Calculate 2021 PRECISE Clinical PTP for obstructive CAD

Description

This function returns a patient's pre-test probability (PTP) of obstructive coronary artery disease based on the 2021 Predictive Risk scorE for CAD In Southeast Asians with chEst pain (PRECISE) clinical model.

)

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.

have_neck_radiation

Input characters (no, yes) to indicate if the patient has chest pain radiating to the neck.

  • no stands for not chest pain radiating to the neck.

  • yes stands for having chest pain radiating to the neck.

have_diabetes

Input characters (no, yes) to indicate if the patient has diabetes.

  • no stands for not having diabetes.

  • yes stands for having diabetes.

have_hypertension

Input characters (no, yes) to indicate if the patient has hypertension.

  • no stands for not having hypertension.

  • yes stands for having hypertension.

smoking_history_type

Input characters (current, past, none) to indicate the smoking history of the patient.

  • current stands for being a current smoker.

  • past stands for being a past smoker.

  • none stands for not having a smoking history (non-smoker).

have_q_waves

Input characters (no, yes) to indicate if the patient has Q waves on electrocardiogram (ECG).

  • no stands for the patient not having Q waves on ECG.

  • yes stands for the patient having Q waves on ECG.

have_st_t_changes

Input characters (no, yes) to indicate if the patient has ST-T changes on electrocardiogram (ECG).

  • no stands for the patient not having ST-T changes on ECG.

  • yes stands for the patient having ST-T changes on ECG.

Details

The predictive model is based on patients a mixed Asian cohort within Singapore with stable chest pain.

Value

A numeric value representing the patient's PTP for obstructive CAD based on the 2021 Predictive Risk scorE for CAD In Southeast Asians with chEst pain (PRECISE) clinical model.

Examples

# 40 year old female with typical chest pain
# radiating to the neck, has diabetes
# but no hypertension and a non-smoker.
# She has Q waves but no ST-T changes on ECG.
