Transient Cardiac Dysfunction Following a Cerebrovascular Accident.

Area of Science:

• Neurocardiology
• Neurology
• Cardiology

Background:

• Acute cerebral injuries frequently cause electrocardiogram (ECG) abnormalities, including arrhythmias and T-wave changes.
• Cerebral T-waves are a rare, specific ECG phenomenon characterized by transient, symmetric, deeply inverted T-waves in precordial leads, often associated with acute ischemic stroke.

Observation:

• A patient presented with symptoms suggestive of an ischemic cardiac event: acute pulmonary edema, precordial T-wave inversions, and left ventricular dysfunction.
• Initial cardiac workup raised suspicion for myocardial infarction, but subsequent brain imaging revealed an acute cerebral injury.

Findings:

• The patient's presentation mimicked a primary cardiac event, but the underlying cause was a neurological deficit.
• This case underscores the potential for cerebral T-waves to be misdiagnosed as primary cardiac ischemia.

Implications:

• Recognizing cerebral T-waves is crucial for accurate diagnosis and appropriate management of patients with acute neurological events.
• This phenomenon highlights the complex interplay between the brain and the heart, emphasizing the need for a comprehensive diagnostic approach.
