ABSTRACT
BACKGROUND:
Psoriasis has been shown to increase cardiovascular risk, and a contributor to this might be enhanced myocardial fibrosis promoted by the disease-associated pro-inflammatory milieu.OBJECTIVE:
We sought to investigate the relationship of galectin-3 (Gal-3) - a recognized mediator of fibrosis with inflammatory activation and left ventricular (LV) systolic and diastolic function in patients with psoriasis.METHODS:
We enrolled 102 psoriatic patients (mean age 52.5 ± 12.6 years). Sixty-five age- and sex-matched healthy subjects served as controls. Echocardiographic assessment of myocardial function included estimation of LV longitudinal systolic deformation (GLS) and diastolic indices tissue e' velocity and E/e' ratio. Laboratory measurements encompassed blood Gal-3, creatinine, glucose, insulin, CRP and erythrocyte sedimentation rate (ESR).RESULTS:
Patients with psoriasis were characterized by elevated Gal-3 (12.3 [9.3-13.4] vs. 6.3 [5.5-9.4] ng/mL in healthy controls, P < 0.001), ESR (17.0 [11.0-29.0] vs. 8.5 [6.0-13.0] mm, respectively, P < 0.001) and CRP (3.1 [1.7-10.6] vs. 1.9 [1.5-4.0] mg/L, respectively, P < 0.001), and reduced GLS (19.9 ± 3.7 vs. 22.0 ± 3.0%, respectively, P < 0.001). Progressive deterioration of GLS was demonstrated across Gal-3 tertiles. Significant associations between GLS and age (beta = -0.21, P < 0.04), Gal-3 (beta = -0.27, P < 0.01), CRP (beta = -0.22, P < 0.03), ESR (beta = -0.25, P < 0.01), waist circumference (beta = -0.22, P < 0.03) and waist-to-hip ratio (beta = -0.20, P < 0.05) were found. Stepwise multiple regression analysis revealed that the independent determinants of GLS in psoriatic patients were Gal-3 (beta = -0.24, P < 0.01) and ESR (beta = -0.21, P < 0.03). Regression-based mediation analysis demonstrated that the relationship between ESR and GLS was partially mediated by Gal-3.CONCLUSIONS:
Subclinical left ventricular systolic dysfunction in psoriasis, as evidenced by reduced GLS, is linked with the inflammatory upregulation, and enhanced profibrotic activity (as reflected by elevated serum Gal-3) may be involved in this process. These putative mechanisms may be responsible for the observed higher incidence of heart failure in this disease condition and should be considered as a potential target for preventive and therapeutic measures.
