Burden of cardiometabolic risk factors and vascular health.

BACKGROUND: Cardiometabolic risk factors diabetes, obesity, and hypertension are highly prevalent and contribute to increased cardiovascular disease (CVD). Endothelial dysfunction precedes CVD development. The current study aimed to investigate the EC transcriptome among individuals with varying degree of cardiometabolic risk. METHODS: Adult participants without CVD and various degrees of cardiometabolic risk factor burden (hypertension, diabetes, obesity) were included. Participants underwent brachial vein EC harvesting followed by RNA sequencing. To evaluate the association between cardiometabolic comorbidity burden and outcome transcripts we performed linear regression with multivariable models, adjusting for age, sex, and race/ethnicity. RESULTS: A total of 18 individuals were included in the present analysis (mean age 47 ± 14, 44% female, and 61% White adults). Endothelial cell RNA sequencing revealed 588 differentially expressed transcripts (p-adj <0.05) with excellent discrimination in unsupervised hierarchical clustering analysis. Gene ontology enrichment analysis revealed upregulated pathways associated with T-cell activation (NES = 2.22, p<0.001), leukocyte differentiation (NES= 2.16, p<0.001), leukocyte migration (NES= 2.12, p<0.001), regulation of cell-cell adhesion (NES= 1.91, p=0.006). Downregulated pathways of interest included endothelial cell proliferation (NES= -1.68, p=0.03) and response to interleukin-1 (NES= -1.61, p=0.04). Upregulated genes included VCAM1, CEACAM1, ADAM 17, and CD99L2, all with a log-2-fold change >3 and p-adj <0.05. These genes demonstrated a graded increase in mean normalized counts with increasing number of risk factors. CONCLUSIONS: We demonstrate a proinflammatory and pro-adhesive EC transcriptome associated with increased cardiometabolic risk factor burden offering insight into a potential mechanism linking these risk factors with the development of CVD.

Colchicine for the Prevention of Cardiovascular Disease: Potential Global Implementation.

PURPOSE OF REVIEW: Targeting traditional cardiovascular risk factors is effective in reducing recurrent cardiovascular events, yet the presence of residual cardiovascular risk due to underlying systemic inflammation is a largely unaddressed opportunity. This review aims to comprehensively assess the evolving role of colchicine as a therapeutic approach targeting residual inflammatory risk in the context of those with coronary artery disease (CAD). RECENT FINDINGS: Inflammation plays a significant role in promoting atherosclerosis, and targeting anti-inflammatory pathways has the potential to decrease cardiovascular events. Low-dose colchicine (0.5 mg/day orally), when added to guideline-directed medical care for CAD, safely decreases major adverse cardiovascular events (MACE) by 31% in stable atherosclerosis patients and 23% in those after recent myocardial infarctions. Meta-analyses of recent randomized control trials further support both the efficacy and safety of colchicine, particularly when added to other standard cardiovascular therapies, including statin therapy. The European Society of Cardiology and other national guidelines endorse the use of low-dose colchicine in patients across the spectrum of CAD. Recently, colchicine was FDA-approved in the United States as the first anti-inflammatory therapy for the reduction of cardiovascular events. In a period of a rising incidence of CAD across the globe, colchicine represents a unique opportunity to decrease MACE due to its large magnitude of benefits and general affordability. However, challenges with drug interactions must be addressed, especially in those regions where HIV, hepatitis, and tuberculosis are prevalent. Colchicine is safe and effective at reducing cardiovascular events across a broad spectrum of coronary syndromes. The ability to simultaneously target traditional risk factors and mitigate residual inflammatory risk marks a substantial advancement in cardiovascular prevention strategies, heralding a new era in the global battle against CAD.

Cardiovascular Risk Management in Patients Treated with JAK Inhibitors.

ABSTRACT: The Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway plays a critical role in the pathogenesis of many immune-mediated inflammatory diseases (IMIDs). Although Janus kinase inhibitors (JAKi) are an effective treatment for several IMIDs, they have come under scrutiny as a class due to a potential risk of venous thromboembolism (VTE) and cardiovascular (CV) events, specifically noted with the oral JAKi, tofacitinib, as reported in the ORAL Surveillance Trial of a high CV risk rheumatoid arthritis population. This trial resulted in a black box warning from the Food and Drug Administration and European Medicines Agency regarding risk of VTE and CV events that was extended across several types of JAKi (including topical ruxolitinib) when treating IMIDs, leading to considerable controversy. Included is an up-to-date review of the current and rapidly evolving literature on CV risk in patients with IMIDs on JAKi therapy, including identification of potential risk factors for future VTE and CV events on JAKi therapy. We suggest a comprehensive, multimodal, and systematic approach for evaluation of CV risk in patients considering taking JAKi and emphasize that cardiologists play an important role in risk stratification and mitigation for patients with high CV risk factors or on long-term JAKi therapies.

Evaluation and management of pericarditis in rheumatic diseases.

ABSTRACT: This review summarizes the evaluation for underlying rheumatic conditions in patients presenting with acute pericarditis, treatment considerations for specific rheumatic conditions, and the role of imaging in diagnosis and monitoring. Pericarditis may be one of the initial presentations of a rheumatic disease or identified in a patient with known rheumatic disease. There is also growing evidence for using anti-inflammatory and immunosuppressive agents for treating recurrent pericarditis, which can overlap with the treatment of rheumatic diseases.

An inflammatory transcriptomic signature in psoriasis associates with future cardiovascular events.

BACKGROUND: Psoriasis is an inflammatory skin disease associated with increased cardiovascular (CV) risk, whose pathogenesis is not fully known. OBJECTIVE: We identified a transcriptomic signature in psoriasis and investigated its association with prevalent and future risk of a CV event to understand the connection between psoriasis and CV disease (CVD). METHODS: Psoriasis patients (n = 37) with a history of moderate-severe skin disease without CVD and 11 matched controls underwent whole blood RNA sequencing. This transcriptomic signature in psoriasis versus controls was evaluated in two CVD cohorts: Women referred for cardiac catheterization with (n = 76) versus without (n = 97) myocardial infarction (MI), and patients with peripheral artery disease (n = 106) followed over 2.5 years for major adverse CV or limb events (MACLE). The association between genes differentially expressed in psoriasis and prevalent and incident CV events was assed. RESULTS: In psoriasis, median age was 44 (IQR; 34-51) years, 49% male and ACC/AHA ASCVD Risk Score of 1.0% (0.6-3.4) with no significant difference versus controls. The median psoriasis area and severity index score (PASI) was 4.0 (IQR 2.9-8.2) with 36% on biologic therapy. Overall, 247 whole blood genes were upregulated and 228 downregulated in psoriasis versus controls (p < 0.05), and 1302 genes positively and 1244 genes negatively correlated with PASI (p < 0.05). Seventy-three genes overlapped between psoriasis prevalence and PASI with key regulators identified as IL-6, IL-1ß and interferon gamma. In the CVD cohorts, 50 of 73 genes (68%) identified in psoriasis associated with prevalent MI, and 29 (40%) with incident MACLE. Key regulator transcripts identified in psoriasis and CVD cohorts included SOCS3, BCL3, OSM, PIM2, PIM3 and STAT5A. CONCLUSIONS: A whole blood transcriptomic signature of psoriasis diagnosis and severity associated with prevalent MI and incident MACLE. These data have implications for better understanding the link between psoriasis, systemic inflammation and CVD.

Ustekinumab reduces serum protein levels associated with cardiovascular risk in psoriasis vulgaris.

Psoriasis increases the risk of cardiovascular disease (CVD). Biomarkers for cardiovascular (CV) risk stratification in psoriasis are lacking, and the effects of psoriasis biologics on CV risk reduction remain unclear. The goal of this study was to identify biomarkers of CV risk in psoriasis blood that are reduced by ustekinumab. We quantified 276 inflammatory and CV-related serum proteins with Olink's multiplex assay in 10 psoriasis patients (vs. 18 healthy controls) and after 12 weeks of ustekinumab treatment. For each protein down-regulated after treatment, the literature was reviewed for studies assessing the protein's association with CVD. Data were collected from each study to calculate CV risk thresholds for each protein, which were compared with protein levels in psoriasis patients before and after treatment. Our results showed that 43 out of 276 proteins were down-regulated after treatment, 25 of which were initially up-regulated at baseline (vs. controls, all p-values ≤0.1). 8 down-regulated proteins were initially elevated above thresholds associated with enhanced CV risk in the literature (myeloperoxidase, C-X-C motif chemokine 10, E-selectin, interleukin-6, cystatin B, von Willebrand factor, tumor necrosis factor receptor 1 and N-terminal prohormone brain natriuretic peptide). Treatment lowered these proteins to below their risk thresholds, except for IL-6, which was lowered but remained at its risk threshold despite successful psoriasis skin treatment. In summary, 12 weeks of ustekinumab treatment reduced serum proteins present at levels associated with CV risk in psoriasis patients. Further studies can evaluate these proteins as potential ustekinumab-modulated biomarkers of CV risk in psoriasis and the impact of ustekinumab on CV risk reduction.

Psoriasis and Cardiovascular Disease: Novel Mechanisms and Evolving Therapeutics.

PURPOSE OF REVIEW: Psoriasis is a chronic inflammatory skin condition that is associated with increased cardiovascular risk compared to those without psoriasis. This review will cover emerging mechanisms of cardiovascular risk, key pathways targeted with biologic therapies, and the current evidence on therapies to modulate this risk in patients with psoriasis. RECENT FINDINGS: Recent scientific work has highlighted mechanisms that contribute to this enhanced risk, including the role of vascular endothelial dysfunction, platelet activation, dyslipidemia, and increased cardiometabolic comorbidities. Newer biologic and targeted synthetic therapies have transformed psoriasis treatment with high rates of clinical remission and durable skin disease control now possible. Epidemiological evidence suggests that many of these therapies may lower cardiovascular risk in psoriasis, although prospective interventional data is lacking (or mixed). Recently, caution has also been raised that some treatments may negatively affect cardiovascular risk. Overall, the current data suggests a positive or neutral ability to reduce cardiovascular risk for TNF, IL-17A, and IL-12/23p40 inhibitors, but current evidence remains conflicting for anti-IL-23/p19 and JAK inhibitors. More studies that include prospective cohorts, larger number of patients, treatment duration, and validated surrogate outcomes are needed to better evaluate the role of biologic therapies on cardiovascular risk in psoriasis.

COVID-19 and the Heart and Vasculature: Novel Approaches to Reduce Virus-Induced Inflammation in Patients With Cardiovascular Disease.

The coronavirus disease 2019 (COVID-19) pandemic presents an unprecedented challenge and opportunity for translational investigators to rapidly develop safe and effective therapeutic interventions. Greater risk of severe disease in COVID-19 patients with comorbid diabetes mellitus, obesity, and heart disease may be attributable to synergistic activation of vascular inflammation pathways associated with both COVID-19 and cardiometabolic disease. This mechanistic link provides a scientific framework for translational studies of drugs developed for treatment of cardiometabolic disease as novel therapeutic interventions to mitigate inflammation and improve outcomes in patients with COVID-19.

Activated Platelets Induce Endothelial Cell Inflammatory Response in Psoriasis via COX-1.

OBJECTIVE: Patients with psoriasis have impaired vascular health and increased cardiovascular disease (CVD). Platelets are key players in the pathogenesis of vascular dysfunction in cardiovascular disease and represent therapeutic targets in cardiovascular prevention. The object of this study was to define the platelet phenotype and effector cell properties on vascular health in psoriasis and evaluate whether aspirin modulates the platelet-induced phenotype. Approach and Results: Platelets from psoriasis patients (n=45) exhibited increased platelet activation (relative to age- and gender-matched controls, n=18), which correlated with psoriasis skin severity. Isolated platelets from psoriasis patients demonstrated a 2- to 3-fold (P<0.01) increased adhesion to human aortic endothelial cells and induced proinflammatory transcriptional changes, including upregulation of IL 8 (interleukin 8), IL1ß, and Cox (cyclooxygenase)-2 Platelet RNA sequencing revealed an interferon signature and elevated expression of COX-1, which correlated with psoriasis disease severity (r=0.83, P=0.01). In a randomized trial of patients with psoriasis, 2 weeks of 81 mg low-dose aspirin, a COX-1 inhibitor, reduced serum thromboxane (Tx) B2 and reduced brachial vein endothelial proinflammatory transcript expression >70% compared with the no-treatment group (P<0.01). Improvement in brachial vein endothelial cell inflammation significantly correlated with change in serum TxB2 (r=0.48, P=0.02). CONCLUSIONS: In patients with psoriasis, platelets are activated and induce endothelial cell inflammation. Low-dose aspirin improved endothelial cell health in psoriasis via platelet COX-1 inhibition. These data demonstrate a previously unappreciated role of platelets in psoriasis and endothelial cell inflammation and suggests that aspirin may be effective in improving vascular health in patients with psoriasis.

CCL20 in psoriasis: A potential biomarker of disease severity, inflammation, and impaired vascular health.

BACKGROUND: Psoriasis is associated with increased cardiovascular risk that is not captured by traditional proinflammatory biomarkers. OBJECTIVE: To investigate the relationship between Psoriasis Area and Severity Index, circulating proinflammatory biomarkers, and vascular health in psoriasis. METHODS: In patients with psoriasis and in age and sex-matched controls, 273 proteins were analyzed with the Proseek Multiplex Cardiovascular disease reagents kit and Inflammatory reagents kit (Olink Bioscience), whereas vascular endothelial inflammation and health were measured via direct transcriptomic analysis of brachial vein endothelial cells. RESULTS: In psoriasis, chemokine ligand 20 (CCL20), interleukin (IL) 6, and IL-17A were the top 3 circulating proinflammatory cytokines. Vascular endothelial inflammation correlated with CCL20 (r = 0.55; P < .001) and less so with IL-6 (r = 0.36; P = .04) and IL-17A (r = 0.29; P = .12). After adjustment for potential confounders, the association between CCL20 and vascular endothelial inflammation remained significant (ß = 1.71; P = .02). In nested models, CCL20 added value (χ2 = 79.22; P < .001) to a model already incorporating the Psoriasis Area and Severity Index, Framingham risk, high-sensitivity C-reactive protein, Il-17A, and IL-6 (χ2 = 48.18; P < .001) in predicting vascular endothelial inflammation. LIMITATIONS: Our study was observational and did not allow for causal inference in the relationship between CCL20 and cardiovascular risk. CONCLUSION: We demonstrate that CCL20 expression has a strong association with vascular endothelial inflammation, reflects systemic inflammation, and may serve as a potential biomarker of impaired vascular health in psoriasis.

Aortic closure signal length on doppler echocardiography differentiates aortic patient-prosthesis mismatch from prosthetic stenosis.

PURPOSE: The purpose of this study was to investigate the diagnostic potential of the aortic closure (A2) signal length on Doppler echocardiography in distinguishing aortic patient-prosthesis mismatch (PPM) from prosthetic stenosis among patients with elevated gradients over bioprosthetic valves. METHODS: The A2 signal length was retrospectively measured for 150 patients with bioprosthetic aortic valves (50 with PPM, 50 with prosthetic stenosis, and 50 with normally functioning valves) from transthoracic echocardiograms performed at NYU Langone Health between 01/01/2012 and 08/01/2018. RESULTS: Mean A2 signal length was shorter among patients with PPM (11.1 ms ± 5.2 ms), than among those with prosthetic stenosis (21.1 ms ± 6.0 ms), P < .001 and controls (21.7 ms ± 7.4 ms), P < .001. There was no difference in A2 signal length between prosthetic stenosis and controls. The A2 signal length yielded an AUC of 0.89 (95% CI 0.82-0.95) for predicting PPM over prosthetic stenosis. CONCLUSION: Among patients with bioprosthetic aortic valves, the length of the A2 signal on Doppler echocardiography is shorter in PPM than in prosthetic stenosis and normally functioning valves. The A2 signal length may represent a novel metric to distinguish PPM from prosthetic stenosis.

Apolipoprotein AI) Promotes Atherosclerosis Regression in Diabetic Mice by Suppressing Myelopoiesis and Plaque Inflammation.

BACKGROUND: Despite robust cholesterol lowering, cardiovascular disease risk remains increased in patients with diabetes mellitus. Consistent with this, diabetes mellitus impairs atherosclerosis regression after cholesterol lowering in humans and mice. In mice, this is attributed in part to hyperglycemia-induced monocytosis, which increases monocyte entry into plaques despite cholesterol lowering. In addition, diabetes mellitus skews plaque macrophages toward an atherogenic inflammatory M1 phenotype instead of toward the atherosclerosis-resolving M2 state typical with cholesterol lowering. Functional high-density lipoprotein (HDL), typically low in patients with diabetes mellitus, reduces monocyte precursor proliferation in murine bone marrow and has anti-inflammatory effects on human and murine macrophages. Our study aimed to test whether raising functional HDL levels in diabetic mice prevents monocytosis, reduces the quantity and inflammation of plaque macrophages, and enhances atherosclerosis regression after cholesterol lowering. METHODS: Aortic arches containing plaques developed in Ldlr-/- mice were transplanted into either wild-type, diabetic wild-type, or diabetic mice transgenic for human apolipoprotein AI, which have elevated functional HDL. Recipient mice all had low levels of low-density lipoprotein cholesterol to promote plaque regression. After 2 weeks, plaques in recipient mouse aortic grafts were examined. RESULTS: Diabetic wild-type mice had impaired atherosclerosis regression, which was normalized by raising HDL levels. This benefit was linked to suppressed hyperglycemia-driven myelopoiesis, monocytosis, and neutrophilia. Increased HDL improved cholesterol efflux from bone marrow progenitors, suppressing their proliferation and monocyte and neutrophil production capacity. In addition to reducing circulating monocytes available for recruitment into plaques, in the diabetic milieu, HDL suppressed the general recruitability of monocytes to inflammatory sites and promoted plaque macrophage polarization to the M2, atherosclerosis-resolving state. There was also a decrease in plaque neutrophil extracellular traps, which are atherogenic and increased by diabetes mellitus. CONCLUSIONS: Raising apolipoprotein AI and functional levels of HDL promotes multiple favorable changes in the production of monocytes and neutrophils and in the inflammatory environment of atherosclerotic plaques of diabetic mice after cholesterol lowering and may represent a novel approach to reduce cardiovascular disease risk in people with diabetes mellitus.

Inflammasome Signaling and Impaired Vascular Health in Psoriasis.

Objective- Psoriasis is an inflammatory skin disease which heightens the risk of cardiovascular disease. This study directly investigated vascular endothelial health and systemically altered pathways in psoriasis and matched controls. Approach and Results- Twenty patients (mean age, 40 years; 50% male) with active psoriasis and 10 age-, sex-matched controls were recruited. To investigate systemically alerted pathways, a deep sequencing omics approach was applied, including unbiased blood transcriptomic and targeted proteomic analysis. Vascular endothelial health was assessed by transcriptomic profiling of endothelial cells obtained from the brachial veins of recruited participants. Blood transcriptomic profiling identified inflammasome signaling as the highest differentially expressed canonical pathway ( Z score 1.6; P=1×10-7) including upregulation of CASP5 and interleukin ( IL) -1ß. Proteomic panels revealed IL-6 as a top differentially expressed cytokine in psoriasis with pathway analysis highlighting IL-1ß ( Z score 3.7; P=1.02×10-23) as an upstream activator of the observed upregulated proteins. Direct profiling of harvested brachial vein endothelial cells demonstrated inflammatory transcript (eg, IL-1ß, CXCL10, VCAM-1, IL-8, CXCL1, Lymphotoxin beta, ICAM-1, COX-2, and CCL3) upregulation between psoriasis versus controls. A linear relationship was seen between differentially expressed endothelial inflammatory transcripts and psoriasis disease severity. IL-6 levels correlated with inflammatory endothelial cell transcripts and whole blood inflammasome-associated transcripts, including CASP5 and IL-1ß. Conclusions- An unbiased sequencing approach demonstrated the inflammasome as the most differentially altered pathway in psoriasis versus controls. Inflammasome signaling correlated with psoriasis disease severity, circulating IL-6, and proinflammatory endothelial transcripts. These findings help better explain the heightened risk of cardiovascular disease in psoriasis. Clinical Trial Registration- URL: http://www.clinicaltrials.gov . Unique identifier: NCT03228017.

Cardiovascular Risk Factor Control and Lifestyle Factors in Young to Middle-Aged Adults with Newly Diagnosed Obstructive Coronary Artery Disease.

BACKGROUND: While progress in the prevention of cardiovascular disease (CVD) has been noted over the past several decades, there are still those who develop CVD earlier in life than others. OBJECTIVE: We investigated traditional and lifestyle CVD risk factors in young to middle-aged patients compared to older ones with obstructive coronary artery disease (CAD). METHODS: A retrospective analysis of patients with a new diagnosis of obstructive CAD undergoing coronary intervention was performed. Young to middle-aged patients were defined as those in the youngest quartile (n = 281, mean age 50 ± 6 years, 81% male) compared to the other three older quartiles combined (n = 799, mean age 69 ± 7.5 years, 71% male). Obstructive CAD was determined by angiography. RESULTS: Young to middle-aged patients compared to older ones were more likely to be male (p < 0.01), smokers (21 vs. 9%, p < 0.001), and have a higher body mass index (31 ± 6 vs. 29 ± 6 kg/m2, p < 0.001). Younger patients were less likely to eat fruits, vegetables, and fish and had fewer controlled CVD risk factors (2.7 ± 1.2 vs. 3.0 ± 1.0, p < 0.001). Compared to older patients, higher levels of psychological stress (aOR 1.6, 95% CI 1.1-2.4), financial stress (aOR 1.8, 95% CI 1.3-2.5), and low functional capacity (aOR 3.3, 95% CI 2.4-4.5) were noted in the young to middle-aged population as well. CONCLUSION: Lifestyle in addition to traditional CVD risk factors should be taken into account when evaluating risk for development of CVD in a younger population.

Average e' velocity on transthoracic echocardiogram is a novel predictor of left atrial appendage sludge or thrombus in patients with atrial fibrillation.

BACKGROUND: Studies have demonstrated the value of transthoracic echocardiogram (TTE) diastolic parameters in predicting left atrial appendage (LAA) thrombus; however, these studies have been small. We aim to clarify the relationship between TTE diastolic parameters, in particular average e', and LAA thrombus or sludge. METHODS: A case-control review was conducted of subjects with non-valvular atrial fibrillation (n = 2263) who had undergone TEE (transesophageal echocardiogram) and had a TTE within 1 year of TEE. Cases of LAA sludge or thrombus were matched to controls by age, sex, left ventricular ejection fraction (LVEF), and anticoagulation status. RESULTS: Forty-three subjects (mean age 73 ± 12, 65% male, LVEF 47%, 44% on anticoagulation) with LAA sludge or thrombus were identified. Compared to matched controls, average TTE e' (7.3 ± 2.1 cm/s vs 8.7 ± 2.1 cm/s, P < 0.001) and the E:e' ratio (15 ± 7 cm/s vs 12 ± 5 cm/s; P = 0.005) were significant predictors of LAA sludge or thrombus. Average TTE e' value of >11 cm/s had 100% sensitivity for ruling out LAA sludge or thrombus. CONCLUSION: In individuals with atrial fibrillation, average e' >11 cm/s on TTE is a promising independent predictor of the absence of LAA sludge or thrombus on TEE.

Cardiovascular and Venous Thromboembolic Risk With JAK Inhibitors in Immune-Mediated Inflammatory Skin Diseases: A Systematic Review and Meta-Analysis.

Importance: Janus kinase (JAK) inhibitors are an effective treatment option for patients with certain skin-related conditions, such as atopic dermatitis, alopecia areata, and vitiligo, but there is a current US Food and Drug Administration (FDA) boxed warning label for oral and topical JAK inhibitors regarding increased risk of major adverse cardiovascular events (MACE), venous thromboembolism (VTE), serious infections, malignant neoplasm, and death. However, this boxed warning was precipitated by results of the Oral Rheumatoid Arthritis Trial (ORAL) Surveillance study, which only included patients with rheumatoid arthritis, and the same association may not be observed in dermatologic conditions. Objective: To determine the risk of all-cause mortality, MACE, and VTE with JAK inhibitors in patients with dermatologic conditions. Data Sources: PubMed and ClinicalTrials.gov were searched from database inception to April 1, 2023. Study Selection: This review included phase 3 randomized clinical trials with a placebo/active comparator group of JAK inhibitors used for a dermatologic indication with FDA approval or pending approval or with European Union or Japanese approval. Studies without a comparison group, case reports, observational studies, and review articles were excluded. Data Extraction and Synthesis: This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Adverse events using odds ratios (ORs) and 95% CIs were calculated using a random-effects model and the DerSimonian-Laird method. Studies were screened, data abstracted, and quality assessed by 2 independent authors. The protocol was prospectively registered with PROSPERO. Main Outcomes and Measures: Primary outcomes were a composite of adjudicated MACE and all-cause mortality, and VTE. Results: The analysis included 35 randomized clinical trials with 20 651 patients (mean [SD] age, 38.5 [10.1] years; male, 54%) and a mean (SD) follow-up time of 4.9 (2.68) months. Findings did not show a significant difference between JAK inhibitors and placebo/active comparator in composite MACE and all-cause mortality (OR, 0.83; 95% CI, 0.44-1.57) or VTE (OR, 0.52; 95% CI, 0.26-1.04). Conclusions and Relevance: In this systematic review and meta-analysis, use of JAK inhibitors was not associated with increased risk of all-cause mortality, MACE, and VTE compared to the placebo/active comparator groups. Additional trials with long-term follow-up are needed to better understand the safety risks of JAK inhibitors used for dermatologic indications.

Angiographic characteristics of coronary arterial segments progressing to myocardial infarction in patients with and without chronic kidney disease.

BACKGROUND: Individuals with chronic kidney disease (CKD) have high rates of myocardial infarction (MI), but whether the nature of coronary lesions susceptible to plaque rupture is altered and whether the high rate of MI is related to a greater burden of atherosclerotic lesions in individuals with CKD is uncertain. METHODS: We used quantitative coronary angiography to assess atherosclerotic plaque location and characteristics at baseline and at the time of MI in 62 patients with and without CKD. Univariate and multivariable conditional logistic regression models were used to assess whether the association between pre-MI angiographic findings and MI differs in individuals with and without CKD. RESULTS: The risk of MI rose as the distance from the coronary ostium decreased both in patients with CKD (odds ratio per 10 mm 0.92 [95 % CI 0.87-0.99]) and in those without CKD (odds ratio 0.83 [95 % CI 0.75-0.93]). Although tighter degrees of coronary stenosis were associated with increased risks of MI in patients with and without CKD, the majority of MIs (70.9 % in patients with CKD and 89.5 % in those without CKD) occurred in segments with <50 % diameter stenosis at baseline. CONCLUSIONS: The characteristics of lesions progressing to MI are similar in individuals with and without CKD and the majority of events occur in areas with <50 % stenosis at baseline. Given the high burden of non-stenotic lesions in patients with CKD, an interventional strategy aimed solely at sites with high-grade stenosis is unlikely to markedly reduce the risk of MI in patients with CKD.

Autoimmune diseases and cardiovascular risk.

There are more than 80 different autoimmune diseases which collectively affect 4-8% of the world's population. In a recent study published in Lancet, Conrad et al. found that 19 autoimmune diseases are associated with a composite of cardiovascular disease (CVD). Inflammation promotes atherosclerotic CVD with psoriasis and rheumatoid arthritis recognized as CVD risk enhancers. New strategies are needed to identify and mitigate the impact of chronic inflammation on CVD-related morbidity and mortality.
