Abstract AIM Preeclampsia (PrE) is a systemic disorder unique to human pregnancy, which is characterised by hypertension and multiorgan involvement. It is associated with cardiac dysfunction with a reduction in global longitudinal strain (GLS) and long-term cardiovascular disease. The aim of this study is to evaluate the effects of the loading conditions on the GLS results utilising myocardial work (MW) a non-invasive assessment of left ventricular (LV) pressure strain loops. Methods We evaluated 41 pregnant women, aged between 18-40, at 28.4-40 (Mean 35) weeks of gestation and within one week of the diagnosis of PrE. 49 normotensive pregnant women (control) were matched for age and gestation. These patients were reassessed after six months postpartum. All patients underwent echocardiography for left ventricular indices and assessment with speckle tracking for global longitudinal strain (GLS%) and myocardial work indices - performed at both time points. Result PrE had a mean LV mass index (LVMi) of 14.53g.m2 higher than control (P value = 0.000) during pregnancy which normalised at six-months postpartum. There was a reduction in GLS between PrE and controls during pregnancy (p = 0.002) and this remained significant postpartum (p = 0.001). (Fig1) However, there was no change over time within each group. During pregnancy, peak global myocardial work efficiency (GWE%) in PrE was significantly lower than controls (p = 0.001) and no different six months postpartum (p = 0.169) (Fig2). In contrast, during pregnancy, myocardial work index (GWI mmHg) was significantly higher in PrE (p < 000) compared to control, but not in postpartum (p = 0.165) There was a significant change over time of GWI in both groups (p < 0.05) (Fig3). Conclusion During pregnancy and post-partum PrE patients show a reduction in GLS when compared to matched normotensive pregnant women. This finding is consistent with previous studies which suggests subclinical LV dysfunction in PrE. However, the GWI was significantly increased but reduced in efficiency (GWE). The GWI increase is likely a result of an increase in LV mass index. The hypertrophied LV allows the increase in work at the cost of a reduction in efficiency but normalises when the hypertrophy improves post-partum. Our study is the first to use myocardial work in PrE patients, which we believe provides a better assessment of cardiac adaptation post-partum and does not suggest long term subclinical LV dysfunction.

Background. The new coronavirus disease (COVID-19), which has arisen as a result of infection SARS-CoV-2, which causes severe respiratory syndrome, is characterized by high morbidity, mortality and is a big problem in the health sector. The aim to use 2-dimensional speckle-tracking echocardiography (STE) in combination with transthoracic echocardiography (TTE) in the assessment of left ventricular longitudinal strain (LVGLS) in pregnant women with confirmed coronavirus infection, hospitalized in the O.M. Filatov Municipal Clinical Hospital No. 15, Moscow, Russian Federation. Methods. The results of STE were analyzed in 102 pregnant women with confirmed coronavirus infection at the hospital stage of treatment. Results. There was no decrease in LVGLS values in pregnant women with COVID-19 without a history of cardiovascular pathology. There was also no additional decrease in the LVGLS value in pregnant women with COVID-19 and initially reduced LVGLS in the presence of a cardiovascular history (the results were consistent with those in pregnant women with concomitant cardiovascular pathology, but without a new coronavirus infection). Conclusions. In pregnant women with COVID-19 without a history of concomitant pathology, STE did not provide additional information regarding possible subclinical left ventricular dysfunction.

Abstract Background Left ventricular ejection fraction (LVEF) is the parameter of choice for left ventricular (LV) function assessment and risk stratification of patients with ST-elevation myocardial infarction (STEMI); however, its prognostic value is limited. Other measures of LV function such as global longitudinal strain (GLS) and mitral annular plane systolic excursion (MAPSE) might provide additional prognostic information post-STEMI. However, comprehensive investigations comparing these parameters in terms of prediction of hard clinical events following STEMI are lacking so far. Purpose We aimed to investigate the comparative prognostic value of LVEF, MAPSE and GLS by cardiac magnetic resonance (CMR) imaging in the acute stage post-STEMI for the occurrence of major adverse cardiac events (MACE). Methods This observational study included 407 consecutive acute STEMI patients treated with primary percutaneous coronary intervention (PCI). Comprehensive CMR investigations were performed 3 [interquartile range (IQR): 2–4] days after PCI to determine LVEF, GLS and MAPSE as well as myocardial infarct characteristics. Primary endpoint was the occurrence of MACE defined as composite of death, re-infarction and congestive heart failure. Results During a follow-up of 21 [IQR: 12–50] months, 40 (10%) patients experienced MACE. LVEF (p=0.005), MAPSE (p=0.001) and GLS (p<0.001) were significantly related to MACE. GLS showed the highest prognostic value with an area under the curve (AUC) of 0.71 (95% CI 0.63–0.79; p<0.001) compared to MAPSE (AUC: 0.67, 95% CI 0.58–0.75; p=0.001) and LVEF (AUC: 0.64, 95% CI 0.54–0.73; p=0.005). After multivariable analysis, GLS emerged as sole independent predictor of MACE (HR: 1.22, 95% CI 1.11–1.35; p<0.001). Of note, GLS remained associated with MACE (p<0.001) even after adjustment for infarct size and microvascular obstruction. Conclusion CMR-derived GLS emerged as strong and independent predictor of MACE after acute STEMI with additive prognostic validity to LVEF and parameters of myocardial damage.

Abstract Background Cardiac magnetic resonance feature tracking (CMR-FT) and speckle tracking echocardiography (STE) are well-established strain imaging modalities. Multilayer strain measurement permits independent assessment of endocardial and epicardial strain. This novel and layer specific approach to evaluating myocardial deformation parameters may provide greater insight into cardiac contractility when compared to whole-layer strain analysis. The aim of this study is to validate CMR-FT as a tool for multilayer strain analysis by providing a direct comparison between multilayer global longitudinal strain (GLS) values between CMR-FT and STE. Methods We studied 100 patients who had an acute myocardial infarction (AMI), who underwent CMR imaging and echocardiogram at baseline and follow-up (48 ± 13 days). Dedicated tissue tracking software was used to analyse single- and multi-layer GLS values for CMR-FT and STE. Results Correlation coefficients for CMR-FT and STE were 0.685, 0.687, and 0.660 for endocardial, epicardial, and whole-layer GLS respectively (all p < 0.001). Bland Altman analysis showed good inter-modality agreement with minimal bias. The absolute limits of agreement in our study were 6.4, 5.9, and 5.5 for endocardial, whole-layer, and epicardial GLS respectively. Absolute biases were 1.79, 0.80, and 0.98 respectively. Intraclass correlation coefficient (ICC) values showed moderate agreement with values of 0.626, 0.632, and 0.671 respectively (all p < 0.001). Conclusion There is good inter-modality agreement between CMR-FT and STE for whole-layer, endocardial, and epicardial GLS, and although values should not be used interchangeably our study demonstrates that CMR-FT is a viable imaging modality for multilayer strain

Abstract Background Atrial fibrillation (AF) impairs mechanical function of the heart, especially atria and restoration of sinus rhythm (SR) leads to improvement of mechanics. The predicting role of changes in strain parameters for AF recurrence is not established yet. Purpose To analyse changes in left atrial (LA) and left ventricular (LV) mechanical function after conversion to SR and their prognostic values for AF recurrence during 24 months follow-up. Methods Prospective study involved 59 patients after successful electrical cardioversion (EC) because of nonvalvular AF (mean age 65±4 years, 47% female). Speckle tracking analysis (STE) was applied to calculate longitudinal strain of LV and LA before EC and within 24 hours after restoration of SR and additionally total left heart strain (TS) defined as a sum of absolute peak LV and LA strain. We calculated change in strain between AF and SR analyses expressed as delta (Δ). During follow-up we noticed AF recurrence in 42 (71%) patients, most of them (93%) during 1st year after EC. Median time of AF recurrence was 3 months. Results We noticed significant immediate post-EC improvement in peak LA longitudinal strain (PALS) and LV global longitudinal strain (LVGLS) (table). Unlike CHA2DS2-VASc score, strain parameters were predictors of AF recurrence. Every 1% increment in ΔLVGLS was related with 13% increase in AF recurrence risk (p=0.02) and every 1% increment in ΔPALS and ΔTS were related with 9% decrease in AF recurrence risk (p=0.007 and p=0.0014, respectively). Multivariate analysis revealed ΔTS as a strongest predictor with 9% decrease in AF risk per every 1% increment. The criterion of ΔTS ≤7.5% allows to predict AF recurrence with 81% sensitivity and 63% specificity. Conclusions Speckle tracking measurements are able to detect early mechanical changes in LA even within 24 hours of SR and these absolute changes in LVGLS as well as PALS can predict AF recurrence, with optimal stratification by novel parameter - TS.
