BackgroundInflammatory markers such as serum C-reactive protein (CRP), serum amyloid A (SAA), and plasma pentraxin 3 (PTX3), which belong to the pentraxin superfamily, increase due to various inflammatory diseases. Some studies demonstrated that serum CRP and SAA are predictors of cardiovascular diseases, and cardiac rehabilitation (CR) induces anti-inflammatory effects. In the present study, we investigated the effects of CR on pentraxins (serum CRP, SAA, and plasma PTX3) in patients with cardiovascular diseases.MethodsFifty patients with cardiovascular diseases [61 ± 13 (mean ± SD) years old, male/female 44/6] participated. Each subject performed CR using aerobic bicycle exercise two or three times per week for 3-6 months. We measured resting serum high-sensitivity CRP (hsCRP), SAA, and plasma PTX3 before and 3 and 6 months after CR, and compared them with VO(2peak) determined using a standard increment cycle ergometer protocol, B-type natriuretic peptide (BNP), and other biochemical data such as HbA1c.ResultsThere was a significant positive correlation between hsCRP and SAA (r = 0.92, p < 0.001), but no relations between these parameters and PTX3. Plasma PTX3 significantly decreased time dependently during CR (at baseline 3.2 ± 2.0 ng/ml, at 3 months 2.3 ± 0.8 ng/ml, at 6 months 2.1 ± 0.7 ng/ml; all p < 0.05). Serum hsCRP tended to decrease, but not statistically significantly. At baseline, plasma PTX3 was negatively correlated with the percentage of the predicted values of VO(2peak) and positively correlated with BNP. CR significantly increased the percentage of the predicted values of VO(2peak) and decreased BNP.ConclusionsPlasma PTX3, an inflammatory marker, which was quite different from CRP and SAA, decreased during cardiac rehabilitation with an improvement of exercise capacity in patients with cardiovascular diseases.
