Which combination of findings best supports NSTEMI rather than STEMI or unstable angina?

A
A troponin value above the reference limit alone, with no evidence of ischemia.
B
A rise or fall in troponin with at least one value above the assay's 99th-percentile limit, in an ischemic clinical context, without persistent diagnostic ST elevation.
C
Persistent diagnostic ST elevation, whether or not the clinical presentation suggests ischemia.
D
No acute troponin pattern meeting MI criteria, with new or worsening angina.

A patient being evaluated for NSTEMI has recurrent ischemia and becomes hemodynamically unstable. Which next step is most consistent with the recommended approach?

A
Routine fibrinolysis for any recurrent chest discomfort.
B
Deferring further assessment until troponin becomes positive.
C
Urgent assessment for invasive management.
D
Discharge without further evaluation if the initial ECG was nondiagnostic.

A patient's ECG and clinical presentation indicate STEMI, but the initial troponin result is not yet available. What is the appropriate principle for reperfusion assessment?

A
Wait for a positive troponin before assessing for reperfusion.
B
Assess for reperfusion immediately; do not let troponin testing delay indicated care.
C
Use fibrinolysis whether or not the patient is eligible.
D
Manage as unstable angina until serial troponin results are available.

A patient is told that their acute coronary syndrome is classified as NSTEMI. Which interpretation of this classification is most accurate?

A
An NSTEMI classification guarantees that the affected coronary artery is only partially blocked.
B
An NSTEMI classification describes a clinical pattern and does not, by itself, establish how completely an artery is blocked.
C
An NSTEMI classification means there is no coronary artery blockage.
D
An NSTEMI classification guarantees that the affected coronary artery is completely blocked.
