[|Human|] I was recently diagnosed with a enlarged heart  left ventricle. Lung pressure is normal . Went for a sleep study I was negative for a sleep disorder but they they found I was having premature atrial contraction. Is there a connection between the two and what does this mean for me.
[|AI|]  Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. Heart enlargement can come from different reasons. Heart chamber might enlarge because of hypertension, ischemic heart disease, heart valve pathologies, arrhythmia, from genetic disorders, systemic disease, alcohol consumption, infections. Sometimes heart enlargement doesn't have any identifiable cause, called idiopathic cases. An enlarged heart might experience rhythm disorders, like premature heart contraction. In your case, the most important think is to find the reason of heart enlargement, this will help to know how to treat it. If I was your treating doctor I will recommend a good cardiac echo, a full blood analyze, cardiac enzymes' ect. Finding the etiology helps to treat it. Hope I was helpful. Bestregards, Chat Doctor.
