Objectives: This study aimed to compare the short-term and long-term follow-up outcomes of catheter-directed thrombolysis (CDT) with those of pulmonary artery embolectomy (PAE) for patients with acute pulmonary embolism (PE) included in a nationwide cohort. Background: Data allowing direct comparisons between CDT and PAE are lacking in the literature, and the optimal management of high-risk and intermediate-risk PE is still debated. Methods: A retrospective cohort study was conducted with data for 2001 through 2013 collected from the Taiwan National Health Insurance Research Database (NHIRD). Patients who were first admitted for PE and treated with either CDT or PAE were included and compared. In-hospital outcomes included in-hospital death and safety (bleeding and cardiac arrhythmias) outcomes. Follow-up outcomes included all-cause mortality and recurrent PE during the 1- and 2-year follow-up periods and through the last follow-up. Inverse probability of treatment weighting (IPTW) based on the propensity score was used to minimize possible selection bias, including indices for multimorbidity such as the Charlson’s Comorbidity Index (CCI) and HAS-BLED scores. Results: A total of 389 patients treated between January 1, 2001, and December 31, 2013, were identified; 169 underwent CDT and 220 underwent PAE. After IPTW, there were no significant differences in in-hospital mortality (18.2% vs 21.3%; odds ratio 1.07, 95% confidence interval [CI]: 0.70–1.62) or the incidence of safety outcomes between the CDT and PAE groups. The risks of all-cause mortality (30% vs 29.5%; hazard ratio 1.16, 95% CI: 0.89–1.53), recurrent PE (7.2% vs 8.7%; subdistribution hazard ratio [SHR] 0.68, 95% CI: 0.39–1.21) and new-onset pulmonary hypertension (SHR 0.25, 95% CI: 0.05–1.32) were also not significantly different between the CDT and PAE groups at 2 years of follow-up. Subgroup analysis indicated that PAE may be associated with a more favorable 2-year mortality in patients <65 years old, patients with CCI scores of <3, patients with HAS-BLED scores of 1 to 2, and patients without cardiogenic shock (all P for interaction <.05). Conclusions: In patients with PE who required reperfusion therapy, CDT and PAE resulted in similar in-hospital and long-term all-cause mortality rates and long-term rates of recurrent PE. Bleeding risks were also comparable in the 2 groups.

Background This study compared the efficacy and safety between catheter‐directed thrombolysis (CDT) and systemic thrombolysis for patients with acute pulmonary embolism (PE) with midterm follow‐up. Methods and Results We conducted a prospective open cohort study by using data from the Taiwan National Health Insurance Research Database for 2001 to 2013. Patients who were first admitted for PE and were treated by either systemic thrombolysis or CDT were included and compared. Inverse probability of treatment weighting, based on the propensity score, was used to mitigate possible selection bias. A total of 145 CDT‐treated and 1158 systemic thrombolysis–treated patients with PE were included. The in‐hospital mortality rate was significantly lower in the CDT group (12.7% versus 21.4%; odds ratio, 0.49; 95% CI, 0.36–0.67) after inverse probability of treatment weighting. No significant differences between the groups were observed for the safety (bleeding) outcomes. In patients who survived the index PE admission, the 1‐year all‐cause mortality rate was significantly lower in the CDT group after inverse probability of treatment weighting (12.2% versus 13.2%; hazard ratio [HR], 0.73; 95% CI, 0.56–0.94). Treatment with CDT was also associated with lower risks of recurrent PE (9.3% versus 17.5%; subdistribution HR, 0.52; 95% CI, 0.41–0.66). The difference remained through the last follow‐up. Conclusions Among patients with PE requiring reperfusion therapy, those accepting CDT had lower all‐cause mortality and recurrent PE over both short‐term and midterm follow‐up periods than those receiving systemic thrombolysis. The bleeding risk was similar for both groups. These findings should be cautiously validated in future randomized trials.

We assessed the efficacy of thrombolysis in avoiding long-term complications. Notes of patients thrombolysed for PE in the 2-year period were reviewed. The initial CTPA and echocardiogram results before thrombolysis were compared to the results of follow up imaging repeated after 6 months. Twenty-two patients were thrombolysed for PE. 14 patients had sub-massive PE and 8 patients had massive PE. The right ventricle (RV) was dilated on pre-thrombolysis echocardiogram in 16 patients. On follow up echocardiography all patients with massive PE (6 studies) had a normal RV size, with pulmonary artery pressures (PAP) of 29mmHg. Follow up echocardiography of patients with submassive PE (13 studies) showed 11 patients with a normal RV, with PAP of 28 mmHg.

Abstract Background We aimed to test if impaired oxygenation or major hemodynamic instability at the time of emergency intensive care transport between hospitals are predictors of long-term mortality.Methods From a regional hospital intensive care transport research database, the study cohort was identified as those emergency intensive care cases transported in fixed-wing air ambulance from outlying hospitals to a regional tertiary care center during 2000–2016 for adults (16 years old or older). Impaired oxygenation was defined as oxyhemoglobin % - inspired oxygen fraction ratio (S/F ratio) < 100. Major hemodynamic instability was defined as need for treatment with noradrenaline infusion to sustain mean arterial pressure (MAP) at or above 60 mmHg or having a mean MAP < 60. All-cause mortality at 3 months after transport was the primary outcome, and secondary outcomes were all-cause mortality at 6 and 12 months. Multivariate cumulative survival and hazard analysis was performed for intervals 3, 6 and 12 months.Results There were 2142 patients included in the analysis. The S/F ratio < 100 was associated with increased mortality risk compared to S/F > 300 at all time-points, with hazard ratio (HR) 2.9 (1.9–4.4 95% CI, p < 0.001) at 12 months. Major hemodynamic instability during ICU transport was associated with increased HR of all-cause mortality up to one year with hazard ratio 1.9 (1.5–2.5, p < 0.001).Conclusion Major impairment of oxygenation and/or major hemodynamic instability at the time of ICU transport to get to urgent tertiary intervention is strongly associated with reduced survival at least up to one year after the transport, in this cohort. These findings support the conclusion that these conditions are markers for many fold increase in risk for death notable already at 3 months after transport for patients with these conditions. How much this risk is modifiable is not assessable in this analysis.

Abstract Introduction Prognosis in pulmonary hypertension (PH) is strictly linked to right ventricle (RV) failure, which results from uncoupling between RV and the superimposed pressure load; in first phases, coupling between these two actors still be preserved, at the price of augmented right ventricle wall tension (RVWT). Purpose We sought to describe how to estimate RVWT with echocardiography, how it correlates with RV hemodynamics and if it may predict prognosis. Methods A total of 190 patients without overt RV failure, with suspected pulmonary hypertension (PH) to a previous echocardiography, underwent to right heart catheterization (RHC) and nearly-simultaneous echocardiography. We estimated RVWT according to Laplace law (RV length × tricuspid regurgitation peak gradient [TRPG]), in order to predict initial RV stress, and was correlated with RV hemodynamic profile; its potential prognostic impact was tested along with canonical RV function parameters. Results In patients enrolled in our study, RVWT correlated significantly with invasive estimation of right ventricle end diastolic pressure (R 0.343, p<0.001); a significant relationship between RVWT and several hemodynamic variables was observed (mean pulmonary artery pressure, pulmonary artery compliance, transpulmonary gradient, pulmonary vascular resistance, RV telediastolic pressure, right atrial pressure, RV stroke work index; all p<0.001). At a mean follow up of five years and three months, only RVWT predicted all-cause mortality (p 0.036), while TAPSE, TAPSE/TRPG, RV fractional area change and RV S' wave did not. Correlation: RWVT and RV hemodynamic Hemodynamic variable R R2 p value Mean pulmonary artery pressure 0.742 0.550 <0.001 RV differential pressure 0.794 0.630 <0.001 Pulmonary artery pulsatory pressure 0.740 0.547 <0.001 Mean right atrium pressure 0.326 0.106 <0.001 Cardiac index/right atrial pressure 0.209 0.044 0.012 RV stroke work index 0.588 0.346 <0.001 Pulmonary artery compliance 0.449 0.202 <0.001 Pulmonary vascular resistance 0.531 0.282 <0.001 Prognosis: different RV variables Discussion We identified a novel bedside echocardiographic predictor of altered RV hemodynamic, which results precociously altered in patients without overt RV failure, and able to predict all cause mortality at a long term follow up. Further studies are needed to confirm its role in PH patients.

Acute Pe

Limited data exist that comprehensively describe the practical management, in-hospital outcomes, healthcare resource utilization, and rates of post-hospital readmission among patients with submassive and massive pulmonary embolism (PE). Consecutive discharges for acute PE were identified from a single health system over 3 years. Records were audited to confirm presence of acute PE, patient characteristics, disease severity, medical treatment, and PE-related invasive therapies. Rates of in-hospital major bleeding and death, hospital length of stay (LOS), direct costs, and hospital readmission are reported. From January 2016 to December 2018, 371 patients were hospitalized for acute massive or submassive PE. In-hospital major bleeding (12.1%) was common, despite low utilization of systemic thrombolysis (1.8%) or catheter-directed thrombolysis (3.0%). In-hospital death was 10-fold higher among massive PE compared to submassive PE (36.6% vs 3.3%, p < 0.001). Massive PE was more common during hospitalizations not primarily related to venous thromboembolism, including hospitalizations primarily for sepsis or infection (26.8% vs 8.2%, p = 0.001). Overall, the median LOS was 6.0 days (IQR, 3.0–11.0) and the median standardized direct cost of admissions was $10,032 (IQR, $4467–$20,330). Rates of all-cause readmission were relatively high throughout late follow-up but did not differ between PE subgroups. Despite low utilization of thrombolysis, in-hospital bleeding remains a common adverse event during hospitalizations for acute PE. Although massive PE is associated with high risk for in-hospital bleeding and death, those successfully discharged after a massive PE demonstrate similar rates of readmission compared to submassive PE into late follow-up.

AbstractPrevious studies on the adverse events of acute pulmonary embolism (APE) were mostly limited to single marker, and short follow-up duration, from hospitalization to up to 30 days. We aimed to predict the long-term prognosis of patients with APE by joint assessment of D-dimer, N-Terminal Pro-Brain Natriuretic Peptide (NT-ProBNP), and troponin I (cTnI). Newly diagnosed patients of APE from January 2011 to December 2015 were recruited from three hospitals. Medical information of the patients was collected retrospectively by reviewing medical records. Adverse events (APE recurrence and all-cause mortality) of all enrolled patients were followed up via telephone. D-dimer > 0.50 mg/L, NT-ProBNP > 500 pg/mL, and cTnI > 0.40 ng/mL were defined as the abnormal. Kaplan–Meier curve was used to compare the cumulative survival rate between patients with different numbers of abnormal markers. Cox proportional hazard regression model was used to further test the association between numbers of abnormal markers and long-term prognosis of patients with APE after adjusting for potential confounding. During follow-up, APE recurrence and all-cause mortality happened in 78 (30.1%) patients. The proportion of APE recurrence and death in one abnormal marker, two abnormal markers, and three abnormal markers groups were 7.69%, 28.21%, and 64.10% respectively. Patients with three abnormal markers had the lowest survival rate than those with one or two abnormal markers (Log-rank test, P < 0.001). After adjustment, patients with two or three abnormal markers had a significantly higher risk of the total adverse event compared to those with one abnormal marker. The hazard ratios (95% confidence interval) were 6.27 (3.24, 12.12) and 10.7 (4.1, 28.0), respectively. Separate analyses for APE recurrence and all-cause death found similar results. A joint test of abnormal D-dimer, NT-ProBNP, and cTnI in APE patients could better predict the long-term risk of APE recurrence and all-cause mortality.

Guidelines for management of normotensive patients with acute pulmonary embolism (PE) emphasize further risk stratification on the basis of right ventricular (RV) size and biomarkers of RV injury or strain; however, the prognostic importance of these factors on long-term mortality is not known. We performed a retrospective cohort study of subjects diagnosed with acute PE from 2010 to 2015 at a tertiary care academic medical center. The severity of initial PE presentation was categorized into three groups: massive, submassive, and low-risk PE. The primary endpoint of all-cause mortality was ascertained using the Centers for Disease Control National Death Index (CDC NDI). A total of 183 subjects were studied and their median follow-up was 4.1 years. The median age was 65 years. The 30-day mortality rate was 7.7% and the overall mortality rate through the end of follow-up was 40.4%. The overall mortality rates for massive, submassive, and low-risk PE were 71.4%, 44.5%, and 28.1%, respectively ( p < 0.001). Landmark analysis using a 30-day cutpoint demonstrated that subjects presenting with submassive PE compared with low-risk PE had increased mortality during both the short- and the long-term periods. The most frequent causes of death were malignancy, cardiac disease, respiratory disease, and PE. Independent predictors of all-cause mortality were cancer at baseline, age, white blood cell count, diabetes mellitus, liver disease, female sex, and initial presentation with massive PE. In conclusion, the diagnosis of acute PE was associated with substantial long-term mortality. The severity of initial PE presentation was associated with both short- and long-term mortality.

Background.Studies on depression and mortality in nursing homes have shown inconclusive findings, and none has studied the role of detection. We sought to measure the association of depression with long-term all-cause mortality in institutionalised older people and evaluate a potential modification in the association by its detection status.Methods.We selected a stratified cluster sample of 591 residents aged 75 years or older (mean age 84.5 years) living in residential and nursing homes of Madrid, Spain, who were free of severe cognitive impairment at the 1998–1999 baseline interview. Mortality was ascertained until age 105 years or September 2013 (median/maximum follow-up 4.8/15.2 years) through linkage to the Spanish National Death Index. Detected depression was defined at baseline as a physician's diagnosis or antidepressant use, undetected depression as significant depressive symptoms (score of 4 or higher on the ten-item version of the Geriatric Depression Scale) without documented diagnosis or treatment, and no depression as the absence of diagnosis, treatment, and symptoms. Constant and age-dependent hazard ratios for mortality comparing detected and undetected depression with no depression were estimated using Cox models, and absolute years of life gained and lost using Weibull models.Results.The baseline prevalences of detected and undetected depression were 25.9 and 18.8%, respectively. A total of 499 participants died during 3575 person-years of follow-up. In models adjusted for age, sex, type of facility, number of chronic conditions, and functional dependency, overall depression was not associated with long-term all-cause mortality (hazard ratio 0.87, 95% confidence interval (CI): 0.70–1.08). However, compared with no depression, detected depression showed lower mortality (hazard ratio 0.63, 95% CI: 0.46–0.86), while undetected depression registered higher, not statistically significant, mortality (hazard ratio 1.35, 95% CI: 0.98–1.86). The median life expectancy increased by 1.8 years (95% CI: −3.1 to 6.7 years) in residents with detected depression and decreased by 6.3 years (95% CI: 2.6–10.1 years) in those undetected. Results were more marked in women than men and they were robust to the exclusion of antidepressants from the definition of depression and also to the use of a stricter cut-off for the presence of depressive symptoms.Conclusions.The long-term mortality risk associated with depression in nursing homes depends on its detection status, with better prognosis in residents with detected depression and worse in those undetected. The absolute impact of undetected depressive symptoms in terms of life expectancy can be prominent.

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Acute Pulmonary embolism(PE)is a common and potentially fatal medical condition.In contemporary adult population,PE is associated with increased long-term mortality. Purpose Identify predictors of long-term all-cause mortality in patients(pts)admitted due to pulmonary embolism. Methods Retrospective single-center study of hospitalized pts with acute PE between 2015 and 2018.We evaluated comorbidities, admission(AD)presentation such as vitals(with hypotension defined as systolic blood pressure(SBP)&lt;90mmHg,and tachycardia as &gt;100ppm),lab analyses during in-hospital period,imaging features. Mortality(long-term &gt;3months)was also assessed using national registry of citizens.We performed uni and multivariate analysis to compare clinical characteristics of pts who died and who survived,using Cox regression and Kaplan-Meier methods.For the predictor age we assessed discrimination power and defined the best cut-off using area under the ROC curve(AUC)method. Results From 2015 to 2018,182 pts were admitted with diagnosis of pulmonary embolism,60% female with a mean age of 74 ± 13years old.Seventy-one(39%)pts died after a median follow-up of 26[10-41]months.Pts who died were older(80 ± 8 vs71 ± 14,p &lt; 0.001).The best cut-off value of age to predict mortality with 70%sensitivity and 61%specificity was 77years old(AUC 0.703;CI95% 0.63-0.78).Pts who died had more frequently history of neoplasia (21%vs 9%,p = 0.009).The remaining comorbidities were similar in both groups.Pts who did not survive were more frequently hypotensive(28% vs 13%, p = 0.008),had higher creatinine(1.1[0.8-1.4] vs 1.0[0.8-1.2], p = 0.002), lactate(2.3[1.8-2.8]vs 1.8[1.5-2.0],p = 0.007)and NT-proBNP(4694[1498-12300]vs2070[492-6660], p &lt; 0.001)at AD.Maximum troponin I (0.176[0.037-0.727]vs0.126[0.050-0.365]ng/mL,p = 0.012) was also higher than in pts who survived. After adjusting for history of neoplasia,ADcreatinine and maximum troponin I,we found that age (HR1.057;95%CI 1.01-1.11,p = 0.021),AD SBP &lt; 90(HR 2.215;95%CI 1.03-4.76,p = 0.041),lactate(HR 1.17;95%CI 1.01-1.36,p = 0.035)and NT-proBNP(HR 1.510;95%CI 1.250-1.780,p &lt; 0.001)were independent predictors of all-cause mortality. Conclusion In our cohort,the long-term all-cause mortality was 39%over a median  follow-up of 26[10-41]months.In patients with pulmonary embolism,aside from already identified age(especially when ≥70 years old)and NT-proBNP,lactate should also be considered when evaluating long-term prognosis. Furthermore,hypotension at admission increases by 2fold long-term mortality in patients who suffered acute PE.

Objectives A retrospective review of treatment of patients with massive or submassive pulmonary embolism (PE) using AngioJet rheolytic thrombectomy (ART) system with procedural modifications to improve on the previously reported outcomes. Materials and Methods Thirteen patients underwent emergent pulmonary artery thrombectomy for massive and submassive PE using ART with pharmacological and procedural modification, in comparison to prior reports. The modifications included the selective use of the Solent Omni AngioJet device in all subjects, distal contrast angiography via the AngioJet catheter before device activation, and limited short run times. Thrombolytic therapy was not used in any patient. Patients were monitored for short- and long-term outcomes. Long-term clinical follow-up and evaluation for persistent pulmonary hypertension with echocardiography was performed. Results The pharmacological and procedural modifications resulted in a favorable clinical response without any major complications and without any mortality. Procedure-related anemia (mean hemoglobin drop of 0.49 g/dl) was the only significant minor complication noted. There were no bleeding complications and no transfusion requirement. On a six-month follow-up, there was no mortality, and there were significant reductions in the pulmonary artery pressures. Conclusion Major and minor complications were reduced compared to prior reports using ART. A modified ART approach towards treatment of high-risk PE appears promising both in terms of efficacy and safety.
