Abstract

The left ventricular ejection fraction (EF) was studied in 17 healthy volunteers with a new ambulatory left ventricular function monitor. Heart rate, EF, and blood pressure measurements were made during rest, a psychiatric stress interview, cold exposure, exercise, and eating. An increase in EF was seen during emotional stress (from 0.45±0.09 to 0.51±0.13, P<0.001). This increase was comparable to that observed during exercise (0.52±0.14) and eating (0.52±0.10, P<0.001). In contrast, cold exposure caused a decrease in EF (0.43±0.13, P<0.05). These observations demonstrate the powerful hemodynamic consequences of common behaviors as well as the utility and feasability of studying such behavioral factors in ambulatory subjects.
