Abstract:
The relationship of blood pressure status to three stress-related variables, anger, coping resources, and strain, was evaluated in 90 African American women. The majority of the participants (57%) were normotensive, 32% of the participants reported current use of hypertensive medication, and an additional 16% had a mean blood pressure greater than 140/90 mmHg but were not on hypertensive therapy. From an analysis using ANCOVA, participants in the latter group were found to have significantly higher scores on rational-cognitive coping resources, controlling for age, waist/hip ratio, and pack-years. No significant differences among the blood pressure groups were found in anger or personal strain. Fostering rational-cognitive coping skills, which represent the ability to problem-solve effectively and to set priorities, may be beneficial for African American women and should be evaluated further in a larger sample.

Factors affecting Blood pressure
Physiological Factors:
Hypertension and Regulation of Blood Pressure
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Blood Pressure
Hormonal Regulation of Blood Pressure
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
