In brief: Similar rise but..
Both start to rise 4 to 6 hrs from the onset of chest pain.
Both tend to peak 18 to 24 hrs. The cpk-mb then returns back to base line over 72hrs and trop-i stays up for 1-2 wks. Trop -i is more specific for mi and less false positives. Its more commonly used due to this.
