 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:

Bertges DJ, Goodney PP, Zhao Y, Schanzer A, Nolan BW, Likosky DS, Eldrup-Jorgensen J, Cronenwett JL.: The Vascular Study Group of New England: Cardiac Risk Index (VSG-CRI) predicts cardiac complications more accurately than the Revised Cardiac Risk Index in vascular surgery patients.” Journal of Vascular Surgery 52.3 (Sept 2010): 674-83.

In order to make this practical in the clinical setting, VSGNE and SVS VQI have partnered with QxMD Software, a company dedicated to creating free, high quality, point-of-care tools for practicing health care professionals. You can access these tools by downloading the free smartphone app ‘Calculate by QxMD’ currently available for iPhone, iPad, or Android​ through the App Store or Android Market.
