This function returns a patient's pre-test Probability (PTP) of obstructive coronary artery disease (CAD) based on the American College of Cardiology Foundation, American Heart Association, American College of Physicians, American Association for Thoracic Surgery, Preventive Cardiovascular Nurses Association, Society for Cardiovascular Angiography and Interventions, and Society of Thoracic Surgeons 2012 guidelines.

Usage

calculate_aha_2012_tbl_9_ptp(
  age,
  sex,
  chest_pain_type,
  output = c("numeric", "percentage"),
  label_sex_male = c("male"),
  label_sex_female = c("female"),
  label_sex_unknown = c(NA, NaN),
  label_cpt_nonanginal = c("nonanginal"),
  label_cpt_atypical = c("atypical"),
  label_cpt_typical = c("typical"),
  label_cpt_unknown = c(NA, NaN)
)

Arguments

age

Input integer value to indicate the age of the patient in years.

sex

The value of variable in the parameters label_sex_male, label_sex_female and label_sex_unknown.

chest_pain_type

The value of variable in the parameters, label_cpt_nonanginal, label_cpt_atypical, label_cpt_typical and label_cpt_unknown.

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%).

label_sex_male

Label(s) for definition(s) of male sex. Default: c("male")

label_sex_female

Label(s) for definition(s) of female sex. Default: c("female")

label_sex_unknown

Label(s) for definition(s) of missing sex. Default: c(NA, NaN)

label_cpt_nonanginal

Label(s) for patient having nonanginal or non-specific chest pain. Default: c("nonanginal")

label_cpt_atypical

Label(s) for patient having atypical chest pain. Default: c("atypical")

label_cpt_typical

Label(s) for patient having typical chest pain. Default: c("typical")

label_cpt_unknown

Label(s) for patient having unknown chest pain type symptoms. Default: c(NA, NaN)

Value

An integer or percentage representing the patient's PTP for obstructive CAD based on the ACCF/AHA/ACP/AATS/PCNA/SCAI/STS 2012 guidelines.

Details

The predictive model used to create the guidelines are based on patients from the Diamond and Forrester and the Coronary Artery Surgery Study.

Examples

# 35 year old female with typical chest pain
calculate_aha_2012_tbl_9_ptp(
    age = 35,
    sex = "female",
    chest_pain_type = "typical",
    output = "percentage"
)
#> [1] "26%"

# 65 year old male with nonanginal chest pain
calculate_aha_2012_tbl_9_ptp(
    age = 65,
    sex = "male",
    chest_pain_type = "nonanginal",
    output = "percentage"
)
#> [1] "27%"
