Cardio-Oncology: A Continually Evolving Subspecialty in Oncology Nursing

The role of a cardio-oncology clinical nurse specialist in the United Kingdom

Cardio-oncology is a growing subspeciality of cardiology that involves the prevention and early detection of cancer therapy-related cardiovascular toxicity (CTR-CVT). Cardiovascular complications can occur before, during and after cancer treatment, due to de novo cardiotoxicity or an exacerbation of a previous cardiac condition. Therefore, cancer patients undergoing cancer treatment need to be assessed before, during and after their cancer treatment. This article describes the development and progress of a specialised nursing role, known as a Clinical Nurse Specialist (CNS), at the Royal Brompton Hospital in London, United Kingdom (UK).

Cardiotoxicity in people undergoing cancer treatment - the role of the oncology nurse

Cardiotoxicity is a significant complication of cancer treatment, and this review describes the cardiovascular risks associated with various therapies and emphasizes the crucial role of oncology nurses in managing these risks. Many cancer treatments, including cytotoxic therapies, radiation, targeted therapies, and immune-modulatory drugs, have been shown to increase the likelihood of cardiovascular toxicity, leading to conditions such as acute coronary syndrome, heart failure, and atrial fibrillation. Guidelines are now available to reduce treatment-related cardiovascular toxicity (CTR-CVT) and stress the importance of cardiovascular assessments before, during, and after cancer treatment. Oncology nurses are pivotal in performing these assessments and collaborating within multidisciplinary teams, including cardiologists, to ensure optimal care. As more patients successfully complete cancer treatment, it becomes essential to integrate cardiovascular risk evaluation, education, and medication into routine oncology care. The evolving field of oncology nursing, particularly with the rise of emerging therapies and aging populations, requires further education on early detection and management of cardiotoxicity to enhance patient outcomes.

The Role of Nursing in the Delivery of Cardio-Oncology

OPINION STATEMENT

Nurses are the "heart of patient care" and in the forefront of the health care delivery for cardio-oncology patients. Nurses play a critical central role in maximizing longitudinal health of cancer patients and survivors through the prevention of cardiovascular complications throughout the patient's cancer care journey. Nurses function in a variety of roles such as nurse clinicians, advanced practice nurses (APNs)or nurse practitioners (NPs), patient educators, managers, nurse navigators or nurse researchers. The role of nurses, particularly the advanced practice nurses as key members in delivering cardio-oncology care is evolving. However, despite the rapidly increasing growth of cardio oncology programs globally, a pivotal need remains to develop and provide formalized training programs for nurses, NPs and APNs. At present, no formal academic cardio-oncology nurse training program or certification exists. There is clearly more work to be done on the role of nurses in cardio-oncology care. As cardio-oncology evolves to become a key specialty with dedicated services being established across the globe, the role of the nurse in delivering this service is critical and a concerted collaborative approach between the two distinct specialties of cardiology and oncology needs to ensure the nursing workforce is educationally prepared and confident to treat and manage cardio-oncology patients.

Associations of Health-Related Quality of Life and Sleep Disturbance With Cardiovascular Disease Risk in Postmenopausal Breast Cancer Survivors

BACKGROUND

Breast cancer (BC) survivors are at an increased risk of long-term cardiovascular disease (CVD), often attributed to cancer treatment. However, cancer treatment may also negatively impact health-related quality of life (HRQoL), a risk factor of CVD in the general population.

OBJECTIVE

We examined whether sleep disturbance, and physical or mental HRQoL were associated with CVD risk in BC survivors.

METHODS

We conducted a longitudinal analysis in the Women's Health Initiative of postmenopausal women given a diagnosis of invasive BC during follow-up through 2010 with no history of CVD before BC. The primary outcome was incident CVD, defined as physician-adjudicated coronary heart disease or stroke, after BC. Physical and mental HRQoL, measured by the Short-Form 36 Physical and Mental Component Summary scores, and sleep disturbance, measured by the Women's Health Initiative Insomnia Rating Scale, were recorded post BC. Time-dependent Cox proportional hazards models were used starting at BC diagnosis until 2010 or censoring and adjusted for relevant confounders.

RESULTS

In 2884 BC survivors, 157 developed CVD during a median follow-up of 9.5 years. After adjustment, higher Physical Component Summary scores were significantly associated with a lower risk of CVD (hazard ratio, 0.90 [95% confidence interval, 0.81-0.99]; per 5-point increment in Physical Component Summary). No associations with CVD were found for Mental Component Summary or Insomnia Rating Scale.

CONCLUSION

In BC survivors, poor physical HRQoL is a significant predictor of CVD.

IMPLICATIONS FOR PRACTICE

Our findings highlight the importance for nurses to assess and promote physical HRQoL as part of a holistic approach to mitigating the risk of CVD in BC survivors.

Cardio-Oncology Health Disparities: Social Determinants of Health and Care for Black Breast Cancer Survivors

BACKGROUND

Black women experience higher rates of cardiotoxicity and cardiovascular disease (CVD)-related comorbidities than White women. These racial and ethnic disparities are primarily from the earlier onset of CVD risk factors, social determinants of health (SDOH), and cardiotoxicity screening and surveillance disparities.

OBJECTIVES

This article discusses the role of SDOH in cardio-oncology and strategies to prevent and detect adverse cardiovascular outcomes among Black breast cancer survivors.

METHODS

Preliminary case study findings are presented, including treatment exposures to cardiotoxicity and SDOH in cardio-oncology influencing health outcomes in Black breast cancer survivors.

FINDINGS

Nurses can address SDOH and racial disparities in cardio-oncology by being mindful of Black breast cancer survivors' increased burden of CVD risk factors, evaluating barriers to receive preventive care and cardio-oncology rehabilitation, practicing cultural humility, and adhering to evidence-based guidelines for behavioral risk management for Black breast cancer survivors.
