Herein we present the case of a 27-year-old male patient who was recently diagnosed with Systemic Lupus Erythematosus (SLE) associated with nephritis with atypical findings on kidney biopsy and premature cardiovascular disease despite scarce traditional risk factors and negative laboratory findings for antiphospholipid syndrome. A literature review on the epidemiology and pathogenesis of coronary disease in SLE was conducted. The patient was admitted for pulse therapy after refractory disease on outpatient care but evolved with ventricular fibrillation secondary to acute thrombosis in the proximal segment of the anterior left descending artery, with no evidence of atherosclerotic disease. Laboratory findings were also negative for antiphospholipid syndrome both upon diagnosis and after the coronary event.  He underwent manual thrombus aspiration and angioplasty with a drug-eluting stent, successfully weaning off mechanical ventilation and vasopressors at the intensive care unit and showing no neurological deficits or left ventricular function impairment. Kidney biopsy later resulted positive for immunoglobulin A nephropathy. The patient was discharged asymptomatic on guideline-directed therapy for coronary disease, warfarin associated with clopidogrel, anti-hypertensive drugs and a combination of immunosuppressants, remaining well on three-month follow-up. SLE is a chronic inflammatory disease that has increasingly been recognized as a major cardiovascular risk factor due to a variety of mechanisms involving accelerated atherosclerosis and thrombosis. As patients survive the first years of disease onset from infection and disease-specific complications, cardiovascular outcomes become a great concern. However, early events such as in this case are possible, especially in the context of flaring disease. We emphasize the importance of an interdisciplinary approach to such patients for better outcomes.
