Management of Metoprolol in Asymptomatic Patients

Blood Pressure Considerations

• Severe hypotension requiring intervention is defined as systolic BP <70 mmHg, according to emergency cardiovascular care guidelines, which is not met in this patient with a systolic pressure of 94 mmHg 1
• The American College of Cardiology identifies systolic BP <100 mmHg with symptoms as a threshold for holding metoprolol, but this patient is asymptomatic 2

Heart Rate Considerations

• Symptomatic bradycardia (HR <50-60 bpm with symptoms) is the contraindication, not asymptomatic bradycardia, as stated by the European Heart Journal and other guidelines 2, 3
• A heart rate of 72 bpm is well above the bradycardic threshold and represents normal sinus rhythm, according to the American College of Cardiology 2

Clinical Context and Monitoring

• The American Heart Association recommends monitoring blood pressure and heart rate at each visit during ongoing therapy, and watching specifically for development of symptomatic bradycardia (HR <60 bpm with dizziness or lightheadedness) 2
• The European Society of Cardiology suggests assessing for symptomatic hypotension (systolic BP <100 mmHg with symptoms like dizziness, lightheadedness, or blurred vision) 2

When to Hold Metoprolol

• The American College of Cardiology recommends holding the dose only if systolic BP <100 mmHg with symptoms (dizziness, lightheadedness, altered mental status, signs of hypoperfusion), or heart rate <50 bpm with symptoms (dizziness, lightheadedness, syncope) 2
• The American Heart Association suggests holding metoprolol if signs of decompensated heart failure develop, or evidence of high-grade AV block on ECG 2
