Treatment

If you have heart failure, your doctor will monitor you closely. This means having follow up appointments at least every 3 to 6 months, figuring out any underlying cause and treating it, and periodic testing of your heart function. For example, an ultrasound of your heart, called an echocardiogram, will be done once in awhile to give an estimate of how well your heart is pumping blood with each stroke or beat.

It is also your responsibility to carefully monitor yourself and help manage your condition. One important way to do this is to track your weight on a daily basis. Weight gain can be a sign that you are retaining fluid and that the pump function of your heart is worsening. Make sure you weigh yourself at the same time each day and on the same scale, with little to no clothes on.

Other important measures include:

• Take your medications as directed. Carry a list of medications with you wherever you go.
• Limit salt and sodium intake.
• Don’t smoke.
• Stay active. For example, walk or ride a stationary bicycle. Your doctor can provide a safe and effective exercise plan based on your degree of heart failure and how well you do on tests that check the strength and function of your heart. DO NOT exercise on days that your weight has gone up from fluid retention or you are not feeling well.
• Lose weight if you are overweight.
• Get enough rest, including after exercise, eating, or other activities. This allows your heart to rest as well. Keep your feet elevated to decrease swelling.

Here are some tips to lower your salt and sodium intake:

• Look for foods that are labeled “low-sodium,” “sodium-free,” “no salt added,” or “unsalted.” Check the total sodium content on food labels. Be especially careful of canned, packaged, and frozen foods. A nutritionist can teach you how to understand these labels.
• Don’t cook with salt or add salt to what you are eating. Try pepper, garlic, lemon, or other spices for flavor instead. Be careful of packaged spice blends as these often contain salt or salt products (like monosodium glutamate, MSG).
• Avoid foods that are naturally high in sodium, like anchovies, meats (particularly cured meats, bacon, hot dogs, sausage, bologna, ham, and salami), nuts, olives, pickles, sauerkraut, soy and Worcestershire sauces, tomato and other vegetable juices, and cheese.
• Take care when eating out. Stick to steamed, grilled, baked, boiled, and broiled foods with no added salt, sauce, or cheese.
• Use oil and vinegar, rather than bottled dressings, on salads.
• Eat fresh fruit or sorbet when having dessert.

Your doctor may consider prescribing the following medications:

• ACE inhibitors such as captopril and enalapril -- these medications open up blood vessels and decrease the work load of the heart. These have become an important part of treatment
• Diuretics -- there are several types including thiazide, loop diuretics, and potassium-sparing diuretics; they help rid your body of fluid and sodium.
• Digitalis glycosides -- increase the ability of the heart muscle to contract properly; prevent heart rhythm disturbances
• Angiotensin receptor blockers (ARBs) such as losartan and candesartan which, like ACE inhibitors, reduce the workload of the heart; this class of drug is especially important for those who cannot tolerate ACE inhibitors
• Beta-blockers -- this is particularly useful for those with a history of coronary artery disease

Sometimes, hospitalization is required for acute CHF. Hospitalized patients may receive oxygen and intravenous medications such as vasodilators and diuretics. Medicines such as nesiritide (Natrecor) help dilate blood vessels and may also be helpful.

Medicines called inotropic agents help improve the heart's ability to pump blood. Such drugs include dobutamine and milrinone. They are given by IV.

Unstable patients receiving several medications usually need also hemodynamic monitoring with Swan-Ganz catheterization.

Severe cases of CHF require more drastic measures. For example, excess fluid can be removed through dialysis, and circulatory assistance can be provided by implanted devices such as the intra-aortic balloon pump (IABP) and the left ventricular assist device (LVAD). These devices can be life-saving, but they are not permanent solutions. Patients who become dependent on circulatory support will need a heart transplant.

A number of studies have shown that heart failure symptoms can be improved with a special type of pacemaker. It paces both the right and left sides of heart. This is referred to as biventricular pacing or cardiac resynchronization therapy. Ask your provider if you are a candidate for this.

Expectations (prognosis)

Heart failure is a serious disorder that carries a reduced life expectancy. Many forms of heart failure can be controlled with medication, lifestyle change, and correction of any underlying disorder. Heart failure is usually a chronic illness, and it may worsen with infection or other physical stressors.
