This study aimed to examine the clinical effectiveness of nicorandil and nitrate in addition to optimal treatment for CHD patients. Methods: This retrospective cohort study included patients with CHD between October 2009 and March 2020 from 2 tertiary hospitals in Wuhan, China. Patients were grouped into nicorandil and nitrate groups depending on the first recorded antianginal therapy. Demographic and clinical data were collected from databases of the 2 hospitals. The primary outcome was cumulative 18-month major adverse cardiovascular event (MACE)-free survival, which was evaluated by Kaplan-Meier analysis. Propensity score matching (PSM) and multivariate Cox regression were adopted to adjust for confounding factors. Results: A total of 14,275 patients were analyzed, including 590 and 13,685 patients in the nicorandil and nitrate groups, respectively. With a median follow-up of 0.88 (Q1, Q3: 0.21, 1.54) years, the cumulative 18-month MACE-free survival rates were comparable between the 2 groups (80.0% vs. 75.0%, adjusted hazard ratio (aHR): 1.04, 95% confidence interval (CI): 0.42–2.56, P = 0.982,7) after 1:4 PSM. The cumulative 18-month stroke-free survival rate was significantly higher in the nicorandil group compared to the nitrate group (93.0% vs. 84.0%, aHR: 0.56, 95% CI: 0.34–0.92, P = 0.023,5). Conclusion: This retrospective study showed that nicorandil and nitrate have similar 18-month rates of MACEs in CHD patients, but nicorandil is associated with lower incidence of stroke compared to nitrate. More studies need to be conducted to validate this association and explore the long-term benefit of nicorandil use on the occurrence of MACEs in the future.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"3 1","pages":"152 - 158"},"PeriodicalIF":0.0,"publicationDate":"2023-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44240256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Echocardiography can be used to assess cardiac function and volume status. However, whether echocardiography can reduce the rehospitalization rate remains unclear. This study aimed to evaluate the impact of transthoracic echocardiography (TTE) use on readmission rates in hospitalized patients with heart failure. Methods: The study was based on the Zigong heart failure database, which contained information on 2,008 adult patients with heart failure admitted to the Zigong Fourth People’s Hospital (Sichuan Province, China) from December 2016 to June 2019. Patients were divided into 2 groups according to the usage of TTE on the day of hospital admission (TTE group (1,371 patients) and no TTE group (637 patients), respectively). The primary outcome was the 6-month readmission rate. The statistical approaches used included multivariate Cox regression, propensity score analysis, and an inverse probability weighting model to ensure the robustness of the findings. Results: A significant reduction in 6-month readmission rate was observed among the TTE group compared with the no TTE group (hazard ratio = 0.60, 95% confidence interval (CI) = 0.52–0.69, P < 0.001). The frequencies of intravenous nitrates, diuretics, and inotropes during hospitalization were significantly higher in the TTE group compared with those in the no TTE group (10.9% vs. 8.3%, 88.5% vs. 86.2%, and 66.9% vs. 65.6%, respectively, all P < 0.001). The proportion of patients returning to the emergency department within 6 months was significantly lower in the TTE group compared with the no TTE group (35.6% vs. 50.3%, P < 0.001). Conclusions: Utilization of TEE on admission day was associated with a reduced 6-month readmission rate in hospitalized patients with heart failure.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"3 1","pages":"145 - 151"},"PeriodicalIF":0.0,"publicationDate":"2023-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42666536","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Competing endogenous RNAs (ceRNAs) have been reported to act as sponges for microRNAs (miRNAs). To date, however, the mechanisms underlying ceRNA involvement in PAH have not been investigated. This study aimed to construct a PAH-related ceRNA network to further explore the mechanisms of PAH. Methods: A probe reannotation was conducted to identify the long non-coding RNAs (lncRNAs) and messenger RNAs (mRNAs) involved in PAH. Based on the reannotation results, the “limma” package was used to identify the differentially expressed genes (DEGs) and lncRNAs. The miRcode database was used to predict the lncRNA–miRNA interactions. Then, the mRNAs targeted by the miRNAs were predicted by using TargetScan, miRTarBase, and miRDB. Based on the above interactions, a ceRNA network was constructed, which was mapped and visualized with Cytoscape 3.6.1 software. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses were performed using the database. To predict possible drugs or molecules that may mitigate PAH, C-Map analysis was applied to find relevant molecular compounds that can reverse the expression of DEGs in cell lines. Results: The ceRNA network consisted of 174 nodes and 304 links, which included 10 lncRNAs, 23 miRNAs, and 53 mRNAs. The hub genes of the ceRNA network for PAH included hsa-miR-17-5p, hsa-miR-20b-5p, MEG3, HCP5, hsa-miR-27a-3p, hsa-miR-107, hsa-miR-142-3p, hsa-miR-363-3p, hsa-miR-301b-3p, and hsa-miR-23b-3p.

Methods: PubMed, Embase, Cochrane Library, WanFang Data, and the China National Knowledge Infrastructure database were searched from the establishment of the database to December 31, 2021, to identify randomized, double-blind trials that examined the effect of berberine alone or as add-on treatment on blood glucose, blood lipids, and blood pressure with an intervention period of at least 3 months. Two researchers independently screened articles, extracted data, and assessed the quality of each study according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The efficacy outcomes included fasting blood glucose (FPG), 2-hour post-prandial glucose (2hPG), glycated hemoglobin (HbA1c), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), and diastolic blood pressure (DBP). The safety outcome was the incidence of the total number of adverse events. Results: A total of 17 articles enrolling 1,485 participants were included in the meta-analysis. The intervention duration ranged from 12 to 24 weeks. Sixteen trials reported results for blood glucose, 14 trials reported results for blood lipids, and 7 reported results for blood pressure. Compared with placebo or baseline treatment, berberine alone or as add-on therapy significantly reduced FPG (by 0.35 mmol/L; 95% confidence interval (CI): 0.13–0.58 mmol/L; P = 0.002; I2 = 89.0%, n = 16), 2hPG (by 1.50 mmol/L; 95% CI: 0.50–2.49 mmol/L, P = 0.003, I2 = 84.1%, n = 4), HbA1c (by 0.45%, 95% CI: 0.24%–0.65%, P < 0.001, I2 = 82.8%, n = 9), TC (by 0.48 mmol/L; 95% CI: 0.36–0.60 mmol/L, P < 0.001, I2 = 72.3%, n = 13), TG (by 0.22 mmol/L; 95% CI: 0.13–0.31 mmol/L, P < 0.001, I2 = 57.1%, n = 14), and LDL-C (by 0.41 mmol/L; 95% CI: 0.34–0.48 mmol/L, P < 0.001, I2 = 35.0%, n = 12). The effect on blood glucose and blood lipids remained consistent when confined to high-quality trials. There is no significant effect of berberine treatment on HDL-C, SBP, and DBP. The incidence of the total number of adverse events was similar between the berberine group and the control group (risk ratio (RR) = 1.00, 95% CI: 0.84–1.19, P = 0.961). Gastrointestinal disorder was the most common adverse event in the berberine group and most adverse events were alleviated or disappeared as the dose was decreased or the intervention time was prolonged. Conclusions: Short-term berberine treatment significantly improved blood glucose and blood lipid profiles without raising safety concerns. A rigorously designed randomized controlled trial could be considered to examine the feasibility of the long-term application of berberine treatment in the prevention of cardiovascular disease.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"3 1","pages":"112 - 121"},"PeriodicalIF":0.0,"publicationDate":"2023-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41447209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: From September 2007 to January 2009, 1,859 subjects in Pingguoyuan communities in Beijing were initially screened. After excluding those with bedridden status, mental illness, severe systemic diseases, and missing data, 1,680 subjects were recruited for follow up. All recruited subjects were followed up from February 2013 to September 2013 (181 subjects were lost to follow-up) and from June 2017 to September 2018 (174 subjects were lost to follow up). Finally, 1,325 subjects were included in the study. General demographic characteristics, lifestyle and behaviors, disease history and use of medication was collected. Levels of total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fast blood glucose, RLP-C, low-density lipoprotein triglycerides and PCSK9 were measured. The levels of RLP-C (low: RLP-C ≤ 157 mg/L; high: RLP-C > 157 mg/L) and PCSK9 (low: PCSK9 ≤ 135.87 μg/L; high: PCSK9 > 135.87 μg/L) were represented using quartiles. Subjects were categorized into 4 groups according to their RLP-C and PCSK9 levels: Q4, high levels of RLP-C with high levels of PCSK9; Q3, high levels of RLP-C with low levels of PCSK9; Q2, low levels of RLP-C with high levels of PCSK9; and Q1, low levels of RLP-C with low levels of PCSK9. The association of RLP-C with MACEs in subjects with different PCSK9 levels was evaluated. Results: After a median follow-up of 9.5 years, 1,325 subjects were included in the study and a total of 191 MACEs had occurred. The incidence of MACEs was higher in the RLP-C > 157 mg/L group than the RLP-C ≤ 157 mg/L group (18.40% vs. 10.42%). Cox proportional hazards regression model analysis showed that increased RLP-C levels were associated with an increased risk of MACEs (hazard ratio: 1.405; 95% confidence interval: 1.005–1.964; P < 0.005). The incidence of MACEs was higher in the high RLP-C/PCSK9 group vs. the low RLP-C/PCSK9 group (20.68% vs. 8.76%). Cox proportional hazards regression model analysis showed that RLP-C was associated with an increased risk of MACEs in subjects with high PCSK9 levels independent of traditional risk factors (hazard ratio: 1.791; 95% confidence interval: 1.168–2.825; P = 0.001), but not in those with low PCSK9 levels. Conclusions: RLP-C was identified as a risk factor for MACEs, particularly in subjects with high PCSK9 levels. Lowering PCSK9 levels may reduce residual risk in subjects with elevated plasma RLP-C levels.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"3 1","pages":"159 - 165"},"PeriodicalIF":0.0,"publicationDate":"2023-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44250718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
