Mrs Jalingo develops an irreversible injury of Myocardial tissue. After she has that injury in her heart some of the enzymes will spill into the blood within 30 to 60 minutes of the injury. The CK levels will be elevated in four hours to eight hours after myocardial infarction. Myoglobin levels goes up in one to three hours. And will return to normal within twenty four hours. The doctor will order for cardiac enzymes every 6 to 8 hours for 24hours. The doctor orders for CK-MB which is known as creatinine kinase and myoglobin. The increase in the level creatinine kinase in the blood will be an indication that Mrs Jalingo has suffered an irreversible injury to the myocardial chamber. Peak after 18 to 24 hour and remain high for 72hours. As soon as the test is confirmed, patient is transferred to cardiac monitor unit.( MedTelemetry)if patient is not already there to be monitored. If the CK-MB is within normal range then there is no irreversible injury to the myocardial tissue. From my experience the most precise, that the doctors rely on is the SERUM PROTEIN TROPONIN.Once the Troponin level is high. Mrs Jalingo has suffered Myocardial infarction. (6 hours)Six hours after myocardial infarction high Troponin levels can be detected .It peaks in (2days)two days and last for (16days) sixteen days after myocardial infarction. The doctor will ask what is the Troponin level?. Have it ready for when he or she will ask.
