Key result
Clinical criteria for unstable angina effectively direct medical optimization and timing of surgical intervention.
Why the study?
Unstable angina involves a progressive process with potential for acute emergence, requiring criteria for monitoring severity and guiding therapy decisions.
Key points are not available for this paper at this time.
Design
Other
Proposed criteria for unstable angina monitoring and intervention decisions warrant cautious use; leaves open prospective validation in contemporary cohorts.
Unstable angina by definition involves a progressive process that has the potential for becoming acutely emergent. The authors offer criteria for monitoring the severity of the process, for designing medical therapy, and for making critical decisions with respect to turning from medical management to surgical intervention, either on an elective or an emergency basis.
