The characteristic of studies exclusively related to the geriatric patients.

	Total patients	Objective	Results
Tang et al. [4]	1835	assess the relation between the geriatric syndrome (dementia and frailty) and elevated cTn values, and the use of cTn to stratify mortality risk in DM	–the geriatric syndrome along with chronic diseases could increase cTn values –cTn could be recommended as an objective measure of mortality in the elderly with diabetes
Sedighi et al. [23]	7062	determine the relationship between cTn elevation and individual comorbidities, and estimate the impact of each comorbidity on cTn levels	–elevated cTn levels were significantly associated with RI, CM, COPD, DM, and Anemia
Sedighi et al. [22]	6822	determine the impact of aging on cTn levels in the presence of comorbidities	–increased cTnT levels were associated with the presence of pre-existing comorbidities independently of age –the cumulative effect of comorbidity decreases the impact of aging on cTn
Di Micoli et al. [27]	443	determine the possibility of correlation between the two different troponin T and I, and age	–age appears to be the most important factor related to elevated cTn

cTn (cardiac troponin), DM (diabetes mellitus), RI (renal insufficiency), CM (cardiomyopathy), COPD (chronic obstructive pulmonary disease).
