When groups were compared it was observed that, in those patients with AMI and chronic severe or moderate periodontitis, 24.2% had HDL-C values lower than 40 mg/dl, 78.8% had LDL-C values higher than 100 mg/dl, 55.2% had triglycerides over 150 mg/dl, and US–CRP over 2 mg/L in 53.3%. This evidence concerns the gene CRP and periodontitis.
