Cardiomyopathy - peripartum

Definition    Return to top

Peripartum cardiomyopathy is a rare disorder in which a weakened heart is diagnosed within the final month of pregnancy or within 5 months after delivery.

Causes    Return to top

Cardiomyopathy occurs when there is damage to the heart. As a result, the heart muscle becomes weak and cannot pump blood efficiently. Decreased heart function affects the lungs, liver, and other body systems.

Peripartum cardiomyopathy is a form of dilated cardiomyopathy in which no other cause of heart dysfunction (weakened heart) can be identified.

In the United States, peripartum cardiomyopathy complicates 1 in every 1,300 - 4,000 deliveries. It may occur in childbearing women of any age, but it is most common after age 30.

Risk factors include obesity, having a personal history of cardiac disorders such as myocarditis, use of certain medications, smoking, alcoholism, multiple pregnancies, being African American, and being malnourished.

Exams and Tests    Return to top

During a physical examination, the physician will look for signs of fluid in the lungs by touching and tapping with the fingers. Listening to the chest with a stethoscope will reveal lung crackles, a rapid heart rate, or abnormal heart sounds.

The liver may be enlarged and neck veins may be swollen. Blood pressure may be low or may drop when the patient stands up.

Heart enlargement, congestion of the lungs or the veins in the lungs, decreased cardiac output, decreased movement or functioning of the heart, or heart failure may show on:

A heart biopsy may be helpful in determining an underlying cause of cardiomyopathy. Many cases of peripartum cardiomyopathy seem to be related to myocarditis, which can be confirmed by a heart biopsy.

Treatment    Return to top

The woman may need to stay in the hospital until acute symptoms subside.

Because the heart dysfunction is usually reversible, and the women are usually young, everything possible will be done to ensure survival.

This may include taking extreme measures such as:

For most women, however, treatment focuses simply on relieving the symptoms. Some symptoms resolve on their own without treatment.

Medications include:

A low-salt diet may be recommended. Fluid may be restricted in some cases. Activities, including nursing the baby, may be limited when symptoms develop.

Daily weighing may be recommended. A weight gain of 3 or 4 pounds or more over 1 or 2 days may be a sign of fluid build up.

Women who smoke and drink alcohol will be advised to stop, since these habits may make the symptoms worse.

Outlook (Prognosis)    Return to top

There are several possible outcomes in peripartum cardiomyopathy. Some women remain stable for long periods, while others get worse slowly.

Others get worse very quickly and may be candidates for a heart transplant. The death rate may be as high as 25 - 50%.

The outlook is good for women whose hearts returns to normal size after the baby is born. If the heart remains enlarged, future pregnancies may result in heart failure. It is not known how to predict who will recover and who will develop severe heart failure.

Women who develop peripartum cardiomyopathy are at high risk of developing the same problem with future pregnancies and should discuss contraception with their physician.

When to Contact a Medical Professional    Return to top

Call your health care provider if you are currently pregnant or have recently delivered a baby and think you may have signs of cardiomyopathy.

Also seek medical attention if you develop chest pain, palpitations, faintness, or other new or unexplained symptoms.

Prevention    Return to top

Eat a well-balanced, nutritious diet, exercise to increase cardiovascular fitness, and avoid cigarettes and alcohol. Your doctor may advise you to avoid getting pregnant again if you have had heart failure during a previous pregnancy.
