Pulmonary embolism: predicting disease severity.
Pulmonary embolism (PE) is the most common cause of acute pulmonary hypertension, yet it is commonly undiagnosed, with risk of death if not recognized promptly and managed accordingly. Patients typically present with hypoxemia and hypomania, although the presentation varies greatly, being confounded by co-morbidities such as pre-existing cardio-respiratory disease. Previous studies have demonst...
متن کاملAlveolar-arterial oxygen gradient in the assessment of acute pulmonary embolism.
PURPOSE The purpose of this investigation is to evaluate the utility of the alveolar-arterial (A-a) oxygen gradient in the diagnosis of acute pulmonary embolism (PE) among patients who participated in the Prospective Investigation of Pulmonary Embolism Diagnosis (PIO-PED). METHODS Pulmonary embolism was diagnosed (n = 280) or excluded (n = 499) by angiography in all patients. Patients were th...
متن کاملSimplification of the pulmonary embolism severity index for prognostication in patients with acute symptomatic pulmonary embolism.
BACKGROUND The Pulmonary Embolism Severity Index (PESI) estimates the risk of 30-day mortality in patients with acute pulmonary embolism (PE). We constructed a simplified version of the PESI. METHODS The study retrospectively developed a simplified PESI clinical prediction rule for estimating the risk of 30-day mortality in a derivation cohort of Spanish outpatients. Simplified and original P...
متن کاملPredictive value of troponins and simplified pulmonary embolism severity index in patients with normotensive pulmonary embolism
BACKGROUND To investigate whether 2 cardiac troponins [conventional troponin-T(cTnT) and high sensitive troponin-T(hsTnT)] combined with simplified pulmonary embolism severity index (sPESI), or either test alone are useful for predicting 30-day mortality and 6 months adverse outcomes in patients with normotensive pulmonary embolism(PE). METHODS The prospective study included 121 consecutive p...
متن کاملThe Pulmonary Embolism Severity Index in Predicting the Prognosis of Patients With Pulmonary Embolism
BACKGROUND/AIMS Many prognostic models have been developed to help physicians make medical decisions on treating patients with pulmonary embolism. Among these models, the Pulmonary Embolism Severity Index (PESI) has been shown to be a successful risk stratification tool for patients with acute pulmonary embolism. The PESI, however, had not been applied to patients with pulmonary embolism in Kor...
