BACKGROUND Although echocardiography has proven utility in risk stratifying normotensive patients with pulmonary embolism, echocardiography is not always available. OBJECTIVE Test if a novel panel consisting of pulse oximetry, 12-lead electrocardiography, and serum troponin T would have prognostic equivalence to echocardiography and to examine the(More)
BACKGROUND Pregnancy is known to increase the D-dimer concentration above the conventional normal threshold of 0.50 mg/L, leading to an increased false-positive D-dimer test when venous thromboembolism (VTE) is clinically suspected in a pregnant patient. Our aim was to determine the effect of normal pregnancy on the D-dimer concentration. METHODS Healthy(More)
BACKGROUND No published data have systematically documented pulmonary artery pressure over an intermediate time period after submassive pulmonary embolism (PE). The aim of this work was to document the rate of pulmonary hypertension, as assessed noninvasively by estimated right ventricular systolic pressure (RVSP) of >or= 40 mm Hg 6 months after the(More)
STUDY OBJECTIVE This study tests the hypothesis that implementation of a point-of-care emergency department (ED) protocol to rule out pulmonary embolism would increase the rate of evaluation without increasing the rate of pulmonary vascular imaging or ED length of stay and that less than 1.0% of patients with a negative protocol would have an adverse(More)
PURPOSE A simple method is needed to risk stratify normotensive patients with pulmonary embolism. We studied whether bedside clinical data can predict in-hospital complications from pulmonary embolism. METHODS We performed a multicenter derivation phase, followed by validation in a single center. All patients were normotensive; the diagnosis of pulmonary(More)
OBJECTIVES The authors hypothesized that emergency department (ED) patients with a delayed diagnosis of pulmonary embolism (PE) will have a higher frequency of altered mental status, older age, comorbidity, and worsened outcomes compared with patients who have PE diagnosed by tests ordered in the ED. METHODS For 144 weeks, all patients with PE diagnosed(More)
OBJECTIVES The authors sought to determine the effect of in vitro time, temperature, and removable tourniquet use on changes in venous point-of-care lactate concentrations. METHODS This was a prospective randomized trial on healthy volunteers. Subjects were randomized to one of three groups: group 1 had venous lactate concentrations measured on blood(More)
AIMS We hypothesized that first-time submassive pulmonary embolism (PE) can cause persistent, significant cardiopulmonary problems, including right ventricular damage and worsened quality of life in patients with no prior cardiopulmonary disease. METHODS AND RESULTS We prospectively enrolled 205 patients without end-stage comorbidity diagnosed with(More)
Tenecteplase, a mutant form of alteplase, possesses pharmacological properties that might favor its use for emergent fibrinolysis of acute pulmonary embolism. Contemporaneous search of the World's literature reveals 14 humans with acute pulmonary embolism treated with tenecteplase. Here, we summarize those cases and report the presentation features, dosing(More)
STUDY OBJECTIVE We hypothesize that the presentation of a quantitative pretest probability of acute coronary syndrome would safely reduce unnecessary resource use in low-risk emergency department (ED) chest pain patients. METHODS Randomized controlled trial of adult patients with chest pain paired with their clinicians. Patients had neither obvious(More)
