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.
Creatine kinase (CK) is an enzyme found in the heart, brain, skeletal muscle, and other tissues. Increased amounts of CK are released into the blood when there is muscle damage. This test measures the amount of creatine kinase in the blood. The small amount of CK that is normally in the blood comes primarily from skeletal muscles. Any condition that causes muscle damage and/or interferes with muscle energy production or use can cause an increase in CK.
