Type 2 diabetes mellitus, metabolic syndrome, and mixed dyslipidemia: how similar, how different, and how to treat?

Abstract

Individuals with mixed atherogenic dyslipidemia, type 2 diabetes mellitus (T2DM), and metabolic syndrome are at high risk of developing cardiovascular disease (CVD) and can often benefit greatly from preventive lifestyle and medical interventions. These conditions typically co-exist in an individual, and the lipid profiles associated with them have several features in common. The worldwide prevalence of T2DM, atherogenic dyslipidemia, and metabolic syndrome is increasing, particularly in southern Asia and the Middle East. Statins can lower low-density lipoprotein-cholesterol and reduce the risk of CVD in these high-risk individuals, but there is a residual risk of CVD associated with additional lipid abnormalities, such as high levels of triglycerides and low levels of high-density lipoprotein cholesterol. These abnormalities are commonly found in patients with T2DM and metabolic syndrome. Additional lipid-modifying therapies that target these abnormalities, such as fibrates and omega-3 polyunsaturated fatty acids, may be able to improve lipid profiles and further reduce the risk of CVD in these patients.
