Regional myocardial systolic function during acute myocardial ischemia assessed by strain Doppler echocardiography.
OBJECTIVES We sought to evaluate if echocardiographic strain measurements could detect acute myocardial ischemia, and to compare this new method with myocardial velocity measurements and wall motion score index. BACKGROUND Tissue Doppler echocardiography (TDE) is a promising method for assessing regional myocardial function. However, myocardial velocities measured by tissue Doppler echocardio...
متن کاملMyocardial strain by Doppler echocardiography. Validation of a new method to quantify regional myocardial function.
BACKGROUND Myocardial strain is a measure of regional deformation, and by definition, negative strain means shortening and positive strain, elongation. This study investigates whether myocardial strain can be measured by Doppler echocardiography as the time integral of regional velocity gradients, using sonomicrometry as reference method. METHODS AND RESULTS In 13 anesthetized dogs, myocardia...

متن کاملRegional myocardial work by strain Doppler echocardiography and LV pressure: a new method for quantifying myocardial function.
There is a need for better methods to quantify regional myocardial function. In the present study, we investigated the feasibility of quantifying regional function in terms of a segmental myocardial work index as derived from strain Doppler echocardiography (SDE) and invasive pressure. In 10 anesthetized dogs, we measured left ventricular (LV) pressure by micromanometer and myocardial longitudi...
متن کاملIntraventricular early diastolic filling during acute myocardial ischemia, assessment by multigated color m-mode Doppler echocardiography.
BACKGROUND Color M-mode Doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study investigated intraventricular filling pattern by color M-mode Doppler in patients during percutaneous transluminal coronary angioplasty (PTCA). In a dog model of myocardial ischemia, the color M-mode flow pattern was related to i...
