Background Patients with acute myocardial infarction (AMI) and bundle-branch block have poor prognoses. The new European Society of Cardiology guideline suggests a primary percutaneous coronary intervention strategy when persistent ischemic symptoms occur in patients with persistent ischemic symptoms and right bundle-branch block (RBBB), but the level of evidence is not high. In fact, the presence of RBBB may lead to the misdiagnosis of transmural ischemia and mask the early diagnosis of ST-elevation myocardial infarction. Moreover, new-onset RBBB is occasionally caused by AMI. Our study aims to investigate the prognostic value of new-onset RBBB in AMI. Methods and Results We conducted a meta-analysis of studies to evaluate the prognostic value of RBBB in AMI patients. Of 914 primary records, five studies and 874 MI patients were included for meta-analysis. Compared with previous RBBB, AMI patients with new-onset RBBB had a higher risk of long-term mortality (RR, 1.66, 95% CI [1.31–2.09], I2 = 0.0%, p = 0.000, n = 2), ventricular arrhythmia (RR, 4.86, 95% CI [2.10–11.27], I2 = 0.0%, p = 0.000, n = 3), and cardiogenic shock (RR, 2.76, 95% CI [1.66–4.59], I2 = 0.0%, p = 0.000, n = 3), but a lower risk of heart failure (RR, 0.66, 95% CI [0.52–0.85], I2 = 2.50%, p = 0.001, n = 4). Compared with AMI patients with new-onset permanent RBBB, patients with new-onset transient RBBB had a lower risk of short-term mortality (RR, 0.20, 95% CI [0.11–0.37], I2 = 44.1%, p = 0.000, n = 4). Conclusion New-onset RBBB is likely to increase long-term mortality, ventricular arrhythmia, and cardiogenic shock, but not heart failure in AMI patients. AMI patients with new-onset transient RBBB have a lower risk of short-term mortality than those with new-onset permanent RBBB. Revascularization therapies should be considered when persistent ischemic symptoms occur in patients with RBBB, especially new-onset RBBB.

Objectives: Out-of-hour admission (on weekends, holidays, and weekday nights) has been associated with higher mortality in patients with acute myocardial infarction (AMI). We conducted a meta-analysis to verify the association between out-of-hour admission and mortality (both short- and long-term) in AMI patients.Design: This Systematic review and meta-analysis of cohort studies.Data Sources: PubMed and EMBASE were searched from inception to 27 May 2021.Eligibility Criteria for Selected Studies: Studies of any design examined the potential association between out-of-hour admission and mortality in AMI.Data Extraction and Synthesis: In total, 2 investigators extracted the data and evaluated the risk of bias. Analysis was conducted using a random-effects model. The results are shown as odds ratios [ORs] with 95% confidence intervals (CIs). I2 value was used to estimate heterogeneity. Grading of Recommendations Assessment, Development, and Evaluation was used to assess the certainty of the evidence.Results: The final analysis included 45 articles and 15,346,544 patients. Short-term mortality (defined as either in-hospital or 30-day mortality) was reported in 42 articles (15,340,220 patients). Out-of-hour admission was associated with higher short-term mortality (OR 1.04; 95%CI 1.02–1.05; I2 = 69.2%) but there was a significant statistical indication for publication bias (modified Macaskill's test P < 0.001). One-year mortality was reported in 10 articles (1,386,837 patients). Out-of-hour admission was also associated with significantly increased long-term mortality (OR 1.03; 95%CI 1.01–1.04; I2 = 66.6%), with no statistical indication of publication bias (p = 0.207). In the exploratory subgroup analysis, the intervention effect for short-term mortality was pronounced among patients in different regions (p = 0.04 for interaction) and socio-economic levels (p = 0.007 for interaction) and long-term mortality was pronounced among patients with different type of AMI (p = 0.0008 for interaction) or on different types of out-to-hour admission (p = 0.006 for interaction).Conclusion: Out-of-hour admission may be associated with an increased risk of both short- and long-term mortality in AMI patients.Trial Registration: PROSPERO (CRD42020182364).

Objective: In year 2016, quick Sepsis-Related Organ Failure Assessment (qSOFA) was introduced as a better sepsis screening tool compared to systemic inflammatory response syndrome (SIRS). The purpose of this systematic review and meta-analysis is to evaluate the ability of the qSOFA in predicting short- and long-term mortality among patients outside the intensive care unit setting. Method: Studies reporting on the qSOFA and mortality from MEDLINE (published between 1946 and 15th December 2017) and SCOPUS (published before 15th December 2017). Hand-checking of the references of relevant articles was carried out. Studies were included if they involved inclusion of patients presenting to the ED; usage of Sepsis-3 definition with suspected infection; usage of qSOFA score for mortality prognostication; and written in English. Study details, patient demographics, qSOFA scores, short-term (<30 days) and long-term (≥30 days) mortality were extracted. Two reviewers conducted all reviews and data extraction independently. Results and Discussion: A total of 39 studies met the selection criteria for full text review and only 36 studies were inclided. Data on qSOFA scores and mortality rate were extracted from 36 studies from 15 countries. The pooled odds ratio was 5.5 and 4.7 for short-term and long-term mortality respectively. The overall pooled sensitivity and specificity for the qSOFA was 48% and 85% for short-term mortality and 32% and 92% for long-term mortality, respectively. Studies reporting on short-term mortality were heterogeneous (Tau=24%, I2=94%, P<0.001), while long-term mortality studies were homogenous (Tau=0%, I2<0.001, P=0.52). The factors contributing to heterogeneity may be wide age group, various clinical settings, variation in the timing of qSOFA scoring, and broad range of clinical diagnosis and criteria. There was no publication bias for short-term mortality analysis. Conclusion: qSOFA score showed a poor sensitivity but moderate specificity for both short and long-term mortality prediction in patients with suspected infection. qSOFA score may be a cost-effective tool for sepsis prognostication outside of the ICU setting.

Abstract Background: The association between the lymphocyte-to-monocyte ratio (LMR) and prognosis of patients with acute coronary syndrome (ACS) is not fully understood. We performed this systematic review and meta-analysis to evaluate the correlation between LMR and mortality or major adverse cardiac events (MACE) in patients with ACS. Methods: A systematic search was performed in PubMed, MEDLINE, EMBASE, the Cochrane Library, Scopus and Web of science. The association between LMR and mortality or MACE was analyzed in patients with ACS. The search was updated to April 15, 2020. Results: A total of 5 studies comprising 4343 patients were included in this meta-analysis. The results showed that lower LMR predicted short-term mortality/MACE (hazard ratio [HR] = 3.44, 95% confidence interval [CI]: 1.46–8.14, P < 0.05) and higher long-term mortality/MACE (HR = 1.70, 95% CI: 1.36– 2.13, P < 0.05). According to our subgroup analysis, there is still has a statistical significance for LMR to predict long-term mortality/MACE in any subgroups. Conclusions: This study suggested that lower LMR value might be associated with higher short-term mortality/MACE and long-term mortality/MACE in ACS patients. Especially for younger ACS patients, low LMR was more closely associated with poor prognosis.

<b><i>Introduction:</i></b> Soluble suppression of tumorigenicity-2 (sST2) has been considered as a prognostic factor of cardiovascular disease. However, the prognostic value of sST2 concentration in chronic heart failure remains to be summarized. <b><i>Methods:</i></b> We searched PubMed, Embase, and Web of Science for eligible studies up to January 1, 2020. Data extracted from articles and provided by authors were used in agreement with the PRISMA statement. The endpoints were all-cause mortality (ACM), cardiovascular mortality (CVM)/heart failure-related hospitalization (HFH), and all-cause mortality (ACM)/heart failure-related readmission (HFR). <b><i>Results:</i></b> A total of 11 studies with 5,121 participants were included in this analysis. Higher concentration of sST2 predicted the incidence of long-term ACM (hazard ratio [HR]: 1.03, 95% confidence interval [CI]: 1.02–1.04), long-term ACM/HFR (HR: 1.42, CI: 1.27–1.59), and long-term CVM/HFH (HR: 2.25, CI: 1.82–2.79), regardless of short-term ACM/HFR (HR: 2.31, CI: 0.71–7.49). <b><i>Conclusion:</i></b> Higher sST2 concentration at baseline is associated with increasing risk of long-term ACM, ACM/HFR, and CVM/HFH and can be a tool for the prognosis of chronic heart failure.

Abstract Aims to evaluate prognostic significance of metabolic syndrome (MetS) in patients undergoing carotid artery revascularisation. Methods A systematic review and meta-analysis was performed in compliance with PRISMA standards to evaluate prognostic significance of MetS in patients undergoing carotid endarterectomy or carotid stenting. Short-term (&lt;30 days) postoperative outcomes (all-cause mortality, stroke or transient ischaemic attack (TIA), myocardial infarction, major adverse events) and long-term outcomes (restenosis, all-cause mortality, stroke or TIA, myocardial infarction, major adverse events) were considered as outcomes of interest. Random effects modelling was applied for the analyses. Results Analysis of 3721 patients from five cohort studies showed no difference between the MetS and no MetS groups in terms of the following short-term outcomes: all-cause mortality (OR: 1.67,P=0.32), stroke or TIA (OR: 2.44,P=0.06), myocardial infarction (OR: 1.01,P=0.96), major adverse events (OR: 1.23, P = 0.66). In terms of long-term outcomes, MetS was associated with higher risk of restenosis (OR: 1.75,P=0.02), myocardial infarction (OR: 2.12,P=0.04), and major adverse events (OR: 1.30, P = 0.009) but there was no difference between the two groups in terms of all-cause mortality (OR: 1.11, P = 0.25), and stroke or TIA (OR: 1.24, P = 0.33). The quality and certainty of the available evidence were judged to be moderate. Conclusions The best available evidence suggest that although MetS may not affect the short-term postoperative morbidity and mortality outcomes in patients undergoing carotid revascularisation, it may result in higher risks of restenosis, myocardial infarction and major adverse events in the long-term. Evidence from large prospective cohort studies are required for more robust conclusions.

Abstract Introduction Women have been less represented in every NSTEMI clinical trial. Moreover, it has been observed that this group of patients have usually received less revascularization and evidence based treatment, therefore presenting with a greater long and short-term mortality. Purpose The purpose of our study is to analyze the presence of differences in baseline characteristics, management and outcome of women with NSTEMI during the last decade. Methods and results Retrospective study including 861 women admitted for NSTEMI between 2003 and 2015 in our center. We divided 2 groups according to hospitalization period (2003–2008 and 2009–2015) with a medium follow up of 4.5±2.9 years. Baseline characteristics and treatment at discharge are described on table 1. We noticed a greater use of statins and ACEI/ARB on the second period as well as a greater percentage of patients receiving early revascularization. It is remarkable on women a non-significant reduction of heart failure hospitalization at follow up (6.8% vs 4.5%; p=0.091), neither differences on 30-day mortality (1.3% vs 0,4%) or 1-year mortality (7.1% vs 5.8%). However, long-term mortality for the second group is reduced (HR 0.69; CI 95% 0.52–0.89), even after performing a multivariate analysis (HR 0.64; CI 95% 0.48–0.85). Characteristic Population (n=861) 2003–2008 (n=395) 2009–2015 (n=466) p-value Age (years) 73±12 73±12 72±12 0.316 Hypertension 629 (73.1%) 285 (72.2%) 344 (73.8%) 0.318 Hypercholesterolemia 414 (48.1%) 190 (48.1%) 224 (48.1%) 0.523 Killip class 0.292   I 664 (77.1%) 299 (75.7%) 365 (78.3%)   II 143 (16.6%) 74 (18.7%) 69 (14.8%)   III 47 (5.5%) 20 (5.1%) 27 (5.8%)   IV 4 (0.5%) 2 (0.5%) 2 (0.4) GRACE score 129±32 130±37 128±33 0.897 Early PCI 249 (29.3%) 76 (19.2%) 173 (38.0%) <0.005 Treatment at discharge   AAS 698 (81.1%) 313 (79.2%) 385 (82.6%) 0.120   Clopidogrel 465 (54.0%) 221 (55.9%) 244 (52.4%) 0.162   ACEI/ARB 466 (54.1%) 191 (48.4%) 275 (59.0%) 0.001   Beta-blocker 509 (59.1%) 238 (60.3%) 271 (58.2%) 0.290   Statins 643 (74.7%) 275 (69.6%) 368 (79.0%) 0.001 Conclusions In recent years, early interventionist management and greater use of evidence-based therapies have been observed in women with NSTEMI. This has been associated with a lesser long-term mortality, although short-term events have remained the same.
