Summary Introduction
To explain: The way by which rheumatic fever affects the functioning of heart.
Introduction: The disease caused by an autoimmune response to a bacterial infection with group A Streptococcus is called as acute rheumatic fever. Rheumatic heart diseases refer to a group of acute and chronic heart disorders that occur as a result of acute rheumatic fever. Acute rheumatic fever occurs when the connective tissues of the body are swollen.

- Valve regurgitation is yet another condition causing heart failure. This condition is characterized by _________________. 1)the hardening of a valve, narrowing the opening that serves as a passage of blood. 2) a valve that everts back into the previous chamber, blockig blood from progressing into the ventricle. 3) a valve that does not close completely, and allows blood to leak back into the previous chamber. 4)a valve with an opening that is too narrow, not allowing for sufficient blood to travel to the next chamber.arrow_forwardOne treatment for heart problems is “bypass surgery.” What is this and why is it done?arrow_forwardWhy do cardiac enzymes rise after an acute myocardial infarction? a) Cardiac enzymes leak from the damaged muscle fibers into the bloodstream.
