-related risk factors for the development of vascular disease, were compared in the hypertensive and normotensive group. A multivariate logistic regression was performed to determine the best predictor of a vascular event. One hundred and fifty patients were identified in our inception cohort [75 hypertensive (50%) and 75 (50%) normotensive]. Seventeen hypertensive patients (22.7%) had at least one vascular event as compared to six (8.0%) normotensive patients (p = 0.022). The vascular events included 7 with
CAD
, 5 with CVA, and 5 with PVD in the hypertensive group while in the normotensive group 3 patients developed
CAD
, 2 CVA and 1 PVD. Fifteen deaths were recorded in the hypertensive group as compared to eight deaths in the non-hypertensive groups (P = 0.09). The groups were comparable with respect to associated risk factors, except for higher frequency of hypercholesterolemia (P = 0.003), azotemia (P = 0.001) and corticosteroid use (P = 0.038) in the hypertension group. In a multivariate analysis the best predictor of a vascular event was hypercholesterolemia (OR 6.9, 95% CI 2.4-24.8, P < 0.001). We conclude that systemic hypertension is associated with an increased frequency of vascular events in SLE. This is best explained by its association with hypercholesterolemia.

To determine the prevalence of dyslipoproteinemia on a large juvenile systemic lupus erythematosus (jSLE) cohort, we selected 40 patients after rigorous exclusion criteria. Lipoprotein levels were determinated after 12 hours fast and risk levels for
CAD
were defined by standards of the Brazilian Guidelines for dyslipoproteinemia according to US-NCEP. All individuals were under steroid therapy and chloroquine and 43% had active disease. Thirty patients (75%) had high-risk levels for
CAD
(23 isolated low HDL, while in seven subjects low HDL was associated to high TG in four, high LDL in one, high TG/LDL in one and high TC/LDL in one). Remarkably, overall analysis revealed that 85% patients were included in high/medium risk levels group (29% for TC, 29% for LDL, 88% for HDL, and 18% for TG) and these disturbances occured mainly in the first four years of disease. Unexpectedly, one-third of the patients presented two or more high/medium lipoprotein risk factors. Independently, active jSLE was associated to TG (OR = 3.2; P < 0.001) and had a tendency towards reduction on HDL (OR = 8.5; P = 0.056). Considering improvements on jSLE outcome, the increased frequency of high/medium lipoprotein risk levels for
CAD
reinforces the need of prevention measures in order to minimize deleterious effects of this disturbance.

Antiphospholipid syndrome (APS) is a systemic autoimmune disease associated with arterial and venous thrombotic events and recurrent fetal loss. Cardiac manifestations in APS primarily include accelerated atherosclerosis leading to cardiovascular disease. There is increased cardiovascular mortality in APS. Cardiovascular risk is even higher in secondary APS in
lupus
patients. Several traditional and disease-related, autoimmune-inflammatory risk factors are involved in APS-associated atherosclerosis and its clinical manifestations. Antiphospholipid antibodies (APA),
lupus
anticoagulant, anti-oxLDL and other antibodies have been implicated in vascular events underlying APS. The primary and secondary prevention of atherosclerosis and
CAD
in these diseases includes drug treatment, such as the use of statins and aspirin, as well as lifestyle modifications. Apart from atherosclerosis and CVD, other cardiac manifestations may also be present in these patients. Among these conditions, valvular disease including thickening and vegetations is the most common. APA are involved in the pathogenesis of Libman-Sacks endocarditis usually associated with SLE. In addition, ventricular dysfunction, intracardiac thrombi and myxomas, pulmonary hypertension may also exist in APS patients. Early diagnosis of APS, thorough examination of the heart, control of traditional risk factors by lifestyle modifications and pharmacotherapy, probably anti-inflammatory treatment, and close follow-up of APS patients may help to minimize cardiovascular risk in these individuals.

In 35 patients with 116 severe premature cardiovascular disease (CVD) events (median age: 48 years), 14 having worsening CVD despite maximal intervention, we evaluated thrombophilia and speculated that anticoagulation might arrest-reverse progressive thrombophilic-atherothrombotic CVD. Thrombophilia-hypofibrinolysis in the 35 patients was compared to 110 patients with venous thromboembolism (VTE) without CVD and to 110 healthy normal controls. Efficacy-safety of anticoagulation was prospectively assessed in 14 of the 35 patients whose CVD worsened over 2 years despite maximal medical-surgical intervention. At entry on maximally tolerated lipid-lowering therapy, median low-density lipoprotein was 88 mg/dL. Measures of thrombophilia-hypofibrinolysis in the 35 cases differed from 110 VTE controls only for the
lupus
anticoagulant, present in 6 (21%) of 28 cases versus 4 (4%) of 91 VTE controls ( P = .01), and for high anticardiolipin antibodies (ACLAs) immunoglobulin G, 5 (14%) of 35 cases versus 4 of 108 VTE controls (4%), P = .04. The 14 patients who were anticoagulated differed from 110 VTE controls only for the
lupus
anticoagulant, 38% versus 4%, P = .001, and for high lipoprotein (a), 46% versus 17%, P = .028, respectively. The 14 patients with atherothrombosis having inexorably worsening
CAD
despite maximal medical-surgical therapy were anticoagulated for 6.5 years (median), with clinical CVD progression arrested in 12 (86%), and all 12 became asymptomatic. In the 35 patients with premature CVD, thrombophilia was pervasive, comparable to or more severe than in VTE controls without CVD. When CVD progressively worsens despite maximal intervention, thrombophilia and atherosclerosis (atherothrombosis) are commonly concurrent, and the downhill course of CVD may be arrested-stabilized by anticoagulation.
