STOP-AF Risk Index Calculator

STOP-AF Risk Index: Explanation and Clinical Context The STOP-AF Risk Index is a proposed clinical risk stratification tool designed to estimate the likelihood of developing atrial fibrillation (AF) in patients without prior AF, based on key clinical and echocardiographic parameters (such as age, prior atrial arrhythmia episodes, left atrial diameter, and presence of sleep apnea). The aim is to identify higher‐risk individuals who may benefit from closer monitoring, early intervention, or targeted preventive strategies. — Definition: A numeric composite score derived from multiple risk factors, with higher values indicating greater AF risk. — Normal/Expected Values: Because this is a newer or illustrative index, formal normative or population‐based cut-offs are not yet widely validated; the categories (low, intermediate, high) are best interpreted in the context of the individual patient and clinical judgement. — Clinical Significance: AF is associated with increased risks of stroke, heart failure, and mortality. Early identification of patients at elevated risk enables proactive measures—such as lifestyle modification (weight loss, sleep apnea treatment), aggressive management of hypertension, and consideration of close rhythm monitoring. — Interpretation Summary: In this index, a lower score suggests relative low risk of developing AF in the near‐term, whereas a higher score suggests the need for vigilance—potentially periodic ECG or Holter monitoring, optimisation of modifiable risk factors, and multidisciplinary coordination.
