Researchers say the results show the commonly held image of a man as the typical victim of chest pain is incorrect.

In the study, published in Circulation: Journal of the American Heart Association, researchers analyzed 53 studies on stable angina involving more than 400,000 people from 31 countries.
Overall, 13,331 cases of angina were reported among women and 11,511 among men. The results showed that women consistently suffered from higher rates of stable angina than men, regardless of age or menopausal status.
"We were surprised to see this slight excess of angina in women, although it had been reported before in a few individual studies," researcher Harry Hemingway, MD, professor of clinical epidemiology at the University College London Medical School, says in a news release.
"What surprised us much more was its consistency," Hemingway says. "We found the same female excess across 31 countries, across four decades of studies, and across four decades of ages."
The implications of this study are important in understanding quality of care. Even though women appear to exhibit more stable angina symptoms, other investigators have shown that they are less likely to be referred for stress testing and subsequent treatment.
The prevalence of stable angina varied widely among the 31 countries studied, from less than 1% to 14% in women with an average of 6.7% and from less than 1% to 15% in men with an average of 5.7%.
