Test Description

Cardiac troponins are a marker of all heart muscle damage, not just myocardial infarction, which is the most severe form of heart disorder. They are measured in the blood to differentiate between unstable angina and myocardial infarction (heart attack) in people with chest pain or acute coronary syndrome.

When should this test be ordered?
A troponin test is usually be ordered when a person with a suspected heart attack first comes into the emergency room or a heart attack may be suspected and testing done when a person has signs and symptoms of it.
High Risk · >= 10.001 (pg/mL)
hs Cardiac Troponin: Addressing the causes of damage or stress to the heart, regular physical activity, maintaining a heart healthy weight and diet, improving sleep quality, drinking more water and quitting smoking may improve functional cardiac test results. Consult with your doctor for certain medications. Consider nitrates, Calcium channel blockers, beta blockers, ACE inhibitors, angiotensin receptor blockers (ARBs), aspirin, and lipid-lowering agents.
Borderline Risk · 5.401-10 (pg/mL)
