Clinical manifestations of patients with systemic lupus erythematosus and coronary artery disease / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical characteristics of patients with systemic lupus erythematosus (SLE) and coronary artery disease (CAD).</p><p><b>METHODS</b>Clinical data of 3911 SLE patients were retrospectively analyzed and CAD was diagnosed by coronary angiography in 26 (0.7%) SLE patients (10 stable angina pectoris, 5 unstable angina pectoris, 8 STEMI and 3 non-STEMI). The tradition risk factors, first onset of cardiac events, blood biochemistry index, treatment and activity of SLE, coronary angiographic features were compared with 552 CAD patients without SLE.</p><p><b>RESULTS</b>Compared with CAD patients without SLE, CAD patients with SLE were younger [(50.4 ± 15.2) years vs. (60.6 ± 11.6) years, P < 0.01], the mean number per patient of Framingham tradition risk factors was less (1.11 ± 1.18 vs. 2.50 ± 1.28, P < 0.05). CAD patients with SLE were prone to premature coronary artery disease [76.9% (20/26)], and ACS was the most common manifestation in SLE patients with premature coronary artery disease [65.0% (13/20)], the duration of steroid use was significantly longer [24.00 (3.75, 57.00) months vs. 1.00 (0.00, 2.00) months, P < 0.05] and 24 hours total urine protein [(1.93 ± 1.97) g vs. (0.76 ± 0.75) g, P < 0.05] was significantly higher in the ACS patients with SLE than non-ACS patients with SLE. Coronary stenosis was evidenced in most of the SLE patients with CAD [76.9% (20/26)] and incidence of coronary thrombotic occlusion was significantly higher in SLE patients with CAD than CAD patients without SLE [30.8% (8/26) vs. 11.8% (65/552), P < 0.05].</p><p><b>CONCLUSION</b>The incidence of CAD in SLE patients is low and the major form of CAD in SLE patients is premature coronary artery disease and mostly induced by coronary thrombotic occlusion.</p>
