Low Dose Catheter Directed Thrombolysis for Acute Pulmonary Embolism

Pulmonary Embolism

BETULA trial will compare the efficacy of low dose catheter directed thrombolysis (CDT) to unfractioned heparin (UFH) in patients with intermediary-high risk pulmonary embolism (PE). Patients (n=60) with acute intermediary-high risk PE will be randomized 1:1 to UFH (bolus 80 international units per kilo (IU/kg)) followed by 18 IU/kg/hour until activated partial thromboplastin time (APTT) is 2-2.5 of reference value) or CDT (4mg alteplase (r-tPA) per catheter, infusion over 2 hours) in an open label, outcome assessor blinded, randomized, controlled trial. Primary efficacy endpoint is improvement in right-/left ventricular ratio 24 hours after randomization. Secondary endpoints are 30 days mortality, recurrent PE, length of hospital stay and reduction in thrombus burden evaluated by pulmonary CT angio. Safety endpoints are minor and major bleedings.

STOPping Anticoagulation for Isolated or Incidental Subsegmental Pulmonary Embolism

Subsegmental Pulmonary Embolism Nos

Pulmonary embolisms (PE) occur when blood clots cause a blockage of the blood supply to the lungs. A small PE located in the subsegmental pulmonary vasculature is identified as a subsegmental PE (SSPE). Anticoagulants are used to treat SSPE and work by preventing new clots from forming whilst the body's own mechanisms break down the clots, however they can also increase the risk of major and potentially life threatening bleeding. More recent observational data of routine care for SSPE showed very high complication rates of anticoagulation but in patients where treatment was withheld, this proved to be a safe strategy in terms of recurrent venous thromboembolism (VTE). Computed tomography pulmonary angiography (CTPA) scans are now able to detect SSPE, however there are concerns that there is an over-diagnosis due to the incorrect interpretation of small artefacts. 1466 patients from approximately 50 sites will be recruited, these sites will consist of hospitals across the United Kingdom (UK). Patients 18 and over with isolated SSPE, confirmed by either CTPA or CT thorax with IV contrast, will be eligible for the trial. Patients will be randomised to either receive standard anticoagulation for at least 3 months (control) or no anticoagulation for at least 3 months (intervention). The participant will receive telephone follow up calls at 4, 12 and 24 weeks following the end of their treatment, and additional data will also be taken from their medical records at these time points. The participant isn't required to be contacted for the 52 week follow up as the data will be extracted from the National Health Service (NHS) Digital collection of Hospital Episode Statistics (HES). In total participation in the study will last 12 months. In addition the cost-effectiveness of no treatment versus treatment with full anticoagulation will be looked at and also improving on radiological diagnosis of SSPE.

Prospective Study for the Outpatient Treatment of Patients With Very Low Risk Acute Symptomatic...

Acute Pulmonary EmbolismOutpatient Treatment

Objectives: To evaluate the safety of outpatient treatment of patients with very low-risk pulmonary embolism (PE), and the satisfaction and quality of life of this management. Methods: An experimental study of routine clinical practice will be carried out in which 300 consecutive hemodynamically stable patients with acute symptomatic PE will be included, who meet all the inclusion criteria and none of the exclusion criteria. All patients included in the study will be treated on an outpatient basis, that is, they will be discharged within the first 24 hours of the diagnosis of PE in the Emergency Department. The Computerized Registry of Thromboembolic Disease RIETE (Registro Informatizado de Enfermedad TromboEmbólica) will be used to collect the data in electronic case report form (CRF) and ensure the quality of the data. Setting: Emergency, Pneumology and Internal Medicine Services of 10 Spanish hospitals. Analysis: An intention-to-treat (ITT) analysis will be performed on all patients who sign the informed consent and are included in the study (regardless of whether or not they receive the assigned strategy). Additionally, an analysis of all patients who are treated on an outpatient basis without deviations or violations of the protocol will be performed. The primary outcome considered will be the composite of recurrent PE, major bleeding, or death from any cause during the first 30 days after enrollment in the study. Patient satisfaction and quality of life will be considered as secondary outcomes.

Effects of Information and Breathing Technique - for Patients With Respiratory Pain in Acute Pulmonary...

Pulmonary Embolism

Acute pulmonary embolism (PE) is a serious disease and the third most common cardiovascular disease following myocardial infarction and stroke. The most common symptoms of acute PE are breathlessness and respiratory pain. Although many patients have respiratory pain in acute PE, the treatment of pain is not well described in literature. It is also unclear how long after acute PE the respiratory pain persists. In other conditions with respiratory associated pain, clinical treatment guidelines are available to avoid complications, such as pneumonia, related to impaired respiratory function. The purpose of this randomized controlled multicenter study is to evaluate the effect of a treatment, in patients with respiratory associated acute PE pain, consisting of information on anatomy and physiology in acute PE and breathing technique in addition to usual care treatment. The above treatment will be compared to conventional treatment in PE with respiratory associated pain, which means treatment with analgesics. One hundred sixty patients recruited from the Sahlgrenska University Hospital and Alingsås Hospital will participate in the study. Both groups are examined before and after interventions related to respiratory associated pain, measured with visual analogue scale (VAS), analgesic consumption, lung function measured with Peak Expiratory Flow (PEF), physical disability impairment measured by Disability Rating Index (DRI) and questions about the patients self-efficacy on managing their respiratory associated pain, days hospitalized, pneumonia rate during or after hospitalization, oxygen saturation and patient satisfaction. Both groups are followed from the inclusion date to 14 days after inclusion through physical visits by the physiotherapist during hospital care and by telephone contact after discharge. If the positive clinical experience of the information and breathing technique can be confirmed in the study, the method could be spread and used as an easily accessible new treatment method.

Interim Analysis: An interim analysis for the primary safety and efficacy outcomes will be performed when 300 subjects have completed 12-month follow-up.
