A prospective study of the impact of serial troponin measurements on the diagnosis of myocardial infarction and hospital and six-month mortality in patients admitted to ICU with non-cardiac diagnoses

Table 2 Summary of troponin T levels in all patients over the whole study period

		Troponin T levels (ng/L)
Group	N	Mean (SD)*	Median*	Minimum of all observations across all days	Maximum of all observations across all days
Definite MI	20	214 (306)	73	9	3,093
Possible MI	39	229 (416)	63	5	3,335
Elevated troponin T only	62	97 (138)	55	0	1,337
Normal	23	3.3 (3.5)	2.4	0	14
ALL	144	133 (271)	45	0	3,335

MI, myocardial infarction; SD, standard deviation.
*Mean and median are of the patients’ mean troponin levels across follow-up period in each group. (Note that this summary of data serves to illustrate the patients’ average troponin levels across follow-up period and are not used in the analyses of patient outcomes).
