title: [Noninvasive studies of the left ventricular systolic function in patients over 65 years old].
abstract: Left ventricular functions were assessed in 96 patients (26 men, 70 women aged over 65 years; mean age 74.6 +/- 6.3 years) with various cardiovascular diseases (arterial hypertension, coronary heart disease, cardiomyopathy, various cardiac defects) by comparing various left-ventricular time intervals obtained from resting ECGs, apex cardiograms, carotid-pulse curves and phonocardiograms with left-ventricular ejection fractions by echocardiography. The correlations were strongest with the Weissler index (ratio of pre-ejection and left-ventricular ejection times), PEP/LVET (r = -0.76; P less than 0.001), with PEP itself (r = -0.65; P less than 0.001), as well as with rate-corrected PEP (r = -0.71; P less than 0.001). The plain chest X-ray did not make it possible to assess quantitatively patients with diminished cardiac pump function, despite radiological signs of congestion.
