%X We enrolled 29 SSc patients (28 female, 65¡À4 years) and 30 controls (23 female, 64¡À2 years). Echocardiographic study with tissue Doppler imaging (TDI) and 2D strain analysis was performed; moreover, patients were submitted to a two-year follow-up for the occurrence of cardiovascular events.Standard echocardiographic parameters and TDI velocities were comparable between groups. LV longitudinal (LS) and circumferential (CS) strains were lower in patients than in controls (£¿13.1¡À4.8 vs £¿22.6¡À4.1, p < 0.001; -15.3¡À6.2 vs £¿20.4¡À5.6, p = 0.001), whereas radial strain (RS) was comparable between groups; moreover, a significant correlation of LS and CS with serum levels of Scl-70 antibodies was found (r = 0.74, p = 0.001; r = 0.53, p = 0.025). In addition, patients with cardiovascular events during follow-up showed a greater impairment of LS and CS (£¿10.3¡À2.5 vs £¿14.4¡À4.1, p = 0.015; -14.2¡À3.1 vs £¿20.1¡À1.6, p = 0.048) and higher values of Scl-70 antibodies serum levels (p = 0.047).The impairment of LV function, often subclinical, worsens prognosis of SSc patients, leading to increased risk of cardiovascular complications. 2D strain, allowing the early detection of LV abnormalities and the identification of patients at greater cardiovascular risk, may be a useful tool in order to provide a more accurate management of SSc patients.Systemic sclerosis (SSc) is an autoimmune disease characterized by inflammation, widespread vascular lesions and fibrosis involving various tissues and organs such as skin, lungs, gastrointestinal tract, kidneys, heart and blood vessels [1-3]. Multiple cardiac abnormalities, including ventricular arrhythmias, conduction disturbances, pericardial effusion, myocardial fibrosis and ischaemia, have been, frequently, reported in SSc and associated to a worse clinical course of the disease [4]. In particular, right ventricular (RV) dysfunction, commonly associated with pulmonary hypertension, has been, traditionally, considered as the hallmark of cardiac
