Clinical, historical and diagnostic findings associated with right ventricular dysfunction in patients with central and non-massive pulmonary embolism.

Right ventricular dysfunction during acute pulmonary embolism (PE) predisposes to hemodynamic instability and cardiogenic shock. Aim of this case-control study was to determine the clinical, historical and diagnostic findings associated with right ventricular dysfunction in patients with acute PE involving the main or segmental pulmonary arteries (central PE) and without hemodynamic instability on admission to the Emergency Department (ED) (non-massive PE). From January 1, 2002 to December 31, 2005, 211 patients with central PE were admitted to the Department of Emergency Medicine of the "Antonio Cardarelli" Hospital (Naples, Italy).

Predictors of in-hospital and long-term clinical outcome in elderly patients with massive pulmonary embolism receiving thrombolytic therapy.

Objectives: To determine the clinical, historical, and instrumental findings associated with unfavorable short-term and long-term prognosis in elderly patients (>or=65) receiving thrombolytic therapy for pulmonary embolism (PE).

Design: Case-control retrospective study.

Setting: General medicine acute care ward.

Increased troponin I predicts in-hospital occurrence of hemodynamic instability in patients with sub-massive or non-massive pulmonary embolism independent to clinical, echocardiographic and laboratory information.

Introduction: Whether in patients with acute central sub-massive or non-massive pulmonary embolism, mild troponin I increase (>0.03 mug/L) predicts in-hospital occurrence of hemodynamic instability and death independent to prognostically relevant clinical, laboratory and echocardiographic information is not fully established.

Methods And Results: We evaluated consecutively patients admitted to the Emergency Room for pulmonary embolism; those in stable hemodynamics in whom central pulmonary embolism was confirmed by spiral-computed tomography were recruited.
