[Value of resting and exercise mitral regurgitation during exercise echocardiography to predict outcome in patients with left ventricular dysfunction].

Introduction And Objectives: The relative value of exercise echocardiography (EE) over resting echocardiography when this last incorporates information on mitral regurgitation (MR) is unknown. Furthermore, limited data exists regarding to the value of MR worsening during exercise in patients with LV dysfunction. We investigated whether: a) EE has incremental value over a resting echo-Doppler study; and b) post-exercise MR increments the value of EE for predicting outcome in patients with LV dysfunction.

Risk stratification by treadmill exercise echocardiography in patients with excellent exercise capacity.

Background: The incremental value of exercise echocardiography (EE) has been demonstrated to be maximal in patients with moderate pretest probability for coronary artery disease, but there is a lack of data in patients with low pretest probability or patients with good functional capacity.

Methods: To investigate whether such incremental value is maintained in patients with excellent exercise capacity, we studied 1,433 patients who had excellent exercise capacity (>or=8 METs for women, >or=10 METs for men).

Results: During a follow-up of 2.

Prognostic value of mitral regurgitation assessment during exercise echocardiography in patients with left ventricular dysfunction: a follow-up study of 1.7 +/- 1.5 years.

Aims: The value of exercise echocardiography (EE) over resting echocardiography when this last incorporates information on mitral regurgitation (MR) is only partially known. Furthermore, limited data exist regarding the value of MR worsening during exercise in patients with left ventricular (LV) dysfunction. We investigate whether EE has incremental value over a resting echo-Doppler study; and whether post-exercise MR increments the value of EE for predicting outcome in patients with LV dysfunction.

Prognostic value of mitral regurgitation assessment during exercise echocardiography in patients with known or suspected coronary artery disease.

Background: Although mitral regurgitation (MR) may be assessed during exercise echocardiography (EE) there are no data regarding its value for predicting outcome in large series of patients. We sought to determine whether the predictive value of EE is maintained over clinical variables and resting echocardiography when the latter included information on MR, and to verify whether postexercise MR may improve the value of EE for predicting outcome.

Methods: In all, 1916 patients (mean age +/- 1SD = 62 +/- 11 years; mean left ventricular ejection fraction +/- 1SD = 56 +/- 11) referred for EE were followed up for 1.

Risk stratification by treadmill exercise echocardiography.

Background: Although exercise echocardiography (EE) has value for the diagnosis of coronary artery disease (CAD), it's not clear whether it may be useful for risk assessment in all categories of patients. To determine whether: 1) there is an incremental value of EE over clinical, exercise and resting echocardiographic variables for the prediction of events according to the pre-test probability of CAD; and 2) the number, location of the diseased territories, and nature of the disease affect the risk stratification, we studied 2436 patients referred for EE that were followed for 2.1 +/- 1.

Comparison of exercise echocardiography and the Duke treadmill score for risk stratification in patients with known or suspected coronary artery disease and normal resting electrocardiogram.

Background: Although exercise echocardiography (EE) is not clearly indicated in patients with normal electrocardiogram (ECG) as the first evaluation, there is a lack of data regarding its superiority over the Duke score for prognosis. We investigate whether EE has incremental value over the Duke score for predicting outcome in patients with normal ECG.

Methods: One thousand six hundred forty-seven patients with interpretable ECG referred for EE were followed up for 2.
