Study Notes
### Diastolic Function
- Assessed by variables including LAP, E/e', e', DT, and E/A
- LAP refers to left atrial pressure, a measure of pressure in the left atrium.
- Palm veins refers to the visible veins in the palm of the hand, and is not included in the table.
- LAVI represents left atrial volume index, which is the volume of the left atrium adjusted for body surface area.
- Peal TK indicates the peak transmitral flow velocity.
- E/e' represents the ratio of early mitral inflow velocity to early diastolic mitral annular velocity.
- e' refers to the early diastolic mitral annular velocity.
- DT stands for deceleration time, which is the time it takes for the early mitral inflow velocity to decrease to half its peak value.
- E/A represents the ratio of early mitral inflow velocity to late mitral inflow velocity.
### Diagnostic Categories
-
Normal diastolic function is characterized by an LAVI greater than or equal to D, a Peak TK less than or equal to 28 ml/s, an E/e' less than or equal to 8, an e' less than or equal to 8, a DT less than or equal to 200 ms, and an E/A less than or equal to 0.8.
-
Impaired diastolic function is characterized by an LAVI greater than or equal to D, a Peak TK less than or equal to 28 ml/s, an E/e' between 9 and 12, an e' less than or equal to 8, a DT less than or equal to 200 ms, and an E/A between 0.8 and 1.5.
-
Elevated diastolic function is characterized by an LAVI greater than or equal to D, a Peak TK greater than 28 ml/s, an E/e' between 9 and 12, an e' less than 8, a DT less than 200 ms, and an E/A greater than or equal to 2.0.
-
It is important to note that the table only provides a general overview and further references are necessary for detailed classifications.
-
The note regarding "less compliance with E/e'" indicates that E/e' may be less reliable in assessing diastolic function in certain situations.
