Emotional Stress Affects Women's Hearts
Mental stress test shows blood flow reduction among younger women compared to men and seniors, researchers report
SUNDAY, Nov. 16, 2014 (HealthDay News) -- Emotional stress is more likely to physically impact younger women with heart disease compared to men with heart disease and seniors of both genders, new research shows.
The study included 534 patients with stable coronary heart disease who were given a mental stress test that involved recalling a stressful life event and talking about it to a small audience.
During the test, nuclear imaging showed that women aged 55 and younger had a reduction in blood flow to the heart that was three times greater than men of the same age, and women aged 56 to 64 had coronary blood flow reduction twice that of men the same age.
There was no difference in coronary blood flow among women and men aged 65 and older during periods of emotional stress, according to the findings, which were to be presented Sunday at the American Heart Association annual meeting in Chicago.
The group was also given a physical stress test, in which women and men of all ages showed no differences in blood flow to the heart.
"Women who develop heart disease at a younger age make up a special high-risk group because they are disproportionally vulnerable to emotional stress," study author Dr. Viola Vaccarino, chairwoman of cardiovascular research and epidemiology at Emory University's School of Public Health, said in an AHA news release.
Many young and middle-age women face considerable levels of stress in everyday life as they try to manage children, marriage, jobs and caring for aging parents, she noted.
Doctors need to be aware that young and middle-age women are especially vulnerable to stress and to "ask the questions about psychological stress that often don't get asked," Vaccarino said.
"If they note that their patient is under psychological stress or is depressed, they should advise the woman to get relevant help or support from mental health providers, stress reduction programs or other means," she added.
Experts note that findings presented at medical meetings are often considered preliminary until published in a peer-reviewed journal.
