Key result
A peri-operative increase in troponin T in hip fracture patients was associated with higher one-year mortality compared to no increase (45% vs 22%, p=0.03).
Why the study?
Does a peri-operative increase in Troponin T predict one-year mortality in elderly patients with hip fracture?
Population
108 patients over 60 years admitted with hip fracture, average age 84 years, 86% female.
Comparison
Peri-operative increase in Troponin T levels vs No increase in Troponin T levels
Design
Cohort
Follow-up
1 year

Elevated troponin T signals higher 1-year mortality risk after hip fracture; leaves open whether routine testing or intervention improves outcomes.

Does a peri-operative increase in Troponin T predict one-year mortality in elderly patients with hip fracture?
Absolute Event Rate: 45% vs 22%
p-value: p=0.03
Peri-operative elevation of Troponin T in elderly hip fracture patients is associated with increased one-year mortality, though routine measurement without acute cardiac symptoms is not recommended.
Spurrier et al. (2011) conducted a cohort in Hip fracture (n=108). Peri-operative increase in troponin T vs. No increase in troponin T was evaluated on One-year mortality (p=0.03). A peri-operative increase in troponin T in hip fracture patients was associated with higher one-year mortality compared to no increase (45% vs 22%, p=0.03).
