How is non-ST-segment elevation MI / unstable angina managed?

• A. Early invasive strategy: PCI or CABG.
• B. Immediate thrombolysis.
• C. Conservative medical management only.
• D. Lifestyle modification with no medications.

Answer: (A)

In NSTEMI and unstable angina, the approach is to risk-stratify patients and pursue definitive relief of ischemia when risk is not low. An early invasive strategy—bringing the patient to coronary angiography with the intention to revascularize by PCI or CABG as needed—is the preferred path for many patients because it directly addresses the problem: significant coronary disease that may cause ongoing or recurrent injury. Revascularization within the first day or two helps reduce the chance of death, recurrent MI, and ongoing chest pain in those at higher risk, while medical therapy alone may be insufficient in these cases. Immediate thrombolysis is not given here because there is no ST-segment elevation; thrombolytics work best for STEMI and carry bleeding risks without clear benefit in NSTEMI/unstable angina. Conservative medical management without planned revascularization is reserved for very low-risk patients; for most with NSTEMI/UA, combining antithrombotic and anti-ischemic therapy with consideration of early invasive care yields better outcomes. Lifestyle changes and medications alone cannot replace the need for timely revascularization when indicated.
