Table 1 Comparative characteristics of patients with left ventricular assistant devices with gastrointestinal bleeding vs no gastrointestinal bleeding, n (%)

Factor		No GIB	At least 1 GIB	P value
n		198	97
Age implant, median (IQR)		56.9 (46.9, 67.0)	60.8 (52.7, 69.8)	0.014
Sex (male)		160 (81.2)	82 (84.5)	0.52

	Asian	0 (0.0)	1 (1.0)
	Other	12 (6.1)	5 (5.2)
	Unknown	19 (9.6)	2 (2.1)
Type of LVAD	Heartware	66 (33.3)	27 (27.8)	0.22
	HeartMate 2	114 (57.6)	55 (56.7)
	HeartMate3	18 (9.1)	15 (15.5)
LVAD purpose	Destination (DT)	113 (57.1)	70 (72.2)	0.030
	bridge to transplant (BTT)	80 (40.4)	25 (25.8%)

LVAD exposure (d) (IQR)		348 (103, 947)	895 (520, 1433)	< 0.001

The following statistical tests were utilized: Wilcoxon rank-sum test [age, left ventricular-assist device(LVAD)], and Fisher’s exact test (sex, race, type of LVAD, LVAD purpose). GIB: gastrointestinal bleeding; IQR: Interquartile range; LVAD: Left ventricular-assist device.
