Link Between Heart Disease and Cancer Treatment

Cancer survivors are more likely to have cardiovascular disease risk factors, scientists need to develop more effective treatments with fewer side effects.

Cancer treatments such as chemotherapy, radiation treatments and some cancer drugs pose serious long-term damage to the heart. To mitigate these risks, specialists from cardiology and oncology often collaborate when treating cancer patients.

The field of cardio-oncology formed in response to both the increasing number of cancer survivors and the critical need for clinicians to consider the chronic and long-term adverse effects of treatment on patients. For example, heart failure—developing during or after completion of cancer treatment—is a well-recognized complication that can impact a patient’s survival and quality of life. In fact, individual cardiovascular risk factors like hypertension in a cancer survivor appear to carry greater risk than hypertension in an individual without a history of cancer.

What is a Heart Attack | How to Prevent Heart Attacks - Myocardial Infraction Smoking
Heart attack is the death of the heart muscle due to loss of blood supply. Simple guidelines to avoid heart attack are listed.

‘Cancer survivors have an increased risk of cardiovascular disease (CVD) and death due to CVD in all age groups.’

With this research in mind, the main goals of cardio-oncology are to screen for and actively manage modifiable cardiovascular risk factors in cancer patients. For patients determined to be at high risk for developing heart disease, it is critical to implement strategies that focus on early detection of cardiotoxicity, or damage to the heart. These strategies can include:

Referral to a cardio-oncologist as early as possible after diagnosis

Obtaining an echocardiogram — a diagnostic cardiac ultrasound — before beginning treatment for cancer

Routinely assessing patients for clinical signs and symptoms that raise concerns about possible cardiac dysfunction

A cancer patient’s clinical team should regularly evaluate and manage any cardiovascular risk factors. A heart-healthy lifestyle should be discussed as a part of long-term follow-up care. Fortunately, following a heart-healthy lifestyle doesn’t require hours of grueling exercise or giving up all of your favorite foods. A few simple lifestyle changes, such as the ones listed below, can make all the difference. Exercise 30 to 60 minutes a day on most days of the week. This can be as simple as taking a daily walk.

Test your Knowledge on Heart Healthy Diet
Heart disease is the leading cause of death - it claims more lives than all forms of cancer combined. Eating right is an important step towards preventing heart disease. In addition to regular physical activity, being careful about what you eat can help lower cholesterol, control blood pressure and blood sugar levels, and maintain a healthy weight. A heart-healthy diet can reduce the risk of heart attack by 80%. Changing the overall eating pattern is important than obsessing over a single food. Incorporate a variety of healthy foods prepared in healthy ways to prevent and manage heart disease.

Maintain a healthy weight.

Quit or don't start smoking.

Cancer Prevention thro' Lifestyle Changes
Did u know that simple changes in lifestyle could lower your cancer risks? Find out how!

Eat a diet rich in fruits, vegetables, whole grains, nuts and legumes, limiting highly refined carbohydrates and saturated fats.

If you are currently undergoing cancer treatment, be sure to ask your oncologist if you are receiving any therapies that could affect your heart now or in the future. And, if you have a history of receiving cancer-treating radiation to the chest, it is important to know if that raises your risk for heart disease.

The Cardio-Oncology Program at Valley–Mount Sinai Comprehensive Cancer Care brings together Valley Medical Group’s cardiologists and oncologists in an integrated effort to provide specialized care and to protect heart health throughout cancer treatment.
