label_have_typical_chest_pain_no

Label(s) for patient not having typical chest pain symptom. Default: c("no")

label_have_typical_chest_pain_yes

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

label_have_typical_chest_pain_unknown

Label(s) for patient having unknown typical chest pain symptom.

label_have_diabetes_no

Label(s) for patient with no diabetes. Default: c("no")

label_have_diabetes_yes

Label(s) for patient having diabetes. Default: c("yes")

label_have_diabetes_unknown

Label(s) for patient having unknown diabetes. Default: c(NA, NaN)

label_have_hypertension_no

Label(s) for patient with no hypertension. Default: c("no")

Label(s) for patient having unknown hypertension. Default: c(NA, NaN)

label_have_family_history_no

Label(s) for patient with no family history of CAD. Default: c("no")

label_have_family_history_yes

Label(s) for patient having family history of CAD. Default: c("yes")

label_have_family_history_unknown

Label(s) for patient having unknown family history of CAD. Default: c(NA, NaN)

label_is_current_smoker_no

Label(s) for patients who are not current smokers. Default: c("no")

label_is_current_smoker_yes

Label(s) for patients who are current smokers. Default: c("yes")

label_is_current_smoker_unknown

Label(s) for patient with unknown smoking status.

Value

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

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.
