Association between NT-proBNP Level and the Severity of COVID-19 Pneumonia

Table 2

Clinical events across plasma NT-proBNP groups.

Clinical events	All	NT-proBNP <300 pg/ml	NT-proBNP ≥300 pg/ml	value
	(n = 91)	(n = 69)	(n = 23)
HFNC oxygen therapy	2 (2.2)	1 (1.5)	1 (4.3)	0.444
Mechanical ventilation	8 (8.8)	4 (5.9)	4 (17.4)	0.108
ECMO requirement	2 (2.2)	1 (1.5)	1 (4.3)	0.444
All-cause death	2 (2.2)	0 (0)	2 (8.7)	0.062
Composite events	10 (11.0)	5 (7.4)	5 (21.7)	0.115

Note. Data are expressed as counts and percentage. Pearson’s chi-squared or Fisher’s exact test was used to test the difference between NT-proBNP groups, as appropriate. The composite events were the composite of HFNC oxygen therapy, mechanical ventilation, ECMO requirement, or all-cause death. NT-proBNP: N-terminal pro-B-type natriuretic peptide; HFNC: high-flow nasal cannula; ECMO: extracorporeal membrane oxygenation.
