Objective:To investigate the correlation between frailty and immune markers in elderly patients diagnosed with heart failure with preserved ejection fraction(HFpEF).Methods:A total of 416 elderly patients with HFpEF, who were hospitalized in the Department of Geriatrics at Henan Provincial People's Hospital from March 2021 to December 2023, were selected as research subjects.The Fried frailty phenotype was employed to assess frailty.Fasting venous blood samples were collected to measure levels of CD4+ T lymphocytes, CD8+ T lymphocytes, the CD4+ /CD8+ ratio, and immunoglobulins A, M, and G. Spearman correlation analysis and multiple linear regression analysis were conducted to evaluate the relationship between frailty scores and immune markers.Results:Spearman correlation analysis revealed a significant association between frailty score and the CD4+ /CD8+ ratio( r=-0.659, P<0.001), immunoglobulin A( r=-0.454, P<0.001), immunoglobulin M( r=-0.522, P<0.001), and immunoglobulin G( r=-0.802, P<0.001).Furthermore, multiple linear regression analysis indicated that, after adjusting for confounding factors, frailty score served as a significant negative predictor of the CD4+ /CD8+ ratio( β=-0.562, P<0.001), immunoglobulin A( β=-0.366, P<0.001), immunoglobulin M( β=-0.445, P<0.001), and immunoglobulin G( β=-0.772, P<0.001).In comparison to the non-frail group, the frail group exhibited significantly lower values for the CD4+ /CD8+ ratio( β=-0.666, P<0.001)and levels of immunoglobulin A( β=-0.514, P<0.001), immunoglobulin M( β=-0.526, P<0.001), and immunoglobulin G( β=-0.814, P<0.001). Conclusions:In hospitalized elderly patients with heart failure with HFpEF, frailty serves as an independent risk factor for the reduction of the CD4+ /CD8+ ratio, as well as levels of immunoglobulin A, immunoglobulin M, and immunoglobulin G. Furthermore, the frailty score demonstrates a significant negative predictive value for these immunological markers.Therefore, it is essential to enhance our understanding of frailty and to prioritize its prevention and treatment, as this may help mitigate immune dysfunction and promote recovery in elderly patients.

Objective:To observe the construction of mobile health management model for elderly patients with coronary heart disease, and to conduct empirical research.Methods:A total of 86 elderly patients with coronary heart disease treated in Henan Provincial People's Hospital from January 2019 to January 2021 were selected.They were randomly divided into 2 groups: the control group receiving routine intervention(n=43), and the observation group receiving mobile health management mode as an add-on to routine interventions(n=43).After 3 months of intervention in control versus observation groups, angina, readmission risk factors were assessed, and status of target criteria for low-density lipoprotein cholesterol(LDL-C), resting heart rate, systolic, and diastolic blood pressure as readmission risk factors were evaluated.Before and 3 months after intervention, the self-care ability of patients was evaluated.Results:Number of angina pectoris attacks was less in observation(0.53±0.18)than in control group(0.64±0.15)( t=3.079, P=0.003).Duration of the angina pectoris was shorter in observation(2.72±0.40)min than in control group(3.06±0.55)min, ( t=3.278, P=0.002).Rate of achieving effectiveness of indicators for the risk factors of readmission was higher in observation group than in control group as following data: LDL-C(90.7% and 72.1%, χ2=4.914, P=0.027), resting heart rate(95.4% and 81.4%, χ2=4.074, P=0.044), systolic blood pressure(86.1% and 60.5%, χ2=7.182, P=0.007)and diastolic blood pressure(88.4% and 67.4%, χ2=5.472, P=0.019).The scores of self responsibility, health knowledge, self-care skills and self-concept were higher in the observation group than in the control group, with a statistical significant difference(all P<0.05). Conclusions:The construction of mobile health management model and its application in elderly patients with coronary heart disease are beneficial to improve the symptoms of angina pectoris, reduce the risk factors of readmission and improve the ability of self-care of patients.

Objective:To explore the influencing factors of drug application deviation in elderly diabetes mellitus patients during hospital-family transition period.Methods:A total of 278 elderly diabetes mellitus patients in Henan Provincial People's Hospital from March 2019 to March 2021 were selected as the study subjects.All patients were followed up by telephone 1 week after discharge.The drug deviation evaluation tool(MDT)was used to evaluate the drug application deviation in patients during the hospital-family transition period.They were divided into drug application deviation group and non-drug application deviation group.Sociodemographic and disease-related data and medication management data were compared between the two groups.Logistic regression analysis was used to analyze the influencing factors of drug application deviation in elderly patients with diabetes mellitus during hospital-family transition period.Results:Of the 278 elderly patients with diabetes, 162(58.27%)had at least one drug application deviation during hospital-family transition period.The family care index was lower in drug application deviation group than non-drug application deviation group( Z=6.578, P<0.001).As compared with non-drug application deviation group, drug application deviation group had the higher number of drugs at discharge, and had lower scores of Morisky Medication Adherence Scale with Eight-Item(MMAS-8), had lower scores of Summary of Diabetes Self Care Activities(SDSCA)and had lower scores of Self-efficacy for Appropriate Medication Use Scale(SEAMS), with statistically significant differences( Z=10.971, 6.077, t=5.947, 14.105, all P<0.001).Binary Logistic regression analysis and forest map showed that the more number of discharge medication was a risk factor for drug application deviation during hospital-family transition period in elderly patients with diabetes mellitus( OR=4.128, P<0.001); family care index, MMAS-8 score, SDSCA score and SEAMS score were its protective factors( OR=0.343, 0.523, 0.922, 0.568, all P<0.05). Conclusions:The incidence of drug application deviation during hospital-family transition period is higher in elderly patients with diabetes mellitus.The possible protective factors are high scores of family care index, MMAS-8, SDSCA and SEAMS, and the risk factor is large number of drugs ordered by discharged doctors.Therefore, targeted intervention measures can be implemented to reduce the occurrence of drug application deviation during hospital-family transition period.

Objective:To investigate the relationship between serum albumin(SA)levels and left atrial thrombosis(LAT)in elderly patients with nonvalvular atrial fibrillation(NVAF), and to evaluate the clinical value of SA in predicting LAT in elderly NVAF patients.Methods:Clinical data of 180 elderly patients with NVAF undergone transesophageal echocardiography(TEE)in our hospital were retrospectively analyzed.According to whether there was thrombosis in the left atrium, patients were divided into the thrombus group(n=42)and the non-thrombus group(n=138). Logistic regression was used to analyze factors related to left atrial appendage thrombosis in NVAF patients.The receiver operating characteristic(ROC)curve was used to evaluate the value of serum albumin levels in predicting LAT formation in elderly NVAF patients.Results:The duration of AF was longer in the thrombus group than in the non-thrombus group(all P<0.05). C-reactive protein(CRP)levels and platelet(PLT)counts were higher, and SA levels and the international normalization ratio(INR)were lower in the thrombus group than in the non-thrombus group(all P<0.05). The left atrial diameter(LAD)was larger in the thrombus group than in the non-thrombus group( P<0.05). Multiple Logistic regression analysis showed that the duration of AF and CRP levels were independent risk factors for LAT( P<0.05), and SA levels and INR were independent protective factors for LAT( P<0.05). ROC curve results showed that the area under the curve(AUC)of SA in predicting LAT was 0.778(95% CI: 0.711-0.837, P<0.001). Conclusions:Low serum albumin levels are closely related to LAT in NVAF patients and can be regarded as a predictor of LAT.Serum albumin levels should be monitored in clinical practice to reduce the incidence of stroke events in patients with AF.

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.

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.

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.

Objective: To investigate the impact of comprehensive geriatric assessment(CGA)on treatment outcomes of chronic heart failure(CHF)complicated with emotional disorders in the elderly. Methods: A total of 216 CHF patients with emotional disorders at Henan Provincial People’s Hospital were recruited from September 2017 to March 2019 and were randomly divided into a CGA group and a control group with 108 cases in each group.The control group was given standard drug treatment and psychological counseling, whereas individualized treatment was given to participants in the CGA group in compliance with CGA guidelines.The clinical effects after intervention for 8 weeks in the two groups were examined, using measures such as Hamilton Depression Rating Scale for Depression(HAMD)-24, Hamilton Anxiety Scale(HAMA)-14, amino-terminal pro-brain natriuretic peptide(NT-proBNP), the 6 minute walk test(6MWT)and left ventricular ejection fraction(LVEF). The changes of cognitive status, nutritional status, fall risk and other indicators in patients were comprehensively assessed and statistically analyzed. Results: Compared with pre-treatment data, 8 weeks of treatment for both the control group and the CGA group resulted in decreased HAMD-24 scores(Control group: 31.78±9.08, 23.69±10.16; CGA group: 32.09±8.98, 15.35±7.91; P<0.05), HAMA-14 scores(Control group: 22.38±7.09, 15.28±6.54; CGA group: 21.99±8.12, 10.48±6.82; P<0.05)and NT-proBNP levels[Control group: (4672±392)ng/L, (3279±282)ng/L; CGA group: (4861±378)ng/L, (2387±215)ng/L; P<0.05], and increased LVEF(%)[Control group(34.5±6.2)%, (39.8±7.5)%; CGA group(35.1±3.9)%, (42.5±6.1)%; P<0.05]and 6MWT scores[Control group(298±79±7.5)m, (358±102)m; CGA group(305±98)m, (402±178)m; P<0.05], with more marked changes in all the measures in the CGA group than in the control group(P<0.05). Conclusions The early application of CGA can improve the condition and prognosis in elderly heart failure patients complicated with emotional disorders.

Objective To evaluate the efficacy and safety of double-dosage Clopidogrel in elderly patients with Clopidogrel resistance after percutaneous coronary intervention(PCI).Methods The randomized control trials design was used in this study.108 senile ACS patients with Clopidogrel resistance(platelet inhibition rate＜ 30 ％) were randomized into control group(Clopidogrel 75 mg/d,n =54)and experimental group(Clopidogrel 150 mg/d,n=54).Blood platelet inhibition rate of ADP,major adverse cardiovascular events and main side effects were observed before and 7 d,30 d,90 d and 180 d after intervention.Results Compared with control group,the experimental group was associated with significantly increased platelet inhibition rate on 7 d (22.4 ± 4.5) ％ vs.(37.6 ± 4.5)％,30 d(22.6±4.3)％ vs.(38.8±4.7)％,90 d(22.7±4.6)％ vs.(38.5±4.5)％,and 180 d (23.7±4.3)％ vs.(38.9±4.6)％ after treatment(all P＜0.05).Furthermore,the incidence of main adverse cardiovascular events was also significantly lower in the experimental group(3.7％ vs.35.1％,x2 =15.133,P＜0.001).Meanwhile,the incidence of bleeding and dyspnea were higher in experimental group,but there was no significant difference between the two groups.Conclusions Compared with general dosage,double-dosage of Clopidogrel offers better curative effect and good safety in elderly ACS patients with Clopidogrel resistance after PCI.
