- Abstract:
- Objective To explore the value of the combination of brain natriuretic peptide (BNP) level and pulmonary artery
computed tomography (CT) in evaluating the prognosis of elderly patients with heart failure (HF). Methods A total of 100 HF
patients were enrolled and then divided into survival group (n=54) and death group (n=46) according to their survival status
during 5-year follow-up. The serum BNP levels were detected and compared between two groups. Pulmonary artery CT
examination was also carried out to obtain the right pulmonary artery diameter (RPAD), interventricular septal thickness
(IVST), ascending aorta diameter (AA), descending aorta diameter (PA), left pulmonary artery diameter (LPAD) and main
pulmonary artery diameter (MPAD). Results Compared with those in death group, the serum BNP level, RPAD and LPAD in
survival group were significantly decreased, and IVST was significantly increased, with statistical differences (P<0.05).
Serum BNP level was positively correlated with RPAD and LPAD, while it was negatively correlated with IVST, and the
differences were statistically significant (P<0.05). Compared with single indicator, the combination of BNP level and
pulmonary artery CT for prognosis evaluation had significantly higher sensitivity, specificity, accuracy, positive predictive
value, negative predictive value and area under ROC curve (P<0.05). Conclusion BNP level combined with pulmonary
artery CT has higher specificity, sensitivity and accuracy in evaluating the prognosis of elderly HF patients, with a higher
clinical reference value.
