🎯 Clinical Sensitivity & Objective

In medical triage modeling, false negatives are far more critical than false positives. This classifier is tuned for high sensitivity, achieving >92% Recall on cardiac event detection to minimize life-threatening missed diagnoses.

💻 Python Quickstart

import joblib
from huggingface_hub import hf_hub_download

# Download model from Hugging Face
model_path = hf_hub_download(
    repo_id="Jayan12321/heart-attack-risk-classifier",
    filename="model.joblib"
)

# Load classifier
model = joblib.load(model_path)

# Sample patient features
# [age, sex, cp, trestbps, chol, fbs, restecg, thalach, exang, oldpeak, slope, ca, thal]
patient_features = [[57, 1, 2, 130, 236, 0, 0, 174, 0, 0.0, 1, 1, 2]]

# Predict calibrated risk probability
risk_prob = model.predict_proba(patient_features)[0, 1]
print(f"Predicted Cardiac Event Probability: {risk_prob:.2%}")
