High blood pressure can harm the vessels supplying blood to the retina. Small vessel changes in the eye — as well as the kidneys — may also signal increased likelihood of abnormal heart rhythm.

People don't have to be medical professionals to help someone having a heart attack. To make a difference, though, non-medical bystanders must be trained in how to take fast emergency action.
