Official Title: Evaluation of Left Ventricular Filling Pressures During Exercise: Comparative Study, Catheterization Versus Echocardiography
Brief Summary:
Heart failure with preserved ejection fraction (HFPEF) is common and is a real public health issue. Diagnosis, especially when there are no congestive signs, is difficult. It has been shown that many patients with suspected HFPEF had left ventricular (LV) filling pressures elevated only at exercise (normal at rest).
Using stress echocardiography and taking into account left atrial (LA) remodeling at rest as a "memory" of chronic elevation of filling pressures. We believe that it is possible to improve the noninvasive diagnosis of exercise elevation of the LV end-diastolic pressure (LVEDP).
