The TPI is intended for use as an aid to clinicians identifying which patients
with AMI are appropriate candidates for thrombolytic therapy. TPI is intended
for adult patients, aged 35-75, diagnosed with symptoms of acute myocardial
infarction.
These programs can be used in real-time and retrospective settings since they
rely on information that is readily available in the emergency department
(ED), or by retrospective review of the patient’s medical record. The emer-
gency physician’s real-time decision making process is aided by having the
predictive instruments incorporated into the electrocardiograph. The predic-
tive scores, once acquired, can then be used along with actual patient outcome
to help improve patient management practices retrospectively.
The predictive instruments provide the physician with tools to:
l Aid diagnosis and triage of some patients with symptoms suggestive
of ACI
l Identify those patients most likely to benefit from thrombolytic ther-
apy
l Facilitate the earliest possible administration of thrombolytic therapy
NOTE For intended use and contraindication information, consult the Predictive
Instrument Physician’s Guide for important information.
Understanding TPI Variables
There are nine predictors of thrombolytic-related benefits and risks which
include six clinical factors and detailed information on three ECG features.
The six clinical factors are:
l Time since ischemic onset
l Patient age
l Patient gender
l Patient Blood Pressure (systolic and diastolic)
l Patient’s history of diabetes
l Patient’s history of hypertension
