We aimed to quantify preoperative heart failure diagnostic accuracy and explore characteristics of patients with heart failure misdiagnoses.<h4>Methods</h4>We performed an observational cohort study of adults undergoing major noncardiac surgery at an academic hospital between 2015 and 2019. A preoperative clinical diagnosis of heart failure was defined using keywords from the history and clinical examination or administrative documentation. Across stratified subsamples of cases with and without clinically diagnosed heart failure, health records were intensively reviewed by an expert panel to develop an adjudicated heart failure reference standaBJA openPreoperative clinical diagnostic accuracy of heart failure among patients undergoing major noncardiac surgery: a single-centre prospective observational analysis.PMC9835767K01 HL141701Kheterpal SGolbus JRAaronson KDJoo HEngoren MCMaile MDMathis MRJanda AMCassidy RBMichigan Congestive Heart Failure InvestigatorsfalsePreoperative clinical diagnostic accuracy of heart failure among patients undergoing major noncardiac surgery: a single-centre prospective observational analysis.<h4>Background</h4>Reliable diagnosis of heart failure during preoperative evaluation is important for perioperative management and long-term care.
