Location of acute coronary artery thromboses in patients with and without chronic kidney disease

Patients with chronic kidney disease have high rates of myocardial infarction and death following an initial attack. Proximal location of coronary atherosclerotic lesions has been linked to the risk of acute myocardial infarction and to infarction-associated mortality. To examine if the spatial distribution of lesions differs in patients with and without chronic kidney disease, we used quantitative coronary angiography to measure this in patients with acute coronary thromboses who were having angiography following acute myocardial infarction. Multivariable linear regression was used to adjust for differences in baseline characteristics. Among 82 patients with stage 3 or higher chronic kidney disease, 55.6% of lesions were located within 30 mm and 87.7% were within 50 mm of the coronary ostia. This compared to 34.7 and 71.8%, respectively, among 299 patients without significant kidney disease. Chronic kidney disease was independently and significantly associated with a 7.0 mm decrease in the distance from the coronary ostia to the problem lesion. Our study suggests that a causal link between a more proximal culprit lesion location in patients with chronic kidney disease and their high mortality rates after myocardial infarct is possible and may have important implications for interventions to prevent infarction

Cardiovascular Risk in Patients With Psoriasis: JACC Review Topic of the Week

Psoriasis is a chronic inflammatory skin disease that affects 2% to 3% of the U.S. population. The immune response in psoriasis includes enhanced activation of T cells and myeloid cells, platelet activation, and up-regulation of interferons, tumor necrosis factor-α, and interleukins (ILs) IL-23, IL-17, and IL-6, which are linked to vascular inflammation and atherosclerosis development. Patients with psoriasis are up to 50% more likely to develop cardiovascular disease (CV) disease, and this CV risk increases with skin severity. Major society guidelines now advocate incorporating a psoriasis diagnosis into CV risk prediction and prevention strategies. Although registry data suggest treatment targeting psoriasis skin disease reduces vascular inflammation and coronary plaque burden, and may reduce CV risk, randomized placebo-controlled trials are inconclusive to date. Further studies are required to define traditional CV risk factor goals, the optimal role of lipid-lowering and antiplatelet therapy, and targeted psoriasis therapies on CV risk

C-reactive protein and clinical outcomes in patients with COVID-19

BACKGROUND: A systemic inflammatory response is observed in coronavirus disease 2019 (COVID-19). Elevated serum levels of C-reactive protein (CRP), a marker of systemic inflammation, are associated with severe disease in bacterial or viral infections. We aimed to explore associations between CRP concentration at initial hospital presentation and clinical outcomes in patients with COVID-19. METHODS AND RESULTS: Consecutive adults aged ≥18 years with COVID-19 admitted to a large New York healthcare system between 1 March and 8 April 2020 were identified. Patients with measurement of CRP were included. Venous thrombo-embolism (VTE), acute kidney injury (AKI), critical illness, and in-hospital mortality were determined for all patients. Among 2782 patients hospitalized with COVID-19, 2601 (93.5%) had a CRP measurement [median 108 mg/L, interquartile range (IQR) 53-169]. CRP concentrations above the median value were associated with VTE [8.3% vs. 3.4%; adjusted odds ratio (aOR) 2.33, 95% confidence interval (CI) 1.61-3.36], AKI (43.0% vs. 28.4%; aOR 2.11, 95% CI 1.76-2.52), critical illness (47.6% vs. 25.9%; aOR 2.83, 95% CI 2.37-3.37), and mortality (32.2% vs. 17.8%; aOR 2.59, 95% CI 2.11-3.18), compared with CRP below the median. A dose response was observed between CRP concentration and adverse outcomes. While the associations between CRP and adverse outcomes were consistent among patients with low and high D-dimer levels, patients with high D-dimer and high CRP have the greatest risk of adverse outcomes. CONCLUSIONS: Systemic inflammation, as measured by CRP, is strongly associated with VTE, AKI, critical illness, and mortality in COVID-19. CRP-based approaches to risk stratification and treatment should be tested

Sex differences in the prevalence of vascular disease and risk factors in young hospitalized patients with psoriasis

© 2019 Background: Psoriasis is an inflammatory skin disease associated with atherosclerotic cardiovascular disease (ASCVD) risk factors and vascular disease. The relative impact of psoriasis on vascular disease is the strongest in young patients with psoriasis, yet data are lacking on how sex differences influence cardiovascular risk factors and vascular disease in these patients. Objective: This observational study aimed to identify the burden of cardiovascular risk factors and vascular disease in patients with psoriasis and to explore whether this burden is different between men and women age \u3c 35 years. Methods: Young (age ≥ 20 and \u3c 35 years) hospitalized patients with psoriasis from the United States National Inpatient Sample were compared with those matched patients without psoriasis. Vascular disease was defined as ASCVD and/or venous thromboembolic disease. Multivariable logistic regression was used to determine the associations between psoriasis, sex, ASCVD risk factors, and vascular disease. Results: Overall, patients with psoriasis (n = 18,353) were more often obese (16% vs. 6%); smokers (31% vs. 17%); and diagnosed with diabetes mellitus (10% vs. 6%), hypertension (16% vs. 8%), hyperlipidemia (6% vs. 2%), ASCVD (2.2% vs. 1.6%), and deep vein thrombosis (6% vs. 4%; all p \u3c.001) compared with patients without psoriasis (n = 55,059; matched by age, sex, and race). When stratified by sex, women with psoriasis were more likely to have multiple cardiovascular risk factors and ASCVD (odds ratio: 2.6; 95% confidence interval [2.1-3.1]) compared with men with psoriasis (odds ratio: 1.2; 95% confidence interval [0.9-1.4]; interaction p \u3c.01). The association between psoriasis and ASCVD in women remained unchanged after multivariable adjustment for traditional cardiovascular risk factors. Conclusion: Psoriasis was associated with cardiovascular disease and risk factors in young hospitalized patients, with stronger associations among women than among men

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. Summary: 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

Lipoprotein(a): Emerging insights and therapeutics

The strong association between lipoprotein (a) [Lp(a)] and atherosclerotic cardiovascular disease has led to considerations of Lp(a) being a potential target for mitigating residual cardiovascular risk. While approximately 20 % of the population has an Lp(a) level greater than 50 mg/dL, there are no currently available pharmacological lipid-lowering therapies that have demonstrated substantial reduction in Lp(a). Novel therapies to lower Lp(a) include antisense oligonucleotides and small-interfering ribonucleic acid molecules and have shown promising results in phase 2 trials. Phase 3 trials are currently underway and will test the causal relationship between Lp(a) and ASCVD and whether lowering Lp(a) reduces cardiovascular outcomes. In this review, we summarize emerging insights related to Lp(a)’s role as a risk-enhancing factor for ASCVD, association with calcific aortic stenosis, effects of existing therapies on Lp(a) levels, and variations amongst patient populations. The evolving therapeutic landscape of emerging therapeutics is further discussed

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

© 2020 American Academy of Dermatology, Inc. 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 \u3c.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 (β = 1.71; P =.02). In nested models, CCL20 added value (χ2 = 79.22; P \u3c.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 \u3c.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
