Left Ventricle Segmental Longitudinal Strain and Regional Myocardial Work Index Could Help Determine Mitral Valve Prolapse Patients with Increased Risk of Ventricular Arrhythmias. J Cardiovasc Dev Dis 2023; 10:jcdd10040181. [PMID: 37103060 PMCID: PMC10145267 DOI: 10.3390/jcdd10040181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 04/11/2023] [Accepted: 04/17/2023] [Indexed: 04/28/2023] Open
Abstract
Mitral valve prolapse (MVP) could associate with malignant ventricular arrhythmias (VAs). Mitral annular disjunction, a putative mechanism for an arrhythmic substrate, leads to excessive mobility, stretch, and damage of some segments. Speckle tracking echocardiography (STE), with particular attention to the segmental longitudinal strain and myocardial work index (MWI), could be an indicator of the segments we aimed to check. Seventy-two MVP patients and twenty controls underwent echocardiography. Complex VAs documented prospectively after the enrollment was qualified as the primary endpoint, which was noticed in 29 (40%) patients. Pre-specified cut-off values for peak segmental longitudinal strain (PSS) and segmental MWI for basal lateral (-25%, 2200 mmHg%), mid-lateral (-25%, 2500 mmHg%), mid-posterior (-25%, 2400 mmHg%), and mid-inferior (-23%, 2400 mmHg%) segments were accurate predictors of complex VAs. A combination of PSS and MWI increased the probability of the endpoint, reaching the highest predictive value for the basal lateral segment: odds ratio 32.15 (3.78-273.8), p < 0.001 for PSS ≥ -25% and MWI ≥ 2200 mmHg%. STE may be a valuable tool for assessing the arrhythmic risk in MVP patients. Excessively increased segmental longitudinal strain with an augmented regional myocardial work index identifies patients with the highest risk of complex VAs.

Considering Both GLS and MD for a Prognostic Value in Non-ST-Segment Elevated Acute Coronary Artery Syndrome. Diagnostics (Basel) 2023; 13:diagnostics13040745. [PMID: 36832233 PMCID: PMC9955699 DOI: 10.3390/diagnostics13040745] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Revised: 02/06/2023] [Accepted: 02/13/2023] [Indexed: 02/18/2023] Open
Abstract
Global longitudinal strain (GLS) and mechanical dispersion (MD), as determined by 2D speckle tracking echocardiography, have been demonstrated to be reliable indicators of prognosis in a variety of cardiovascular illnesses. There are not many papers that discuss the prognostic significance of GLS and MD in a population with non-ST-segment elevated acute coronary syndrome (NSTE-ACS). Our study objective was to examine the predictive utility of the novel GLS/MD two-dimensional strain index in NSTE-ACS patients. Before discharge and four to six weeks later, echocardiography was performed on 310 consecutive hospitalized patients with NSTE-ACS and effective percutaneous coronary intervention (PCI). Cardiac mortality, malignant ventricular arrhythmia, or readmission owing to heart failure or reinfarction were the major end points. A total of 109 patients (35.16%) experienced cardiac incidents during the follow-up period (34.7 ± 8 months). The GLS/MD index at discharge was determined to be the greatest independent predictor of composite result by receiver operating characteristic analysis. The ideal cut-off value was -0.229. GLS/MD was determined to be the top independent predictor of cardiac events by multivariate Cox regression analysis. Patients with an initial GLS/MD > -0.229 that deteriorated after four to six weeks had the worst prognosis for a composite outcome, readmission, and cardiac death according to a Kaplan-Meier analysis (all p < 0.001). In conclusion, the GLS/MD ratio is a strong indicator of clinical fate in NSTE-ACS patients, especially if it is accompanied by deterioration.

Global Longitudinal Strain in Cardio-Oncology: A Review. Cancers (Basel) 2023; 15:cancers15030986.

Abstract
Several therapies used in cancer treatment are potentially cardiotoxic and may cause left ventricular (LV) dysfunction and heart failure. For decades, echocardiography has been the main modality for cardiac assessment in cancer patients, and the parameter examined in the context of cardiotoxicity was the left ventricular ejection fraction (LVEF). The assessment of the global longitudinal strain (GLS) using speckle tracking echocardiography (STE) is an emerging method for detecting and quantifying subtle disturbances in the global long-axis LV systolic function. In the latest ESC guidelines on cardio-oncology, GLS is an important element in diagnosing the cardiotoxicity of oncological therapy. A relative decrease in GLS of >15% during cancer treatment is the recommended cut-off point for suspecting subclinical cardiac dysfunction. An early diagnosis of asymptomatic cardiotoxicity allows the initiation of a cardioprotective treatment and reduces the risk of interruptions or changes in the oncological treatment in the event of LVEF deterioration, which may affect survival.

Abstract
Aim. To assess periprocedural dynamics of left ventricular ejection fraction (LVEF) in patients with first acute myocardial infarction (AMI) and percutaneous coronary intervention (PCI) without heart failure (HF) in the medical history, as well as its prognostic value in the development of cardiovascular complications in the postinfarction period.Materials and methods. A prospective, single-center observational study included 131 patients with first AMI without HF in the past medical history and successful PCI. LVEF was assessed before PCI at admission and before discharge. In patients with reduced baseline LVEF of less than 50%, the criteria for its periprocedural improvement were chosen: 1) LVEF ≥ 50%; 2) ΔLVEF of more than 5%, but EF < 50%. The endpoints were hospitalization for the development of HF and death from cardiovascular disease in combination with the development of HF. The average follow-up period was 2.5 years.Results. At admission, LVEF was < 50% in 74 (56.5%) patients. At discharge, according to the criteria for LVEF improvement, the proportion of patients in this group was 40.5 and 14.9%, respectively. In 44.6% of cases, no increase in LVEF was noted. The predictors of the absence of periprocedural dynamics in LFEF included impaired regional contractility index > 1.94, left ventricular end-systolic volume > 57 ml, left ventricular end-diastolic diameter > 5.1 cm, pulmonary artery systolic pressure >27 mm Hg, NT-proBNP > 530 pg / ml, and E / A ratio > 1.06. During the follow-up period, 28 (21.4%) patients were hospitalized for the development of HF, 33 (25.2%) patients had a combined endpoint. The absence of periprocedural improvement in left ventricular contractility was independently associated with higher odds of hospitalization for HF (relative risk (RR) 3.5; 95% confidence interval (CI) 1.63–7.55; p = 0.001) and the combined endpoint (RR 2.6; 95% CI 1.28–5.48; p = 0.009) in the postinfarction period.Conclusion. In patients with first AMI and left ventricular systolic dysfunction, periprocedural evaluation of LVEF is reasonable to stratify the risk of adverse cardiovascular outcomes.

Echocardiographic predictors of symptomatic cardiotoxicity among patients undergoing chemotherapy: A systematic review and meta-analysis. Medicine (Baltimore) 2022; 101:e29562. [PMID: 35839035 PMCID: PMC11132334 DOI: 10.1097/md.0000000000029562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Accepted: 04/21/2022] [Indexed: 10/14/2022] Open
Abstract
BACKGROUND Chemotherapeutic agents have been associated with cardiotoxicity; thus, they require close monitoring. Several echocardiographic variables have been investigated as early predictors of symptomatic cardiotoxicity in patients undergoing chemotherapy. OBJECTIVE To identify if global longitudinal strain (GLS) is a better predictor of symptomatic cardiotoxicity compared to left ventricular ejection fraction (LVEF) in patients receiving chemotherapy. METHODS MEDLINE, Scopus, and Cochrane Central Register of Controlled Trials were searched from inception through December 2020. Adults who developed symptomatic cardiotoxicity (New York Heart Association [NYHA] Class III-IV heart failure, cardiac arrest, or cardiac death) after undergoing chemotherapy with pre- and postchemotherapy echocardiographic measures of cardiac function were included. The primary focus was on the prediction of symptomatic cardiotoxicity. Estimates were reported as random effects hazard ratios (HR) with 95% confidence intervals (CI). RESULTS Four studies met inclusion criteria. The most common malignancy identified in the included studies was breast cancer, and the most common chemotherapeutic agent utilized was anthracyclines. Most studies utilized the Simpson biplane method to measure echocardiographic parameters. Pooled results demonstrated no significant association between LVEF and the prediction of symptomatic cardiotoxicity (HR 1.48; 95% CI, 0.96-2.27; P = 0.07). However, 2 studies that analyzed GLS found it to be a strong predictor of symptomatic cardiotoxicity (HR 1.46; 95% CI, 1.34-1.58; P < .001). There was no significant association between symptomatic cardiotoxicity and baseline left ventricular end diastolic volume, end systolic volume, or end diastolic volume index. CONCLUSIONS GLS may predict symptomatic cardiotoxicity and be used to monitor patients on chemotherapy for symptomatic cardiac dysfunction. While the pooled results for baseline LVEF identified that it is not a predictor of symptomatic cardiotoxicity, this differs from the findings of the only randomized trial included in this meta-analysis. The data for baseline GLS as a predictor of symptomatic cardiotoxicity is encouraging, but definite evidence that GLS may be superior to LVEF is lacking. Prospective randomized, blinded trials are required to identify if 1 echocardiographic parameter may be superior to the other.

Abstract
Fetal Heart Quantification (FetalHQ®) is a novel speckle tracking software that permits the study of global and regional ventricular shape and function from a 2D four-chamber-view loop. The 4D-Spatio Temporal Image Correlation (STIC) modality enables the offline analysis of optimized and perfectly aligned cardiac planes. We aimed to evaluate the feasibility and reproducibility of 4D-STIC speckle tracking echocardiography (STE) using FetalHQ® and to compare it to 2D STE. We conducted a prospective study including 31 low-risk singleton pregnancies between 20 and 40 weeks of gestation. Four-chamber view volumes and 2D clips were acquired with an apex pointing at 45° and with a frame rate higher than 60 Hz. Morphometric and functional echocardiography was performed by FetalHQ®. Intra- and interobserver reproducibility were evaluated by the intraclass correlation coefficient (ICC). Our results showed excellent reproducibility (ICC > 0.900) for morphometric evaluation (biventricular area, longitudinal and transverse diameters). Reproducibility was also good (ICC > 0.800) for functional evaluation (biventricular strain, Fractional Area Change, left ventricle volumes, ejection fraction and cardiac output). On the contrary, the study of the sphericity index and shortening fraction of the different ventricular segments showed lower reproducibility (ICC < 0.800). To conclude, 4D-STIC is feasible, reproducible and comparable to 2D echocardiography for the assessment of cardiac morphometry and function.

Abstract
BACKGROUND Two-dimensional speckle tracking echocardiography-derived left ventricular longitudinal systolic strain is an important myocardial deformation parameter for assessing the systolic function of the left ventricle. Strain values differ according to the vendor machine and software. This study aimed to provide normal reference values for global and regional left ventricular longitudinal systolic strain in Egyptian children using automated functional imaging software integrated into the General Electric healthcare machine and to study the correlation between the global longitudinal left ventricular systolic strain and age, body size, vital data, and some echocardiographic parameters. METHODS Healthy children (250) aged from 1 to 16 years were included. Conventional echocardiography was done to measure the left ventricular dimensions and function. Automated functional imaging was performed to measure the global and regional peak longitudinal systolic strain. RESULTS The global longitudinal strain was -21.224 ± 1.862%. The regional strain was -20.68 ± 2.11%, -21.06 ± 1.84%, and -21.86 ± 2.71% at the basal, mid, and apical segments, respectively. The mean values of the systolic longitudinal strain become significantly more negative from base to apex. Age differences were found as regard to global and regional longitudinal strain parameters but no gender differences. The global peak longitudinal systolic strain correlated positively with age. No correlations were found with either the anthropometric parameters or the vital data. CONCLUSIONS Age-specific normal values for two-dimensional speckle tracking-derived left ventricular longitudinal regional and global systolic strain are established using automated functional imaging.

Fast assessment of left ventricular systolic function in obstructive sleep apnea patients with automated function imaging: Comparison with mitral annular plane systolic excursion.

Abstract
BACKGROUND Early detection of left ventricular (LV) subclinical dysfunction is clinically relevant before developing irreversible impairment in obstructive sleep apnea (OSA) patients. Mitral annulus plane systolic excursion (MAPSE) is a fast tool for OSA due to high prevalent obesity; another quick but more comprehensive tool is LV global longitudinal stain (GLS) based on automated function imaging (AFI). We therefore aimed to compare the feasibility and reproducibility of AFI to MAPSE in OSA patients, as a good model in whom obesity is common. METHODS A comprehensive echocardiographic examination was done in 186 consecutive patients having polysomnography for suspected OSA. MAPSE was measured by using M-mode to calculate excursion of mitral annulus. GLS was derived by offline analysis of three long-axis views that semi-automatically detects LV endocardial boundary, which is adjusted manually as necessary with AFI measurement. Variability of AFI and MAPSE were compared among the different subgroups. RESULTS Despite a relatively high obesity rate (42.9%), the feasibility of AFI was 94% (175/186) and that of 100% in MAPSE. AFI showed excellent correlation (r = .882) superior to MAPSE (r = .819) between the Expert and Beginner. Intra- and inter- observer variability of AFI and MAPSE in Bland-Altman analysis were 5.5% and 6.5%; 6.2% and 8.8%, respectively. In repeated measurements, AFI showed higher intra-class correlation (ICC = .95) than MAPSE (ICC = .87) (p < 0.05). Furthermore, analysis showed that AFI was feasible even in more obese patients (BMI≥28 kg/m2 ). CONCLUSIONS Even in obese patients with OSA, AFI-GLS is feasible and more reliable for less expert operators than MAPSE in detecting LV longitudinal dysfunction.

Abstract
Hereditary hemochromatosis (HH) is a genetic disease leading to excessive iron absorption, its accumulation, and oxidative stress induction causing different organ damage, including the heart. The process of cardiac involvement is slow and lasts for years. Cardiac pathology manifests as an impaired diastolic function and cardiac hypertrophy at first and as dilatative cardiomyopathy and heart failure with time. From the moment of heart failure appearance, the prognosis is poor. Therefore, it is crucial to prevent those lesions by upfront therapy at the preclinical phase of the disease. The most useful diagnostic tool for detecting cardiac involvement is echocardiography. However, during an early phase of the disease, when patients do not present severe abnormalities in serum iron parameters and severe symptoms of other organ involvement, heart damage may be overlooked due to the lack of evident signs of cardiac dysfunction. Considerable advancement in echocardiography, with particular attention to speckle tracking echocardiography, allows detecting discrete myocardial abnormalities and planning strategy for further clinical management before the occurrence of substantial heart damage. The review aims to present the current state of knowledge concerning cardiac involvement in HH. In addition, it could help cardiologists and other physicians in their everyday practice with HH patients.

Abstract
OBJECTIVES This study sought to determine the utility of donor left ventricular function assessment by echocardiographic left ventricular global longitudinal strain (LV GLS) in predicting primary graft failure (PGF) after orthotopic heart transplantation (HT). DESIGN Retrospective, observational study. SETTING Tertiary referral hospital. PARTICIPANTS Adult patients (>18 years) who underwent isolated HT. INTERVENTIONS Demographic, clinical, and echocardiographic data were collected on 100 patients who underwent HT between January 2010 and December 2019 at the authors' institution. The respective donor variables, as well as procedural factors, were reviewed and analyzed to assess their independent association with PGF. Standard donor echocardiographic measurements were supplemented by two-dimensional speckle-tracking echocardiography to obtain LV GLS. PGF was defined as per the International Society for Heart and Lung Transplantation 2014 consensus statement. MEASUREMENTS AND MAIN RESULTS PGF occurred in 40 of the 100 patients (40%). Initial univariate analysis found that RADIAL score, donor ejection fraction, and donor LV GLS were associated with PGF. However, in a multivariate Cox regression analysis, only RADIAL score and donor LV GLS remained significant predictors of PGF, with a p < 0.001. By receiver operating characteristic curve analysis, LV GLS at a cut-off value of -11.5% showed the greatest area under the curve (area under the curve = 0.889; 95% confidence interval, 0.826-0.952) and predicted PGF with 92.5% sensitivity and 65% specificity. CONCLUSIONS Impaired donor LV GLS was proven to be an independent predictor of PGF after HT.

Abstract
BACKGROUND Diastolic dysfunction in hypertrophic cardiomyopathy (HCM) is common, but its assessment is difficult using conventional echocardiography. AIMS To assess left atrial (LA) function in HCM by longitudinal strain and determine its role in understanding of symptoms. METHODS We studied 144 patients divided into 3 age- and sex-matched groups: 48 consecutive patients with HCM, 48 control subjects, and 48 athlete subjects. We assessed LA function by conventional echocardiographic parameters and by longitudinal atrial strain (early-diastolic left atrial strain during reservoir phase [LASr]; end-diastolic left atrial strain during conduit phase; end-systolic peak of the left atrial strain during contraction phase). RESULTS NYHA classification was as follows in HCM group: I in 46%, II in 31%, III in 19%, and IV in 4%. Conventional echocardiographic parameters of diastolic function were depressed in the HCM group as compared to the control and athlete groups, but not related to symptoms. All longitudinal atrial strain parameters were significantly reduced in HCM group as compared to two groups (P < .0001). LASr was significantly correlated to peak VO2 (r = 0.44, P = .01) and was the best parameter for detecting symptomatic patients presenting with HCM, with a cutoff value of 15%: Sensitivity was 71%, specificity was 79%, PPV was 77%, and NPV was 73%. CONCLUSION Assessment of LA function in HCM is feasible using longitudinal strain, and this technique is more reliable than conventional echocardiographic parameters for the understanding of determinants of symptoms.

Detection of Early Myocardial Injury in Children with Ventricular Septal Defect Using Cardiac Troponin I and Two-Dimensional Speckle Tracking Echocardiography. Pediatr Cardiol 2020; 41:1548-1558. [PMID: 32656627 DOI: 10.1007/s00246-020-02410-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Accepted: 07/03/2020] [Indexed: 10/23/2022]
Abstract
Children with ventricular septal defects (VSDs) are subjected to hemodynamic overload which causes myocardial injury and subsequent heart failure. Early stages of myocardial damage cannot be detected by conventional echocardiography. Two-dimensional speckle tracking echocardiography (2D-STE) and cardiac troponin I (cTnI) have been recently introduced as more accurate tools for early assessment of cardiovascular diseases. The purpose of this study is to evaluate the role of cardiac troponin I (cTnI) and 2D-STE in the early detection of VSD-induced myocardial injury. Thirty children with VSD (symptomatic and asymptomatic) and 30 controls were assessed serologically by measuring serum cTnI and by conventional echocardiography. STE was performed to measure the averaged global peak longitudinal systolic stain [G peak SL(AVG)]. Serum cTnI levels were significantly higher in patients when compared to controls (P < 0.05) and in the symptomatic group when compared to the asymptomatic group (P < 0.05). Serum cTn I level correlated positively with the left atrial (r = 0.37, P = 0.045) and left ventricular dimensions (r = 0.46, P = 0.01) and negatively with the G peak SL(AVG) (r = -0.39, P = 0.03). There were no statistically significant differences between patients and controls or between symptomatic and asymptomatic groups with regard to the G peak SL(AVG). The peak longitudinal systolic strain (measured by 2D-STE) is not affected despite the elevation of serum cTnI. Serum cTnI is a sensitive marker for early detection of myocardial injury in VSD patients even before the development of ventricular dilatation or dysfunction.

Segmental longitudinal strain as the most accurate predictor of the patchy pattern late gadolinium enhancement in hypertrophic cardiomyopathy. J Cardiol 2020; 77:475-481. [PMID: 33246844 DOI: 10.1016/j.jjcc.2020.11.004] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2020] [Revised: 09/28/2020] [Accepted: 10/15/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND The prognostic value of myocardial fibrosis in patients with hypertrophic cardiomyopathy (HCM) has been well-established. Although cardiac magnetic resonance (CMR) is the method of choice in its revealing as the presence of late gadolinium enhancement (LGE), this technique still has limited availability in daily clinical practice. Two-dimensional speckle tracking echocardiography (2D STE) seems to be helpful in verification which HCM patient has the highest probability of LGE presence and hence needs to be qualified to CMR. While the majority of HCM patients have a patchy pattern of myocardial fibrosis, the aim of this study was to evaluate whether segmental rather than global longitudinal strain is more accurate in the identification of the presence of LGE. METHODS Forty-six HCM patients had transthoracic echocardiography and CMR imaging performed. Each patient had global longitudinal strain and rotation parameters calculated, as well as segmental analyses for wall thickness, longitudinal strain, and LGE presence based on 736 segments of the left ventricle (LV). The presence of LGE in CMR was confirmed on a per-segment basis, which was similar to LV segments in the echocardiographic examination. All patients were divided into two groups according to the CMR result: LGE (+) and LGE (-). RESULTS Receiver-operating characteristic analyses identified peak global longitudinal strain and peak twisting velocity with the cut-off values -14.4% and 116°/s respectively as the accurate predictors of LGE presence in CMR, whereas segmental longitudinal strain of -12.5% cut-off value had the highest area under the curve value (87.4%, confidence interval 84.5-90.3%), with 93.7% sensitivity, 86.5% negative predictive value, and 55% specificity. CONCLUSIONS Segmental longitudinal strain with the cut-off value of -12.5% has the highest discriminatory power for LGE presence and seems to be more adequate than global speckle tracking parameters in identification of HCM patients with strong indications for CMR for more accurate risk stratification.

Comparison of mitral annular displacement and global longitudinal strain imaging for predicting significant coronary atherosclerotic disease in patients of chronic stable angina pectoris. Int J Cardiovasc Imaging 2020; 37:861-870.

Abstract
Myocardial strain by two-dimensional speckle-tracking echocardiography (2D-STE) is a validated clinical index of myocardial deformation, for predicting CAD in patients with chronic stable angina pectoris (CSAP) with preserved ejection fraction (EF). However, it is complex, imaging dependant with intra and intervendor variability. The mitral annulus displacement (MAD) has been correlated to left ventricular (LV) longitudinal deformation and may be interchanged with strain imaging. This cross-sectional study was conducted on patients with suspected CSAP (n = 146) and preserved LVEF without wall motion abnormalities. We excluded patients with prior heart disease, ACS, arrhythmia, heart failure or poor imaging. GLS, Average MAD and normalized MAD were calculated using 2D-STE by automated function imaging. CAG was gold standard. MAD had significantly lesser dropout due to suboptimal imaging. Receiver operating characteristic (ROC) analysis showed that GLS had significantly better area under curve (AUC) compared to Normalised MAD and Average MAD (P = 0.035) in predicting significant CAD in patients of CSAP. The optimal cut-off of GLS, normalized MAD and Average MAD were ≥ - 20.67% (sensitivity 94.2%, specificity 86.7%), ≤ 15.22% (sensitivity 90.7%, specificity 80%) and ≤ 11.18 mm (sensitivity 83.7%, specificity 71.1%) respectively. GLS showed strong correlation with Normalised MAD (R = 0.669, P < 0.001) and good correlation to Average MAD (R 0.572, P < 0.001). Absolute GLS and Normalised MAD showed significant inverse correlation to SYNTAX score. GLS is a more accurate measure for predicting presence and severity of CAD then MAD however latter is a reliable simpler, robust, and expeditious tool with lesser dropouts. It can be at least of complementary value to other imaging markers for myocardial function when LV curvatures are poorly visualized or in busy outdoors with time constraint.

Abstract
OBJECTIVES The aim of this study was to establish multidisciplinary care for patients with transfusion-dependent thalassaemia (TDT) by creating a TDT quality improvement (QI) collaborative in a resource-constrained setting. This study presents our initial experience of creating this collaborative, the baseline characteristics of the participants, the proposed QI interventions and the outcome metrics of the collaborative. DESIGN AND SETTING TDT QI collaborative is a database comprising patients with TDT from four centres in Karachi, Pakistan. Study variables included symptoms of cardiac or endocrine dysfunction, physical examination including anthropometry and Tanner staging, chelation therapy, results of echocardiography, T2* cardiac MRI (CMR) and serum ferritin. The main outcome of this collaborative was improvement in TDT-related morbidity and mortality. Interventions addressing the key drivers of outcome were designed and implemented. RESULTS At the time of reporting, the total number of patients in this database was 295. Most patients reported cardiac symptoms corresponding to New York Heart Association class 2. Approximately half (52%, n=153) of the patients demonstrated severe myocardial iron overload (T2* <10 ms). Majority of the patients (58%, n=175) were not on adequate chelation therapy. There was no difference in echocardiographic measures of systolic and diastolic left ventricle among the different spectrums of iron overloaded myocardium. CONCLUSION Using T2* CMR and endocrine testing, we have identified significant burden of iron siderosis in our patients with TDT. Lack of adequate iron load assessment and standardised management was observed. Interventions designed to target these key drivers of outcome are the unique part of this QI-based TDT registry.

Abstract
This study examined the relationship between global longitudinal strain (GLS) and pulmonary function tests (PFT) in patients with systemic sclerosis (SS) and normal ejection fraction (EF) and pulmonary artery pressure (PAP) and healthy controls. Sixty patients in two groups underwent extensive screening, including echocardiography, physical examination, the modified Rodnan Skin Score, and pulmonary function tests. Pulmonary interstitial disease was diagnosed by the pulmonary function test and by CT scan in case of indication. GLS score was computed as the mean peak systolic strain for 17 segments. The mean GLS score was - 18.36 ± 2.1 in the case group and - 20.66 ± 1.6 in the control group (P value < 0.001). GLS scores had a significant inverse relationship with the forced expiratory volume in one second (FEV1) to forced vital capacity (FVC) ratio (P value = 0.049) and both FEV and FVC in patients younger than 35 years old (P = 0.046 and 0.049, respectively). GLS scores had no significant relationship with time elapsed since the onset of skin manifestations, and Raynaud phenomenon, Rodnan score, EF, systolic PAP, or the six-minute walk test results. The patients' six-minute walk test had a significant positive relationship with FVC and right ventricular end diastolic diameter (P value = 0.018 and 0.047, respectively). According to our findings, GLS is significantly lower in patients with SS (with normal EF & PAP) than in healthy individuals. It is also related with certain pulmonary function indices including FEV1/FVC. The reduction in GLS is associated with reduced pulmonary function strength.

Abstract
BACKGROUND Although rapid recovery of cardiac contraction is a hallmark of Takotsubo cardiomyopathy (TTC), the time course of recovery is still ill-defined. We aimed to investigate the time course of left ventricular (LV) functional recovery using 2D speckle tracking echocardiography and electrocardiography (ECG). METHODS Thirty-two consecutive patients (65 ± 16 years, 26 women) with TTC were prospectively recruited. ECG and echocardiography were performed at baseline (No. 1), before discharge (No. 2), and at 1 week (No. 3) and 5 weeks (No. 4) after discharge. Echocardiographic images and ECGs were analyzed to measure ejection fraction (LVEF), global and regional longitudinal strain (GLS, RLS), and T wave inversion (TWI) scores. RESULTS At baseline, LVEF, GLS, and TWI score were 39 ± 8.8%, -11 ± 4.3%, and 1.8 ± 3.0, respectively. Both LVEF and GLS continued to improve from baseline at the No. 2, No. 3, and No. 4 timepoints (49 ± 9.3%, 56 ± 7.5%, 58 ± 6.8%, respectively, for LVEF and -15 ± 4.2%, -17 ± 3.9%, -19 ± 3.4%, respectively, for GLS). TWI score was decreased at the No. 3 ECG relative to baseline and then increased (No. 2: -2.5 ± 3.0, No. 3: -2.9 ± 5.2, No. 4: -0.3 ± 4.4). In the apical subgroup, the reverse base-to-apex gradient of RLS had disappeared by the No. 3 echocardiography. CONCLUSIONS Contractile function as assessed by LVEF and GLS recovered continuously in patients with TTC throughout the acute and subacute phases, with rapid recovery in the acute phase. Negative T wave progressed during the acute phase and recovered more slowly during the subacute phase.

Abstract
BACKGROUND Pemphigus vulgaris which is an autoimmune dermatological disorder characterized by vesiculobullous lesions over the skin and mucosae may also give rise to cardiac disease. Global Longitudinal Strain (GLS) measurement may help to predict cardiac dysfunction in these patients. METHOD In this prospective study, the GLS was measured before and after steroid pulse therapy in pemphigus vulgaris patients using 2 D speckle-tracking echocardiography. Moreover, blood pressure, pulse rate, and corrected QT (cQT) interval were recorded before and after steroid pulse therapy. RESULTS We included 23 pemphigus patients. The mean age of patients was 34.5(±6.4). Mean GLS decreased significantly after the administration of steroid pulse therapy. The mean GLS decreased regardless of age, however, the patients with the age range of 40-50 years showed the highest change in GLS. There was no interaction between gender and GLS change. Mean cQT increased significantly after pulse therapy (p=.007). Heart rate increased significantly from 88.5 ± 10.8 to 97.0 ± 13.4 (p<.001). Mean systolic and diastolic blood pressure did not show any significant change. CONCLUSIONS The steroid pulse therapy may associate with the progression of cardiac dysfunction in pemphigus patients. GLS, as a predictor, may be a valuable marker of cardiac subclinical dysfunction in this condition.

Abstract
Background and Objectives: Patients with chronic kidney disease (CKD) exhibit a highly increased risk of cardiovascular (CV) morbidity and mortality. Subtle changes in left ventricular function can be detected by two-dimensional (2D) speckle tracking echocardiography (STE). This study investigated whether myocardial dysfunction detected by 2D STE may aid in CV and all-cause mortality risk assessment in patients with CKD stages 3 and 4. Method: A study group of 285 patients (CKD 3: 193 patients; CKD 4: 92 patients) and a healthy control group (34 participants) were included in the retrospective study. 2D STE values as well as early and late diastolic strain rates were measured in ventricular longitudinal, circumferential and radial directions. Patients’ CV and all-cause outcome was determined. Results: In the CKD group all measured longitudinal STE values and radial strain were significantly reduced compared to the control group. Cox proportional hazards regression revealed global longitudinal strain to predict CV and all-cause mortality (hazard ratio [HR] 1.15, 95% CI 1.06–1.25; p = 0.0008 and HR 1.09, 95% CI 1.04–1.14; p = 0.0003). After adjustment for sex, age, diabetes, estimated glomerular filtration rate, and preexisting CV disease, this association was maintained for CV mortality and all-cause mortality (HR 1.16, 95% CI 1.06–1.27; p = 0.0019 and HR 1.08, 95% CI 1.03–1.14; p = 0.0026, respectively). Conclusions: The present study shows that 2D STE detects reduced left ventricular myocardial function and allows the prediction of CV and all-cause mortality in patients at CKD stages 3 and 4.

Abstract
Background Coronary artery bypass graft (CABG) surgery is an effective therapeutic strategy for coronary heart disease (CHD). Myocardial longitudinal strain echocardiography with 2D speckle tracking could obtain ventricular function with better accuracy and reliability than the left ventricular ejection fraction. The aim of the study was to assess changes in left ventricular function in patients before and after surgical revascularization for a 24-month period of observation, using echocardiography with speckle tracking strain imaging. We searched for echocardiographic predictors of poor early and long-term outcome after CABG. Methods We enrolled 69 patients scheduled for elective coronary bypass grafting. Patients were divided into groups based on pre-operative systolic and diastolic parameters, depending on the GLS value and the E’ Lat and E/E’ value. The correlation between these parameters and early and long-term outcomes was analyzed. Results Preoperative EF was preserved in 86, 95% (60) patients. Pre-operative reduced GLS was observed in 73.91% (51) of patients and severely reduced in 31.88% (22). In the first post-operative 6-month period, we observed a significant decrease in the GLS. The GLS was a predictor of early postoperative outcome for intubation time, the inotropes use and length of ICU stay. Diastolic dysfunction was a predictor of the greater inotrope requirements. Conclusions Global longitudinal strain and diastolic dysfunction parameters are a good predictors of worse early outcome after CABG.

Abstract
Objectives To detect systolic dysfunction in heart failure with preserved ejection fraction (HFpEF) patients by using global longitudinal strain (GLS). Methods This study included 46 heart failure patients: 24 with heart failure with reduced ejection fraction (HFrEF) and 22 with heart failure with preserved ejection fraction (HFpEF), and 20 patients with similar risk factor but no symptoms or signs of heart failure, matched for age and sex, as controls. All patients were screened by echocardiography. The ejection fraction of left ventricle was measured using Simpson’s method and the GLS of the left ventricle was measured by using two-dimensional speckle tracking. Results Left ventricular ejection fraction (LVEF) was 61.90 ± 2.94% in the controls, 60.45 ± 7.4% in the HFpEF group (p = 0.421), and 32.75 ± 8.45% in the HFrEF group (p = 0.001). The value of left ventricle (LV) GLS (controls = −19.74 ± 1.12%, HFpEF = −15.03 ± 2.03%, HFrEF = −10.72 ± 1.99%, p = 0.0001) was significantly impaired in the HFpEF group despite normal LVEF. Conclusion There is significant left ventricular systolic impairment detected by GLS despite preserved LVEF.

Abstract
Introduction: Systemic lupus erythematosus (SLE) myocarditis occurs in between 5% and 10%
of patients with lupus. Global longitudinal strain (GLS) via speckle tracking echocardiography
can detect cardiac involvement in patients suffering from SLE. We decided to determine the
echocardiographic features and subsequent early diagnosis of cardiac involvement in patients
with SLE utilizing the GLS index via speckle tracking echocardiography.
Methods: In this cross-sectional study, we compared female patients with SLE of at least 2 years’
duration and healthy controls in terms of the left ventricular (LV) GLS via speckle tracking
echocardiography. After data collection in both groups, the GLS index and the ejection fraction
were evaluated.
Results: We analyzed and compared the LV echocardiographic parameters of 33 patients with
SLE (mean age=25.45±0.63 years) with those of 35 healthy controls (mean age=27±0.45 years).
The apical 2-chamber view indicated a significant decrease in the LV GLS in the case group by
comparison with the healthy controls (P=0.005). The LV GLS in the apical 3-chamber view was
significantly lower in the case group than in the control group (P=0.006). The LV GLS in the
apical 4-chamber view revealed no significant difference between the case and healthy control
groups (P=0.2). While there was a significant difference between the case and control groups visà-
vis the LV GLS (P=0.02), the LV ejection fraction measured with the Simpson method showed
no significant difference between the 2 groups (P=0.96).
Conclusion: GLS speckle tracking echocardiography is a noninvasive method with diagnostic and
prognostic values; it may, therefore, be a sensitive marker for the diagnosis of myocarditis and
other cardiac involvements in patients with SLE.

Abstract
BACKGROUND Cirrhosis is associated with morpho-functional cardiovascular alterations. AIMS To detect early features of cardiovascular damage in HCV-compensated cirrhotic patients using myocardial deformation indices and carotid arterial stiffness, and, further, to evaluate their short-term behaviour after HCV eradication with direct antiviral agents (DAAs). METHODS Thirty-nine consecutive patients with HCV cirrhosis, without previous cardiovascular events, were studied and matched for age, gender and cardiovascular risk factors to 39 controls without liver or cardiovascular disease. Patients and controls underwent a baseline echocardiographic evaluation including global longitudinal strain and ultrasound scan of carotid arteries. HCV-cirrhotics were reassessed by echocardiography and carotid ultrasound after obtaining sustained virological response (SVR) on DAAs. RESULTS HCV-cirrhotics showed at baseline a significantly reduced global longitudinal strain compared to controls -18.1 (16.3-20.5) vs -21.2 (20.4-22.3), P < 0.001. They also had a significantly higher pulse wave velocity 8.6 (7.7-9.1) m/s vs 6.6 (6.0-7.1) m/s, P = 0.0001, and β-stiffness index 12.4 (11.1-13.5) vs 8.6 (8.0-9.2) P = 0.0001. At multiple regression analysis, diabetes and HCV cirrhosis were independent predictors of global longitudinal strain. All HCV-cirrhotic patients had SVR on DAAs. Follow-up available in 32 of 39 (82%) at 9 (8-10) months showed a significant improvement of tricuspid annular plane systolic excursion (P = 0.01) and lateral E' velocity compared to baseline (P = 0.001). CONCLUSIONS HCV-cirrhotics show a significant rate of subclinical cardiac and vascular abnormalities. At a time when their survival is less linked to progression of liver disease, due to viral eradication on DAAs, cardiovascular morbidity and mortality may take a significant role.

Abstract
INTRODUCTION Pre-eclampsia is a common disorder associated with serious maternal and fetal complications. It is associated with abnormal placentation, which significantly reduces flow, resulting in a relative hypoxic state. These pathophysiological changes lead to subtle macrovascular and cardiac structural and functional changes in the fetus. This can predispose the child with maternal history of pre-eclampsia to risk of premature cardiovascular disease. METHODS AND ANALYSIS The children will be identified from a cohort of women with pre-eclampsia. The study will be conducted at The Aga Khan University Hospital, Karachi. Inclusion criteria will be children who are between 2 and 5 years of age and have a maternal history of pre-eclampsia. The child's current weight, height and blood pressure will be recorded. A two-dimensional functional echocardiogram and vascular assessment will be performed to evaluate alterations in cardiac function as well as macrovascular remodelling in these children. Data will be presented as mean±SD, median (IQR) or percentages as appropriate. Independent t-test or Mann-Whitney U test will be used for testing of continuous variables (based on the assumption of normality). A p<0.05 will be used to determine statistical significance. ETHICS AND DISSEMINATION Ethical approval has been obtained from AKUH Ethics Review Committee. Findings will be disseminated through scientific publications and project summaries for the participants.

Abstract
BACKGROUND The biplane Simpson's method is considered the gold standard to assess and monitor left ventricular (LV) ejection fraction (EF) in critically ill patients. Recently, a new semi-automatic technique based on speckle tracking echocardiography called "Auto-EF" has been introduced. We compared LVEF values obtained with biplane Simpson's method and Auto-EF by two groups of operators: trainee echocardiography intensivists and experienced echocardiographers. METHODS A standard transthoracic echocardiography was performed on 37 patients. According to image quality 29 patients were selected. Each inexperienced and experienced operator executed an off-line analysis using both Simpson's method and Auto-EF. LVEF obtained by the two groups of operators were then compared. RESULTS EF values assessed with Simpson's method showed a moderate correlation (r=0.70, P<0.01) between inexperienced and experienced operators. The Bland-Altman analysis showed a mean bias of 0.3% with limits of agreement (LoA) from -24.4 to +25.1%. Values obtained with Auto-EF showed a good correlation (r=0.94, P<0.01) with a mean bias of 0.2% and LoA from -10.1 to +10.4%. CONCLUSIONS Due to its semiautomatic nature, for inexpert operators Auto-EF seems more reproducible than the traditional Simpson's method for monitoring left ventricular function in critically ill patients.

Abstract
BACKGROUND Two-dimensional speckle strain (2D STE) echocardiography can aid in the prognosis of acute myocardial infarction (AMI) and chronic coronary artery disease (CAD). HYPOTHESIS Differences occur in the prediction of cardiac events using 2D STE in AMI vs CAD patients. METHODS In this prospective study, 94 patients with a first AMI and successful revascularization, and 137 patients with stable CAD after complete revascularization were included. In all patients, we performed echocardiography and myocardial deformation analysis for layer-specific global circumferential strain (GCS) and longitudinal strain. Receiver operating characteristic (ROC) curve analysis was used to predict the presence of a cardiac event using strain values and baseline characteristics in different regression models. RESULTS Patients were followed for 3.6 ± 0.8 years. Strain parameters in AMI and CAD patients were significantly different with respect to the occurrence of a cardiac event. Frequency of diabetes and hypertension was associated with the presence of a cardiac event in CAD patients. Furthermore, in CAD patients, ROC analysis demonstrated that the addition of endocardial GCS to baseline characteristics and ejection fraction to a regression model significantly improved the prediction of cardiac events (area under curve = 0.86, cutoff value: 20%, sensitivity: 79%, specificity: 84%). In contrast, the addition of strain parameters in AMI patients did not increase the prediction power for cardiac events. CONCLUSIONS Global strain parameters by 2D STE may be useful for the prediction of cardiac events in patients with CAD but add no supplemental information to baseline characteristic and ejection fraction in patients with AMI.

Detection of Acute Changes in Left Ventricular Function by Myocardial Deformation Analysis after Excessive Alcohol Ingestion. J Am Soc Echocardiogr 2018; 30:235-243.e1.

Abstract
BACKGROUND The effects of acute excessive alcohol ingestion on echocardiographic parameters of left ventricular (LV) function are unclear. METHODS One hundred ninety-nine healthy subjects (44 ± 5 years, 71% male) were prospectively examined within 6 hours after excessive alcohol ingestion as well as after 4 weeks with strict alcohol abstinence. Echocardiography was performed at baseline and follow-up for conventional parameters (left ventricular ejection fraction [LVEF], transmitral E and A Doppler flow velocities, E/A ratio, tissue Doppler velocity lateral and septal (é), E/é ratio, deceleration time of E, and isovolumic relaxation time) and myocardial deformation data (such as global radial and global and layer-specific circumferential [endo and epi global CS] and longitudinal [endo and epi global LS] strain). Multivariate regression was used to assess the impact of independent variables on echocardiographic parameters. RESULTS Alcohol levels were 1.2 ± 0.3 g/L at the time of drinking cessation. After alcohol ingestion endo CS (30% ± 2% vs 37% ± 3%, P = .008) and endo LS (27% ± 4% vs 33% ± 3%, P = .002) were significantly lower at baseline versus follow-up. Blood pressure, LVEF and heart rate, and other echocardiographic parameters did not differ between the two examinations. Alcohol levels were modestly, negatively associated with change in endo CS and endo LS (r = -0.54, 95% CI, -0.63 to -0.43, P < .001; and r = -0.26, 95% CI, -0.39 to -0.14; P < .003, respectively). Alcohol levels were the strongest predictor for endo CS (β = -4.84; 95% CI, -6.31 to -3.37) and endo LS (β = -2.50; 95% CI, -4.32 to -0.68). CONCLUSIONS Acute alcohol ingestion effects endocardial CS and LS, suggesting an acute and transient toxic effect on myocardial deformation, an effect that remains undetected by conventional echocardiographic parameters. The current findings may help clinicians to gain more understanding into the mechanism of developing an alcohol cardiomyopathy and to detect early persistent alcohol-induced myocardial disturbances for an effective therapy in time to prevent harm.

Abstract
INTRODUCTION Left ventricular (LV) dysfunction is a major prognostic determinant in myotonic dystrophy type 1 (DM1). Therefore, markers of early-stage LV impairment may be useful. The aim of this study was to evaluate 2D echocardiographic LV strain in a cohort of DM1 patients with preserved left ventricular ejection fraction (LVEF) and to compare the results with matched controls. METHODS This prospective single-center study included 33 consecutive DM1 patients between February 2014 and February 2015. Mean age was 38.2±12.9 years, and 17 (52%) were males. Exclusion criteria were LVEF <55%, QRS >120 milliseconds, history of atrial fibrillation, and presence of a pacemaker with ventricular pacing. DM1 patients were matched to healthy controls according to sex and age. RESULTS DM1 patients showed significant impairment of global longitudinal strain (GLS) as compared to controls (-18.0±1.9 vs -19.1±2.4; P=.03), characterized by a marked alteration at the apex (-20.0±3.3 vs -22.7±3.1; P<.001). DM1 patients had also global radial strain impairment (20.0±9.8 vs 27.5±14.9; P=.024) compared to controls while global circumferential strain was not statistically different between groups (P=.94). Intra- and inter-observer analysis showed good reproducibility of GLS. CONCLUSION Despite preserved LVEF, DM1 patients exhibited significantly altered LV GLS, particularly at the apex, as compared with controls. The detection of impaired myocardial deformation at early stages of the disease might help to screen high-risk patients who need closer follow-up.

Abstract
INTRODUCTION Although global deformation parameters have been increasingly used for myocardial function analysis, there are sparse data concerning segmental deformation of the left ventricle (LV). Moreover, some studies suggest heterogeneity of strain among LV segments, which may be especially significant during stress echocardiography. We assessed quantitatively regional LV function in the setting of dobutamine stress echocardiography (DSE), to examine differences of longitudinal strain between basal, mid and apical LV segments and to compare variability of regional deformation between rest and the peak stage of DSE. MATERIAL AND METHODS Among 250 patients examined by DSE applied for diagnosis of ischemia, a subset of 111 patients without significant coronary stenoses in angiography was selected (68 females, mean age: 60 ±10 years). Systolic longitudinal strain (SLS) in individual LV segments at baseline and the peak stage of DSE was analyzed with speckle tracking echocardiography. RESULTS Inhomogeneity of SLS among the LV segments (p < 0.001) was observed at baseline and the peak stage. Dispersion indices were higher at the peak stage of DSE than at baseline (p < 0.001), and the lowest heterogeneity was observed among mid segments. The analysis of changes in SLS during DSE showed SLS reduction in basal and mid-ventricular segments and an increase in apical segments. CONCLUSIONS Significant heterogeneity of strain and the opposite direction of the longitudinal strain changes during DSE between apical and basal LV segments were observed. This variability among non-ischemic LV segments ought to be considered in quantification of LV function during DSE.

Abstract
Objective: Impairment in left ventricular (LV) function due to excessive ventricular extrasystoles (VESs) occurs during long-time follow-up. Speckle tracking echocardiography (STE) has been shown to be superior to conventional methods for evaluating cardiac functions. We aimed to use STE for early detection of LV dysfunction in patients with apparently normal hearts who have frequent VESs. Methods: Fifty-five patients with frequent VESs were identified according to the Lown classification (Grade 2; unifocal more than 30 times in 1 h). Subjects aged 22-60 years with frequent VESs that had been detected for at least 1 year were included in the study according to the inclusion criteria. Forty-five subjects with similar demographic characteristics, but without VESs, were included as the control group. All participants were evaluated by STE. Results: Fifty-five patients with frequent VESs (mean age 47 years, range 22-60 years; 42.2% male) and 45 control subjects (mean age 46 years, range 22–60 years; 37.8% male) were enrolled in the study. Global LV longitudinal strain (GLS) was decreased in patients with frequent VESs (-18.41±3.37 and -21.82±2.43; p<0.001). In addition, global LV circumferential strain was decreased in patients with frequent VESs (-16.83±6.06, -20.51±6.02; p<0.001). The frequency and exposure time of VESs were negatively correlated with GLS (r=-0.398, p<0.001; r=-0.191, p=0.001, respectively). Conclusion: STE revealed that LV functions were decreased in patients with VESs. This deterioration increased with the frequency and exposure time of VESs. Impairment of LV function due to excessive VESs occurs during long-time follow-up. STE may be used for early detection of LV dysfunction.

Abstract
Speckle tracking global longitudinal strain (GLS) from dobutamine stress echocardiography (SE) predicts coronary artery disease (CAD). The diagnostic value of GLS from vasodilator SE and the additional value of layer-specific speckle tracking analysis are unclear. We explored the usefulness of layer-specific GLS and non-layer-specific strain (automated functional imaging, AFI) from adenosine SE. The included 132 patients (67% male, 62.6 (9.0) years), of which 46 (35%) had CAD defined as ≥1 stenosis ≥70% (≥50% in the left main), underwent adenosine SE and invasive coronary angiography. Resting AFI and layer-specific GLS were similar in patients with or without CAD (p > 0.05). The stress-rest difference (Δvalue = stress-value - rest-value) in patients with CAD was less pronounced compared to patients without proved CAD (Δendocardial GLS: -1.2 (3.5)% vs. -5.0 (3.2)%; Δmidventricular GLS: -0.95 (3.0)% vs. -4.2 (2.7)%; Δepicardial GLS: -0.7 (2.5)% vs. -3.4 (2.3)%; ΔAFI: -0.8 (2.9)% vs. -3.6 (3.1)%, p < 0.00001 for all comparisons). The diagnostic value of the three layer-specific GLS values and AFI were statistically similar (p = 0.19). The four Δvalues provided independent predictive value to the risk assessment given by gender, age, wall motion and ΔEF (p = 0.002, AFI and p < 0.0001, layer-specific GLS). The accuracies were acceptable (71-80%) with modest sensitivities (54-65%) and high specificities (80-91%). The deformation response to vasodilator infusion was associated with the presence of CAD. Endocardial, midventricular and epicardial GLS and AFI from adenosine SE had similar diagnostic values. The specificities were high, but the modest sensitivities are a limitation to the clinical application.

Abstract
Herceptin (Trastuzumab) is a widely used and effective drug for the treatment of Her2+ breast cancer but its cardiotoxic side effects require regular monitoring by echocardiography. A 10% reduction in left ventricular ejection fraction can lead to suspension of treatment and therefore has significant implications for patient prognosis in terms of cardiac and cancer outcomes. Assessment of LV function by conventional 2D biplane method of discs (2DEF) has limitations in accuracy and reproducibility. Global longitudinal strain (GLS) is becoming more widely available and user friendly. It has been shown to demonstrate myocardial damage earlier in treatment than 2DEF, allowing the option of pharmacological intervention at a pre-clinical stage and preventing the interruption of Herceptin. This study compares the reproducibility of GLS with that of 2DEF in a routine clinical environment. Fifty echocardiograms performed on female patients undergoing Herceptin treatment were used to measure both 2DEF and GLS within the recommended standard appointment time of 40 min. The data were re-measured (blind) by the same operator a minimum of 14 days later to determine intra-operator variation. These data were also measured by a second operator (blind), to assess inter-operator variation. Analysis by direct comparison, intra-class correlation (ICC), coefficient of variation (CV) and Bland–Altman plots demonstrated that GLS is a more reproducible measurement than 2DEF. This is important to prevent clinical decisions being erroneously based on variation in operator measurement. The investigation also shows that with advances in machine software this is a practical addition to routine assessment rather than merely a research tool.

Abstract
BACKGROUND Cardiac magnetic resonance imaging (CMR) has been established as a powerful tool for predicting mortality. However, its application is limited by availability and various contraindications. The aim of this study was to evaluate the predictive value of layer-specific myocardial deformation analysis as assessed by strain echocardiography for cardiac events in patients with chronic ischemic left ventricular dysfunction in comparison with CMR. METHODS Three hundred ninety patients (mean age, 63 ± 4 years; 69% men; mean left ventricular ejection fraction [LVEF], 41 ± 7%) with chronic ischemic cardiomyopathy were prospectively enrolled and underwent strain echocardiography and CMR within 3 ± 1 days. LVEF, wall motion score index, and circumferential strain (CS), longitudinal strain, and radial strain for total wall thickness and for three myocardial layers (endocardial, midmyocardial, and epicardial) were determined by echocardiography. The extent of total myocardial scar (TMS) was determined by CMR. Follow-up was obtained for a mean of 4.9 ± 2.2 years. Cardiac events were defined as readmission for worsening of heart failure, ventricular arrhythmias, or death of any cause. The incremental value of LVEF, strain parameters, and TMS to relevant clinical variables was determined in nested Cox models. RESULTS There were 133 cardiac events (34%). Baseline clinical data associated with outcomes were age (hazard ratio [HR], 1.27; P = .04), diabetes mellitus (HR, 1.52; P = .001), and renal insufficiency (HR, 1.77; P = .001) by multivariate analysis. The addition of LVEF, global and endocardial strain parameters, and TMS increased the predictive power, but endocardial CS (HR, 1.52; P < .01) caused the greatest increment in model power (χ(2) = 39.2, P < .001). Endocardial CS < -20% was found to be the optimal predictor of prognosis. CONCLUSIONS Endocardial CS is a powerful predictor of cardiac events and appears to be a better parameter than LVEF, TMS by CMR, and other strain variables by echocardiography.

Abstract
Previous studies have noted reversible cardiac dysfunction during marathon races, but few data are available concerning ultradistance trail running. The aim of this study was to assess echocardiographic parameters during ultradistance trail running. We performed an observational study in 66 participants to the 80-km Ecotrail of Paris Ile de France. All subjects had echocardiographic examinations before the race and on arrival, and 28 of them underwent serial echocardiographic examinations during the race (21 and 53 km). A single experienced physician performed all echocardiographic examinations, and the same protocol was always used (conventional 2-dimensional and Doppler left ventricular parameters and longitudinal strain). All echocardiographic parameters of left ventricular (LV) systolic function were significantly decreased on arrival (p ≤0.002). A significant reduction of LV systolic function was observed in 48% of study subjects on arrival. No significant modification was observed at 21 or at 53 km, and only global longitudinal strain was significantly decreased (p = 0.0008). At arrival, mitral E/A ratio and average mitral tissue Doppler imaging e' wave were significantly decreased (p = 0.0001 and p = 0.0004, respectively), but these changes were observed from 21 km. In conclusion, ultradistance trail running can lead to abnormalities of LV systolic and diastolic functions in amateur runners. Diastolic dysfunction arises earlier than systolic dysfunction. Left ventricular systolic dysfunction occurred in 48% of the study subjects and was detected early by assessment of longitudinal strain.

Abstract
Myocardium viability in ischemic heart failure (HF) may affect the effect of cardiac resynchronization therapy (CRT). We hypothesized that longitudinal strain of 2D-STE, which reflects myocardium viability, can predict the response to CRT in patients with ischemic HF. 2D-STE was performed in 42 patients with HF, 1 week before and 1 year after CRT. GLS, RLS, and the LV synchrony index (SI), defined as the difference in timing to peak radial strain between LV anterior septal and posterior wall in LV short axis view, were calculated. A decrease in the LV end-systolic volume (LVESV) value of ≥ 15 % 1 year after CRT was defined as response to CRT. Twenty-nine patients responded to CRT (CRT-R group), while 13 patients did not respond and were assigned as CRT-NR group. Pre-CRT RLS and GLS were higher, while SI is lower, in CRT-R patients compared with CRT-NR group (p < 0.001). The ROC curve revealed that RLS of -11.5 % predicted response to CRT with sensitivity of 80.0 % and specificity of 77.9 % (AUC = 0.84, p < 0.001). Further, GLS of -13 % predicted response to CRT with sensitivity of 73.0 % and specificity of 73.4 % (AUC = 0.79, p < 0.001). In conclusion, LV dyssynchrony, GLS, and RLS calculated by 2D-STE can predict long-term response to CRT in patients with ischemic HF.
