Abstract
Objective: A growing number of studies have suggested a crucial role for a variety of inflammatory mediators in myocardial infarction. Recently, several flavonoids have been shown to have cardioprotective and anti-inflammatory properties. Therefore, the aim of this study was to investigate the effect of hesperidin—a common constituent of citrus fruits—on the serum levels of inflammatory markers and adipocytocines in patients with myocardial infarction.
Methods: Seventy-five patients with myocardial infarction were participated in this randomized, double-blind controlled clinical trial and were assigned to 2 intervention and control groups. Subjects consumed 600 mg/d pure hesperidin supplement and placebo in the intervention and control groups, respectively, for 4 weeks. Serum concentrations of inflammatory markers and adipocytocines were measured at baseline and at the end of the intervention.
Results: Consumption of 600 mg/day hesperidin significantly decreased the serum levels of E-selectin and increased adiponectin and high-density lipoprotein cholesterol (HDL-C) concentrations in patients with myocardial infarction. The improvement in other inflammatory markers, such as interleukin (IL)-6, high-sensitivity C-reactive protein (hs-CRP), leptin, and other lipid profile was also observed at the end of the intervention, compared to the baseline values, but the difference between the hesperidin and placebo groups was not statistically significant (p > 0.05).
Conclusion: Hesperidin supplementation could compensate for decreased levels of adiponectin and HDL-C and increased levels of E-selectin in patients with myocardial infarction. These results support the concept that certain flavonoids in the diet can be associated with significant health benefits, including heart health.
