Risk factors of cardiovascular involvement in patients with Behcet?s disease

Objectives: Behcet's disease (BD) is a multi-systemic inflammatory vasculitis which may be life-threatening if combined with cardiovascular problems. The aim of the study was to identify potential risk factors associated with cardiovascular involvement in BD.Methods: We reviewed the medical databases of a single center. All BD patients identified as fulfilling the 1990 International Study Group criteria or the International Criteria for Behcet's Disease criteria. Cardiovascular involvement, clinical manifestations, laboratory features, and treatments were recorded. The relationship be-tween parameters and cardiovascular involvement was analyzed.Results: 111 BD patients were included: 21 (18.9%) had documented cardiovascular involvement (CV BD group) and 99 (81.1%) had no cardiovascular involvement (non-CV BD group). Compared with non-CV BD, the pro-portion of males and smokers were significantly increased in CV BD (p = 0.024 and p < 0.001, respectively). Levels of activated partial thromboplastin time (APTT), cardiac troponin I and C-reactive protein were signifi-cantly higher (p = 0.001, p = 0.031, and p = 0.034, respectively) in the CV BD group. Cardiovascular involvement was associated with smoking state, the presence of papulopustular lesions, and higher APTT in multivariate analyzed (p = 0.029, p = 0.021, and p = 0.006, respectively). The ROC curve showed that APTT predicts the risk of cardiovascular involvement (p < 0.01) at a cut-off value of 33.15 s with a sensitivity of 57.1% and specificity of 82.2%.Conclusion: Cardiovascular involvement in BD patients was associated with gender, smoking state, the presence of papulopustular lesions, and higher APTT. All patients newly diagnosed with BD should be systematically screened for cardiovascular involvement.
