Introduction

When patients with end-stage liver disease undergo orthotopic liver transplantation, coronary artery disease (CAD) is linked with considerable morbidity and death. This cohort's prevalence of CAD is comparable to, if not higher than, that of the overall population. Numerous studies suggest a low threshold for PCI in patients with obstructive CAD because they indicate increased survival rates for those who receive the procedure. A few studies, meanwhile, have not been able to demonstrate reduced mortality linked to PCI in this sample. This study aims to discuss the results of PCIs and to emphasise the current recommendations for the evaluation of CAD in patients with endstage liver disease who are candidates for orthotopic liver transplantation [1].

Description

Acute-on-chronic liver failure can be cured through liver transplantation (LT) (ACLF). However, in end-stage liver illness, malnutrition and multiple organ failure appear to lower cardiopulmonary reserve function and physical activity (ESLD). It might be difficult to deal with the adverse postoperative results of the lengthy LT operation. Rehabilitation has been frequently used in cases of severe surgery and liver illness. In some groups, it shortens hospital stays or intensive care unit (ICU) stays and lowers the incidence of readmission. As it relates to the perioperative care in LT, this setting might also be investigated. Therefore, it is crucial to quickly come to an agreement on how to assess and carry out therapy in LT patients with ACLF [2].

A quick way to check for malnutrition in patients who are asleep, under the influence of drugs, or have poor cardiopulmonary function is to measure the circumference of the muscles in the middle of their arms (MAMC). Adult males and females had conventional MAMC measurements of 25.3 and 23.2 cm, respectively. To evaluate the nutritional status of patients with liver disease, the Subjective Global Assessment (SGA) and Royal Free Hospital-Global Assessment procedures, which are based on MAMC and food intake, are frequently employed [3]. The objective measurement of muscle mass is done using ultrasound, computed tomography, or magnetic resonance imaging. Ultrasound is a simple, affordable and non-invasive way to assess muscle thickness and pennation angle of muscle fibre. Its repeatability, however, needs more investigation. The dietary status of critically sick patients is independently linked with the third lumbar vertebrae skeletal muscle index (L3-SMI) on CT. Males with a SMI of less than 42 cm²/m² and females with a SMI of less than 38 cm²/m² can be diagnosed with sarcopenia. SMI in LT patients is related to transplant outcome and can be utilised to assess the effectiveness of physical therapy interventions dynamically [4].

The aerobic exercise endurance test is the most popular way of evaluating physical activity for aware patients who can cooperate and walk without the use of any equipment. The 6MWT is a quick instrument to evaluate physical performance both before and after LT, in addition to its general usage in the heart and lungs. The postoperative quality of life and survival during the time preceding surgery are highly connected with the 6MWT. Preoperative 6MWT 250 m is substantially linked with mortality, improving short-term survival by 50% for every 100 m over baseline. The 6MWT is strongly and favourably connected with surgical complications or survival quality outcomes both preoperatively and postoperatively. A score of 0–6 on the short physical performance test denotes insufficient muscle function, 7-9 points denotes moderate muscle function and 10–12 points denotes good muscular function. Many ACLF patients have recently employed the liver frailty index (LFI), which measures balance, grip strength and ability to rise up from a chair. A 4.5 means that you are feeble. The outcome of liver transplant recipients may be accurately predicted using preoperative and postoperative LFIs, which can also be used to direct rehabilitation care. Additionally, a few integrated evaluation measures, such the Karnofsky performance scale and the activities of daily life scale, can be used as instruments to merely assess physical function [5].

Conclusion

It is conceivable to conduct a randomised investigation of GDFT after liver transplantation. Following the experiment, a stakeholder meeting encouraged moving on with a complete multi-center trial.
