Background Although trials suggest that anti‐inflammatory approaches targeting interleukin (IL)‐6 signaling can reduce cardiovascular risk, it remains unknown whether targeting IL‐6 signaling could reduce risk additively to low‐density lipoprotein cholesterol (LDL‐C) lowering. Here, we assess interactions in associations of genetic downregulation of IL‐6 signaling and LDL‐C lowering with lifetime cardiovascular disease risk. Methods and Results Genetic scores for IL‐6 signaling downregulation and LDL‐C lowering were used to divide 408 225 White British individuals in UK Biobank into groups of lifelong exposure to downregulated IL‐6 signaling, lower LDL‐C, or both. Associations with risk of cardiovascular disease (coronary artery disease, ischemic stroke, peripheral artery disease, aortic aneurysm, vascular death) were explored in factorial Mendelian randomization. Compared with individuals with genetic IL‐6 and LDL‐C scores above the median, individuals with LDL‐C scores lower than the median but IL‐6 scores above the median had an odds ratio (OR) of 0.96 (95% CI, 0.93–0.98) for cardiovascular disease. A similar OR (0.96; 95% CI, 0.93–0.98) was estimated for individuals with genetic IL‐6 scores below the median but LDL‐C scores above the median. Individuals with both genetic scores lower than the median were at lower odds of cardiovascular disease (OR, 0.92; 95% CI, 0.90–0.95). There was no interaction between the 2 scores (relative excess risk attributed to interaction index, 0; synergy index, 1; P for multiplicative interaction=0.51). Genetic IL‐6 score below the median was associated with lower cardiovascular disease risk across measured LDL‐C strata (<100 or ≥100 mg/dL). Conclusions Genetically downregulated IL‐6 signaling and genetically lowered LDL‐C are associated with additively lower lifetime risk of cardiovascular disease. Future trials should explore combined IL‐6 inhibition and LDL‐C lowering treatments for cardiovascular prevention.

Aims Averaged measurements, but not the progression based on multiple assessments of carotid intima-media thickness, (cIMT) are predictive of cardiovascular disease (CVD) events in individuals. Whether this is true for conventional risk factors is unclear. Methods and results An individual participant meta-analysis was used to associate the annualised progression of systolic blood pressure, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol with future cardiovascular disease risk in 13 prospective cohort studies of the PROG-IMT collaboration ( n = 34,072). Follow-up data included information on a combined cardiovascular disease endpoint of myocardial infarction, stroke, or vascular death. In secondary analyses, annualised progression was replaced with average. Log hazard ratios per standard deviation difference were pooled across studies by a random effects meta-analysis. In primary analysis, the annualised progression of total cholesterol was marginally related to a higher cardiovascular disease risk (hazard ratio (HR) 1.04, 95% confidence interval (CI) 1.00 to 1.07). The annualised progression of systolic blood pressure, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol was not associated with future cardiovascular disease risk. In secondary analysis, average systolic blood pressure (HR 1.20 95% CI 1.11 to 1.29) and low-density lipoprotein cholesterol (HR 1.09, 95% CI 1.02 to 1.16) were related to a greater, while high-density lipoprotein cholesterol (HR 0.92, 95% CI 0.88 to 0.97) was related to a lower risk of future cardiovascular disease events. Conclusion Averaged measurements of systolic blood pressure, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol displayed significant linear relationships with the risk of future cardiovascular disease events. However, there was no clear association between the annualised progression of these conventional risk factors in individuals with the risk of future clinical endpoints.

There is a lack of research on the use of electronic tools that guide patients toward reducing their cardiovascular disease risk. We conducted a 9-month clinical trial in which participants who were at low (n = 100) and moderate (n = 23) cardiovascular disease risk—based on the National Cholesterol Education Program III’s 10-year risk estimator—were randomized to usual care or to usual care plus use of an Interactive Cholesterol Advisory Tool during the first 8 weeks of the study. In the moderate-risk category, an interaction between treatment condition and Framingham risk estimate on low-density lipoprotein and non-high-density lipoprotein cholesterol was observed, such that participants in the virtual clinician treatment condition had a larger reduction in low-density lipoprotein and non-high-density lipoprotein cholesterol as their Framingham risk estimate increased. Perceptions of the Interactive Cholesterol Advisory Tool were positive. Evidence-based information about cardiovascular disease risk and its management was accessible to participants without major technical challenges.
