Prognosis and Medical Cost of Measuring Fractional Flow Reserve in Percutaneous Coronary Intervention.

ABSTRACT:

Background

There are limited data regarding comparative prognosis and medical cost between fractional flow reserve (FFR)-based and angiography-based percutaneous coronary intervention (PCI) among revascularized patients.

Objectives

This study evaluates prognosis and medical cost of FFR use in revascularized patients by PCI.

Methods

Using the National Health Insurance Service database, stable or unstable angina patients who underwent PCI from 2011 to 2017 were evaluated. Eligible patients were divided into 2 groups according to use of FFR in PCI. Primary outcome was a composite of all-cause death or spontaneous myocardial infarction (MI). Secondary outcomes included individual components of the primary outcome, unplanned revascularization, and medical costs.
