Trends and site-level variation of novel cardiovascular medication utilization among patients admitted for heart failure or coronary artery disease in the US Veterans Affairs System: 2017-2021.

BACKGROUND: We assessed trends in novel cardiovascular medication utilization in US Veterans Affairs (VA) for angiotensin receptor-neprilysin inhibitors (ARNI), sodium-glucose cotransporter-2 Inhibitors (SGLT2i), and glucagon-like peptide-1 receptor agonists (GLP-1 RA). METHODS: We retrospectively identified cohorts from 114 VA hospitals with admission for prevalent 1) systolic heart failure (HF, N = 82,375) or 2) coronary artery disease and diabetes (CAD+T2D, N = 74,209). Site-level data for prevalent filled prescriptions were assessed at hospital admission, discharge, or within 6 months of discharge. Variability among sites was estimated with median odds ratios (mOR), and within-site Pearson correlations of utilization of each medication class were calculated. Site- and patient-level characteristics were compared by high-, mixed-, and low-utilizing sites. RESULTS: ARNI and SGTL2i use for HF increased from <5% to 20% and 21%, respectively, while SGTL2i or GLP-1 RA use for CAD+T2D increased from <5% to 30% from 2017 to 2021. Adjusted mOR and 95% confidence intervals for ARNI, SGTL2i for HF, and SGTL2i or GLP-1 RA for CAD+T2D were 1.73 (1.64-1.91), 1.72 (1.59-1.81), and 1.53 (1.45-1.62), respectively. Utilization of each medication class correlated poorly with use of other novel classes (Pearson <0.38 for all). Higher patient volume, number of beds, and hospital complexity correlated with high-utilizing sites. CONCLUSIONS: Utilization of novel medications has increased over time but remains suboptimal for US Veterans with HF and CAD+T2D, with substantial site-level heterogeneity despite a universal medication formulary and low out-of-pocket costs for patients. Future work should include further characterization of hospital- and clinician-level practice patterns to serve as targets to increase implementation.

Assessment of Medication Adherence Using Pharmacy Data Before and After Percutaneous Coronary Intervention.

Objective: Adherence to anti-platelet medications is critical following coronary stenting, but prior studies indicate that clinician assessment and patient self-assessment of adherence are poorly correlated with future medication-taking behavior. We therefore sought to determine if integrated pharmacy data can be used to identify patients at high risk of non-adherence after percutaneous coronary interventions (PCI). Methods: Using Veteran Affairs (VA) Clinical Assessment, Reporting, and Tracking (CART) data linked with pharmacy records, we assessed adherence to cardiovascular medications from 2012 to 2018. Adherence was defined as the proportion of days covered (PDC) ≥ 0.80. We assessed the association of pre-PCI adherence with post-PCI adherence to P2Y12 inhibitors and clinical outcomes using logistic regression and Cox proportional hazard models, respectively. Results: Among 56,357 patients, 66.0% filled at least 1 cardiovascular medication within VA for the year prior to PCI and were evaluable for adherence. Pre-PCI non-adherence was 20.7%, and non-adherent patients were more likely to be younger and present non-electively. Non-adherent patients were less likely to adhere to P2Y12 inhibitor therapy after PCI (Adjusted OR 0.45 C.I. 0.41-0.46), compared with adherent patients, and had a higher adjusted risk of mortality (HR 1.17 C.I. 1.03-1.33). Conclusion: Adherence to cardiovascular medications prior to PCI can be assessed for most patients using pharmacy data, and past adherence is associated with future adherence and mortality after PCI. Use of integrated pharmacy data to identify high-risk patients could improve outcomes and cost-effectiveness of adherence interventions.

Anterior, posterior, or all-vessel infrapopliteal revascularization in patients with moderate-severe claudication: Insights from the LIBERTY 360 study.

BACKGROUND: Little data guides revascularization of infrapopliteal peripheral arterial disease (PAD) in patients with claudication. We assessed outcomes after infrapopliteal-only intervention for claudication in the LIBERTY 360 observational study. METHODS: In this post hoc analysis, LIBERTY 360 patients (N = 128) with claudication and isolated infrapopliteal disease undergoing endovascular revascularization were divided by territory into anterior-vessel, posterior-vessel, or all-vessel groups. Patients were followed for periprocedural, in-hospital, and long-term outcomes. Logistic regression for odds ratios, Cox proportional hazard models, ANOVA, and Kaplan-Meier estimates were utilized to compare outcomes. RESULTS: Patients underwent anterior (N = 37), posterior (N = 76), or all-vessel (N = 15) infrapopliteal revascularization. Initial procedural success was 86%, 86%, and 69% for anterior, posterior, and all-vessel groups, respectively. Each group had improvements in Rutherford classification (RC) from baseline to 2 years (mean RC change: -1.3, -1.5, and -1.5, respectively). Compared with all-vessel intervention, both anterior and posterior groups had lower rate of major adverse events (MAE) and target vessel revascularization (TVR) at 3 years (MAE: 12% and 15% in anterior and posterior groups, respectively compared with 51% in the all-vessel group; hazard ratios and 95% CIs 0.22 [0.06-0.74], p = .015; 0.24 [0.09-0.64], p = .004). Other outcomes were similar among the three groups. The anterior group showed more improvement in pain subdomain and total VascuQoL scores compared with posterior and all-vessel groups at 2 years (p = .016, p = .020 and p = .068, p = .009, respectively). CONCLUSIONS: Both anterior or posterior revascularization have favorable outcomes and may be beneficial for improvement of symptoms in claudicants with isolated infrapopliteal PAD.

Potential unrealized mortality benefit of glucagon-like peptide-1 receptor agonists and sodium-glucose co-transport-2 inhibitors: A report from the Veterans Health Administration Clinical Assessment, Reporting and Tracking program.

AIM: To assess the unrealized potential of glucagon-like peptide-1 receptor agonist (GLP-1RA) or sodium-glucose co-transport-2 inhibitor (SGLT2i) use to reduce mortality in veterans with type 2 diabetes (T2D), coronary artery disease (CAD), and other characteristics congruent with clinical trial cohorts that established the efficacy of these agents. METHODS: Veterans with T2D and CAD on angiography in 2014 who were untreated with either a GLP-1RA or a SGLT2i were assessed for key eligibility criteria of the LEADER (GLP-1RA) and EMPA-REG OUTCOME (SGLT2i) trials. Trial hazard ratios and 95% confidence intervals for all-cause death were applied to deaths observed in veterans through 2018 to estimate the potential benefit of GLP-1RA or SGLT2i use. RESULTS: Median observation was 4.3 years. Of 15 987 veterans with T2D and CAD, 1186 (7.4%) were excluded for GLP-1RA or SGLT2i treatment, and 1386 lacked glycated haemoglobin measurement. Of the remaining 13 415 patients, 4103 (30.1%) and 5313 (39.6%) fulfilled the key criteria for the LEADER and EMPA-REG OUTCOME trials, respectively. Death occurred in 1009 (24.6%) of LEADER-eligible patients and 1335 (25.1%) of EMPA-REG OUTCOME-eligible patients. Under treatment with liraglutide in LEADER-eligible veterans, a 3.5% (0.7%-6.2%) potential absolute mortality reduction, corresponding to 144 (28-253) fewer deaths (0.88 [0.17-1.56] per 100 person-years), might have been expected. Similarly, under treatment with empagliflozin in EMPA-REG OUTCOME-eligible veterans, a 7.9% (4.5%-10.8%) potential absolute mortality reduction, corresponding to 418 (230-573) fewer deaths (1.98 [1.14-2.72] per 100 person-years), might have been expected. CONCLUSIONS: This analysis indicates unrealized opportunities to reduce mortality in selected veterans with T2D and CAD via increased GLP-1RA and SGLT2i use.

Intervention for Iliofemoral Deep Vein Thrombosis and May-Thurner Syndrome.

May-Thurner syndrome, also known as iliac vein compression syndrome, may cause symptoms of venous hypertension and is a predisposing factor for the development of iliofemoral deep vein thrombosis (DVT). Iliofemoral DVT is associated with high rates of development of postthrombotic syndrome, a potentially debilitating condition associated with development of symptoms related to venous outflow obstruction and resulting in reduced quality of life. In this Clinics article, we review procedural intervention with catheter-directed thrombolysis and stenting for iliofemoral DVT and iliac vein compression.

Association of high-density lipoprotein particle concentration with cardiovascular risk following acute coronary syndrome: A case-cohort analysis of the dal-Outcomes trial.

BACKGROUND: High-density lipoprotein cholesterol (HDL-C) concentration is inversely related to risk of major adverse cardiovascular events (MACE) in epidemiologic studies but is a poorer predictor of MACE in patients with established coronary heart disease. HDL particle concentration (HDLP) has been proposed as a better predictor of risk. We investigated whether HDLP is associated with risk of MACE after acute coronary syndrome (ACS). METHODS: The dal-Outcomes trial compared the CETP inhibitor dalcetrapib with placebo in patients with recent ACS. In a nested case-cohort analysis, total, large, medium, and small HDLPs were measured by nuclear magnetic resonance spectroscopy at baseline (4-12 weeks after ACS) in 476 cases with MACE and 902 controls. Hazard ratios (HRs; case-control) for 1-SD increment of HDLP or HDL-C at baseline were calculated with and without adjustment for demographic, clinical, laboratory, and treatment variables. Similarly, HRs for MACE were calculated for changes in HDLP or HDL-C from baseline to month 3 of assigned treatment. RESULTS: Over median follow-up of 28 months, the risk of MACE was not associated with baseline HDLP (adjusted HR = 0.98, 95% CI = 0.84-1.15, P = .81), any HDLP subclass, or HDL-C. Dalcetrapib increased HDL-C and total, medium, and large HDLP and decreased small HDLP but had no effect on MACE compared with placebo. There were no association of risk of MACE with change in HDLP or HDL-C and no interaction with assigned study treatment. CONCLUSIONS: Neither baseline HDLP nor the change in HDLP on treatment with dalcetrapib or placebo was associated with risk of MACE after ACS.

Association of lipoprotein subfractions and glycoprotein acetylation with coronary plaque burden in SLE.

OBJECTIVE: Subjects with SLE display an enhanced risk of atherosclerotic cardiovascular disease (CVD) that is not explained by Framingham risk. This study sought to investigate the utility of nuclear MR (NMR) spectroscopy measurements of serum lipoprotein particle counts and size and glycoprotein acetylation (GlycA) burden to predict coronary atherosclerosis in SLE. METHODS: Coronary plaque burden was assessed in SLE subjects and healthy controls using coronary CT angiography. Lipoproteins and GlycA were quantified by NMR spectroscopy. RESULTS: SLE subjects displayed statistically significant decreases in high-density lipoprotein (HDL) particle counts and increased very low-density lipoprotein (VLDL) particle counts compared with controls. Non-calcified coronary plaque burden (NCB) negatively associated with HDL subsets whereas it positively associated with VLDL particle counts in multivariate adjusted models. GlycA was significantly increased in SLE sera compared with controls. In contrast to high-sensitivity C reactive protein, elevations in GlycA in SLE significantly associated with NCB and insulin resistance (IR), though the association with NCB was no longer significant after adjusting for prednisone use. CONCLUSIONS: Patients with SLE display a proatherogenic lipoprotein profile that may significantly contribute to the development of premature CVD. The results demonstrate that NMR measures of GlycA and lipoprotein profiles, beyond what is captured in routine clinical labs, could be a useful tool in assessing CVD risk in patients with SLE.

Association Between Aortic Vascular Inflammation and Coronary Artery Plaque Characteristics in Psoriasis.

Importance: Inflammation is critical to atherosclerosis. Psoriasis, a chronic inflammatory disease associated with early cardiovascular events and increased aortic vascular inflammation (VI), provides a model to study the process of early atherogenesis. Fludeoxyglucose F 18 positron emission tomography/computed tomography (18F-FDG PET/CT) helps quantify aortic VI, and coronary computed tomography angiography provides coronary artery disease (CAD) assessment through evaluation of total plaque burden (TB) and noncalcified coronary plaque burden (NCB), luminal stenosis, and high-risk plaques (HRP). To our knowledge, association between aortic VI and broad CAD indices has not yet been assessed in a chronic inflammatory disease state. Such a study may provide information regarding the utility of aortic VI in capturing early CAD. Objective: To assess the association between aortic VI and CAD indices, including TB, NCB, luminal stenosis, and HRP prevalence, in psoriasis. Design, Setting, and Participants: In a cross-sectional cohort study at the National Institutes of Health, 215 consecutive patients with psoriasis were recruited from surrounding outpatient dermatology practices. All patients underwent 18F-FDG PET/CT for aortic VI assessment, and 190 of 215 patients underwent coronary computed tomography angiography to characterize CAD. The study was conducted between January 1, 2013, and May 31, 2017. Data were analyzed in March 2018. Exposures: Aortic VI assessed by 18F-FDG PET/CT. Main Outcomes and Measures: Primary outcome: TB and NCB. Secondary outcomes: luminal stenosis and HRP. Results: Among 215 patients with psoriasis (mean [SD] age, 50.4 [12.6] years; 126 men [59%]), patients with increased aortic VI had increased TB (standardized ß = 0.48; P < .001), and higher prevalence of luminal stenosis (OR, 3.63; 95% CI, 1.71-7.70; P = .001) and HRP (OR, 3.05; 95% CI, 1.42-6.47; P = .004). The aortic VI and TB association was primarily driven by NCB (ß = 0.49; P < .001), whereas the aortic VI and HRP association was driven by low-attenuation plaque (OR, 5.63; 95% CI, 1.96-16.19; P = .001). All associations of aortic VI remained significant after adjustment for cardiovascular risk factors: aortic VI and TB (ß = 0.23; P < .001), NCB (ß = 0.24; P < .001), luminal stenosis (OR, 3.40; 95% CI, 1.40-8.24; P = .007), and HRP (OR, 2.72; 95% CI, 1.08-6.83; P = .03). No association was found between aortic VI and dense-calcified coronary plaque burden. Conclusions and Relevance: Aortic VI is associated with broad CAD indices, suggesting that aortic VI may be a surrogate for early CAD. Larger prospective studies need to assess these associations longitudinally and examine treatment effects on these outcomes.

Neutrophil subsets and their gene signature associate with vascular inflammation and coronary atherosclerosis in lupus.

BACKGROUND: Systemic lupus erythematosus (SLE) is associated with enhanced risk of atherosclerotic cardiovascular disease not explained by Framingham risk score (FRS). Immune dysregulation associated to a distinct subset of lupus proinflammatory neutrophils (low density granulocytes; LDGs) may play key roles in conferring enhanced CV risk. This study assessed if lupus LDGs are associated with in vivo vascular dysfunction and inflammation and coronary plaque. METHODS: SLE subjects and healthy controls underwent multimodal phenotyping of vascular disease by quantifying vascular inflammation (18F-fluorodeoxyglucose-PET/CT [18F-FDG-PET/CT]), arterial dysfunction (EndoPAT and cardio-ankle vascular index), and coronary plaque burden (coronary CT angiography). LDGs were quantified by flow cytometry. Cholesterol efflux capacity was measured in high-density lipoprotein-exposed (HDL-exposed) radioactively labeled cell lines. Whole blood RNA sequencing was performed to assess associations between transcriptomic profiles and vascular phenotype. RESULTS: Vascular inflammation, arterial stiffness, and noncalcified plaque burden (NCB) were increased in SLE compared with controls even after adjustment for traditional risk factors. In SLE, NCB directly associated with LDGs and associated negatively with cholesterol efflux capacity in fully adjusted models. A neutrophil gene signature reflective of the most upregulated genes in lupus LDGs associated with vascular inflammation and NCB. CONCLUSION: Individuals with SLE demonstrate vascular inflammation, arterial dysfunction, and NCB, which may explain the higher reported risk for acute coronary syndromes. The association of LDGs and neutrophil genes with vascular disease supports the hypothesis that distinct neutrophil subsets contribute to vascular damage and unstable coronary plaque in SLE. Results also support previous observations that neutrophils may disrupt HDL function and thereby promote atherogenesis. TRIAL REGISTRATION: Clinicaltrials.gov NCT00001372FUNDING.

Coronary Plaque Characterization in Psoriasis Reveals High-Risk Features That Improve After Treatment in a Prospective Observational Study.

BACKGROUND: Psoriasis, a chronic inflammatory disease associated with an accelerated risk of myocardial infarction, provides an ideal human model to study inflammatory atherogenesis in vivo. We hypothesized that the increased cardiovascular risk observed in psoriasis would be partially attributable to an elevated subclinical coronary artery disease burden composed of noncalcified plaques with high-risk features. However, inadequate efforts have been made to directly measure coronary artery disease in this vulnerable population. As such, we sought to compare total coronary plaque burden and noncalcified coronary plaque burden (NCB) and high-risk plaque (HRP) prevalence between patients with psoriasis (n=105), patients with hyperlipidemia eligible for statin therapy under National Cholesterol Education Program-Adult Treatment Panel III guidelines (n=100) who were ≈10 years older, and healthy volunteers without psoriasis (n=25). METHODS: Patients underwent coronary computed-tomography angiography for total coronary plaque burden and NCB quantification and HRP identification, defined as low attenuation (<30 hounsfield units), positive remodeling (>1.10), and spotty calcification. A consecutive sample of the first 50 patients with psoriasis was scanned again 1 year after therapy. RESULTS: Despite being younger and at lower traditional risk than patients with hyperlipidemia, patients with psoriasis had increased NCB (mean±SD: 1.18±0.33 versus 1.11±0.32, P=0.02) and similar HRP prevalence (P=0.58). Furthermore, compared to healthy volunteers, patients with psoriasis had increased total coronary plaque burden (1.22±0.31 versus 1.04±0.22, P=0.001), NCB (1.18±0.33 versus 1.03±0.21, P=0.004), and HRP prevalence beyond traditional risk (odds ratio, 6.0; 95% confidence interval, 1.1-31.7; P=0.03). Last, among patients with psoriasis followed for 1 year, improvement in psoriasis severity was associated with improvement in total coronary plaque burden (ß=0.45, 0.23-0.67; P<0.001) and NCB (ß=0.53, 0.32-0.74; P<0.001) beyond traditional risk factors. CONCLUSIONS: Patients with psoriasis had greater NCB and increased HRP prevalence than healthy volunteers. In addition, patients with psoriasis had elevated NCB and equivalent HRP prevalence as older patients with hyperlipidemia. Last, modulation of target organ inflammation (eg, skin) was associated with an improvement in NCB at 1 year, suggesting that control of remote sites of inflammation may translate into reduced coronary artery disease risk.

GlycA Is a Novel Biomarker of Inflammation and Subclinical Cardiovascular Disease in Psoriasis.

RATIONALE: GlycA, an emerging inflammatory biomarker, predicted cardiovascular events in population-based studies. Psoriasis, an inflammatory disease associated with increased cardiovascular risk, provides a model to study inflammatory biomarkers in cardiovascular disease (CVD). Whether GlycA associates with psoriasis and how it predicts subclinical CVD beyond high-sensitivity C-reactive protein in psoriasis is unknown. OBJECTIVE: To investigate the relationships between GlycA and psoriasis and between GlycA and subclinical CVD. METHODS AND RESULTS: Patients with psoriasis and controls (n=412) participated in a 2-stage study. We measured GlycA by nuclear magnetic resonance spectroscopy. National Institutes of Health (NIH) participants underwent 18-F Fluorodeoxyglucose Positron Emission Tomography Computed Tomography (18-FDG PET/CT) scans to assess vascular inflammation (VI) and coronary computed tomographic angiography to quantify coronary artery disease burden. Psoriasis cohorts were young (mean age=47.9), with low cardiovascular risk and moderate skin disease. high-sensitivity C-reactive protein and GlycA were increased in psoriasis compared with controls (GlycA: [PENN: 408.8±75.4 versus 289.4±60.2, P<0.0001; NIH: 415.8±63.2 versus 346.2±46, P<0.0001]) and demonstrated a dose-response with psoriasis severity. In stage 2, VI (ß=0.36, P<0.001) and coronary artery disease (ß=0.29, P=0.004) associated with GlycA beyond CV risk factors in psoriasis. In receiver operating characteristic analysis, GlycA added value in predicting VI (P=0.01) and coronary artery disease (P<0.01). Finally, initiating anti-tumor necrosis factor therapy (n=16) reduced psoriasis severity (P<0.001), GlycA (463.7±92.5 versus 370.1±78.5, P<0.001) and VI (1.93±0.36 versus 1.76±0.19, P<0.001), whereas GlycA remained associated with VI (ß=0.56, P<0.001) post treatment. CONCLUSIONS: GlycA associated with psoriasis severity and subclinical CVD beyond traditional CV risk and high-sensitivity C-reactive protein. Moreover, psoriasis treatment reduced GlycA and VI. These findings support the potential use of GlycA in subclinical CVD risk assessment in psoriasis and potentially other inflammatory diseases.

Self-reported depression in psoriasis is associated with subclinical vascular diseases.

BACKGROUND AND AIMS: Psoriasis is a chronic inflammatory disorder associated with vascular inflammation, measured by 18-fluorodeoxyglucose positron emission tomography/computed tomography (18-FDG PET/CT), and an increased risk of myocardial infarction. Patients with psoriasis are also more likely to suffer from comorbid depression. Whether depression accelerates the development of subclinical atherosclerosis in psoriasis is unknown. METHODS: Patients were selected from within a larger psoriasis cohort. Those who reported a history of depression (N = 36) on survey were matched by age and gender to patients who reported no history of psychiatric illness (N = 36). Target-to-background ratio from FDG PET/CT was used to assess aortic vascular inflammation and coronary CT angiography scans were analyzed to determine coronary plaque burden. Multivariable linear regression was performed to understand the effect of self-reported depression on vascular inflammation and coronary plaque burden after adjustment for Framingham risk (standardized ß reported). RESULTS: In unadjusted analyses, vascular inflammation and coronary plaque burden were significantly increased in patients with self-reported depression as compared to patients with psoriasis alone. After adjustment for Framingham Risk Score, vascular inflammation (ß = 0.26, p = 0.02), total plaque burden (ß = 0.17, p = 0.03), and non-calcified burden (ß = 0.17, p = 0.03) were associated with self-reported depression. CONCLUSIONS: Self-reported depression in psoriasis is associated with increased vascular inflammation and coronary plaque burden. Depression may play an important role in promoting subclinical atherosclerosis beyond traditional cardiovascular risk factors.

Atrial Fibrillation and Cardiovascular Outcomes in the Elderly.

BACKGROUND: Prior studies have not examined which cardiovascular outcomes most frequently develop in participants with atrial fibrillation (AF) from population-based cohorts of the elderly. METHODS: This analysis included 4,304 (85% white; 61% women) participants from the Cardiovascular Health Study who were free of baseline cardiovascular disease. AF cases were identified at baseline and as time-updated events during follow-up. Kaplan-Meier estimates were used to compute the 1-, 5-, 10-, and 15-year cumulative incidence rates of the following outcomes: coronary heart disease (CHD), myocardial infarction (MI), heart failure, and ischemic stroke. Cox regression was used to compute hazard ratios (HR) and 95% confidence intervals (CI) for the association between AF and each outcome. RESULTS: For all time periods, the cumulative incidence estimates of CHD, MI, heart failure, and ischemic stroke were higher for those with AF compared with those without AF. Heart failure was the most frequent outcome in those with AF, while CHD events were the most frequently detected outcome in participants without AF. Compared with persons who did not have AF, the risk of heart failure was higher in those with AF (HR = 3.18, 95% CI = 2.78-3.64), and the magnitude of this association was greater than the other outcomes of interest (CHD: HR = 1.76, 95% CI = 1.54-2.03; MI: 1.40, 95% CI = 1.14-1.71; ischemic stroke: HR = 1.98, 95% CI = 1.63-2.39). CONCLUSIONS: AF is associated with several adverse cardiovascular outcomes and heart failure is the most frequently detected event. Potentially, risk factor modification strategies for the primary prevention of heart failure will reduce the morbidity and mortality associated with AF.

The Influence of Left Atrial Enlargement on the Relationship between Atrial Fibrillation and Stroke.

BACKGROUND: Left atrial enlargement (LAE) is independently associated with an increased risk of stroke and atrial fibrillation (AF). The combination of both LAE and AF possibly increases the risk of stroke beyond that observed with AF. METHODS: This analysis included 4572 (43% men, 95% white) participants from the Cardiovascular Health Study. LAE was defined using transthoracic echocardiographic 2-dimensional M-mode measurements of the left atrial diameter using sex-specific cut-points (men: ≥4.1 cm, women: ≥3.9 cm). AF cases were identified during the initial study electrocardiogram or by self-reported history. We examined the association between baseline AF and incident ischemic stroke stratified by the presence of LAE. Incident cases of ischemic stroke were identified by adjudication of medical records, including hospitalization data, through December 31, 2010. RESULTS: At baseline, a total of 253 (5.5%) participants had AF and 1947 (43%) had LAE. Participants with AF (n = 163, 64%) were more likely to have LAE than those without AF (n = 1784, 41%; P < .001). Over a median follow-up of 13 years, 739 (16%) ischemic stroke events were identified. Both AF (hazard ratio [HR] = 2.12, 95% confidence interval [CI] = 1.64-2.74) and left atrial diameter (per 1-cm increase: HR = 1.14, 95% CI = 1.01-1.28) were associated with an increased risk for ischemic stroke. The association between AF and ischemic stroke was not modified by the presence of LAE (LAE: HR = 2.13, 95% CI = 1.42-3.19; no LAE: HR = 1.91, 95% CI = 1.36-2.68; P interaction = .86). CONCLUSION: Our results suggest that echocardiographic LAE does not modify the stroke risk observed with AF.

Peripheral arterial disease is associated with an increased risk of atrial fibrillation in the elderly.

AIMS: To examine the relationship between peripheral arterial disease (PAD) and atrial fibrillation (AF) in a population-based cohort study of older adults. METHODS AND RESULTS: We examined the relationship between PAD and AF in 5143 participants (85% white, 43% male) in the Cardiovascular Health Study (CHS), a longitudinal, observational study of adults aged 65 years and older. Peripheral arterial disease was defined by abnormal ankle-brachial index (ABI) values (<1.0 or >1.4). Incident AF events were ascertained by self-reported history, study electrocardiograms, and hospitalization discharge records. Cox regression was used to compute hazard ratios (HRs) and 95% confidence intervals (CIs) for the association between PAD and AF. Over a median follow-up of 11.7 years, a total of 1521 participants developed AF. The incidence rate (per 1000 person-years) of AF was higher in those with PAD (incidence rate = 32.9, 95% CI = 29.5, 36.7) than those without PAD (incidence rate = 23.3, 95% CI = 22.0, 24.6). In a multivariate Cox regression analysis, PAD was associated with an increased risk for AF (HR = 1.52, 95% CI = 1.34, 1.72). Each 0.1 decrease in the ABI was associated with a 6% increase in the risk for AF (HR = 1.06, 95% CI = 1.02, 1.10). The associations of high (>1.4) and low (<1.0) ABI values with AF were examined separately and were in the same direction as the main result for PAD (ABI < 1.0: HR = 1.24, 95% CI = 1.08, 1.42; ABI > 1.4: HR = 1.33, 95% CI = 0.95, 1.86). CONCLUSION: The presence of PAD should alert practitioners to the increased risk of AF. Elderly patients with PAD possibly will benefit from routine electrocardiographic screening to identify AF events.

Severity of Psoriasis Associates With Aortic Vascular Inflammation Detected by FDG PET/CT and Neutrophil Activation in a Prospective Observational Study.

OBJECTIVE: To understand whether directly measured psoriasis severity is associated with vascular inflammation assessed by (18)F-fluorodeoxyglucose positron emission tomography computed tomography. APPROACH: In-depth cardiovascular and metabolic phenotyping was performed in adult psoriasis patients (n=60) and controls (n=20). Psoriasis severity was measured using psoriasis area severity index. Vascular inflammation was measured using average aortic target-to-background ratio using (18)F-fluorodeoxyglucose positron emission tomography computed tomography. RESULTS: Both the psoriasis patients (28 men and 32 women, mean age 47 years) and controls (13 men and 7 women, mean age 41 years) were young with low cardiovascular risk. Psoriasis area severity index scores (median 5.4; interquartile range 2.8-8.3) were consistent with mild-to-moderate skin disease severity. Increasing psoriasis area severity index score was associated with an increase in aortic target-to-background ratio (ß=0.41, P=0.001), an association that changed little after adjustment for age, sex, and Framingham risk score. We observed evidence of increased neutrophil frequency (mean psoriasis, 3.7±1.2 versus 2.9±1.2; P=0.02) and activation by lower neutrophil surface CD16 and CD62L in blood. Serum levels of S100A8/A9 (745.1±53.3 versus 195.4±157.8 ng/mL; P<0.01) and neutrophil elastase-1 (43.0±2.4 versus 30.8±6.7 ng/mL; P<0.001) were elevated in psoriasis. Finally, S100A8/A9 protein was related to both psoriasis skin disease severity (ß=0.53; P=0.02) and vascular inflammation (ß=0.48; P=0.02). CONCLUSIONS: Psoriasis severity is associated with vascular inflammation beyond cardiovascular risk factors. Psoriasis increased neutrophil activation and neutrophil markers, and S100A8/A9 was related to both skin disease severity and vascular inflammation.

Cholesterol efflux capacity in humans with psoriasis is inversely related to non-calcified burden of coronary atherosclerosis.

AIMS: Cholesterol efflux capacity (CEC) was recently shown to predict future cardiovascular (CV) events. Psoriasis both increases CV risk and impairs CEC. However, whether having poor CEC is associated with coronary plaque burden is currently unknown. We aimed to assess the cross-sectional relationship between coronary plaque burden assessed by quantitative coronary computed tomography angiography (CCTA) with CEC in a well-phenotyped psoriasis cohort. METHODS AND RESULTS: Total burden and non-calcified burden (NCB) plaque indices were assessed in 101 consecutive psoriasis patients using quantitative software. Cholesterol efflux capacity was quantified using a cell-based ex vivo assay measuring the ability of apoB-depleted plasma to mobilize cholesterol from lipid-loaded macrophages. Cholesterol efflux capacity was inversely correlated with NCB (unadjusted ß-coefficient -0.33; P < 0.001), and this relationship persisted after adjustment for CV risk factors (ß -0.24; P < 0.001), HDL-C levels (ß -0.22; P < 0.001), and apoA1 levels (ß -0.19; P < 0.001). Finally, we observed a significant gender interaction (P < 0.001) whereby women with low CEC had higher NCB compared to men with low CEC. CONCLUSIONS: We show that CEC is inversely associated with prevalent coronary plaque burden measured by quantitative CCTA. Low CEC may therefore be an important biomarker for subclinical coronary atherosclerosis in psoriasis. CLINICALTRIALSGOV: NCT01778569.
