Abstract

This study was performed to assess whether the combination of multiple echocardiographic and Doppler variables can provide a reliable estimation of pulmonary artery wedge pressure in patients with chronic heart failure. In patients with chronic heart failure a high pulmonary artery wedge pressure is associated with poor prognosis, more severe symptoms and low exercise tolerance. Several Doppler echocardiographic indexes have been shown to be related to pulmonary artery wedge pressure, but the dispersion of data has generally not allowed a quantitative assessment of this important variable. Simultaneous Doppler echocardiographic examinations and right heart catheterizations were performed in 231 patients with chronic heart failure due to dilated cardiomyopathy. Mitral and pulmonary venous flow velocity variables, left atrial volumes, mitral regurgitation jet area and left ventricular ejection fraction were correlated with pulmonary artery wedge pressure by both single and multilinear regression analysis. The reliability of the obtained multilinear equations was then tested in a separate group of 60 patients. By univariate analysis, the deceleration rate of early diastolic mitral flow and the systolic fraction of pulmonary venous...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
