Associations between Growth Differentiation Factor 15, Cardiac Troponin T, and N-terminal pro-B-type Natriuretic Peptide, and Future Myocardial Fibrosis Assessed by Cardiac Magnetic Resonance Imaging: Data from the Akershus Cardiac Examination 1950 Study.

Background: Myocardial fibrosis is associated with a poor outcome for patients with cardiovascular disease (CVD). Growth differentiation factor 15 (GDF-15) concentrations predict the risk of death in patients with CVD, but the underlying pathophysiological mechanisms are poorly understood. We aimed to assess the associations between biomarkers of cellular stress and inflammation (GDF-15), cardiac injury (cardiac troponin T [cTnT]), and stretch (N-terminal pro-B-type natriuretic peptide [NT-proBNP]), and subsequent focal and diffuse myocardial fibrosis assessed by cardiac magnetic resonance (CMR) imaging.

Cardiac troponin T associates with left ventricular function and synchrony assessed by CMR in the general population: results from the Akershus Cardiac Examination 1950 Study.

Background And Aim: Cardiac troponin T (cTnT) is a blood biomarker of myocardial injury that is associated with future adverse cardiovascular events in the general population. Left ventricular (LV) global longitudinal strain (GLS) and mechanical dispersion (MD) are metrics of systolic function and synchrony that can be obtained from cardiac imaging. Studies suggest an association between cTnT and echocardiographically assessed GLS and MD, but it is unknown whether cTnT relates to these metrics when assessed by cardiac magnetic resonance (CMR).

Trajectory of cardiac troponin T following moderate-to-severe COVID-19 and the association with cardiac abnormalities.

Background: COVID-19 has been associated with cardiac troponin T (cTnT) elevations and changes in cardiac structure and function, but the link between cardiac dysfunction and high-sensitive cardiac troponin T (hs-cTnT) in the acute and convalescent phase is unclear.

Objective: To assess whether hs-cTnT concentrations are associated with cardiac dysfunction and structural abnormalities after hospitalization for COVID-19, and to evaluate the performance of hs-cTnT to rule out cardiac pathology.

Methods: Patients hospitalized with COVID-19 had hs-cTnT measured during the index hospitalization and after 3-and 12 months, when they also underwent an echocardiographic study.

Impact of the ESC Cardio-Oncology Guidelines Biomarker Criteria on Incidence of Cancer Therapy-Related Cardiac Dysfunction.

Background: The impact of recent consensus definitions of cancer therapy-related cardiac dysfunction (CTRCD) from the European Society of Cardiology cardio-oncology guidelines on the reported incidence of CTRCD has not yet been assessed.

Objectives: The aim of this study was to assess the: 1) cumulative incidence; 2) point prevalence during and after adjuvant therapy; and 3) prognostic value of CTRCD as defined by different asymptomatic CTRCD guideline criteria.

Methods: The cumulative incidence and point prevalence of CTRCD were retrospectively assessed in 118 patients participating in the PRADA (Prevention of Cardiac Dysfunction During Adjuvant Breast Cancer Therapy) trial.

Minor Myocardial Scars in Association with Cardiopulmonary Function after COVID-19.

Background: Myocardial scars detected by cardiovascular magnetic resonance (CMR) imaging after COVID-19 have caused concerns regarding potential long-term cardiovascular consequences.

Objective: The objective of this study was to investigate cardiopulmonary functioning in patients with versus without COVID-19-related myocardial scars.

Methods: In this prospective cohort study, CMR was performed approximately 6 months after moderate-to-severe COVID-19.

The Role of Cardioprotection in Cancer Therapy Cardiotoxicity: State-of-the-Art Review.

Cardiotoxicity is a relatively frequent and potentially serious side effect of traditional and targeted cancer therapies. Both general measures and specific pharmacologic cardioprotective interventions as well as imaging- and biomarker-based surveillance strategies to identify patients at high risk have been tested in randomized controlled trials to prevent or attenuate cancer therapy-related cardiotoxic effects. Although meta-analyses including early trials suggest an overall beneficial effect, there is substantial heterogeneity in results.

Cardiac pathology 6 months after hospitalization for COVID-19 and association with the acute disease severity.

Background: Coronavirus disease 2019 (COVID-19) may cause myocardial injury and myocarditis, and reports of persistent cardiac pathology after COVID-19 have raised concerns of long-term cardiac consequences. We aimed to assess the presence of abnormal cardiovascular resonance imaging (CMR) findings in patients recovered from moderate-to-severe COVID-19, and its association with markers of disease severity in the acute phase.

Methods: Fifty-eight (49%) survivors from the prospective COVID MECH study, underwent CMR median 175 [IQR 105-217] days after COVID-19 hospitalization.

Prevention of Cardiac Dysfunction During Adjuvant Breast Cancer Therapy (PRADA): Extended Follow-Up of a 2×2 Factorial, Randomized, Placebo-Controlled, Double-Blind Clinical Trial of Candesartan and Metoprolol.

Background: Adjuvant breast cancer therapy containing anthracyclines with or without anti-human epidermal growth factor receptor-2 antibodies and radiotherapy is associated with cancer treatment-related cardiac dysfunction. In the PRADA trial (Prevention of Cardiac Dysfunction During Adjuvant Breast Cancer Therapy), concomitant treatment with the angiotensin receptor blocker candesartan attenuated the reduction in left ventricular ejection fraction (LVEF) in women receiving treatment for breast cancer, whereas the β-blocker metoprolol attenuated the increase in cardiac troponins. This study aimed to assess the long-term effects of candesartan and metoprolol or their combination to prevent a reduction in cardiac function and myocardial injury.

Neurohormonal Blockade and Circulating Cardiovascular Biomarkers During Anthracycline Therapy in Breast Cancer Patients: Results From the PRADA (Prevention of Cardiac Dysfunction During Adjuvant Breast Cancer Therapy) Study.

Background: Anthracyclines are associated with cardiotoxic effects. Cardiovascular biomarkers may reflect myocardial injury, dysfunction, inflammation, and fibrosis and may precede and predict the development of left ventricular impairment. The aim of this study was to assess: (1) longitudinal change in circulating cardiovascular biomarkers, (2) the effect of metoprolol succinate and candesartan cilexetil on the biomarker response, and (3) the associations between on-treatment changes in biomarker concentrations and subsequent left ventricular dysfunction in patients with early breast cancer receiving anthracyclines.

Effect of candesartan and metoprolol on myocardial tissue composition during anthracycline treatment: the PRADA trial.

Aims: Anthracycline treatment may cause myocyte loss and expansion of the myocardial extracellular volume (ECV) fraction by oedema and fibrosis. We tested the hypotheses that adjuvant treatment for early breast cancer with the anthracycline epirubicin is dose dependently associated with increased ECV fraction and total ECV, as well as reduced total myocardial cellular volume, and that these changes could be prevented by concomitant angiotensin or beta-adrenergic blockade.

Methods And Results: PRevention of cArdiac Dysfunction during Adjuvant breast cancer therapy (PRADA) was a 2 × 2 factorial, placebo-controlled, double-blinded trial of candesartan and metoprolol.

Prevention of cardiac dysfunction during adjuvant breast cancer therapy (PRADA): a 2 × 2 factorial, randomized, placebo-controlled, double-blind clinical trial of candesartan and metoprolol.

Aims: Contemporary adjuvant treatment for early breast cancer is associated with improved survival but at the cost of increased risk of cardiotoxicity and cardiac dysfunction. We tested the hypothesis that concomitant therapy with the angiotensin receptor blocker candesartan or the β-blocker metoprolol will alleviate the decline in left ventricular ejection fraction (LVEF) associated with adjuvant, anthracycline-containing regimens with or without trastuzumab and radiation.

Methods And Results: In a 2 × 2 factorial, randomized, placebo-controlled, double-blind trial, we assigned 130 adult women with early breast cancer and no serious co-morbidity to the angiotensin receptor blocker candesartan cilexetil, the β-blocker metoprolol succinate, or matching placebos in parallel with adjuvant anticancer therapy.

[Cardioprotective treatment during adjuvant cancer therapy].

Background: Cardiac dysfunction in the form of reduced systolic and/or diastolic left ventricular function after adjuvant cancer therapy has recently attracted increasing attention. The best-known cardiotoxic agents are anthracyclines and the recombinant antibody trastuzumab. Patients treated with radiotherapy to the thorax are liable to develop coronary artery disease.

Rationale and design of the prevention of cardiac dysfunction during an Adjuvant Breast Cancer Therapy (PRADA) Trial.

Objective: The PRevention of cArdiac Dysfunction during Adjuvant breast cancer therapy (PRADA) study is a randomized, placebo-controlled, double-blind trial to determine whether angiotensin receptor blockers (ARB), or beta-blockers or their combination may prevent the development of left ventricular (LV) dysfunction in patients on standard adjuvant treatment for early breast cancer.

Methods: Following surgical resection, 120 breast cancer patients scheduled for adjuvant epirubicin-containing chemotherapy and, if indicated, trastuzumab, will be included. They will be randomized to an ARB (candesartan), a beta-blocker (metoprolol) and matching placebos in a 2 × 2 factorial design.
