摘要
目的探讨无创血流动力学监测对老年隐性心力衰竭的诊断意义。方法选择住院老年患者50例,测量其血浆脑钠肽前体(NT-ProBNP)浓度,以NT.ProBNP450ng/L作为典型心力衰竭组与隐性心力衰竭组的临界值。采用无创血流动力学监测系统测量2组患者每搏输出量(SV)、每搏指数(SI)、每分输出量(CO)、心脏指数(cI)、加速指数(ACI)、速度指数(VI)、胸腔体液水平(TFC).收缩时间比(STR)等并加以比较。结果典型心力衰竭组SV、SI、CO、CI、ACI、VI值明显低于隐性心力衰竭组[(59±6)ml比(83±5)ml,(32±3)ml/m^2比(51±4)ml/m^2,(3.1±0.8)L/min比(5.7±1.2)L/min,(2.0±0.5)L/(min·m^2)比(3.2±0.8)t/(min·m^2),(58±15)比(76±28),(30±13)tL(45±10)],SVRI、SVR、TFC、STR明显高于隐性心力衰竭组[(3145±1100)dyn/(s·cm^2·1/1。)比(2018±298)dyn/(s·cm^2·m^2),(1802±654)dyn·s/(cm^2·m^2)比(1234±321)dyn·s/(cm^2·m^2),(54±7)kΩ比(33±6)k1),(0.50±0.22)比(0.31±0.21)],差异均有统计学意义(均P〈0.05)。结论无创血流动力学监测对评价老年隐性心力衰竭具有重要价值。
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/rain vs (5.7 ±1.2)L/min, (2.0 ±0.5)L/(min·m^2) vs (3.2 ±0.8)L/(min·m^2), (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·cm^2·m^2 ) vs (2018 ± 298) dyn/( s·cm^5·m^2 ), ( 1802 ± 654)dyn · s/(cm5 · m^2) vs (1234±321)dyn · s/(cm^5·m^2), (54 ±7)k· vs (33 ±6)kO, (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.
