All Cause Mortality

Introduction: Due to shared risk factors and pathophysiology, atrial fibrillation (AF) and heart failure with preserved ejection fraction (HFpEF) frequently coexist. However, the prognostic implications of AF in HFpEF are unclear with conflicting data. Herein, we conducted a systematic review and meta-analysis to assess the impact of concomitant AF on cardiovascular outcomes in patients with HFpEF. Methods: PubMed, Scopus, and Google Scholar were comprehensively searched through May 7th, 2020 for studies comparing outcomes of HFpEF patients with and without AF. Outcomes assessed were all-cause mortality and a composite of HF hospitalization or cardiovascular (CV) mortality. Data from selected studies were abstracted and pooled using a random-effects meta-analysis to calculate odds ratios (ORs) and 95% confidence intervals [CIs] for each of the outcomes. Results: Our final analysis included 10 studies with 27,440 HFpEF patients (43.2% with AF). AF was associated with significantly increased risk of all-cause mortality (OR 1.37 [1.17-1.61], p < 0.001, Fig. 1A), HF hospitalization or CV mortality (OR 1.66 [1.16-2.36], p = 0.005, Fig. 1B), and HF hospitalization alone (OR 1.34 [1.03-1.76], p = 0.03, Fig. 1C). However, AF was not associated with excess risk of CV mortality alone (OR 1.10 [0.79-1.52], p = 0.57, Fig. 1D). Conclusions: In patients with HFpEF, concomitant AF is associated with an increased risk of all-cause mortality and HF hospitalization. Further research into the mechanisms and interventions to mitigate this excess risk is necessary.

The Impact

Abstract Background Since the inception of clinical guidelines on the management of patients with acute coronary syndrome (ACS), betablocker therapy has been included as a class I recommendation. However, most studies evaluating betablockers in ACS were conducted in the pre-reperfusion era. Currently, the great majority of patients undergo reperfusion and secondary prevention therapy has evolved; the impact of treatment with a betablocker in these patients may be different. Purpose We conducted a systematic review and meta-analysis to evaluate the impact of betablockers on mortality in patients after an ACS in the reperfusion era. Methods We searched MEDLINE, EMBASE, and Cochrane Central Registry of Controlled Trials for RCTs from inception to September 2019. We included randomized controlled trials comparing betablockers to no betablockers in adult patients presenting with an ACS. Independently and in duplicate, we screened titles and abstracts, reviewed the full-text report of potentially eligible studies and extracted data. Two reviewers also evaluated the risk of bias in duplicate. Disagreements were addressed by consensus. We considered trials to be conducted in the reperfusion era if reperfusion was attempted in more than 50% of patients, either with thrombolytics or primary angioplasty. Our primary outcome of interest was all-cause mortality. Secondary outcomes included hospitalization for heart failure, nonfatal myocardial infarction, stroke and cardiogenic shock. We pooled trial outcomes using a fixed effects model. The study protocol is registered with PROSPERO (CRD42019143158). Results After the initial screening of 10,969 references and full-text review of 176 articles, nine RCTs comprising a total of 49,639 patients with ACS were eligible for the final analysis. Predominantly, these patients presented with ST elevation myocardial infarction. Treatment with a betablocker did not improve all-cause mortality at 30 days (risk ratio (RR) 0.98 [95% CI 0.92–1.04], I2=44%), or at longest follow up (up to three years) with RR 0.97 ([95% CI 0.91–1.03], I2=0%). Betablocker therapy was associated with an increased risk of HF hospitalization (RR 1.10 [95% CI 1.05–1.15], I2=52%) and cardiogenic shock during index hospitalization (RR 1.29, [95% CI 1.18–1.40], I2=0%). However, betablocker therapy reduced the risk of nonfatal myocardial infarction (RR 0.72 [95% CI 0.63–0.83], I2=0%); it did not impact the risk of stroke (RR 1.13 [95% CI 0.95–1.35], I2=0%). Conclusion In the reperfusion era, betablocker therapy after an ACS does not appear to improve short or long-term survival. Although betablocker therapy was associated with a reduction in nonfatal myocardial infarction, it increased the risk of heart failure hospitalization and cardiogenic shock. In light of these findings, clinical guidelines should reconsider the strength of their recommendation for betablocker use in the ACS population until further contemporary evidence is available.

ObjectiveHeart failure is a prothrombotic state, and it has been hypothesised that thrombosis and embolism cause non-fatal and fatal events in heart failure and reduced ejection fraction (HFrEF). We sought to determine the effect of anticoagulant therapy on clinical outcomes in patients with HFrEF who are in sinus rhythm.MethodsWe conducted an updated systematic review and meta-analysis to examine the effect of anticoagulation therapy in patients with HFrEF in sinus rhythm. Our analysis compared patients randomised to anticoagulant therapy with those randomised to antiplatelet therapy, placebo or control, and examined the endpoints of all-cause mortality, (re)hospitalisation for worsening heart failure, non-fatal myocardial infarction, non-fatal stroke of any aetiology and major haemorrhage.ResultsFive trials were identified that met the prespecified search criteria. Compared with control therapy, anticoagulant treatment did not reduce all-cause mortality (risk ratio [RR] 0.99, 95% CI 0.90 to 1.08), (re)hospitalisation for heart failure (RR 0.97, 95% CI 0.82 to 1.13) or non-fatal myocardial infarction (RR 0.92, 95% CI 0.75 to 1.13). Anticoagulation did reduce the rate of non-fatal stroke (RR 0.63, 95% CI 0.49 to 0.81, p=0.001), but this was offset by an increase in the incidence of major haemorrhage (RR 1.88, 95% CI 1.49 to 2.38, p=0.001).ConclusionsOur meta-analysis provides evidence to oppose the hypothesis that thrombosis or embolism plays an important role in the morbidity and mortality associated with HFrEF, with the exception of stroke-related morbidity.

ObjectiveTo examine the effect of HLP, defined as having a pre-existing or a new in-hospital diagnosis based on low density lipoprotein cholesterol (LDL-C) level ≥100 mg/dL during index hospitalisation or within the preceding 6 months, on all-cause mortality after hospitalisation for acute myocardial infarction (AMI) or acute decompensated heart failure (ADHF) and to determine whether HLP modifies mortality associations of other competing comorbidities. A systematic review and meta-analysis to place the current findings in the context of published literature.DesignRetrospective study, 1:1 propensity-score matching cohorts; a meta-analysis.SettingLarge academic centre, 1996–2015.ParticipantsHospitalised patients with AMI or ADHF.Main outcomes and measuresAll-cause mortality and meta-analysis of relative risks (RR).ResultsUnmatched cohorts: 13 680 patients with AMI (age (mean) 68.5 ± (SD) 13.7 years; 7894 (58%) with HLP) and 9717 patients with ADHF (age, 73.1±13.7 years; 3668 (38%) with HLP). In matched cohorts, the mortality was lower in AMI patients (n=4348 pairs) with HLP versus no HLP, 5.9 versus 8.6/100 person-years of follow-up, respectively (HR 0.76, 95% CI 0.72 to 0.80). A similar mortality reduction occurred in matched ADHF patients (n=2879 pairs) with or without HLP (12.4 vs 16.3 deaths/100 person-years; HR 0.80, 95% CI 0.75 to 0.86). HRs showed modest reductions when HLP occurred concurrently with other comorbidities. Meta-analyses of nine observational studies showed that HLP was associated with a lower mortality at ≥2 years after incident AMI or ADHF (AMI: RR 0.72, 95% CI 0.69 to 0.76; heart failure (HF): RR 0.67, 95% CI 0.55 to 0.81).ConclusionsAmong matched AMI and ADHF cohorts, concurrent HLP, compared with no HLP, was associated with a lower mortality and attenuation of mortality associations with other competing comorbidities. These findings were supported by a systematic review and meta-analysis.

AbstractBackgroundImmune checkpoint inhibitors (ICIs) are novel therapeutic agents used for various types of cancer. ICIs have revolutionized cancer treatment and improved clinical outcomes among cancer patients. However, immune-related adverse effects of ICI therapy are common. Cardiovascular immune-related adverse events (irAEs) are rare but potentially life-threatening complications. We aimed to estimate the incidence of cardiovascular irAEs among patients undergoing ICI therapy for various malignancies.MethodsWe conducted this systematic review and meta-analysis by searching PubMed, Cochrane CENTRAL, Web of Science, and SCOPUS databases for relevant interventional trials reporting cardiovascular irAEs. We performed a single-arm meta-analysis using OpenMeta [Analyst] software of the following outcomes: myocarditis, pericardial effusion, heart failure, cardiomyopathy, atrial fibrillation, myocardial infarction, and cardiac arrest. We assessed the heterogeneity using the I2 test and managed to solve it with Cochrane’s leave-one-out method. The risk of bias was performed with the Cochrane’s risk of bias tool.ResultsA total of 26 studies were included. The incidence of irAEs follows: myocarditis: 0.5% (95% CI [0.1%-0.9%]); pericardial effusion: 0.5% (95% CI [0.1%-1.0%]); heart failure: 0.3% (95% CI [0.0%-0.5%]); cardiomyopathy: 0.3% (95% CI [-0.1%-0.6%]); atrial fibrillation: 7.6% (95% CI [1.0%-14.1%]); myocardial infarction: 0.4% (95% CI [0.0%-0.7%]); and cardiac arrest: 0.4% (95% CI [0.1%-0.8%]).ConclusionThe most common cardiovascular irAEs were atrial fibrillation, myocarditis, and pericardial effusion. Although rare, data from post market surveillance will provide estimates of the long-term prevalence and prognosis in patients with ICI-associated cardiovascular complications.

Abstract Objective: The aim of this meta-analysis was to investigate the association between malnutrition assessed by the controlling nutritional status (CONUT) score and all-cause mortality in patients with heart failure. Design: Systematic review and meta-analysis. Settings: A comprehensively literature search of PubMed and Embase databases was performed until 30 November 2020. Studies reporting the utility of CONUT score in prediction of all-cause mortality among patients with heart failure were eligible. Patients with a CONUT score ≥2 are grouped as malnourished. Predictive values of the CONUT score were summarized by pooling the multivariable-adjusted risk ratios (RR) with 95 % CI for the malnourished v. normal nutritional status or per point CONUT score increase. Participants: Ten studies involving 5196 patients with heart failure. Results: Malnourished patients with heart failure conferred a higher risk of all-cause mortality (RR 1·92; 95 % CI 1·58, 2·34) compared with the normal nutritional status. Subgroup analysis showed the malnourished patients with heart failure had an increased risk of in-hospital mortality (RR 1·78; 95 % CI 1·29, 2·46) and follow-up mortality (RR 2·01; 95 % CI 1·58, 2·57). Moreover, per point increase in CONUT score significantly increased 16% risk of all-cause mortality during the follow-up. Conclusions: Malnutrition defined by the CONUT score is an independent predictor of all-cause mortality in patients with heart failure. Assessment of nutritional status using CONUT score would be helpful for improving risk stratification of heart failure.

Abstract Background Catheter ablation improves clinical outcomes in symptomatic atrial fibrillation (AF) patients with heart failure (HF) with reduced ejection fraction (HFrEF). However, the role of catheter ablation in HF patients with a preserved ejection fraction (HFpEF) is less clear. Purpose To determine the efficacy of catheter ablation of AF in patients with HFpEF relative to those with HFrEF. Methods We performed an extensive literature search and systematic review of studies that compared AF recurrence at one year after catheter ablation of AF in patients with HFpEF versus those with HFrEF. Risk ratio (RR) 95% confidence intervals were measured using the Mantel-Haenszel method for dichotomous variables, where a RR&lt;1.0 favors the HFpEF group. Results Four studies with a total of 563 patients were included, of which 312 had HFpEF and 251 had HFrEF. All patients included were undergoing first time catheter ablation of AF. Patients with HFpEF experienced similar recurrence of AF one year after ablation on or off antiarrhythmic drugs compared to those with HFrEF (RR 0.87; 95% CI 0.69–1.10, p=0.24), as shown in Figure 1. Recurrence of AF was assessed with electrocardiography, Holter monitoring, and/or event monitoring at scheduled follow-up visits and final follow-up. Conclusion Based on the results of this meta-analysis, catheter ablation of AF in patients with HFpEF appears as efficacious in maintaining sinus rhythm as in those with HFrEF.

Background: In patients with COVID-19, cardiovascular complications are common and associated with poor prognosis. Among these, an association between atrial fibrillation (AF) and COVID-19 has been described; however, the extent of this relationship is unclear. The aim of this study is to investigate the epidemiology of AF in COVID-19 patients and its impact on all-cause mortality. Methods: A systematic review and meta-analysis were performed and reported according to PRISMA guidelines, and a protocol for this study was registered on PROSPERO (CRD42021227950). PubMed and EMBASE were systematically searched for relevant studies. A random-effects model was used to estimate pooled odds ratios (OR) and 95% confidence intervals (CI). Results: Overall, 31 studies were included in the analysis, with a total number of 187,716 COVID-19 patients. The prevalence of AF was found to be as high as 8% of patients with COVID-19 (95% CI: 6.3–10.2%, 95% prediction intervals (PI): 2.0–27.1%), with a high degree of heterogeneity between studies; a multiple meta-regression model including geographical location, age, hypertension, and diabetes showed that these factors accounted for more than a third of the heterogeneity. AF COVID-19 patients were less likely to be female but more likely older, hypertensive, and with a critical status than those without AF. Patients with AF showed a significant increase in the risk of all-cause mortality (OR: 3.97, 95% CI: 2.76–5.71), with a high degree of heterogeneity. A sensitivity analysis focusing on new-onset AF showed the consistency of these results. Conclusions: Among COVID-19 patients, AF is found in 8% of patients. AF COVID-19 patients are older, more hypertensive, and more likely to have a critical status. In COVID-19 patients, AF is associated with a 4-fold higher risk of death. Further studies are needed to define the best treatment strategies to improve the prognosis of AF COVID-19 patients.
