Question

Quizplus · Accepted Answer

The presentation of chest pain in a patient with a history of stable angina that is now unstable suggests that the patient is likely experiencing an impending myocardial infarction. This is a serious and potentially life-threatening condition that requires immediate medical attention. Mild to moderate atherosclerosis, electrical conduction problems in the heart, and decreased myocardial oxygen demand may all contribute to the development of unstable angina, but they would not necessarily explain the sudden onset of chest pain in this patient.
