          Abstract

          Resumen Objetivo: Explorar la asociación entre consumo de estatinas (CE) y desarrollo de síndrome postrombótico (SPT). Método: Cohorte retrospectiva con pacientes con primer episodio de trombosis venosa profunda (TVP) entre el 06/2006 y el 12/2017, incluidos en el Registro Institucional de Enfermedad TromboEmbólica (RIET) del Hospital Italiano de Buenos Aires. Se consideró exposición al CE entre los 30 días previos y hasta 180 días posterior al diagnóstico de TVP. Se definió SPT según constaba este dato en la base de seguimiento del RIET. Se evaluó el desarrollo de SPT con un modelo de riesgos proporcionales de Cox, reportando hazard ratios (HR) crudas y ajustadas. Se consideró la confusión por indicación del CE y se utilizó un propensity score (PS) para el ajuste del riesgo estimado, reportando los HR con sus intervalos de confianza del 95% (IC 95%). Resultados: Se incluyeron 905 pacientes, de los cuales 273 fueron CE y 632 no consumidor de estatinas (NCE). Al seguimiento, la incidencia de SPT fue: 6.59% (18) en el grupo CE y 8.07% (51) en el grupo NCE, con p = 0.412. La razón de riesgo para el desarrollo de SPT de CE resultó no significativa (HR cruda: 0.78; IC 95%: 0.43-1.41; p = 0.414). La HR de CE ajustada por edad, sexo, antiinflamatorios no esteroideos, corticosteroides, inmovilidad, anticoagulante, hipertensión arterial, diabetes, dislipidemia, insuficiencia renal crónica, enfermedad coronaria, accidente cerebrovascular, insuficiencia cardiaca y enfermedad oncológica fue 0.45 (IC 95%: 0.13-1.5; p = 0.196). La HR del CE ajustado por edad, sexo, antiinflamatorios no esteroideos, corticosteroides, inmovilidad, tratamiento anticoagulante, enfermedad oncológica y PS fue de 0.52 (IC 95%: 0.17-1.66; p = 0.272). Conclusiones: El CE no se asoció con menor SPT, aunque hubo escaso número de eventos detectados.

          Abstract Objective: To evaluate the association between statin consumption and development of post-thrombotic syndrome (PTS). Methods: Retrospective cohort study which included patients with a first episode of deep vein thrombosis (DVT) between 06/2006 and 12/2017, included in the Institutional Registry of ThromboEmbolic Disease of the Italian Hospital of Buenos Aires, Argentina. Exposure to statin use (SU) was considered between the 30 days before and up to 180 days after the diagnosis of DVT. PTS was defined as recorded dataset on registry. The development of PTS was evaluated with Cox proportional hazards model, raw and adjusted hazard ratios (HR) were reported. Confusion was considered by indication of SU and a propensity score (PS) was used for adjustment. We reported HR with their 95% confidence interval (CI); p value < 0.05 was considered statistically significant. Results: Of 1393 patients, 905 were included for the analysis, of which 273 were SU and 632 non-statin users (NSU). At follow-up, incidence of PTS was: 6.59% (18) in the SU group and 8.07% (51) in the NSU group, with p = 0.412. Crude HR for PTS for SU was not significant (0.78; 95% CI: 0.43-1.41; p = 0.414). Adjusted HR of SU by age, sex, non-steroidal anti-inflammatory drugs, corticosteroids, immobility, anticoagulant, high blood pressure, diabetes, dyslipidemia, chronic renal failure, coronary heart disease, stroke, heart failure and cancer disease was 0.45 (95% CI: 0.13-1.5; p = 0.196) for PTS. While HR for the development of PTS adjusted by age, sex, non-steroidal anti-inflammatory drugs, corticosteroids, immobility, anticoagulant treatment, cancer disease and PS of the SU was 0.52 (95% CI: 0.17-1.66; p = 0.272). Conclusion: No statistically significant association was found between CE and the development of SPT, although there were a small number of events detected in both groups.

            Thrombosis: a major contributor to the global disease burden.

            Thrombosis is a common pathology underlying ischemic heart disease, ischemic stroke, and venous thromboembolism (VTE). The Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study 2010 documented that ischemic heart disease and stroke collectively caused one in four deaths worldwide. GBD 2010 did not report data for VTE as a cause of death and disability. We performed a systematic review of the literature on the global disease burden caused by VTE in low-income, middle-income and high-income countries. Studies from western Europe, North America, Australia and southern Latin America (Argentina) yielded consistent results, with annual incidence rates ranging from 0.75 to 2.69 per 1000 individuals in the population. The incidence increased to between 2 and 7 per 1000 among those aged ≥ 70 years. Although the incidence is lower in individuals of Chinese and Korean ethnicity, their disease burden is not low, because of population aging. VTE associated with hospitalization was the leading cause of disability-adjusted life-years (DALYs) lost in low-income and middle-income countries, and the second most common cause in high-income countries, being responsible for more DALYs lost than nosocomial pneumonia, catheter-related bloodstream infections, and adverse drug events. VTE causes a major burden of disease across low-income, middle-income and high-income countries. More detailed data on the global burden of VTE should be obtained to inform policy and resource allocation in health systems, and to evaluate whether improved utilization of preventive measures will reduce the burden.

              Pulmonary embolism and deep vein thrombosis.

              Pulmonary embolism is the third most common cause of death from cardiovascular disease after heart attack and stroke. Sequelae occurring after venous thromboembolism include chronic thromboembolic pulmonary hypertension and post-thrombotic syndrome. Venous thromboembolism and atherothrombosis share common risk factors and the common pathophysiological characteristics of inflammation, hypercoagulability, and endothelial injury. Clinical probability assessment helps to identify patients with low clinical probability for whom the diagnosis of venous thromboembolism can be excluded solely with a negative result from a plasma D-dimer test. The diagnosis is usually confirmed with compression ultrasound showing deep vein thrombosis or with chest CT showing pulmonary embolism. Most patients with venous thromboembolism will respond to anticoagulation, which is the foundation of treatment. Patients with pulmonary embolism should undergo risk stratification to establish whether they will benefit from the addition of advanced treatment, such as thrombolysis or embolectomy. Several novel oral anticoagulant drugs are in development. These drugs, which could replace vitamin K antagonists and heparins in many patients, are prescribed in fixed doses and do not need any coagulation monitoring in the laboratory. Although rigorous clinical trials have reported the effectiveness and safety of pharmacological prevention with low, fixed doses of anticoagulant drugs, prophylaxis remains underused in patients admitted to hospital at moderate risk and high risk for venous thromboembolism. In this Seminar, we discuss pulmonary embolism and deep vein thrombosis of the legs. Copyright © 2012 Elsevier Ltd. All rights reserved.
