FABP4 and peripheral arterial disease: In a recent study evaluating FABP-4 prognostic value in PAD, it was found that each one-unit increase in FABP-4 was significantly associated with MALEs (HR 1.18, 95% CI 1.03–1.27; p = 0.022) and worsening PAD (adjusted HR 1.17, 95% CI 1.12–1.28; p < 0.001) [38].
