Question

A young patient has angina at rest with ST-segment elevation. Cardiac enzymes are normal. What is the most likely diagnosis?

1) Myocardial infarction
2) Unstable angina
3) Stable angina
4) Prinzmetal's angina

Answer 1

The most likely diagnosis for a young patient with angina at rest with ST-segment elevation and normal cardiac enzymes is Prinzmetal's angina.

Step-by-step explanation:

The most likely diagnosis for a young patient with angina at rest with ST-segment elevation and normal cardiac enzymes is Prinzmetal's angina. Prinzmetal's angina, also known as variant angina, is a type of angina that occurs due to spontaneous vasospasm of the coronary arteries. Unlike stable angina that is typically brought on by exertion, Prinzmetal's angina can occur at rest.

Patients with Prinzmetal's angina may experience ST-segment elevation on an electrocardiogram (ECG) during an episode of angina. However, unlike a myocardial infarction (MI), the levels of cardiac enzymes such as creatine kinase MB and cardiac troponin will be normal.

It is important to seek medical attention for a proper diagnosis and management of Prinzmetal's angina.
