Cardiopulmonary syndromes are heart and lung symptoms, such as dyspnea (shortness of breath), cough, chest pain, irregular heartbeats, and excess fluid around the lungs (pleural effusion) and/or heart (pericardial effusion). These may be caused by cancer or by other conditions. Four cardiopulmonary syndromes commonly caused by cancer are covered in this summary:

• Dyspnea.
• Malignant pleural effusion.
• Malignant pericardial effusion.
• Superior vena cava syndrome.

Glossary Terms

A term for diseases in which abnormal cells divide without control. Cancer cells can invade nearby tissues and can spread to other parts of the body through the blood and lymph systems. There are several main types of cancer. Carcinoma is cancer that begins in the skin or in tissues that line or cover internal organs. Sarcoma is cancer that begins in bone, cartilage, fat, muscle, blood vessels, or other connective or supportive tissue. Leukemia is cancer that starts in blood-forming tissue such as the bone marrow, and causes large numbers of abnormal blood cells to be produced and enter the blood. Lymphoma and multiple myeloma are cancers that begin in the cells of the immune system. Central nervous system cancers are cancers that begin in the tissues of the brain and spinal cord.

Having to do with the heart and lungs.

Difficult, painful breathing or shortness of breath.

Liquid.

One of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body.

Cancerous. Malignant tumors can invade and destroy nearby tissue and spread to other parts of the body.

An abnormal collection of fluid inside the sac that covers the heart.

An abnormal collection of fluid between the thin layers of tissue (pleura) lining the lung and the wall of the chest cavity.

A condition in which a tumor presses against the superior vena cava (the large vein that carries blood from the head, neck, arms, and chest to the heart). This pressure blocks blood flow to the heart and may cause coughing, difficulty in breathing, and swelling of the face, neck, and upper arms.

An indication that a person has a condition or disease. Some examples of symptoms are headache, fever, fatigue, nausea, vomiting, and pain.

A set of symptoms or conditions that occur together and suggest the presence of a certain disease or an increased chance of developing the disease.
