Coronary events in patients undergoing orthotopic liver transplantation: perioperative evaluation and management

Area of Science:

• Cardiology
• Hepatology
• Transplant Surgery

Background:

• Patients with advanced liver disease often have co-existing cardiac risk factors.
• Liver transplant surgery imposes significant physiological stress, increasing the risk of major cardiac events.
• Perioperative cardiac events in liver transplant recipients are associated with reduced long-term survival.

Purpose of the Study:

• To highlight the importance of cardiovascular risk assessment and management in patients before liver transplantation.
• To review methods for cardiovascular risk stratification and intervention in the pre-transplant setting.

Main Methods:

• Cardiovascular risk stratification utilizing dobutamine stress echocardiography, stress myocardial perfusion imaging, cardiac computed tomography, and coronary angiography.
• Management strategies including percutaneous coronary intervention, coronary bypass graft surgery, and medical therapy for cardiovascular pathology.

Main Results:

• Pre-transplant cardiovascular evaluation can identify patients at high risk for perioperative cardiac events.
• Interventions to manage cardiovascular disease and risk factors can potentially mitigate adverse cardiac outcomes.
• Optimal pre-transplant cardiovascular care is essential for improving outcomes in liver transplant recipients.

Conclusions:

• Comprehensive cardiovascular screening and management are vital for liver transplant candidates.
• Addressing cardiovascular pathology and risk factors pre-transplant can decrease the incidence of cardiac events post-transplant.
• Proactive cardiovascular care improves survival rates for liver transplant recipients.
