Long-term cardiac effects of modern treatment for Hodgkin's lymphoma.

BACKGROUND: Hodgkin's lymphoma (HL) is a hematological malignancy that affects both children and young adults. Traditional treatment is associated with a life-time prevalence of cardiac disease exceeding 50%. In the late 1990s protocols were modified to reduce cancer therapy-related adverse cardiac effects. This study aimed to assess the long-term impact of advances in treatment protocols on the cardiac health of HL survivors (HLS). METHODS: HLS (n = 246) treated between 1997 and 2007 with anthracycline-based chemotherapy in three centers in Norway were included. Of these, 132 (53%) had also received mediastinal radiotherapy. HLS were compared to controls (n = 58) recruited from the general population and matched for sex, age, smoking status, and heredity for coronary artery disease. All subjects underwent echocardiography, clinical assessment, and blood sampling. RESULTS: The HLS were 46 ± 9 years old and had been treated 17 ± 3 years before inclusion in the study. There was no significant difference between HLS and controls in ejection fraction (EF) (58%±5 vs. 59%±4, p = 0.08) or prevalence of heart failure. HLS treated with both anthracyclines and mediastinal radiotherapy (AC + MRT) had slightly worse left ventricular global longitudinal strain than controls (-19.3 ± 2.5% vs. -20.8 ± 2.0%, p < 0.001), but those treated with only anthracyclines did not. HLS treated with AC + MRT had a higher prevalence of valve disease than those treated only with anthracyclines (12% vs. 4%, p < 0.05). CONCLUSIONS: HLS treated with anthracyclines after the late 1990s have similar cardiac function and morphology as age-matched controls, apart from higher rates of valvular disease in those who also underwent mediastinal radiotherapy.

Effects of Aerobic Exercise on Cardiorespiratory Fitness, Cardiovascular Risk Factors, and Patient-Reported Outcomes in Long-Term Breast Cancer Survivors: Protocol for a Randomized Controlled Trial.

BACKGROUND: Anthracycline-based chemotherapy has been mainstay of adjuvant breast cancer therapy for decades. Although effective, anthracyclines place long-term breast cancer survivors at risk of late effects, such as reduced cardiorespiratory fitness and increased risk of cardiovascular disease. Previous research has shown beneficial effects of exercise training on cardiorespiratory fitness, but the effects of exercise on limiting factors for cardiorespiratory fitness, cardiovascular risk factors, and patient-reported outcomes in long-term survivors are less clear. Whether previous exposure to breast cancer therapy modulates the effects of exercise is also unknown. OBJECTIVE: The primary aim of the CAUSE (Cardiovascular Survivors Exercise) trial is to examine the effect of aerobic exercise on cardiorespiratory fitness in anthracycline-treated long-term breast cancer survivors. Secondary aims are to examine effects of exercise training on limiting factors for cardiorespiratory fitness, cardiovascular risk factors, and patient-reported outcomes, and to compare baseline values and effects of exercise training between similar-aged women with and those without prior breast cancer. A third aim is to examine the 24-month postintervention effects of aerobic exercise on primary and secondary outcomes. METHODS: The CAUSE trial is a 2-armed randomized controlled trial, where 140 long-term breast cancer survivors, 8-12 years post diagnosis, are assigned to a 5-month nonlinear aerobic exercise program with 3 weekly sessions or to standard care. Seventy similar-aged women with no history of cancer will undergo the same exercise program. Cardiorespiratory fitness measured as peak oxygen consumption (VO2peak), limiting factors for VO2peak (eg, cardiac function, pulmonary function, hemoglobin mass, blood volume, and skeletal muscle characteristics), cardiovascular risk factors (eg, hypertension, diabetes, dyslipidemia, obesity, physical activity level, and smoking status), and patient-reported outcomes (eg, body image, fatigue, mental health, and health-related quality of life) will be assessed at baseline, post intervention, and 24 months post intervention. RESULTS: A total of 209 patients were included from October 2020 to August 2022, and postintervention assessments were completed in January 2023. The 24-month follow-up will be completed in February 2025. CONCLUSIONS: The findings from the CAUSE trial will provide novel scientific understanding of the potential benefits of exercise training in long-term breast cancer survivors.

Blood volume expansion does not explain the increase in peak oxygen uptake induced by 10 weeks of endurance training.

PURPOSE: The endurance training (ET)-induced increases in peak oxygen uptake ([Formula: see text]O2peak) and cardiac output ([Formula: see text]peak) during upright cycling are reversed to pre-ET levels after removing the training-induced increase in blood volume (BV). We hypothesised that ET-induced improvements in [Formula: see text]O2peak and [Formula: see text]peak are preserved following phlebotomy of the BV gained with ET during supine but not during upright cycling. Arteriovenous O2 difference (a-[Formula: see text]O2diff; [Formula: see text]O2/[Formula: see text]), cardiac dimensions and muscle morphology were studied to assess their role for the [Formula: see text]O2peak improvement. METHODS: Twelve untrained subjects ([Formula: see text]O2peak: 44 ± 6 ml kg-1 min-1) completed 10 weeks of supervised ET (3 sessions/week). Echocardiography, muscle biopsies, haemoglobin mass (Hbmass) and BV were assessed pre- and post-ET. [Formula: see text]O2peak and [Formula: see text]peak during upright and supine cycling were measured pre-ET, post-ET and immediately after Hbmass was reversed to the individual pre-ET level by phlebotomy. RESULTS: ET increased the Hbmass (3.3 ± 2.9%; P = 0.005), BV (3.7 ± 5.6%; P = 0.044) and [Formula: see text]O2peak during upright and supine cycling (11 ± 6% and 10 ± 8%, respectively; P ≤ 0.003). After phlebotomy, improvements in [Formula: see text]O2peak compared with pre-ET were preserved in both postures (11 ± 4% and 11 ± 9%; P ≤ 0.005), as was [Formula: see text]peak (9 ± 14% and 9 ± 10%; P ≤ 0.081). The increased [Formula: see text]peak and a-[Formula: see text]O2diff accounted for 70% and 30% of the [Formula: see text]O2peak improvements, respectively. Markers of mitochondrial density (CS and COX-IV; P ≤ 0.007) and left ventricular mass (P = 0.027) increased. CONCLUSION: The ET-induced increase in [Formula: see text]O2peak was preserved despite removing the increases in Hbmass and BV by phlebotomy, independent of posture. [Formula: see text]O2peak increased primarily through elevated [Formula: see text]peak but also through a widened a-[Formula: see text]O2diff, potentially mediated by cardiac remodelling and mitochondrial biogenesis.

Left Ventricular Regional Wall Motion Abnormality is a Strong Predictor of Cardiotoxicity in Breast Cancer Patients Undergoing Chemotherapy / Alteração Contrátil Segmentar Ventricular Esquerda é Preditor Independente de Cardiotoxicidade em Pacientes com Câncer de Mama em Tratamento Quimioterápico

Abstract Background: Chemotherapeutic agents of anthracyclines class and humanized monoclonal antibodies are effective treatments for breast cancer, however, they present a potential risk of cardiotoxicity. Several predictors have been recognized as predictors in the development of cardiac toxicity, and the evaluation of left ventricular segmental wall motion abnormalities (LVSWMA) has not been studied. Objective: To analyze prospectively the role of LVSWMA among echocardiographic parameters in the prediction of development of cardiotoxicity in breast cancer patients undergoing treatment with chemotherapy. Methods: Prospective cohort of patients diagnosed with breast cancer and in chemotherapy treatment with potential cardiotoxicity medications including doxorubicin and trastuzumab. Transthoracic echocardiograms including speckle tracking strain echocardiography were performed at standard times before, during and after the treatment to assess the presence (or lack thereof) of cardiotoxicity. Cardiotoxicity was defined by a 10% decrease in the left ventricular ejection fraction, on at least one echocardiogram. Multivariate logistic regression models were used to verify the predictors related to the occurrence of cardiotoxicity over time. Results: Of the 112 patients selected (mean age 51,3 ± 12,9 years), 18 participants (16.1%) had cardiotoxicity. In the multivariate analysis using the logistic regression model, those with LVWMA (OR = 6.25 [CI 95%: 1.03; 37.95], p < 0,05), LV systolic dimension (1.34 [CI 95%: 1.01; 1.79], p < 0,05) and global longitudinal strain by speckle tracking (1.48 [CI 95%: 1.02; 2.12], p < 0,05) were strongly associated with cardiotoxicity. Conclusion: In the present study, we showed that LVWMA, in addition to global longitudinal strains, were strong predictors of cardiotoxicity and could be useful in the risk stratification of these patients.

Resumo Fundamento: Os agentes quimioterápicos da classe das antraciclinas e dos anticorpos monoclonais humanizados são tratamentos eficazes para o câncer de mama, entretanto, apresentam alto risco de cardiotoxicidade. Diversos parâmetros têm sido reconhecidos como preditores no desenvolvimento de toxicidade cardíaca, sendo que a avaliação da alteração contrátil segmentar ventricular esquerda (ACSVE) ainda não foi estudada. Objetivo: Analisar a associação entre o surgimento de ACSVE e o desenvolvimento de cardiotoxicidade em pacientes com câncer de mama em tratamento com quimioterapia. Métodos: Coorte prospectiva de pacientes diagnosticados com câncer de mama e em tratamento quimioterápico com doxorrubicina e/ou trastuzumab. Foram realizados ecocardiogramas transtorácicos antes, durante e depois do tratamento para avaliar a presença ou não de cardiotoxicidade. A cardiotoxicidade foi definida por um decréscimo de 10% na fração de ejeção do ventrículo esquerdo, em pelo menos um ecocardiograma. Modelos de regressão logística multivariada foram utilizados para verificar os fatores preditores na ocorrência de cardiotoxicidade ao longo do tempo. Resultados: Dos 112 pacientes selecionados (idade média = 51,3 ± 12,9 anos), 18 (16,1%) apresentaram cardiotoxicidade. Na análise multivariada os pacientes com ACSVE (OR = 6,25 [IC 95%: 1,03; 37,95], p < 0,05), diâmetro sistólico do VE (OR = 1,34 [IC 95%:1,01; 1,79], p < 0,05) e strain longitudinal global pela técnica de speckle tracking (OR = 1,48 [IC 95%: 1,02; 2,12], p < 0,05) foram preditores significativos e independentes na predição de cardiotoxidade. Conclusão: Mostramos que ACSVE, bem como a redução do strain longitudinal global foram preditores independentes para cardiotoxicidade, podendo ser úteis na estratificação de risco destes pacientes.

Left ventricular dysfunction is related to the presence and extent of a septal flash in patients with right ventricular pacing.

Aims: Septal flash (SF), a marker of left ventricular (LV) dyssynchrony in the presence of a left bundle branch block (LBBB), has been shown to predict improved ventricular function and outcome when corrected with cardiac resynchronization therapy. We hypothesized that a SF is present in patients receiving right ventricular (RV) pacing and its presence and extent could predict the development of LV dysfunction and remodelling. Methods and Results: Seventy-four consecutive patients receiving conventional RV pacing (>6 months, >85% paced) were studied with two-dimensional (2D) echocardiography. Indications for pacing were sinus-node dysfunction and atrioventricular conduction disorders. The presence of a SF was determined on stepwise advanced 2D echocardiographic views and confirmed using greyscale M-mode. Septal flash excursion was quantified by the amplitude of the early inward motion, measured from QRS onset to maximal inward motion. Fifty-seven (of 74; 77%) patients receiving RV pacing had a detectable SF. Patients with a SF had lower LV ejection fraction (EF) (52 ± 10 vs. 60 ± 4%, P < 0.001) and greater indexed end-systolic volume (33 ± 16 vs. 23 ± 5 mL/m2, P < 0.001). Receiver operating characteristic analysis demonstrated that a SF of 3.5 mm was the optimal cut-off value (area under the curve = 0.95) to identify reduced LV function (EF < 50%) with a sensitivity of 91% and a specificity of 90%. Conclusion: A SF was present in a majority of patients receiving conventional RV pacing and its magnitude was related to LV dysfunction and adverse remodelling. Given the similarities observed in LBBB and pacemaker-induced dyssynchrony, SF magnitude might be a predictor for the development of LV dysfunction and adverse remodelling in patients receiving conventional RV pacing.

Persistence of Cardiac Remodeling in Preadolescents With Fetal Growth Restriction.

BACKGROUND: Fetal growth restriction (FGR) affects 5% to 10% of newborns and is associated with increased cardiovascular mortality in adulthood. We evaluated whether prenatal cardiovascular changes previously demonstrated in FGR persist into preadolescence. METHODS AND RESULTS: A cohort study of 58 FGR (defined as birth weight below 10th centile) and 94 normally grown fetuses identified in utero and followed-up into preadolescence (8-12 years of age) by echocardiography and 3-dimensional shape computational analysis. Compared with controls, FGR preadolescents had a different cardiac shape, with more spherical and smaller hearts. Left ventricular ejection fraction was similar among groups, whereas FGR had decreased longitudinal motion (decreased mitral annular systolic peak velocities: control median, 0.11 m/s [interquartile range, 0.09-0.12] versus FGR median 0.09 m/s [interquartile range, 0.09-0.10]; P<0.01) and impaired relaxation (isovolumic relaxation time: control, 0.21 ms [interquartile range, 0.12-0.35] versus FGR, 0.35 ms [interquartile range, 0.20-0.46]; P=0.04). Global longitudinal strain was decreased (control mean, -22.4% [SD, 1.37] versus FGR mean, -21.5% [SD, 1.16]; P<0.001) compensated by an increased circumferential strain and with a higher prevalence of postsystolic shortening in FGR as compared with controls. These differences persisted after adjustment for parental ethnicity and smoking, prenatal glucocorticoid administration, preeclampsia, gestational age at delivery, days in intensive care unit, sex, age, and body surface area at evaluation. CONCLUSIONS: This study provides evidence that cardiac remodeling induced by FGR persists until preadolescence with findings similar to those reported in their prenatal life and childhood. The findings support the hypothesis of primary cardiac programming in FGR for explaining the association between low birth weight and cardiovascular risk in adulthood.

Left atrial volumetric assessment using a novel automated framework for 3D echocardiography: a multi-centre analysis.

AIMS: This study aims at validating a software tool for automated segmentation and quantification of the left atrium (LA) from 3D echocardiography. METHODS AND RESULTS: The LA segmentation tool uses a dual-chamber model of the left side of the heart to automatically detect and track the atrio-ventricular plane and the LA endocardium in transthoracic 3D echocardiography. The tool was tested in a dataset of 121 ultrasound images from patients with several cardiovascular pathologies (in a multi-centre setting), and the resulting volumes were compared with those assessed manually by experts in a blinded analysis using conventional contouring. Bland-Altman analysis showed good agreement between the automated method and the manual references, with differences (mean ± 1.96 SD) of 0.5 ± 5.7 mL for LA minimum volume and -1.6 ± 9.7 mL for LA maximum volume (comparable to the inter-observer variability of manual tracings). The automated tool required no user interaction in 93% of the recordings, while 4% required a single click and only 2% required contour adjustments, reducing considerably the amount of time and effort required for LA volumetric analysis. CONCLUSION: The automated tool was validated in a multi-centre setting, providing quantification of the LA volume over the cardiac cycle with minimal user interaction. The results of the automated analysis were in agreement with those estimated manually by experts. This study shows that such approach has clinical utility for the assessment of the LA morphology and function, automating and facilitating the time-consuming task of analysing 3D echocardiographic recordings.

Heart morphology differences induced by intrauterine growth restriction and preterm birth measured on the ECG at preadolescent age.

Intrauterine Growth Restriction (IUGR) and premature birth are associated with higher risk of cardiovascular diseases throughout adulthood. The aim of this study was to evaluate the influence of these factors in ventricular electrical remodeling in preadolescents. Electrocardiography was performed in a cohort of 33-IUGR, 32-preterm with appropriate weight and 60 controls. Depolarization and repolarization processes were studied by means of the surface ECG, including loops and angles corresponding to QRS and T-waves. The angles between the dominant vector of QRS and the frontal plane XY were different among the study groups: controls [20.03°(10.11°-28.64°)], preterm [25.48°(19.79°-33.56°)], and IUGR [27.77°(16.59°-33.23°)]. When compared to controls, IUGR subjects also presented wider angles between the difference of QRS and T-wave dominant vectors and the XY-plane [5.28°±12.15° vs 0.49°±14.15°, p<0.05] while preterm ones showed smaller frontal QRS-T angle [4.68°(2.20°-12.89°) vs 6.57°(2.72°-11.31°), p<0.05]. Thus, electrical remodeling is present in IUGR and preterm preadolescents, and might predispose them to cardiovascular diseases in adulthood. Follow-up studies are warranted.

Left-Atrial Segmentation From 3-D Ultrasound Using B-Spline Explicit Active Surfaces With Scale Uncoupling.

Segmentation of the left atrium (LA) of the heart allows quantification of LA volume dynamics which can give insight into cardiac function. However, very little attention has been given to LA segmentation from three-dimensional (3-D) ultrasound (US), most efforts being focused on the segmentation of the left ventricle (LV). The B-spline explicit active surfaces (BEAS) framework has been shown to be a very robust and efficient methodology to perform LV segmentation. In this study, we propose an extension of the BEAS framework, introducing B-splines with uncoupled scaling. This formulation improves the shape support for less regular and more variable structures, by giving independent control over smoothness and number of control points. Semiautomatic segmentation of the LA endocardium using this framework was tested in a setup requiring little user input, on 20 volumetric sequences of echocardiographic data from healthy subjects. The segmentation results were evaluated against manual reference delineations of the LA. Relevant LA morphological and functional parameters were derived from the segmented surfaces, in order to assess the performance of the proposed method on its clinical usage. The results showed that the modified BEAS framework is capable of accurate semiautomatic LA segmentation in 3-D transthoracic US, providing reliable quantification of the LA morphology and function.

Carotid artery intima-media thickness is closely related to impaired left ventricular function in patients with coronary artery disease: a single-centre, blinded, non-randomized study.

BACKGROUND: Atherosclerosis is the underlying cause of the majority of myocardial infarctions and ischemic strokes. Carotid intima-media thickness (IMT) is a surrogate measure of atherosclerotic cardiovascular disease. Left ventricular (LV) function can be accurately assessed by 2D speckle-tracking strain echocardiography (2D-STE). The aim of this study was to assess the relationship between carotid IMT and LV dysfunction assessed by strain echocardiography in patients with coronary artery disease (CAD). METHODS: Thirty-one patients with symptoms of CAD were examined with coronary angiography, cardiac echocardiography and carotid ultrasound. Layer-specific longitudinal strains were assessed from endo-, mid- and epicardium by 2D-STE. LV global longitudinal strain (LVGLS) was averaged from 16 longitudinal LV segments in all 3 layers. LVGLS results were compared with coronary angiography findings in a receiver operating curve (ROC) to determine the cut-off for normal and pathological strain values. The calculated optimal strain value was compared to maximal carotid IMT measurements. RESULTS: The ROC analysis for strain versus coronary angiography was: area under curve (AUC)=0.91 (95% CI 0.80 - 1.0), cut-off value for endocardial LVGLS: -16.7%. Further analyses showed that increased carotid IMT correlated with low absolute strain values (p=0.006) also when adjusted for hypertension, smoking, hyperlipidemia, diabetes and BMI (p=0.02). CONCLUSIONS: In this study increased carotid IMT values were associated with decreased LV function assessed by strain measurements. These findings support the use of carotid IMT measurements to predict the risk of coronary heart disease.

Early postoperative left ventricular function by echocardiographic strain is a predictor of 1-year mortality in heart transplant recipients.

BACKGROUND: Left ventricular (LV) function can be accurately assessed using two-dimensional speckle-tracking echocardiography. The association between reduced LV global longitudinal strain (LVGLS) magnitude and risk for mortality in heart transplant recipients is unclear. The aim of this study was to test the hypothesis that LVGLS could predict 1-year mortality in heart transplant recipients. METHODS: A total of 176 consecutive adult primary single-organ orthotopic heart transplant recipients were retrospectively evaluated. Of these, 167 had acceptable echocardiographic image quality and were included in the study. N-terminal pro-B-type natriuretic peptide, creatinine, C-reactive protein, and invasive hemodynamic parameters were measured, and echocardiography was performed 1 to 3 weeks after heart transplantation. LVGLS was averaged from regional strain in 16 LV segments. RESULTS: During the first year, 15 patients (9%) died 86 ± 72 days after heart transplantation. LVGLS and LV ejection fraction were decreased in magnitude in nonsurvivors (P < .05). They were older and had higher donor ages. Mean pulmonary capillary wedge pressures were similar in the two groups, while all other hemodynamic parameters were increased in nonsurvivors (P < .05). LVGLS was the only significant (P = .02) noninvasive independent predictor, with a hazard ratio of 1.42 (95% confidence interval, 1.07-1.88; P = .02) per 1% decrease in strain magnitude, while pulmonary vascular resistance was a significant (P < .001) invasive predictor, with a hazard ratio of 3.98 (95% confidence interval, 2.01-7.87) of 1-year mortality in multivariate Cox regression analysis. CONCLUSIONS: Reduced LV function and increased pulmonary vascular resistance are related to poor prognosis in heart transplant recipients. Early assessment of LVGLS might be a noninvasive predictor of 1-year mortality in these patients.

Echocardiographic evaluation of hemodynamics in patients with decompensated systolic heart failure.

BACKGROUND: Doppler echocardiography is currently applied for the assessment of left ventricular and right ventricular hemodynamics in patients with cardiovascular disease. However, there are conflicting reports about its accuracy in patients with unstable decompensated heart failure. The objective of this study was to evaluate the accuracy of the technique in patients with unstable heart failure. METHODS AND RESULTS: Consecutive patients with decompensated heart failure had simultaneous assessment of left ventricular and right ventricular hemodynamics invasively and by Doppler echocardiography. In 79 patients, the noninvasive measurements of stroke volume (r=0.83, P<0.001), pulmonary artery systolic (r=0.83, P<0.001) and diastolic pressure (r=0.51, P=0.009), and mean right atrial pressure (r=0.85, P<0.001) all had significant correlations with invasively acquired measurements. Several Doppler indices had good accuracy in identifying patients with pulmonary capillary wedge pressure >15 mm Hg (area under the curve, 0.86 to 0.92). The recent American Society of Echocardiography/European Association of Echocardiography guidelines were highly accurate (sensitivity, 98%; specificity, 91%) in identifying patients with increased wedge pressure. In 12 repeat studies, Doppler echocardiography readily detected the changes in mean wedge pressure (r=0.75, P=0.005) as well as changes in pulmonary artery systolic pressure and mean right atrial pressure. CONCLUSIONS: Doppler echocardiography provides reliable assessment of right and left ventricular hemodynamics in patients with decompensated heart failure.
