Lindner Center data on 996 PCI patients analyzed by Kereiakes et al. (2000)
Description
These data are adapted from the lindner dataset in the USPS package.
The description comes from that package, except for the variable sixMonthSurvive, which
is a recode of lifepres
Data from an observational study of 996 patients receiving an initial
Percutaneous Coronary Intervention (PCI) at Ohio Heart Health, Christ Hospital,
Cincinnati in 1997 and followed for at least 6 months by the staff of the Lindner Center.
The patients thought to be more severely diseased were assigned to treatment with abciximab
(an expensive, high-molecular-weight IIb/IIIa cascade blocker); in fact, only 298 (29.9
percent) of patients received usual-care-alone with their initial PCI.
Usage
data(lindner)
Format
A data frame of 10 variables collected on 996 patients; no NAs.
- lifepres
Mean life years preserved due to survival for at least 6 months following
PCI; numeric value of either 11.4 or 0.
- cardbill
Cardiac related costs incurred within 6 months of patient's initial PCI;
numeric value in 1998 dollars; costs were truncated by death for the 26 patients with
lifepres == 0.
- abcix
Numeric treatment selection indicator; 0 implies usual PCI care alone; 1
implies usual PCI care deliberately augmented by either planned or rescue treatment
with abciximab.
- stent
Coronary stent deployment; numeric, with 1 meaning YES and 0 meaning NO.
- height
Height in centimeters; numeric integer from 108 to 196.
- female
Female gender; numeric, with 1 meaning YES and 0 meaning NO.
- diabetic
Diabetes mellitus diagnosis; numeric, with 1 meaning YES and 0 meaning NO.
- acutemi
Acute myocardial infarction within the previous 7 days; numeric, with 1
meaning YES and 0 meaning NO.
- ejecfrac
Left ejection fraction; numeric value from 0 percent to 90 percent.
- ves1proc
Number of vessels involved in the patient's initial PCI procedure; numeric
integer from 0 to 5.
- sixMonthSurvive
Survival at six months — a recoded version of lifepres.
