Cardiotoxicity in Hematopoietic Stem Cell Transplant: Keeping the Beat.

INTRODUCTION: The number of hematopoietic stem cell transplants (HSCTs) performed in the United States and worldwide is increasing. Cardiac events have been well described in HSCT, and the incidence and type of cardiac events have not changed over recent decades. PATIENTS AND METHODS: This study adds to the body of evidence in describing the incidence and type of cardiac events experienced by an allogeneic and autologous HSCT population at a single institution from 2012 to 2017. RESULTS: Sixty-five (9.8%) patients experienced cardiac events, including atrial arrhythmia (N = 39), acute heart failure (N = 9), acute coronary syndrome (N = 7), and new onset hypertension (N = 9), with a few instances of bradycardia, ventricular arrhythmia, pericardial effusion, and pericarditis. Our multivariable regression analysis identified age (older), creatinine (higher), and history of coronary artery disease to significantly correlate with risk of cardiac event (P = .005, P = .039, and P = .038, respectively). A subgroup analysis of those patients experiencing a cardiac event found pre-transplant atrial dilation by trans-thoracic echocardiogram to correlate with increased risk of atrial arrhythmia (33.8% vs. 9.7%; P = .03). Patients developing a CE had an increased risk of death within 1 year (11% vs. 32%; P < .001). CONCLUSION: We review our results in context of other important HSCT cardiac studies to illuminate the most relevant factors of medical history, laboratory data, and cardiac measurements that will identify patients at higher risk, allowing for intervention to improve HSCT outcomes.

Cardiac side effects of targeted therapies.

OBJECTIVES: To review common cardiac side effects, their clinical presentation, and recommendations for assessment and management of patients receiving molecularly targeted cancer therapies. DATA SOURCES: Peer-reviewed literature. CONCLUSION: Although there is no established guideline for pretreatment cardiac evaluation and monitoring of patients receiving molecularly targeted agents, data currently supports the need for early risk identification and prevention/reduction strategies. IMPLICATIONS FOR NURSING PRACTICE: As nurses, we have a unique opportunity to help improve and maintain the quality of life of cancer survivors. Cardiovascular assessment and prevention/reduction strategies are essential to reduce risk of cardiovascular disease, promote optimal quality of life, and improve survival outcomes in patients receiving molecularly targeted cancer treatment.
