Plasma fibrinogen levels and all-cause and cause-specific mortality in an Italian adult population: results from the Moli-sani study
Bleeding, Thrombosis, and Vascular Biology(2023)
摘要
Epidemiological data on the association between fibrinogen levels and mortality are scarse and controversial. Longitudinal analyses were performed, separately by sex, on 17,689 individuals from the Moli-sani study [53% women, ≥35 years, free from cardiovascular disease (CVD) or cancer at enrolment], to evaluate the association between plasma fibrinogen and all-cause and cause-specific mortality. Over a median follow-up of 11.2 years, 1,058 deaths (34.7% CVD, 36.3% cancer) were ascertained. Both in the lowest (1.12-2.64 g/L) and highest (≥3.62 g/L) fibrinogen quintiles, women had an increased all-cause mortality hazard, when compared with third quintile (2.97-3.23 g/L). Dose-response analyses showed a U-shaped relationship in women (P overall <0.0001; P non-linear association <0.0001), but a positive linear association for all-cause mortality in men (P overall 0.0038; P non-linear association 0.76). Similar trends for a U-shaped association were observed for CVD mortality, while no association was observed with cancer deaths. A U-shaped association of fibrinogen levels with other-cause mortality was also found in both sexes. This study shows that not only higher but also lower fibrinogen levels represent hazard for mortality when compared to normal levels; U-shaped curves being prevalently observed in women.
