Marburg Heart Score (MHS)

Description

Calculates the Marburg Heart Score to rule out coronary artery disease (CAD) in primary care patients presenting with chest pain. The score stratifies patients into low, intermediate, or high probability of having significant CAD based on five clinical predictors.

Usage

marburg_heart_score(age, sex, history_vascular_disease, patient_suspects_cardiac,
                    pain_worsens_exercise, pain_not_reproducible)

Arguments

age	Numeric. Patient age in years.
sex	String. Patient sex ("Male" or "Female"). (Score adds 1 point if Male >= 55 or Female >= 65).
history_vascular_disease	Numeric (0 or 1). Known atherosclerosis, including Coronary Artery Disease, Cerebrovascular Disease, or Peripheral Arterial Disease. (1 = Yes, +1 point).
patient_suspects_cardiac	Numeric (0 or 1). Does the patient assume the pain is of cardiac origin? (1 = Yes, +1 point).
pain_worsens_exercise	Numeric (0 or 1). Does the pain worsen with exercise? (1 = Yes, +1 point).
pain_not_reproducible	Numeric (0 or 1). Is the pain NOT reproducible by palpation? (1 = Yes/Not Reproducible, +1 point. Note: If pain IS reproducible, enter 0).

Value

A list containing:

MHS_Score	The calculated score (Range 0-5).
Risk_Category	Classification (Low 0-2, Intermediate 3, High 4-5).
CAD_Probability	Estimated probability of significant Coronary Artery Disease.

Examples

# Example 1: High Risk
# 60yo Male (+1), Vascular Hx (+1), Suspects Cardiac (+1), Exertional (+1), Not Reproducible (+1)
# Score = 5
marburg_heart_score(60, "male", 1, 1, 1, 1)

# Example 2: Low Risk
# 40yo Female (0), No Hx, Reproducible pain (Input 0 for 'not reproducible')
# Score = 0
marburg_heart_score(40, "female", 0, 0, 0, 0)
