Because Diabetes Mellitus is one of the major risk factors for CV disease and lots of related evidences have been published including CARDS study that showed definite benefit of statin treatment in DM patients and influenced ADA guideline. & NCEP ATP III update. However, there are large unmet medical needs for DM patients who don't reach their target LDL-C level defined NCEPT ATP III update because of physicians usually start with the lowest dose of statin and then titrate to the goal. Thus, we are curious about changing our prescription pattern into more tailored way; selecting starting dose based on the individual risk factors and concomitant status will impact the goal achieving rate for DM patients. Besides that, we are going to find out preliminary data about other markers change; small dense LDL and adiponectine;. Small dense LDL-C is more inflammatory and atherogenic LDL-C that may explain the impact of triglyceride. Adiponectin is another good marker related with obesity and metabolic syndrome.
