Cardiomyopathy Prevention in Cancer Patients

Left ventricular systolic dysfunction (LVSD) and overt heart failure are well known manifestations of chemotherapy-induced cardiotoxicity. The development of LVSD is clinically significant because it can impact the delivery of lifesaving chemotherapy and increase the risk of developing heart failure, compromising quality of life and survival years after cure of the cancer. Cancer treatment –related cardiomyopathy is most commonly associated with anthracyclines and trastuzumab. Several interventions have been identified to prevent cancer-induced cardiomyopathy. Anthracyclines is a major culprit, and prevention strategies with limiting cumulative dose, continuous infusion, dexrazoxane , and liposomal formulation have been shown to decrease the risk of cardiotoxicity.

AbstractLeft ventricular assist device (LVAD) is an established therapy for patients with severe heart failure. Because the incidence of cardiotoxicity owing to anticancer agents is low, it is difficult to predict the recovery prospects when the cause of heart failure is due to anticancer agents. In this context, cancer patients who present with severe symptoms of heart failure and who fail medical therapy for heart failure may pose a dilemma, especially in countries such as Japan where implantable LVADs are not approved for purposes other than bridging to transplant. Recently, we encountered a 32-year-old woman with chemo...

German cancer registry (Robert-Koch-Institute) data has shown a 16 fold risk of cancer in those with peripartum cardiomyopathy [1]. According to the report 21 of 236 patients had cancer, of which 12 had cancer diagnosed before peripartum cardiomyopathy. 11 of them had cardiotoxic chemotherapy. Of these, 17% fully recovered cardiac function compared to 55% of peripartum cardiomyopathy patients without cancer. Of the 10 patients who developed cancer after peripartum cardiomyopathy, 80% had left ventricular ejection fraction of 50% or more after cancer therapy. Authors mention that the high prevalence could be due to geneti...

Publication date: Available online 26 November 2019Source: Redox BiologyAuthor(s): Balaraman KalyanaramanAbstractDoxorubicin (DOX), or Adriamycin, an anthracycline antibiotic discovered serendipitously as a chemotherapeutic drug several decades ago, is still one of the most effective drugs for treating various adult and pediatric cancers (breast cancer, Hodgkin's disease, lymphoblastic leukemia). However, one of the major side effects of the continuous use of DOX is dose-dependent, long-term, and potentially lethal cardiovascular toxicity (congestive heart failure and cardiomyopathy) in cancer survivors many years after ce...

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

In this study, we used large-scale electronic health records data from multiple linked UK databases to address these evidence gaps.MethodsFor this population-based cohort study, we used linked primary care, hospital, and cancer registry data from the UK Clinical Practice Research Datalink to identify cohorts of survivors of the 20 most common cancers who were 18 years or older and alive 12 months after diagnosis and controls without history of cancer, matched for age, sex, and general practice. We compared risks for a range of cardiovascular disease outcomes using crude and adjusted Cox models. We fitted interactions to in...

Anthracycline (doxorubicin) and trastuzumab treatments for cancer patients have been known to cause cardiotoxicity. The current recommendations for prevention of cardiac events from cancer chemotherapies are largely based on opinion. The American Society of Clinical Oncology recommends active screening and prevention of modifiable cardiovascular risk factors. The risk factors are defined as tobacco use, high blood pressure, high cholesterol, alcohol use, obesity, and physical inactivity. Beta-adrenergic blockers and angiotensin converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARBs) have been the mainstay o...

AbstractCardiogenic shock (CS) is increasingly recognized in patients with malignancies, while cancer is independently associated with worse prognosis in CS. A number of conditions may lead to CS in cancer, including acute coronary syndromes, cardiomyopathy, takotsubo syndrome, myocarditis, pulmonary embolism, tamponade, and cardiac herniation. In these conditions, CS may be related to cancer itself or to cancer therapy, including surgery, chemotherapy, or radiotherapy. Given the significantly improved overall survival of patients with malignancies, the early recognition and proper management of CS in cancer become increas...

Purpose of review The number of cancer survivors is increasing, and cardiovascular events are a significant cause of morbidity and mortality in these patients. Preexisting cardiovascular conditions as well as the development of cancer therapeutics-related cardiac dysfunction (CTRCD), in particular left ventricular dysfunction and heart failure, limit the options for cancer therapies for these patients and contribute to reduced cancer survival. Recent findings Recent guidelines and position statements from various cardiology and oncology societies provide an outline for the practicing physician for the management of CT...
