Abstract
In over 300,000 Swedish males and females aged 20 to 79 years total cholesterol and triglycerides were measured consecutively between 1985 and 1989. In a subsample of about 35,000 individuals apolipoprotein (apo) B (indicating atherogenic) and apo A-I (anti-atherogenic) were also measured. In the age group 40-49 years, 24% of the males and 12% of the females had hypercholesterolemia (> or = 6.5 mmol/L) and 14% and 3%, respectively had hypertriglyceridemia (> or = 2.3 mmol/L). Combined hyperlipidemia occurred in this age group in 7% of the males and in 1% of the females and was more common in males. In the same age group, 21% of the males and 8% of the females had high atherogenic apo B values (> 1.5 g/L). Low apo A-I was found in the whole population (20-79 years) in 13% of the males and in 10% of the females and varied only little with age. In the AMORIS (Apolipoprotein related MOrtality RISk) study these individuals are followed prospectively. The relations between lipids and apo B and apo A-I levels and risk for fatal acute myocardial infarction (AMI) are analyzed to investigate which of these lipids/apolipoproteins best predict AMI either as single determinants or in combination. After a mean observation time of about 22 months there is a 3-6-fold increase in AMI in relation to increasing cholesterol levels in males of 40-59 years. The largest increase was seen in the 40-49-year age group. A similar relationship was also found for triglycerides and AMI.(ABSTRACT TRUNCATED AT 250 WORDS)
