lindner {USPS} | R Documentation |
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.
data(lindner)
A data frame of 10 variables collected on 996 patients; no NAs.
Mean life years preserved due to survival for at least 6 months following PCI; numeric value of either 11.4 or 0.
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.
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.
Coronary stent deployment; numeric, with 1 meaning YES and 0 meaning NO.
Height in centimeters; numeric integer from 108 to 196.
Female gender; numeric, with 1 meaning YES and 0 meaning NO.
Diabetes mellitus diagnosis; numeric, with 1 meaning YES and 0 meaning NO.
Acute myocardial infarction within the previous 7 days; numeric, with 1 meaning YES and 0 meaning NO.
Left ejection fraction; numeric value from 0 percent to 90 percent.
Number of vessels involved in the patient's initial PCI procedure; numeric integer from 0 to 5.
