title: Unstable angina pectoris: therapeutic choices.
abstract: 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.
