Cardiovascular Risk Assessment and Management in Cancer Patients Prior to Cancer Therapy

A comprehensive cardiovascular risk assessment including history, physical examination, and screening for cardiovascular risk factors should be performed in all cancer patients before initiating potentially cardiotoxic therapies. 1, 2

Initial Cardiovascular Risk Assessment

Comprehensive Evaluation

  • Perform a thorough history and physical examination to identify pre-existing cardiovascular conditions and risk factors 1, 2
  • Screen for cardiovascular risk factors including hypertension, diabetes, dyslipidemia, obesity, and smoking 1
  • Obtain baseline echocardiogram to assess ventricular ejection fraction and valvular function before initiating potentially cardiotoxic therapies 1, 2
  • Consider baseline cardiac biomarker evaluation (troponin, BNP) in selected high-risk patients, particularly those receiving high-dose cardiotoxic chemotherapy 1

Risk Stratification

  • Identify patients at higher risk for cardiac dysfunction, including those with: 1
    • Multiple cardiovascular risk factors (≥ two risk factors)
    • Older age (≥ 60 years) at cancer treatment
    • Compromised cardiac function (e.g., borderline low LVEF 50-55%, history of myocardial infarction)
    • Planned treatment with high-risk therapies (anthracyclines, HER2-targeted therapies, VEGF inhibitors)

Management Strategies

Risk Factor Modification

  • Actively manage modifiable cardiovascular risk factors in all patients receiving potentially cardiotoxic treatments 1
  • Treat identified cardiovascular risk factors according to current guidelines 1
  • Aggressively control hypertension, especially in patients receiving VEGF inhibitors 2

Treatment Selection and Modification

  • Avoid or minimize cardiotoxic therapies if established alternatives exist that would not compromise cancer-specific outcomes 1, 2
  • Consider cardioprotective strategies for high-risk patients receiving anthracyclines: 1, 2
    • Dexrazoxane
    • Continuous infusion of doxorubicin
    • Liposomal formulation of doxorubicin

Radiation Therapy Considerations

  • For patients requiring mediastinal radiation therapy: 1
    • Select lower radiation doses when clinically appropriate
    • Use more precise radiation fields with exclusion of as much heart as possible
    • Consider techniques like deep-inspiration breath holding for patients with mediastinal tumors or breast cancer
    • Utilize intensity-modulated radiation therapy to precisely contour radiation distribution

Multidisciplinary Collaboration

  • Establish close and early collaboration between cardiologists, oncologists, hematologists, and radiation oncologists 1
  • The multidisciplinary team should aim for a balanced approach to minimize cardiovascular toxicity while limiting reduction or discontinuation of cancer therapy 1
  • Refer patients to cardiology based on concerning findings during assessment 2

Monitoring During and After Treatment

  • Monitor cardiovascular safety throughout cancer treatment, especially with mediastinal/left-sided chest radiation and certain chemotherapy/targeted agents 1
  • Perform regular cardiac surveillance with echocardiography for high-risk patients 2
  • Consider serum cardiac biomarkers or echocardiography-derived strain imaging for enhanced monitoring 2
  • Complete careful history and physical examination in patients receiving potentially cardiotoxic treatments 1
  • For patients who develop clinical signs or symptoms of cardiac dysfunction during treatment, obtain echocardiogram for diagnostic workup 1

Common Pitfalls to Avoid

  • Failing to perform baseline cardiovascular assessment before initiating cardiotoxic therapies 1, 2
  • Overlooking the importance of cardiovascular risk factor management in cancer patients 1
  • Unnecessary discontinuation of cancer therapy without appropriate cardio-oncology consultation 1
  • Inadequate monitoring of patients receiving potentially cardiotoxic therapies 1, 2
  • Neglecting to consider cardioprotective strategies for high-risk patients 1, 2
