Abstract:
Objective To explore the relationship of plasma NT-proBNP and age in elderly patients with severe heart failure with left ventricular ejection fraction (LVEF) preserved. Methods According to LVEF, 450 inpatients with severe heart failure (NYHA III-Ⅳ) were divided into two groups.They were LVEF≥50%(LVEF preserved) group and LVEF<50%(LVEF decreased) group. Clinical data were compared and analysed between the two groups. Linear correlation analysis was applied between Log (NT-proBNP) values of patients and ages. Results LVEF preserved group of elderly patients with severe heart failure were 183 cases. LVEF decreased group of elderly patients with severe heart failure were 267 patients. LVEDD and Log(NT-proBNP) values in LVEF preserved group of elderly patients with severe heart failure were lower than that in LVEF decreased group(P<0.01). Log(NT-proBNP) values of LVEF preserved group of elderly patients with severe heart failure were positively correlated with ages (r=0.207, P<0.01). Conclusion Diagnostic value of plasma NT-proBNP on LVEF preserved patients in elderly with severe heart failure was far inferior to LVEF decreased patients in elderly with severe heart failure. The level of plasma NT-proBNP increased with age.
