Method and apparatus for perioperative assessment of cardiovascular risk
First Claim
1. A method of assessing a patient'"'"'s cardiovascular risk, the method comprising the acts of:
- acquiring an electrocardiogram for the patient;
assigning a first diagnostic statement of minor cardiovascular risk to the acquired electrocardiogram if the acquired electrocardiogram exhibits a non-life-threatening cardiac condition;
performing a serial comparison between the acquired electrocardiogram and a previous electrocardiogram;
determining whether the non-life-threatening cardiac condition exhibited in the acquired electrocardiogram was exhibited in the previous electrocardiogram;
assigning a second diagnostic statement of major cardiovascular risk to the acquired electrocardiogram if the cardiac condition was not exhibited in the previous electrocardiogram;
determining a probability of cardiovascular risk value based on the second diagnostic statement; and
displaying the probability of cardiovascular risk value to a clinician.

Abstract
A method and apparatus for providing real-time support in interpreting a patient'"'"'s ECG in order to assess the probability of perioperative cardiovascular risk associated with performing a non-cardiac surgery. The apparatus includes an acquisition unit for acquiring an ECG and a processor for determining whether the ECG has diagnostic statements of risk. From the diagnostic statements of risk, the processor determines the probability of cardiovascular risk associated with the non-cardiac surgery. The probability of cardiovascular risk is displayed on display in the form of an indicator of either major, intermediate, or minor cardiovascular risk.
The method includes acquiring a patient'"'"'s ECG, determining whether the ECG exhibits diagnostic statements of cardiovascular risk, and determining the probability of cardiovascular risk based on the diagnostic statements, and displaying the determined probability of cardiovascular risk.
