HIV-related dilated cardiomyopathy, atrial fibrillation, elevated circulating immune complexes, protein C deficiency, protein S deficiency, disseminated intravascular coagulation, D-dimer ≥500 ug/L, elevated highly sensitive C-reactive protein, insulin resistance, elevated level of antibodies against oxidized LDL-cholesterol, and antiphospholipid syndrome were similarly (P > .05) frequent in the group with ischemic stroke (n = 17) and the group without stroke (n = 99). The gene discussed is CRP; the disease is dilated cardiomyopathy.
