HDL and Apo-A1 levels analysis. a Graphic representation of HDL levels in HC, mild MR, moderate MR and severe MR. HDL levels were decreased in severe MR compared to HC (p = 0.02) and compared to mild MR (p = 0.007). HDL levels were also reduced in moderate MR compared to mild MR (p = 0.04). b Graphic representation of Apo-A1 levels in HC and the 3 MR groups. Apo-A1 levels were significantly reduced in severe MR compared to moderate MR (p = 0.04), mild MR (p = 0.001) and HC (p = 0.009). HDL and Apo-A1 levels were measured using enzymatic colorimetric test and nephelometry respectively on all individual samples
