ABSTRACT
INTRODUCTION: Recent 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. OBJECTIVES: To evaluate sex-specific prediction significance of syncope for 30-day mortality in PE patients. METHODS: A 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. RESULTS: Overall 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). CONCLUSION: Although 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.

Background: Systemic thrombolytic therapy is not recommended for patients with intermediate-risk pulmonary embolism (PE) because of major bleeding and intracranial bleeding overcomes the benefit of reperfusion.Patients and methods: A total of 342 PE patients with intermediate-risk PE from the multicenter Serbian PE registry were involved in the study. Of this group, 227 were not treated with reperfusion therapy (anticoagulation only), 91 were treated with conventional thrombolysis protocols at the discretion of their physicians and 24 patients were treated with ultrasound assisted catheter thrombolysis (USACT) with the EKOS® system. All patients treated with USACT had at least one factor which is associated with an increased risk of bleeding. Other patient characteristics were similar across the treatment groups. All-cause and PE-related mortality at 30 days and rate of major bleeding at 7 days were the main efficacy and safety outcomes of the study.Results: The 30-day all-cause mortality were 11.5% versus 17.6% versus 0.0% for no reperfusion, conventional thrombolysis protocols and USACT groups (p = 0.056), respectively. The difference between the rate of 30-day PE-related mortality was in a favour of EKOS and no reperfusion compare to conventional protocols (0.0% vs. 3.5% vs. 11.0%, p = 0.013, respectively). Major bleeding at 7 days, was presented in 1.8% versus 7.7% versus 8.0% (p = 0.021) in no reperfusion, conventional thrombolysis and USACT groups with no intracranial bleeding.Conclusion: In the patients with intermediate-risk PE and at least one bleeding factor, USACT could be an alternative treatment to anticoagulant therapy only and conventional thrombolytic protocols.
ABSTRACT
Factors associated with provoked PE may influence a biomarker's predictive value for the primary outcome. The aim of this study was to investigate the value of BNP, cTnI, CRP and D-Dimer measurements taken soon after hospital admission for the prediction of 30-day PE-caused death in patients with spontaneous versus provoked PE.Data were extracted from a pool of 726 consecutive PE patients enrolled in the multicenter Serbian PE registry. Blood concentrations of BNP, cTnI, CRP and D-dimer were measured during the first 24â¯h of hospitalization. BNP blood level had strong predictive value for the primary outcome in spontaneous PE (c-statistics 0.943, 95% CI 0.882-1.000, pâ¯=â¯.001) and a slightly lower predictive outcome in provoked PE (c-statistics 0.824, 95% CI 0.745-0.902, pâ¯<â¯.001). NRI and IDI showed that none of the markers, when added to BNP, could improve Cox regression prediction models for 30-day PE-related mortality in either the spontaneous or provoked PE group. Blood levels of BNP measured during the first 24â¯h of hospital admission had an excellent predictive value for 30-day PE-related mortality in spontaneous PE and slightly lower predictive value in provoked PE, whereas CRP, cTnI and D-Dimer did not contribute significantly to the predictive value of BNP in either group.
