ABSTRACT
Objective To investigate the relationship between plasma activin A (ACTA),B－type natriuretic peptide(BNP),growth differentiation factor －15 (GDF－15) and interleukin－6 ( IL－6) levels and heart failure. Methods From January 2017 to December 2018,80 patients with acute heart failure admitted to Lishui Central Hospitalwere selected as observation group.According to NYHA cardiac function classification , 23 patients were classified as grade II,30 patients were classified as grade Ⅲand 27 patients were classified as grade Ⅳ.Another 60 healthy people were selected as control group from January 2017 to December 2018.The left ventricular end －diastolic diameter(LVEDD) and left ventricular ejection fraction (LVEF) were measured by Doppler echocardiography ,and the levels of ACTA, BNP, GDF －15 and IL －6 were measured by ELISA.Results The plasma ACTA [(2.43 ± 0.54)ng／mL],BNP[(219.31 ±34.25)ng／L],GDF－15[(854.31 ±46.57)ng／L],IL－6[(183.25 ±39.89)ng／L] in the observation group were significantly higher than those in the control group [(0.32 ±0.10) ng／mL,(16.74 ± 3.89)ng／L,(467.52 ±60.91)ng／L,(40.31 ±6.57) ng／L]( t＝29.859,45.553,42.591,27.455,all P＜0.05). The LVEDD[(65.73 ±5.38) mm] in the observation group was higher than that in the control group [(47.83 ± 4.31)mm],while the LVEF[(39.82 ±3.56)%]was lower than that in the control group [(64.32 ±4.16)%]( t＝21.170,37.475,all P＜0.05).The ACTA [(3.98 ±0.58) ng／mL],BNP[(304.21 ±41.30) ng／L],GDF－15 [(989.83 ±50.38) ng／L],IL－6[(249.81 ±45.61) ng／L] in grad Ⅳ group were lower than those in grade Ⅱgroup[(1.17 ±0.21)ng／mL,(135.42 ±23.98)ng／L,(735.24 ±41.87)ng／L,(120.74 ±33.45)ng／L] and gradeⅢgroup[(2.41 ±0.52)ng／mL,(217.27 ±35.46)ng／L,(861.32 ±53.46) ng／L,(185.42 ±42.31) ng／L] ( F＝8.391,23.154,17.849,14.568,all P＜0.05).The plasma levels of ACTA,BNP,GDF－15 and IL－6 in gradeⅢgroup were lower than those in gradeⅡgroup (t＝10.764,9.517,9.322,6.025,all P＜0.05).The LVEDD[(72.31 ± 5.91) mm] in grade Ⅳ group was higher than that in grade Ⅱ group [(58.98 ±4.64) mm] and grade Ⅲ group [(66.01 ±5.48) mm], and the LVEF [( 29.97 ±3.36)%] was lower than that in grade Ⅱ group [(51.54 ± 3.27)%]and gradeⅢgroup[(40.35 ±3.81)%],the differences were statistically significant (F＝12.415,9.829, all P＜0.05).The LVEDD in grade Ⅲgroup was higher than that in grade Ⅱgroup,and the LVEF was lower than that in gradeⅡgroup,the differences were statistically significant ( t ＝4.176,10.856,all P＜0.05).Conclusion The levels of ACTA,BNP,GDF－15 and IL－6 in plasma are increased in patients with acute heart failure ,and are closely related to the progress of the disease.They can be used as diagnostic and prognostic indicators of acute heart failure.

ABSTRACT
Objective To study the change of mid-regional pro-adrenomedullin(MR-proADM) level in patients with chronic heart failure and its significance.Methods Randomly selected 330 patients with chronic heart failure,including 120 cases of grade Ⅱ and Ⅲ,90 cases of grade Ⅳ,90 cases were selected.,Within 24 h after the entry of the group and 7 d after symptom relieved,serum N-terminal pro-B-type natriuretic peptide(NT-proBNP),MR-proADM,cardiac ultrasound(left ventricular diameter(LVEDD) and left ventricular function(LVEF)) were measured.Ninety physical examination in the same period as healthy control during the same period.The change of MR-proADM level in patients with chronic heart failure and its significance were analyze.Results Compared with the healthy control group,the level of MR-proADM in patients with chronic heart failure(grade Ⅱ:(641.55±106.34) pmol/l;grade Ⅲ:(684.46±101.33) pmol/l;grade Ⅳ:(737.81±479.37) pmol/l) was significantly higher than that in the control group(610.22±60.84) pmol/l),the difference was statistically significant(F=5.33,P=0.001).At the same time,the level of MR-proADM was increased with the aggravation of heart failure,after drug treatment will decline((608.09±100.81),(617.64±94.32),(642.22±163.53) pmol/L).And MR-proADM levels were significantly positively correlated with NT-proBNP levels and NYHA classification in patients with heart failure(r=0.194,P=0.003;r=0.206,P=0.000).Conclusion MR-proADM has important guiding significance in the diagnosis,classification of patients with chronic heart failure.
ABSTRACT
Objective To investigate the correlation between non high density lipoprotein cholesterol (non-HLD-C)and cardi-ac function in patients with coronary heart disease (heart disease cardiac,CHD).Methods 162 patients with CHD were se-lected as the experimental group of CHD,100 cases of healthy physical examination qualified as the normal control group. CHD experimental group was divided into mild impairment group and severe impairment group according to the degree of impairment of the heart function.The mild impairment group include I and II levels of cardiac function classification and the severe impairment group included III and IV levels of cardiac function classification.To measure separately total cholesterol (TC),triglyceride (TG),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),and to calculate the content of non high density lipoprotein cholesterol (non-HDL-C).To compare the differences between CHD ex-perimental group and normal control group,and the correlation between different indexes of blood lipid and the degree of loss of cardiac function.Results The serum levels of non-HDL-C,TG and LDL in the Cardiac function in mild damage group of the CHD experimental group were significantly higher than those in the normal control group,and there were statistically significant differences between the two groups(t=2.438,2.887,5.253,P<0.05).The serum levels of non-HDL-C,TG and LDL in the severe heart function impairment group of the CHD experimental group were significantly higher than those in the normal control group,and there were statistically significant differences between the two groups (t=2.438,2.887,5.253,P<0.05).The serum level of HDL in the cardiac function in mild damage group of the CHD experimental group was significantly lower than that in the normal control group (t=-3.132,P<0.05).The serum level of HDL in the severe heart function impairment group of the CHD experimental group was significantly lower than that in the normal control group (t=-6.028,P<0.05).In the CHD group,only the serum level of TC in the severe impairment group was signifi-cantly different from that in the control group (t=3.278,P<0.05).The serum levels of non-HDL-C,TG,LDL of mild im-pairment of cardiac function in the CHD experimental group were significantly different from the serum levels of the severe impairment group (t=2.051,2.057,2.281,P<0.05).Logistic regression analysed that the OR value of serum non-HDL-C in CHD group was slightly lower than that of LDL,and significantly higher than TC and TG.With the increase of the degree of cardiac function,the value of OR increased significantly.Conclusion Serum non-HDL-C had a positive correlation with severity of CHD.To a certain extent,it can reflect the severity of CHD and is an important reference index for clinical diag-nosis and treatment of CHD.
ABSTRACT
Objective To investigate the relationships between the concentration of serum NT-proBNP,New York Heart Association(NYHA) classification,left ventricular ejection fraction((LVEF),)and the value of serum NT-proBNP in the evaluation of cardiac function and the diagnosis of chronic heart failure.Methods One hundred and two subjects were selected,including 30 healthy controls and 72 patients with heart failure.The concentration of serum NT-proBNP was determined by an automated electrochemiluminescence immunoassayan Roche Elecsys 2010.LVEF was measured by the modified Simpson′s equation with echocardiography.The diagnosis of clinical physician was considered to be the golden standard for heart failure.Results The relationships between the concentration of serum NT-proBNP and NYHA,serum NT-proBNP levels(287.7 pg/ml) was significantly higher in heart failure patients(287.7 pg/ml) than that in healthy controls 287.7 pg/ml vs (46.1 pg/ml),P
