Retinal fluorescein angiography: A sensitive and specific tool to predict coronary slow flow.

Background: Obstructive coronary artery disease (OCAD) and coronary slow flow (CSF) are frequent angiographic findings for patients that have chest pain and require frequent hospital admission. The retina provides a window for detecting changes in microvasculature relating to the development of cardiovascular diseases such as arterial hypertension or coronary heart disease.

Objectives: To assess the coronary and ocular circulations in patients with CSF and those with obstructive coronary artery disease.
