Key result
Peri-operative silent myocardial ischaemia occurred in 42 of 127 patients and was associated with new postoperative symptoms including fatigue (p < 0.05), whereas cardiac risk factors were not.

Silent ischaemia may flag higher postoperative symptom burden after joint replacement; leaves open whether targeted monitoring improves outcomes.

Does peri-operative silent myocardial ischemia predict postoperative morbidity in patients undergoing lower limb joint replacement surgery?
p-value: p=<0.05
Peri-operative silent myocardial ischemia is associated with increased postoperative symptoms such as fatigue, but its occurrence is not predicted by pre-operative cardiac risk factors.
French et al. (1999) conducted an observational in Major lower limb joint replacement surgery (n=127). Ambulatory ECG monitoring was evaluated on Incidence of silent myocardial ischemia and link to postoperative morbidity (p=<0.05). Peri-operative silent myocardial ischaemia occurred in 42 of 127 patients and was associated with new postoperative symptoms including fatigue (p < 0.05), whereas cardiac risk factors were not.
