ObjectivesRecent reports suggest a high prevalence of hypertension and diabetes in COVID-19 patients, but the role of cardiovascular disease (CVD) risk factors in the clinical course of COVID-19 is unknown. We evaluated the time-to-event relationship between hypertension, dyslipidaemia, diabetes and COVID-19 outcomes.DesignWe analysed data from the prospective Dutch CovidPredict cohort, an ongoing prospective study of patients admitted for COVID-19 infection.SettingPatients from eight participating hospitals, including two university hospitals from the CovidPredict cohort were included.ParticipantsAdmitted, adult patients with a positive COVID-19 PCR or high suspicion based on CT-imaging of the thorax. Patients were followed for major outcomes during the hospitalisation. CVD risk factors were established via home medication lists and divided in antihypertensives, lipid-lowering therapy and antidiabetics.Primary and secondary outcomes measuresThe primary outcome was mortality during the first 21 days following admission, secondary outcomes consisted of intensive care unit (ICU) admission and ICU mortality. Kaplan-Meier and Cox regression analyses were used to determine the association with CVD risk factors.ResultsWe included 1604 patients with a mean age of 66±15 of whom 60.5% were men. Antihypertensives, lipid-lowering therapy and antidiabetics were used by 45%, 34.7% and 22.1% of patients. After 21-days of follow-up; 19.2% of the patients had died or were discharged for palliative care. Cox regression analysis after adjustment for age and sex showed that the presence of ≥2 risk factors was associated with increased mortality risk (HR 1.52, 95% CI 1.15 to 2.02), but not with ICU admission. Moreover, the use of ≥2 antidiabetics and ≥2 antihypertensives was associated with mortality independent of age and sex with HRs of, respectively, 2.09 (95% CI 1.55 to 2.80) and 1.46 (95% CI 1.11 to 1.91).ConclusionsThe accumulation of hypertension, dyslipidaemia and diabetes leads to a stepwise increased risk for short-term mortality in hospitalised COVID-19 patients independent of age and sex. Further studies investigating how these risk factors disproportionately affect COVID-19 patients are warranted.

Patients were followed for major outcomes during hospitalization. CVD risk factors were established via home medication lists and divided in antihypertensives, lipid lowering therapy, and antidiabetics.Primary and secondary outcomes measuresThe primary outcome was mortality during the first 21 days following admission, secondary outcomes consisted of ICU-admission and ICU-mortality.

Further studies investigating how these risk factors disproportionately affect COVID-19 patients are warranted.Strengths and limitations of this studyWhile previous data reported a high prevalence of CVD risk factors in COVID-19 patients, this study investigated whether diabetes, dyslipidemia and hypertension predict adverse outcomes.This study is limited by the use of medication as surrogate for cardiovascular risk factorsThe causality of the investigated risk factors remains to be addressed in future studies.

Abstract Background Over time, guidelines for dyslipidemia management in patients at high risk of atherosclerotic cardiovascular disease (CVD) changed with the goal of improving patient outcomes. Guidelines have been released by the European Joint Task Force in 2007, 2012 and 2016, European Society of Cardiology in 2011, 2016 and 2019, Joint British Societies in 2014, and National Institute for Health and Care Excellence in 2014. Purpose Evaluate cardiovascular risk factors, treatment patterns, and cardiovascular outcomes over time related to dyslipidemia management. Methods Ten prevalent cohorts of patients with documented CVD receiving lipid-lowering therapy (LLT) were created using Clinical Research Practice Datalink (CPRD) records as of January 1, each year from 2008 through 2017. For each cohort, we identified CVD risk factors and LLT, and estimated the 1-year composite rate of fatal and nonfatal myocardial infarction (MI), ischemic stroke (IS), or revascularization. Patient follow-up was censored at the earliest of one year, end of data, or the outcome of interest. Patients in each cohort were required to be ≥18 years old, have ≥1 years of available medical history, and have received ≥2 LLT prescriptions in the prior year. Documented CVD was defined as MI, IS, angina, revascularization, transient ischemic attack, carotid stenosis, abdominal aortic aneurysm, or peripheral arterial disease. Patients could be in multiple cohorts. Results Annual patient counts ranged from 170,501 to 179,137 through 2013 and declined to 94,418 by 2017 (due to fewer patients in the overall CPRD data). Comparing 2008, 2011 (when ESC guidelines were revised) and 2017 showed the following for CVD risk factors: mean age was 71.6, 72.3, and 72.5 years; males were 59.9%, 61.1%, and 63.1%; current smoking was 15.1%, 15.2%, and 13.9%; type 2 diabetes was 18.4%, 20.2%, and 22.4%; stage 3–5 chronic kidney disease was 22.4%, 25.1%, and 22.8%; history of MI was 22.5%, 23.9%, and 27.4%; history of IS was 5.5%, 6.6%, and 7.9%; LDL <1.8 mmol/L was 27.8%, 29.2% and 37.2%; and LDL <1.4 mmol/L was 9.9%, 10.1%, and 15.6%. In terms of treatment, high intensity statin use increased from 12.9% to 15.7% to 30.8%; atorvastatin 40–80 mg use increased from 12.9% to 15.5% to 30.5%; while simvastatin 20–40 mg use decreased from 55.4% to 58.8% to 36.7%. The 1-year cardiovascular event rate declined from 2.54 to 2.35 to 1.96 events per 100 person-years (Figure). Conclusions After 2011 in the UK, there was an increased use of high intensity statins, a greater proportion of patients with LDL levels <1.8 and <1.4 mmol/L, and lower 1-year cardiovascular event rates. While improved CVD management likely contributed to the event rate decline, less than 40% of very high-risk patients achieved an LDL <1.8 mmol/L, and the proportion with LDL <1.4 mmol/L, as recommended by the 2019 ESC guidelines, was less than 20%. Clinicians should continue their efforts to reduce LDL in these patients. Figure 1 Funding Acknowledgement Type of funding source: Private company. Main funding source(s): Amgen

Abstract Introduction In the Netherlands, the total number of yearly measured lipid profiles exceeds 500,000. While lipid values are strongly affected by age and sex, until recently, no up-to-date age- and sex-specific lipid reference values were available. We describe the translation of big-cohort lipid data into accessible reference values, which can be easily incorporated in daily clinical practice. Methods Lipid values (total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides) from all healthy adults and children in the LifeLines cohort were used to generate age- and sex-specific percentiles. A combination of RStudio, Cascading Style Sheets and HyperText Markup Language was used to interactively display the percentiles in a responsive web layout. Results After exclusion of subjects reporting cardiovascular disease or lipid-lowering therapy at baseline, 141,611 subjects were included. On the website, input fields were created for age, sex and all main plasma lipids. Upon input of these values, corresponding percentiles are calculated, and output is displayed in a table and an interactive graph for each lipid. The website has been made available in both Dutch and English and can be accessed at www.lipidtools.com. Conclusion We constructed the first searchable, national lipid reference value tool with graphical display in the Netherlands to use in screening for dyslipidaemias and to reduce the underuse of lipid-lowering therapy in Dutch primary prevention. This study illustrates that data collected in big-cohort studies can be made easily accessible with modern digital techniques and preludes the digital health revolution yet to come.

Background South Asians have increased disk for cardiovascular disease (CVD) that is not captured by traditional risk factors, including TC and LDL-c. Low-density apolipoprotein-B (apoB) containing lipoproteins are heterogeneous in size and composition, and the particles with the greatest triglyceride content are thought to ultimately be the most atherogenic. Specific composition of low-density lipoproteins is not captured by common lipid measures (i.e. TC, LDL-c). A high proportion of triglyceride-rich low-density lipoproteins could be a mechanism for CVD risk in South Asians. Our objective was to compare mean TC, LDL-c, HDL-c, triglycerides, and apoB-triglyceride ratio (an estimate of low-density lipoprotein content) between South Asian-Americans and the US population. Methods We studied 2,876 South Asian adults living in the United States participating in a wellness program. Demographics were obtained by self-report. Lipoprotein levels were measured after 10-hour fast. US population means were calculated from NHANES (2007-2008, n = 5,113). Individuals on lipid-lowering therapy were excluded (780 (33%) South Asians, 1,194 (19%) NHANES). Results LDL-c (118mg/dL vs 116mg/dL, p<0.05) and triglycerides (139mg/dL vs 131 mg/dL, p<0.05) were higher in South Asians than the US population, whereas TC was lower (192mg/dL vs 197 mg/dL, p<0.05). HDL-c was lower in South Asians (46mg/dL vs 52mg/dL, p<0.05). ApoB was not statistically significantly different (93mg/dL vs 92mg/dL, p = 0.1), however the apoB/triglyceride ratio was lower in South Asians (0.8 vs 0.9, p<0.05). After stratifying for age by decade and gender, we found that South Asians have lower HDL-c until the age of 50, and lower apoB/triglyceride ratio until the age of 60, with no substantial differences between men and women. Conclusions Mean TC, LDL-c, and triglycerides were normal in South Asians, however the apoB/triglyceride ratio was lower in South Asians than in the US population. This finding indicates that a higher proportion of low-density lipoproteins in South Asians are of the triglyceride-rich atherogenic type. This may portend non-HDL-c as a better indicator of CVD risk than LDL-c in South Asians. Further, low apoB/triglyceride ratio and low HDL-c occurs at a young age in South Asians, suggesting that onset of risk is early. The disappearance of these patterns after age 60 may be the result of sample bias (excluding individuals on lipid lowering therapy), and/or survival bias.

Abstract Background Neuromedin U (NMU) is a hypothalamic neuropeptide with several functions, considered to be a potential therapeutic target for diabetes mellitus. The aim of this study was to analyse the association between genetic variants in NMU pathway genes and cardiovascular risk, in Italian adults from the general population recruited for the Moli-sani study. Methods A total of 4,039 participants (mean age 55.8±12.1 SD; men 46.1%) were randomly selected from the whole study population (N = 24,325; recruitment years 2005-2010). DNA from blood samples stored in the Moli-sani biobank were genotyped for 14 single nucleotide polymorphisms (SNPs) in the genes encoding for NMU, Neuromedin S (NMS) and their receptors NMUR1 and NMUR2. Cox regression analysis (age, sex, BMI, blood pressure, glucose and lipid levels as covariates) was performed to estimate the associations between SNPs and fatal or non-fatal CVD events (validated myocardial infarction or stroke), identified from death certificates and electronic records during a median follow-up of 4.5 years. A genetic score was then computed. Results CVD events (N = 93) were associated with mutant alleles in the NMU SNP rs55796004 (HR = 1.94; 95%CI:1.08-3.48) and rs4856020 (HR = 0.52; 95%CI: 0.29-0.94) and in the NMS SNP rs12474526 (HR = 0.48, 95%CI:0.28-0.81), independently from CVD risk factors. A SNP in NMUR1 showed a borderline association (rs6754952, HR = 0.74; 95%CI:0.54-1.00). The derived genetic score was associated with CVD incidence with a HR of 1.57 (95%CI:1.25-1.96, per 1 score SD). A HR of 7.33 (95%CI:1.68-32.01) was found comparing the last vs the 1st decile of the genetic score. Conclusions Italian adults carrying variants in NMU pathway genes are at increased CVD risk. Intermediate phenotypes, mediating this association independent of classical risk factors, are unknown and should be investigated. Once confirmed, these results could be useful to improve CVD risk assessment and to plan cost-effective interventions. Key messages Polymorphisms in NMU pathway genes are associated with CVD risk independently of classical CVD risk factors, suggesting a potential clinical utility in CVD prediction when added to CVD risk algorithms. The unknown phenotype mediating the association between NMU genes polymorphisms and CVD development could be the neglected CVD risk factor potentially explaining the unpredicted CVD fraction.

Background: Health insurance plays an important role in access to medical care and is the focus of extensive policy efforts. We examined the association of health insurance with cardiovascular disease (CVD) incidence. Methods and Results: The Multi-Ethnic Study of Atherosclerosis, sponsored by the National Heart, Lung and Blood Institute of the NIH, followed a US cohort, aged 45-84 without clinical CVD at baseline, for a median of 12.2 years; 788 events occurred among 6,674 individuals. Data were stratified by baseline health insurance status. Kaplan-Meier survival and Cox regression analyses were used to assess the association between health insurance and incident CVD (myocardial infarction, resuscitated cardiac arrest, stroke, CVD death, and angina), adjusting for biomedical CVD risk (traditional risk factors, including age and race/ethnicity, and markers of subclinical atherosclerosis) and socioeconomic status (SES). The majority of individuals had private insurance (51%). Uninsured individuals (9%) were more likely to have untreated hypertension and diabetes, less likely to be on lipid-lowering therapy, and more likely to receive care in an Emergency Department (p < 0.0001). Income, 10-year CVD risk, and 10-year event-free survival varied across insurance groups ( Table ). After adjustment for biomedical CVD risk, individuals with health insurance had a lower risk of incident CVD compared to the uninsured (HR 0.72, p=0.03). However, with additional adjustment for SES (income, education, and employment), insurance was no longer associated with incident CVD (HR 0.78, p=0.12). Among the insurance groups, those with private insurance had a lower risk of incident CVD after adjustment for both biomedical CVD risk and SES (HR 0.70, p=0.03). Medicare and Medicaid coverage were not associated with incident CVD. The military/VA group had a lower risk of incident CVD with adjustment for biomedical CVD risk (HR 0.57, p=0.02) that was no longer significant after adjustment for SES (HR 0.66, p=0.09). Conclusions: The association of health insurance with CVD incidence varied by insurance group, and private insurance was associated with a lower risk of incident CVD. Further exploration of the features of health insurance coverage that impact CVD incidence may facilitate improvements in the primary prevention of CVD.

Background: Cardiovascular disease (CVD) is increasing in HIV-infected patients. Glyc A is a novel nuclear magnetic resonance (NMR) spectroscopy signal in plasma arising from the glycosylation of circulating acute phase proteins. The acute phase proteins have been independently associated with CVD in HIV patients, but the association of Glyc A and CVD has not been studied. We aimed to quantify the risk of CVD associated with Glyc A at baseline in HIV-positive patients enrolled in the Strategies for Management of Anti-Retroviral Therapy (SMART) study. Methods: In a nested case-control study, Glyc A was measured using NMR at baseline in 246 HIV positive patients [median age, interquartile range (IQR): 49 (44,56) years, 81 % male], who experienced a CVD event (defined as coronary heart disease (CHD), myocardial infarction, coronary artery disease requiring revascularization, atherosclerotic non-CHD (stroke and peripheral arterial disease), congestive heart failure and CVD or unwitnessed death) over an average of 2.8 years of follow-up and 472 matched controls. Odds ratios (ORs) associated with baseline levels of Glyc A for CVD were estimated using conditional logistic regression unadjusted and after adjustment for BMI, race, HIV-RNA and antiretroviral therapy status, smoking, prior CVD, diabetes, total/high-density lipoprotein cholesterol ratio, use of blood pressure and lipid-lowering drugs, hepatitis co-infection, CD4+ and major baseline ECG abnormalities. Results: At baseline median Glyc A (IQR) was 383 (333, 442) μmol/L in patients who developed a CVD event and 368 (322, 419) μmol/L in controls (P < 0.001 for difference). The unadjusted OR for CVD (highest versus lowest quartile) was 2.18 (with 95% confidence interval (CI) 1.38-3.44, P < 0.001). After adjustment for baseline covariates and CVD risk factors, OR was 2.20 (95% CI, 1.29-3.76, P = 0.004). Conclusion: Higher levels of Glyc A are associated with increased risk of CVD in HIV patients after considering established CVD risk factors.

Introduction: Coronary artery calcification (CAC) is prevalent among patients with chronic kidney disease (CKD) and predicts the risk of cardiovascular disease (CVD). Risk factors for the progression of CAC in patients with CKD have not been well studied. Hypothesis: We assessed the hypothesis that several established and novel CVD risk factors are associated with progression of CAC among patients with CKD. Methods: In a random subsample of 1,123 participants from the Chronic Renal Insufficiency Cohort (CRIC) Study, CAC was measured at baseline and the follow-up visit using electron beam computed tomography (CT) or multidetector CT. CAC progression was defined as an increase of Agatston score ≥100 units during follow-up. Multiple logistic regression and mixed-effects regression models were used to assess risk factors for progression of CAC. Results: Over an average of 3-year follow-up, 332 (29.6%) participants developed CAC progression. After adjusting for age, sex, race, clinical site, total cholesterol, HDL-cholesterol, systolic blood pressure, antihypertensive treatment, diabetes, and current smoking in the multivariable models, history of CVD (odds ratio [OR] 1.53, 95% CI 1.09-2.15, p=0.02), lipid-lowering treatment (OR 1.81, 95% CI 1.28-2.55, p<0.001), higher serum phosphate (OR 1.37, 95% CI 1.17-1.61, p<0.001), hemoglobin A1c (OR 1.32, 95% CI 1.10-1.58, p=0.002), and cystatin C (OR 1.24, 95% CI 1.06-1.45, p=0.007), and lower estimated-glomerular filtration rate (eGFR) (OR 1.32, 95% CI 1.10-1.56, p=0.002) were associated with CAC progression. In addition, lower physical activity, lipid-lowering treatment, body-mass index, LDL-cholesterol, lower serum calcium, phosphate, total parathyroid hormone, fibrinogen, interleukin-6, tumor necrosis factor-α, fibroblast growth factor-23, lower eGFR, cystatin C, and 24-hour urine albumin were associated with square root transformed change in CAC score from baseline in multiple-adjusted models. These findings persisted after additional adjustment for baseline CAC score. Conclusions: In conclusion, these data suggest that reduced kidney function, calcium and phosphate metabolic disorders and inflammation, in addition to established CVD risk factors, might play a role in CAC progression among patients with CKD.
