anthracycline cardio

Munthir Mansour, Todd W Gress, Maria R B Tria Tirona
: 213 Background: Anthracyclines and anti-Her-2 targeted therapy are commonly used effective breast cancer treatments. They are known to decrease Left Ventricular Ejection Fraction (LVEF), which may increase patients' morbidity and mortality. There is currently no consensus on post treatment cardiac follow-up. Recent observations suggested that ACEI and B blocker drugs could have cardioprotective effects. We conducted a retrospective study to assess patients' cardiac outcome using post-treatment LVEF follow-up and effect of ACEI and B blocker on cardiac outcome for breast cancer patients who received cardiotoxic agents in our institution...

BACKGROUND: Anthracyclines (AC), widely used and effective anticancer agents, are known to induce both acute and chronic declines in cardiovascular health, ranging in severity from asymptomatic, subclinical dysfunction to substantial cardiomyopathy leading to congestive heart failure and death. There is substantial evidence that physical activity, higher levels of cardiorespiratory fitness, and exercise therapy can help prevent cardiovascular disease. Moreover, animal studies have shown that exercise performed concomitantly with AC treatment may attenuate early cardiac damage that results from AC exposure...

The numbers of survivors of cancer have increased as a consequence of advances in chemotherapy; however, the side effects of cancer treatment have become increasingly more important. The most frequent side effects include cardiovascular complications, which can lead to acute and delayed morbidity and mortality, often many years later. The discipline of cardio-oncology deals with the prevention, diagnostics and treatment of cardiovascular diseases caused by cancer therapy. The most important cardiovascular side effects of cytostatic therapy are heart failure due to myocardial dysfunction (cardiotoxicity), coronary artery disease, valvular disease and ventricular arrhythmia as a result of QT extension...

Advances in oncologic therapies have allowed many patients with breast cancer to achieve better outcomes and longer survival. However, this progress has been tempered by cardiotoxicity, associated with anticancer therapies, ranging from subclinical abnormalities to irreversible life-threatening complications, such as congestive heart failure or cardiomyopathy. In particular, exposure to chemotherapy (CHT), including anthracyclines and trastuzumab, can lead to cardiac dysfunction with short- or long-term consequences, among patients with breast cancer...

Mitoxantrone (1,4-dihydroxy-5,8-bis[[2-[(2-hydroxyethyl)amino]ethyl]amino]-9,10-anthracenedione) is a synthetically designed antineoplastic agent and structurally similar to classical anthracyclines. It is widely used as a potent chemotherapeutic component against various kinds of cancer and possesses lesser cardio-toxic effects with respect to naturally occurring anthracyclines. In the present study, we have investigated the binding features of mitoxantrone-tRNA complexation at physiological pH using attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, circular dichroism (CD) spectroscopy, isothermal titration calorimetry, and UV-visible absorption spectroscopic techniques...

BACKGROUND: Cardio-oncology is a collaborative approach between cardiologists and oncologists in the treatment of patients with cancer and heart disease. Radiation and chemotherapy have played a major role in the decreased cancer-related mortality achieved in the past 2 decades. However, anthracycline-, tyrosine kinase-, and radiation-based therapies are each associated with independent cardiovascular (CV) risks, and these risks are cumulative when these therapies are used in combination...

BACKGROUND: Cancer is the leading cause of premature death in Canada. In the last decade, important gains in cancer survival have been achieved by advances in adjuvant treatment. However, many oncologic treatments also result in cardiovascular "toxicity". Furthermore, cardiac risk factors such as hypertension, dyslipidemia, and diabetes mellitus are known to contribute to the progression of cardiac damage and clinical cardiotoxicity. As such, for many survivors, the risk of death from cardiac disease exceeds that of recurrent cancer...

Patients with cancer can present with difficult management issues, as the medicine can sometimes cause sequelae destructive to healthy tissue. As this population lives longer, cardiotoxic effects are beginning to emerge, but the early recognition of this signal can prove difficult, with too late a recognition leading to lifelong cardiac impairment and dysfunction. Cardio-oncology can bridge this difficulty, and echocardiography and its newer imaging abilities are proving efficacious in this population. This article will address common sequelae of cardiotoxic treatment regimens and offer recommendations for echocardiographic surveillance...

Considerable advances in cancer therapies in recent decades have reshaped the prognosis of cancer patients. There are now estimated to be over 20 million cancer survivors in the USA and Europe, numbers unimaginable a few years ago. However, this increase in survival, along with the aging of the patient population, has been accompanied by a rise in adverse cardiovascular effects, particularly when there is a previous history of heart disease. The incidence of cardiotoxicity continues to grow, which can compromise the effectiveness of cancer therapy...

Background Anthracycline drugs are effective anticancer agents, but their optimal use is limited in many patients by the associated cardiotoxicity, even at designated safe doses. As conventionally sensitive cardiac troponin-I assays fail to reliably quantify concentrations of cardiac troponin-I below 30 ng/L, we investigated the potential role of high-sensitive cardiac troponin-I in the detection of subclinical cardiomyocyte injury in patients treated with anthracycline agents. Methods Serial high-sensitive cardiac troponin-I concentrations were assessed in 84 patients, receiving anthracycline-containing ( n = 38) and non-anthracycline-containing ( n = 46) regimens...

Anthracyclines, such as doxorubicin, are the most potent and widely used chemotherapeutic agents for the treatment of a variety of human cancers, including solid tumors and hematological malignancies. However, their clinical use is hampered by severe cardiotoxic side effects and cancer therapy-related heart disease has become a leading cause of morbidity and mortality among cancer survivors. The identification of therapeutic strategies limiting anthracycline cardiotoxicity with preserved antitumor efficacy thus represents the current challenge of cardio-oncologists...

Nijmegen breakage syndrome (NBS, MIM #251260) is an autosomal recessive chromosomal instability disorder. Majority of patients affected are of Slavic origin and share the same founder mutation of 657del5 within the NBN gene encoding protein involved in DNA double-strand breaks repair. Clinically, this is characterized by a microcephaly, immunodeficiency and a high incidence of pediatric malignancies, mostly lymphomas and leukemias. Anticancer treatment among patients with NBS is challenging because of a high risk of life threatening therapy-related toxicity including severe infections, bone marrow failure, cardio- and nephrotoxicity and occurrence of secondary cancer...

Cardiovascular disease (CVD) and breast cancer cause substantial morbidity and mortality in women and are major public health concerns in the USA. While aggressive screening and targeted, advanced treatment for breast cancer have had a measurable impact on breast cancer survival, treatment is not without significant cardiotoxic effects. Anthracycline-based chemotherapy can lead to left ventricular dysfunction and failure, as well as a decline in exercise tolerance and cardio-pulmonary reserve despite preserved ejection fraction...

Increased awareness of the cardiovascular toxic effects of chemotherapy has led to the emergence of cardio-oncology (or onco-cardiology), which focuses on screening, monitoring and treatment of patients with cardiovascular dysfunctions resulting from chemotherapy. Anthracyclines, such as doxorubicin, and HER2 inhibitors, such as trastuzumab, both have cardiotoxic effects. The biological rationale, mechanisms of action and cardiotoxicity profiles of these two classes of drugs, however, are completely different, suggesting that cardiotoxic effects can occur in a range of different ways...

Doxorubicin, an anthracycline antibiotic, has been used as an anti-neoplastic drug for almost 60 years. However, the mechanism(s) by which anthracyclines cause irreversible myocardial injury remains unclear. In order to delineate possible molecular signals involved in the myocardial toxicity, we assessed candidate genes using mRNA expression profiling in the doxorubicin-treated rat cardiomyocyte H9c2 cell line. In the study, it was confirmed that myogenin, an important transcriptional factor for muscle terminal differentiation, was significantly reduced by doxorubicin in a dose-dependent manner using both RT-PCR and western blot analyses...

OBJECTIVE: Anthracyclines are potent antineoplastic agents in the treatment of lymphoid malignancies, but their therapeutic benefit is limited by cardiotoxicity. The American Heart Association (AHA) recommends routine surveillance, early diagnosis and treatment of anthracycline-based chemotherapy (AC) induced cardiomyopathy (AC-CMP). We aimed to assess the prevalence of AC-CMP in patients with lymphoma, surveillance patterns of left ventricular ejection fraction (LVEF) in those receiving AC and management of patients with AC-CMP at an academic medical centre prior to the development of a comprehensive cardio-oncology programme...

Cardiomyopathy is an adverse outcome of antineoplastic drug therapy that has become increasingly relevant in the management of cancer survivors. As the efficacy of anticancer treatments has improved, long-term outcomes are altered by the development of cardiotoxicity, which may be associated with an even worse prognosis than that of the underlying malignancy. From the research into mechanisms, prevention, and treatment, the specialized field of cardio-oncology has evolved, but the recognition and appropriate management of these patients is important for the general internist and general cardiologist as well...

Advances in chemotherapeutic agents over the past two decades have resulted in significantly improved cancer survival rates. Cardiac toxicity, however, has emerged as a leading cause of morbidity, both during and years after treatment. One of the most common manifestations of cardiotoxicity is that of heart failure and left ventricular systolic dysfunction. Consequently, the field of cardio-oncology is a rapidly emerging field of sub-specialty, with growing research interests in all aspects of management. In this review, current opinions and guidelines in this field are discussed, with particular focus on the most common culprits, the anthracyclines and the monoclonal antibody, trastuzumab...
