I need to read an article that has the PMID: 1542842, title "The Cardiac Illness of General Robert E. Lee" it was written by Mainwaring &
I found the reference in PUBMED.GOV, the article was written in 1992.
Unfortunately we do not have the journal that article is in. It is in a specialized medical journal, Surgery, Gynecologly & Obstetrics. Both Creighton University's Health Sciences Library & UNMC's Library have paper copies of the journal and you may be able to photocopy it.
Alternatively you can request an Interlibrary Loan and we could get a copy of the journal article for you. There will be a charge associated with this service.
