Abstract
Atrial fibrillation (AF) can increase thrombosis, especially arterial thrombosis, and some studies show that AF patients have a higher risk of developing pulmonary embolism (PE). The objective of our study is to investigate whether there is a direct causal effect of AF on PE. A two-sample Mendelian randomization (MR) approach was utilized to determine whether there is a causal relationship between AF and PE. European population-based consortia provided statistical data on the associations between Single Nucleotide Polymorphisms (SNPs) and relevant traits. The AF dataset was obtained from genome-wide association studies (GWAS) comprising 60,620 cases and 970,216 controls, while a GWAS of 1846 cases and 461,164 controls identified genetic variations associated with PE. Estimation of the causal effect was mainly performed using the random effects inverse-variance weighted method (IVW). Additionally, other tests such as MR-Egger intercept, MR-PRESSO, Cochran's Q test, "Leave-one-out," and funnel plots were conducted to assess the extent of pleiotropy and heterogeneity. Using 70 SNPs, there was no evidence to suggest an association between genetically predicted AF and risk of PE with multiplicative random-effects IVW MR analysis (odds ratio = 1.0003, 95% confidence interval: 0.9998-1.0008, P = 0.20). A null association was also observed in other methods. MR-Egger regression and MR-PRESSO respectively showed no evidence of directional (intercept, - 2.25; P = 0.94) and horizontal(P-value in the global heterogeneity test = 0.99) pleiotropic effect across the genetic variants. No substantial evidence was found to support the causal role of AF in the development of PE.

Abstract
The conjunction of atrial fibrillation (AF) and venous thromboembolism (VTE) is common in clinical practice. Over the last 2 decades, a significant number of articles (2500) have been published about AF and VTE. To effectively analyze and present these vast amounts of information, this study uses bibliometric research methods to categorize and consolidate these publications. The number of publications has increased yearly, especially since 2012. The United States was the most prolific country, with 1054 studies published. The most productive institution was McMaster University. Gregory Y.H. Lip was the most prolific author. The keyword analysis identified that the research focuses from 2003 to 2014 were factor Xa inhibitor, dabigatran etexilate, direct thrombin inhibitor, double-blind, deep vein thrombosis, molecular weight heparin, stroke prevention, etc. From 2015 to 2016, research mainly focused on venous thromboembolism, antithrombotic therapy, anticoagulant, warfarin, atrial fibrillation, stroke, and pulmonary embolism. Studies during 2017 to 2022 focused on apixaban, direct oral anticoagulant, rivaroxaban, dabigatran, hemorrhage, edoxaban, medicine efficacy and safety, risk factors, clinical management, and vitamin K antagonists. Since 2018, novel oral anticoagulants have been the most commonly used keywords. On the whole, most studies of AF and VTE focus on pathogenesis and therapeutic drugs. The causal relationship between AF and VTE, the effectiveness and safety of novel oral anticoagulants in the treatments, the anticoagulant regimen of AF and VTE co-disease, and the treatment regimen for vulnerable populations such as the elderly or obese people were the focus of current research and will continue to be the central point of future research.

Abstract
BACKGROUND Pulmonary embolism (PE) is the third most common cause of cardiovascular death. Atrial fibrillation (AF) is the most common arrhythmia and is commonly detected in patients after embolic stroke. In this study, we set out to study if undiagnosed AF could be detected in patients with PE. In survivors of PE, persisting symptoms and exercise limitations are common. The disease burden of PE on quality of life (QoL) has received scarce attention. The primary aim was to study the prevalence of AF in patients with newly diagnosed PE. The secondary aim was to study QoL in PE patients. METHODS Patients with newly diagnosed acute PE were randomized 1:1 to long-term electrocardiogram (ECG) screening for AF (handheld ECG or ECG patch) or standard-of-care. The study participants were asked to complete RAND-36 questionnaires upon inclusion. RESULTS In total 89 PE patients (mean age 74.6 years) were included, and 40 out of these patients were randomized to AF screening. The study was terminated early due to futility when analysis 1 year after inclusion did not find any patients with newly detected AF.RAND-36 showed that QoL was affected in PE patients. Interestingly, sex differences were found; women had a significantly lower QoL in the dimensions of vitality (P = .006), general health (P = .039), and mental health (P = .041). CONCLUSION Screening for AF in PE patients did not yield a significant proportion of new cases. QoL is more affected in female patients with PE, and increased awareness of this is suggested.

Abstract
Background Atrial fibrillation (AF) may exist before or occur early in the course of pulmonary embolism (PE). We determined the PE outcomes based on the presence and timing of AF. Methods and Results Using the data from a multicenter PE registry, we identified 3 groups: (1) those with preexisting AF, (2) patients with new AF within 2 days from acute PE (incident AF), and (3) patients without AF. We assessed the 90-day and 1-year risk of mortality and stroke in patients with AF, compared with those without AF (reference group). Among 16 497 patients with PE, 792 had preexisting AF. These patients had increased odds of 90-day all-cause (odds ratio [OR], 2.81; 95% CI, 2.33-3.38) and PE-related mortality (OR, 2.38; 95% CI, 1.37-4.14) and increased 1-year hazard for ischemic stroke (hazard ratio, 5.48; 95% CI, 3.10-9.69) compared with those without AF. After multivariable adjustment, preexisting AF was associated with significantly increased odds of all-cause mortality (OR, 1.91; 95% CI, 1.57-2.32) but not PE-related mortality (OR, 1.50; 95% CI, 0.85-2.66). Among 16 497 patients with PE, 445 developed new incident AF within 2 days of acute PE. Incident AF was associated with increased odds of 90-day all-cause (OR, 2.28; 95% CI, 1.75-2.97) and PE-related (OR, 3.64; 95% CI, 2.01-6.59) mortality but not stroke. Findings were similar in multivariable analyses. Conclusions In patients with acute symptomatic PE, both preexisting AF and incident AF predict adverse clinical outcomes. The type of adverse outcomes may differ depending on the timing of AF onset.

Abstract
AIMS Atrial fibrillation (AF) is associated with arterial thromboembolism, mainly ischaemic stroke, while venous thromboembolism (VTE) in AF is less well studied. The aim of this study, therefore, was to examine the relationship between AF and VTE, including pulmonary embolism (PE) and deep venous thrombosis (DVT). METHODS AND RESULTS AF cases without previous VTE, ischaemic stroke or pulmonary arterial hypertension were identified from the Swedish Inpatient Registry between 1987 and 2013 and compared to two population controls per case without AF matched for age, sex, and county with respect to the incidence of VTE, PE, and DVT. In total, 463 244 AF cases were compared to 887 336 population controls. In both men and women, VTE rates were higher among AF patients the first 30 days after an AF diagnosis [40.2 vs. 5.7 in men and 55.7 vs. 6.6 in women per 1000 person-years at risk, respectively; hazard ratios 6.64 (95% confidence interval, 5.74-7.69) and 7.56 (6.47-8.83)]; and then decreasing, simultaneously with an increasing number of AF patients being treated with oral anticoagulation. VTE risk was similar to controls after 9 months in men but remained slightly elevated in women. CONCLUSION AF is strongly associated with an increased risk of VTE during the first months after diagnosis. Introduction of anticoagulant therapy soon after AF diagnosis might reduce the risk of VTE as well as of ischaemic stroke.

Abstract
BACKGROUND To investigate the impact of atrial fibrillation/flutter (AF) on adverse in-hospital outcomes in hospitalized surgical patients. METHODS The nationwide German inpatient sample of the years 2005-2018 was used for this analysis. Surgical patients were stratified by AF and compared. Logistic regression models were used to investigate the impact of AF on in-hospital outcomes. RESULTS In total, 96,589,627 hospitalizations with surgery were included in the present analysis in Germany (2005-2018). Among these, 6,680,261 were additionally coded with AF (6.9%). In-hospital death rate was substantially higher in surgical patients with AF (6.3%) than without (1.1%). Proportion of surgical patients with AF increased from 4.8% in 2005 to 8.9% in 2018, whereas in-hospital mortality decreased from 7.6% to 5.6%. For further analysis of the year 2014, 7,043,514 hospitalized surgical patients (54.5% females, 31.6% aged ≥0 years) were included in the analysis. Of these, 546,019 patients (7.8%) were diagnosed with AF. Overall, 1.4% of the surgical patients and 5.8% of the surgical patients with AF died in-hospital. Surgical patients with coded AF were in median 20 years older (57.0 [37.0-72.0] vs. 77.0 [72.0-83.0] years, P < 0.001), had more often comorbidities such as heart failure (31.3% vs. 3.8%, P < 0.001). All-cause death (RR 6.14 (95%CI 6.05-6.22), P < 0.001) occurred more often in patients with AF than without. AF was an important predictor for in-hospital death (OR 1.58 [95%CI 1.56-1.61], P < 0.001) independent of age, sex and comorbidities. CONCLUSIONS The proportion of AF increased from 2005 to 2018 in surgical patients. AF was an independent risk factor for in-hospital death in these patients.

Abstract
Pulmonary embolism has extremely varied clinical presentations and can be difficult to diagnose. Clinical decision rules can help determine the probability of pulmonary embolism by assessment of the clinical presentation. After the diagnosis, several prognostic rules can be used to risk-stratify and facilitate outpatient treatment of pulmonary embolism. This review addresses the utility of clinical decision rules, biomarkers in the diagnosis of pulmonary emoblism, high-risk patient phenotypes, the use of this data to make disposition decisions for patients with a diagnosis of PE, and recent shifts in the management of pulmonary embolism in the clinical setting.

Abstract
BACKGROUND Patients with acute pulmonary embolism (PE) often have leg deep vein thrombosis (DVT); sometimes, however, a DVT is not detected (isolated PE, I-PE). We aimed at assessing the proportion of patients with I-PE, and their characteristics and clinical evolution compared to those with DVT with/without PE (DVT/PE). METHODS Among 3573 patients included in the START2-Register for a venous thromboembolic event, 2880 (80.6%) had DVT/PE, the remaining I-PE (19.4%). RESULTS Patients with I-PE were older [(≥75 years, OR 1.4 (95%CI 1.13-1.69)], and more frequently females [OR 1.4 (1.19-1.67)]. Young females (aged ≤ 50 years) with an index event occurring during hormonal contraception (HC), were more prevalent in I-PE [OR 1.96 (1.26-3.03)]. At multivariate analysis, age > 75 years, female sex, heart failure, cancer and use of HC were risk factors significantly associated with I-PE, whereas thrombophilic alterations were associated with DVT/PE. During a follow-up of 4504 years (during anticoagulation), the rate of bleeding events was 1.1% patient/years and 1.0% patient/years in I-PE and DVT/PE, respectively. Venous thromboembolic events were equally prevalent in DVT/PE or I-PE (1.94% vs 0.86%, ns), whereas arterial complications were more prevalent in the latter group (1.01% vs 0.28%, p = 0.008). CONCLUSION I-PE and DVT/PE have important differences. Older age, female sex, heart failure and cancer, were risk factors for I-PE; thrombophilic alterations were associated with DVT/PE. HC use was more frequent in the I-PE group. The prevalence of arterial complications was higher in patients with I-PE. Further studies, specifically designed on this issue, are warranted.

Abstract
BACKGROUND Pulmonary embolism (PE) is a fatal condition, with a subsequent variety of complications. Although rare, the ensuing presentation of atrial fibrillation (AF) secondary to PE is evident in the literature. However, there has been no report of AF with slow ventricular response requiring a pacemaker as a complication of PE. CASE PRESENTATION A 78-year-old obese female presented to the emergency room with new onset dyspnea. Computed tomography pulmonary angiogram revealed bilateral PE. Twenty-four hours later, the patient developed new onset AF with slow ventricular response. Therefore, a single chamber pacemaker was implanted. CONCLUSION PE causing AF with slow ventricular response has not been reported or explained in the literature. The mechanism of this complication is yet to be understood and will require further investigation to explain this newly presented relationship.

Screening duplex ultrasonography in neurosurgery patients does not correlate with a reduction in pulmonary embolism rate or decreased mortality. J Neurosurg 2019; 132:1589-1597. [PMID: 31026839 DOI: 10.3171/2018.12.jns182800] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2018] [Accepted: 12/18/2018] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Deep vein thrombosis (DVT) is a major focus of patient safety indicators and a common cause of morbidity and mortality. Many practices have employed lower-extremity screening ultrasonography in addition to chemoprophylaxis and the use of sequential compression devices in an effort to reduce poor outcomes. However, the role of screening in directly decreasing pulmonary emboli (PEs) and mortality is unclear. At the University of Mississippi Medical Center, a policy change provided the opportunity to compare independent groups: patients treated under a prior paradigm of weekly screening ultrasonography versus a post-policy change group in which weekly surveillance was no longer performed. METHODS A total of 2532 consecutive cases were reviewed, with a 4-month washout period around the time of the policy change. Criteria for inclusion were admission to the neurosurgical service or consultation for ≥ 72 hours and hospitalization for ≥ 72 hours. Patients with a known diagnosis of DVT on admission or previous inferior vena cava (IVC) filter placement were excluded. The primary outcome examined was the rate of PE diagnosis, with secondary outcomes of all-cause mortality at discharge, DVT diagnosis rate, and IVC filter placement rate. A p value < 0.05 was considered significant. RESULTS A total of 485 patients met the criteria for the pre-policy change group and 504 for the post-policy change group. Data are presented as screening (pre-policy change) versus no screening (post-policy change). There was no difference in the PE rate (2% in both groups, p = 0.72) or all-cause mortality at discharge (7% vs 6%, p = 0.49). There were significant differences in the lower-extremity DVT rate (10% vs 3%, p < 0.01) or IVC filter rate (6% vs 2%, p < 0.01). CONCLUSIONS Based on these data, screening Doppler ultrasound examinations, in conjunction with standard-of-practice techniques to prevent thromboembolism, do not appear to confer a benefit to patients. While the screening group had significantly higher rates of DVT diagnosis and IVC filter placement, the screening, additional diagnoses, and subsequent interventions did not appear to improve patient outcomes. Ultimately, this makes DVT screening difficult to justify.

Abstract
BACKGROUND Atherosclerosis is associated with increased cardiovascular mortality. Associations between venous thromboembolism and atherosclerosis were recently reported. We aimed to investigate the impact of symptomatic atherosclerosis on adverse outcomes in patients with pulmonary embolism (PE) and to identify significant differences among patients with PE stratified by symptomatic atherosclerosis. METHODS Patients were selected by screening the nationwide inpatients sample for PE (ICD-code I26) stratified by symptomatic atherosclerosis (composite of coronary artery disease [ICD-code I25], myocardial infarction [ICD-code I21], ischemic stroke [ICD-code I63], and/or atherosclerotic arterial diseases [ICD-code I70]). We compared PE patients with (PE + Athero) and without (PE - Athero) symptomatic atherosclerosis and analysed the impact of symptomatic atherosclerosis on adverse outcomes. RESULTS Overall, 213,995 patients with PE (54.2% females) were included in this analysis. Of these, 30,157 (14.1%) had symptomatic atherosclerosis with age-dependent incline. Deep vein thrombosis or thrombophlebitis (45.1% vs. 36.9%, P < 0.001) was more commonly observed in the PE - Athero group (Odds Ratio (OR) 0.713 [95% CI 0.695-0.731], P < 0.001). In-hospital mortality (12.1% vs. 9.6%, P < 0.001) and adverse in-hospital events (16.8% vs. 12.6%, P < 0.001) were affected by symptomatic atherosclerosis; both in-hospital mortality (OR 1.107 [95% CI 1.061-1.155], P < 0.001) and adverse in-hospital outcomes (OR 1.143 [95%CI 1.102-1.186], P < 0.001) were affected independently of age, gender, comorbidities, and reperfusion treatments. CONCLUSIONS Symptomatic atherosclerosis in patients with PE increased with age and was associated with a poorer outcome. Cardiovascular-atherosclerotic diseases might play a major role in thrombus formation in isolated PE.

Abstract
INTRODUCTION This study evaluated the incidence of symptomatic pulmonary embolism (PE), subsequent mortality, risk factors, and the effects of pharmacological thromboprophylactic intervention following hip fracture surgery in Taiwan. MATERIALS AND METHODS A nationwide study was conducted from February 2004 to September 2013. Hip fracture patients were placed into two groups: without symptomatic PE (control group) and with symptomatic PE (PE group). We analyzed the incidence of and risk factors for symptomatic PE, post-operative mortality rate, and effects of pharmacological thromboprophylactic intervention. RESULTS We identified 165,748 hip fracture patients. The 3-month cumulative incidence of post-operative symptomatic PE was 0.24% (n = 392). The cumulative 1-, 3-, and 6-month mortality rates were significantly higher in the PE group (16.1%, 23.0%, and 28.6%, respectively) than in the controls (3.3%, 6.7%, and 10.2%, respectively). Increased risk of post-operative symptomatic PE was associated with prior history of PE (adjusted odds ratio [OR], 40.00; 95% CI, 24.75-64.67; P < 0.001), female sex (adjusted OR, 1.33; 95% CI, 1.07-1.65; P = 0.009), older age (>75 years) (adjusted OR, 1.51; 95% CI, 1.20-1.91; P < 0.001), and hemiarthroplasty (adjusted OR, 1.23; 95% CI, 1.01-1.51; P < 0.043). Pharmacological thromboprophylaxis significantly reduced the incidence of post-operative PE (adjusted hazard ratio, 4.54; 95% CI, 2.08-9.88; P < 0.001). CONCLUSIONS The incidence of symptomatic PE after hip fracture surgery was not low in Asian patients, and PE significantly decreased patient survival rates. Some groups were at higher risk for PE; in these instances, thromboprophylaxis, prompt diagnosis, and subsequent intervention are advised.

Abstract
Essentials Atrial fibrillation (AF) may increase risk of venous thromboembolism (VTE), and vice versa. Bidirectionality was assessed prospectively via data from 15 129 black and white individuals. AF was associated with greater risk of developing VTE, and VTE with greater risk of AF. Associations were strongest among blacks and in the first 6 months after initial diagnosis. SUMMARY Background Atrial fibrillation (AF) and venous thromboembolism (VTE) frequently co-occur. These conditions have shared risk factors and are accompanied by coagulation abnormalities. Furthermore, mechanistic pathways may directly link the disorders. Objectives To test the hypothesis that individuals with incident AF are at greater risk of developing VTE, and those with VTE are at elevated risk of AF. We also tested whether associations were stronger in the first 6 months after the initial diagnosis, and explored race differences. Patients/Methods A total of 15 129 ARIC study participants (45-64 years, 55% female, 26% Black) were followed from 1987 to 2011 for incident AF and VTE (median follow-up 19.8 years). Multivariable-adjusted Cox regression was used, with AF and VTE modeled as time-dependent exposures. Results Incident AF was associated with greater risk of subsequent incident VTE (hazard ratio [95% CI], 1.71 [1.32-2.22]); the association was stronger in Black people (2.30 [1.48-3.58]) and during the first 6 months after AF diagnosis (5.08 [3.08-8.38]). Similarly, incident VTE was associated with increased risk of incident AF (1.73 [1.34-2.24]), especially in Black people (2.40 [1.55-3.74]) and in the first 6 months after VTE diagnosis (4.50 [2.61-7.77]). Conclusions The occurrence of AF was associated with increased risk of incident VTE, and occurrence of VTE was associated with greater risk of incident AF. Associations were particularly strong among Black people and during the first 6 months after the initial diagnosis, although they remained elevated even after 6 months. These findings highlight patient populations that may be at increased risk of AF and VTE, and perhaps should be targeted with preventive strategies.

Abstract
The relationship and clinical implications of atrial fibrillation (AF) in acute pulmonary embolism (PE) are poorly investigated. We aimed to analyze clinical characteristics and prognosis in PE patients with paroxysmal AF episode. Methods. From the 391 patients with PE 31 subjects with paroxysmal AF were selected. This group was compared with patients with PE and sinus rhythm (SR) and 32 patients with PE and permanent AF. Results. Paroxysmal AF patients were the oldest. Concomitant DVT varies between groups: paroxysmal AF 32.3%, SR 49.5%, and permanent AF 28.1% (p = 0.02). The stroke history frequency was 4.6% SR, 12.9% paroxysmal AF, and 21.9% permanent AF (p < 0.001). Paroxysmal AF comparing to permanent AF and SR individuals had higher estimated SPAP (56 versus 48 versus 47 mmHg, p = 0.01) and shorter ACT (58 versus 65 versus 70 ms, p = 0.04). Patients with AF were more often classified into high-risk group according to revised Geneva score and sPESI than SR patients. In-hospital mortality was lower in SR (5%) and paroxysmal AF (6.5%) compared to permanent AF group (25%) (p < 0.001). Conclusions. Patients with PE-associated paroxysmal AF constitute a separate population. More severe impairment of the parameters reflecting RV afterload may indicate relation between PE severity and paroxysmal AF episode. Paroxysmal AF has no impact on short-term mortality.

Abstract
AIM We aimed to study a single nucleotide polymorphism (SNP), rs2106261, in the transcription factor gene, ZFHX3, in atrial fibrillation (AF) and other related phenotypes by phenome scanning in a Japanese population. METHOD We retrieved consecutive autopsy data (n=2433, mean age=80 years) from the Japanese SNP database for geriatric diseases (JG-SNP). Clinical data, including an AF diagnosis, were collected from medical charts. Genotyping was performed with the DNA chip method. We also analyzed 42 pathological and 26 clinical phenotypes, including cerebral infarctions (CIs) and lung thromboembolisms (LTs), diagnosed by macroscopic inspection during the autopsy. RESULT Among the 2433 patients with available data, 18.6% had AF, 29.4% had CI, and 4.9% had LT phenotypes. The A allele of the rs2106261 SNP was significantly associated with AF, after adjusting for age, sex, diabetes, hypertension, and smoking (AA+AG/GG, OR=1.51, 95%CI: 1.16-1.97, p=0.002). In the entire cohort, CI was not associated with rs2106261 (p=0.14). However, among patients under 80 years old, rs2106261 was significantly associated with CI (AA+AG/GG, OR=1.57, 95%CI: 1.09-2.26, p=0.01). LT was also associated with rs2106261 (AA+AG/GG, OR=1.99, 95%CI: 1.31-3.01, p=0.001). Associations between rs2106261 and CI and LT remained positive after adjusting for the presence of AF, which indicated that this SNP variant might serve as an independent risk marker. CONCLUSION We showed that the ZFHX3 polymorphism, rs2106261 (A allele), was a risk marker for AF and AF-related phenotypes. The roles of this variant in the development of AF and its related phenotypes warrant further investigation.

Abstract
Background Open esophagectomy (OE) is associated with significant morbidity and mortality. Minimally invasive oesophagectomy (MIO) reduces complications in resectable esophageal cancer. The aim of this study is to explore the superiority of MIO in reducing complications and in-hospital mortality than OE. Methods MEDLINE, Embase, Science Citation Index, Wanfang, and Wiley Online Library were thoroughly searched. Odds ratio (OR)/weighted mean difference (WMD) with a 95% confidence interval (CI) was used to assess the strength of association. Results Fifty-seven studies containing 15,790 cases of resectable esophageal cancer were included. MIO had less intraoperative blood loss, short hospital stay, and high operative time (P < 0.05) than OE. MIO also had reduced incidence of total complications; (OR = 0.700, 95% CI = 0.626 ~ 0.781, PV < 0.05), pulmonary complications (OR = 0.527, 95% CI = 0431 ~ 0.645, PV < 0.05), cardiovascular complications (OR = 0.770, 95% CI = 0.681 ~ 0.872, PV < 0.05), and surgical technology related (STR) complications (OR = 0.639, 95% CI = 0.522 ~ 0.781, PV < 0.05), as well as lower in-hospital mortality (OR = 0.668, 95% CI = 0.539 ~ 0.827, PV < 0.05). However, the number of harvested lymph nodes, intensive care unit (ICU) stay, gastrointestinal complications, anastomotic leak (AL), and recurrent laryngeal nerve palsy (RLNP) had no significant difference. Conclusions MIO is superior to OE in terms of perioperative complications and in-hospital mortality.

Abstract
Background: Pulmonary embolism (PE) is a life-threatening event with a broad presentation spectrum ranging from asymptomatic cases to sudden cardiac arrest. It is unclear if right atrial emboli cause PE in patients with atrial fibrillation (AF) or if mild PE itself increases right cardiac pressure provoking AF. Objective: To determine the incidence and predictors of asymptomatic PE in patients undergoing AF ablation. Method and Results: Patients (n = 93) were screened and those with previous or current symptomatic PE or venous thromboembolism, pulmonary hypertension, increased right heart pressures detected on echocardiography, a history of stroke, transient ischemic attack, coagulopathy or cancer and inappropriate contrast for the evaluation of pulmonary arterial tree were excluded. The remaining AF patients (n = 71) underwent guided ablation controlled with 3-dimensional, left atrial and pulmonary venous computed tomography. The asymptomatic PE was defined by using the modified Miller score by 2 independent assessors in 6 patients. Univariate logistic regression showed that age (OR: 1.094, 95% CI 1.007-1.188, p = 0.033), diabetes (OR: 12.000, 95% CI 1.902-75.716, p = 0.008), CHA2DS2-VASc score (OR: 2.800, 95% CI 1.304-6.013, p = 0.008), and pulmonary artery diameter (OR: 1.221, 95% CI 1.033-1.444, p = 0.019) were significantly associated with PE. However, multivariate analysis revealed that the CHA2DS2-VASc score (p = 0.047) remained the exclusive significant predictor for asymptomatic PE. Conclusion: The incidence of random asymptomatic PE in AF patients is high (>8%). The CHA2DS2-VASc score can predict silent PE. Since patients with a high CHA2DS2-VASc score are already anticoagulated, our results do not change clinical practice but are noteworthy in terms of the cause-effect relationship between AF and PE.

Acad Emerg Med 2015; 22:1127-37. [PMID: 26394330 DOI: 10.1111/acem.12769] [Citation(s) in RCA: 65] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2015] [Revised: 05/28/2015] [Accepted: 06/02/2015] [Indexed: 01/09/2023]
Abstract
OBJECTIVES Treatment guidelines for acute pulmonary embolism (PE) recommend risk stratifying patients to assess PE severity, as those at higher risk should be considered for therapy in addition to standard anticoagulation to prevent right ventricular (RV) failure, which can cause hemodynamic collapse. The hypothesis was that 12-lead electrocardiography (ECG) can aid in this determination. The objective of this study was to measure the prognostic value of specific ECG findings (the Daniel score, which includes heart rate > 100 beats/min, presence of the S1Q3T3 pattern, incomplete and complete right bundle branch block [RBBB], and T-wave inversion in leads V1-V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute pulmonary hypertension), in patients with acute PE. METHODS Studies were identified by a structured search of MEDLINE, PubMed, EMBASE, the Cochrane library, Google Scholar, Scopus, and bibliographies in October 2014. Case reports, non-English papers, and those that lacked either patient outcomes or ECG findings were excluded. Papers with evidence of a predefined reference standard for PE and the results of 12-lead ECG, stratified by outcome (hemodynamic collapse, defined as circulatory shock requiring vasopressors or mechanical ventilation, or in hospital or death within 30 days) were included. Papers were assessed for selection and publication bias. The authors also assessed heterogeneity (I(2) ) and calculated the odds ratios (OR) for each ECG sign from the random effects model if I(2) > 24% and fixed effects if I(2) < 25%. Funnel plots were used to examine for publication bias. RESULTS Forty-five full-length studies of 8,209 patients were analyzed. The most frequent ECG signs found in patients with acute PE were tachycardia (38%), T-wave inversion in lead V1 (38%), and ST elevation in lead aVR (36%). Ten studies with 3,007 patients were included for full analysis. Six ECG findings (heart rate > 100 beats/min, S1Q3T3, complete RBBB, inverted T waves in V1-V4, ST elevation in aVR, and atrial fibrillation) had likelihood and ORs with lower-limit 95% confidence intervals above unity, suggesting them to be significant predictors of hemodynamic collapse and 30-day mortality. OR data showed no evidence of publication bias, but the proportions of patients with hemodynamic collapse or death and S1Q3T3 and RBBB tended to be higher in smaller studies. Patients who were outcome-negative had a significantly lower mean ± SD Daniel score (2.6 ± 1.5) than patients with hemodynamic collapse (5.9 ± 3.9; p = 0.039, ANOVA with Dunnett's post hoc), but not patients with all-cause 30-day mortality (4.9 ± 3.3; p = 0.12). CONCLUSIONS This systematic review and meta-analysis revealed 10 studies, including 3,007 patients with acute PE, that demonstrate that six findings of RV strain on 12-lead ECG (heart rate > 100 beats/min, S1Q3T3, complete RBBB, inverted T waves in V1-V4, ST elevation in aVR, and atrial fibrillation) are associated with increased risk of circulatory shock and death.

History of deep vein thrombosis is a discriminator for concomitant atrial fibrillation in pulmonary embolism. Thromb Res 2015; 136:899-906. [PMID: 26376038 DOI: 10.1016/j.thromres.2015.08.024] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2015] [Revised: 08/22/2015] [Accepted: 08/29/2015] [Indexed: 01/10/2023]
Abstract
BACKGROUND Pulmonary embolism (PE) is the consequence of deep vein thrombosis (DVT) in 70% of all cases. Although, PE and DVT are commonly related to risk factors of Virchow's triad, both entities are linked to cardiovascular risk factors, but risk factors seem differently important in both entities. OBJECTIVES We aimed to investigate clinical profile and outcome of patients with PE history stratified by concomitant DVT. PATIENTS/METHODS Data from the observational multi-center thrombEVAL-study were analyzed. RESULTS The sample (N=2,318) comprised 295 PE patients, of whom 69.2% (N=204) had DVT. Individuals without DVT were older and had higher prevalence of concomitant atrial fibrillation (AF), chronic lung diseases, coronary artery disease, heart failure and hypertension. Multivariable regression revealed an independent association of AF (Odds Ratio (OR) 3.17, 95% CI 1.63-6.18, P<0.001) and coronary artery disease (OR 2.31, 95% CI 1.15-4.66, P=0.019) with PE without DVT. There was higher frequency of permanent AF in individuals without DVT, whereas paroxysmal AF was more prevalent in individuals with DVT. All AF subtypes were independently associated with PE without DVT with increasing ORs from paroxysmal to permanent AF. PE patients with and without DVT did not differ in survival (P=0.32) and cost-relevant clinical outcome (P=0.26) during follow-up. AF in PE patients was associated with cost-relevant clinical outcome (Hazard Ratio (HR) 1.78, 95% CI 1.03-3.09, P=0.040), but no significant difference in survival (HR 0.93, 95% CI 0.35-2.50, P=0.88) was observed. CONCLUSIONS History of DVT is a significant discriminator for clinical profile of PE patients. Individuals without DVT had more often cardiac and pulmonary disease with strongest association with AF. Data advocate a potential link between AF and PE. CLINICAL TRIAL REGISTRATION URL: http://www.clinicaltrials.gov, Unique identifier NCT01809015.

Abstract
Background Compared with open oesophagectomy (OE), minimally invasive oesophagectomy (MIO) proves to have benefits in reducing the risk of pulmonary complications for patients with resectable oesophageal cancer. However, it is unknown whether MIO has superiority in reducing the occurrence of in-hospital mortality (IHM). Objective The objective of this meta-analysis was to explore the effect of MIO vs. OE on the occurrence of in-hospital mortality (IHM). Data Sources Sources such as Medline (through December 31, 2014), Embase (through December 31, 2014), Wiley Online Library (through December 31, 2014), and the Cochrane Library (through December 31, 2014) were searched. Study Selection Data of randomized and non-randomized clinical trials related to MIO versus OE were included. Interventions Eligible studies were those that reported patients who underwent MIO procedure. The control group included patients undergoing conventional OE. Study Appraisal and Synthesis Methods Fixed or random -effects models were used to calculate summary odds ratios (ORs) or relative risks (RRs) for quantification of associations. Heterogeneity among studies was evaluated by using Cochran’s Q and I2 statistics. Results A total of 48 studies involving 14,311 cases of resectable oesophageal cancer were included in the meta-analysis. Compared to patients undergoing OE, patients undergoing MIO had statistically reduced occurrence of IHM (OR=0.69, 95%CI =0.55 -0.86). Patients undergoing MIO also had significantly reduced incidence of pulmonary complications (PCs) (RR=0.73, 95%CI = 0.63-0.86), pulmonary embolism (PE) (OR=0.71, 95%CI= 0.51-0.99) and arrhythmia (OR=0.79, 95%CI = 0.68-0.92). Non-significant reductions were observed among the included studies in the occurrence of anastomotic leak (AL) (OR=0.93, 95%CI =0.78-1.11), or Gastric Tip Necrosis (GTN) (OR=0.89, 95%CI =0.54-1.49). Limitation Most of the included studies were non-randomized case-control studies, with a diversity of study designs, demographics of participants and surgical intervention. Conclusions Minimally invasive oesophagectomy (MIO) has superiority over open oesophagectomy (OE) in terms of the occurrence of in-hospital mortality (IHM) and should be the first-choice surgical procedure in esophageal surgery.

Abstract
Atrial fibrillation (AF) can induce a hypercoagulable state in both the left and right atria. Thrombus in the right side of the heart (RHT) may lead to acute pulmonary embolism (APE). The aim of the study was to determine the prevalence of RHT and AF and to assess their impact on outcomes in patients with APE. The retrospective cohort included 1,006 patients (598 female), with a mean age of 66 ± 15 years. The primary end point was all-cause mortality. The secondary end point was incidence of complications (death, cardiogenic shock, cardiac arrest, vasopressor/inotrope treatment, or ventilatory support). Atrial fibrillation was detected in 231 patients (24%). RHT was observed in 50 patients (5%). The combination of AF and RHT was observed in 16 patients (2%). The overall mortality rate was significantly higher in patients with RHT compared with those without (32% vs 14%, respectively, odds ratio [OR] 3.0, 95% confidence interval [CI] 1.6 to 5.6, p = 0.001). The rate of complications was significantly higher in patients with RHT in comparison to those without (40% vs 22%, respectively, OR 2.4, 95% CI 1.3 to 4.4, p = 0.004). The mortality rate in patients with both AF and RHT was significantly higher in comparison to those with AF but without RHT (50% vs 20%, respectively, OR 3.86, 95% CI 1.3 to 11.2, p = 0.01). In multivariate analysis, RHT (p = 0.03) was an independent predictor of death. In conclusion, AF is a frequent co-morbidity in patients with APE, and the presence of RHT is not uncommon. Among patients with APE, the presence of RHT increases the mortality approximately threefold regardless of the presence of known AF.

Abstract
Whether atrial fibrillation (AF) is associated with an increased risk of venous thromboembolism (VTE) remains controversial. From Longitudinal Health Insurance Database 2000 (LHID2000), we identified 11,458 patients newly diagnosed with AF. The comparison group comprised 45,637 patients without AF. Both cohorts were followed up to measure the incidence of deep-vein thrombosis (DVT) and pulmonary embolism (PE). Univariable and multivariable competing-risks regression model and Kaplan-Meier analyses with the use of Aelon-Johansen estimator were used to measure the differences of cumulative incidences of DVT and PE, respectively. The overall incidence rates (per 1,000 person-years) of DVT and PE between the AF group and non-AF groups were 2.69 vs 1.12 (crude hazard ratio [HR]= 1.92; 95 % confidence interval [CI] = 1.54-2.39), 1.55 vs 0.46 (crude HR = 2.68; 95 % CI = 1.97-3.64), respectively. The baseline demographics indicated that the members of the AF group demonstrated a significantly older age and higher proportions of comorbidities than non-AF group. After adjusting for age, sex, and comorbidities, the risks of DVT and PE remained significantly elevated in the AF group compared with the non-AF group (adjusted HR = 1.74; 95 %CI = 1.36-2.24, adjusted HR = 2.18; 95 %CI = 1.51-3.15, respectively). The Kaplan-Meier curve with the use of Aelon-Johansen estimator indicated that the cumulative incidences of DVT and PE were both more significantly elevated in the AF group than in the non-AF group after a long-term follow-up period (p<0.01). In conclusion, the presence of AF is associated with increased risk of VTE after a long-term follow-up period.

Abstract
BACKGROUND Pulmonary embolism (PE) may trigger atrial fibrillation through increased right atrial pressure and subsequent atrial strain, but the degree of evidence is low. In this study, we wanted to investigate the impact of incident venous thromboembolism (VTE) on future risk of atrial fibrillation in a prospective population-based study. METHODS AND RESULTS The study included 29 974 subjects recruited from the Tromsø study (1994-1995, 2001-2002, 2007-2008). Incident VTE and atrial fibrillation events were registered from date of enrolment to end of follow-up, December 31, 2010. Cox proportional hazard regression models using age as time-scale and VTE as a time-dependent variable were used to estimate crude and multivariable hazard ratios (HRs) for atrial fibrillation with 95% confidence intervals (CIs). During 16 years of follow up, 540 (1.8%) subjects had an incident VTE event, and 1662 (5.54%) were diagnosed with atrial fibrillation. Among those with VTE, 50 (9.3%) developed subsequent atrial fibrillation. Patients with VTE had 63% higher risk of atrial fibrillation compared to subjects without VTE (multivariable-adjusted HR: 1.63, 95% CI: 1.22 to 2.17). The risk of atrial fibrillation was particularly high during the first 6 months after the VTE event (HR 4.00, 95% CI: 2.21 to 7.25) and among those with PE (HR 1.78, 95% CI: 1.13 to 2.80). CONCLUSIONS We found that incident VTE was associated with future risk of atrial fibrillation. Our findings support the hypothesis that PE may lead to cardiac dysfunctions that, in turn, could trigger atrial fibrillation.

Abstract
BACKGROUND The incidence of inpatient pulmonary embolism in patients who have elective primary hip and knee arthroplasty in the United States is unknown. Prior studies have included patients with cancer, trauma, or revisions. The goal of this study was to determine the incidence and risks of inpatient pulmonary embolism after elective arthroplasty by type of procedure. METHODS We used the 1998 to 2009 Healthcare Cost and Utilization Project Nationwide Inpatient Sample for this retrospective cohort study. Patients who were sixty years of age or older and underwent elective primary total hip or knee arthroplasty were included. The study variable was the type of arthroplasty: total hip, total knee, or two joints. Inpatient pulmonary embolism was the primary outcome; mortality was secondary. Logistic regression determined the adjusted odds ratios of inpatient pulmonary embolism by procedure, adjusting for age, sex, Charlson Comorbidity Index, atrial fibrillation, and surgical indication. RESULTS Records represented 5,044,403 hospital discharges after primary total hip or knee arthroplasty. Total knee arthroplasty comprised 66% of the admissions. Less than 5% of patients had two joint procedures. The overall incidence of pulmonary embolism was 0.358% (95% confidence interval [CI], 0.338, 0.378). The incidence of pulmonary embolism differed by procedure and was highest among patients who had two-joint arthroplasty (0.777%; 95% CI, 0.677, 0.876), was lowest in recipients of total hip arthroplasty (0.201%; 95% CI, 0.179, 0.223), and was intermediate in patients who had total knee arthroplasty (0.400%; 95% CI, 0.377, 0.423). The adjusted odds ratios of pulmonary embolism in patients who had two joint procedures were 3.89 times higher than among patients who had total hip arthroplasty, controlling for other factors. CONCLUSIONS Elective total knee arthroplasty is associated with a higher incidence and odds of inpatient pulmonary embolism than is total hip arthroplasty; multiple procedures pose the highest risk for pulmonary embolism and associated mortality.

Abstract
AIMS Although it is accepted that atrial fibrillation (AF) may be both the contributing factor and the consequence of pulmonary embolism (PE), data on the prognostic role of AF in patients with acute venous thromboembolism are scarce. Our aim was to study whether AF had a prognostic role in patients with acute PE. METHODS Retrospective cohort study involving 270 patients admitted for acute PE. Collected data: past medical history, analytic/gasometric parameters, admission ECG and echocardiogram, thoracic CT angiography. Patients followed for 6 months. An analysis was performed in order to clarify whether history of AF, irrespective of its timing, helps predict intrahospital, 1-month and 6-month all-cause mortality. RESULTS Patients with history of AF, irrespective of its timing (n=57, 21.4%), had higher intrahospital (22.8% vs 13.1%, p=0.052, OR 2.07, 95% CI 0.98 to 4.35), 1-month (35.1% vs 16.9%, p=0.001, OR 3.16, 95% CI 1.61 to 6.21) and 6-month (45.6% vs 17.4%, p<0.001, OR 4.67, 95% CI 2.37 to 9.21) death rates. The prognostic power of AF was independent of age, NT-proBNP values, renal function and admission blood pressure and heart rate and additive to mortality prediction ability of simplified PESI (AF: p=0.021, OR 2.31, CI 95% 1.13 to 4.69; simplified PESI: p=0.002, OR 1.47, CI 95% 1.15 to 1.89). The presence of AF at admission added prognostic value to previous history of AF in terms of 1-month and 6-month all-cause mortality prediction, although it did not increase risk for intrahospital mortality. CONCLUSIONS The presence of AF, irrespective of its timing, may independently predict mortality in patients with acute PE. These data should be tested and validated in prospective studies using larger cohorts.
