Symptoms of dilated cardiomyopathy

Common symptoms include:

• Shortness of breath, especially when you exert yourself

• Unexplained tiredness

• Fluid buildup causing swollen feet or ankles or unexplained weight gain

• Heart skipping beats, fluttering, or thumping

• Fainting, dizziness, or lightheadedness

• Swelling of the veins of the neck

When you have dilated cardiomyopathy

With dilated cardiomyopathy, the heart muscle has been damaged. A damaged heart muscle can't pump as much blood as a normal heart. To try to pump enough blood, the heart muscle stretches so it can hold more. The chambers, especially on the left side of the heart, often get larger (dilate). Larger chambers may help move more blood for a while. But in time, the stretched-out muscle gets even weaker and tires out. This causes problems with sending blood to the rest of your body. It makes it harder for your heart to work.

Treatment for dilated cardiomyopathy

Dilated cardiomyopathy often doesn’t go away. But it can be treated. Treatment can help keep cardiomyopathy from getting worse. It can also ease your symptoms. Treatment can also help prevent:

• Worse heart failure

• Blood clots

• Heart valve problems

• Heart rhythm problems

Your healthcare provider will work with you to develop a treatment plan. The aim of the plan is to help you feel better now and prevent problems in the future. Most often, the symptoms can be managed by medicines and lifestyle changes. Some people have severe symptoms. They need to go into the hospital. They may need advanced treatments, such as mechanical assist devices or a heart transplant.

Following your treatment plan

Your treatment plan may include:

• Making lifestyle changes, such as balancing activity and rest, quitting smoking, and tracking your weight

• Eating less salt, as advised

• Taking all medicines as prescribed by your healthcare provider

• Limiting or giving up alcohol

• Keeping track of how you feel in a journal

Call your provider right away if you have symptoms that are getting worse.

See your healthcare provider regularly. Talk about any problems you are having with your treatment plan. Be honest if you are not doing something your provider has suggested. They may be able to make some changes to help your plan work better for you.
