LDL-cholesterol unrelated to mortality among the elderly

For decades, the mainstream view has been that an elevated level of total cholesterol is a primary cause of atherosclerosis and cardiovascular disease.  However, less clear is the relationship between total cholesterol and LDL-cholesterol among older individuals.  To address this relationship, researchers examined the relationship between LDL-cholesterol and all-cause mortality and cardiovascular disease mortality among 29 cohorts that involved 68,094 people at least 60 years of age.  An inverse association between all-cause mortality and LDL-C was seen in 16 cohorts representing 92% of the number of participants, where this association was recorded.  In two cohorts, cardiovascular disease mortality was highest in the lowest LDL-C quartile and with statistical significance; in seven cohorts, no association was found.  In conclusion, high LDL-C is inversely associated with mortality in most people over 60 years.
