What is the optimal medical management for a patient with CAD s/p PCI with a drug-eluting stent, HTN, HLD, and recent NSTEMI with reduced LVEF and normal LDL levels?

Optimal Medical Management for Post-NSTEMI Patient with Reduced LVEF

This patient requires comprehensive guideline-directed medical therapy including dual antiplatelet therapy for 12 months, high-intensity statin (already at goal), beta-blocker, ACE inhibitor or ARB, and consideration for mineralocorticoid receptor antagonist given the reduced LVEF of 40-45%. 1

Antiplatelet Therapy

Continue dual antiplatelet therapy (DAPT) with aspirin plus a P2Y12 inhibitor for at least 12 months following drug-eluting stent placement for NSTEMI. 1

• Aspirin: Continue indefinitely at 81 mg daily (low-dose preferred over higher doses to minimize bleeding risk while maintaining efficacy) 1, 2
• P2Y12 Inhibitor: Continue for 12 months minimum after DES implantation 1
  • Clopidogrel 75 mg daily is appropriate if already established and tolerated 3
  • If not yet started or considering change, prasugrel (10 mg daily) or ticagrelor (90 mg twice daily) are preferred over clopidogrel for NSTEMI patients, though clopidogrel remains acceptable 1
  • The patient should not discontinue P2Y12 inhibitor therapy prematurely, as this significantly increases risk of stent thrombosis 4, 5

Heart Failure Medications for Reduced LVEF

Given LVEF of 40-45%, this patient requires neurohormonal blockade to reduce mortality and prevent heart failure progression. 1

ACE Inhibitor or ARB

• ACE inhibitor is recommended starting within the first 24 hours after NSTEMI in patients with reduced LVEF (<40-45%) 1
• If ACE inhibitor is not tolerated, substitute with ARB (preferably valsartan) 1
• Continue indefinitely for secondary prevention 1

Beta-Blocker

• Beta-blocker therapy should be initiated and continued indefinitely in all post-MI patients, particularly those with reduced LVEF 1
• Start within 24 hours if hemodynamically stable 1
• Titrate to target doses as tolerated 1

Mineralocorticoid Receptor Antagonist (MRA)

• MRA (spironolactone or eplerenone) is recommended for patients with LVEF ≤40% and heart failure or diabetes who are already receiving ACE inhibitor and beta-blocker 1
• Ensure no renal failure (creatinine >2.5 mg/dL in men, >2.0 mg/dL in women) or hyperkalemia before initiating 1
• Monitor serum potassium routinely after initiation 1

Lipid Management

Continue high-intensity statin therapy indefinitely; LDL at 51 mg/dL is at goal. 1, 6

• Current LDL of 51 mg/dL meets secondary prevention targets 6
• High-intensity statin (atorvastatin 40-80 mg or rosuvastatin 20-40 mg) should be continued 1
• Recheck fasting lipids periodically to ensure continued goal achievement 1

Blood Pressure Management

Optimize blood pressure control, particularly given history of hypertensive urgency at presentation (BP 215/131). 1

• Target blood pressure <130/80 mmHg for patients with CAD 1
• ACE inhibitor/ARB and beta-blocker will contribute to BP control 1
• Add additional antihypertensive agents as needed to achieve target 1

Additional Considerations

Proton Pump Inhibitor

• Consider PPI for gastrointestinal protection in patients on DAPT, especially those at high risk for GI bleeding 1, 2
• Risk factors include: age >65, history of GI bleeding, concurrent anticoagulation, or NSAID use 1

Cardiac Rehabilitation

• Participation in cardiac rehabilitation program is recommended to improve outcomes 6
• Patient is already walking a mile daily, which is encouraging for exercise capacity 6

Monitoring and Follow-up

• Repeat echocardiogram in 3-6 months to reassess LVEF after optimal medical therapy 1
• Monitor renal function and electrolytes, especially if MRA is initiated 1
• Assess for symptoms of heart failure at each visit 1

Management of Non-Culprit Lesions

The 50% mid-LAD and 30% mid-distal RCA stenoses represent non-culprit lesions that were appropriately managed conservatively at the time of PCI. 1, 6

• These lesions do not require immediate revascularization given they are not flow-limiting 1
• Continue optimal medical therapy for secondary prevention 6
• Consider stress testing if symptoms develop or at appropriate intervals for risk stratification 1

Critical Pitfalls to Avoid

• Never discontinue DAPT prematurely before 12 months without consulting cardiology - this dramatically increases stent thrombosis risk 1, 4, 5
• Do not delay initiation of ACE inhibitor and beta-blocker - early initiation improves mortality in reduced LVEF 1
• Avoid NSAIDs - increase bleeding risk with DAPT and can worsen heart failure 1, 2
• Monitor for hyperkalemia if MRA is added, especially with concurrent ACE inhibitor/ARB 1
• If noncardiac surgery is needed, delay until 12 months post-stent if possible to allow completion of DAPT course 2
