Key result
Increased regional rates of cardiac catheterization were associated with a linearly increasing yield of high-risk CAD, identifying 1 additional case per 2.5 (men) and 3.7 (women) procedures.
Why the study?
Does a higher population rate of cardiac catheterization improve the yield of high-risk coronary artery disease detection in the general population?
Population
All patients undergoing cardiac catheterization in Alberta's 17 health regions from 1995 to 2002

May support higher catheterization rates in low-utilization regions; leaves open need for prospective trials before practice change.

Effect estimate: 1 additional case per 2.5 procedures (men) and 3.7 procedures (women)
Higher regional rates of cardiac catheterization are associated with a linearly increasing yield of high-risk CAD without a plateau, suggesting current rates may be too low to detect all high-risk patients.
Michael M. Graham (2005) conducted an observational in High-risk coronary artery disease (CAD). Cardiac catheterization rate was evaluated on Yield of high-risk coronary artery disease (1 additional case per 2.5 procedures (men) and 3.7 procedures (women)). Increased regional rates of cardiac catheterization were associated with a linearly increasing yield of high-risk CAD, identifying 1 additional case per 2.5 (men) and 3.7 (women) procedures.
