baseline creatine kinase levels)

•Idiopathic hyperCKemia‡

•Seizure or severe chills

† For patients who present with cramping

in their calves or thighs.

‡ Refers to elevated creatine kinase level

without another cause identified

• Routine monitoring of liver enzymes in the blood

is no longer needed

FDA Advisory : Statins Feb 28, 2012

• People being treated with statins may have an

increased risk of raised blood sugar levels and

the development of Type 2 diabetes

• Some medications interact with lovastatin and

can increase the risk of muscle damage.

• Cognitive impairment ( memory loss,

forgetfulness and confusion) has been

reported by some statin users

Take Home Messages:

• Integrating lifestyle and diet changes with

medical Rx key to lipid management

• Dietary changes and exercise are best initial

steps to treating hypertriglyceridemia

• Statins and fish oil are the only medical Rx

shown to consistently lower CV mortality

• For primary prevention, elderly patients derive

most benefit from statin therapy.

• Statin intolerance is more common than

previously thought and must be addressed
