ABSTRACT
Objective To investigate hemodynamie change in uremia complicating heart failure of elderly patients. Methods Totally 241 cases with uremia complicating heart failure received measurement of circulation dynamic detection(CD).The volume load,myocardial contractility and blood pressure were analyzed in the elderly group aged(71±6)years (n=116) and young and middleaged group aged(38± 10)years(n =125). Results The central venous pressure(CVP)[(26.7±11.3)cmH2O vs.(23.6 ± 10.7) cm H2O,t=2.410,P =0.010],effective circulation volume (ECV)[(4362± 1340)ml vs.(3085 ± 1001 ) ml,t =7.674,P =0.000],stroke volume(SV) [(185 ± 52) ml vs.(114±41)ml,t=7.803,P=0.000],cardiac output (CO)[( 13.9±4.3)L/min vs.(11.2±3.6)L/min,t=4.802,P=0.000],left ventricular end diastolic volume (LVD)[(388± 145)ml vs.(258±98)ml,t =7.673,P =0.000],left ventricular end systolic volume ( LSV ) [( 223 ± 95 ) ml vs.( 135 ± 59) ml,t =7.186,P=0.000] were significantly higher group than in young and middle-aged group.The ejection pressure (EP)[(178±29)mm Hg vs.(183±24)mm Hg,t=2.323,P=0.012],myocardium negative inotropic(MNC) [(0.609±0.149)vs.(0.683±0.188),t=3.113,P=0.002],ejection fraction (EF) [(0.433± 0.034) vs.(0.445 ± 0.031 ),t =2.451,P =0.010],diastolic blood pressure (DBP) [( 87 ±14)mm Hg vs.(1.08±22)mm Hg,t=8.141,P=0.000],systematic vascular resistance(SSR)[(952±207)gcm-4 s-2 vs.(1217± 308) gcm-4 s-2,t =7.143,P=0.000],ejection resistence(ER) [( 178± 29)vs.( 183 ± 24),t =2.323,P =0.012] were lower in elderly group than in young and middle-aged group.DBP(x2 =16.474,P=0.000,OR=0.752,95％CI:0.714-0.790),SBP(x2 =11.913,P=0.000,OR=1.148,95％CI:1.091-1.205),ER(x2 =17.892,P=0.000,OR=0.906,95％CI:0.861-0.951),CVP(x2 =14.672,P=0.000,OR=0.698,95％CI:0.663-0.733) and LDV(x2 =21.080,P=0.000,OR=0.942.95％ CI:0.895-0.989) were dangerous factors of uremia complicating heart failure.Conclnsions The increased volume load,decreased myocardial contractility and cardiac afterload may appear in the elderly patients with uremia complicating heart failure.
ABSTRACT
Objective To investigate the relationship between metabolism syndrome (MS) and fatty liver. Methods Plasma lipids, plasma glucose, liver function, blood pressure, body height and body weight were determined in 666 leaders receiving physical examination. Their livers were also examined by ultrasound. Whit analysis of variance and chi-square test, the effect of plasma lipids, plasma glucose, blood pressure, and weight index on fatty liver, and the relation between MS and fatty liver were analyzed. Results The weight index, systolic pressure, diastolic pressure, and the levels of total cholesterol, triglyceride, apolipoprotein B and plasma glucose in the patients with fatty liver were higher than those in healthy subjects. The levels of high-density lipoprotein and apolipoprotein A were lower in patients with fatty liver than those in healthy subjects. The morbidity of fatty liver in the patients with MS was higher than that in healthy subjects. Conclusion There was a close relation between MS and fatty liver. It was necessary to early treat MS.
