Is the Left Ventricular Dysfunction a Heart Attack?

The patient's echocardiogram showed that the left ventricle was really not working well. A chest x-ray revealed that the lungs were clear and a CT scan of the head found no evidence of a stroke or bleeding in the brain. His blood work showed that his markers for liver injury were slightly elevated but not too out of the ordinary. The troponin measurement may suggest that active injury is happening to the heart.
