Name of attribute	Description
Survival	This variable indicates the number of months the patient survives
Still-alive	A variable which is binary, still-alive is shown by 1 and dead by 0
Age at heart attack	Age of heart attack occurrence (in years)
Pericardial effusion	A variable which is binary. Fluid around the heart is shown by 1 and no fluid by 0
Fractional shortening	A criterion which measures contractility around the heart
Epss	Another criterion which measures contractility (E-point septal separation)
Lvdd	A criterion which measures the size of the heart (left ventricular end-diastolic dimension)
Wall motion score	A criterion which measures the movement of the left ventricle segments
Wall motion index	This criterion depends on number of segments seen that can be used instead of the wall motion score
Mult	An ignorable var which is derivative
Name	Patient’s name
Group	Meaningless
Alive at 1	A variable which is boolean, patient was dead after one year is shown by 0 and patient was alive at one year by 1
