Medications
You probably will need to take a
combination of medicines to treat
heart failure, even if you do not have symptoms yet.
Medicines do not cure heart failure. But they can help you manage your
symptoms.
The goals of drug treatment are to relieve or control
symptoms of heart failure, improve daily function and quality of life, slow the
progression of the disease, and reduce the risk of complications, hospital
stays, and premature death.
Medicines are used to treat the
problems associated with heart failure, including:
- Fluid buildup, swelling, and water retention (edema).
- The reduced pumping ability of the heart.
- The effects of the body's attempt to
compensate for heart failure.
- Other conditions that can lead to heart failure, such as
coronary artery disease, high blood pressure, or
diabetes.
- Prevention of complications, such as
stroke.
It is extremely important that you take your medicines
exactly as recommended by your doctor. If you don't, your heart failure may get
worse or you may develop
sudden heart failure. For more information,

Medicine Choices
A combination of medicines is
often needed to control symptoms and slow the progression of heart failure.
Some medicines are used to treat pumping problems (systolic heart failure), and others are used to treat
problems with filling (diastolic heart failure). The most commonly used and
effective classes of medicines are as follows:
Medicines for pumping problems (systolic heart failure)
These include:
- ACE inhibitors (angiotensin-converting enzyme
inhibitors). ACE inhibitors allow blood vessels to relax and widen (dilate),
making it easier for blood to flow through the vessels.
- ARBs (angiotensin II receptor blockers). Like ACE
inhibitors, ARBs allow blood vessels to relax and widen (dilate), making it
easier for blood to flow through the vessels.
- Diuretics. Diuretics stimulate the kidneys to remove
more water and salt (sodium) from the body.
- Aldosterone receptor antagonists. These medicines
cause the kidneys to get rid of extra salt and fluid, and they help hold on to
(retain) potassium by inhibiting the action of the hormone aldosterone.
- Digoxin. Digoxin slows and strengthens heart
contractions, enabling the heart to pump more blood with each beat.
- Beta-blockers. Beta-blockers control symptoms of heart
failure by either slowing the heart rate or making the blood vessels wider so
blood flows more easily.
- Vasodilators. Vasodilators lower blood pressure and
reduce the workload on the heart. Vasodilators like hydralazine are often used
along with nitrates.
Medicines for filling problems (diastolic heart failure)
If your heart failure is related to another
condition, such as irregular rapid heartbeats (arrhythmias), impaired blood
flow to the heart muscle (ischemia), or high blood pressure, you may take
specific drugs for these conditions.
If you take the anticoagulant warfarin, don't suddenly
change your intake of foods that are rich in vitamin K. Vitamin K can interfere
with the action of anticoagulants, making it more likely that your blood will
clot. For more information, see:
Anticoagulants: Vitamin K and your diet.
What to Think About
Taking medicines used only to
treat diastolic dysfunction may be harmful if you have systolic dysfunction,
and vice versa.
Different people will take different medicines
depending on the cause of heart failure and other related conditions.
Medicines for arthritis can cause sodium and water retention and can make
heart failure worse. Ask your doctor before taking
nonsteroidal anti-inflammatory drugs (NSAIDs), such as
ibuprofen (Advil or Motrin), naproxen (Aleve), or cyclooxygenase-2 (COX-2)
inhibitors, such as celecoxib (Celebrex). For more information, see:
