Usefulness of Serum Cardiac Biomarkers for Predicting In-Hospital Cardiac Complications in Acute Hip Fracture: A Prospective Cohort in 20 High Surgical Risk patients with Age over 55 Years

Table 3

Comparison of the serum level of cardiac biomarkers between the patients who had and did not have either cardiac and noncardiac complications, at the time on admission and 24 hours postoperatively.

	Total (n=20)	Cardiac complication		p-value	Non-cardiac complication		p-value
		Yes (n=5)	No (n=15)		Yes (n=7)	No (n=13)
hsTnI, ng/mL
On admission	8.6 (5.2, 22.0)	99.5 ± 112.9	5.5 (5.0, 10.6)	0.006	8.4 (5.5, 154.4)	9.5 (5.0, 20.0)	0.843
Postoperative 24 hr	10.3 (8.2, 23.8)	28.6 (17.0, 461,3)	9.4 (7.9, 12.8)	0.013	9.0 (6.9, 99.0)	10.5 (9.2, 21.4)	0.501
NT-proBNP, pg/mL
On admission	356 (214, 1643)	2299 ± 2629	281 (208, 802)	0.239	311 (132, 456)	781 (231, 1923)	0.362
Postoperative 24 hr	644 (389, 1830)	2266 ± 1677	586 (310, 943)	0.061	586 (516, 1937)	821 (318, 1661)	0.905

hsTnI: high sensitivity troponin I; NT-proBNP: N-terminal fragment of pro-B-type natriuretic peptide.
⌘: normally distributed value presented as mean standard deviation, and abnormally distributed value presented as median (interquartile range).
: significant difference with p < 0.05.
