Venous thromboembolism (VTE) represents a relevant cause of morbidity in patients with solid-organ transplant (SOT), but there are scarce data on the management and outcomes in these patients. RIETE is a worldwide, ongoing observational registry of patients with objectively confirmed, acute VTE. We used the RIETE database to compare the clinical characteristics, treatment and outcomes in SOT recipients vs. non-recipients. From January 2001 to December 2019, 83,210 patients were enrolled in RIETE. Of these, 329 (0.4%) were SOT recipients: in the kidney 221, liver 41, lung 28 and heart 25. Median duration of anticoagulation was similar in SOT recipients and non-recipients (174 vs. 182 days). During anticoagulation, 1180 patients developed deep vein thrombosis (DVT) recurrences, 1028 pulmonary embolism (PE) recurrences, 2392 had major bleeding, 3119 non-major bleeding and 8157 died. SOT recipients had a higher rate of major bleeding (hazard ratio [HR]: 2.55; 95% CI: 1.62–3.84) and clinically relevant non-major bleeding (HR: 1.94; 95% CI: 1.23–2.93) than non-recipients, with no differences in the rates of DVT recurrences (HR: 0.96; 95% CI: 0.30–2.32), PE recurrences (HR: 1.11; 95% CI: 0.35–2.67) or death (HR: 0.98; 95% CI: 0.67–1.40). On multivariable analysis, only liver transplant recipients were at an increased risk for major bleeding compared to non-recipients (adjusted HR: 3.17; 95% CI: 1.02–9.87). Treatment of VTE in SOT recipients is associated with an increased risk of bleeding compared to non-recipients. This is mainly due to the influence of liver transplant recipients. In non-liver SOT recipients, the risk for bleeding was similar to that in non-recipients. • There are scarce data on the management of venous thromboembolism (VTE) in patients with solid-organ transplant (SOT). • We compared clinical characteristics, treatments and outcomes in SOT recipients with control patients (non-recipients). • SOT recipients present relevant different clinical characteristics. • SOT recipients are at an increased risk of both major bleeding and clinically relevant non-major bleeding. • Our findings support the need to improve anticoagulation in transplant recipients, particularly in liver recipients.

- Abstract
Objective: To determine the incidence, characteristics, and risk factors of pulmonary embolism (PE) among patients hospitalized for COVID-19.Patients and Methods: We performed a prospective observational study of a randomly selected cohort of consecutive patients hospitalized for COVID-19 infection between March 8, 2020 through April 25, 2020. All eligible patients underwent a computed tomography pulmonary angiography independently of their PE clinical suspicion and were pre-screened for a baseline elevated D-dimer level.Results: 119 patients were randomly selected from the 372 admitted to one tertiary hospital in Valencia (Spain) for COVID-19 infection during the period of study. Seventy-three patients fulfilled both the inclusion criteria and none of the exclusion criteria and were finally included in the study. Despite a high level of pharmacological thromboprophylaxis (89%), the incidence of PE was 35.6% (95% confidence interval [CI], 29.6 to 41.6%), mostly with a peripheral location and low thrombotic load (Qanadli score 18.5%). Multivariate analysis showed that heart rate (Hazard Ratio [HR], 1.04), room-air oxygen saturation (spO2) (HR, 0.87), D-dimer (HR, 1.02), and C-reactive protein (CRP) levels (HR, 1.01) at the time of admission were independent predictors of incident PE during hospitalization. A risk score was constructed with these four variables showing a high predictive value of incident PE (AUC-ROC: 0.86; 95% CI: 0.80 to 0.93).Conclusions: Our findings confirmed a high incidence of PE in hospitalized COVID-19 patients. Heart rate, spO2, D-dimer, and CRP levels at admission were associated with higher rates of PE during hospitalization. [ABSTRACT FROM AUTHOR]- Published

- Abstract
Background Pulmonary Vein Thrombosis (PVT) is a rare and underdiagnosed entity produced by local mechanical nature mechanisms, vascular torsion or direct injury to the vein. PVT has been described in clinical cases or small multicenter series mainly in relation to pulmonary vein stenosis, metastatic carcinoma, fibrosing mediastinitis, as an early surgical complication of lung transplantation lobectomy and radiofrequency ablation performed in patients with atrial fibrillation, although in some cases the cause is not known. Case We report the case of a 57 years old male with history of atrial fibrillation treated by radiofrequency ablation who was admitted in our center because of a two-week history of consistent pleuritic pain in the left hemithorax and low-grade hemoptysis and a lung consolidation treated as a pneumonia with antibiotic but not responding to medical therapy. In view of the poor evolution of the patient, computed tomography angiography was performed with findings of PVT and secondary venous infarction and anticoagulation therapy was optimized. At the end, pulmonary resection was performed due to hemorrhagic recurrence. Conclusion PVT remains a rare complication of radiofrequency ablation and other procedures involving pulmonary veins. Clinical suspicion and early diagnosis is crucial because is a potentially life-threatening entity. [ABSTRACT FROM AUTHOR]

The association between statin use and mortality in patients with deep vein thrombosis (DVT) has not been rigorously evaluated. We used the data in the RIETE registry to examine the association between statin use and mortality at 3 months. We used mixed effects survival models accounting for clinical covariates and clustering of patients in enrolling centers. From January 2009 through April 2022, there were 46,440 patients with isolated DVT in RIETE (in the lower-limbs 42,291, in the upper limbs 4149). Of these, 21 % and 18 %, respectively, were using statins. Statin users were older than non-users (72 ± 12 vs. 62 ± 18 years), and more likely had diabetes, hypertension, prior myocardial infarction or ischemic stroke, or were receiving antiplatelets. The 3-month mortality rates were: 6.0 % vs. 5.8 %, respectively. On multilevel multivariable analysis, the adjusted hazard ratio (aHR) for all-cause death in statin users vs. non-users was 0.77 (95%CI: 0.69–0.86). The 3-month risk of death in statin users was significantly lower than in non-users in patients with upper-limb DVT (aHR: 0.81; 95%CI: 0.72–0.91), distal lower-limb DVT (aHR: 0.48; 95%CI: 0.32–0.72), or proximal lower-limb DVT (aHR: 0.69; 95%CI: 0.50–0.95), and in those receiving simvastatin (aHR: 0.73; 95%CI: 0.60–0.90), atorvastatin (aHR: 0.70; 95%CI: 0.59–0.85), or rosuvastatin (aHR: 0.47; 95%CI: 0.27–0.80). Major bleeding, used as a falsification endpoint, did not show an association with use of statins at 3-month follow-up. Statin users with isolated DVT were at significantly lower risk for death at 3 months than non-users. • Statins possess antithrombotic and profibrinolytic properties • We compare the 3 months all-cause mortality in patients with DVT according to the use of statins • Statin users with isolated DVT were at lower adjusted risk for death at 3 months • Randomized trials are needed to confirm these data [ABSTRACT FROM AUTHOR]

Chronic thromboembolic pulmonary hypertension (CTEPH) is a long-term sequel to pulmonary embolism (PE) whose incidence varies according to different published studies. We have carried out this study to determine its incidence within 2 years after index pulmonary embolism and to study limitations to an early diagnosis. OSIRIS is a multicentre, longitudinal cohort study. Patients were followed for 3, 6, 12, and 24 months after pulmonary embolism using a structured three-step algorithm. A physician-centered questionnaire at least one positive response in a screening proceeded to the second step, transthoracic echocardiography. The third step consisted of ventilation/perfusion lung scintigraphy and right heart catheterisation. A transthoracic echocardiography was performed in patients without positive response in the screening questionnaire after 2 years. CTEPH diagnosis required haemodynamic confirmation by right heart catheterisation and mismatched perfusion defects on lung scintigraphy. A total of 1191 patients were enrolled in 18 Spanish hospitals. Cumulative CTEPH incidence after 2-years PE was: 2.49 % (95 % CI: 1.68–3.56) and the incidence rate of CTEPH was 1.1 cases per 1000 person-months (95 % CI: 0.725; 1.60). The CTEPH algorithm presented a lack of adherence of 29 %; patient and physician preferences posed barriers to the triage algorithm The screening questionnaire, in patients who completed the follow-up, shows a specificity of 91.3 % (89.0–93.2 %) and negative predictive value of 99.4 % (98.4–99.8 %).. OSIRIS provides practiced clinical based data on the chronic thromboembolic pulmonary hypertension incidence and identified barriers to the implementation of a 3-step triage algorithm for its detection. clinicaltrials.gov identifier: NCT03134898. [Display omitted] • Two-year cumulative incidence of Chronic Thromboembolic Pulmonary Hypertension (CTEPH) after pulmonary embolism (PE) was 2.49% (95% CI: 1.68-3.56) • A structured three-step diagnostic algorithm based on clinical assessment starting with a screening questionnaire showed limited feasibility, but a high negative predictive value • Observed barriers from patients and physicians to the implementation of a screening-based CTEPH diagnostic algorithm may support the planning of future studies and help to address training gaps [ABSTRACT FROM AUTHOR]

There is a paucity of data examining the prognostic significance of untreated obstructive sleep apnea (OSA) in hemodynamically stable patients with acute pulmonary embolism (PE). This prospective cohort study enrolled consecutive non-hypotensive patients with acute PE who underwent an overnight sleep study within 48 h after diagnosis. The patients were divided into 2 groups based on apnea-hypopnea index (AHI): OSA (AHI ≥15) and non-OSA (AHI <15) groups. The study used a composite of fatal or nonfatal cardiovascular events, including PE-related death, other cardiovascular deaths, clinical deterioration requiring an escalation of treatment, recurrent venous thromboembolism, acute myocardial infarction, or stroke within 30-days after the diagnosis of PE as the primary outcome. Between January 1, 2018, and December 31, 2020, 283 eligible patients were prospectively enrolled in 2 academic hospitals, of whom 268 patients completed a sleep study within 7 days of PE diagnosis. OSA was found in 47% (95% confidence interval [ CI ], 41 to 54%) of patients. The primary outcome occurred in 13 (4.9%) patients within 30-days after the diagnosis of PE. The crude incidence of the composite was not significantly different in the OSA than the non-OSA group (30-day estimate, 6.3% versus 3.5%; P = 0.30). OSA did not significantly predict the incidence of the primary outcome after adjustment for age, sex, body mass index, systolic blood pressure, heart rate, and oxygen saturation (adjusted hazard ratio, 2.15; 95% confidence interval, 0.67–6.87). In this study, untreated OSA was not a significant multivariable predictor of adverse cardiovascular events in patients with acute PE. • We investigated the prognostic significance of OSA in stable patients with PE. • We found a high prevalence of undiagnosed OSA among patients with acute PE. • Untreated OSA was not a significant predictor of adverse cardiovascular events in patients with acute PE.
