Management of Metoprolol in Patients with Low Systolic Blood Pressure

Introduction to Metoprolol Management

The American College of Cardiology recommends holding beta-blockers when systolic blood pressure drops below threshold values, with an adjusted odds ratio for death and stroke of 4.97 (95% CI 3.62 to 6.81) in patients with clinically significant hypotension on beta-blockers 1
In perioperative settings, the American Heart Association suggests holding beta-blocker medication if systolic blood pressure is below 100 mmHg, based on clinical trials 1, 2

The American College of Cardiology advises monitoring blood pressure before each dose, holding metoprolol dose if SBP < 90 mmHg, and using caution if SBP is 90-100 mmHg 1, 4
The American Heart Association recommends monitoring additional parameters, including heart rate, holding metoprolol if heart rate < 50 bpm, and signs of heart failure 1, 4, 5
In cases of cardiogenic shock, metoprolol is absolutely contraindicated, according to the American College of Cardiology 3, 5

For patients with acute coronary syndromes, the American Heart Association suggests initiating oral beta-blocker therapy within 24 hours only in patients without signs of heart failure, low-output state, or increased risk for cardiogenic shock 5
In the perioperative setting, the American College of Cardiology notes that hypotension and bradycardia from beta-blockers are associated with increased mortality and stroke risk, requiring close monitoring of hemodynamic parameters 1, 2
The American Heart Association recommends considering alternative causes of tachycardia, such as sepsis or hypovolemia, before resuming beta-blocker therapy in patients with persistent tachycardia despite hypotension 1

The American College of Cardiology advises avoiding abrupt long-term discontinuation of beta-blockers in patients chronically taking them, as this can lead to rebound effects, and instead recommends reassessing blood pressure after 2-4 hours and investigating potential causes of hypotension 1, 3, 4
Continuing beta-blockers despite persistent hypotension can lead to tissue hypoperfusion, organ dysfunction, and increased mortality, according to the American Heart Association 1, 2
