Abstract：Objective To study the significance of noninvasive hemodynamic monitoring in elderly recessive heart failure diagnosis.Methods Fifty hospitalized elderly patients were selected.The plasma brain natriuretic peptide precursor(NT-ProBNP) concentration was measured.NT-ProBNP 450 ng/L was regarded as a critical value for typical heart failure group and subclinical heart failure group.The stroke volume(SV),stroke index(SI),cardiac output(CO),cardiac index (CI),acceleration index (ACI),velocity index (VI),thoracic fluid content (TFC),systolic time ratio(STR) were measured.Results Typical heart failure group were significantly lower than the subclinical heart failure group in SV,SI,CO,CI,ACI,VI [(59 ± 6) ml vs (83 ± 5) ml,(32 ± 3) ml/m2 vs (51 ±4)ml/m2,(3.1 ±0.8)L/min vs (5.7 ± 1.2)L/min,(2.0 ±0.5)L/(min · rn2) vs (3.2 ±0.8)L/(min · m2),(58 ± 15) vs (76 ±28),(30 ± 13) vs (45 ± 10)],and the SVRI,SVR,TFC,STR were higher than those in subclinical heart failure group[(3145 ± 1100) dyn/(s · cm5 · m2) vs (2018 ± 298) dyn/(s · cm5 · m2),(1802 ± 654) dyn · s/(cm5 · m2) vs (1234 ± 321) dyn · s/(cm5 · m2),(54 ± 7) kΩ vs (33 ± 6) kΩ,(0.50 ± 0.22) vs (0.31±0.21)],and there were significant differences (all P ＜ 0.05).Conclusion Noninvasive hemodynamic monitoring in elderly recessive heart failure diagnosis has an important value.
