In cardiac physiology, the Levine grading scale is a numeric scoring system to characterize the intensity or the loudness of a heart murmur. The eponym is from researcher Samuel A. Levine who studied the significance of systolic heart murmurs. [ 1 ]
There are two types of murmur. A functional murmur is a benign heart murmur that is primarily due to physiologic conditions outside the heart. The other type of heart murmur is due to a structural defect in the heart itself. [1] [5] Defects may be due to narrowing of one or more valves (stenosis), backflow of blood, through a leaky valve ...

Levine's sign is a clenched fist held over the chest to describe ischemic chest pain. [ 1 ] It is named for Samuel A. Levine (1891–1966), an influential American cardiologist , who first observed that many patients with chest pain made this same sign to describe their symptoms.
Bruit, also called vascular murmur, [3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.
Heart disease is consistently the leading U.S. cause of death and accounts for larger medical costs than any other condition. By 2035, the American Heart Association projects that 45% of Americans ...
The loudness of the murmur does not correlate well with the severity of regurgitation. It may be followed by a loud, palpable P 2, [6] heard best when lying on the left side. [7] A third heart sound is commonly heard. [6] Patients with mitral valve prolapse may have a holosystolic murmur or often a mid-to-late systolic click and a late systolic ...
The sign has a sensitivity of 80% for myocardial infarction (MI), i.e. in patients with cardiac pain and a heart attack, Levine's sign was positive in 80%; however, it is not very specific, as the absence of the sign in patients with cardiac pain would falsely miss 51% (Edmonstone 1995). Whether or not the sign is present in all cases of MI ...
