Summary

Syndrome X, characterized by chest pain and normal coronary arteries, may stem from reduced blood vessel dilation. Some patients risk heart muscle enlargement, and effective treatments are currently lacking.

Area of Science:

  • Cardiology
  • Internal Medicine

Context:

  • Syndrome X lacks a precise clinical definition.
  • Patients present with effort angina and normal coronary arteries.
  • Exclusion of other chest pain causes is critical.

Purpose:

  • To define the characteristics of Syndrome X.
  • To explore potential pathophysiologic mechanisms.
  • To outline the prognosis and identify risk factors.

Summary:

  • Syndrome X involves chest pain with normal coronary arteries, possibly due to impaired vasodilation.
  • Prognosis is generally favorable.
  • A subset with left bundle branch block may develop dilated cardiomyopathy.

Impact:
