Objective—Persons with elevated blood pressure show dampened emotional responses to affectladen stimuli. We sought to further examine cardiovascular emotional dampening by examination of the relationship between resting hemodynamic measures and recognition of emotion in an African-American community-based sample.
Methods—Participants were 106 African American men and women (55 female; mean age 52.8 years), mainly low in socioeconomic status and part of the Healthy Aging in Nationally Diverse Longitudinal Samples (HANDLS-Pilot) Pilot Study. Participants evaluated emotional expressions in faces and in sentences using the Perception of Affect Test (PAT). Resting blood pressure, total peripheral resistance (TPR), cardiac output and heart rate were obtained continuously using a Portapres blood pressure monitor.
Results—Total PAT scores were inversely related to systolic (r = −.30) and diastolic (r = −.24) blood pressure, TPR (r = −.36) and age (r = − .31; p values < .01), and positively related to cardiac output (r = .27) and education (r = .38; p values <.01), and with mental state (r = .25) and body mass index (r = −.20; p values < .05). Accuracy of emotion recognition on the PAT tasks remained inversely related to TPR and blood pressure after adjustment for demographic variables, medication, mental state and body mass index.
Conclusions—Elevated blood pressure and TPR were associated with reduced perception of affect. TPR was the most consistent independent hemodynamic correlate of emotional dampening for the PAT scores. These results suggest potentially important links among CNS regulation of emotions, hemodynamic processes and hypertension development.
