The Journal Of The American Medical Association issued new findings about women's heart health.

Women, especially younger women, are more likely than men to show up at the hospital with no chest pain or discomfort after having a heart attack -- and they are also more likely to die than men of the same age, according to a U.S. study.

That lack of symptoms can result in delayed medical care and differences in treatment, said researchers, whose findings appeared in the Journal of the American Medical Association.

The same study suggests that women shouldn't second-guess any symptoms.

"If our results are in fact true, I would argue that rather than the one-size-fits-all symptom message, we also have to tailor that message to say that women less than 55 are also at higher risk for atypical presentation," Canto told Reuters Health.

Such "atypical presentation" can include symptoms such as unexplained shortness of breath, or pain in areas including the jaw, neck, arms, back and stomach.
