Figure 1.
Changes in cardiac structure and the ejection fraction before and after treatment. Compared with the standard treatment group, the rhBNP group exhibited a significant difference (P < .05).
The sequential treatment group exhibited significant differences compared with the standard treatment group (P < .05).
The sequential treatment group presented significant differences compared with the rhBNP group (P < .05). LAD = left atrial diameters, LVEDV = left ventricular end-diastolic volume, LVEF = left ventricular ejection fraction, rhBNP = recombinant human brain natriuretic peptide.
