Concordance of Preoperative Clinical Risk With Angiographic Severity of Coronary Artery Disease in Patients Undergoing Vascular Surgery
Why the study?
Does a preoperative clinical index predict the angiographic severity of coronary artery disease in patients undergoing vascular surgery?
Population
878 consecutive patients undergoing vascular surgery

Implication
May identify low-risk vascular surgery patients unlikely to need angiography; leaves open prospective outcome validation before practice change.
Structured PICO
Does a preoperative clinical index predict the angiographic severity of coronary artery disease in patients undergoing vascular surgery?
P
Population
878 consecutive patients undergoing vascular surgery
I
Intervention
Preoperative clinical index assessment (evaluating history of diabetes mellitus, prior myocardial infarction, angina, age > 70 years, and congestive heart failure)
O
Outcome
Presence of severe or critical coronary stenosis on angiographysurrogate
A simple clinical index can reliably exclude severe or critical coronary artery disease in patients undergoing vascular surgery, potentially reducing the need for preoperative cardiac testing.
