Essen Stroke Risk Score (ESRS) Calculator

Essen Stroke Risk Score (ESRS): Explanation and Clinical Context The Essen Stroke Risk Score (ESRS) is a validated clinical tool designed to estimate the risk of recurrent stroke and major vascular events in patients who have experienced an ischemic stroke or transient ischemic attack (TIA). Developed from the CAPRIE and Essen Stroke Studies, it uses easily obtainable clinical variables to predict long-term vascular risk. The ESRS consists of nine parameters: age (65–75 years = 1 point, >75 years = 2 points), hypertension, diabetes mellitus, current smoking, peripheral arterial disease, previous myocardial infarction, prior stroke/TIA before the index event, and male sex (each 1 point).

The total score ranges from 0 to 9, with higher scores indicating greater risk. Patients with a score of less than 3 are considered at low risk for recurrent vascular events, while those with a score of 3 or higher are at high risk and require intensified secondary prevention measures. These include optimal control of blood pressure, glucose, lipid levels, antiplatelet therapy, and lifestyle modification (cessation of smoking, diet, and exercise).

In validation studies, an ESRS >3 was associated with an approximately twofold increase in the risk of recurrent stroke or vascular death within one year. This makes ESRS an efficient bedside and outpatient screening tool for guiding the intensity of secondary prevention strategies.
