What is Cardiomegaly?

A cardiomegaly or an enlarged heart is a medical condition in which the heart is enlarged. It may have various causes but, often it is the result of high blood pressure (hypertension) or the coronary artery disease. An enlarged heart may not pump the blood effectively, resulting in congestive heart failure. Cardiomegaly may improve over time, but most people with an enlarged heart needs lifelong treatment with medications.

Types of Cardiomegaly:

The heart enlarges in response to the damage of the heart muscle. Up to a point, an enlargement permits the heart to continue pumping the blood normally. But as the enlargement progresses, the pumping ability of the heart declines.

Dilated cardiomyopathy is the main type of cardiomegaly where the walls of both the left and right side of the heart (ventricles) become thin and stretched. This results in an enlarged heart..

In other types of enlarged heart, the muscular left ventricle of the heart becomes abnormally thick. High blood pressure causes the left ventricular enlargement, also called as hypertrophy, while the hypertrophic cardiomyopathy is an inherited condition. Generally speaking, the pumping ability of the heart is preserved better, when the enlarged heart is thick rather than thin.

Causes of Cardiomegaly:

The most common causes of an enlarged heart include the blockages in the blood supply (coronary heart disease) and high blood pressure.

Other causes of cardiomegaly include:

  • Abnormal heart valve
  • Viral infection of the heart
  • Kidney disease requiring dialysis
  • Pregnancy with enlarged heart developing around the time of delivery (peripartum cardiomyopathy)
  • HIV infection
  • Alcohol or cocaine abuse
  • Genetic and inherited conditions

Frequently, when no cause for an enlarged heart is identified, then it is known as idiopathic dilated cardiomyopathy.


Most often, cardiomegaly or an enlarged heart causes no symptoms. If an enlarged heart becomes unable to pump the blood effectively, the symptoms of a congestive heart failure can develop.

  • Palpitations or skipped heartbeats
  • Shortness of breath (especially with exertion or when lying flat)
  • Increased abdominal girth
  • Leg swelling
  • Fatigue
  • Weight gain
  • Chest pain
  • Fainting

The symptoms of cardiomegaly may vary widely in people. Some people may never have symptoms while others may have mild symptoms that remain unchanged for years. Some people may experience steadily worsening shortness of breath.


After a person discusses the symptoms of a congestive heart failure, cardiomegaly may be discovered. Other times, it may be discovered in people without any symptoms who gets a test for other reasons. Doctors may ask your medical history to get the initial clues regarding the presence of cardiomegaly. He/she may perform a physical exam wherein, the doctor will use the stethoscope to listen the abnormal sounds that are produced by the enlarged heart.

  • Echocardiography: Also known as the ultrasound of the heart, it is the preferred test to diagnose an enlarged heart. It can accurately measure the heart’s size, pumping function and muscle thickness. There is no pain or risk from an echocardiogram. In certain cases, it can actually suggest the potential causes for a cardiomegaly.
  • Cardiac catherization: This procedure is used to detect the blockages in the coronary arteries, the pumping function and size of the heart is checked.
  • Chest X-ray: The dilated cardiomyopathy is a type of cardiomegaly, produces an abnormally large shadow on a chest X-ray film.
  • CT scans and MRIs: They help to diagnose an enlarged heart in certain situations.
  • Blood tests: These are done to check the causes of an enlarged heart like:
    • Thyroid disease
    • Congestive heart failure
    • HIV or other viral infection
  • Biopsy: Your doctor may recommend taking a small tissue sample from inside your heart to determine the cause of cardiomegaly.


The treatments for cardiomegaly focuses on the underlying cause such as:

  • Hypertension
  • Coronary artery disease
  • Heart valve disease
  • Alcohol, drug or medication use

Other treatments like medication treatment and the medical/surgical procedures focus on improving the symptoms and maintaining the heart function. Below are some treatment options for individuals with cardiomegaly:


  • Angiotensin-converting enzyme (ACE) inhibitors: It lowers your blood pressure and improves the pumping ability of your heart.
  • Diuretics: To lower the amount of sodium and water in your body that can help to lower the pressure in your arteries and heart.
  • Angiotensin receptor blockers (ARBs): It provides the benefits of ACE inhibitors for those who can’t take the ACE inhibitors.
  • Digoxin: It helps to improve the pumping function of your heart and lessen the need for hospitalization due to heart failure.
  • Beta blockers: It lowers the blood pressure and improves your heart function.
  • Anti-arrhythmics: It helps to keep your heart beating with a normal rhythm.
  • Anticoagulants: It reduces the risk of blood clots that could cause a heart attack or stroke.

Medical Devices to Regulate Your Heart Beat:

Pacemaker: It coordinates the contractions between the left and right ventricle. Individuals who are at risk of serious arrhythmias, the drug therapy or an implantable cardioverter-defibrillator (ICD) may be used. ICDs are small devices implanted in your chest to constantly monitor your heart rhythm and deliver the electrical shocks when required to control the rapid, abnormal heartbeats. These devices may also work as a pacemaker.

Surgical Procedures:

  • Coronary bypass surgery: If your cardiomegaly is related to the coronary artery disease, then you may opt for the coronary bypass surgery.
  • Heart valve surgery: If your enlarged heart is caused due to problems in one of your heart valves, then surgery is required to remove the valve and replace it with either an artificial valve or a tissue form cow, pig or a deceased human donor. If the blood leaks backward through your valve, then the leaky valve may be surgically repaired or replaced.
  • Left ventricular assist device (LVAD): This implantable mechanical pump helps your weak heart pump. Often, the LVAD are implanted while you wait for a heart transplant or if you are not a heart transplant as a long-term treatment for the heart failure.
  • Heart transplant: If the medications can’t control your symptoms, then a heart transplant is often a final option.
