Statins aren’t only given to reduce the LDL cholesterol which by itself may or may not be an important risk factor. Statins tend to reduce inflammation and also have an anticoagulant effect. If blood sugar isn’t well controlled, it can increase arterial inflammation. The immune system attacks an inflamed arterial plaque, it ruptures and a clot forms which can cause a heart attack or stroke.
Half of people who have heart attacks have “normal” LDL cholesterol. But few people who have heart attacks have ideal blood sugar fasting BG (4-4.7) and HbA1c (4.6-5.0%), a low hs-CRP (<0.5), low homocysteine, low triglycerides, high HDL, normal blood pressure, normal BMI, little abdominal fat and a low Apo B particle count. CVD risk is multifactorial.
You might want to investigate the other risk factors before deciding whether or not to take a statin.
What LDL cholesterol level do you have that is “normal”?
