Cardiomegaly is a frequent finding on chest X-ray. However, it is important to understand that a CXR does not visualize the heart muscle directly but instead interprets its shadow. As an indirect measurement, this finding is not definitive.
Several technical and anatomical factors can affect the appearance of the heart's size on an X-ray. These include an individual's body habitus, the phase of respiration during the image, and the specific projection used to take the X-ray.
If your chest X-ray report notes cardiomegaly, it is important to follow up with a cardiologist for a complete evaluation. The next steps usually involve tests like an EKG and an echocardiogram (a heart ultrasound) to get a clear picture of your heart's health and understand the reason behind the X-ray finding.
