Myocarditis is an inflammation of the heart muscle (myocardium) typically caused by viral infections, but it can also be the result of bacterial, fungal, or parasitic infections. It can lead to the weakening of the heart muscle and heart failure if not treated. Pericarditis is inflammation of the pericardium (the fibrous sac surrounding the heart) and can also affect heart function, but it generally does not lead directly to muscle weakening. Endocarditis is an infection of the inner lining of the heart chambers and valves, which can also impact heart function but is more likely to cause issues with valve operation rather than direct muscle weakening.
