Tip of The Week- Cardiac Related Lab Values
Cardiac enzyme studies measure the level of certain enzymes and proteins in the blood. Normally, the level enzymes looked at in this study are low. In case of injury to the heart muscle, the enzymes and proteins leak out of damaged heart muscle cells, and their levels in the bloodstream rise.
These tests are done to confirm diagnosis of a suspected impending heart attack especially if the patient complains of chest pain, shortness of breath, nausea and abnormal ECG results.
Electrolytes on the other hand not only affect organs related to fluid regulation but also to the heart. Take for instance the Potassium, it affects not only contractility of the skeletal muscles but also the muscles of the heart. Abnormal serum potassium levels can put a patient at risk for arrhythmias.
Professional nurses and nursing students should always keep in mind the importance of these tests especially to patients at increased risk for cardiac arrest or MI and also remember the factors that can affect the test results like medications, recent activity, alcohol use, and other disease processes.
