Tako-tsubo cardiomyopathy, a stress-induced heart condition, was diagnosed in a woman presenting with chest pain. This condition mimics a heart attack but involves reversible left ventricular dysfunction.

Area of Science:

  • Cardiology
  • Internal Medicine
  • Medical Diagnostics

Background:

  • Tako-tsubo cardiomyopathy (TTC) is an acute cardiac syndrome.
  • It is characterized by transient left ventricular dysfunction.
  • Often triggered by emotional or physical stress.

Observation:

  • A 48-year-old woman presented with chest pain, ECG abnormalities, and hypotension.
  • Coronary angiography revealed normal coronary arteries.
  • Left ventriculography demonstrated apical ballooning, consistent with TTC.

Findings:

  • Echocardiography confirmed apical akinesis and basal hyperkinesis.
  • Ejection fraction was reduced to 35-40%.
  • Dynamic left ventricular outflow tract obstruction was observed.

Implications:

  • This case highlights the importance of considering TTC in patients with acute chest pain and normal coronaries.
  • Prompt diagnosis and management, including hemodynamic support, are crucial for recovery.
  • Understanding TTC's unique presentation aids in differentiating it from acute myocardial infarction.
