All-cause mortality and cholesterol in the elderly Low TC (<5.5 mmol/l / 213 mg/dl) is associated with increased mortality among 80+-year olds. There was no clear optimal level of cholesterol in 80+-year-old people. Some studies found the intermediate level of the cholesterol (around 6 mmol/l / 232 mg/dl) to be associated with the lowest mortality, but this was not consistent. Few data on TC and mortality are available on 80+-year olds. Petersen L K et al. Age Ageing 2010;39:674-680

Conditions and Populations at High Risk of Statin Intolerance Liver diseases ALT > 3x ULN occurs in < 0.5% for moderatedose statins and rosuvastatin at all doses, and about 1% for 80 mg of atorvastatin or simvastatin. However, this might be an overstatement because, in most studies, the incidence of ALT increase was similar in statin and placebo patients, and because almost 50% of dyslipidaemic patients requiring statin treatment might have had established NAFLD.

(including 31 patients with positive clinical personal history of premature CAD - 10 pts. in total), and 228 subjects with LDL-C: 250 329 mg/dl and positive clinical personal history of premature CAD (7 pts. in total in DLCN criteria). The estimated overall prevalence of probable/definite FH ( 7 pts.) was 1,27% or 1 in 79, suggesting 400,457 Polish adults with FH or at the high risk of FH diagnosis.
