Elderly patients with non-cardiac admissions and elevated high-sensitivity troponin: the prognostic value of renal function

Table 1 Differences between patients who died in-hospital and those who were discharged alive

	Patients who died (n = 47)	Discharged alive (n = 99)	P value
Age (yr), mean ± SD	87.5 ± 5.3	83.4 ± 8.3	0.001

Female	26 (30)	60 (70)
Male	21 (35)	39 (65)
History of CAD, n	12	26	1
Atrial fibrillation/flutter, n	18	46	0.38
Renal function, n (%)
Known history of CKD	24 (52)	22 (48)	0.001
No history of CKD	23 (23)	77 (77)
Creatinine levels, mg/dL	2.10 (1.03)	1.66 (0.95)	0.008
eGFR (mL/min/1.73 m2), mean ± SD	35.32 ± 19.85	47.17 ± 24.22	0.002
