1-year Target Vessel Revascularization after PCI
Risk Calculator

This tool calculates the predicted risk of target vessel revascularization in patients undergoing percutaneous coronary intervention (PCI). The expected risk can be calculated based on the use of either a drug-eluting or bare metal stent.

To compute the predicted risk of 1-year target vessel revascularization after PCI, select the appropriate age and risk factors, then click the Calculate button at the bottom of the page. Upon opening or resetting the form, all fields will have default values set (# of Lesionse=1, all others=No). If errors are generated, then all values will be reset to default.

Disclaimer:

This risk calculator should be used for informational purposes only. If you have questions or concerns about the risk factor results, please consult with your health care doctor or cardiac care specialist. The computation is based on data from all Massachusetts hospitals, and is not specific to any one hospital.

Risk adjustment is a statistical process used to account for differences in patient sickness prior to their surgery. By entering the values for each risk factor for a single patient, you can get an estimated risk of mortality value for that patient prior to surgery. The final risk value will be between 0%, the lowest risk of a mortality, and 100%, the highest risk of mortality.
