Aging factors and cardiovascular dimensions: a longitudinal study.
The effects of selected aging factors including body weight, blood pressure, and radiation dose on the cardiac and aortic arch transverse diameters, based on posteroanterior and lateral radiographs obtained 17 to 22 years apart were evaluated for 200 normal subjects. Increases in body weight and blood pressure caused increases in transverse cardiac diameter of 26% and 2%, respectively, but no appreciable effect on aortic arch transverse diameter. Radiation dose caused no significant effects. Effects of increases in body weight and blood pressure on cardiac and aortic arch transverse diameters with age ought not be overestimated in healthy adults.
