Hi Welcome to Healthcare magic,
I understand your query and concern.
The diagnosis could be Cardiomegaly or
Dilated cardiomyopathy.
I advise you to get a 2 Dimensional Echo cardiography of your heart immediately to confirm the diagnosis.
A routine ECG,
lipid profile ,chest x ray will help for evaluation.
Once the diagnosis is confirmed,depending on heart parameters like
Ejection fraction,blood pressure,heart rate the treatment options can be framed out.
Avoid strenuous activities.
Avoid smoking or alcoholo if any,
Report to emergency if you have symptoms like
Shortness of breath,chest pain or dizziness.
Consult your cardiologist for expert management.
Post your further queries if any,
Thank you.
