Monitoring/adjunctive medical therapy

Continuous cardiac monitoring

Serial 12-lead ECG every 15–30 minutes for the first hour

Serial serum troponin measurement (every 1–6 hours)

Oxygen therapy for patients with:

• Cyanosis

• Severe dyspnea

• SpO2 < 90%

Fluid management:

• Intravenous fluids (e.g., normal saline)

  • Consider for inferior myocardial infarction causing RV dysfunction

  • Increasing the preload optimizes left and right ventricular filling and reduces hemodynamic instability.

• Loop diuretic (e.g., furosemide): consider for patients with pulmonary edema, acute heart failure
