Results

A total of 5004 patients who underwent FFR measurement between 2010 and 2016 were enrolled and were followed until March 2020.
Of those, 2886 patients underwent revascularization after FFR measurements. During the follow up, 87 patients suffered from cardiac death and 59 patients suffered non-fatal myocardial infarction.

Baseline Characteristics

Among the patients enrolled in this study, 3728 (74.5%) were men, the average age was 69.7, 3783(75.6%) had chronic coronary syndrome, 659 (13.2%) had prior myocardial infarction, 421 (8.4%) had unstable angina, 118 (2.4%) had ST-segment elevated myocardial infarction, and 23 (0.5%) had non-ST-segment elevated myocardial infarction. 4026 (80.5) patients had hypertension, 3354 (67%) had dyslipidemia, 2098 (41.9%) had diabetes mellitus, 1268 (25.3%) had prior myocardial infarction, 462 (9.2%) had chronic kidney disease, 340 were on hemodyalysis, 541 (10.8%) had peripheral artery disease, 499 (10.0%) had prior stroke, and 384 (7.7%) had atrial fibrillation.

Participant flow

Between January 2010 and December 2016, 5007 patients who underwent FFR evaluation were screened, 2 did not meet the inclusion criteria, and 1 met the exclusion criteria. In the end, 50004 patients were enrolled and were followed until March 2020.

Adverse events

No adverse event related to this study was observed due to the nature of the retrospective study.

Outcome measures

During the follow up, 87 patients suffered from cardiac death and 59 patients suffered non-fatal myocardial infarction. The cumulative incidence of cardiac death was 0.44% at 1 year, 1.27% at 3 year, and 2.3% at 5 year. With regard to non-fatal myocardial infarction, the cumulative incidence was 0.27% at 1 year, 0.8% at 3 year, and 1.54% at 5 year.
