[Congestive heart failure in the elderly. Value of Doppler echocardiography].
Fifty-eight consecutive elderly patients (seven men and 51 women, mean age 84 +/- 6) admitted for congestive heart failure were prospectively investigated by doppler echocardiography in order to 1) define the prevalence of cardiac failure with normal left ventricular systolic function, 2) estimate the role of abnormalities of left ventricular filling (diastolic dysfunction), 3) evaluate echodoppler parameters for assessment of diastolic function: ratio of early peak on atrial peak of filling velocities (E/A), mitral deceleration time (MDT) and isovolumic relaxation time (IRT). Of the 58 patients, 32 (55%) had normal left ventricular systolic function and 26 (45%) had systolic dysfunction. Of the 32 patients with normal systolic function, diastolic function could not be evaluated in nine patients, was abnormal in 16 and normal in seven. Congestive heart failure with normal systolic function is very frequent in the elderly subject. Sensitivity of clinical data being too low, doppler echocardiography is the easiest noninvasive technique for defining abnormalities of both left ventricular systolic and diastolic function. In the elderly, MDT and IRT are more sensitive parameters than E/A for the diagnosis of diastolic dysfunction.
