heart_transplant

The Stanford University Heart Transplant Study was conducted to determinewhether an experimental heart transplant program increased lifespan. Eachpatient entering the program was designated officially a heart transplantcandidate, meaning that he was gravely ill and would most likely benefitfrom a new heart. Then the actual heart transplant occurs between a fewweeks to several months depending on the availability of a donor. Very fewcandidates during this waiting period show improvement and get\emph{deselected

  • acceptyear - Year of acceptance as a heart transplant candidate.
  • age - Age of the patient at the beginning of the study.
  • survived - Survival status with levels alive and dead.
  • survtime - Number of days patients were alive after the date they were determined to be a candidate for a heart transplant until the termination date of the study
  • prior - Whether or not the patient had prior surgery with levels yes and no.
