Comparison of the frequency and level of serum total cholesterol >300 mg/dL in patients at the same Texas hospital in a single month in 1993 and in 2013

摘要

The clinical pathology laboratory database of a large tertiary hospital in Dallas, Texas, was searched for patients having a serum total cholesterol > 300 mg in a single month in 1993 and in 2013. In September 1993, 63 patients had a serum total cholesterol > 300 mg/dL (range 302–1515 [mean 431, median 349]), and in September 2013, 12 patients had serum total cholesterol levels > 300 mg/dL (range 303–442 [mean 334, median 316.5]), an 81% decline in the numbers of patients and a 23% decline in the average total cholesterol levels during the 20-year period.
