Treatment of hypertension in patients undergoing coronary artery by-pass grafting

Area of Science:

• Cardiology
• Anesthesiology
• Pharmacology

Background:

• Hypertension is highly prevalent in patients undergoing coronary artery bypass grafting (CABG), affecting up to 80% of this population.
• Managing pre-existing hypertension is crucial for optimizing outcomes in cardiac surgery patients.

Purpose of the Study:

• To provide guidance on the management of hypertension in patients scheduled for CABG.
• To outline strategies for maintaining hemodynamic stability during and after CABG in hypertensive patients.

Main Methods:

• Review of current guidelines and clinical practices for antihypertensive medication management in the perioperative setting of CABG.
• Emphasis on individualized patient monitoring and cautious titration of hypotensive therapy.

Main Results:

• Continuation of most antihypertensive medications is recommended until the day of surgery for hemodynamically stable patients.
• Aggressive blood pressure reduction during CABG is discouraged to prevent hemodynamic collapse.
• Beta-blockers should be administered to all CABG patients unless contraindicated.

Conclusions:

• Perioperative hypertension management in CABG requires a tailored approach, prioritizing hemodynamic stability over aggressive blood pressure lowering.
• Individualized monitoring and cautious initiation of hypotensive therapy with low dosages are essential.
• Universal administration of beta-blockers, where appropriate, is advised for CABG patients.
