Cardiac syndrome X is a term that describes the association of typical oppressive chest pain, ST segment depression during exercise, and normal coronaries on angiography. It’s attributed in most cases to change in coronary microvasculature.

As it is currently known that normal coronaries on angiography are required to diagnose cardiac syndrome X. In the following article, the first cardiac syndrome X to be diagnosed by stress echocardiogram is reported. A coronary angiography done few days later, confirmed the diagnosis.
