Women Face More Stress than Males, Hinders Recovery from Heart Attack

A new study from Yale School of Medicine researchers discovers young and middle-aged women experience more stress than their male counterparts.

Experts believe this factor may contribute to worse recovery from an acute myocardial infarction (AMI), or heart attack.

The findings appear in the journal Circulation.

“Women tend to report greater stress and more stressful life events than men, potentially because of their different roles in family life and work, as compared to men,” said first author Xiao Xu,  Ph.D., assistant professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale School of Medicine.

“This difference in the level of stress may be an important reason for sex-based differences in recovery after acute myocardial infarction.”

Xu and her colleagues studied AMI patients 18 to 55 years old from a large, diverse network of 103 hospitals in the United States, 24 in Spain and three in Australia from 2008 to 2012.

The research team measured each patient’s self-perceived psychological stress during the initial hospital stay for AMI.

To do this, they used 14 questions, which asked participants about the degree to which their life situations during the last month were unpredictable, uncontrollable, and overloaded.

One sample question asked, “In the last month, how often have you been upset because of something that happened unexpectedly?” Response to each item was scored as never (0), almost never (1), sometimes (2), fairly often (3), and very often (4).

The team measured each patient’s recovery based on changes in their angina-specific and overall health status between initial hospitalization for AMI and one month after AMI.

Compared with men, women had significantly higher rates of diabetes, chronic lung disease, chronic renal dysfunction, depression, and cancer, as well as previous stents, congestive heart failure, and stroke.

Women were also more likely to have children or grandchildren living in their household, while experiencing greater financial strain.

“This study is distinctive in focusing particularly on young women and going beyond traditional predictors of risk to reveal how the context of these people’s lives influences their prognosis,” said senior author Harlan M. Krumholz, M.D., principal investigator of the study.

Xu added, “Helping patients develop positive attitudes and coping skills for stressful situations may not only improve their psychological well-being, but also help recovery after AMI.”

Experts recommend stress management interventions that recognize and address different sources of stress for men and women.
