Unstable angina pectoris

Unstable angina pectoris is angina pectoris that can easily lead to acute myocardial infarction. Liver and kidney dysfunction can be diagnosed by blood tests. Acute myocardial infarction can also be diagnosed by elevated troponin in a blood test. Unfortunately, however, unstable angina is diagnosed by listening to the patient’s symptoms, not by blood tests. Unlike stable angina, the pattern of pain and pressure changes: the pain becomes more intense, the frequency of attacks increases, and even the slightest movement or resting state can cause an attack. Even so, it is difficult to make a diagnosis of angina pectoris. However, I believe that it is no use making a diagnosis of unstable angina if the result is wrong. On the other hand, if I fail to diagnose unstable angina and it turns out to be an acute myocardial infarction, it would be very serious.
