AIM: Visfatin may play a part in reverse left ventricular remodelling. Using a mouse model of reversible left ventricle pressure overload, we examined if visfatin was altered in the myocardium. Furthermore, we addressed this issue in patients with aortic stenosis (AS) and examined whether visfatin levels are related to reverse remodelling following aortic valve replacement (AVR). METHODS: Myocardial visfatin was analysed after aortic banding (AB) and debanding (DB) in mice and compared to sham operated animals. Myocardial visfatin was measured in biopsies from patients undergoing AVR and compared to controls. Serum visfatin was measured before and after AVR in patients with AS and correlated with echocardiographic measurments of cardiac morphology and function. RESULTS: Four weeks after AB, myocardial visfatin protein was reduced by 50% compared to sham. Three days after DB, myocardial protein levels increased significantly. Myocardial visfatin and serum visfatin levels were reduced by 23% and 64%, respectively, in patients with AS compared to controls. Twelve months after AVR, serum visfatin levels increased compared to preoperative values and correlated negatively with degree of left ventricular hypertrophy. CONCLUSION: Myocardial visfatin and serum visfatin levels are reduced by cardiac pressure overload. Visfatin levels increase after correction of pressure overload and may play a part in postoperative reverse remodelling.
