American University of Beirut (AUB) HAS2 Cardiovascular Risk Index

Description

Calculates the AUB-HAS2 score to stratify cardiovascular risk. This simple additive risk index was derived and validated to predict major adverse cardiovascular events (death, myocardial infarction, or coronary revascularization) using four easily obtainable clinical variables: Hypertension, Age, Smoking, and Hyperlipidemia (HAS2).

age	Numeric. Patient age in years. (>= 60 years adds +1 point).

Examples

# Example 1: High Risk
# Hypertension (+1), Age 65 (+1), Hyperlipidemia (+2) -> Score 4
aub_has2_cardiovascular_risk(1, 65, 0, 1)

# Example 2: Low Risk
# Smoking only (+1), Age 40, No HTN/Lipids
# Score = 1
aub_has2_cardiovascular_risk(0, 40, 1, 0)
