Ο Α.
OB.
OC.
O D.
Changes over time in blood levels of heart enzymes indicate heart muscle health.
When heart cells die, their enzymes indicate a heart attack has occurred.
Living heart cells slough off high quantities of enzymes into the bloodstream.
Before a heart attack, heart enzyme levels are higher in the bloodstream than in the heart muscle tissue.

Answer 1

Physicians monitor a patient's enzyme levels to assess heart muscle health and detect if a heart attack has occurred. Changes in blood levels of heart enzymes over time can indicate heart muscle health or damage. Enzymes released by dying heart cells can indicate a heart attack.

Step-by-step explanation:

Physicians monitor a patient's enzyme levels if they suspect a heart attack because changes over time in blood levels of heart enzymes indicate heart muscle health. When heart cells die, their enzymes indicate a heart attack has occurred. Living heart cells slough off high quantities of enzymes into the bloodstream. Additionally, before a heart attack, heart enzyme levels are higher in the bloodstream than in the heart muscle tissue.
