Socioeconomic variations determine the clinical presentation, aetiology, and outcome of infective endocarditis: a prospective cohort study from the ESC-EORP EURO-ENDO (European Infective Endocarditis) registry.

Aims: Infective endocarditis (IE) is a life-threatening disease associated with high mortality and morbidity worldwide. We sought to determine how socioeconomic factors might influence its epidemiology, clinical presentation, investigation and management, and outcome, in a large international multicentre registry.

Methods And Results: The EurObservational Programme (EORP) of the European Society of Cardiology EURO-ENDO (European Infective Endocarditis) registry comprises a prospective cohort of 3113 adult patients admitted for IE in 156 hospitals in 40 countries between January 2016 and March 2018.

Changes in Citric Acid Cycle and Nucleoside Metabolism Are Associated with Anthracycline Cardiotoxicity in Patients with Breast Cancer.

Anthracyclines and HER2-targeted antibodies are very effective for the treatment of breast cancer, but their use is limited by cardiotoxicity. In this nested case-control study, we assessed the role of intermediary metabolism in 38 women with breast cancer treated with anthracyclines and trastuzumab. Using targeted mass spectrometry to measure 71 metabolites in the plasma, we identified changes in citric acid and aconitic acid that differentiated patients who developed cardiotoxicity from those who did not.

Absence of cardiotoxicity with prolonged treatment and large accumulating doses of pegylated liposomal doxorubicin.

Background: Pegylated liposomal doxorubicin (PLD) is used as a second-line therapy for gynecologic cancers, with a better short-term toxicity profile compared to doxorubicin or other anthracyclines.

Methods: We screened 14 patients with recurrent gynecologic cancers, who underwent prolonged treatment with large cumulative doses of PLD for overt or subtle signs of cardiotoxicity (CTX) using standard and advanced echocardiography techniques [3D volumetric method for left ventricular ejection fraction (LVEF) and left ventricular/right ventricular global longitudinal strain]. Half the patients had previous echocardiographic studies available for comparison.

Contraction Timing Patterns in Patients Treated for Breast Cancer Before and After Anthracyclines Therapy.

Background: During the development of heart failure (HF), the changes of contraction timing pattern and temporal heterogeneity of segmental contraction happen early and may precede both symptomatic HF and the decrease in left ventricular ejection fraction (LVEF). In patients treated with anthracyclines, both symptomatic HF and the decrease of LVEF are detected once significant myocardial injury has occurred. The aim of the current study was to investigate whether changes in the timing of contraction can be detected early after anthracyclines therapy.

Canadian Cardiovascular Society Guidelines for Evaluation and Management of Cardiovascular Complications of Cancer Therapy.

Modern treatment strategies have led to improvements in cancer survival, however, these gains might be offset by the potential negative effect of cancer therapy on cardiovascular health. Cardiotoxicity is now recognized as a leading cause of long-term morbidity and mortality among cancer survivors. This guideline, authored by a pan-Canadian expert group of health care providers and commissioned by the Canadian Cardiovascular Society, is intended to guide the care of cancer patients with established cardiovascular disease or those at risk of experiencing toxicities related to cancer treatment.

Sex-specific cardiovascular responses to control or high fat diet feeding in C57bl/6 mice chronically exposed to bisphenol A.

The increased pericardial fat which often accompanies overall obesity is thought to alter cardiac structure/function and increase the risk for atrial fibrillation. We hypothesized that chronic exposure to bisphenol A (BPA) would induce pericardial fat, cardiac hypertrophy or arrhythmia. C57bl/6n dams were exposed to BPA (25 ng/ml drinking water) beginning on gestation day 11 and progeny continued on 2.

Longitudinal Changes in Multiple Biomarkers Are Associated with Cardiotoxicity in Breast Cancer Patients Treated with Doxorubicin, Taxanes, and Trastuzumab.

Background: Biomarkers may play an important role in identifying patients at risk for cancer therapy cardiotoxicity. Our objectives were to define the patterns of change in biomarkers with cancer therapy and their associations with cardiotoxicity.

Methods: In a multicenter cohort of 78 breast cancer patients undergoing doxorubicin and trastuzumab therapy, 8 biomarkers were evaluated at baseline and every 3 months over a maximum follow-up of 15 months.

Time Trends of Left Ventricular Ejection Fraction and Myocardial Deformation Indices in a Cohort of Women with Breast Cancer Treated with Anthracyclines, Taxanes, and Trastuzumab.

Background: 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.

Transcatheter heart valve failure: a systematic review.

Aims: A comprehensive description of transcatheter heart valve (THV) failure has not been performed. We undertook a systematic review to investigate the aetiology, diagnosis, management, and outcomes of THV failure.

Methods And Results: The systematic review was performed in accordance with the PRISMA guidelines using EMBASE, MEDLINE, and Scopus.

Early increases in multiple biomarkers predict subsequent cardiotoxicity in patients with breast cancer treated with doxorubicin, taxanes, and trastuzumab.

Objectives: The aim of this study was to determine if individual or multiple biomarkers are associated with cardiotoxicity in patients with breast cancer undergoing cancer therapy.

Background: Current methods to identify patients at risk for cardiotoxicity from cancer therapy are inadequate.

Methods: We measured 8 biomarkers in a multicenter cohort of 78 patients with breast cancer undergoing doxorubicin and trastuzumab therapy: ultrasensitive troponin I (TnI), high-sensitivity C-reactive protein (CRP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), growth differentiation factor (GDF)-15, myeloperoxidase (MPO), placental growth factor (PlGF), soluble fms-like tyrosine kinase receptor (sFlt)-1, and galectin (gal)-3.

Expert consensus for multi-modality imaging evaluation of cardiovascular complications of radiotherapy in adults: a report from the European Association of Cardiovascular Imaging and the American Society of Echocardiography.

Cardiac toxicity is one of the most concerning side effects of anti-cancer therapy. The gain in life expectancy obtained with anti-cancer therapy can be compromised by increased morbidity and mortality associated with its cardiac complications. While radiosensitivity of the heart was initially recognized only in the early 1970s, the heart is regarded in the current era as one of the most critical dose-limiting organs in radiotherapy.

Cardiac structure/function, protein expression, and DNA methylation are changed in adult female mice exposed to diethylstilbestrol in utero.

The detrimental effects of in utero exposure to the non-steroidal estrogen diethylstilbestrol (DES) are particularly marked in women. Fetal hearts express estrogen receptors, making them potentially responsive to DES. To examine whether gestational exposure to DES would impact the heart, we exposed pregnant C57bl/6n dams to DES (0.

Human resistin in chemotherapy-induced heart failure in humanized male mice and in women treated for breast cancer.

Resistin is a circulating mediator of insulin resistance mainly expressed in human monocytes and responsive to inflammatory stimuli. Recent clinical studies have connected elevated resistin levels with the development and severity of heart failure. To further our understanding of the role of human resistin in heart failure, we studied a humanized mouse model lacking murine resistin but transgenic for the human Retn gene (Hum-Retn mice), which exhibits basal and inflammation-stimulated resistin levels similar to humans.

Cardiotoxicity of cancer therapeutics: current issues in screening, prevention, and therapy.

In the context of modern cancer chemotherapeutics, cancer survivors are living longer and being exposed to potential comorbidities related to non-cancer side effects of such treatments. With close monitoring of cancer patients receiving potentially cardiotoxic medical therapies, oncologists, and cardiologists alike are identifying patients in both clinical and subclinical phases of cardiovascular disease related to such chemotherapies. Specifically, cardiotoxicity at the level of the myocardium and potential for the development of heart failure are becoming a growing concern with increasing survival of cancer patients.

Lifelong exposure to bisphenol a alters cardiac structure/function, protein expression, and DNA methylation in adult mice.

Bisphenol A (BPA) is an estrogenizing endocrine disruptor compound of concern. Our objective was to test whether lifelong BPA would impact cardiac structure/function, calcium homeostasis protein expression, and the DNA methylation of cardiac genes. We delivered 0.

The impact of doxorubicin and dexrazoxane injection of prepubertal female rats on pregnancy outcome and cardiac function postpartum.

Childhood cancer survivors can develop significant cardiac dysfunction in adulthood as a consequence of their cancer treatment. Studies have linked heart failure during pregnancy to childhood doxorubicin (DOX) exposure. We hypothesized that DOX injection would reduce cardiac function peripartum and that DOX-treated dams would show greater cardiac remodeling postweaning.

Gestational exposure to diethylstilbestrol alters cardiac structure/function, protein expression and DNA methylation in adult male mice progeny.

Pregnant women, and thus their fetuses, are exposed to many endocrine disruptor compounds (EDCs). Fetal cardiomyocytes express sex hormone receptors making them potentially susceptible to re-programming by estrogenizing EDCs. Diethylstilbestrol (DES) is a proto-typical, non-steroidal estrogen.

Right ventricular end-diastolic wall stress: does it impact on right atrial size, and does it differ in right ventricular pressure vs volume loading conditions?

Background: Right ventricular (RV) diastolic dysfunction precedes RV systolic dysfunction. Improvement in noninvasive assessment of RV diastolic function may enable earlier detection of RV dysfunction, especially important in the assessment of patients with congenital heart disease. We investigated a new parameter we call RV end-diastolic wall stress (RVEDWS) in an effort to better characterize RV diastolic function.

Assessment of echocardiography and biomarkers for the extended prediction of cardiotoxicity in patients treated with anthracyclines, taxanes, and trastuzumab.

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.

Cardiac response to doxorubicin and dexrazoxane in intact and ovariectomized young female rats at rest and after swim training.

The impact of cancer therapies on adult cardiac function is becoming a concern as more children survive their initial cancer. Cardiovascular disease is now a significant problem to adult survivors of childhood cancer. Specifically, doxorubicin (DOX) may be particularly harmful in young girls.
