The INTERHEART study found that the ApoB100 / ApoA1 ratio is more effective at predicting heart attack risk, in patients who had had an acute myocardial infarction, than either the ApoB100 or ApoA1 measure alone. (ApoA1 is the major HDL protein.) In the general population this remains unclear although in a recent study ApoB was the strongest risk marker for cardiovascular events. A small study suggests that added to fluvastatin treatment, omega 3 fatty acids daily, containing 460 mg of E-EPA and 380 mg of E-DHA (ethyl esters), may lower ApoB48 in hyperlipemic type 2 diabetics.
