Myocardial deformation by speckle tracking in severe dilated cardiomyopathy.
BACKGROUND The high and increasing prevalence of Dilated Cardiomyopathy (DCM) represents a serious public health problem. New technologies are being used aiming at more accurate diagnoses in order to improve therapeutic approach. In this scenario, speckle tracking echocardiography (STE) uses natural myocardial markers to analyze the systolic deformation of the left ventricle (LV). OBJECTIVE T...
متن کاملComparison of outcome between Chagas cardiomyopathy and idiopathic dilated cardiomyopathy.
BACKGROUND Little is known about the outcome of patients with Chagas cardiomyopathy in comparison to that of patients with idiopathic dilated cardiomyopathy in the contemporary era. OBJECTIVE To compare the outcome of chagasic patients with chronic systolic heart failure secondary to Chagas cardiomyopathy with that observed in patients with IDC in the contemporary era. METHODS A total of 35...
متن کاملIs atrial function in Chagas dilated cardiomyopathy more impaired than in idiopathic dilated cardiomyopathy?
AIMS Atrial function is an important component in overall cardiovascular performance. However, information on atrial function in dilated cardiomyopathy is limited. This study aimed to assess atrial function in dilated cardiomyopathy and to investigate if parameters of atrial function are more impaired in Chagas dilated cardiomyopathy (CDC) than in idiopathic dilated cardiomyopathy (IDC). METH...
متن کاملEstimation of left ventricular filling pressures by speckle tracking echocardiography in patients with idiopathic dilated cardiomyopathy.
AIMS the ratio of early diastolic transmitral flow velocity (E) to early diastolic mitral annular velocity (E(a)) is frequently used to predict an increase in left ventricular filling pressure (LVFP). However, this approach has several limitations. The aim of this study was to test whether additional information is gained by new echocardiographic indexes utilizing strain and strain rate (SR) de...
متن کاملRole of Speckle Tracking Echocardiography in Dilated Cardiomyopathy: A Review
Dilated cardiomyopathy (DCM) is an important cause of the heart failure. Timely diagnosis and optimal management decrease morbidity and mortality in heart failure patients. Although transthoracic echocardiography is used as the diagnostic test of choice in these patients, new modalities like speckle tracking echocardiography (STE) have promising results in diagnosing these patients in the earli...
