Abstract Background Cardiac involvement is an important cause of hospitalization and mortality in patients with systemic sclerosis (SSc). Advanced echocardiographic measures such as global longitudinal strain (GLS) have already demonstrated to help identifying cardiac involvement and improve risk-stratification in these patients. However, possible sex differences in echocardiographic parameters including GLS have not been explored so far. Purpose To compare standard and advanced (GLS) echocardiographic parameters between male and female patients with SSc and evaluate their association with cardiovascular outcomes. Methods A total of 408 patients (345 females, 54±14 years old and 63 males 51±13 years old) were included in the study. The study endpoint was all-cause mortality combined with hospitalisations for heart failure, myocardial infarction, coronary interventions, device implantations, arrhythmias, cerebral infarction and peripheral ischemic disease. Results Males and females were comparable in terms of cardiovascular risk-factors and comorbidities but showed differences in terms of disease characteristics: greater modified rodnan skin score and higher creatine phosphokinase was observed in males as compared to females, although high NT-proBNP and deteriorated glomerular filtration rate was more prevalent in females. By standard echocardiography, male SSc patients were characterised by greater left ventricular (LV) volumes, but no difference was observed in LV ejection fraction. By advanced echocardiographic analysis, LV GLS was more preserved in female patients (−21% (IQR: −22% to −20%) as compared to males (−20% (IQR −21% to −19%), p<0.001. After median follow-up of 39 months (IQR: 22–66), the combined endpoint occurred in 84 patients, males were affected significantly more frequently as compared to females (20 (32%) vs. 64 (19%), p=0.017). Kaplan-Meier survival analysis showed that impaired LV GLS (based on median value −20%) was associated with higher cumulative rates of all-cause mortality both in males and females with SSc (females: Chi-Square = 80.307 Log Rank <0.001; males: Chi-Square = 4.493 Log Rank = 0.034) (Fig. 1). In univariate cox regression analyses, LV GLS was also significantly associated with the endpoint both in males and females (in males HR: 1.291, 95% CI: 1.033–1.612, p=0.025, in females HR: 1.386, 95% CI: 1.290–1.491, p<0.001). Conclusions Our study shows that among patients with SSc, LV GLS is more impaired in males as compared to females but in both groups is associated with higher prevalence of death and cardiovascular hospitalization.

Introduction: Myocarditis is an inflammatory disease process with growing clinical relevance in the current COVID-19 pandemic. Acute-phase myocarditis is known to result in subclinical changes in left ventricular (LV) function despite normal LV ejection fraction (LVEF), as assessed by myocardial deformation indices. The presence of right ventricular (RV) and left atrial (LA) subclinical dysfunction however has not been well described in current literature. Hypothesis: Myocarditis patients have subclinical impairment of LV, RV and LA function as assessed by global longitudinal strain (GLS) on speckle tracking echocardiography. Methods: Consecutive patients with clinical diagnosis of myocarditis admitted to our institution during 2013-2018 were assessed (n=76). Patients who did not meet appropriate diagnostic criteria (n=14), had impaired LVEF or prior cardiac disease (n=8) or poor transthoracic echocardiogram images (n=14) were excluded from analysis. Clinical and echocardiographic parameters were compared to age- , gender- and risk factor- matched controls. GLS was performed by two independent observers using vendor independent software (TomTec Arena, Germany v4.6). Results: The final cohort consisted 40 patients with myocarditis (age 44.3±16.7, 60% male) and 40 matched controls (44.5±16.6, 60% male). No significant differences in baseline clinical characteristics were observed between groups. No differences in LVEF, indexed LV mass, RV fractional area change, indexed LA volume or TR pressure gradient (p>0.05 for all) were demonstrated between the two groups. Patients with myocarditis had a lower mean LV strain (GLS%: -16.4±2.9 vs -19.7±2.7, p=0.0001), a lower mean RV Free Wall Strain (FWS) (GLS%: -22.1±4.1 vs -26.2±6.9, p=0.03) and a lower mean LA reservoir strain (GLS%: 27.5±4.6 vs. 33.7±6.3, p<0.0001) when compared to controls. Conclusions: Our results demonstrate the presence of significant subclinical global myocardial dysfunction despite normal traditional echocardiographic indices, in patients with acute-phase myocarditis. Routine assessment of GLS may identify such patients for early targeted cardiac therapy.

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

Abstract Background Although LV hypertrophy and dysfunction are associated with atrial fibrillation (AF), AF often occurs in the absence of LV hypertrophy or reduced ejection fraction. The effect of subclinical LV dysfunction on AF has not been fully studied. Purpose We sought the association between subclinical LV dysfunction (measured with global longitudinal strain, GLS) and new-onset AF. Methods This observational study evaluated 531 consecutive patients (median age, 67 years [interquartile range, 56 to 78]; 56% male), without a history of AF who underwent strain echocardiography after cryptogenic stroke. The CHARGE-AF score was used to calculate the 5-year risk of developing AF. Standard echocardiographic parameters were measured, and speckle-tracking was used to measure LA (reservoir strain, pump strain, and conduit strain) and LV strain (GLS). A strain analysis was conducted using a dedicated software package, using R-R gating. The baseline clinical and echocardiographic parameters of the patients who developed AF and those who did not were compared. Results Over 2.5 years of follow-up, 61 patients (11%) had new-onset AF. Patients who developed AF were older, had a higher CHARGE-AF score, larger LA volume, worse LA strain, and worse GLS than those who did not. Areas under the receiver-operating curve for GLS (0.84) was comparable to CHARGE-AF (0.79), LA pump strain (0.83), and LA reservoir strain (0.85). In the nested Cox models, GLS demonstrated an independent and incremental predictive value over the clinical and LA parameters (Figure). Moreover, adding GLS to the combined clinical and LA parameters model resulted in a significantly improved reclassification (net reclassification improvement, 0.32; p=0.016). Importantly, the predictive value of GLS was confirmed in patients with abnormal LA volumes (LA volume index≥34ml/m2) but not in patients with normal LA volumes. Figure 1 Conclusion GLS is associated with new-onset AF, especially in patients with abnormal LA volumes. This effect is independent of and incremental to the clinical and LA parameters.

Objectives: The aim of this study was to assess whether baseline echocardiographic measures of left ventricular (LV) size and function predict the development of symptomatic heart failure or cardiac death (major adverse cardiac events, MACE) in patients treated with anthracyclines who have a pre-chemotherapy left ventricular ejection fraction (LVEF) in the low normal range (between 50-59%). Background: Anthracycline-induced symptomatic heart failure and impaired LVEF are late and often irreversible manifestations of anthracycline-induced cardiotoxicity. The value of echocardiographic parameters of myocardial size and function before chemotherapy to identify patients at high-risk for development of symptomatic heart failure in patients with low normal LVEF was studied. Methods: Patients with a LVEF between 50 and 59% before anthracyclines were selected. In these patients, LV volumes, LVEF and peak longitudinal strain (GLS) were measured. Individuals were followed for MACE and all-cause mortality over a median of 659 days (range; 3-3704 days). Results: Of 2234 patients undergoing echocardiography for pre-anthracycline assessment, 158 (7%) had a resting ejection fraction of 50-59%. Their average LV end-diastolic volume (LVEDV) was 101±22ml, LVEF was 54 ±3% and global longitudinal strain (GLS) was -17.7±2.6%. Twelve patients experienced a MACE (congestive heart failure) at a median of 173 days (range; 15-530). Age, diabetes, previous coronary artery disease, LVEDV, LVESV and GLS were all-predictive of MACE (P= 0.015, 0.0043 and 0.0065 for LVEDV, LVESV, and GLS respectively). LVEDV and GLS remained predictive of MACE when adjusted for age. Age and GLS were also predictive of overall mortality (p<0.0001 and 0.0105 respectively). Conclusions: In patients treated with anthracyclines with an LVEF of 50-59%, both baseline EDV and GLS predict the occurrence of MACE. These parameters may help target patients who could bene[[Unable to Display Character: &#64257;]]t from closer cardiac surveillance and earlier initiation of cardioprotective medical therapy.

Abstract Aims The aim of present study was to examine the preoperative prevalence and distribution of impaired left ventricular global longitudinal strain (LVGLS) in elderly patients with symptomatic aortic stenosis (AS) undergoing transcutaneous aortic valve replacement (TAVR) and to determine the predictive value of LVGLS on survival. Methods We included 411 patients with symptomatic severe AS treated with TAVR during a 5-year period, where a baseline echocardiography including LVGLS assessment was available. Results Mean age was 80.1 ± 7.1 years and aortic valve area (AVA) index 0.4 ± 0.1 cm2. 78 patients died during a median follow-up of 762 days. Mean left ventricular ejection fraction (LVEF) was 50 ± 13% and mean LVGLS was − 14.0%. LVEF was preserved in 60% of patients, while impaired LVGLS > − 18% was seen in 75% of the patients. Previous myocardial infarction, LVEF < 50%, LVGLS > − 14%, low gradient AS (< 4.0 m/s), tricuspid regurgitant gradient > 30 mmHg were identified as significant univariate predictors of all-cause mortality. On multivariate analysis LVGLS > − 14% (HR 1.79 [1.02–3.14], p = 0.04) was identified as the only independent variable associated with all-cause mortality. Reduced survival was observed with an impaired LVGLS > − 14% in the total population (p < 0.002) but also in patients with high AS gradient with preserved LVEF. LVGLS provided incremental prognostic value with respect to clinical characteristics, AVA and LVEF (χ2 19.9, p = 0.006). Conclusions In patients with symptomatic AS undergoing TAVR, impaired LVGLS was highly prevalent despite preserved LVEF. LVGLS > − 14% was an independent predictor of all-cause mortality, and survival was reduced if LVGLS > − 14%.
