Abstract:
BACKGROUND:Since flow-mediated dilatation (FMD) is influenced by different factors, its clinical usefulness and validation is widely discussed. AIM:To assess the major factors that determine FMD values in a wide range of subjects with and without cardiovascular (CV) risk factors/diseases (CVRF/CVD). METHODS AND RESULTS:617 consecutive patients (mean age: 50.1 ± 14.9 years, males: 349/56.5%) hospitalised between 2005 and 2011 were enrolled into the study. Demographic data and CVRF/CVD with a significant impact on FMD values were analysed: hyperlipidaemia, active smoking, arterial hypertension, coronary artery disease, diabetes mellitus and heart valve disease. The population was divided depending on the number of coexisting CVRF/CVD (0-, 1-, 2-, 3-, 4-, 5-CVRF/CVD groups). The median FMD value in the entire group of patients was 10% (5-17). An analysis of the FMD percentage in particular groups showed significantly higher FMD values in patients without any CVRF/CVD (group 0), as well as in patients with one coexisting CVRF/CVD (group 1) compared to the other groups. The presence of two or more CVRF/CVD was not associated with a significantly higher FMD reduction. The analysis of patients with only one CVRF/CVD revealed the lowest FMD values in patients with coronary artery disease. CONCLUSIONS:FMD is related to the number of traditional CVRF/CVDs; however, coronary artery disease has the most significant influence on FMD decrease among analysed factors. The value of FMD assessment in high risk patients is limited.
