Cardiac Risk Index
The Vascular Study Group of New England developed an algorithm to predict the likelihood of post-operative myocardial infarction, congestive heart failure, or arrhythmia requiring treatment. The Vascular Study Group Cardiac Risk Index (VSG-CI) applies to carotid endarterectomy, lower extremity bypass, and endovascular and open repair of non-ruptured abdominal aortic aneurysms. Unlike most other cardiac risk predictors, this was developed in a cohort of 8,000 vascular patients and validated in a cohort of 1,800 patients. This process revealed that typical vascular patients had a higher predicted rate of cardiac complications than would be predicted by other available risk models. Details are contained in the following publication:
