ABSTRACT
Objective:To evaluate the efficacy and safety of conventional diuretic therapy versus Tolvaptan in elderly chronic heart failure patients combined with mild to moderate renal insufficiency with hyponatremia, in order to provide clinical evidence for the treatment of heart failure in the elderly.Methods:This was a randomized control trial.A total of 88 elderly chronic heart failure patients combined with mild to moderate renal insufficiency with hyponatremia were randomly divided into the control group(n=46)and the experimental group(n=42). Once enrolled both groups stopped taking oral loop diuretics.In addition to routine treatment, the control group was treated with furosemide 40 mg once a day, while the experimental group was treated with Tolvaptan 15 mg once a day.The rate of effectiveness in relieving heart failure, the diuretic effects and improvement in heart and kidney function were monitored, and changes in serum potassium and sodium levels and the incidences of thirst and other adverse events were compared between the two groups.Results:The effectiveness rate on heart failure was higher in the experimental group than in the control group(85.7% or 36/42 vs.65.2% or 30/46, χ2=17.855, P<0.001). After treatment, greater changes in average 24-hour urine volume from baseline(787.4±219.6 ml vs.388.6±179.6 ml, t=322.588, P<0.001), more weight loss(-2.4±2.1 kg vs.-1.7±1.6 kg, t=6.942, P=0.009), smaller changes in N-terminal pro-B-type natriuretic peptide(NT-proBNP)from baseline(-897.6±432.1 ng/L vs.-578.4±476.9 ng/L, t=539.400, P<0.001), greater changes in left ventricular ejection fraction(LVEF)from baseline(6.5±5.6 % vs.1.5±5.7 %, t=3.966, P=0.048), smaller changes in serum creatinine from baseline(-8.6±12.4 μmol/L vs.9.6±11.3 μmol/L, t=87.161, P<0.001), and greater changes in estimated glomerular filtration rate(eGFR)from baseline(1.4±1.8 ml·min -1·1.73m -2vs.-4.1±5.6 ml·min -1·1.73m -2, t=63.856, P<0.001)and in serum sodium from baseline(6.2±2.1 mmol/L vs.1.4±1.9 mmol/L, t=234.065, P<0.001)were observed in the experimental group than in the control group.There was no significant difference in the incidences of thirst, dry mouth and other adverse events between the two groups(16.7% or 7/42 vs.10.9% or 5/46, χ2=0.626, P=0.429). Conclusions:Tolvaptan can effectively improve the clinical symptoms and cardiac function and correct hyponatremia in elderly chronic heart failure patients combined with mild to moderate renal insufficiency, with a good safety profile.
ABSTRACT
Objective:To evaluate the therapeutic effects of Tolvaptan on refractory heart failure in patients aged 75 years and older.Methods:This was a randomized controlled trial.A total of 68 patients with refractory heart failure aged 75 years and older were divided into the control group(n=38)and the experimental group(n=30)by randomly generated numbers.Patients in the control group were given levosimendan and recombinant human brain natriuretic peptide intravenously plus routine treatments such as diuresis and electrolyte correction.In the experimental group, 30 patients were given a single dose of 15 mg Tolvaptan per day in addition to what was received by the control group.The effects on heart failure were compared between the two groups 1 week after treatment.Changes in rehospitalization rate, emergency intervention frequency and mortality rate were recorded after a 3-month follow-up.Results:Clinical symptoms of heart failure were alleviated in both the experimental and control groups after treatment.Improvements in 24-h urine volume, body weight and 6-minute walking distance were more significant in the experimental group than in the control group after treatment[(1 470.5±200.6)ml vs.(972.5±201.7)ml, (-6.4±2.1)kg vs.(-2.8±1.9)kg, (189.3±13.7)m vs.(151.3±12.5)m, P<0.05]. Changes in serum sodium levels and improvement of LVEF were greater and reduction of N-terminal B-type brain natriuretic peptide(NT-proBNP)levels was more significant in the experimental group than in the control group after treatment[(5.2±2.1)μmol/L vs.(-1.1±2.4)μmol/L, (10.1±4.1)% vs.(7.0±4.0)%, (-6 670±1 815.7)ng/L vs.(-5 025.3±1 876.7)ng/L, P<0.05]. There was no significant difference in the incidence of adverse reactions between the two groups( P>0.05). The experimental group had shorter hospital stays, while the rehospitalization rate, emergency intervention times and mortality had no significant difference between the two groups during the follow-up period( P>0.05). Conclusions:Addition of Tolvaptan to treatment can increase urine volume, improve cardiac function, correct hyponatremia and shorten the length of hospitalization in refractory heart failure patients aged 75 years and older with good safety and has no significant impact on renal function.
ABSTRACT
Objective:To investigate the influence of frailty on post-treatment outcomes in elderly heart failure patients with reduced ejection fraction treated with Sacubitril/Valsartan.Methods:The 231 heart failure patients aged 60 years or over with reduced ejection fraction were enrolled from October 2017 to October 2018 in Department of Geriatric Medicine, Henan Provincial People's Hospital.Patients were divided into the frailty group(n=116)and the control group(n=115). Frailty diagnosis was made by five indexes suggested by LP Fried.Both groups were treated with sacubitril/valsartan(49/51 mg)for 1 year.The left ventricular ejection(LVEF), estimated glomerular filtration rate(eGFR), N-terminal pro B-type natriuretic peptide(NT-proBNP)and other clinical and laboratory indexes were detected before and after treatment and compared between the frailty group and the control group.Results:16 subjects in the frailty group and 11 subjects in the control group dropped out of the study.The frailty group versus the control group showed a higher mortality rate of cardiovascular causes(13.0% or 13/100 vs.6.7% or 7/104, χ2=6.437, P=0.027), a higher first re-hospitalization rate(18.0% or 18/100 vs.11.5% or 12/104, χ2=4.458, P=0.043)and a higher all-cause mortality(16.0% or 16/100 vs.8.6% or 9/104, χ2=3.875, P=0.039). In the frailty group, levels of serum NT-proBNP and creatinine were higher and eGFR was lower after treatment than before treatment[(2 253±144) ng/L vs.(2 094±136) ng/L, (137±24) μmol/L vs.(125±23) μmol/L, (49.2±5.9) ml·min -1·1.73 m -2vs.(56.7±6.3) ml·min -1·1.73 m -2, t=3.674, 2.893 and 2.068, P=0.017, 0.026 and 0.029]. In the control group, serum NT-proBNP levels were lower after treatment than before treatment[(1 828±123) ng/L vs.(1 945±128) ng/L, t=1.896, P=0.043], while serum creatinine levels[(120±22) μmol/L vs.(117±19) μmol/L, t=2.099, P=0.650]and eGFR[(59.8±6.5) ml·min -1·1.73 m -2vs.(61.6±6.8) ml·min -1·1.73 m -2, t=2.444, P=0.173]had no significant difference between post-treatment and pre-treatment. Conclusions:Frailty has adverse affects on the mortality, re-hospitalization rate and renal function in elderly heart failure patients with reduced ejection fraction treated with Sacubitril/Valsartan.

ABSTRACT
Objective To investigate the association of CYP2C19 gene polymorphism with the efficacy of clopidogrel in patients with acute coronary syndrome(ACS) after percutaneous coronary intervention(PCI).Methods Thromboelastography was performed on 260 elderly ACS patients 3 days after PCI.Patients with the adenosine diphosphate(ADP)-induced platelet aggregation inhibition rate ＜30％ were assigned to the clopidogrel resistance group(CR group,n=78),and those with the ADP-induced platelet aggregation inhibition rate ＞ 30％ were assigned to the non-clopidogrel resistance group (non-CR group,n =152).Baseline data,clinical data,CYP2C19 genotype and phenotype were compared between the two groups.Results After drug treatment,the ADP-induced platelet aggregation inhibition rate was(16.0 ± 8.1) ％ for the CR group and (54.4 ± 17.3) ％ for the non-CR group.Of all 230 patients,36 (15.6 ％)had the slow metabolic genotype,66 (28.7 ％)had the intermediate metabolic genotype and 128 (55.7 ％) had the fast metabolic genotype.The difference was statistically significant between the intermediate or fast metabolic genotype group and the slow metabolic genotype group (All P＜ 0.05).In the non-CR group,the slow,intermediate and fast metabolic genotype cases were 12 (33.3 ％),46 (69.7 ％) and 94 (73.4 ％),respectively;There were no statistically significant differences between these groups(x2 =0.35,P＞0.05).In the CR group,the slow,intermediate and fast metabolic genotype cases were 24 (66.7 ％),20 (30.3 ％) and 34 (26.6％),respectively;There were statistically significant differences between these groups(x2=9.72,P＜ 0.01).Conclusions The incidence of CR in elderly patients with acute coronary syndrome after PCI is closely related to the CYP2C19 gene polymorphism.
ABSTRACT
Objective To explore the changes and clinical significance of plasma redox status in patients with acute myocardial infarction,angina pectoris and people with normal coronary artery.Methods According to the clinical manifestation,electrocardiograms and the myocardium markers,68 acute myocardial infarction patients (group A) were involved.68 angina pectoris patients (group B) and 68 normal coronary artery people (group C) were also chosen according to the coronary artery radiographs.Peripheral venous blood of 3 groups were collected.Plasma glutathione (reduced form GSH and oxidized form GSSG) and nicotinamide adenine dinucleotide phosphate (reduced form NADPH and oxidized form NADP+) were detected.The GSH/GSSG and NADPH/NADP+ redox potentials were calculated according to Nernst equation.Results Along with the pathological aggravation of coronary artery (from group C to group A),the levels of GSH [(8.39±1.03)μmol/L,(6.54±0.94) μmol/L,(4.49±0.86) μmol/L,respectively] and GSH/GSSG (14.22±2.14,9.76±1.67,5.76±1.18,respectively) were gradually reduced; the levels of GSSG [(0.59±0.03) μmol/L,(0.67±0.04) μmol/L,(0.78 ± 0.05) μmol/L,respectively] and GSH/GSSG redox potential [(-150.43±3.43) mV,(-141.22±3.12) mV,(-135.21±2.31) mV,respectively] were gradually increased (all P＜ 0.05); the changes of NADPH/NADP+ redox status were similar to GSH/GSSG but milder.Conclusions The imbalance of plasma redox status deviating to oxidation has a relationship with atheromatous plaque formation,plaque rupture and plaque thrombosis in the coronary artery.
ABSTRACT
Objective To observe the clinical efficacy of ezetimibe combined with atorvastatin calcium on hyperlipidemia,and to evaluate the role of ezetimibe on lipid management in elderly patients with coronary heart disease (CHD) after coronary intervention.Methods A total of 150 elderly CHD patients with hyperlipidemia to undergo coronary intervention in our hospital were selected.Patients were randomly divided into the control group and the experimental group (n=75,each).Patients in control group were treated with atorvastatin,and in the experimental group with ezetimibe plus atorvastatin.The change of blood lipids levels and the incidence of adverse reactions were compared between the two groups 1 month after the treatment.Results The numbers of patients with normal serum levels of total cholesterol (TC),triglycerides (TG),low density lipoprotein (LDLC) were much more in the experimental group than in the control group after treatment [68 cases (90.7％) vs.50 cases (66.7％),62 cases (82.7％) vs.44 cases (58.7％),56 cases (74.7％) vs.38 cases (50.7％),x2 =12.87,10.42,9.23,respectively,all P＜0.01].There was no significant difference in the incidence of adverse reactions between the two groups [5.3％ (4 case) vs.2.7％ (2 cases),x2 =0.17,P ＞ 0.05].Conclusions Compared with atorvastatin calcium treatment,ezetimibe combined with atorvastatin calcium treatment has a better clinical efficacy on hyperlipidemia with no increase of adverse reactions in elderly CHD patients.
ABSTRACT
Objective To investigate the value of brain natriuretic peptide (BNP) detection in the diagnosis and treatment of heart failure patients with normal ejection fraction.Methods Totally 78 elderly patient were selected in our hospital,with left ventricular ejection fraction (LVEF) ≥45 ％,among which 52 cases of patients were consistent of heart failure criteria (heart failure group),27 cases with normal left ventricular diastolic function as control group.The echocardiographic indices of diastolic function and the change of the concentration of BNP were compared.Results As compared with heart failure group,BNP concentration (108.7 ± 32.2) ng/L vs.(190.3 ± 41.5) ng/L,left ventricular posterior wall thickness (11.3 ± 1.7) mm vs.(13.6 ± 1.4) mm,left ventricular mass index (119.3±10.2)g/m2 vs.(130.7±8.9)g/m2 were elevated in heart failure group (all P＜0.01).Conclusions BNP detection can be used for a diagnosis of heart failure as a simple and easy method.The BNP and ultrasound heart beat graph combination can improve heart failure diagnostic accuracywith normal ejection fraction in elderly patients.
