Abstract

RESUMEN El reconocimiento inicial de la disfunción cardíaca ocasionada por estrategias terapéuticas aplicadas contra el cáncer fue realizado en la sexta década del siglo xx. La Cardiooncología es una nueva disciplina horizontal dirigida a la identificación de los pacientes en riesgo elevado para el desarrollo de toxicidad cardíaca. El eficaz desempeño inherente a la Cardiooncología pediátrica radica en la adecuada selección del medio diagnóstico capaz de identificar y evaluar los indicios de cardiotoxicidad mediante la detección de cambios precoces en la funcionalidad del miocardio tras la aplicación de terapias antitumorales y, sobre todo, la predicción a largo plazo de estos eventos en niños sobrevivientes de cáncer. La cardiotoxicidad secundaria a la terapéutica aplicada sobre estos pacientes es un problema de salud latente en nuestro país que precisa la adopción de medidas organizativas concebidas para su enfrentamiento. Se persigue contribuir a la estructuración de la atención integral correspondiente al niño con cáncer y afectado por cardiotoxicidad en Cuba.

ABSTRACT The initial recognition of cardiac dysfunction caused by therapeutic strategies applied against cancer was performed in the sixth decade of the twentieth century. Cardio-Oncology is a new horizontal discipline aimed at the identification of patients at high risk for the development of cardiac toxicity. The effective performance inherent in Pediatric cardio-oncology lies in the appropriate selection of the diagnostic mean which can be capable of identifying and evaluating the indications of heart toxicity by detecting early changes in myocardial functionality after the application of anti-tumour therapies and, above all, the long-term prediction of these events in children survivors of cancer. Cardiac toxicity secondary to the therapies applied on these patients is a latent health problem in our country that requires the adoption of organisational measures conceived for their confrontation. It is pursued to contribute to the structuring of the comprehensive care corresponding to children with cancer and affected by cardiotoxicity in Cuba.

Evaluation and management of patients with heart disease and cancer: cardio-oncology.

Joerg Herrmann, Amir Lerman, Nicole Sandhu … (2014)

The care for patients with cancer has advanced greatly over the past decades. A combination of earlier cancer diagnosis and greater use of traditional and new systemic treatments has decreased cancer-related mortality. Effective cancer therapies, however, can result in short- and long-term comorbidities that can decrease the net clinical gain by affecting quality of life and survival. In particular, cardiovascular complications of cancer treatments can have a profound effect on the health of patients with cancer and are more common among those with recognized or unrecognized underlying cardiovascular diseases. A new discipline termed cardio-oncology has thus evolved to address the cardiovascular needs of patients with cancer and optimize their care in a multidisciplinary approach. This review provides a brief introduction and background on this emerging field and then focuses on its practical aspects including cardiovascular risk assessment and prevention before cancer treatment, cardiovascular surveillance and therapy during cancer treatment, and cardiovascular monitoring and management after cancer therapy. The content of this review is based on a literature search of PubMed between January 1, 1960, and February 1, 2014, using the search terms cancer, cardiomyopathy, cardiotoxicity, cardio-oncology, chemotherapy, heart failure, and radiation.

Cardiovascular Health of Patients With Cancer and Cancer Survivors: A Roadmap to the Next Level.

Ana Barac, Gillian Murtagh, Joseph Carver … (2015)

Many existing and emerging cancer therapies have a significant effect on the cardiovascular health of patients with cancer and cancer survivors. This paper examines current aspects of interdisciplinary cardio-oncology clinical care delivery and education in the United States and outlines how these data provide a platform for future development of the field. We present the results of the nationwide survey on cardio-oncology services, practices, and opinions, conducted among chiefs of cardiology and program directors, which demonstrate ranges of clinical activities and identify significant interest for increased educational opportunities and expert training of cardiovascular physicians in this field. The survey respondents recognized clinical relevance but emphasized lack of national guidelines, lack of funds, and limited awareness and infrastructure as the main challenges for development and growth of cardio-oncology. We discuss potential solutions to unmet needs through interdisciplinary collaboration and the active roles of professional societies and other stakeholders.

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

Marc André Côté, Daniel Rayson, Nola Wurtele … (2016)

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. It includes recommendations and important management considerations with a focus on 4 main areas: identification of the high-risk population for cardiotoxicity, detection and prevention of cardiotoxicity, treatment of cardiotoxicity, and a multidisciplinary approach to cardio-oncology. All recommendations align with the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. Key recommendations for which the panel provides a strong level of evidence include: (1) that routine evaluation of traditional cardiovascular risk factors and optimal treatment of preexisting cardiovascular disease be performed in all patients before, during, and after receiving cancer therapy; (2) that initiation, maintenance, and/or augmentation of antihypertensive therapy be instituted per the Canadian Hypertension Educational Program guidelines for patients with preexisting hypertension or for those who experience hypertension related to cancer therapy; and (3) that investigation and management follow current Canadian Cardiovascular Society heart failure guidelines for cancer patients who develop clinical heart failure or an asymptomatic decline in left ventricular ejection fraction during or after cancer treatment. This guideline provides guidance to clinicians on contemporary best practices for the cardiovascular care of cancer patients.
