Several cardiac enzymes can be measured by blood tests to help diagnose a heart attack. These include creatine kinase (CK) and a subtype of this enzyme called CK-MB.

Excessive fluid buildup around the heart, known as pericardial effusion, can be diagnosed on fetal ultrasound. Pericardial effusion can interfere with the heart’s ability to pump blood to the rest of the body, affecting growth and vitality of the fetus.
