Question

in a young and otherwise healthy patient who has not had an MI, suspect ___ as the cause of acute mitral regurgitation

Answer 1

Acute mitral regurgitation in a young, healthy patient without history of MI may be caused by conditions such as infective endocarditis or valvular disorders such as mitral valve prolapse.

Step-by-step explanation:

In a young and otherwise healthy patient who has not had a myocardial infarction (MI), infective endocarditis or severe valvular disorders such as mitral valve prolapse could be suspected as the cause of acute mitral regurgitation. Mitral regurgitation is a common valve disorder and is often due to the malfunctioning of the valve which disrupts the flow of blood, leading to mitral insufficiency.

While rheumatic fever, a disease typically of childhood, is one common cause of valvular disorders, in young adults without a history of MI, other causes such as infective endocarditis should be considered.
