Fasting Versus Non-fasting Protocols Before Cardiac Catheterization Procedures: A Meta-analysis of Clinical Trials.

ABSTRACT:

Background

Recent trials suggest that liberalizing oral intake prior to cardiac catheterization procedures improves patient satisfaction and is as safe as the traditional practice of "nothing by mouth." We aimed to compare the outcomes of fasting and nonfasting protocols before such procedures.

Methods

We searched PubMed and Cochrane Library until May 1, 2025, for clinical trials comparing fasting and nonfasting protocols for a variety of cardiac catheterization procedures. Outcomes of interest were all-cause mortality, aspiration, hypoglycemia, hyperglycemia, nausea/vomiting, contrast-induced nephropathy, and hypotension. Risk ratios (RR) with 95% CI were calculated using the inverse variance method, and quality was assessed using the Cochrane Risk of Bias 2.0 tool.
