Embolia polmonare in paziente in duplice terapia antipiastrinica per posizionamento di DES

Venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism (PE), is the third most frequent cardiovascular disease and is characterized by high mortality and disability rate. According to the 2014 European Society of Cardiology guidelines for the treatment of PE, anticoagulant therapy is recommended in patients with acute PE for a period of at least 3 months in order to prevent both early mortality and recurrence of VTE. To date, there are no studies conducted on the triple antithrombotic therapy in patients with VTE subjected to percutaneous coronary interventions. We report the case of an elderly patient in dual antiplatelet therapy following coronary revascularization and stenting. The patient, following an episode of PE with cardiac arrest after 12 days of hospitalization, was successfully treated with anticoagulant therapy with dabigatran in association with the dual antiplatelet therapy already in place (Cardiology)

Endothelial dysfunction in patients with spontaneous venous thromboembolism

Background and Objectives A high incidence of atherosclerotic lesions and cardiovascular events has been reported in patients with spontaneous venous thromboembolism. Endothelial dysfunction is an early marker of atherosclerosis and has predictive value for ischemic events. We have evaluated endothelial function in patients with a history of spontaneous venous thromboembolism.Design and Methods Patients with a history of symptomatic, objectively confirmed, spontaneous venous thromboembolism were included in a case-control study. Exclusion criteria were any known risk factors for cardiovascular diseases, other conditions associated with endothelial dysfunction, estro-progestinic therapy or pregnancy. Controls were age-(±5 years) and sex-matched subjects with the same exclusion criteria but without previous venous thromboembolism. Endothelial function was evaluated by the non-invasive measurement of flow-mediated vasodilation of the brachial artery and of plasma markers of endothelium activation; platelet activation parameters were also measured.Results Twenty-eight cases (8 females; mean age 59±15 years) and 28 controls (8 females; mean age 58±15) were studied. Flow-mediated vasodilation was 3.5±0.6% in cases (95% CIs: 2.2 to 4.8) and 5.7±0.6% (4.2 to 6.8) in controls (p=0.015). Brachial artery blood flow and hyperemic blood flow did not differ between the two groups. Plasma von Willebrand factor and soluble P-selectin levels were significantly higher in patients with venous thromboembolism, while plasma soluble CD40 ligand and urinary 11-dehydro-TxB2 levels were similar in cases and controls.Interpretation and Conclusions Patients with spontaneous venous thromboembolism have endothelial dysfunction, unlike age- and sex- matched controls. This finding suggests that spontaneous venous thromboembolism may be a condition associated with an enhanced risk of atherosclerosis

Timing and Predictors of Recanalization After Anticoagulation in Cerebral Venous Thrombosis.

BACKGROUND AND PURPOSE Vessel recanalization after cerebral venous thrombosis (CVT) is associated with favorable outcomes and lower mortality. Several studies examined the timing and predictors of recanalization after CVT with mixed results. We aimed to investigate predictors and timing of recanalization after CVT. METHODS We used data from the multicenter, international AntiCoagulaTION in the Treatment of Cerebral Venous Thrombosis (ACTION-CVT) study of consecutive patients with CVT from January 2015 to December 2020. Our analysis included patients that had undergone repeat venous neuroimaging more than 30 days after initiation of anticoagulation treatment. Prespecified variables were included in univariate and multivariable analyses to identify independent predictors of failure to recanalize. RESULTS Among the 551 patients (mean age, 44.4±16.2 years, 66.2% women) that met inclusion criteria, 486 (88.2%) had complete or partial, and 65 (11.8%) had no recanalization. The median time to first follow-up imaging study was 110 days (interquartile range, 60-187). In multivariable analysis, older age (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.03-1.07), male sex (OR, 0.44; 95% CI, 0.24-0.80), and lack of parenchymal changes on baseline imaging (OR, 0.53; 95% CI, 0.29-0.96) were associated with no recanalization. The majority of improvement in recanalization (71.1%) occurred before 3 months from initial diagnosis. A high percentage of complete recanalization (59.0%) took place within the first 3 months after CVT diagnosis. CONCLUSION Older age, male sex, and lack of parenchymal changes were associated with no recanalization after CVT. The majority recanalization occurred early in the disease course suggesting limited further recanalization with anticoagulation beyond 3 months. Large prospective studies are needed to confirm our findings

Outcome Prediction in Cerebral Venous Thrombosis: The IN-REvASC Score.

BACKGROUND We identified risk factors, derived and validated a prognostic score for poor neurological outcome and death for use in cerebral venous thrombosis (CVT). METHODS We performed an international multicenter retrospective study including consecutive patients with CVT from January 2015 to December 2020. Demographic, clinical, and radiographic characteristics were collected. Univariable and multivariable logistic regressions were conducted to determine risk factors for poor outcome, mRS 3-6. A prognostic score was derived and validated. RESULTS A total of 1,025 patients were analyzed with median 375 days (interquartile range [IQR], 180 to 747) of follow-up. The median age was 44 (IQR, 32 to 58) and 62.7% were female. Multivariable analysis revealed the following factors were associated with poor outcome at 90- day follow-up: active cancer (odds ratio [OR], 11.20; 95% confidence interval [CI], 4.62 to 27.14; P<0.001), age (OR, 1.02 per year; 95% CI, 1.00 to 1.04; P=0.039), Black race (OR, 2.17; 95% CI, 1.10 to 4.27; P=0.025), encephalopathy or coma on presentation (OR, 2.71; 95% CI, 1.39 to 5.30; P=0.004), decreased hemoglobin (OR, 1.16 per g/dL; 95% CI, 1.03 to 1.31; P=0.014), higher NIHSS on presentation (OR, 1.07 per point; 95% CI, 1.02 to 1.11; P=0.002), and substance use (OR, 2.34; 95% CI, 1.16 to 4.71; P=0.017). The derived IN-REvASC score outperformed ISCVT-RS for the prediction of poor outcome at 90-day follow-up (area under the curve [AUC], 0.84 [95% CI, 0.79 to 0.87] vs. AUC, 0.71 [95% CI, 0.66 to 0.76], χ2 P<0.001) and mortality (AUC, 0.84 [95% CI, 0.78 to 0.90] vs. AUC, 0.72 [95% CI, 0.66 to 0.79], χ2 P=0.03). CONCLUSIONS Seven factors were associated with poor neurological outcome following CVT. The INREvASC score increased prognostic accuracy compared to ISCVT-RS. Determining patients at highest risk of poor outcome in CVT could help in clinical decision making and identify patients for targeted therapy in future clinical trials

Direct Oral Anticoagulants in Old and Frail Patients with Atrial Fibrillation: The Advantages of an Anticoagulation Service

Despite the recent advancements, oral anticoagulation is still challenging in some patients and this is the case for old and frail patients. The large majority of frail patients with atrial fibrillation should receive anticoagulation since the associated benefits outweigh the risk of bleeding. A multidisciplinary consensus document on the use and prescription of direct oral anticoagulants (DOACs) in older and frail patients with atrial fibrillation has been recently published. In this manuscript we provide a comment on this document and add insights into the management of these patients. The new DOAC age had imposed a paradigm shift in the management of patients with the need for clinically-oriented services rather than laboratory-oriented services. In this paper we provide tools for a structured patient-oriented DOACs treatment service supported by a multidisciplinary approach

Data on the use of oral anticoagulants in nonagenarians with atrial fibrillation

The data presented in this article are related to the research article entitled “Patients aged 90 years or older with atrial fibrillation treated with oral anticoagulants: A multicentre observational study” [1]. This article unveils original data of a cohort of 546 patients aged 90 years or older with non-valvular atrial fibrillation treated with oral anticoagulants. Here, we describe the time course of ischemic stroke and systemic embolism and of major bleeding according to the presence of outcome predictors and report the causes of permanent discontinuation and of death. Furthermore, we report data on the incidence of ischemic stroke and systemic embolism, of major bleeding, of permanent discontinuation and of all-cause death comparing i) oral anticoagulant naïve users vs. long-term oral anticoagulant users, ii) patients on anticoagulant therapy for less than 2 years (new users) vs. patients on anticoagulant therapy for more than 2 years. The material of this data article provides a better understanding on the use of oral anticoagulants in this fragile population and facilitates further critical analysis. Moreover, it aims at highlighting the importance of increasing knowledge in patients aged 90 years or older. These patients are often excluded from or under-represented in clinical trials and cohort studies

Acute pulmonary embolism: mortality prediction by the 2014 European Society of Cardiology risk stratification model

The European Society of Cardiology (ESC) has proposed an updated risk stratification model for death in patients with acute pulmonary embolism based on clinical scores (Pulmonary Embolism Severity Index (PESI) or simplified PESI (sPESI)), right ventricle dysfunction (RVD) and elevated serum troponin (2014 ESC model). We assessed the ability of the 2014 ESC model to predict 30-day death after acute pulmonary embolism. Consecutive patients with symptomatic, confirmed pulmonary embolism included in prospective cohorts were merged in a collaborative database. Patients' risk was classified as high (shock or hypotension), intermediate-high (RVD and elevated troponin), intermediate-low (RVD or increased troponin or none) and low (sPESI 0). Study outcomes were death and pulmonary embolism-related death at 30 days. Among 906 patients (mean +/- SD age 68 +/- 16, 489 females), death and pulmonary embolism-related death occurred in 7.2% and 4.1%, respectively. Death rate was 22% in "high-risk" (95% CI 14.0-29.8), 7.7% in "intermediate-high-risk" (95% CI 4.5-10.9) and 6.0% in "intermediate-low-risk" patients (95% CI 3.4-8.6). One of the 196 " low-risk" patients died (0.5%, 95% CI 0-1.0; negative predictive value 99.5%). By using the 2014 ESC model, RVD or troponin tests would be avoided in about 20% of patients (sPESI 0), preserving a high negative predictive value. Risk stratification in patients at intermediate risk requires further improvement
