Background Lipoprotein(a) [Lp(a)] is a risk factor for atherosclerosis and increases with age. The purpose of this study was to determine the effect of ageing on Lp(a) for three different apo(a) phenotypes. Methods We measured plasma Lp(a) concentrations in 551 unrelated Japanese subjects (20-88 years of age). We performed statistical analyses separately for three apo(a) phenotypes: the low-molecular-weight (LMW) phenotype with the F, B or S1 isoform, the intermediate-molecular-weight (IMW) phenotype with the S2 isoform and the high-molecular-weight (HMW) phenotype with the S3 or S4 isoform. Results For each phenotype, the mean plasma Lp(a) concentration and the frequency of Lp(a) concentrations ≥ 250 mg/L increased with age. Further, a statistically significant difference was always found between the younger subjects (20-39 years of age) and the elderly (over 60 years). The frequency of coronary heart disease increased with age, particularly for the LMW and IMW phenotypes. Conclusions We conclude that ageing elevates plasma Lp(a) concentrations, which may have a role in the prevalence of coronary heart disease in the elderly, especially those with the LMW or IMW phenotypes.

Background Dietary habits are associated with obesity which is a risk factor for coronary heart disease. The objective is to estimate the change of lipoprotein(a) and other lipoprotein classes by calorie restriction with obesity index and Framingham risk score. Methods Sixty females (56 ± 9 years) were recruited. Their caloric intakes were reduced during the six-month period, and the calorie from fat was not more than 30%. Lipoprotein profiles were estimated at baseline and after the six-month period of calorie restriction. Cholesterol levels in six lipoprotein classes (HDL, LDL, IDL, VLDL, chylomicron and lipoprotein(a)) were analysed by anion-exchange liquid chromatography. The other tests were analysed by general methods. Additionally, Framingham risk score for predicting 10-year coronary heart disease risk was calculated. Results Body mass index, waist circumference, insulin resistance, Framingham risk score, total cholesterol, LDL-cholesterol and IDL-cholesterol were significantly decreased by the calorie restriction, and the protein and cholesterol levels of lipoprotein(a) were significantly increased. The change of body mass index was significantly correlated with those of TC, VLDL-cholesterol and chylomicron-cholesterol, and that of waist circumference was significantly correlated with that of chylomicron-cholesterol. The change of Framingham risk score was significantly correlated with the change of IDL-C. Conclusion Obesity indexes and Framingham risk score were reduced by the dietary modification. Lipoprotein profile was improved with the reduction of obesity indexes, but lipoprotein(a) was increased. The changes of obesity indexes and Framingham risk score were related with those of triglyceride-rich lipoproteins, e.g. IDL, VLDL and CM.

Introduction: There is no common opinion about threshold lipoprotein(a) [Lp(a)] concentration for atherosclerotic cardiovascular diseases (ASCVD) risk. Different clinical guidelines and consensus documents postulated cut-off Lp(a) level as 30 mg/dL or 50 mg/dL. We assessed the concentration of Lp(a) that associated with ASCVD of different locations. Methods: The study included 1224 patients with ASCVD. Lp(a) concentration was measured by enzyme-linked immunosorbent assay in serum. Patients were divided into 3 groups: group I - Lp(a)<30 mg/dL, group II - 30≤Lp(a)<50 mg/dL, group III - Lp(a)≥50 mg/dL (table). Results: Coronary heart disease, carotid artery disease, lower extremity artery disease, myocardial infarction and ischemic stroke were diagnosed in 61%; 34%; 23%; 42% and 11% patients, respectively. Lower extremity artery disease, carotid artery disease and myocardial infarction were more frequent in patients with Lp(a) concentration from 30 to 50 mg/dL compared to patients with Lp(a) <30 mg/dL: 36%, 41%, 48% vs. 17%, 30%, 36% respectively, p<0.01 for all. Subjects with Lp(a) 30-50 mg/dL (n=182, 15%) had a greater odds ratio of lower extremity artery disease, carotid artery disease and myocardial infarction compared to patients with Lp(a) <30 mg/dL (table). ROC analysis demonstrated that Lp(a) cut-off levels for lower extremity artery disease, carotid artery disease, coronary heart disease and myocardial infarction were 26; 21; 37 and 36 mg/dL, respectively. Conclusions: Our results demonstrate that in case of Lp(a) cut-off level of 50 mg/dL about 15% of patients are underestimated for the risk of ASCVD. Lp(a) cut-off level for ASCVD is between 20 and 40 mg/dL regarding the atherosclerosis location.
