Creatine phosphokinase (CK) - Levels rise 4 to 8 hours after an acute MI, peaking at 16 to 30 hours and returning to baseline within 4 days
25-200 U/L
32-150 U/L

CK-MB CK isoenzyme - It begins to increase 6 to 10 hours after an acute MI, peaks in 24 hours, and remains elevated for up to 72 hours.
<>400 IU/L

(LDH) Lactate dehydrogenase - Total LDH will begin to rise 2 to 5 days after an MI; the elevation can last 10 days.
140-280 U/L

LDH-1 and LDH-2 LDH isoenzymes - Compare LDH 1 and LDH 2 levels. Normally, the LDH-1 value will be less than the LDH-2. In the acute MI, however, the LDH 2 remains constant, while LDH 1 rises. When the LDH 1 is higher than LDH 2, the LDH is said to be flipped, which is highly suggestive of an MI. A flipped pattern appears 12-24 hours post MI and persists for 48 hours.
LDH-1 18%-33%
LDH-2 28%-40%

SGOT - will begin to rise in 8-12 hours and peak in 18-30 hours
10-42 U/L

Myoglobin - early and sensitive diagnosis of myocardial infarction in the emergency department This small heme protein becomes abnormal within 1 to 2 hours of necrosis, peaks in 4-8 hours, and drops to normal in about 12 hours.
In the next lesson we will learn about nuclear medicine. Okay.
