The pericardium is a thin membrane that surrounds and protects your heart. This membrane helps prevent infection. It also keeps the heart from over-expanding. Certain diseases and health problems can cause an inflammation of this membrane. This is known as pericarditis.
Pericarditis can be caused by
When the inflammation is caused by bacteria, it is called bacterial pericarditis.
This condition occurs when certain bacteria enter the pericardium and cause infection. The most common bacteria that cause bacterial pericarditis are Staphylococci and Streptococci. Other bacteria can also cause this condition, including Pneumococci.
Bacteria can enter the pericardium in a number of ways:
Patients with other health problems are at a greater risk for developing bacterial pericarditis because their bodies are less able to fight the infection. Health problems that may increase your risk for developing this disorder include:
Men aged between 20 and 50 are also more likely to develop this condition. In this group, bacterial pericarditis often develops following a lung infection.
The symptoms of bacterial pericarditis will depend on the severity of your condition. They will also depend on the presence of any underlying health problems.
Other symptoms that may occur with bacterial pericarditis include:
Bacterial pericarditis can be diagnosed by your doctor. He or she will perform a physical exam to see if you have the above symptoms. In particular, your doctor will use a stethoscope to listen to the sounds in your chest. If you have bacterial pericarditis, your doctor will be able to detect what is known as a pericardial rub. This sound occurs when the layers of the infected pericardium rub together.
Your doctor may also check to see if you have
If you have any of these conditions, your doctor will order additional tests to confirm your diagnosis. These include
If you have pericarditis, your doctor will need to determine if it is caused by bacteria. To do this, your doctor may order tests to detect the presence of harmful bacteria, including:
Treatment is aimed at curing the infection. Your doctor may recommend bed rest. You will need to elevate your head while lying down. This will reduce strain on your heart.
Your doctor may also prescribe medications, including
In most cases, you will need only medication to treat bacterial pericarditis. If your condition is severe, your doctor may need to use surgical treatments. These can include:
Removal of the pericardium is only done if other treatment does not stop the infection from occurring again. Some people develop a condition known as chronic pericarditis. This means that your infection returns even with treatment or lasts for six months or more.
If left untreated, bacterial pericarditis can be fatal. With proper treatment, you can recover completely. Your outlook will depend on whether you develop any health complications because of this condition.
Complications from this condition can include:
If you develop any of these complications, your outlook may not be as positive. You may also develop chronic pericarditis. If this condition develops, talk to your doctor about your treatment options and what you can expect.
