rapid diagnosis of acute myocardial infarction

to improve the specificity of biochemical markers of myocardial infarction (mi) a method to measure cardiac troponin-i (ctn-i) was developed. ctn-i is a protein unique to cardiac muscle and is released after mi. consecutive 150 patients admitted to the coronary care unit was studied. value of ctn-i was determined in all samples. ctn-i concentration in the mi patients group was increased compared to that in the control [18.7 +/- 0.13 (mean +/- sd, n = 100 ) vs. 5.31 +/- 0.13, n = 50] µg/l. measurement of ctn-i accurately detects mi in patients and should facilitate the diagnosis and management of such patients.
