Ballistocardiographic evaluation of the cardiovascular aging process.

چکیده
CARDIOVASCULAR aging is a complex phenomenon associated with a gradual, yet progressive, deterioration in cardiovascular function.1-3 The etiology of this deterioration in function is poorly understood, but atherosclerosis and, in particular, coronary artery disease seem to be a factor. Cardiovascular aging and atherosclerosis appear to be universal phenomena, but their rate of development and the extent of myocardial involvement are variable. When there is accelerated cardiovascular aging, clinical disease develops at an unusually early age. Thus, coronary atherosclerosis is not limited to older age groups, and coronary artery disease has been demonstrated in a large number of young, healthy men aged 20 to 40.4-7 The clinical evaluation of the cardiovascular aging process has been difficult, for usually there are no signs or symptoms detectable until overt disease is present. The ballistocardiogram has been used for many years in the evaluation of cardiovascular function. This technic offers a unique means of studying the change in cardiovascular dynamics with age. Recently, Reeves et al.8' 9 described an ultralow frequency acceleration ballistocardiograph that met all theoretic considerations of biophysical design.'0-14 This ballistocardiograph was clinically adaptable, had high testretest reliability, and revealed considerable new information about cardiovascular events. The purpose of the present study is to elucidate with the Reeves technic the changing ballistocardiographic pattern with advancing age in an overtly healthy male population,
