Do retinal microvascular signs predict ischaemic heart disease subtype? The Australian Heart Eye Study (AHES)

心脏大血管的狭窄和小血管的功能异常都是冠心病和胸痛的原因，很少有非侵入性检查，以帮助区分大血管和小血管疾病，并评估一个人在未来发展疾病的风险。该研究使用视网膜摄影和冠状动脉造影术来评估是否可以使用眼睛血管结构的变化以确定冠心病的类型以及未来心脏事件的风险。

Narrowing of the large vessels of the heart and abnormal function of the small vessels are both causes of coronary heart disease and chest pain.There are few non-invasive investigations to help differentiate between large and small vessel disease and assess one’s risk of developing disease in the future.The study uses retinal photography and coronary angiography to assess whether changes in the structure of the blood vessels of the eye may be used to identify the type of coronary heart disease as well as the risk of future cardiac events.
