Abstract Background Radiotherapy is a common treatment for breast cancer, with unintended long-term CV consequences; and no consensus on adequate CV screening methods to prevent future events. We aimed to assess the use of coronary artery calcium (CAC) and left ventricular global longitudinal strain (GLS) to identify those at risk for CVD due to radiotherapy. Methods Using data from an urban cancer registry, we enrolled 17 women (mean age 62 years) with left-sided breast cancer from 1999-2003, treated with radiotherapy. Agatston CAC score was measured by CT scan; and GLS by echocardiography. Logistic regression was used to compare study CAC scores with historical controls using age- and race-matched (Multi-Ethnic Study of Atherosclerosis) MESA CAC calculator [derived from MESA cohort from 6 US communities, free of clinical CVD at baseline (2000-2002) https://www.mesa-nhlbi.org ]; and GLS with historical controls from prior meta-analysis with defined normal GLS values ( Yingchoncharoen et al). Results The Hosmer-Lemeshow goodness of fit test reported a significant lack of fit (p < 0.02) compared with the expected probability of non-zero CAC in the historical controls from MESA. The mean GLS of -20.6% (95% CI: -21.50%, -19.79%), and was not statistically different when compared with the average of the historical controls. However, there was a significant difference of GLS compared to the meta-analysis using a one-sample T test with P=0.03. Conclusion We found that women post left sided breast radiotherapy had higher CAC presence without significant difference in mean GLS, compared with historical controls from the MESA database and prior GLS meta-analysis.

Abstract Aims Myocardial work (MW) is a novel parameter that can be used in a clinical setting to assess left ventricular (LV) pressures and deformation. We sought to distinguish patterns of global MW index in hypertensive vs. non-hypertensive patients and to look at differences between categories of hypertension. Methods and results Sixty-five hypertensive patients (mean age 65 ± 13 years; 30 male) and 15 controls (mean age 38 ± 12 years; 7 male) underwent transthoracic echocardiography at rest. Hypertensive patients were subdivided into Stage 1 (n = 32) and Stage 2 (n = 33) hypertension based on 2017 American College of Cardiology guidelines. Exclusion criteria were suboptimal image quality for myocardial deformation analysis, reduced ejection fraction, valvular heart disease, intracardiac shunt, and arrhythmia. Global work index (GWI), global constructive work (GCW), global wasted work (GWW), and global work efficiency were estimated from LV pressure–strain loops utilizing proprietary software from speckle-tracking echocardiography. LV systolic and diastolic pressures were estimated using non-invasive brachial artery cuff pressure. Global longitudinal strain and LV ejection fraction were preserved between the groups with no statistically significant difference, whereas there was a statically significant difference between the control and two hypertension groups in GWI (P = 0.01), GCW (P &lt; 0.001), and GWW (P &lt; 0.001). Conclusion Non-invasive MW analysis allows better understanding of LV response under conditions of increased afterload. MW is an advanced assessment of LV systolic function in hypertension patients, giving a closer look at the relationship between LV pressure and contractility in settings of increased load dependency than LV ejection fraction and global longitudinal strain.

Background Global longitudinal strain (GLS) is recommended to detect subclinical changes preceding reduced left ventricular ejection fraction (LVEF) in trastuzumab related cardiotoxicity. The possibility to detect signs of acute myocardial deterioration at treatment initiation is not thoroughly investigated. Accordingly, the aim of this study was to assess changes in GLS and biomarkers within the first two weeks of trastuzumab treatment. Methods In a prospective cohort study 45 patients with non-metastatic breast cancer (age 54, LVEF 62.8% (SD ± 3.6), GLS -19.9% (SD ± 2.1), 40% hypertension) were included. Examinations including echocardiography and measurement of troponin T and NT-proBrain Natriuretic Peptide were conducted before initiation of trastuzumab, at day 3, 7 and 14 and after 3, 6 and 9 months. Results A significant deterioration in LVEF, GLS, s’, e’ septal and s’RV occurred during the 9 months study period and was proceed by significant changes in all these parameters within the first 14 days. After 14 days 12 patients (27%) had an increase in GLS ≥10 %, which was associated with significantly lower LVEF at nine month at 55.2% (SD ± 4.1) vs. 59.5% (SD ± 3.5) (p = 0.001) compared to patients with &lt;10 % early increase in GLS (Figure 1). No difference in plasma concentrations of cardiac biomarkers was observed between the two groups. Conclusion In this cohort study deteriorations in key echocardiographic parameters were detected within the first two weeks of trastuzumab treatment, and an early 10 % increase in GLS was associated with a lower LVEF at nine months.

Abstract Background The function of both ventricles have been suggested to be affected in patients with mitral stenosis. In this study, it was aimed to investigate deformation properties of right (RV) and left ventricles (LV) in mild and moderate rheumatic mitral stenosis (MS) patients with three-dimensional speckle tracking echocardiography (3D-STE). Methods A total of 60 patients were included in the study (20 patients with mild MS diagnosis, 20 patients with moderate MS diagnosis and 20 healthy volunteers). Three-dimensional echocardiography datasets were obtained for both ventricles in all patients. An example for RV assessment is shown in Figure 1. LV global longitudinal strain (GLS), LV torsion, RV free wall (FW) LS and interventricular septal (IVS) LS measurements were analyzed. Results The LV ejection fraction (EF), RV fractional area change and tricuspid annular plane systolic excursion values were statistically similar and in the normal range. The LV GLS measurements were significantly different among the groups by being highest in the control group and least in the moderate stenosis group (ANOVA,p &lt; 0.001) (Table 1). Patients with MS showed higher torsional values, correlated with MS severity (ANOVA,p &lt; 0.001) (Table 1). IVS LS, RVFW LS values obtained by RV analysis also differed significantly among groups. The FW-GLS values only showed significant difference between the control group and moderate MS group (Table 1). Conclusion Patients with mitral stenosis showed lower LV-GLS and higher LV torsion values. Although the LV GLS is affected; the LV EF was detected to be normal due to increase in LV torsion. RV deformation indices showed signıficant decrease in correlation with the severity of the mitral stenosis. In conclusion, our data suggest that subclinical LV and RV systolic dysfunction is present in mild-moderate MS patients and this dysfunction can be detected by 3D-STE.

COVID-19 infection can affect the cardiovascular system. We sought to determine if left ventricular global longitudinal strain (LVGLS) is affected by COVID-19 and if this has prognostic implications. Materials & methods: Retrospective study, with LVGLS was measured in 58 COVID-19 patients. Patients discharged were compared with those who died. Results: The mean LV ejection fraction (LVEF) and LVGLS for the cohort was 52.1 and -12.9 ± 4.0%, respectively. Among 30 patients with preserved LVEF(>50%), LVGLS was -15.7 ± 2.8%, which is lower than the reference mean LVGLS for a normal, healthy population. There was no significant difference in LVGLS or LVEF when comparing patients who survived to discharge or died. Conclusion: LVGLS was reduced in COVID-19 patients, although not significantly lower in those who died compared with survivors.

Abstract BACKGROUND Previous studies have shown that left ventricle global longitudinal strain (GLS) assessed with 2D-speckle tracking echocardiography, is an independent predictor of outcome in asymptomatic moderate to severe chronic aortic regurgitation (AR) patients. OBJECTIVES To assess GLS impact on mortality and need for aortic valve replacement (AVR) or symptom development in chronic asymptomatic AR patients and preserved left ventricular ejection fraction (LVEF). METHODS A literature search was performed according with these key terms "aortic regurgitation" and "longitudinal strain." The primary endpoint was all-cause mortality. Secondary end-points were: a composite of all-cause mortality, need for AVR or symptom development; and only AVR plus symptom development. Data was pooled using random-effects meta-analysis models. Pooled Hazard Ratio (HR) was performed using its log transformation and inverse variances as weights were then calculated for each study . RESULTS Six studies were included, with a total of 1,571 asymptomatic patients with at least moderate AR and preserved LVEF. There were 996 events (death, AVR, symptom development) reported during follow-up. Pooled adjusted mortality HR tended to be higher for patients with worse GLS (1.14 [0.96–1.35], P = 0.13, I2 51%). GLS performed better in predicting AVR or symptom development (mean difference -0.72 [-1.29, -0.15], P = 0.01, I2 88%), with an estimated HR of 1.36 ([1.01–1.84], P = 0.04, I2 65%). CONCLUSIONS In asymptomatic chronic moderate to severe AR patients, impaired GLS was associated with adverse cardiac outcomes. Left ventricular GLS may offer incremental value on risk stratification as well as on decision-making. Abstract P1391 Figure 1

CRA532 Background: The purpose of the study was to compare treatment outcomes in patients with breast cancer treated with partial breast irradiation and of those treated with whole breast radiation therapy. Methods: We conducted a systematic review and meta-analysis of published. Randomized clinical trials comparing partial breast irradiation versus whole breast radiation therapy. Primary outcome was overall survival and secondary outcomes were locoregional, distant and supraclavicular recurrences. Results: A search of the literature identified 3 trials with pooled total of 1,140 patients. We found no statistically significant difference between partial and whole breast radiation arms associated with death (OR 0.912, 95% CI 0.674–1.234, p = 0.550), distant metastasis (OR 0.740, 95% CI, 0.506–1.082, p = 0.120), or supraclavicular recurrences (pooled OR 1.415, 95% CI 0.278–7.202, p = 0.560). However, partial breast irradiation was statistically significantly associated with an increased risk of both local (pooled OR 2.150, 95% CI, 1.396–3.312; p = 0.001) and regional disease recurrences (pooled OR 3.430, 95% CI, 2.058–5.715; p < 0.0001) compared with whole breast radiation. Conclusions: Partial breast irradiation does not jeopardize survival and may be used as an alternative to whole breast radiation. Nevertheless, the issue of locoregional recurrence needs to be further addressed. No significant financial relationships to disclose.

Abstract Aims Global longitudinal strain (GLS) is a hallmark of cardiac damage in mitral regurgitation (MR). GLS &gt; −18% in patients with severe organic MR (OMR) and normal LV ejection fraction (LVEF) is an independent predictor of postoperative LV dysfunction. While it is known that GLS is impaired in less than severe functional ischaemic MR (FMR), the value of GLS in less than severe OMR is not known. We aimed to determine prevalence and determinants of any GLS impairment in OMR, in comparison to FMR. Methods We retrospectively evaluated 51 consecutive patients (33 OMR and 18 FMR) with mild-to-moderate, moderate and moderate-to-severe MR (Table*). Overall, GLS was higher in OMR than FMR (17.9±4.5 vs. 10.3±5.3, P&lt;0.001), with rate of impairment of 45% in OMR and 89% in FMR (P= 0.0024). Results However, no significant difference was found in GLS between mild-to-moderate, moderate and moderate-to-severe MR patients within OMR (17.7±4.7 vs. 16.9±3.9 vs. 22.4±3, respectively, P&gt;0.05), as well as FMR (9.8±6.6 vs. 10.7±5.3 vs. 10.4±5.3, respectively, P&gt;0.05) groups. GLS correlated directly with left ventricular (LV) ejection fraction (EF) in both OMR (r=0.69, P&lt;0.001) and FMR (r=0.90, P&lt;0.001), and inversely with LV mass indexed for body surface area (LVMi) in both OMR (r = −0.50, P=0.005) and FMR (r = −0.48, P=0.042). While correlation with LVEF was better for FMR than OMR (Z − 1.95, P=0.026), correlation with LVMi was similar for OMR and FMR groups (Z − 0.082, P&gt;0.05). Conclusions In patients with OMR, GLS may be reduced, despite normal LVEF, in less than severe MR. Prevalence and degree of GLS impairment in OMR is less than in FMR. In OMR, as well as in FMR, GLS impairment is independent of entity of MR, but rather correlates with LVMi, maybe reflecting impact of myocardial fibrosis derived by increased LVMi on GLS.
