Impact of Cancer Treatment on Cardiovascular Disease

Introduction:

People facing heart problems are ordinary nowadays. The severe side effect of the heart problem is due to the cancer treatment. The medical term for cancer treatment in the heart is known as cardiotoxicity. Cancer treatment's dose, type, and quality affect the heart in many ways. The impact of cancer treatment causes several side effects, and sometimes it may cause death. Recently, the advancement in cancer treatment has reduced the side effects and death rate and increased the survival rate for cancer individuals. The condition is not common in people with cancer patients who receive chemotherapy and radiotherapy. The condition also develops several years after cancer treatment. Around 5 to 15 percent of cancer patients may develop heart failure after cancer treatment. It also increases the chances of stroke. In the United States, advancements like pacemaker devices can standardize heart damage in cancer-treated people. The article discusses cancer treatment, its effects on the heart, and its side effects.

What Is Cancer Treatment?

Cancer treatment is a medical treatment used to treat various cancers. The treatment is used to kill cancer cells and decrease the spread of cancer to other body organs. The treatment choice depends on the patient's choice, health, and the cancer stage. Common cancer treatment includes surgery, chemotherapy, and radiation therapy. Other cancer therapies include immunotherapy, targeted therapy, hormone therapy, and stem cell transplantation.

What Are the Causes and Risk Factors of Cardiovascular Complications During Cancer Treatment?

Several causes and risk factors associated with cardiovascular complications during cancer treatment are as follows:

• Age: Old age is the leading risk factor for cancer patients and cardiovascular disease. Old-age people are more likely to get cardiovascular complications.

• Cancer Type and Stage: During treatment, certain cancers, such as breast cancer and lymphomas, are more likely to cause cardiovascular complications.

• Genetic Factors: Certain genetic factors are more susceptible to cardiovascular complications during cancer treatment.

• Lifestyle Factors: Certain lifestyle factors such as obesity, poor diet, smoking, and alcohol increase the risk of cancer and cardiovascular disease. These also increase the threat of cardiovascular complications during cancer treatment.

• Cumulative Dose of Cancer Treatment: The dose of cancer treatment, such as chemotherapy drugs, increases the likelihood of developing cardiovascular complications.

• Treatment Field and Radiation Dose: The increased radiation dose during radiation therapy to the chest area increases the risk of affecting the heart and blood vessels. It ultimately increases the chances of getting cardiovascular complications.

• Pre-Existing Cardiovascular Conditions: People with pre-existing conditions such as stroke, heart failure, coronary artery disease, and hypertension increase the threat of developing cardiovascular complications. Some conditions like stress and smoking exacerbate the above conditions.

• Cardiotoxicity of Cancer Treatment: Chemotherapy drugs such as Anthracyclines can lead to heart failure and cardiomyopathy.

What Are the Cancer Treatments That Have an Impact on Cardiovascular Disease?

The cancer treatments that have an impact on cardiovascular diseases are as follows:

• Chemotherapy: Certain chemotherapy drugs, such as Doxorubicin can affect the heart blood vessels. The tyrosine kinase inhibitors can affect the heart and lead to the formation of hypertension or arterial thromboembolism.

• Radiation Therapy: The therapy leads to the formation of pericardial disease, heart failure, and valvular heart disease. The treatment and radiation dose further exacerbate the complications.

• Targeted Therapy: Therapy such as tyrosine kinase inhibitors and monoclonal antibodies increase the chances of developing heart complications such as impaired heart function, thromboembolism, and hypertension.

• Immunotherapy: The therapy is linked with immune-related adverse effects. Cardiovascular complications include myocarditis (inflammation of the muscle of the heart), vasculitis (blood vessel inflammation), and pericarditis (pericardium inflammation).

Does Undergoing Chemotherapy Elevate the Likelihood of Experiencing Heart Complications?

Indeed, certain traditional chemotherapy medications employed in cancer treatment may heighten the potential for heart-related issues. Newer targeted therapy drugs and radiation therapy can also lead to occurrences of heart problems. Heart-related issues that may arise from cancer treatments include the following examples:

• Hypertension.

• Stroke.

• Blood clots.

• Arrhythmia.

• Cardiomyopathy.

• Heart attack.

The likelihood of an individual facing heart problems during and after cancer treatment depends on the overall health of their heart and the specific drugs administered. In individuals with preexisting heart conditions, certain drugs may pose an increased risk of heart problems.

How Does Cancer Treatment Affect Cardiovascular Health?

The cancer treatment causes various cardiovascular side effects. The ways through which cancer treatment has an impact on cardiovascular health are as follows:

• Cardiotoxicity: The chemotherapy drugs can affect or damage the heart muscle and blood vessels. This can lead to heart failure and weakened heart muscle. The drug can interfere with the normal functioning of the heart and affect the heart pumping system.

• Radiation-Induced Cardiovascular Damage: Radiotherapy affects the heart structures leading to heart complications. The symptoms include narrowing of blood vessels, inflammation, and fibrosis.

• Vascular Toxicity: The targeted therapy affects the blood vessels. Some drugs can cause high blood pressure, the formation of blood clots in arteries, and impaired heart function. These drugs also disrupt the vascular health pathways, maintaining the average balance.

• Indirect Effects: Cancer treatment's other indirect effects include low blood cell count. Additionally, stress and pre-existing cardiovascular conditions affect or exacerbate the conditions.

How to Prevent the Impact of Cancer Treatment on Cardiovascular Disease?

Preventive measures should be adopted by the people to minimize the risk and to manage complications as follows:

• Cardiologist and Oncologist Collaboration: Patient care can be optimized by collaboration between the oncologist and the cardiologist. Regular communication and decision-making between them help identify patients at high risk of cardiovascular complications.

• Pre-treatment Assessment: The patient should be evaluated before the start of cancer treatment. This will help in identifying pre-existing heart conditions and improvised treatment planning.

• Risk Assessment: The assessment helps identify the people at high risk of cardiovascular complications.

• Medications: The doctor may prescribe medications to reduce the impact of cancer treatment. The medications include beta blockers and ACE inhibitors.

• Monitoring: Proper monitoring of cardiovascular health during cancer treatment is necessary. This can be done by magnetic resonance imaging and managing blood pressure levels.

• Lifestyle Changes: People should adopt lifestyle changes such as smoking cessation and limiting stress which could help reduce the harmful impact of cancer treatment on cardiovascular diseases.

Conclusion:

Cancer treatment hurts cardiovascular health. Chemotherapy drugs affect the heart muscles and blood vessels. It disrupts the regular pumping system of the heart. Stress, smoking, and alcohol intake further exacerbate heart complications. Individuals with pre-existing heart disease and taking chemotherapy treatment are at high risk of cardiovascular complications. Certain medications, monitoring of patients, and lifestyle changes can prevent the impact of cancer treatment on cardiovascular diseases.
