Relation of serum total cholesterol and high-density lipoprotein cholesterol percentage to the incidence of definite coronary events: twenty-year follow-up of the Donolo-Tel Aviv Prospective Coronary Artery Disease Study.

This 20-year follow-up report presents the incidence of definite coronary events and its relation to serum total cholesterol (TC) and alpha-lipoprotein cholesterol percentage (percentage of serum TC bound with alpha-lipoprotein), now usually called high-density lipoprotein cholesterol percentage (HDL-C%). The cohort consists of 1,454 men and 1,481 women, presumably healthy, aged 35 to 64 years at the time of entrance examination in 1964. During the follow-up period 123 men and 44 women died from coronary disease. Ninety-six men and 42 women had nonfatal myocardial infarctions. The incidence of definite coronary events increased from 6% in men with TC levels of less than 200 mg/dl to 25% in men with levels of more than 264 mg/dl. The corresponding figures in women were 3% and 10%. The incidence of definite coronary events was inversely correlated to HDL-C%. The incidence of definite coronary events in 225 men with HDL-C% of less than 14% was 28%, and in 669 men with HDL-C% of 21% or more, 7%. The corresponding figures in 234 women with HDL-C% of less than 17% was 14%, and in 853 women with HDL-C% of 23% or more, 2%. Two HDL-C% subsets were assessed: "low" and "high" subsets refer to HDL-C% of less than 21% and 21% or more, respectively, in men and less than 23% and 23% or more in women.(ABSTRACT TRUNCATED AT 250 WORDS)
