It is no secret that radiation therapy and certain cancer drugs, while showing effectiveness in killing cancer cells, can have toxic and damaging effects on the rest of the body including the heart.
An article published in the American College of Cardiology (ACC) references that chemotherapy can cause pulmonary dysfunction, anemia, skeletal muscle and cardiomyocyte dysfunction, endothelial dysfunction, and arterial stiffness.1 The article goes on to include that patient factors including presence of comorbidities and lifestyle factors, such as physical inactivity, excess body weight, and tobacco use also impact cardiovascular reserve. “From a cardiology perspective it’s recommended that we first identify patients who are at high risk,” says Dr. Mansson. “We also work with oncologists to help monitor cardiotoxity, avoid dose interruptions and prevent cardiac events.” Dr. Mansson points out that there is a guideline document that is followed according to the dosage of chemo and amount of radiotherapy given to patients.
Developing strategies prior to breast cancer therapy play a role in managing the risk of heart damage. “As clinicians, we can provide a comprehensive assessment prior to potentially cardiotoxic therapies, and recommendations by the ACC have been to avoid or minimize use of potentially cardiotoxic therapies if established alternatives exist that would not compromise cancer specific outcomes,” says Dr. Mansson.
Dr. Mansson emphasizes that certain lifestyle choices can help combat heart disease risk factors.
These include:
• Maintaining a healthy weight
• Refraining from smoking
• Stress reduction techniques (meditation, yoga)
• Eating a healthy diet low in saturated fat, cholesterol and salt, and staying away from refined carbohydrates
• Exercising 30-60 minutes, most days of the week
While damage to the heart can be an issue among breast cancer patients seeking treatment, this should not deter them from undergoing treatment. Making informed decisions with your healthcare provider is important in creating the best strategy to fight breast cancer and protect your heart at the same time.
