Pulmonary embolism: CT signs and cardiac biomarkers for predicting right ventricular dysfunction.
The aim of this study was to prospectively evaluate the accuracy of quantitative cardiac computed tomography (CT) parameters and two cardiac biomarkers (N-terminal-pro-brain natriuretic peptide (NT-pro-BNP) and troponin I), alone and in combination, for predicting right ventricular dysfunction (RVD) in patients with acute pulmonary embolism. 557 consecutive patients with suspected pulmonary emb...

متن کاملRight ventricular dysfunction persists following brief right ventricular pressure overload.
OBJECTIVE Acute pulmonary hypertension may cause right ventricular (RV) contractile failure. While it has been assumed that restoration of normal loading conditions after acute pulmonary hypertension is sufficient for complete recovery of RV function, this has not been rigorously examined. The purpose of this study was to test the hypothesis that acute RV pressure overload produces RV contracti...
متن کاملPrognostic importance of right ventricular dysfunction.
When considering the entire range of left ventricular ejection fractions (LVEF) after a myocardial infarction, this parameter is a powerful predictor of mortality. However extended follow up studies have shown that prolonged survival occurs in some patients with congestive heart failure (CHF) who have adverse conventional prognostic markers, including very low LVEF. In patients with LVEF < 20%,...
متن کاملDiastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex
BACKGROUND Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic fashion. METHODS Patients with symptomatic bradycardia and ACC-AHA Class I indication for permanent pacemaker implantation (PPI) were implanted a s...
