calculate_esc_2013_ptp: Calculate ESC 2013 PTP for obstructive CAD

Description

This function returns a patient's pre-test Probability (PTP) of obstructive coronary artery disease (CAD) based on the European Society of Cardiology (ESC) 2013 guidelines.

Usage

calculate_esc_2013_ptp(
  age,
  sex,
  chest_pain_type,
  output = c("numeric", "percentage")
)

Value

An integer or percentage representing the patient's PTP for obstructive CAD based on the ESC 2013 guidelines.

Arguments

age

Input integer value to indicate the age of the patient.

sex

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

• female

• male

chest_pain_type

Input characters (typical, atypical, nonanginal) to indicate the chest pain characteristics of the patient.

• typical stands for the patient having typical chest pain.

• atypical stands for the patient having atypical chest pain.

• nonanginal stands for the patient having nonanginal or non-specific chest pain.

output

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

• numeric means the PTP will be expressed as an integer probability (0-100).

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

Details

The predictive model used to create the guidelines are based on the journal A clinical prediction rule for the diagnosis of coronary artery disease: validation, updating, and extension by 2011 Genders et. al.

Examples

# 35 year old female with typical chest pain
calculate_esc_2013_ptp(
    age = 35,
    sex = "female",
    chest_pain_type = "typical",
    output = "percentage"
)

# 65 year old male with nonanginal chest pain
calculate_esc_2013_ptp(
    age = 65,
    sex = "male",
    chest_pain_type = "nonanginal",
    output = "percentage"
)
