While these medications are typically prescribed to treat other heart disease types, such as cardiomyopathy, a person with coronary heart disease may take these medications. By pumping harder, the heart can get more blood out in a single beat.
Based on the non-fiction book originally titled Under the Sabers: The Unwritten Code of Army Wives, by Tanya Biank, the series is set at fictional Fort Marshall, at the old Charleston Naval Base, in North Charleston, South Carolina, home to the also fictional 23rd Airborne Division, a component unit of the XVII Airborne Corps.
In Season 7 Fort Marshall was merged with an Air Force base, mirroring the mergers of several Army posts with nearby Air Force bases as a result of the 2005 Base Realignment and Closure Commission. Mercer Army Medical Center is the fictional hospital on post where some of the characters worked.
