Key result
Aging and disease development are linked to long-term ballistocardiogram alterations.
Why the study?
The effect of normal aging and the development of disease on the ballistocardiogram over a long interval was not previously determined.
How does normal aging and the development of disease affect the ballistocardiogram over time?
Cohort (n=80)
How does normal aging and the development of disease affect the ballistocardiogram over time?
This early study tracked longitudinal changes in ballistocardiograms to understand the effects of normal aging versus disease development.

Normal aging effects on BCG add historical context only; leaves open any role in contemporary cardiac assessment.
Second ballistocardiograms were taken on 80 subjects who were part of the series from which the original normal standards were secured in 1937, 1938 and 1939. Sixty-five of these subjects had retained good health during the long interval; by a comparison between their old and new records, the effect of "normal" aging on the ballistocardiogram has been determined. Fifteen subjects lost their health during the interval and two of them have died since the second test. The evolution of their ballistocardiograms has been compared with the development of their disabilities.

Starr et al. (1952) conducted a cohort in Aging and disease (n=80). Aging and disease development vs. Baseline records was evaluated on Evolution of ballistocardiograms. Aging and the development of disease altered the ballistocardiogram over a long interval in a cohort of 80 subjects, of whom 65 retained good health and 15 developed disabilities.
