Cardiac murmur, level two. What's going on?

Heart murmur grade 2 may be related to heart valve abnormalities, heart vascular abnormalities, myocardial disease, etc.

1. Heart valve abnormalities The

heart valve is responsible for controlling the direction of blood flow to the heart. If the valve is not completely closed or the valve is not completely open, it will cause blood flow to appear grade 2 murmur.

2. Heart vascular abnormalities

Heart vascular abnormalities, such as aneurysms or arterial stenosis, may also cause abnormal turbulence in blood flow, resulting in grade 2 murmur.

3. Myocardial disease

Abnormal changes in the myocardium, such as myocardial hypertrophy and myocardial inflammation, can also affect blood flow, resulting in grade 2 murmur in the heart.
