Impact of frailty on outcomes following coronary artery bypass grafting: a systematic review and meta-analysis.

Background: Coronary artery bypass grafting (CABG) remains the preferred treatment for complex multi-vessel coronary artery disease, offering substantial long-term benefits. Non-cardiac comorbidities such as frailty may significantly affect the outcomes of this procedure. However, the exact impact of frailty on CABG outcomes remains unclear, particularly given its exclusion from many pivotal revascularization trials.

Prognostic nutritional index and prognosis of patients with coronary artery disease: A systematic review and meta-analysis.

Background: This review assessed if prognostic nutritional index (PNI) can predict mortality and major adverse cardiac events (MACE) in coronary artery disease (CAD) patients.

Methods: PubMed, Web of Science, Scopus, and Embase were searched up to 1st November 2022 for all types of studies reporting adjusted associations between PNI and mortality or MACE in CAD patients. A random-effect meta-analysis was conducted for PNI as categorical or continuous variable.
