Endocarditis

With a bacterial or fungal infection deep in your body several things can happen:

• The valve deteriorates and leaks badly which puts a strain on the heart.
• The infection causes “lumps of inflammation and infection” also known as “vegetations” in which can break off and cause stroke, heart attack or gut and kidney problems depending on where they land.
• An abscess can form in your heart. This means surgery will be needed as antibiotics cannot get into the abscess.
• Septicaemia – the infection can cause you to be very sick, with fever, sweat, and rigors.
• Renal failure – the kidneys can fail as a reaction to inflammation in the body.

It can sometimes be difficult to diagnose endocarditis however when you are generally unwell and have a known valve problem, the suspicion is high and  tests can be carried out to rule it out. Common tests include:

• ECG – if an abscess develops the ECG can change with infection, and ECG will show a fast heart rate.
• Echocardiogram – an Echo from the outside of the body may identify the vegetation, but even a transoesophageal echocardiogram cannot rule out endocarditis and if the resolution is 2mm or so it could miss a small infection.
• Bloods – a blood count, renal function, liver function, and markers of inflammation such as C-Reactive Protein are routinely done. Blood cultures should be taken at least 6 times to be sure any bug is not a contaminant from the skin, but is growing in the bloods.
• Chest X ray – to see if there is lung infection or heart failure.
• CT or MRI head – if you are confused, or have a weak arm or leg, we need to exclude any infection in the brain.

Urine dipsticks – to see if the kidneys are damaged and leaking blood or protein.

Prevention

To reduce your risk of endocarditis consider these:

• Avoid self medicating with the injection of drugs, especially dirty needles.
• Good dental hygiene – many of the bugs that cause endocarditis come from the mouth, especially if you are immunosuppressed or have a known valve problem. It is advised to get regular dental check-ups.
• Consider antibiotics prophylaxis for dental procedures if you have an existing valve problem, have had endocarditis or have a mechanical or tissue artificial valve. You can learn more about artificial heart valves.
• See your GP if you feel very unwell to exclude endocarditis.

Treatment

• Antibiotics –  As with any infection, early use of antibiotics is vital.  These are usually given for 6 weeks to ensure the infection is gone.
• Surgery –  If the antibiotics do not bring the fever down, an abscess is present, or the vegetation are large, surgery may be needed as an emergency. If the valve is damaged but stable, then surgery may be needed at a later stage.
