First of all it is very unlikely that a 17 year old girl would be having a
heart attack unless there is a history of
sudden cardiac death at a young age (meaning someone in her family dropping dead suddenly without an apparent reason) or history of premature coronary artery disease or congenital coronary artery disease (such as an anomalous coronary artery).
It sounds like your symptoms can be attributed to you running in the cold. I'm assuming you don't have any other significant medical problems, such as
diabetes or
dyslipidemia (
high cholesterol). You should still get this checked out by your doctor, particularly if this is a frequent occurrence.
To the poster who suggested an angiogram, that is definitely not indicated at this time. There are other less invasive tests that can be done first (if even needed in her case). An angiogram is a routine test that is done in patients everyday, but it is not without risks and should only be done if truly indicated. There are very few reasons for a 17 year old to have a coronary angiogram.
