Why do women with a heart attack but no chest pain die so often?

Number of reasons. Mortality from heart attacks is related to age. Women develop heart disease, on average, 10 years later than men. Women are more likely to present with atypical symptoms that are not recognized either by the patient or the physician. This can result in a delayed diagnosis or missed diagnosis.
Atypical symptoms. Likely because symptoms aren't typical and aren't recognized early enough by patient or medical provider for effective intervention.
Do they? Your question implies that their condition goes unrecognized and, perhaps, there is some truth to that. Women's presentation is sometimes atypical and harder to spot. Also women's mortality from heart attack is statistically a little higher than men, but the reasons are complex and there isn't space here to fully review them.

29 yr old female. Have been experiencing chest pain radiating into left arm, neck and back for almost a month. Could a Heart attack be coming?

Possible, See Doctor. Your age (29) argues against an impending heart attack. Most heart attacks are unpredictable, & don't last 1 month in the making (that would be unstable angina, which is seen in the elderly). In any case, you should see a doctor in the clinic soon. Waiting 1 month w/ symptoms like this is not wise. Thanks for your question on HealthTap. Use HealthTap Prime or see your doctor soon. Read more...

I am a 29 year old female. I am healthy and work outregularly. I get a mild jaw pain that comes and goes. I haveno arm or chest pain. Could it be heart attack?

Unlikely. Jaw pain, especially if it occurs more in the morning can be due to biting down or grinding your teeth. It can also be produced by dental work that alters your bite, though the intermittency of your symptoms suggest things like teeth grinding or biting down from stress. Your heart does not share nerve supply for sensation of your jaw so heart attack unlikely. Also, it is very rare in a young woman. Read more...
Least likely. Although jaw pain can be a symptom of a heart attack, i think you would know by now if that was the problem. There are much more common causes of intermittent jaw pain. See a dentist for an evaluation of other common causes. Read more...
Need further testing. Jaw discomfort can be an atypical presentation of coronary heart disease, but further testing should be done before concluding that. A stress test, perhaps with echo or nuclear imaging, should be considered. Would be best to run this by your primary care physician. Read more...
