Background Systemic sclerosis is characterised by progressive cutaneous and organ fibrosis. Among all organs, a subclinical heart involvement is difficult to detect through conventional imaging. Design We evaluated whether speckle tracking-derived global longitudinal strain could help detect early subclinical systolic dysfunction in systemic sclerosis patients without overt clinical involvement. Methods A case–control, single-centre study on 52 systemic sclerosis patients and 52 age and gender-matched controls. Patients with structural heart disease, heart failure, atrial fibrillation and pulmonary hypertension were excluded. For every patient, standard echocardiographic and speckle tracking-derived variables for the systolic and diastolic function of the left ventricle and right ventricle were acquired. Results Traditional parameters of left and right systolic function did not differ between systemic sclerosis patients and controls (all P = ns). Left and right ventricular global longitudinal strain was significantly impaired in patients with systemic sclerosis when compared to controls (–19.2% vs. –21.1%; P = 0.009 and –18.2% vs. –22.3%; P = 0.012, respectively). Systemic sclerosis patients had a 2.5-fold increased risk of subclinical left ventricular systolic impairment (odds ratio 2.5, 95% confidence interval 1.1–5.5; P = 0.027) and a 3.3-fold increased risk of subclinical right ventricular systolic impairment when compared to controls (odds ratio 3.3, 95% confidence interval 1.4–7.7; P = 0.004). Alterations in the myocardial deformation pattern of systemic sclerosis patients were homogeneous in the right ventricle and eccentric in the left ventricle. Conclusions While traditional echocardiographic parameters are ineffective in detecting subclinical systolic impairment, reduced global longitudinal strain is common in patients with systemic sclerosis and significant for both ventricles. Global longitudinal strain could become a low-cost, non-invasive and reliable tool in order to detect early cardiac involvement in systemic sclerosis patients.

Abstract Funding Acknowledgements Type of funding sources: None. Background High-flow nasal cannulae oxygen therapy (HFNCOT) represents a better tolerated alternative to non-invasive pressure support ventilation (NIPSV) for acute cardiogenic pulmonary edema (ACPE) treatment. However, there are still few data on the effect of HFNCOT on cardiac function and hemodynamic. Purpose To assess and compare the effects of NIPSV and HFNCOT in ACPE setting on right ventricular (RV) systolic function and on indices of cardiac filling and output, as measured by echocardiography.  Methods  This is a cross-over controlled study, enrolling 15 consecutive patients admitted to our Cardiovascular Intensive Care Unit for ACPE and hypoxaemic, normo/hypocapnic acute respiratory failure, with P/F ratio < 200. Each patient received NIPSV, followed by HFNCOT. Full echocardiographic assessment and blood gas analysis (BGA) were performed 40 minutes from onset of each ventilation modality, respectively before NIPSV to HFNCOT switch and before HFNCOT interruption. In particular, RV function parameters, together with RV and atrial strain, were prospectively collected. Results  In spite of not significant changes in BGA, RV function was significantly improved under HFNCOT, as compared to NIPSV, as assessed by the following parameters: tricuspid annular plane excursion (TAPSE) (P = 0.001), RV S’ wave (P = 0.007), RV fractional area change (RVFAC) (P = 0.006). Strain analysis confirmed the significant improvement in RV function, with free wall global longitudinal strain (GLS) and free wall and septum GLS significantly higher under HFNCOT, as compared to NIPSV (-21% vs -18% P < 0.001, and -15% vs -19% P = 0.008, respectively,), and a significant increase in right atrial positive longitudinal strain (P < 0.001).  Conclusions NIPSV significantly affect RV function making more complex the management of patients presenting with ACPE. In this setting, HFNCOT represents a valuable alternative, providing similar respiratory outcomes while preserving good right ventricle performance.
