Rethinking False Positive Exercise Electrocardiographic Stress Tests by Assessing Coronary...

Exercise electrocardiographic stress testing (EST) has historically been validated against the demonstration of obstructive coronary artery disease. However, myocardial ischemia can occur because of coronary microvascular dysfunction (CMD) in the absence of obstructive coronary artery disease.

The aim of this study was to assess the specificity of EST to detect an ischemic substrate against the reference standard of coronary endothelium-independent and endothelium-dependent microvascular function in patients with angina with nonobstructive coronary arteries (ANOCA).

Charlotte’s story

While at work in September 2014, I lost vision of my left eye and had terrible feeling of “heat” all over the left side of my body.

The ER ophthalmologist directed me to cardiology for a vascular problem.

A week later, I could not walk 100 meters (325 feet) without crushing chest pain and shortness of breath.

I was no longer functional. Making my bed was all I could do in a whole day. I was no longer an active 54-year-old.
