At the age of 19, she was discovered by George Burns in Las Vegas. She appeared on The Jack Benny Show, and was soon in the movies with Pocketful of Miracles. Her first important role came in 1963 with Bye, Bye Birdie, a musical about a rock star who is drafted into the army (hmmm...).
The enzyme level continues to rise for the first 18 to 24 hours after a heart attack and slowly returns to normal after a few days. If creatine kinase is elevated, a more specific test (troponin) can help confirm the presence of a heart attack.
Levels peak within 12 to 24 hours and then return to normal within 2 to 4 days. If additional damage occurs or it is ongoing, such as during a second or subsequent heart attack, then CK levels may stay elevated. Sometimes, the CK test may be ordered when a heart attack is suspected and a troponin test is not available. In this case, when CK is elevated, a CK-MB test may be used as a follow-up test to determine whether the increase is due to heart damage or skeletal muscle damage. Chest pain and increased CK levels plus elevated CK-MB indicate that it is likely that a person has recently had a heart attack.
