Study Notes
NSTEMI Management
- High-intensity statin therapy using atorvastatin or rosuvastatin should commence regardless of LDL cholesterol levels.
- Baseline and follow-up liver function tests are necessary for patients on statins, alongside monitoring for muscle pain.
- Antiplatelet therapy with aspirin and a P2Y12 receptor blocker is crucial for all NSTEMI patients, initiated at diagnosis.
- Monitor for excessive dosages of antithrombotic and antiplatelet agents to mitigate bleeding risk.
Electrolyte Management
- Maintaining potassium levels above 4 and magnesium levels above 2 may provide patient benefits; hence, electrolyte repletion is suggested as needed.
Arrhythmia Management
- NSTEMI patients face increased risks for atrial and ventricular arrhythmias, necessitating proactive arrhythmia management to prevent hypoperfusion and death.
Risk Stratification
- Early risk stratification is essential for identifying patients with acute coronary syndromes who may require aggressive therapy.
- The HEART score is a popular tool for risk assessment in emergency department settings.
Treatment Strategies for NSTEMI
- Initial strategies include administering oxygen, aspirin, and nitrates based on suspicion of ACS, even before a definitive diagnosis is established.
- Confirming diagnosis dictates subsequent management; aggressive reperfusion strategies are prioritized for STEMI patients to restore blood flow quickly.
Percutaneous Coronary Intervention (PCI)
- PCI involves arterial access (radial or femoral), diagnostic angiography, and potential interventions like stenting or thrombectomy for occluded coronary arteries.
- Angiography may reveal both acute and chronic lesions; immediate PCI often targets culprit lesions in multivessel or left main coronary artery disease cases.
Fibrinolysis
- If PCI is unachievable within 120 minutes of contact, fibrinolytic therapy should be initiated within 30 minutes of hospital arrival.
- Choice of P2Y12 inhibitor differs based on treatment type; ticagrelor and prasugrel are preferred post-PCI, while clopidogrel is for fibrinolytic therapy candidates.
Life-Threatening Conditions Evaluation
- Initial STEMI assessment should include evaluation for urgent conditions like shock, heart failure, aortic dissection, and coagulopathy.
- Signs of cardiogenic or distributive shock include cool extremities and jugular venous distension; specific management for shock is critical.
- Symptoms of heart failure such as orthopnea and pulmonary edema must be evaluated.
Aortic Dissection Consideration
- Symptoms of aortic dissection, including severe chest/back pain and asymmetric upper extremity pulses, necessitate distinct management strategies from typical STEMI treatment.
Initial Management Priorities
- Rapid selection and administration of reperfusion therapy are vital for STEMI management.
- Treatments should aim to prevent further coronary thrombosis, minimize myocardial injury, and alleviate myocardial infarction symptoms.

Description
This quiz covers the management of patients with Non-ST-Elevation Myocardial Infarction (NSTEMI), focusing on high-intensity statin therapy and antiplatelet therapy. It outlines the protocols for prescribing Atorvastatin or Rosuvastatin regardless of cholesterol levels and emphasizes the importance of monitoring liver function and muscle pain. Test your knowledge on these critical treatment guidelines.
