TIMI: TIMI risk scores for nSTEMI, STEMI and ACS

In CCVR/inteRn: What the package does (short line)

Description

Estimates mortality for patients with unstable angina, non-ST elevation MI, ST elevation MI or acute coronary syndrome

Usage

TIMI(
  age = 65,
  Number.of.CAD.risk.factors = 4, 
  known.CAD = "yes",
  aspirin.in.last.7.days = "yes",
  number.of.angina.episodes.in.24.hours = 2,
  ekg.st.changes.over.0.5 = "yes", 
  positive.cardiac.markers = "yes", 
  HR = 100, 
  sbp = 120, 
  which.timi = "nSTEMI", 
  DHA = TRUE, 
  JVD = TRUE, 
  Pulmonary.Edema = TRUE, 
  weight.kg = 67, 
  Anterior.STE = TRUE,
  LBBB = TRUE, 
  time.to.treat = 4
)

Arguments

age	Numerical value corresponding to the age of the patient in years.
Number.of.CAD.risk.factors	Integer value corresponding to the number of risk factors for coronary artery disease.
known.CAD	String value. 'yes' if the patient is known to have coronary artery disease, 'no' otherwise. Use lower case.
aspirin.in.last.7.days	String value. 'yes' if the patient is known to have aspirin in the last 7 days, 'no' otherwise. Use lower case.
number.of.angina.episodes.in.24.hours	Integer value corresponding to the number of episodes of angina in the last 24 hours.
ekg.st.changes.over.0.5	String value. 'yes' if the patient had ST segment changes with an amplitude larger than 0.5 'no' otherwise. Use lower case.
positive.cardiac.markers	String value. 'yes' if the patient had positive cardiac markers (troponins) 'no' otherwise. Use lower case.
HR	Integer value corresponding to the patient's heart rate (beats per minute).
sbp	Integer value corresponding to the patient's systolic blood pressure.
which.timi	String value corresponding to the TIMI score you want to calculate. It can be 'nSTEMI' for unstable angina or non-ST segment elevation MI, 'STEMI' for ST segment elevation MI or 'ACS' for acute coronary syndrome.
DHA	Boolean value. TRUE if the patient has diabetes or hypertension or angina.
JVD	Boolean value. TRUE if the patient has jugular venous distension.
Pulmonary.Edema	Boolean value. TRUE if the patient has pulmonary edema.
weight.kg	Numerical value corresponding to the patient's weight in kg.
Anterior.STE	Boolean value. TRUE if the patient has ST elevation of the anterior leads in the EKG.
LBBB	Boolean value. TRUE if the patient has a new onset Left Bundle Branch Block in the EKG.
time.to.treat	Numerical value corresponding to time from the MI episode began to time of initiating treatment.

Value

Returns a list with the TIMI score calculated for this patient and a short string with a small interpretation of the score when possible.
