FAQ
Frequently Asked Questions
No, it is a sign or symptom of an underlying condition affecting the heart, such as high blood pressure, heart valve problems, or cardiomyopathy.
Sometimes, if the underlying cause is treated effectively (e.g., controlling hypertension), the heart may reduce in size, but this depends on the specific cause and severity.
They mean the same thing. 'Cardiomegaly' is the formal medical term, while 'enlarged heart' is the layperson's term.
It is typically first suspected on a chest X-ray and then confirmed and measured more accurately using an echocardiogram (heart ultrasound) or other imaging like a CT or MRI scan.
