Sažetak
Background Left ventricular diastolic dysfunction (LVDD) is the most common cardiac abnormality in systemic sclerosis (SSc). It is known that aging is a primary determinant of LVDD in SSc patients and many of the clinical factors associated with LVDD were no longer associated after simply adjusting for age. Objectives The aim of this study was to determine clinical and laboratory parameters of SSc patients with and without LVDD matched for age. Methods We studied 13 SSc patients with preserved left ventricular ejection fraction (LVEF) and LVDD, and 13 SSc patients without LVDD matched for age, sex, body mass index and smoking status. LVDD was defined and classified according to the American Society of Echocardiography recommendations. Serum IL-6 and NT-proBNP levels were measured and subjects were evaluated by conventional and pulsed-wave tissue Doppler echocardiography and by the six minute walk test (6MWT). Results There was no difference between SSc patients with and without LVDD according to heart rate, systolic and diastolic blood pressure, left ventricular mass index, prevalence of pulmonary artery hypertension, and antibody status. SSc patients with LVDD had longer duration of SSc than SSc patients without LVDD (16.0 vs 6.65 yrs ; P=0.004), and had higher EUSTAR score (5.77 vs 3.12 ; P=0.001). The serum level of IL-6 (6.39 vs 2.94 pg/ml ; P=0.021) and NT-proBNP (24.78 vs 10.12 pmol/L ; P=0.003) were significantly increased in SSc patients with LVDD. The 6MWT distance was shorter in SSc patients with LVDD as compared to those without LVDD (326.46 vs 398.69 m ; P=0.034). Also, desaturation during the 6MWT was more significant in SSc patients with LVDD (-3.38% vs -1.92% ; P=0.022). Conclusions SSc patients with LVDD had longer disease duration and higher disease activity (EUSTAR) scores. SSc patients with LVDD showed significantly increased serum IL-6 and NT-proBNP levels in comparison with those without LVDD. LVDD is associated with decreased exercise capacity in SSc patients.
