In rheumatic fever damage to the heart valves is directly caused by what?

Answer 1

it uses bacteria and mouse urine and then spreads to the legs and then body

Answer 2

Carditis or inflammation of the heart muscle. this condition can lead to congestive heart failure , shortness of breath, pericardium with a rub, or a new heart murmur.

Migratory poly Arthritis: a temporary migrating form of arthritic inflammation mainly in the large joints, starting in the legs and working its way upwards.

Sydenham's chorea (St. Vitus' dance): rapid movements without purpose of the face and arms. This can occur very late in the disease.

Erythema marginatum: an enduring rash beginning on the trunk or arms as macules and spreading outwards to form a snakelike ring while clearing in the middle. This rash never starts on the face and is becomes worse with heat.

Subcutaneous nodules (a form of Aschoff bodies): painless, firm collections of collagen fibers on the back of the wrist, the outside elbow, and the front of the knees. These now occur infrequently.

Fever:

Arthralgia:

Increased ESR and increased C reactive protein, leukocytosis

Electrocardiogram abnormalities: a prolonged PR interval

Evidence of Group A Strep infection: positive culture for Group A Strep, elevated or rising Antistreptolysin O titre

Previous rheumatic fever or inactive Heart disease

Answer 3

The bacteria responsible for rheumatic fever is part of a group known as Group A streptococcus.

Doctors and researchers recognize the bacteria responsible for rheumatic fever, however they still do not understand exactly what leads to development of this disease. A person can get rheumatic fever as the result of a strep throat infection that is not treated or if a person fails to finish the full 10-day course of antibiotics.

It is possible to get streptococcal infections with no symptoms and it is in these situations in particular that complications may arise such as rheumatic fever.

Rheumatic fever seems to be an autoimmune disease, That is, the body's own immune system produces antibodies that attack its own cells. this leads to rheumatic fever.

Answer 4

Rheumatic fever damages the heart valves through an autoimmune response triggered by a preceding streptococcal infection. The immune system mistakenly attacks the heart valves, leading to inflammation and scarring, which can impair valve function over time.

Answer 5

In rheumatic fever the damage to the heart valves is caused by the protein antibodies. These antibodies are produced to defend against the bacteria.

Answer 6

the hert

Answer 7

kill you.
