However, the optimal therapeutic regimen for patients undergoing transcatheter aortic valve implantation/replacement (TAVI/TAVR) remains unclear. The purpose of this study was to compare the efficacy and safety of various antithrombotic therapies following TAVI/TAVR. Methods: Relevant clinical trials evaluating the effect of anticoagulation or antiplatelet regimens on patients after TAVI/TAVR from inception to September 2020 were identified using the PubMed, EMBASE, and the Cochrane Library databases. The inclusion criteria including (1) all patients underwent TAVI/TAVR; (2) the interventions were antithrombotic strategies that prevent the occurrence of thrombotic events in patients; (3) randomized controlled trials or prospective observational studies; and (4) investigation of at least 1 outcome with a follow-up period of ≥3 months. The exclusion criteria including (1) research content was identical or irrelevant to the purpose of the present study; (2) lack of the required outcome index or availability of fragmentary original information; and (3) the full text is not available. The major outcomes were all-cause mortality, thromboembolic complications, and bleeding events. The Cochrane Collaboration's tool and the Newcastle-Ottawa Scale were used for assessing the risk of bias in included studies. Results: Thirteen studies (3 randomized controlled trials and 10 non-randomized studies) were identified, with a total of 23,497 patients. Four studies compared direct oral anticoagulants (DOACs) with warfarin, 1 study compared aspirin with warfarin, 6 studies compared aspirin plus clopidogrel (dual antiplatelet therapy (DAPT)) with aspirin monotherapy, and 2 studies compared DAPT and aspirin monotherapy with warfarin concurrently. There were no significant differences found between the DOAC and warfarin groups regarding all-cause mortality (risk ratio (RR): 1.03; 95% confidence interval (CI): 0.65–1.64; P = 0.909; Phet = 0.105), clinical adverse events (RR: 1.59; 95% CI: 0.99–2.58; P = 0.057; Phet = 0.738), or bleeding events (RR: 0.93; 95% CI: 0.78–1.11; P = 0.437; Phet = 0.338). The rates of all-cause mortality (RR: 0.71; 95% CI: 0.54–0.93; P = 0.012; Phet = 0.845) and bleeding events (RR: 0.43; 95% CI: 0.22–0.83; P = 0.012; Phet = 0.569) were lower in the aspirin group versus the warfarin group; however, there was no difference in the rate of clinical adverse events (RR: 0.38; 95% CI: 0.14–1.07; P = 0.068; Phet = 0.593). The DAPT group had an advantage versus the aspirin group in all-cause mortality (RR: 0.89; 95% CI: 0.82–0.98; P = 0.013; Phet = 0.299); however, the incidence of bleeding events (RR: 2.06; 95% CI: 1.39–3.07; P < 0.001; Phet = 0.001) exhibited an increasing trend.

As with other coronaviruses, SARS-CoV-2 infection damages not only the lungs but also the heart and many other organs that express angiotensin-converting enzyme 2 (ACE2), a receptor for SARS-CoV-2. COVID-19 has upended lives worldwide. Dietary behaviors have been altered such that they favor metabolic and cardiovascular complications, while patients have avoided hospital visits because of limited resources and the fear of infection, thereby increasing out-hospital mortality due to delayed diagnosis and treatment. Clinical observations show that sex, age, and race all influence the risk for SARS-CoV-2 infection, as do hypertension, obesity, and pre-existing cardiovascular conditions. Many hospitalized COVID-19 patients suffer cardiac injury, acute coronary syndromes, or cardiac arrhythmia. SARS-CoV-2 infection may lead to cardiomyocyte apoptosis and necrosis, endothelial cell damage and dysfunction, oxidative stress and reactive oxygen species production, vasoconstriction, fibrotic and thrombotic protein expression, vascular permeability and microvascular dysfunction, heart inflammatory cell accumulation and activation, and a cytokine storm. Current data indicate that COVID-19 patients with cardiovascular diseases should not discontinue many existing cardiovascular therapies such as ACE inhibitors, angiotensin receptor blockers, steroids, aspirin, statins, and PCSK9 inhibitors.

Methods: The study was conducted at 6 large PCI centers in China from January 1, 2013 to December 31, 2015. Demographic and clinical data were collected from medical records, prescription records, and laboratory reports of patients with symptoms of angina who underwent coronary angiography (CAG). Results: A total of 1713 patients were consecutively screened, 1600 of whom were included in the study. CAG showed that 300 patients had non-obstructive CAD while 1300 had obstructive CAD. Among the 300 patients with non-obstructive CAD, 203 displayed mild coronary stenosis (20%–49%) and 91 had normal coronary status (ie, <20% stenosis). Of the 1300 patients with obstructive CAD, 61.6% (801/1300) had typical symptoms of angina, compared with 49.3% (148/300) for patients with non-obstructive CAD. In addition, there were more women than men in the non-obstructive CAD group, whereas the reverse was observed among obstructive CAD patients. Conclusion: The prevalence of non-obstructive CAD in the Chinese population with coronary heart disease was estimated to be approximately 20%. Additionally, typical angina symptoms were correlated with obstructive CAD, whereas female gender was identified as a risk factor for non-obstructive CAD.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"1 1","pages":"223 - 227"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43698134","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}

Due to dietary habits, a majority of large-scale clinical trials examining FO and cardiovascular health have been conducted in the Caucasian populations. However, the effects of FO on cardiovascular inflammation indicators and blood lipid metabolism in the Chinese population remain unclear. This study aimed to perform a meta-analysis to elucidate the impact of FO on cardiovascular health in the Chinese population. Methods: Web searches were utilized to locate records of clinical trials related to cardiovascular health and consumption of FO capsules or fish containing omega-3 in several databases, including PubMed, Medline, Embase, Cochrane Library, CNKI, and ClinicalTrial.gov, etc. We obtained lipid metabolism and related proinflammatory markers as the study outcome. We used Review Manager 5.4 and Stata 16 for the statistical analysis. If the I2 ≥ 30%, a random effects model was used, and if the I2 < 30%, a fixed effects model was used. Results: Twenty eligible trials were shortlisted from >1000 records. The meta-analysis revealed that supplementation with eicosapentaenoic acid and docosahexaenoic acid reduced systolic blood pressure by 1.88  mmHg (95% CI: −4.97 to −1.20, P = 0.23), diastolic blood pressure by 0.86  mmHg (95% CI: −1.79 to 0.06, P = 0.07), fasting blood glucose by 0.05 mmol/L (95% CI: −0.16 to 0.06, P = 0.40), and low-density lipoprotein-cholesterol by 0.12  mmol/L (95% CI: −0.23 to −0.01, P = 0.04), when compared to placebo. However, these supplements increased high-density lipoprotein-cholesterol by 0.03  mmol/L (95% CI: 0.01 to 0.05, P < 0.001), when compared to placebo. Dose subgroup analyses examining total cholesterol found that the low-dose group (mean difference = −0.44, 95% CI: −0.55 to −0.34, P < 0.001) demonstrated the best results. Further, results from dose subgroup analyses showed that the all-dose group demonstrated a decrease in tumor necrosis factor (TNF-α) levels among the study subjects, when compared to other groups.

Methods: This cross-sectional study included 8795 normal-weight participants aged 20 to 79 years from the 2009–2018 US National Health and Nutrition Examination Survey. The demographic characteristics and cardiometabolic risk factors across waist circumference quartiles were summarized. We used adjusted multivariate logistic regression models, subgroup analysis, and restricted cubic spline to analyze the association between waist circumference and the prevalence of hypertension. Thereafter, we used the random forest supervised machine learning method, together with least absolute shrinkage and selection operator regression, to select hypertension-related features and created a predictive model based on regression analysis to identify hypertension in normal-weight individuals. Results: Waist circumference was positively correlated with hypertension in the non-adjusted, minimally adjusted, and fully adjusted models, with odds ratios (95% confidence interval) of 2.28 (2.14–2.44), 1.27 (1.12–1.44), and 1.27 (1.12–1.44), respectively. In the fully adjusted model, participants in the highest waist circumference quartile had a higher risk of hypertension relative to those in the lowest quartile, with an odds ratio (95% confidence interval) of 3.87 (1.59–10.34).

The prognostic importance of liver fibrosis scores (LFSs) has previously been reported in various CVDs. We hypothesized that LFSs might also be useful predictors for RCVEs in patients with prior cardiovascular events (CVEs). Herein, we aimed to evaluate the associations of LFSs with RCVEs in a large, real-world cohort of coronary artery disease (CAD) patients with a prior CVE. Methods: In this multicenter prospective study, 6527 consecutive patients with angiography-diagnosed CAD who had experienced a prior CVE (acute coronary syndrome, stroke, percutaneous coronary intervention, or coronary artery bypass grafting) were enrolled. LFSs were computed according to the published formulas: non-alcoholic fatty liver disease fibrosis score (NFS) includes age, body mass index (BMI), impaired fasting glycemia or diabetes mellitus (DM), aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio, platelets, and albumin; fibrosis-4 (FIB-4) includes age, AST, ALT, and platelets; Forns score includes age, gamma-glutamyltransferase (GGT), and platelets; BARD includes BMI, AST/ALT ratio, and DM; GGT/platelet ratio includes GGT and platelets; AST/ALT ratio includes AST and ALT; and AST/platelet ratio index includes AST and platelets. The originally reported cutoffs were used for the categorization of low-, intermediate-, and high-score subgroups. All patients were followed up for the occurrence of RCVEs (comprising cardiovascular death, non-fatal myocardial infarction, and stroke). Cox and Poisson regression analyses were used to assess the relationship of baseline LFSs with the risk of RCVE. Results: During a mean follow-up of (54.67 ± 18.80) months, 532 (8.2%) RCVEs were recorded. Intermediate and high NFS, FIB-4, Forns, and BARD scores were independently associated with an increased risk of RCVE (hazard ratios ranging from 1.42 to 1.75 for intermediate scores and 1.35 to 2.52 for high scores). In the subgroup analyses of sex, age, BMI, DM, and hypertension status, the increased risk of RCVEs with high LFSs (NFS, FIB-4, Forns, and BARD) was maintained across the different subgroups (all P < 0.05). Conclusion: This study showed that LFSs are indeed independently associated with RCVEs, suggesting that LFSs may be used as novel tools for risk stratification in CAD patients with a prior CVE.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"1 1","pages":"214 - 222"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44451704","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}

Silent information regulator 6 (SIRT6) exerts beneficial effects against cardiovascular diseases. This study is aimed to investigate whether the direct regulation of myocardial SIRT6 signaling affects cardiac performance in the case of diabetes. Meanwhile, we sought to explore the underlying mechanisms. Methods: Sprague Dawley (SD) rats were used in this experiment. Briefly, type 2 diabetic animal model was generated by streptozotocin administration along with feeding a high-fat diet. The SD rats were randomly assigned to non-diabetic group, diabetic group, diabetic injected with empty adenoviral vectors group and diabetic injected with adenoviral vectors expressing SIRT6 group (n = 10, respectively). The animals were kept for another 4 weeks before sacrifice. Cardiac performance was evaluated by echocardiography. Myocardial fibrosis was determined by Masson's trichrome staining. Myocardial SIRT6 signaling and fibrosis related molecules were measured by western blotting. Results: The diabetic myocardium exhibited markedly enhanced TGFβ1-Smad2/3-induced myocardial fibrosis and reduced SIRT6 and AMP-activated protein kinase (AMPK) signaling. After 4 weeks of SIRT6 adenoviral vector infection, myocardial tissues exhibited markedly enhanced SIRT6 and AMPK signaling. Additionally, myocardial fibrosis and TGFβ1-Smad2/3 signaling were both attenuated in the diabetic injected with adenoviral vectors expressing SIRT6 group. Conclusions: SIRT6-AMPK signaling suppressed the progression of tissue fibrosis in diabetes mellitus rats by inhibiting TGFβ1 and its downstream effector Smad2/3. SIRT6 might serve as an alternative therapeutic target for diabetes-related cardiovascular diseases.","PeriodicalId":72524,"journal":{"name":"Cardiology discovery","volume":"2 1","pages":"6 - 12"},"PeriodicalIF":0.0,"publicationDate":"2021-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49361820","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}
