Calculate 2020 Winther Basic PTP for obstructive CAD

This function returns a patient's pre-test probability (PTP) of obstructive coronary artery disease based on the 2020 Winther et. al. basic model (Basic_PTP).

Usage

calculate_winther_2020_basic_ptp(age, sex, chest_pain_type)

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

• male

chest_pain_type

Input characters (no chest pain, typical, atypical, nonanginal) to indicate the chest pain characteristics of the patient.

• no chest pain stands for the patient having no chest pain.

• 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.

Value

A numeric value representing the patient's PTP for obstructive CAD based on the 2020 Winther et. al. basic model (Basic_PTP).

Details

The predictive model is based on > 40000 symptomatic patients from 2008 to 2017 from 13 hospitals in Western Denmark. These patients are registered under the Western Denmark Heart Registry.

Examples

# 40 year old Male with typical chest pain
calculate_winther_2020_basic_ptp(
    age = 40,
    sex = "male",
    chest_pain_type = "typical"
)
#> [1] 0.1430237

# 40 year old Male with nonanginal chest pain
calculate_winther_2020_basic_ptp(
    age = 40,
    sex = "male",
    chest_pain_type = "nonanginal"
)
