1 in 6 Australians report living with cardiovascular disease (heart disease) making heart health an important factor your doctor considers when treating your lymphoma.
Some lymphoma treatments can increase the risk of heart disease including:
Radiotherapy that is delivered close to a person’s heart (eg chest area)
Chemotherapy agents called anthracyclines eg
Doxorubicin
Immune Check point inhibitors eg pembrolizumab
Targeted therapies- eg some BTKi inhibitors such as ibrutinib
Your doctor will ensure that your heart is functioning at an acceptable level before prescribing treatment that may affect your heart. However, exposure to many of these agents even in people with healthy hearts can still cause damage to the heart muscle and increase the risk of heart disease including:
Decreases in the heart’s Left Ventricular Ejection (how much blood the heart pumps with each contraction)
Arrhythmias (irregular heart rate)
Cardiomyopathies (difficult for heart to pump blood)
Hypertension (high blood pressure)
Cardiac ischemia (reduced oxygen to the heart)
Congestive
heart failure (heart has difficulty pumping blood and oxygen around the body)
Heart disease can develop:
Acutely (during or shortly after treatment), or
Chronically (within a year of completing treatment or in the years following treatment)
Common symptoms of heart disease can include:
Difficulty breathing or shortness of breath
Chest pain
Changes to your heart rate or feeling your heartbeat more than usual (palpitations)
Changes to your blood pressure
Dizziness
Swelling in your arms or legs
Extreme tiredness (fatigue).
If you have any of the above symptoms it is important to check in with your GP, cardiologist or treating haematologist. Report any new changes to your doctor, even if you finished treatment months, or years ago. Let them know you had treatment for lymphoma in the past, that may increase your risk of heart disease. Call an ambulance on 000 (Australia) if you have chest pain, pressure in your chest or severe shortness of breath.
Management:
The management of heart disease will depend on the type of treatment you had, and the type of heart disease you have.
You may simply need a smaller dose of the medicine causing problems. Your doctor may also choose to remove or swap a medicine for one less likely to cause damage to your heart.
In certain circumstances you may need to be referred to a Cardiologist (heart specialist). They will then be able to assess and manage your heart disease.
