Patients at high risk for ischemic complications.
The identification of the factors which predict increased risk for procedural complications in patients undergoing percutaneous revascularization allows a prospective stratification and evaluation of the risk benefit ratio in the individual patient. Such stratification may allow choice of other management options, such as medical therapy or bypass surgery, but probably more importantly allows the selective application of adjunctive pharmacotherapy or mechanical support techniques. It is important to recognize the limitations of all pre-procedural risk assessment however in that overall these criteria still have relatively low predictive value and to a great extent closure remains unforeseeable. Additionally, high risk characteristics are frequently encountered in clinical practice, and for many high risk patients the best option for revascularization may still be the percutaneous one.
