Elective coronary angiography

---had a low yield in this large data base:

Conclusions: In this study, slightly more than one third of patients without known disease who underwent elective cardiac catheterization had obstructive coronary artery disease. Better strategies for risk stratification are needed to inform decisions and to increase the diagnostic yield of cardiac catheterization in routine clinical practice.

So about a third of patients had potential revascularization targets. Of those, many were likely more appropriate for medical management.
