<prompt> Troponin-T is a marker of -Renal diseasesMuscular dystrophyCirrhosis of liverMyocardial infarction  <response>: MARKERS IN MYOCARDIAL INFARCTIONMyoglobinEarliest marker to riseRises within 1 hourClears in 4-12 hoursPoor specificity.Cardiac-specific troponin T cTnT and troponin I cTnINormally NOT detectable in healthy individuals without MIMost sensitive cardiac biomarkerRise at 2 to 4 hoursThe peak at 48 hoursRemain elevated upto 7-10 daysElevated in microinfarctions NSTEMI, not in unstable angina.Creatine kinase CKCK rises within 4-8 hoursReturns to normal in 48-72 hoursNot specific, also rises in Muscle disease. Trauma. IM injections. DefibrillationCK MB isoenzyme is more cardiac specificCK MB also high in Myocarditis, Cardioversion. Cardiac surgeryThe ratio of CK MB mass: CK activity 2.5 suggestive of a cardiac cause.Lactate dehydrogenase LDHLast marker to rise.LDH-1 is specific to cardiac tissueLDH-lLDH-2 ratio is a good indicator of MI.Aspartate aminotransferase - Rarely used clincially.
