The Impact of Finerenone on Changes in Pulse Wave Velocity, Arterial Pressure and Heart Related Deaths in Hemodialysis Patients—Study Perspective

The description in the abstract lacks clear logic and a comprehensive summary of this study, so please revise and improve it according to the design theme and main content of this study, and describe it in the order of (research background), purpose/aim, method, results and conclusions. The introduction of the abstract and preface is rather lengthy, but the summary of the whole study and the presentation of the research background are not perfect (mainly because the logic of the context is not clear and orderly), so it will appear a bit messy. Hope to be able to modify (this has been mentioned in the preliminary opinion). Cardiovascular events (CVE) pose a significant threat to individuals with end-stage renal disease (ESRD), yet these patients are often excluded from cardiovascular clinical trials, leaving prognostic factors associated with CVE in ESRD patients largely unexplored. Recent human studies have demonstrated elevated circulating aldosterone levels in ESRD patients, correlating with left ventricular hypertrophy. Additionally, animal models have shown improvements in uremic cardiomyopathy with spironolactone therapy, prompting interest in assessing the efficacy of spironolactone or eplerenone in reducing mortality and improving cardiovascular function in dialysis patients. Clinicians have historically been cautious about prescribing mineralocorticoid receptor antagonists (MRAs) to congestive heart failure patients with chronic kidney disease (CKD) due to hyperkalemia risk. However, the emergence of finerenone, a novel MR antagonist with a favorable safety profile and lower hyperkalemia risk, has renewed interest in MRA therapy in this population. Heart disease, including coronary artery disease, hypertension, and left ventricular failure, is alarmingly prevalent in dialysis patients, contributing significantly to elevated mortality rates compared to the general population. Arterial stiffness, as indicated by pulse wave velocity (PWV), progressively worsens with advancing CKD stages, peaking in severity among ESRD patients undergoing dialysis. High PWV serves as a crucial risk stratification tool in ESRD. Elevated NT-proBNP and BNP levels in ESRD patients are well-documented, with significant associations observed between baseline peptide concentrations and cardiovascular morbidity and mortality. By incorporating finerenone into our study, we aim to investigate its potential benefits in reducing arterial stiffness, lowering blood pressure, and ultimately mitigating heart-related mortality among hemodialysis patients. This study holds substantial implications for hypertension and cardiovascular risk management in this vulnerable patient population. Eligible participants must have been on chronic hemodialysis for at least three months, with ACE inhibitors or angiotensin receptor blockers included in their therapy at maximum tolerable doses. Serum potassium levels 5.7 mmol/L, left ventricular ejection fraction 50%, and PWV higher than age-estimated values are also prerequisites for study entry. Randomized allocation will be conducted using a permuted block design, stratified by center, with allocation communicated via signed study forms during initial examinations. All steps of this research will be conducted in accordance with the principles of the Helsinki Declaration.

Lipoprotein(a)and Benefit of PCSK9 Inhibition in Emergency Complex Higher-risk and Indicated Patients

Objective There is a large population of patients classified as complex higher-risk and indicated patients(CHIPs)in China with a poor prognosis.The treatment of these patients is complex and challenging,especially when acute cardiac events occur,such as acute coronary syndrome(ACS)or heart failure.Pharmacotherapy and some mechanical circulatory support(MCS)therapeutic devices can provide stable hemodynamic support for CHIPs-percutaneous coronary intervention(PCI).LDL-C is an important pathogenic factor in atherosclerosis,and the target of blood lipid control.Recent studies have revealed that lipoprotein(a)[Lp(a)],which is formed when a covalent bond between apolipoprotein(a)and apolipoprotein B-100 is made,produces an LDL-like particle.This particle is an independent risk factor for the development of atherosclerosis,and is closely correlated to stent thrombosis and restenosis.Furthermore,this requires active intervention.PCSK9 inhibitors have been used in lipid-lowering treatment,and preventing atherosclerosis.The present study explores the efficacy of PCSK9 inhibitors in CHIPs-ACS,and the association between the change in Lp(a)and survival after 2 years of follow-up.Methods The present real-world,prospective control study enrolled 321 CHIPs-ACS who underwent emergency PCI from August 2019 to November 2020,and these patients were followed up for 2 years.These patients were divided into two groups:PCSK9 group(n=161)given the combined PCSK9 inhibitor(140 mg of evolocumab every 2 weeks)and statins-based therapy,and SOC group(n=160)treated with statin-based lipid-lowering therapy alone.Then,the change in lipid index was measured,and the cardiovascular(CV)event recurrence rate was evaluated after one month and 2 years.Afterwards,the contribution of serum lipid parameters,especially the Lp(a)alteration,in patients with earlier initiation of the PCSK9 inhibitor to the CV outcome was analyzed.Results The LDL-C level was significantly reduced in both groups:52.3%in the PCSK9 group and 32.3%(P<0.001)in the SOC group.It is noteworthy that the Lp(a)level decreased by 13.2%in the PCSK9 group,but increased by 30.3%in the SOC group(P<0.001).Furthermore,the number of CV events was not significantly different between the PCSK9 and SOC groups after the 2-year follow-up period.In the PCSK9 group,the Lp(a)reduction was associated with the baseline Lp(a)levels of the patients(r2=−0.315,P<0.001).Moreover,the decrease in Lp(a)contributed to the decline in CV events in patients who received ACS CHIPs-PCI,and the decrease in Lp(a)level was independent of the LDL-C level reduction.Conclusion The early initiation of PCSK9 inhibitors can significantly reduce the LDL-C and Lp(a)levels in ACS CHIPs-PCI.However,further studies are needed to confirm whether PCSK9 inhibitors can reduce the incidence of CV disease in CHIPs.

Prognostic relevance of normocytic anemia in elderly patients affected by cardiovascular disease

BACKGROUND Anemia associated with cardiovascular diseases(CVD) is a common condition in older persons. Prevalence and prognostic role of anemia were extensively studied in patients with myocardial infarction(MI) or congestive heart failure(CHF) whereas limited data were available on patients with atrial fibrillation(AF). This study was conducted to assess the clinical prevalence and prognostic relevance of anemia in elderly patients affected by AF and other CVDs.METHODS A total of 866 elderly patients(430 men and 436 women, age: 65-98 years, mean age: 85 ± 10 years) were enrolled.Among these patients, 267 patients had acute non-ST-segment elevation MI(NSTEMI), 176 patients had acute CHF, 194 patients had acute AF and 229 patients were aged-matched healthy persons(CTR). All parameters were measured at the hospital admission and cardiovascular mortality was assessed during twenty-four months of follow-up.RESULTS The prevalence of anemia was higher in NSTEMI, CHF and AF patients compared to CTR subjects(50% vs. 15%, P <0.05), with normocytic anemia being the most prevalent type(90%). Adjusted mortality risk was higher in anemic patient versus non-anemic patient in all the groups of patients [NSTEMI: hazard ratio(HR) = 1.81, 95% CI: 1.06-2.13;CHF: HR = 2.49, 95% CI:1.31-4.75;AF: HR = 1.98, 95% CI: 1.01-3.88]. Decreased hemoglobin levels(P = 0.001) and high reticulocyte index(P = 0.023) were associated with higher mortality in CVD patients.CONCLUSIONS The significant associations between CVD and anemia and the prognostic relevance of anemia for elderly patients with CVD were confirmed in this study. The presence of anemia in AF patients is associated with a two-fold increased mortality risk compared with non-anemic AF patients. Low hemoglobin and high reticulocyte count independently predict mortality in elderly patients with CVD.

Argon plasma coagulation for superficial esophageal squamous-cell carcinoma in high-risk patients

AIM: To evaluate the usefulness and safety of argon plasma coagulation (APC) for superficial esophageal squamous-cell carcinoma (SESC) in high-risk patients. METHODS: We studied 17 patients (15 men and 2 women, 21 lesions) with SESC in whom endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and open surgery were contraindicated from March 1999 through February 2009. None of the patients could tolerate prolonged EMR/ESD or open surgery because of severe concomitant disease (e.g., liver cirrhosis, cerebral infarction, or ischemic heart disease) or scar formation after EMR/ESD and chemoradiotherapy. After conventional endoscopy, an iodine stain was sprayed on the esophageal mucosa to determine the lesion margins. The lesion was then ablated by APC. We retrospectively studied the treatment time, number of APC sessions per site, complications, presence or absence of recurrence, and time to recurrence.RESULTS: The median duration of follow-up was 36 mo (range: 6-120 mo). All of the tumors were macroscopically classified as superficial and slightly depressed type (0-Ⅱc). The preoperative depth of invasion was clinical T1a (mucosal cancer) for 19 lesions and clinical T1b (submucosal cancer) for 2. The median treatment time was 15 min (range: 10-36 min). The median number of treatment sessions per site was 2 (range: 1-4). The median hospital stay was 14 d (range: 5-68 d). Among the 17 patients (21 lesions), 2 (9.5%) had recurrence and underwent additional APC with no subsequent evidence of recurrence. There were no treatment-related complications, such as bleeding or perforation. CONCLUSION: APC is considered to be safe and effective for the management of SESC that cannot be resected endoscopically because of underlying disease, as well as for the control of recurrence after EMR and local recurrence after chemoradiotherapy.

Usefulness of the Japanese version of Rapid Dementia Screening Test for mild cognitive impairment in older patients with cardiovascular disease:a cross-sectional study

BACKGROUND Cognitive decline is common among older patients with cardiovascular disease(CVD) and can decrease their self-management abilities. However, the instruments for identifying mild cognitive impairment(MCI) are not always feasible in clinical practice. Therefore, this study evaluated whether MCI could be detected using the Japanese version of the Rapid Dementia Screening Test(RDST-J), which is a simple screening tool for identifying cognitive decline.METHODS This retrospective single-center study included patients who were ≥ 65 years old and hospitalized because of CVD.Patients with a pre-hospitalization diagnosis of dementia were excluded. Each patient's cognitive function had been measured at discharge using the RDST-J and the Japanese version of the Montreal Cognitive Assessment(Mo CA-J), which is a standard tool for MCI screening. The correlation between the two scores was evaluated using Spearman's rank correlation coefficient. Receiver operating characteristic(ROC) analysis was also to evaluate whether the RDST-J could identify MCI, which was defined as a Mo CA-J score of ≤ 25 points.RESULTS The study included 78 patients(mean age: 77.2 ± 8.9 years). The RDST-J and Mo CA-J scores were strongly correlated(r = 0.835, P < 0.001). The ROC analysis revealed that an RDST-J score of ≤ 9 points provided 75.4% sensitivity and 95.2% specificity for identifying MCI, with an area under the curve of 0.899(95% CI: 0.835-0.964). The same cut-off value was identified when excluding patients with a high probability of dementia(RDST-J score of ≤ 4 points).CONCLUSIONS The RDST-J may be a simple and effective tool for identifying MCI in older patients with CVD.

Cardiovascular prevention in elderly patients

In recent decades,life expectancy has been increasing significantly.In this scenario,health interventions are ne-cessary to improve prognosis and quality of life of elderly with cardiovascular risk factors and cardiovascular disease.However,the number of elderly patients included in clinical trials is low,thus current clinical practice guidelines do not include specific re-commendations.This document aims to review prevention recommendations focused in patients≥75 years with high or very high cardiovascular risk,regarding objectives,medical treatment options and also including physical exercise and their inclusion in cardiac rehabilitation programs.Also,we will show why geriatric syndromes such as frailty,dependence,cognitive impair-ment,and nutritional status,as well as comorbidities,ought to be considered in this population regarding their important pro-gnostic impact.

Objective: Given the unique cultural background, way of life, and physical environment of the Tibetan Plateau, this study aims to investigate the effects of health education using problem-based learning (PBL) approaches on the knowledge, attitude, practice, and coping skills of women with high-risk pregnancies in this region. Methods: 76 high-risk pregnancy cases were enrolled at Tibet’s Linzhi People’s Hospital between September 2023 and April 2024. 30 patients admitted between September 2023 and December 2023 were selected as the control group and were performed with regular patient education. 46 patients admitted between January 2024 and April 2024 were selected as the observation group and were performed regular patient education with problem-based learning approaches. Two groups’ performance on their health knowledge, attitude, practice and coping skills before and after interventions were evaluated, and patient satisfaction were measured at the end of the study. Results: There was no statistical significance (P P P Conclusions: Health education with problem-based learning approaches is worth promoting as it can help high-risk pregnant women in plateau areas develop better health knowledge, attitude and practice and healthier coping skills. Also, it can improve patient sanctification.

Hybrid Common Femoral Artery Surgical Revascularization Associated to Endovascular Femoropopliteal Recanalization in High-Risk (ASA 3 - 4) Patients: A Seven-Year Period Institutional Experience

Objective: The present study was conceived to analyze the clinical benefit of hybrid interventions with surgical common femoral artery (CFA) reconstruction coupled to superficial femoral/popliteal endovascular recanalization for severe infrainguinal multilevel occlusive disease in high-risk ASA Class 3 - 4 patients. Material and Methods: From August 2008 until May 2015, a series of 143 hybrid infrainguinal interventions in 124 ASA Class 3 - 4 patients were performed in our department for Rutherford category 2 - 6 ischemic presentations. Patient demographics, specific risk factors, technical characteristics and patency results were retrospectively examined during a mean 36.8 months of follow-up. In a majority of 94 limbs (65%), the endovascular stage of interventions focused on long (>15 cm) femoropopliteal occlusions in parallel to regular CFA surgical revascularization. Two or three runoff tibial trunks were evinced in 84% cases, while one or none permeable vessel was found in 23 (16%) limbs. Results: Inasmuch surgical approach was successful in all cases, the endovascular stage was technically profitable in 134 (93%) cases. The ABI posto-peratively improved (>1.5) in 73% of cases, while clinical presentation gained at least one Rutherford category in 89% limbs. The mean hospital stay was 6.1 days (3 - 12 days) whereas the 30-day mortality rate in this homogeneous “high-risk” group of patients was 3.2%. Global risk factors alike age (>70 years/p = 0.0005), smoking ((p = 0.0170) and female gender (p = 0.0111), together with CTOs length (>15 cm/(p = 0.0470), severe calcifications (p = 0.0001), poor tibial runoff (p = 0.0001), TASC “C” and “D” lesions (p = 0.360 and (p = 0.0394), the stent number ((n = 3) and length (>6 cm) ((p = 0.0039 and (p = 0.0003) and the initial ABI scoring ((p = 0.0051) showed statistical negative influence on primary patency. Conclusion: Hybrid infrainguinal revascularization may afford useful results in selected ASA “high risk” patients, owning low invasiveness, reproducibility and acceptable patency in return to punctual postoperative surveillance.

Advances and controversies in the management of acute cholecystitis in high-risk, critically ill, and unfit-for-surgery patients: the Italian Society of Emergency Surgery and Trauma guidelines

There is an ongoing debate about the therapeutic strategies for acute cholecystitis in high-risk,critically ill patients,and finding the optimal management option is a work in progress.In the recent study“Acute cholecystitis management in high-risk,critically ill,and unfit-for-surgery patients:the Italian Society of Emergency Surgery and Trauma(SICUT)guidelines”,Prof.Coccolini et al.summarize current knowledge on treating acute cholecystitis in high risk,critically ill,and unfit for surgery patients(1).The article encompasses topics such as patient stratification,risk factors,and outcomes of non-operative gallbladder drainage and advances the knowledge of the field by proposing specific management recommendations for these patient groups.

Second-look surgery plus hyperthermic intraperitoneal chemotherapy for patients with colorectal cancer at high risk of peritoneal carcinomatosis:Does it really save lives?

The treatment of peritoneal carcinomatosis (PC) of colorectal origin with cytoreductive surgery(CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) has a 5-year recurrence-free or cure rate of at least 16%, so it is no longer labeled as a fatal disease, and offers prolonged survival for patients with a low peritoneal carcinomatosis index. Metachronous PC of colorectal origin is so predictable that there is a model which has been used to successfully determine the individual risk of each patient. Patients at risk are clearly identified; those with the highest risk have small peritoneal nodules present in the first surgery (70% probability of developing PC), ovarian metastases(60%), perforated tumor onset or intraoperative tumor rupture(50%). Current clinical, biological and imaging techniques still lack sufficient sensitivity to diagnose PC in its initial stages, when CRS plus HIPEC has a greater impact and a higher cure rate. Second-look surgery with HIPEC or prophylactic HIPEC at the time of the first intervention have been proposed as means of preventing and/or anticipating clinical or radiological relapse in at-risk patients. Both techniques have shown a significant decrease in peritoneal relapses and should be considered essential weapons in the management of colorectal cancer.

Hyperuricemia predicted adverse outcomes in very elderly patients with non-valvular atrial fibrillation

Objective Elevated serum uric acid predicts poor outcomes in patients with cardiovascular disease.We aimed to examine associations between hyperuricemia and clinical outcomes among very elderly patients with non-valvular atrial fibrillation(NVAF).Methods Elderly patients(≥80 years)with NVAF admitted to our hospital from January 2009 to December 2015 were retrospectively studied and were followed up until April 2017.

Diabetes onset before or after the age of 65 does it affect the progression of renal and cardiovascular diseases in the elderly patient？

Type 2 diabetes （T2D） is common in the elderly and more than half of the people with diabetes are over 65 years old. Elderly diabetic patients have a higher frequency of hypertension, coronary artery disease and chronic kidney disease than non-diabetic elderly patients and the risk of these complications increases with patient age, duration of the dia- betes and glycated hemoglobin values. Besides the known classical factors of renal disease progression,

Low Cost Equipment and Short Duration Program Are Not Barriers to Good Outcomes of Cardiac Rehabilitation in Senegalese Patients with Coronary Artery Disease

Cardiac rehabilitation is still underused in Africa, despite its cost effectiveness widely demonstrated around the world. Aim: To evaluate the results of a cardiac rehabilitation program in the first Senegalese outpatient center in low resource context. Patients and Method: We carried out a prospective and interventional study. It compared on one hand a group of coronary patients at baseline and after 6 months of our rehabilitation program and on the other hand a control group of patients not enrolled in rehabilitation. Results: We included 70 patients (30 in the rehabilitation group and 40 in the control group). After rehabilitation, the functional capacity improved: 6.99 ± 2.9 Mets at M0 vs 8.8 ± 2.23 Mets at M6, p = 0.0001. Patients of intervention group significantly increased motivation to lifestyle changes and knowledge about their disease. We found better control at 6 months of hypertension (84.50% vs 33.70%, p = 0.003), diabetes (70.00% vs 26.70%, p = 0.0042), LDL cholesterol (33.00% vs 5.00%, p = 0.002) in the group “Rehabilitation”. Prevalence of psychosocial issues like anxiety and depression decreased in intervention group: 50.00% at M0 to 23.33% at M3 (p = 0.021), then 30.00% at M6 (p = 0.18). Return to work and resuming sexual activity were not significantly different. Conclusion: Comprehensive cardiac rehabilitation program, with low cost equipment in a short duration, could have real benefits in the management of coronary artery disease by reducing anxiety and depression, improving treatment compliance, control of cardiovascular risk factors, lifestyle changes and disease knowledge.
