We studied lipids, apolipoprotein-E (apo-epsilon) genotypes and other coronary artery disease (CAD) risk factors of 67 CAD patients (male/female ratio 5) in Curacao. Compared with 57 controls, male CAD patients had higher cholesterol, triglycerides, LDL-cholesterol, apo-B and decreased HDL-cholesterol and HDL-cholesterol/cholesterol concentrations. Other CAD risk factors were: increased fasting glucose and HbA(lc) concentrations, decreased creatinine clearance, and increased prevalences of lipoprotein (a) concentration >500 mg/l, renal disease, hyperhomocysteinaemia, diabetes mellitus type II (DM-II), positive CAD family history and cigarette smoking. Male CAD patients had higher plasma alpha-tocopherol(eq). Compared with 29 female controls, female CAD patients had higher fasting plasma glucose and HbA(lc) concentrations, and prevalence of DM-II; Predicting factors for CAD development in the whole CAD group were: DM-II, cigarette smoking, apo-epsilon(3)/epsilon(4) and apo-epsilon(4)/epsilon(4). Apo-epsilon(4) was associated with lower HDL- and higher LDL-cholesterol concentrations. There is a need for local studies on improvement of diabetic control, reference values of lipoprotein (a) and homocysteine concentrations, on apolipoprotein (a) phenotypes, causes of hyperhomocysteinaemia, and dietary influences on CAD development in subjects who carry the apo-epsilon(4) allele.

Patients with coronary artery disease are advised to augment their dietary linoleic acid intakes at the expense of saturated fatty acids. We investigated whether the dietary linoleic acid intake of 57 patients with coronary artery disease (47 males, 10 females; ages 61 +/- 10 years) in Curacao is higher as compared with 77 controls (51 males, 26 females; ages 56 +/- 7 years). For this, we measured plasma cholesterol ester fatty acids, which reflect the dietary fatty acid composition of the preceding weeks. Patients with coronary artery disease and controls had minor differences in cholesterol ester fatty acids. Their cholesterol ester linoleic acid content suggests that the dietary polyunsaturated/saturated fatty acid ratio is far below 1. Comparison with data reported for The Netherlands, Greenland and Crete showed that the dietary fatty acid composition in Curacao is typically Western with a high intake of saturated fatty acids, a low intake of monounsaturated fatty acids and the consumption of linoleic acid as the predominant polyunsaturated fatty acid. Intake of long chain polyunsaturated fatty acids from fatty fish is low. Reduction of dietary saturated fatty acids, augmentation of fish consumption, and an increase of the alpha-linolenic/linoleic acid ratio are likely to be of benefit to both primary and secondary prevention from coronary artery disease in Curacao.
