Aims Of The StudyFamilial Mediterranean fever (FMF) is a hereditary, auto-inflammatory disease, characterised by recurrent, self-limiting attacks of fever with inflammation of the serosal membranes, joints, and skin. Chronic inflammation was previously associated with increased risk for ischaemic heart disease (IHD). However, the association between FMF and IHD remains unclear. The objective of this study is to determine whether this association exists.MethodsUtilising the database of the largest health-care provider in Israel, a cross-sectional study was performed. The incidence of IHD was compared between patients diagnosed with FMF and age and sex-matched controls. Chi-square and t-test were used for categorial and continuous variables, and cox logistics regression model was used for multivariate analysis. Survival analysis was made using Kaplan-Meier plots and log-rank test.ResultsThe study included 7670 patients diagnosed with FMF and an equal number of controls without FMF. In a univariate analysis FMF was found to be associated with higher prevalence of IHD (OR 1.33) and increased mortality (OR 1.29). In a multivariate analysis FMF was found to be independently associated with increased risk for IHD (OR 1.44).ConclusionThe study shows that FMF is associated with both increased risk for IHD and higher mortality rates. An early diagnosis and treatment of this disease can potentially improve patients' life expectancy and decrease cardiac comorbidities.© 2020 John Wiley & Sons Ltd.
