Which finding is commonly seen in dilated cardiomyopathy on presentation?

• A. Lateralized apex beat
• B. Orthopnea
• C. Enlarged cardiac silhouette on chest X-ray
• D. S3 heart sound

Answer: (C)

Dilated cardiomyopathy causes dilation of the heart chambers, especially the left ventricle, with reduced pump function. This volume overload and remodeling lead to a larger heart that is often visible as an enlarged cardiac silhouette on a chest X-ray. It’s a common and characteristic imaging finding when patients present with this condition. While a displaced apical impulse can occur from LV dilation and symptoms like orthopnea or a soft S3 can accompany heart failure, the chest X-ray showing an enlarged heart best reflects the typical presentation of dilated cardiomyopathy.
