Prognostic Role of Alveolar-Arterial Oxygen Pressure Difference in Acute Pulmonary Embolism

Prognostic value of arterial/alveolar oxygen tension ratio (a/APO2) in acute pulmonary embolism.

BACKGROUND Because the arterial/alveolar oxygen tension ratio (a/APO2) is relatively constant throughout the entire range of fractional inspired oxygen concentration (FiO2), its use in determining the prognosis of acute pulmonary embolism (APE) was investigated. METHODS AND RESULTS This study retrospectively assessed 202 consecutive patients with APE confirmed by computed tomography or high p...

Alveolar-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...

Prognostic role of brain natriuretic peptide in acute pulmonary embolism.

BACKGROUND Rapid, noninvasive, and accurate prognostic assessment with an inexpensive cardiac biomarker is an appealing approach for patients with acute pulmonary embolism (PE). METHODS AND RESULTS We measured at the time of admission the plasma level of plasma brain natriuretic peptide (BNP) to determine its utility in prognosticating the clinical course of 73 consecutive patients with acute...

Prognostic Impact of Thrombolysis in Myocardial Infarction Risk Index on Hospitalization Mortality of Patient with Acute Pulmonary Embolism

Introduction: Acute pulmonary embolism (PE) is one of the deadly cardiovascular diseases. One of the indexes proposed in these patients for risk stratification is the Thrombolysis in Myocardial Infarction (TIMI) risk index (TRI), which includes three parameters of systolic blood pressure, age, and heart rate. This study aimed to evaluate the predictive value of TRI on in-hospit...
