- Elevated body weight in adolescence is associated with early cardiovascular disease, but whether this association is traceable to weight in early adulthood, weight in midlife or to weight gain is not known. The aim of this study is to assess the risk of midlife coronary atherosclerosis being associated with body weight at age 20, body weight in midlife and body weight change.We used data from 25,181 participants with no previous myocardial infarction or cardiac procedure in the Swedish CArdioPulmonary bioImage Study (SCAPIS, mean age 57 years, 51% women). Data on coronary atherosclerosis, self-reported body weight at age 20 and measured midlife weight were recorded together with potential confounders and mediators. Coronary atherosclerosis was assessed using coronary computed tomography angiography (CCTA) and expressed as segment involvement score (SIS).The probability of having coronary atherosclerosis was markedly higher with increasing weight at age 20 and with mid-life weight (p<0.001 for both sexes). However, weight increase from age 20 until mid-life was only modestly associated with coronary atherosclerosis. The association between weight gain and coronary atherosclerosis was mainly seen in men. However, no significant sex difference could be detected when adjusting for the 10-year delay in disease development in women.Similar in men and women, weight at age 20 and weight in midlife are strongly related to coronary atherosclerosis while weight increase from age 20 until midlife is only modestly related to coronary atherosclerosis.

- BACKGROUND AND AIMS: Elevated circulating levels of osteoprotegerin (OPG) are known to add to the prediction of cardiovascular mortality. Our objective was to clarify the long-term risk associated with serum OPG and the possible influence of diabetes and statins on OPG levels in patients with stable coronary artery disease (CAD).METHODS: We assessed the placebo-treated group (n = 1998) from the CLARICOR trial (NCT00121550), a cohort with stable CAD. At entry, 15% of the participants had diabetes and 41% received statins. Serum OPG levels were measured in blood drawn at randomization. Participants were followed through public registers for 10 years.RESULTS: OPG levels correlated positively with diabetes status, age, CRP and female sex, but negatively with the use of statins. CAD participants with diabetes had significantly elevated serum OPG levels compared to participants without diabetes, p < 0.0001. The participants without diabetes treated with statins presented with significantly lower serum OPG levels than the corresponding non-statin-users (p < 0.0001). However, statin use showed no association with OPG levels in the participants with diabetes. High OPG levels at entry showed long-term associations with all-cause mortality and cardiovascular events (hazard ratio associated with factor 10 OPG increase 15.9 (95% CI 11.0-22.9) and 6.38 (4.60-8.90), p = 0.0001, even after adjustment for standard predictors (3.16 (1.90-5.25) and 2.29 (1.53-3.44), p < 0.0001).CONCLUSIONS: Circulating OPG holds long-term independent predictive ability for all-cause mortality and cardiovascular events in CAD participants. OPG levels were associated with diabetes, age, and female sex and statin treatment was associated with lower OPG levels in the absence of diabetes.

- Background: The relationship between genetically -driven liver fat and coronary heart disease (CHD) remains unclear. ApoB-containing lipoproteins are known causal factors for CHD and may explain this relationship. Methods and Results: We conducted a genome-wide association study (GWAS) in the UK Biobank to identify genetic variants associated with liver fat. We then investigated the effects that these genetic variants had on both apoB-containing lipoproteins and CHD. Using Mendelian Randomization (MR) analyses, we examined if the relationship between genetically -driven liver fat and CHD could be attributed to its effect on apoB-containing lipoproteins. We found 25 independent liver -fat associated single -nucleotide polymorphisms (SNPs) with differing effects on lipoprotein metabolism. The SNPs were classified into three groups/clusters. The first cluster (N = 3 SNPs) displayed lipoprotein -raising effects. The second cluster (N = 12 SNPs) displayed neutral effects on lipoproteins and the third cluster (N = 10 SNPs) displayed lipoprotein -lowering effects. For every 1% higher liver fat, the first cluster showed an increased risk of CHD (OR = 1.157 [95% CI: 1.108-1.208]). The second cluster showed a non -significant effect on CHD (OR = 0.988 [95% CI: 0.965-1.012], whereas the third cluster showed a protective effect of increased liver fat on CHD (OR = 0.942 [95% CI: 0.897-0.989]). When adjusting for apoB, the risk for CHD became null. Conclusions: Here, we identify 25 liver -fat associated SNPs. We find that SNPs that increase, decrease or have neutral effects on apoB-containing lipoproteins show increased, decreased or neutral effects on CHD, respectively. Therefore, the relationship between genetically -driven liver fat and CHD is mediated by the causal effect of apoB.

- Background and aims: The European Atherosclerosis Society (EAS) Lipid Clinics Network promoted a survey in order to identify and understand how and when lipoprotein(a) [Lp(a)] is tested and clinically evaluated in lipid clinics throughout Europe, and the challenges that may prevent evaluation from being carried out. Methods: This survey was divided into three areas of inquiry: background and clinical setting information of clinicians, questions for doctors who claimed not to measure Lp(a), in order to understand what were the reasons for not ordering the test, and questions for doctors who measure Lp(a), to investigate the use of this value in the management of patients. Results: A total of 151 centres clinicians filled in the survey, out of 226 invited. The proportion of clinicians who declare to routinely measure Lp(a) in clinical practice was 75.5%. The most common reasons for not ordering the Lp(a) test were the lack of reimbursement or of treatment options, the non-availability of Lp(a) test, and the high cost of performing the laboratory test. The availability of therapies targeting this lipoprotein would result in a greater propensity of clinicians to start testing Lp(a). Among those who declared to routinely measure Lp(a), the Lp(a) measurement is mostly requested to further stratify patients’ cardiovascular risk, and half of them recognized 50 mg/dL (approx. 110 nmol/L) as the threshold for increased cardiovascular risk due. Conclusions: These results warrant for a great deal of effort from scientific societies to address the barriers that limit the routine use of the measurement of Lp(a) concentration and to recognise the importance of Lp(a) as a risk factor.
