Abstract

BACKGROUND: Normal values for echocardiographic measurements and the relationship between these parameters and age in a large Japanese population are still unknown. METHODS AND RESULTS: A total of 700 healthy Japanese aged 20-79 years underwent 2-dimensional and Doppler echocardiography at collaborating institutions. The respective mean values obtained in men and women were as follows: septal wall thickness, 0.9+/-0.1 and 0.8+/-0.1 cm; posterior wall thickness, 0.9+/-0.1 and 0.8+/-0.1 cm; left ventricular (LV) diastolic diameter, 4.8+/-0.4 and 4.4+/-0.3 cm; LV systolic diameter, 3.0+/-0.4 and 2.8+/-0.3 cm; LV diastolic volume, 93+/-20 and 74+/-17 ml; LV systolic volume, 33+/-20 and 25+/-7 ml; LV ejection fraction, 64+/-5 and 66+/-5%; maximum left atrial (LA) volume, 42+/-14 and 38+/-12 ml. Aortic root diameter, LV wall thickness, and LV mass slightly increased with age, whereas indexed LA volume did not vary with age. Diastolic parameters assessed by mitral inflow and mitral annular velocities declined with age, as previously reported. CONCLUSIONS: Normal values of echocardiographic measurements in a large Japanese population are reported for the first time; several systolic and diastolic parameters varied with age. These results provide important reference values that should be useful in routine clinical practice as well as in clinical trials.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
