Background: Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder with potential cardiovascular involvement. The aim of this study was to assess left ventricular (LV) systolic function in a large cohort of patients with SLE using standard echocardiographic measurements and global longitudinal strain (GLS) by two-dimensional speckle-tracking analysis. Furthermore, the association between echocardiographic parameters and the occurrence of cardiovascular events was assessed. Methods: A total of 102 patients with SLE (88% women; mean age, 43 6 14 years) undergoing a dedicated multidisciplinary assessment were analyzed, including echocardiography, at the time of their first visit. A control group consisted of 50 age-and sex-matched healthy subjects. Results: Compared with control subjects, patients with SLE showed impaired LV systolic function on the basis of LV ejection fraction (51 6 6% vs 62 6 6%, P < .001) and by LV GLS (À15 6 3% vs À19 6 2%, P < .001). During a median follow-up period of 2 years (interquartile range, 1-6 years), 38 patients (37%) developed cardiovascular events. Kaplan-Meier survival curves showed that patients with SLE with more impaired LV GLS (on the basis of the median value of À15%) experienced higher cumulative rates of cardiovascular events compared with those with less impaired LV GLS (c 2 = 8.292, log-rank P = .004). On multivariate Cox regression analysis, LV GLS demonstrated an independent association with cardiovascular events (hazard ratio, 2.171; 95% CI, 1.015-4.642; P = .046), whereas LV ejection fraction was not significantly associated with the outcome. Conclusions: In patients with SLE, LV systolic function as measured by LV GLS is significantly impaired and associated with cardiovascular events, potentially representing a new tool to improve risk stratification in these patients.

In the majority of developing economies there has been limitation to rapid growth of technologyrich and expensive broadband telecommunication infrastructure (e.g. optical fiber networks), which is prerequisite of e-Health. However, along with the emergence of broadband mobile communication networks, mHealth seems advantageous and costefficient mode of e-Health in those countries, likewise Georgia. The first mHealth project in Georgia on m-Telemonitoring (MTM-1) of Cardiac arrhythmia -54 patients with main medical results, Quality of Service (QoS), Quality of Experience (QoE), cost-efficiency and remaining challenges -is presented, as well as the outline of its continuation -MTM-2 project, which aims improvement of decision making for emergency cardiac patients and usage of mHealth applications for integrated care provision in remote regions of Georgia.

The aim of this study is to evaluate the agreement between three-dimensional (3D) transesophageal echocardiography (TEE) and multidetector computed tomography (MDCT) for assessing mitral annular (MA) dimensions. A total of 105 patients (79 ± 9 years old, 52% male) who underwent clinically indicated 3D TEE and MDCT feasible for MA geometrical assessment were included. Using dedicated semi-automated postprocessing software, MA geometry, including mitral annular area (MAA), perimeter, septal-lateral (SL) diameter, and inter-trigonal (TT) diameter, was evaluated using 3D TEE and MDCT. Compared to 3D TEE, MAA, perimeter, and SL distance measured on MDCT data were larger (9.9 ± 3.0 vs. 9.3 ± 3.1 cm2 for MAA; 115 ± 18 vs. 108 ± 18 mm for perimeter; and 35 ± 5 vs. 32 ± 5 cm for SL distance, all p < 0.001). By contrast, the TT distance was comparable between MDCT and 3D TEE (26 ± 4 vs. 26 ± 4 cm, p = 0.258). The correlations of all the MA dimensions were good to excellent between the two modalities (R = 0.911 for MAA, 0.890 for perimeter, 0.739 for TT distance, and 0.857 for SL distance, respectively, all p < 0.001). This study showed good agreement between 3D TEE- and MDCT-derived MA measurements although MDCT systematically provided larger MAA, perimeter, and SL distance compared with 3D TEE.

Aims Peak left atrial longitudinal strain (PALS) is a marker of the left atrial (LA) reservoir function. Novel feature tracking (FT) software allows assessment of LA strain from multidetector computed tomography (MDCT) data. This study aimed at evaluating the agreement between speckle tracking echocardiography (STE) and FT MDCT for the measurement of PALS in patients with sinus rhythm (SR) and with atrial fibrillation (AF). Methods and results The current study included 318 patients (80 ± 7 years, 54% male) with dynamic MDCT data acquired prior to transcatheter aortic valve implantation. PALS was measured by transthoracic echocardiography using STE (PALSecho) and MDCT using dedicated FT software (PALSCT). In the overall population, the median values of PALSecho and PALSCT were 19.0 [interquartile range (IQR) 12.0–25.0] % and 15.3 (IQR 9.2–19.7) %, respectively. High correlation between PALSecho and PALSCT was observed (r = 0.789, P &lt; 0.001) with a mean bias of −3.7%. The correlation between PALSecho and PALSCT was better among patients with SR (N = 258; r = 0.704, P &lt; 0.001) as compared to patients with AF (N = 60; r = 0.622, P &lt; 0.001). Conclusion PALSecho and PALSCT showed a good agreement in patients with severe aortic stenosis (AS) regardless of the cardiac rhythm. FT MDCT may be an important adjuvant modality for assessing LA reservoir function in patients with severe AS.
