Hi,
I am a cardiologist in Turkey.
On most of chest X-Ray's were seen mild cardiomegaly, especially in obesity. Echocardiography is necessary to show true cardiomegaly.
In my opinion you should have an echocardiographic examination.
Have a nice day!

The chest xray means that your heart is mildly enlarged. The xray alone does not allow any definitive conclusion as to the cause of the enlargement. Common causes include long-standing high blood pressure, which is most likely in your case. Other causes of cardiac enlargement include valvular heart disease or congestive heart failure, though there does not appear to be any associated indication of these other conditions on the the xray.
