CONCLUSIONS q. Despite widely available treatments for dyslipidemia, patients with very high and high CV risk remain at suboptimal LDL CHOL levels. q. Increasing adherence to current guidelines , statin intensity and the use of combination therapies could improve lipid target achievement. q. Novel treatment modalities may improve lipid goal achievement in the future
