3. Number of Attributes: 12
Attribute Information:
1. (survival) : the number of months patient survived (has survived, if
patient is still alive). Because all the patients had their heart attacks at
different times, it is possible that some patients have survived less than
one year but they are still alive. Check the second variable to confirm
this. Such patients cannot be used for the prediction task mentioned
above.
2. (still-alive) : a binary variable. D=dead at end of survival period, L
means still alive .
3. (age at heart attack) : age in years when heart attack occurred.
4. (pericardial effusion) : binary. Pericardial effusion is fluid. around
the heart. 0=no luid, 1= luid .
5.( fractional shortening ) : a measure of contracility around the heart
lower numbers are increasingly abnormal .
6. (epss) : E-point septal separation, another measure of contractility.
Larger numbers are increasingly abnormal.
7. (lvdd) : left ventricular end-diastolic dimension. This is a measure of
the size of the heart at end-diastole. Large hearts tend to be sick hearts.
8. (wall motion score) : a measure of how the segments of the left
ventricle are moving .
9.( wall motion index) : equals wall-motion-score divided by number
of segments seen. Usually 12-13 segments are seen in an
echocardiogram. Use this variable INSTEAD of the wall motion score.
10. (mult) : a derivate var which can be ignored .
11. (group) : meaningless, ignore it .
12. (alive at one)(class) : Derived from the first two attributes.
(N) means patient was either dead after 1 year or had
been followed for less than 1 year. (Y) means patient
was alive at 1 year.
