A young woman was diagnosed with systemic lupus erythematosus at the age of 7 years and incurred an acute myocardial infarction at the age of 17 years. Her risk factors for coronary artery disease include hypertension, hypercholesterolemia, a relatively long disease duration, a fairly active disease as evidenced by the history of nephrotic syndrome and other organ system involvement, and a long history of prednisone use. It is difficult to determine the etiology of this patient's acute myocardial infarction without coronary artery histopathology, but aspects of her presentation (a history of virulent systemic lupus erythematosus, and the angiographic findings of ectasia and aneurysm) suggest that coronary arteritis was the etiology of her accelerated coronary artery disease and subsequent myocardial infarction. Acute myocardial infarction is an uncommon occurrence in premenopausal women less than 30 years old.35 These patients are typically found to have an associated systemic disease such as diabetes mellitus or familial hypercholesterolemia. Systemic lupus erythematosus is a less common systemic disease associated with premature coronary artery disease. Mechanisms of acute coronary syndromes in these patients include accelerated atherosclerosis, active coronary vasculitis, and/or vasospasm with superimposed thrombosis.

Acute myocardial infarction is an important and sometimes fatal complication of systemic lupus erythematosus (SLE). We describe a case of acute myocardial infarction in a 23-year-old woman with SLE. Angiography revealed coronary ectasia in the left main and proximal circumflex coronary arteries, as well as a stenotic lesion in the left anterior descending artery. The possible pathophysiology is discussed.

Anticardiolipin antibodies (ACAs) of IgA, IgG, and IgM isotypes were measured using an enzyme-linked immunosorbent assay (ELISA) in patients with SLE, and in other groups of subjects with a higher or lower risk of developing thrombosis. IgA ACAs were present in high titers in all groups and had little discriminant value in predicting thrombotic risk. In patients without the lupus anticoagulant (LAC) with conditions in which a thrombotic tendency was a feature (primigravidae with preeclampsia or intrauterine growth retardation, patients with angina or acute myocardial infarction, those on anticoagulant therapy for apparently spontaneous thrombosis, and patients with Behcet's syndrome in whom there was a history of thrombosis) ACAs of all isotypes were present in 44/191 (23%). In patients in whom a thrombotic tendency was not a feature (normal controls, primigravidae with normal deliveries, patients with rheumatoid arthritis, and with Behcet's syndrome in whom there was no thrombotic history) 22/241 (9%) had ACAs. Although ACAs were more likely to be present in a subset of patients without systemic lupus erythematosus (SLE) and/or the LAC, their presence was a poor discriminator of increased risk of thrombosis.

We report a 22-year-old man who successfully underwent coronary stent implantation after an acute myocardial infarction. Lupus anticoagulant and antibodies against cardiolipin and prothrombin were detected despite the absence of any underlying disease. Therefore, long-term oral anticoagulation was instituted and appeared to be effective. To our knowledge this is the first report on coronary stenting in primary antiphospholipid syndrome.

The authors present the cases of two young patients, a man and a woman, who presented with myocardial infarction, in the absence of ischemic heart disease or stenosis of the coronary arteries. The woman was known to have systemic lupus erythematosus (SLE) for the past 3 years (the immunoglobulin M [IgM] anticardiolipins antibodies were positive), without a history of coronary risk factors. Suddenly she presented with acute chest pain on rest that lasted 4 hours and culminated in anterior wall myocardial infarction. She was admitted to the coronary care unit, where no thrombolysis was given. She did not have echocardiographic evidence of Libman-Sacks endocarditis, but myocardial infarction was evident at the electrocardiogram (ECG). The young man had SLE (the IgM anticardiolipins were absent, but he was positive for lupus anticoagulant antibodies), he was hyperlipidemic, was a moderate smoker and moderately obese, and had no history of ischemic heart disease. He suddenly presented with an acute myocardial infarction documented by ECG, enzymes, and gammagraphy. In both patients, coronary angiography findings were normal and myocardial biopsy did not show evidence of arteritis. The relevance of these cases is the rare association of ischemic heart disease in SLE, with normal coronary arteries and without evidence of arteritis or verrucous endocarditis.

We report two cases of coronary artery bypass grafting (CABG) associated with antiphospholipid syndrome (APS) in systemic lupus erythematosus (SLE). Patient 1, 65-year-old female, who had been treated for SLE with prednisolone for 11 years was transferred to our hospital due to unstable angina caused by stenosis of the left main trunk (LMT) and the left anterior descending artery (LAD). She underwent emergency CABG of the LAD using left internal thoracic artery (LITA). Post operative doppler study demonstrated patent LITA to the LAD. Patient 2, 67-year-old female who had been treated for SLE with prednisolone for 8 years was transferred to our hospital due to acute myocardial infarction caused by stenosis of the LMT and the left circumflex artery (LCX). She underwent emergency CABG of the LAD and the LCX using saphenous vein grafts (SVGs). Post operative angiography confirmed a patent SVG to the LAD and an occuluded SVG to the LCX. In cases of SLE, the frequency of occurrences of ischemic heart diseases is high. Until now, however, there are few instances reported on performing CABG for patients with SLE. We are reporting here our particular cases of APS with SLE, discussing the involvement of APS as causative factor of ischemic heart diseases and related issue of surgical and post surgical antithrombotic treatments.

1. Macro- and microvascular diseases are the main chronic complications of diabetes mellitus (DM). 2. It has been shown that DM patients have more severe nailfold microcirculatory disturbances than patients with liver cirrhosis or systemic lupus erythematosus (SLE). 3. It has been shown that the glomerular basement membrane of diabetic rats is significantly thickened compared with that of normal rats (295.5 +/- 45.1 vs 184.8 +/- 33.2 nm). 4. Gastric mucosal blood flow (GMBF) in 41 patients with non-insulin-dependent diabetes mellitus (NIDDM) was determined with a laser Doppler flowmeter. The results showed that average GMBF values at 14 sites in the gastric mucosa were significantly lower in NIDDM patients than in control subjects. 5. The percentage of painless acute myocardial infarction (AMI) among 50 patients with DM was 22.0% and the mortality of AMI was 22.0% (11 cases). Both these values were higher than the corresponding values in patients without DM (9.9 and 11.4%, respectively; P < 0.05). 6. Cerebrovascular disease is more prevalent in diabetic patients than in non-diabetics and the mortality of stroke in DM patients is two-fold higher than that of non-diabetic patients. 7. Diabetes can result in widespread macrovascular atherosclerosis and microcirculatory disorders of multiple organs.

Cardiovascular and cerebrovascular diseases are common causes of morbidity and mortality in women with systemic lupus erythematosus (SLE) and are also common in patients with end-stage renal disease (ESRD). To determine whether women with ESRD caused by lupus nephritis are at greater risk for morbidity from these conditions than women with other causes of ESRD, data from the US Renal Data System were used to compare incidence rates of hospitalizations for acute myocardial infarction and cerebrovascular accident between women with ESRD caused by lupus nephritis and women with ESRD from other causes. The age- and race-adjusted incidences of hospitalizations for acute myocardial infarction during dialysis were 16.4 hospitalizations/1,000 patient-years among women with ESRD caused by lupus nephritis and 17.3 hospitalizations/1,000 patient-years among women in the comparison group (adjusted hazard ratio, 0.80; 95% confidence interval [CI], 0.58 to 1.08; P = 0.14). Adjusted incidence rates for acute myocardial infarction after renal transplantation also did not differ between these groups. Adjusted incidence rates for hospitalizations for cerebrovascular accident during dialysis were 18.5 hospitalizations/1,000 patient-years among women with ESRD caused by lupus nephritis and 19.2 hospitalizations/1,000 patient-years among women in the comparison group (adjusted hazard ratio, 0.87; 95% CI, 0.66 to 1.14; P = 0.30); incidence rates after transplantation also did not differ between groups. Risks for death from cardiovascular or cerebrovascular diseases also were not increased among women with ESRD caused by lupus nephritis. Sepsis was the most common cause of death in this group. Morbidity and mortality from acute myocardial infarction and cerebrovascular accident were substantially greater among women with ESRD caused by diabetes mellitus. Although morbidity and mortality from cardiovascular and cerebrovascular diseases are common among women with SLE, risks for these outcomes are not greater among women with ESRD caused by lupus nephritis than among other women without diabetes with ESRD.

Diabetic ketoacidosis and moderate degree of hyperglycemia can be managed by glucose-insulin-potassium (GIK) regimen. The GIK regimen is also useful in the treatment of acute myocardial infarction (AMI). But, the exact mechanism(s) of the beneficial action of GIK regimen is not known. I suggest that glucose-insulin can suppress the secretion and antagonize the harmful effects of tumor necrosis factor alpha (TNF alpha) and macrophage migration inhibitory factor (MIF). If this is true, it suggests that GIK regimen may be useful in septicemia and septic shock, and other inflammatory conditions such as ulcerative colitis, Crohn's disease, rheumatoid arthritis, systemic lupus erythematosus and cancer, conditions in which TNF alpha and MIF appear to play a major role.

A 55-year-old man developed acute myocardial infarction (AMI) related to a large coronary artery aneurysm and a distal coronary stenotic lesion after steroid therapy for systemic lupus erythematosus (SLE). Only 13 SLE patients with AMI caused by coronary artery aneurysms have been reported, 11 of whom were young or middle-aged women and the 2 remaining were young men. This is the first report of a middle-aged man with multiple coronary lesions.
