Abstract

OBJECTIVES: Macrovascular involvement and cardiovascular (CV) risk has not been sufficiently studied in mixed connective tissue disease (MCTD). In particular, the gold standard assessment method of aortic stiffness carotid-femoral pulse wave velocity (cfPWV) has never been evaluated in patients with this disease. The aims of the present study were therefore to examine cfPWV in MCTD and to evaluate its associations with MCTD-associated markers and traditional CV risk factors. METHODS: Measurements of cfPWV were performed in 43 MCTD patients and 107 healthy controls. The difference between cfPWV in the two groups was statistically examined and subsequently controlled for the effect of possible confounding factors. The association of cfPWV with MCTD-associated organ involvement, routine laboratory parameters and immunoserological markers was also evaluated. Finally, the relationship of cfPWV with medications and traditional CV risk factors was examined. RESULTS: Adjusted statistical analyses for confounding factors showed significantly higher cfPWV values in MCTD patients in comparison to controls (padj<0.001). cfPWV correlated in both the patients and the control group significantly with age (rho=0.69, p<0.001 and rho=0.67, p<0.001 respectively) and diastolic arterial pressure (padj=0.024 and padj=0.032 respectively). Moreover, cfPWV correlated in the control group with systolic and mean arterial pressure (padj<0.001 and p=0.002 respectively). Finally, higher cfPWV values could be documented in the subset of MCTD patients without lung involvement (padj=0.007). CONCLUSIONS: Patients with MCTD have significantly higher aortic stiffness and thus CV risk in comparison to controls. Except for the disease itself, age and blood pressure were the main predictors of cfPWV.
