Are there blood tests that can help my physician to determine how I am doing?

Yes. During a heart attack, some heart muscle cells that lack sufficient blood and oxygen become damaged, releasing various enzymes into the bloodstream. A blood sample may be drawn every few hours to look for these enzymes as one way to diagnose whether a heart attack has occurred and how much muscle has been damaged.

After a heart attack, your physician will always take blood samples to measure blood cholesterol and fractions of blood cholesterol. These tests can reveal your level of risk of developing a future heart attack. These fractions include measures of highdensity lipoprotein cholesterol (HDL), often called the “good” cholesterol, and low-density lipoprotein cholesterol (LDL), often called the “bad” cholesterol. Levels of triglycerides (a type of fat in the blood) are often measured at the same time.
