CRP and metabolic syndrome: These patients had higher CRP values (median = 121, IQR = 4–150 vs. median = 105, IQR = 2–132.5, p = 0.012), lower values of HDL-cholesterol (median = 40, IQR = 40–42 vs. median = 42, IQR = 40–44, p = 0.018), higher frequencies of triglycerides dyslipidemia (55.2% vs. 40.7%, p = 0.047), and lower frequencies of secondary ST-T changes (38.1% vs. 23%, p = 0.031) than patients without mitral regurgitation.
