Women more often have no chest pain with a heart attack and have a greater risk of dying in hospital than men do.

Almost 40% more women had no chest pain at diagnosis, and they had a 42% higher in hospital mortality, researchers reported in the Feb. 22/29 issue of theĀ Journal of the American Medical Association.

The youngest women with MI were most likely to have no chest pain and also had the highest mortality.

Absence of pain is associated with delayed diagnosis, less aggressive treatment, and a twofold higher short-term mortality.

Young female heart attack patients might have an increased mortality risk, and absence of chest pain or discomfort might contribute to that risk.

Women tend to be older at hospitalization for acute heart attack.
