Effects of treadmill exercise on mitral inflow and annular velocities in healthy adults

Tissue Doppler echocardiography has recently been introduced as a method to evaluate diastolic function by measuring diastolic mitral annular velocity. Mitral annular velocity derived by tissue Doppler echocardiography is relatively independent of preload, and tissue Doppler echocardiography combine...

Summary:Tissue Doppler echocardiography has recently been introduced as a method to evaluate diastolic function by measuring diastolic mitral annular velocity. Mitral annular velocity derived by tissue Doppler echocardiography is relatively independent of preload, and tissue Doppler echocardiography combined with transmitral flow velocity appears to provide a better estimate of left ventricular (LV) filling pressures compared with other methods, such as pulmonary venous flow pattern or preload reduction. However, exercise-induced changes in tissue Doppler echocardiography and mitral inflow velocities have not been characterized adequately. The purpose of this study was to evaluate transmitral inflow pattern and the tissue Doppler echocardiographic profile of a mitral annulus in healthy subjects during exercise; this would establish normal reference values to be used in a stress test to assess the extent of the elevation in diastolic filling pressure with exercise.
