Abstract

The relations of resting blood pressure, blood pressure during standardized stressors, and workplace blood pressure to left ventricular structure and diastolic filling were evaluated in 133 healthy young adults (mean age = 30 +/- 7 years) without hypertension. Each subject underwent the following: (a) measurement of basal blood pressure at the endof 15 minutes of rest; (b) measurement of blood pressure during a competitive reaction time task (a laboratory stressor which elicits a beta-adrenergically mediated increase in cardiac output); (c) measurementof blood pressure during a forehead cold pressor test, which results primarily in an increase in total peripheral resistance due to alpha-adrenergic stimulation; and (d) ambulatory blood pressure monitoring during a typical workday. Left ventricular structure (indexed left ventricular mass and relative wall thickness! and diastolic filling (peak filling velocity) were evaluated by echocardiography. All four measuresof systolic blood pressure were significantly correlated with indexedleft ventricular mass. The best predictor of indexed left ventricularmass was the systolic blood pressure during the cold pressor test (r = 0.32, p < 0.001), and this relation was significant after correctingfor resting systolic blood pressure (p < 0.05). Relative wall thickness was most closely related to the average ambulatory workplace systolic pressure (r = 0.23, p < 0.01), and this relation was also independent of resting systolic blood pressure (p < 0.05). Peak filling velocity was inversely related to the systolic pressure in response to each stressor, but the correlations with stress-induced pressures were not significant after correcting for resting levels of blood pressure. These results demonstrate an association of structural characteristics of the left ventricle with blood pressure responses to stress.
