psychopdaROC Cardiac Data - Myocardial Infarction Biomarkers — psychopdaROC

Cardiac biomarker dataset with 180 patients for ROC analysis of MI diagnosis. Features three key cardiac markers: troponin, creatinine, and BNP with realistic clinical distributions.

Usage

psychopdaROC_cardiac

Format

A data frame with 180 rows and 5 variables:

patient_id: Character: Patient identifier (PT001-PT180)
mi_status: Factor: "MI" or "No_MI" (25%/75% prevalence)
troponin: Numeric: Troponin level (ng/mL), mean: 2.5 for MI, 0.3 for No_MI
creatinine: Numeric: Creatinine level (mg/dL), mean: 1.3 for MI, 0.9 for No_MI
bnp: Numeric: BNP level (pg/mL), mean: 850 for MI, 200 for No_MI

Details

Realistic cardiac biomarker distributions for evaluating diagnostic performance in acute MI. Troponin shows strong discrimination, while creatinine and BNP provide complementary diagnostic information.

Examples

data(psychopdaROC_cardiac)
psychopdaROC(data = psychopdaROC_cardiac,
             dependentVars = c("troponin", "creatinine", "bnp"),
             classVar = "mi_status", positiveClass = "MI",
             method = "maximize_metric", metric = "youden")
