How viruses and bacteria attack the heart: The danger lurks on the skin. Streptococci or staphylococci can cause heart inflammation.

Pacemakers and other medical devices are vulnerable to bacteria. It's better to go to the doctor too often rather than too little. People with certain heart diseases should be particularly careful. If you don't cure an infection properly, you weaken your immune system. This makes it more difficult for the body to fight bacteria that it would be able to deal with better in a healthy state.
