Sex Differences in Long-Term Outcomes in Patients With Deferred Revascularization Following Fractional Flow Reserve Assessment: International Collaboration Registry of Comprehensive Physiologic Evaluation.

ABSTRACT: Background Sex-specific differences may influence prognosis after deferred revascularization following fractional flow reserve (FFR) measurement. This study sought to investigate the sex differences in long-term prognosis of patients with deferred revascularization following FFR assessment. Methods and Results A total of 879 patients (879 vessels) with deferred revascularization with FFR >0.75 who underwent FFR and coronary flow reserve measurements were enrolled from 3 countries (Korea, Japan, and Spain). Long-term outcomes were assessed in 649 men and 230 women by the patient-oriented composite outcome (POCO, a composite of any death, any myocardial infarction, and any revascularization). We applied inverse-probability weighting based on propensity scores to account for differences at baseline between women and men (age, hyperlipidemia, diabetes mellitus, diameter stenosis, lesion length, multivessel disease, FFR, coronary flow reserve. The median follow-up duration was 1855 days (745-1855 days). Median FFR values were 0.88 (0.83-0.93) in men and 0.89 (0.85-0.94) in women, respectively. The occurrences of POCO were significantly high in men compared with that in women (10.5% versus 4.2%, P=0.007). Kaplan-Meier analysis revealed that women had a significantly lower risk of POCO (?2=7.2, P=0.007). Multivariate COX proportional hazards regression analysis revealed that age, male, diabetes mellitus, diameter stenosis, lesion length, and coronary flow reserve were independent predictors of POCO. After applying IPW, the hazard ratio of males for POCO was 2.07 (95% CI, 1.07-4.04, P=0.032). Conclusions This large multinational study reveals that long-term outcome differs between women and men in favor of women after FFR-guided revascularization deferral.

Project description:Data are limited regarding outcomes of deferred lesions in patients with angiographically insignificant stenosis but low fractional flow reserve (FFR). We investigated the natural history of angiographically insignificant stenosis with low FFR among patients who underwent routine 3-vessel FFR measurement. From December 2011 to March 2014, 1136 patients with 3298 vessels underwent routine 3-vessel FFR measurement (3V FFR-FRIENDS study, ClinicalTrials.gov identifier NCT01621438), and this study analyzed the 2-year clinical outcomes of 1024 patients with 2124 lesions with angiographically insignificant stenosis (percentage of diameter stenosis <50%), in which revascularization was deferred. All lesions were classified according to FFR values, using a cutoff of 0.80 (high FFR >0.80 versus low FFR ≤0.80). The primary end point was outcome of major adverse cardiovascular events (a composite of cardiac death, myocardial infarction, and ischemia-driven revascularization) at 2 years. Mean angiographic percentage of diameter stenosis and FFR of total lesions were 32.5±10.3% and 0.91±0.08%, respectively. Among the total lesions with angiographically insignificant stenosis, 8.7% showed low FFR (185 lesions). The incidence of lesions with low FFR was 2.5%, 3.8%, 9.0%, and 15.1% in categories of percentage of diameter stenosis <20%, 20% to 30%, 30% to 40%, and 40% to 50%, respectively. At 2-year follow-up, the low-FFR group showed a significantly higher risk of major adverse cardiovascular events compared with the high FFR group (3.3% versus 1.2%, hazard ratio: 3.371; 95% CI, 1.346-8.442; P=0.009). In multivariable analysis, low FFR was the most powerful independent predictor of future MACE in deferred lesions with angiographically insignificant stenosis (adjusted hazard ratio: 2.617; 95% CI, 1.026-6.679; P=0.044). In deferred angiographically insignificant stenosis, lesions with low FFR showed significantly higher event rates than those with high FFR. FFR was an independent predictor of future major adverse cardiovascular events in lesions with angiographically insignificant stenosis. URL: http://www.clinicaltrials.gov.
