Answer:

Cardiac troponins ( I and T) remain elevated upto 2 weeks.

Step-by-step explanation:

Troponins are the structural protiens which are released in the blood stream in cradiac ischemic conditions within 4 to 6 hours of an attack of myocardial infarction . Normally they act to regulate muscle contraction. Creatine kinase is also an important biomarker of myocardial infarction but they are not elevated for 2 weeks. Troponins are better biomarkers because of their specificity. These troponins are usually measured in the blood to differentiate between unstable angina and myocardial infarction in people presenting with pain in chest and acute coronary syndrome.
