Background: Electrocardiography (ECG) signs, typical or acute pulmonary embolism, and their changes can be used for the prediction of clinical and haemodynamic outcomes. Purpose: To study the predictive value of the resolution of admission ECG signs in higher risk pulmonary embolism patients for 30-day survival and for the decrease in right ventricular systolic pressure. Methods: We analysed the 12-lead ECGs at admission and daily for the first 5 days after hospitalisation in 110 intermediate-high and high-risk pulmonary embolism patients admitted to the intensive care unit of a single tertiary centre. The predictive value of the resolution of four ECG signs were analysed for 30-day survival and for the changes in right ventricular systolic pressure during hospitalisation: S-wave in the first standard lead, right bundle branch block pattern, S-wave in the aVL lead and negative T-waves in precordial leads. Results: ECG recordings showed the existence of S-wave in the I lead in 71 (64.5%), S-wave in the aVL in 77 (70%), right bundle branch block pattern in 30 (27.3%) and negative T-waves in 66 (60%) patients. All-cause 30-day in-hospital mortality was 13.6%. Among the ECG signs, only the presence of right bundle branch block at admission was significantly associated with 30-day all-cause mortality (hazard ratio (HR) adjusted for age, gender and right ventricular systolic pressure at admission was 7.7, 95% confidence interval (CI) 2.1–27.9; P=0.002). The resolution of three ECG signs during the first 5 days of hospitalisation, S-wave in the I lead (HR 26.4, 95% CI 3.1–226.6; P=0.003), S-wave in the aVL (HR 21.5, 95% CI 2.6–175.3; P=0.004) and right bundle branch block configuration (HR 5.2, 95% CI 1.3–20.8; P=0.020) were associated with 30-day survival. The intermediate-high and high-risk pulmonary embolism patients with S-wave resolution in lead aVL had 0.0% and 7.1% 30-day all-cause mortality, respectively. The patients with resolution of the S-wave in the first lead and in aVL as well as right bundle branch block had more pronounced changes in right ventricular systolic pressure at discharge (27±13 vs. 13±15 mmHg; P=0.011 for S-wave in I lead resolution, 27±12 vs. 15±17 mmHg; P=0.004 for S-wave in aVL resolution and 23±14 vs. 9±14 mmHg; P=0.040 for right bundle branch block resolution) than patients without resolution. Conclusion: Resolution of S-waves and right bundle branch block in ECG correlates with lower all-cause 30-day mortality in intermediate-high and high-risk pulmonary embolism patients. Resolution of S-waves in the first lead and in aVL and right bundle branch block correlates with a decrease of right ventricular systolic pressure.

IntroductionRecent studies report that syncope is not a significant predictor of 30‐day mortality in pulmonary embolism (PE) patients, yet some data suggest sex‐related differences may be relevant.ObjectivesTo evaluate sex‐specific prediction significance of syncope for 30‐day mortality in PE patients.MethodsA multicentric, retrospective, observational, registry‐based study on consecutive PE patients was undertaken. Patients were allocated into either a men or a women group before comparisons were made between patients with syncope and those without syncope. A sex‐related prediction of the significance of syncope for 30‐day mortality was evaluated.ResultsOverall 588 patients [294 (50%) men and 294 (50%) women] were included within the study. Among men, patients with syncope were older and had significantly higher parameters of increased 30‐day mortality then patients without syncope. Within the same group, however, difference in the 30‐day mortality rate was not significant (log rank P = .942). In contrast to the men, fewer differences in admission characteristics were noticed among women, but those with syncope had significantly increased signs of the right ventricular dysfunction and increased 30‐day mortality rate, as compared with those without syncope (log rank P = .025). After adjustment for age in a Cox regression analysis, syncope was a significant predictor of 30‐day mortality in women (HR = 2.01, 95%CI 1.02‐3.95).ConclusionAlthough syncope is associated with other predictors of higher early mortality in both male and female PE patients, only in women it is a significant predictor of 30‐day mortality.

Aims This study aimed to investigate whether the risk of short-term mortality is different in pulmonary embolism (PE) patients who have heart failure with reduced ejection fraction (HFrEF) as compared with those with heart failure with preserved ejection fraction (HFpEF). Methods and results Predictive value of HFrEF or HFpEF for 7-day (intrahospital) and 30-day all-cause mortality was determined in the cohort of 1055 out of 1201 consecutive acute PE patients from the Serbian multicentre PE registry. Patients were classified into either HFrEF or HFpEF group, according to guideline-proposed criteria. A 7-day (intrahospital) and 30-day all-cause mortality was 18.5% vs. 7.3% vs. 4.5% (P < 0.001) and 22.2% vs. 16.3% vs. 7.9% (P < 0.001) for patients with the history of HFrEF, HFpEF, and without HF, respectively. Multivariable analysis adjusted to age, gender, history of chronic obstructive pulmonary disease, diabetes mellitus, arterial hypertension, presence of atrial fibrillation, and mortality risk assessment at admission has shown that only HFrEF, but not HFpEF, was an independent predictor for 7-day mortality (hazard ratio 2.22, 95% confidence interval 1.25-4,38.41, P = 0.021) and neither HFrEF or HFpEF was an independent predictor for 30-day mortality. Among various admission parameters associated to PE outcome, only systolic pressure in HFrEF patients (P < 0.001), heart rate (P = 0.01), and right ventricle systolic pressure (P = 0.039) in HFpEF patients were significantly different in patients who died compared with those who survived at 7 days. Conclusions Our study has shown that the presence of previous history of HFrEF, but not HFpEF, in acute PE is an independent risk factor for mortality at 7 days.

In patients with pulmonary embolism different ECG patterns at admission correlate with different clinical, ultrasound and MDCT-PA parameters. RBBB is associated with shock, Swave in the aVL is associated with right ventricle pressure and negative T-waves with the thrombus burden in the pulmonary tree.

Background Combining vedolizumab with a rapid-onset drug such as cyclosporine is a novel combination treatment for severe steroid-resistant ulcerative colitis (UC). This prospective study describes the efficacy and safety of cyclosporine in conjunction with vedolizumab in patients with severe, steroid-resistant UC with 1 year of follow-up. Methods Seventeen steroid-resistant UC patients were treated with cyclosporine in combination with vedolizumab, with a follow up of 52 weeks. Clinical and endoscopic response, remission rates, and colectomy-free survival were the primary endpoints. Secondary endpoints included biochemical response and remission with C-reactive protein, erythrocyte sedimentation rate, and fecal calprotectin. Results Fifteen (88%) of 17 patients initially responded to cyclosporine and were started on vedolizumab. By week 10, 11 (73%) of 15 patients had achieved endoscopic remission with a Mayo score of ≤1. At week 26, 14 (93%) of 15 of the patients were in clinical remission and 11 (73%) were in endoscopic remission. At week 52 of follow-up, 10 (71%) of 14 of these patients continued to be in endoscopic remission and 11 (79%) of 14 were in clinical remission. Among the 10 patients in endoscopic remission, 8 (80%) reached histological remission. Colectomy-free survival rate was 82% (n = 14 of 17) at 1 year and mean C-reactive protein, erythrocyte sedimentation rate, and fecal calprotectin levels were 3.2 mg/L, 16.1 mm/h, and 168.3 µg/g, respectively. No serious adverse events were reported. Conclusions Bridging cyclosporine to vedolizumab in severe, steroid-refractory UC patients is effective and safe at inducing and maintaining clinical, endoscopic, and biochemical response and remission up to 52 weeks of follow-up. Larger prospective studies are warranted.

Summary What is known and Objective Direct oral anticoagulants (DOACs) are frequently used for the treatment of pulmonary embolism (PE), but both clinical and laboratory data comparing their efficacy and safety are conflicting. This study investigated and compared the impact of three DOACs (apixaban, rivaroxaban and dabigatran) on coagulation cascade in acute PE patients. Methods After the initial treatment, acute PE patients were randomly allocated to one of three groups, and treatment continued using one of the three DOACs. Following 1 month of treatment, the activity of factors II, VII and VIII, as well as protein C, antithrombin, D‐dimer and fibrinogen, were measured, and the values were compared between the groups. Results and Discussion One hundred consecutive PE patients were included. The mean values for the activity of factors II and VII and protein C were higher in patients on apixaban than in patients on rivaroxaban (1.45 ± 1.12 (IU/mL) vs 1.13 ± 0.92 (IU/mL), P < 0.001; 1.24 ± 1.10 (IU/mL) vs 1.05 ± 0.98 (IU/mL), P = 0.024 and 1.15 ± 0.62 vs 1.02 ± 0.68 (IU/mL), P = 0.019, respectively). The mean of factor II activity and the median of factor VIII activity were also significantly higher in patients on apixaban than in patients on dabigatran (1.45 ± 1.12 vs 1.20 ± 0.96 (IU/mL), P = 0.003 and 2.9 (2.0‐4.0) vs 2.1 (1.5‐2.7) (IU/mL), P = 0.001, respectively). No difference was noticed in D‐dimer concentrations, or in the activity of the other factors measured. Additionally, no difference was noticed between the rivaroxaban and dabigatran groups. What is new and Conclusion Apixaban had a significantly higher thrombin activity, above the laboratory determined normal range, compared to patients on rivaroxaban and dabigatran. This higher thrombin activity in patients on apixaban may contribute to a better haemostatic response during the therapy or increased prothrombotic state after therapy interruption.
