Hi, I also was just recently diagnosed with an ASA and as Me967 mentions, I am on a small does of aspirin daily. I have been told to get on with my life as normal, only to avoid high altitudes ( no sky-diving!) and deep sea diving due to the pressure. It is also important to stay well hydrated especially on flights or long car journeys. I'm sure your husband will be fine and perhaps introducing a healthier lifestyle to cut down the cholestorol will be an overall benefit to his health.
Hi. I have an ASA myself and was told to take a low dose aspirin everyday as a preventative for a stroke. I think due to new technology ASA's are showing up more often. His cholesterol should be reduced and this would also help also.
Maybe someone else can answer better than I. Take care
