Abstract

Randomized clinical trials (RCT) have shown statin treatment to slow down the increase in carotid artery intima-media thickness (IMT) seen with ageing. However, those RCTs usually have a limited follow-up (1-3 years). Here an observational study was used to investigate the real-life effect of new statin treatment over a 10-year follow-up. In the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study, 954 individuals all aged 70 years at baseline were investigated regarding carotid artery IMT three times during 10 years (n = 771 at age 75, and n = 591 at age 80). At age 70, 503 subjects were statin-naïve and did not receive statin during the 10-year follow-up period (the never-statin group), while 197 subjects were statin-naïve but received statins during the follow-up period (the received-statin group). Low-density lipoprotein (LDL)-cholesterol increased over time in the never-statin group (+0.1 mmol/l, p = 0.0012), but decreased in the group receiving statin treatment (-1.1 mmol/l, p < 0.0001). The never-statin group increased significantly in IMT over the 10 years (+0.07 mm, p < 0.0001), while the numerical increase seen in the received-statin group was not significant (+0.02 mm, p = 0.22) A significant...Continue Reading

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
