AI-enabled imaging of retina's vascular network can predict cardiovasculardisease and death
, and previous heart attack. Overall, these predictive models, based on age, smoking, medical history and retinal vasculature, captured between half and two thirds of circulatory disease deaths in those most at risk.
Adding retinal vasculature to Framingham Risk Scores effected only marginal changes in the prediction of stroke or heart attack. But a simpler non-invasive risk score based on age, sex, smoking, medical history and retinal vasculature performed as well as the Framingham Risk Scores, and without the need for blood tests or blood pressure measurement, say the researchers.
They continue,"[Retinal vasculature] is a microvascular marker, hence offers better prediction for circulatory mortality and stroke compared with [heart attack] which is more macrovascular, except perhaps in women. In the UK, for example, it could be included in the primary care NHS Health Check for those aged 41-74, they suggest.
