What's the youngest age you can be to have a cardiac arrest from an overdose? - cardiac arrest condition_symptoms

How can a young age have a heart for them, because I'm 15 and I accidentally overdosed on my Proventil inhaler. My friend told me that the worst thing that could happen, that it could be a heart attack. Could you just at my age of an overdose? I'm not worried, I am, I am curious, if possible.
