Coronary artery bypass grafting with or without preoperative physiological stenosis assessment: a SWEDEHEART study.

ABSTRACT:

Background and aims

Physiological flow assessment of coronary stenoses, such as fractional flow reserve, are routinely used to guide percutaneous coronary intervention, but it has not been equally recognized to guide coronary artery bypass grafting (CABG). Mid-term outcomes in CABG patients with and without preoperative flow assessment were compared.

Methods

All patients with first-time isolated CABG in Sweden 2013-2020 were identified in the SWEDEHEART registry (n = 18 211), which also provided information on flow assessment. Data were linked with three mandatory national registries. Median follow-up was 3.6 years (range 0-7.5). Incidence of all-cause mortality, stroke, new myocardial infarction, new coronary angiography, and new revascularization was compared using adjuste
