OBJECTIVES/SPECIFIC AIMS: Clinical guidelines recommend using predicted atherosclerotic cardiovascular disease (ASCVD) risk to inform treatment decisions. The objective was to compare the contribution of changes in modifiable risk factors Versus aging to the development of high 10-year predicted ASCVD risk. METHODS/STUDY POPULATION: Prospective follow-up of the Jackson Heart Study, an exclusively African-American cohort, at visit 1 (2000–2004) and visit 3 (2009–2012). Analyses included 1115 African-American participants without a high 10-year predicted ASCVD risk (<7.5%), hypertension, diabetes, or ASCVD at visit 1. We used the Pooled Cohort equations to calculate the incidence of high (≥7.5%) 10-year predicted ASCVD risk at visit 3. We recalculated the percentage with a high 10-year predicted ASCVD risk at visit 3 assuming each risk factor [age, systolic blood pressure (SBP), antihypertensive medication use, diabetes, smoking, total and high-density lipoprotein cholesterol], one at a time, did not change from visit 1. RESULTS/ANTICIPATED RESULTS: The mean age at visit 1 was 45.2±9.5 years. Overall, 30.9% (95% CI 28.3%–33.4%) of participants developed high 10-year predicted ASCVD risk. Aging accounted for 59.7% (95% CI 54.2%–65.1%) of the development of high 10-year predicted ASCVD risk compared with 32.8% (95% CI 27.0%–38.2%) for increases in SBP or antihypertensive medication initiation and 12.8% (95% CI 9.6%–16.5%) for incident diabetes. Among participants <50 years, the contribution of increases in SBP or antihypertensive medication initiation was similar to aging. DISCUSSION/SIGNIFICANCE OF IMPACT: Increases in SBP and antihypertensive medication initiation are major contributors to the development of high 10-year predicted ASCVD risk in African Americans, particularly among younger adults.

Objective: Metabolic syndrome (MetS) increases atherosclerotic cardiovascular disease (ASCVD) risk. Low HDL cholesterol (HDL-C) is a diagnostic criterion of MetS and a major ASCVD risk factor. HDL particle concentration (HDL-P) associates with incident ASCVD independent of HDL-C, but its association with incident MetS has not been studied. We hypothesized that HDL-P would be inversely associated with incident metabolic syndrome independent of HDL-C and other recognized risk factors. Methods: HDL-P was measured by NMR and visceral fat by MRI in participants of the Dallas Heart Study, a probability-based population sample of adults age 30-65. Participants with prevalent MetS, DM, CVD, cirrhosis, cancer, HIV, or renal failure were excluded. Incident MetS as defined by NCEP ATPIII criteria was determined in all participants after median follow-up period of 9.4 years. Results: Among a cohort of 1120 participants without DM or MetS at baseline (57% women, 45% Black, mean age 43), 22.8% had incident MetS at follow-up. HDL-P and HDL-C were modestly correlated (r=0.54, p<0.0001). The lowest quartile of HDL-P was associated with younger age, men, Hispanic ethnicity, lower total, HDL, and LDL cholesterol levels and particle sizes, and less reported alcohol intake. Participants in the lowest sex and race stratified quartile of HDL-P had the highest incidence of MetS (Figure). In models adjusted for traditional risk factors, HDL-C, visceral fat, HOMA-IR, and hs-CRP, the lowest quartile of HDL-P was associated with 65% increased risk of incident MetS (Figure). Conclusion: HDL-P is independently associated with incident MetS after adjustment for HDL-C, adiposity, inflammation, and markers of insulin sensitivity. Further studies are warranted to validate these findings and elucidate the mechanisms underpinning this association.

Abstract Background Guidelines to standardize treatment and follow-up strategies in pneumomediastinum cases are lacking. The aim of the study was to evaluate the etiology in pneumomediastinum cases and the results of treatment and follow-up. Results Nineteen patients with pneumomediastinum who were followed up in our clinic between 2015 and 2020 comprised the study population. Among the patients, 16 (84.2%) were male, and the mean age was 31.15 years. The chief presenting complaints were chest pain and dyspnea. Pneumomediastinum was spontaneous in 15/19 patients (including spontaneous pneumomediastinum with an underlying pathology in 3/15), traumatic in 3/19, and iatrogenic in 1/19. Spontaneous pneumomediastinum without underlying pathology was seen in younger adults (mean age: 23 years). Surgical intervention in traumatic and iatrogenic pneumomediastinum cases was compared with spontaneous cases and no statistically significant difference was observed (p=0.178). The mean hospital stay of all patients was 3.15 days. Only one patient had a recurrence and died, which was later determined to be a secondary spontaneous pneumomediastinum case. Conclusion Pneumomediastinum often occurs with an underlying pathology in advancing age and as spontaneous in younger patients. Therefore, “secondary spontaneous pneumomediastinum” subclass should be evaluated in the classification to facilitate to create a standard guideline and prevent overdiagnosis and overtreatment.

Abstract Background/Introduction Limited real-world data are available on attainment of low-density lipoprotein cholesterol (LDL-C) treatment goals in patients with atherosclerotic cardiovascular disease (ASCVD) in Canada. Purpose A retrospective observational study was conducted to describe types of ASCVD events/procedures, time between events and use of lipid lowering treatment (LLT) in patients who did not achieve LDL-C goal. Methods Patients in Ontario ≥65 years with a primary ASCVD event/procedure between 1 Apr 2005 and 31 Mar 2016, treated with an LLT and with index and follow up LDL-C values were identified from claims data at the Institute for Clinical Evaluative Sciences data repository. Patients were assessed over a 1-year follow up period for LDL-C goal attainment (&lt;2.0 mmol/L or 50% reduction from index LDL-C) and analysed by LLT and by index event type. Results Overall, 28% of 143,302 patients ≥65 years on LLT failed to attain LDL-C goal at follow up (Figure). The proportion of patients failing to achieve LDL-C goal decreased from 35% to 22% over the 11-year study period. Mean time between index and follow up LDL-C (based on lowest score &gt;2 weeks and up to 1 year after index LDL-C) was 203±97 days. When analysed by low-, moderate- or high-intensity statin, 57%, 30%, and 22% of patients failed to achieve LDL-C goal at follow up, respectively. Conclusions In this study, more than 1 in 4 patients with ASCVD in Ontario failed to achieve guideline recommended LDL-C goal despite treatment. In particular, ∼1 in 3 patients with cerebral and peripheral arterial disease were not at goal. An opportunity exists to better manage these high risk ASCVD patients with further statin intensification and additional LLTs This study made use of de-identified data from the ICES Data Repository, which is managed by the Institute for Clinical Evaluative Sciences with support from its funders and partners: Canada's Strategy for Patient-Oriented Research (SPOR), the Ontario SPOR Support Unit, the Canadian Institutes of Health Research and the Government of Ontario.

Background : Medication adherence (ADH) is key to decreasing hypertension (HTN)-related morbidity and mortality in older African-American (AA) adults. However, older AA adults have poorer ADH to prescribed antihypertensive medications when compared to their younger and Caucasian-American counterparts. Patient beliefs and cultural concepts about their medications influence their medication ADH. An important cultural concept in this regards is spirituality, which is a significant resource in the AA community. Thus, the purpose of this qualitative study was to explore the role of spirituality in ADH to antihypertensive medications for older AA adults. Methods: Older AA adults who were members of a Program of All Inclusive Care for the Elderly (PACE) and who were (a) diagnosed with HTN; (b) prescribed at least one antihypertensive medication; (c) self-identified as African-American or Black; and (d) self-identified as spiritual completed one in-depth individual face-to-face in this qualitative descriptive study informed by grounded theory. Demographic data were also collected. Results : Twenty-one PACE members completed the study. All of the participants were female. The mean age of participants was 73 years with most completing high school (67%). The mean HTN diagnosis was16.7 years and mean number of prescriptions for antihypertensives was 3.3. Participants indicated that their spirituality was used in a collaborative process with formal health care to manage their ADH to antihypertensive medications. This process was identified as Partnering with God to Manage My Medications. Partnering with God to Manage My Medications indicated that the PACE members acknowledged personal responsibility for adhering to their antihypertensive medication regimen but used their spirituality as a resource for making decisions to remain adherent; coping with medication side effects; and increasing their self-efficacy to deal with barriers to ADH . Conclusions : Spirituality played a positive role in medication adherence for the PACE members. Incorporating individual beliefs, such as spirituality, into patient treatment for HTN may capitalize on their inner resources for medication ADH and demonstrates culturally appropriate care.

Background: While HIV infection is associated with increased risk of ASCVD (atherosclerotic cardiovascular disease), it is unknown whether guidelines can identify HIV-infected adults who may benefit from statins. The purpose of our study was to compare the 2013 ACC/AHA and 2004 ATP III recommendations in a HIV population, and to evaluate associations with carotid artery intima-media thickness (CIMT) and plaque. Methods: We used ultrasound to measure CIMT at baseline and 3 years later in 352 HIV-infected adults with no ASCVD and not on statins. Plaque was defined as IMT > 1.5 mm. We compared 2013 ACC/AHA and 2004 ATP III recommendations, and evaluated associations with CIMT and plaque. Results: At baseline, the median age was 43 (IQR 39-49), 85% were male, 74% were on antiretroviral medication, and 50% had plaque. At follow-up, the median IMT progression was 0.052 mm/yr, and 66% had plaque. The 2013 guideline was more likely to recommend statins compared with the 2004 guideline, both overall (26% vs. 14%, p<.001), in those with plaque (32% vs. 17%, p=.0002), and in those without plaque (16% vs. 7%, p=.025). In unadjusted linear regression, the 2004 and 2013 risk score were strongly associated with CIMT (0.01 mm per 10% increase in risk, p<.001) and with CIMT progression (0.01 mm/yr per 10% increase in risk, p<.001). In multivariate analysis, older age, higher LDL-C, pack-years of smoking, and history of opportunistic infection were associated with baseline plaque. Conclusions: While the 2013 ACC/AHA guideline recommended statins to a greater number of HIV-infected adults compared to the 2004 ATP III guideline, both failed to recommend therapy in the majority of HIV-affected adults with carotid plaque. Both the 2004 and 2013 guidelines predicted higher levels of baseline CIMT and faster progression. HIV-specific guidelines that include detection of subclinical atherosclerosis may help to identify HIV-infected adults who are at increased ASCVD risk and may benefit from statins.

Introduction: Elevated plasma low-density lipoprotein cholesterol (LDL-C), small-dense LDL-C (sdLDL-C), LDL-triglyceride (LDL-TG), triglycerides (TG), remnant-lipoprotein cholesterol (RLP-C), triglyceride-rich lipoprotein-C (TRL-C), very low-density lipoprotein cholesterol (VLDL-C), and lipoprotein(a) [Lp(a)] levels have been associated with increased atherosclerotic cardiovascular disease (ASCVD) risk. However, these parameters have not been included in risk factors for ASCVD in the pooled cohort equation (PCE). Hypothesis: We assessed the hypothesis that these atherogenic lipoprotein parameters add significant information for ASCVD risk prediction in the Framingham Offspring Study. Methods: We evaluated 3,147 subjects without ASCVD at baseline (mean age 58 years) from participants of Framingham Offspring Study cycle 6, 677 (21.5%) of whom developed inclusive ASCVD over 16 years. Biomarkers of risk were assessed in frozen plasma samples. Total cholesterol, TG, HDL-C, direct LDL-C, sdLDL-C, LDL-TG, Lp(a), RLP-C, and TRL-C were measured by standardized automated analysis. Calculated LDL-C, large buoyant low-density lipoprotein cholesterol (lbLDL-C), VLDL-C, and non-HDL-C values were calculated. Data were analyzed using Cox proportional regression analysis and net reclassification improvement (NRI) analysis to identify parameters significantly associated with the incidence of ASCVD after controlling for standard ASCVD risk factor and applying the PCE model. Results: All specialized lipoprotein parameters were significant ASCVD risk factors on univariate analysis, but only direct LDL-C, sdLDL-C, and Lp(a) were significant on multivariate analysis with standard risk factors in the model. Together these parameters significantly improved the model c statistic (0.716 vs 0.732, P < 0.05) and net risk reclassification (mean NRI 0.104, P < 0.01) for ASCVD risk. Using the ASCVD risk pooled cohort equation, sdLDL-C, TG, LDL-TG, LDL-C, RLP-C, and TRL-C individually added significant information, but no other parameter added significant information with sdLDL-C (hazard ratio 1.30 for 75th vs 25th percentile, P < 0.0001) in the model. Conclusions: In multivariate analysis, sdLDL-C, direct LDL-C, and Lp(a) contributed significantly to ASCVD risk, but only sdLDL-C added significant risk information to the PCE model, indicating that sdLDL-C may be the most atherogenic lipoprotein particle.

IntroductionType 2 diabetes mellitus (T2D) confers high atherosclerotic cardiovascular disease (ASCVD) risk. The metabolite trimethylamine N-oxide (TMAO) derived via gut flora has been linked to excess ASCVD.Research design and methodsWe analyzed data, biospecimens, and major adverse cardiovascular events (MACEs) from the prospective multicenter randomized Action to Control Cardiovascular Risk in Diabetes (ACCORD) trial to assess its value in 330 high-risk individuals with T2D without evident atherosclerotic disease at enrollment.ResultsIncident cardiovascular events occurred in 165 cases; 165 controls matched by age, sex, and treatment arm experienced no incident events during follow-up. Cases and controls (mean age 64.5 years) had similar mean glycated hemoglobin (HbA1c) (8.2%) and mean 10-year ASCVD risk (23.5%); groups also had similar use of statins and antihypertensive medications at baseline and follow-up. Baseline plasma TMAO levels did not differ between groups after adjusting for ASCVD risk score, HbA1c, and estimated glomerular filtration rate, nor did TMAO distinguish patients suffering incident MACE from those who remained event-free.ConclusionsTMAO’s prognostic value for incident ASCVD events may be blunted when applied to individuals with T2D with poor glycemic control and high baseline ASCVD risk. These results behoove further translational investigations of unique mechanisms of ASCVD risk in T2D.

n-3 PUFA may exert favourable effects on several processes that may inhibit the atherosclerotic process. However, the role of n-3 PUFA in lowering the risk of atherosclerotic CVD (ASCVD) has been fiercely debated. In the present paper, we summarise the main findings from previous follow-up studies of intake and studies using adipose tissue as an objective biomarker to investigate exposure to n-3 PUFA in relation to ASCVD risk and discuss some perspectives for further research. The majority of previous studies investigating intake of marine- and plant-based n-3 PUFA have focused on CHD while other ASCVD such as ischaemic stroke and peripheral artery disease have been less studied. However, recent data from Danish Diet, Cancer and Health cohort suggest that marine n-3 PUFA may be inversely associated with risk of myocardial infarction, ischaemic stroke and peripheral arterial disease caused by atherosclerosis. The effect of the plant-derived n-3 PUFA α-linolenic acid on ASCVD is less clear and several gaps in the literature remain to be explored.

The treatment of lipid disorders begins with lifestyle therapy to improve nutrition, physical activity, weight, and other factors that affect lipids. Secondary causes of lipid disorders should be addressed, and pharmacologic therapy initiated based on a patient’s risk for atherosclerotic cardiovascular disease (ASCVD). Patients at extreme ASCVD risk should be treated with high-intensity statin therapy to achieve a goal low-density lipoprotein cholesterol (LDL-C) of <55 mg/dL, and those at very high ASCVD risk should be treated to achieve LDL-C <70 mg/dL. Treatment for moderate and high ASCVD risk patients may begin with a moderate-intensity statin to achieve an LDL-C <100 mg/dL, while the LDL-C goal is <130 mg/dL for those at low risk. In all cases, treatment should be intensified, including the addition of other LDL-C-lowering agents (i.e., proprotein convertase subtilisin/kexin type 9 inhibitors, ezetimibe, colesevelam, or bempedoic acid) as needed to achieve treatment goals. When targeting triglyceride levels, the desirable goal is <150 mg/dL. Statin therapy should be combined with a fibrate, prescription-grade omega-3 fatty acid, and/or niacin to reduce triglycerides in all patients with triglycerides ≥500 mg/dL, and icosapent ethyl should be added to a statin in any patient with established ASCVD or diabetes with ≥2 ASCVD risk factors and triglycerides between 135 and 499 mg/dL to prevent ASCVD events. Management of additional risk factors such as elevated lipoprotein(a) and statin intolerance is also described.
