NYHA score and BNP levels in patients on admission and after treatment.

	NYHA score		BNP (pg/mL)		EF (%)
	On admission	After treatment	On admission	After treatment	On admission	After treatment
Responders (n = 22)	3.4 ± 0.2	3.0 ± 0.2	614.3 ± 82.3	184.2 ± 32.0*	17.1 ± 1.3	24.3 ± 3.4
Non-responders (n = 6)	3.2 ± 0.4	3.7 ± 0.3	491.4 ± 73.6	721.1 ± 79.9†	16.6 ± 3.9	19.3 ± 2.9

The New York Heart Association functional classification (NYHA) score, serum levels of brain natriuretic peptide (BNP) and left ventricular ejection fraction (EF) were determined in patients on admission and after treatment. The data after treatment were obtained 82.0 ± 13.7 and 43.2 ± 11.1 days after admission in responders and non-responders, respectively (P = 0.173). Data are expressed as mean ± sem. *P < 0.0001 compared to values on admission. ^†P = 0.0003 compared to values of the responders. Repeated two-way ANOVA followed by Bonferroni’s post hoc test was used.
