Zorluk: KolayPharmacologic Interventions

A 55-year-old woman is preparing for discharge following an admission for a non-ST-segment elevation myocardial infarction (NSTEMI). She underwent a successful percutaneous coronary intervention with the placement of a drug-eluting stent. Her past medical history includes hypertension and hyperlipidemia. Her vitals are temperature 37.0∘C37.0^\circ\text{C} (98.6∘F98.6^\circ\text{F}), blood pressure 122/78 mmHg122/78\text{ mmHg}, pulse 68/min68/\text{min}, and respiratory rate 14/min14/\text{min}. An echocardiogram demonstrates a left ventricular ejection fraction of 55%55\%. In addition to dual antiplatelet therapy with aspirin and clopidogrel, which of the following pharmacologic interventions should be included in her discharge regimen to provide a long-term mortality benefit? (Select all that apply)

  1. AtorvastatinCevap
  2. MetoprololCevap
  3. C
    Ibuprofen
  4. D
    Flecainide
  5. E
    Rivaroxaban

Cevap

The correct interventions are Atorvastatin and Metoprolol.
Both high-intensity statins (like atorvastatin) and beta-blockers (like metoprolol) are foundational secondary prevention therapies following an acute coronary syndrome. Statins stabilize atherosclerotic plaques and reduce the risk of recurrent cardiovascular events, while beta-blockers decrease myocardial oxygen demand, inhibit adverse cardiac remodeling, and reduce the risk of fatal arrhythmias, collectively conferring a significant mortality benefit.

Adım Adım Çözüm

1
Identify the patient's clinical scenario.
The patient is being discharged after an uncomplicated NSTEMI and successful PCI, with a preserved ejection fraction.
Establishing the phase of care (secondary prevention) dictates the appropriate pharmacologic management.
2
Determine which medications provide a long-term mortality benefit for secondary prevention after acute coronary syndrome.
Dual antiplatelet therapy, beta-blockers, high-intensity statins, and ACE inhibitors (especially in patients with diabetes, anterior MI, or reduced ejection fraction) are the pillars of secondary prevention.
These medication classes act through different mechanisms to prevent recurrent ischemia, plaque rupture, and fatal arrhythmias.
3
Evaluate the given options to select those indicated while excluding contraindicated agents.
Atorvastatin and Metoprolol are indicated. Ibuprofen and Flecainide are absolutely contraindicated post-MI. Rivaroxaban is inappropriate as it causes excessive bleeding risk when combined with DAPT without a separate indication.
Appropriate patient management requires recognizing both life-saving therapies and dangerous drug contraindications.

Anahtar Kavram

Secondary pharmacologic prevention following an acute coronary syndrome requires a beta-blocker, a high-intensity statin, and dual antiplatelet therapy to optimize long-term mortality outcomes.
