    Cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Cardiomyopathy is disease in which the heart muscle becomes weakened, stretched, or has another structural problem. It often occurs when the heart cannot pump or function well. Most people with cardiomyopathy have .

    Digoxin test

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    A digoxin test checks to see how much digoxin you may have in your blood. Digoxin is a type of medicine called a cardiac glycoside. It is used to treat certain heart problems. See also:

    Dilated cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Dilated cardiomyopathy is a condition in which the heart becomes weakened and enlarged. As a result, the heart cannot pump enough blood to the rest of the body. There are many types of cardiomyopathy. Dilated cardiomyopathy is the most common form. Some experts use the term “dilated ...

    Echocardiogram

    Blood used by the body is brought back to the heart and lungs by the veins of the body.  Once the blood has gathered more oxygen from the lungs, it is pumped back out to the  body through the arteries.

    An echocardiogram is a test that uses sound waves to create pictures of the heart. The picture is more detailed than a standard image. An echocardiogram does not expose you to radiation.

    Heart Failure Overview

    The abnormal buildup of fluid in the body is called edema. Edema is commonly seen in the feet and ankles, because of the effect of gravity, swelling is particularly noticeable in these locations. Common causes of edema are prolonged standing, prolonged sitting, pregnancy, being overweight, and increase in age.

    Heart failure is a condition in which the heart is no longer able to pump out enough oxygen-rich blood. This causes symptoms to occur throughout the body.

    Heart MRI

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Heart (MRI) is an imaging method that uses powerful magnets and radio waves to create pictures of the heart. It does not use radiation (x-rays). Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces dozens or sometimes hundreds of ...

    Hypertrophic cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Hypertrophic cardiomyopathy (HCM) is a condition in which the heart muscle becomes thick. Often, only one part of the heart is thicker than the other parts. The thickening can make it harder for blood to leave the heart, forcing the heart to work harder to pump blood. It also can make it harder for ...

    Left heart ventricular angiography

    Left heart ventricular angiography is a procedure to look at the left side of the heart and, sometimes, the coronary arteries.

  • Test

    Nuclear ventriculography

    During the MUGA test, a radioactive isotope is injected into the vein. Radioactive isotopes attach to red blood cells and pass through the heart in the circulation. The isotopes can be traced through the heart using special cameras or scanners. The test is often given at rest, then repeated with exercise, or after administering certain medications. The test is performed to detect certain heart conditions.

    Nuclear ventriculography is a test that uses radioactive materials called tracers to show the heart chambers. The procedure is . The instruments do not directly touch the heart.

    Potassium in diet

    Potassium is a mineral that is needed for your body to work properly. It is a type of .

  • Disease

    Pulmonary edema

    Air is breathed in through the nasal passageways, travels through the trachea and bronchi to the lungs.

    Pulmonary edema is an abnormal buildup of fluid in the lungs. This buildup of fluid leads to shortness of breath.

  • Disease

    Restrictive cardiomyopathy

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Restrictive cardiomyopathy refers to a set of changes in how the heart muscle functions. These changes cause the heart to fill poorly (more common) or squeeze poorly (less common). Sometimes, both problems are present.

  • Test

    Right heart ventriculography

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Right heart ventriculography is a study that images the right chambers (atrium and ventricle) of the heart.

    Sodium in diet

    Sodium is an element that the body needs to function properly to regulate blood pressure and blood volume. For individuals who are sodium-sensitive, an increased intake of sodium may contribute to high blood pressure. When watching the intake of sodium, read labels carefully to determine the total sodium content. Canned, packaged, and frozen foods can be particularly high in sodium.

    Sodium is an element that the body needs to work properly. Salt contains sodium.

    Ventricular assist device

    The interior of the heart is composed of valves, chambers, and associated vessels.

    Ventricular assist devices (VADs) help your heart pump blood from one of the main pumping chambers to the rest of your body or to the other side of the heart. These pumps may be implanted in your body or connected to a pump outside your body.
