Description

This function returns a patient's risk score for obstructive coronary artery disease based on the 2015 CONFIRM Risk Score.

Usage

calculate_confirm_2015_ptp(
  age,
  sex,
  have_typical_chest_pain,
  have_diabetes,
  have_hypertension,
  have_family_history,
  is_current_smoker,
  max_na_num_of_rf = 0,
  output = c("text", "percentage")
)

Arguments

age

Input numeric value to indicate the age of the patient.

sex

Input characters (female, male) to indicate the sex of the patient.

  • female

is_current_smoker

Input characters (no, yes) to indicate if the patient is a current smoker.

  • no stands for patient is a current smoker.

  • yes stands for patient is a not current smoker (past or non-smoker).

max_na_num_of_rf

Input integer 0 to 5 to indicate the maximum number of missing risk factors to tolerate before outputting an NA. Default: 0

output

Input text to indicate the how pre-test probability results be expressed Default: c("text", "percentage")

  • text means the PTP will be expressed as a probability in text (0 to > 82.4).

  • percentage means the PTP will be expressed as percentage text (0-100%).

Details

The predictive model is based on CCTA images from 9093 patients from Phase I of the Coronary CT Angiography EvaluatioN For Clinical Outcomes: An InteRnational Multicenter (CONFIRM) registry.

Value

A numeric value representing the patient's risk score for obstructive CAD based on the 2015 CONFIRM Risk Score.
