Serial echocardiographic assessment of left ventricular ejection fraction (LVEF) is the gold standard in screening for chemotherapy-induced cardiotoxicity (CIC). Measurement of myocardial deformation using speckle tracking enables more detailed assessment of myocardial contractility. The aim of this study was to determine the relationship between global and regional longitudinal strain and CIC. This was a prospective study of 158 breast cancer patients undergoing chemotherapy with anthracyclines with or without adjuvant trastuzumab who underwent serial monitoring by transthoracic echocardiography with assessment of myocardial deformation. CIC was defined as a decrease in LVEF to <53%. Global longitudinal strain (GLS) was estimated using EchoPAC BT12 software on a GE Vivid E9 cardiac ultrasound system. Patients were classified according to the 2015 ASE/EACVI criteria as having impaired myocardial deformation when GLS was reduced (less negative), with a cutoff of -18%. During a mea...
Myocardial Work Brings New Insights into Left Ventricular Remodelling in Cardio-Oncology Patients
International Journal of Environmental Research and Public Health, 2022
Serial transthoracic echocardiographic (TTE) assessment of 2D left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) are the gold standard screening methods for cancer therapeutics-related cardiac dysfunction (CTRCD). Non-invasive left ventricular (LV) pressure-strain loop (PSL) provides a novel method of quantifying myocardial work (MW) with potential advantages to evaluate the impact of cardiotoxic treatments on heart function. We prospectively assessed breast cancer female patients undergoing cancer therapy through serial monitoring by 2D and 3D TTE. Patients were evaluated at T0, T1 and T2 (before, 4–6 and 12–14 months after starting therapy, respectively). Through PSL analysis, MW indices were calculated. A total of 122 patients, with a mean age of 54.7 years, who received treatment with anthracyclines (77.0%) and anti-HER2 (75.4%) were included. During a mean follow-up of 14.9 ± 9.3 months, LVEF and GLS were significantly diminished, and 29.5% developed...

Objective-The objective of this study was to determine the relationships between echocardiography-derived measures of myocardial mechanics and cancer therapeutics-related cardiac dysfunction (CTRCD). Background-Doxorubicin and trastuzumab are highly effective breast cancer therapies, but have a substantial risk of CTRCD. There is a critical need for the early detection of patients at increased risk of toxicity. Methods-We performed a prospective, longitudinal cohort study of breast cancer participants undergoing doxorubicin and/or trastuzumab therapy. Echocardiography was performed prior to therapy initiation (baseline) and at standardized follow-up intervals during and after completion of therapy. Ejection fraction (EF), strain, strain rate, and ventricular-arterial coupling (Ea/Ees sb) were

Background: Chemotherapy-induced cardiotoxicity has not been extensively validated in bone marrow transplantation (BMT) patients. Speckle-tracking echocardiography is a sensitive method for the detection of subclinical cardiac dysfunction. Methods: Cardiac function was prospectively assessed in 80 patients (44 men; mean age, 45 6 11 years) after BMT for non-Hodgkin's lymphoma and acute or chronic myeloid leukemia by means of various echocardiographic techniques. Before chemotherapy for BMT, 89% of the patients had previously been treated with anthracyclines. Patients had normal left ventricular ejection fraction (LVEF). Left ventricular (LV) global longitudinal strain (GLS), subendocardial and subepicardial longitudinal strain, circumferential strain, LV twist, and right ventricular GLS were measured by speckle-tracking, and (2) three-dimensionally derived LVEF and right ventricular ejection fraction were also assessed. Abnormal LVEF was defined as <53%. Studies were performed before (baseline) and 1, 3, 6, and 12 months after chemotherapy conditioning followed by BMT. Results: Impaired LV GLS values were observed at 1 month after chemotherapy and at 3, 6, and 12 months compared with baseline (À20 6 2.2% at baseline, À18.4 6 2.1% at 1 month, À17.3 6 2.2% at 3 months, À17.1 6 2.1% at 6 months, and À17.1 6 2.2% at 12 months; P = .001). Early LV GLS changes were driven mostly by changes in subendocardial longitudinal strain (À22.5 6 2.4% at baseline, À20.5 6 2.3% at 1 month, À19.2 6 2.3% at 3 months, À19.2 6 2.4% at 6 months, and À19.1 6 2.4 at 12 months; P = .001), whereas significant subepicardial strain changes were observed at 3 months after BMT. Compared with baseline, right ventricular GLS was also impaired early after chemotherapy. Compared with baseline, LVEF was slightly reduced (P = .02) at the end of the follow-up. Among echocardiographic markers, LV GLS at 1 month had the strongest predictive value for abnormal LVEF (<53%) at 12 months (area under the curve 0.86; 95% CI, 0.76-0.96). A cutoff LV GLS value of À18.4% had sensitivity of 84.6% and specificity of 71.9% for the identification of abnormal LVEF at the end of follow-up. Conclusions: In BMT patients, myocardial deformation analysis detected early and progressive subclinical cardiac dysfunction. Impaired LV GLS had predictive value for the detection of abnormal LVEF at 12-month follow-up. Thus, myocardial deformation study should be applied early after BMT to prevent irreversible cardiac dysfunction by appropriate treatment.

Trastuzumab, a HER2 monoclonal antibody, has transformed the prognosis of patients with the aggressive HER2-positive breast cancer type. Trastuzumab augments the cardiotoxic effects of anthracyclines, but its effect is thought to be at least partially reversible. The objective of this study was to examine the time trends of left ventricular (LV) size and function in a cohort of women treated with anthracyclines and trastuzumab. Twenty-nine patients >18 years of age with first-time breast cancer treated with anthracyclines and trastuzumab were monitored using echocardiography before, at the completion of, and at a median follow-up of 24.7 months (interquartile range, 15.9-34 months) after the end of their cancer treatment. LV volume, LV ejection fraction, and global peak systolic longitudinal strain and strain rate were measured in the apical four- and two-chamber views. Left ventricular ejection fraction was measured using a modified Simpson's biplane method. LV end-diastolic...

Background-Because cancer patients survive longer, the impact of cardiotoxicity associated with the use of cancer treatments escalates. The present study investigates whether early alterations of myocardial strain and blood biomarkers predict incident cardiotoxicity in patients with breast cancer during treatment with anthracyclines, taxanes, and trastuzumab. Methods and Results-Eighty-one women with newly diagnosed human epidermal growth factor receptor 2-positive breast cancer, treated with anthracyclines followed by taxanes and trastuzumab were enrolled to be evaluated every 3 months during their cancer therapy (total of 15 months) using echocardiograms and blood samples. Left ventricular ejection fraction, peak systolic longitudinal, radial, and circumferential myocardial strain were calculated. Ultrasensitive troponin I, N-terminal pro-B-type natriuretic peptide, and the interleukin family member (ST2) were also measured. Left ventricular ejection fraction decreased (64 ± 5% to 59 ± 6%; P<0.0001) over 15 months. Twenty-six patients (32%, [22%-43%]) developed cardiotoxicity as defined by the Cardiac Review and Evaluation Committee Reviewing Trastuzumab; of these patients, 5 (6%, [2%-14%]) had symptoms of heart failure. Peak systolic longitudinal myocardial strain and ultrasensitive troponin I measured at the completion of anthracyclines treatment predicted the subsequent development of cardiotoxicity; no significant associations were observed for left ventricular ejection fraction, N-terminal pro-B-type natriuretic peptide, and ST2. Longitudinal strain was <19% in all patients who later developed heart failure. Conclusions-In patients with breast cancer treated with anthracyclines, taxanes, and trastuzumab, systolic longitudinal myocardial strain and ultrasensitive troponin I measured at the completion of anthracyclines therapy are useful in the prediction of subsequent cardiotoxicity and may help guide treatment to avoid cardiac side-effects.

The field of cardio-oncology is challenged to address an ever greater spectrum of cardiotoxicity associated with combination chemotherapy, greater dose intensity, extremes of age, and enhanced patient survival which exposes more protracted risk of developing congestive heart failure (CHF). Recent reports of chemotherapy-induced hypertension as a common adverse effect of angiogenesis inhibitors and immunosuppressants clarify the need for routine blood pressure (BP) monitoring and guideline-based management of hypertension as an integral strategy to preserve LV function. Serial monitoring of radionuclide left ventricular ejection fraction (LVEF) in adults and echocardiography in children continues to provide outcome based, cost-effective prevention of CHF in high risk patients receiving chemotherapy. To optimize treatment and monitoring strategies to eliminate late-onset LV dysfunction and CHF, traditional and novel candidate methods for assessment of chemotherapy-induced LV dysfunction are reviewed. These include serial assessment of LV volume indices by gated SPECT ERNA and gated SPECT MPI, 3D echocardiography and contrast 2D echocardiography; longitudinal strain imaging, diastolic functional parameters, 123 I-MIBG, 111 In-Antimyosin antibody imaging, and 99m Tc-Annexin V apoptosis imaging, biomarkers including troponins and BNP; genetic markers, and both functional and tissue characterization techniques with T1 weighted and T2 weighted images with cardiac magnetic resonance imaging (CMR). In our quest to optimize strategies for long-term cancer survival and prevention of CHF for patients receiving chemotherapy, rigorous modality and guideline-specific clinical outcome trials are required. A new multi-modality monitoring approach is proposed, which integrates evidencebased strengths of CMR, echocardiography, ERNA, biomarkers, and BP management for surveillance and validation of cardiotoxicity and prevention of clinical heart failure in patients receiving a broad spectrum of cancer therapies.
Timing of the negative effects of trastuzumab on cardiac mechanics after anthracycline chemotherapy
The international journal of cardiovascular imaging, 2016
Trastuzumab (TZB) has been shown to be extremely effective in breast cancer patients over-expressing HER-2, but careful cardiac monitoring is required when TZB is administered with anthracyclines, since the combination can increase its toxicity. Myocardial deformation indexes associated with speckle tracking echocardiography (STE) have proven to be very sensitive in identifying early myocardial dysfunction. An observational, prospective study was designed to assess TZB-induced cardiac damage using STE in patients with HER-2 positive breast cancer who had been sequentially treated with TZB following epirubicin (EPI). Conventional echocardiographic parameters and STE deformation indexes (longitudinal, radial, and circumferential strain/strain rate and apical rotation) were analyzed at baseline, after each EPI treatment, and 1 week after every other dose of TZB administration until 1 year follow up, in order to focus on the timing and extent of myocardial impairment. In the forty-five ...

Cardiologists and oncologists today face the daunting challenge of identifying patients at risk for late-onset left ventricular (LV) systolic dysfunction from the use of various chemotherapeutic agents. Currently, the most widely used method in clinical practice for monitoring the potential of chemotherapy-induced cardiotoxicity is calculation of LV ejection fraction. The use of LV ejection fraction to determine whether to continue or discontinue the use of chemotherapeutic agents is limited, because decreases in LV ejection fraction frequently occur late and can be irreversible. These limitations have led to the exploration of diastolic function and newer modalities that assess myocardial mechanics to identify sensitive and specific variables that can predict the occurrence of late systolic function. The cancer therapies associated with cardiotoxicity are reviewed in this report. Additionally, the authors evaluate the role of present-day echocardiographic parameters, complementary noninvasive imaging modalities, and biomarkers in the prediction of cardiotoxicity. The authors address the evolving role of cardioprotective agents and potential therapies to prevent or reverse the progression of LV systolic dysfunction. Finally, they provide some ideas regarding future directions to enhance the knowledge of predicting late-onset LV systolic dysfunction secondary to cancer therapy.
