dilated LV (left ventricular diastolic diameter)

[bevo9]

I'm 21, and I've been having chest pains, so I went to the Dr. ended up getting an echocardiogram. It showed that the left ventricle in my heart was dilated (57mm). The Dr. told me to stop drinking, smoking (cigarettes), vyvanse/adderall, and cut back on caffeinated beverages. I'm in college and I've been finding it hard to stop all of these cold turkey, and I'm a bit worried about how much of a concern this condition can be? (Is this considered cardiomyopathy or not?) He told me it can lead to congestive heart failure if I continue to use all these substances.

I've tried to research the normal size of the LV and most articles I've found say I'm in the normal range (with 57mm being the very high end of normal).

Any info/input would be of help, thank you!

You doctor is right that dilation of the LV can lead to heart failure.
It is of importance that this dilation does not worsen and even better, that the ventricle gets back to its normal size.

Often, the dilation is a result form a prolonged period of high blood pressure.
What is your current blood pressure?
Drinking, smoking, vyvance do not have a direct effect on the LV but as they increase bp, they have an indirect effect.
If they increase your blood pressure to an unhealthy level, you need to at least try to cut back (if completely stopping is not an option) .

My blood pressure has been normal for the most part, except when I take adderall/vyvanse.
