Cardiovascular Risk in Orthotopic Liver Transplantation (CAR-OLT)

Description

Structures the inputs for the CAR-OLT risk score, a tool designed to predict the 1-year risk of major adverse cardiovascular events (MACE) following orthotopic liver transplantation. The score uses 12 pre-transplant characteristics to stratify candidates, helping to identify those who may require further cardiac testing versus those (Low Risk, score <= 23) who may proceed safely.

Usage

car_olt_score(age, sex, race, employment_status, education_level,
              history_hcc, diabetes, heart_failure, atrial_fibrillation,
              pulmonary_hypertension, systemic_hypertension, respiratory_failure)

Arguments

age	Numeric. Recipient age in years.
sex	String. "Male" or "Female".
race	String. Recipient race (e.g., "White", "Black", "Other").
employment_status	String. "Working" or "Not Working".
education_level	String. "College" or "High School or Less".
history_hcc	Numeric (0 or 1). History of Hepatocellular Carcinoma. (1 = Yes).
diabetes	Numeric (0 or 1). History of Diabetes Mellitus. (1 = Yes).
heart_failure	Numeric (0 or 1). History of Heart Failure. (1 = Yes).
atrial_fibrillation	Numeric (0 or 1). History of Atrial Fibrillation. (1 = Yes).
pulmonary_hypertension	Numeric (0 or 1). History of Pulmonary Hypertension. (1 = Yes).
systemic_hypertension	Numeric (0 or 1). History of Systemic Hypertension. (1 = Yes).
respiratory_failure	Numeric (0 or 1). Respiratory failure (on ventilator) at time of transplant. (1 = Yes).

Value

A list containing:

Inputs	The formatted list of patient risk factors.
Risk_Threshold	Interpretation based on the published low-risk cutoff (<= 23).
