Stroke Risk Assessment Tool (SRAT)

The Stroke Risk Assessment Tool (SRAT) was developed by National Stroke Association in collaboration with Dilip Pandey, MD, PhD, University of Illinois, Chicago. The ultimate goal of the tool is to increase stroke awareness (and reduce the number of strokes) by facilitating conversations between healthcare professionals and patients about stroke risk and modifiable stroke risk factors.

SRAT is based on a complex algorithm that considers a range of controllable risk factors associated with stroke and other chronic diseases. It is a clinical tool intended for use by healthcare professionals in conjunction with their own professional training, clinical examination and judgment, and knowledge of a specific patient’s medical history. Use of this tool by non-healthcare professionals is not recommended.

Traditional Stroke Risk Assessment Models

The Framingham Heart Study Stroke-risk Model is considered the medical industry standard for identifying stroke risk. This tool is used to identify the common factors or characteristics that contribute to cardiovascular disease and it is an important milestone in quantitative stroke-risk estimation.

The global vascular risk score (GVRS) that is predictive of stroke, myocardial infarction, or vascular death – and has recently been published from the Northern Manhattan Cohort study database. The GVRS is derived from a multiethnic (Hispanic, Black and Caucasian) population and shows an improvement in the prediction of global vascular risk (stroke and myocardial infarction) by adding behavioral risk factors such as alcohol consumption and physical activity, as well as the anthropometric measure of waist circumference, to the traditional Framingham cardiovascular risk profile.

A New Model is Here

For the past few years, National Stroke Association and Dilip Pandey, MD, PhD, have been engaged in a research collaboration that pooled study populations of the longitudinal studies Atherosclerosis RISK in Communities (ARIC), Cardiovascular Health Study (CHS), and MultiEthnic Study of Atherosclerosis (MESA). Data from the first two studies, ARIC and CHS, was used to generate a calibrated algorithm to predict a first stroke within the next ten-years for the entire patient population. Data from the third study, MESA, was used for further validation of the algorithm.

Patient Tools

Help your patients understand their risks and any possible connection they have to stroke. Using the SRAT with your patients during their office visit, you will be able to illustrate to them their personal stroke risk. No matter which risk factors are identified, empower your patients to learn more and take control by providing them with some fact sheets:

High Blood Pressure and Stroke                                 Smoking and Stroke

Atrial Fibrillation and Stroke                                      Healthy Eating Habits            

Diabetes and Stroke                                                    Physical Activity

Cholesterol and Stroke                                                          

The SRAT tool allows you to reinforce to your patient that their risk of a stroke is directly related to their total number of High and Moderate risk factor. As a healthcare professional, your goal is to work with your patients on strategies to improve those High and Moderate risk factors that can be controlled. This tool can illustrate that lifestyle changes, such as healthy eating and physical activity, or possibly medications, can help your patient reduce their risk for stroke. And it can reinforce that it is never too late to start improving their health!


The Stroke Risk Assessment Tool (“SRAT”) is a clinical tool intended for use by healthcare professionals to be used in conjunction with their own professional training, clinical examination and judgment, and knowledge of a specific patient’s medical history. Use of this tool by non-healthcare professionals is not recommended. The SRAT is not intended to be a substitute for professional medical advice, diagnosis, or treatment. The SRAT is not intended to prevent, diagnose, or treat any medical condition. A qualified healthcare professional should always be consulted with any questions regarding any medical condition or stroke risk factor. Never disregard professional medical advice or delay in seeking it based on the SRAT.

The SRAT was create to conform to the standards of professional practice and to reflect the widely accepted consensus of the medical and research communities regarding stroke risk assessment at the time of its creation. However, standards and practices in medicine change as new data and research become available and any healthcare professional using SRAT should consult a variety of sources in conducting a stroke risk assessment. The SRAT is informational only and should not be treated or relied upon as medical advice and is provided without any representations or warranties, express or implied, regarding the accuracy, completeness, or adequacy of the contents of the information provided, and National Stroke Association expressly disclaims liability for error and omissions in the such information.
