Recent studies have shown that female patients have higher fractional flow reserve (FFR) values for a given severity of coronary stenosis. However, gender differences in the coronary revascularization rates following FFR assessment are unknown.
The nationwide inpatient sample (NIS) database was used to identify all patients who underwent FFR in the United States between January 2009 and December 2010. We used propensity score matching in order to compare revascularization rates amongst men and women undergoing FFR measurements.
Amongst 3695 patients who underwent FFR, 1235 matched pairs of men and women were identified. The overall revascularization rates were lower in women then men (43% vs. 57%, p < 0.01). Women were less likely then men to undergo percutaneous (40.1% vs. 52.8%, p < 0.01) or surgical revascularization following FFR (5.2% vs. 7.4%, p = 0.03).
In this large observation study, we found that coronary revascularization rates are significantly lower in women who undergo FFR. This data corroborates the earlier finding that women have higher FFR values for the same amount of stenosis compared to men.
