Infections and inflammatory heart diseases can cause significant damage to the heart and its surrounding structures. Conditions such as infective endocarditis, myocarditis, and pericarditis result from bacterial, viral, or fungal infections, leading to inflammation and compromised heart function. Myocarditis, for example, occurs when the heart muscle becomes inflamed due to a viral infection, weakening its ability to pump blood effectively. Inflammatory heart diseases can also arise from autoimmune conditions, where the body's immune system attacks its own tissues, including the heart. Early diagnosis through blood tests, imaging, and clinical evaluation is essential for effective treatment, which may include antibiotics, antivirals, or immunosuppressive therapies. Managing these conditions promptly can reduce the risk of long-term heart damage, including heart failure or valve dysfunction.
