My father died when an undiagnosed aortic aneurism ruptured about a year after he was diagnosed with PMR and started on prednisolone. Now my sister, who doesn't have PMR, has been found to have a very small (so far) aneurism and she has warned me and our other sister that this may be an hereditary condition - she is a doctor. I think I have heard that steroids put one at greater risk of aneurism and I intend to take this up with my GP and request a scan to set my mind at rest. I've now been on varying dosage of pred for four years, and am currently on 8mg, recently reduced from 10. Does anyone have any experience of aneurism related to steroids?
