Increased risk of acute myocardial infarction and mortality in patients with systemic lupus erythematosus: Two nationwide retrospective cohort studies

Increased cardiovascular risk in Korean patients with systemic lupus erythematosus: a population-based cohort study

To determine the increased risk of major adverse cardiovascular events (MACE) in patients with systemic lupus erythematosus (SLE) compared to the general population in Korea. Using data from the National Health Insurance Service database spanning 2008 to 2018, incident SLE patients aged 18 years and above were selected along with a 1:4 age- and sex-matched control group. The crude incidence rate (IR) of MACE was calculated as the number of events per 1000 person-years and the IR ratio (IRR) for MACE was adjusted using generalized estimating equations. Subgroup analysis was conducted to evaluate the risk differences of overall MACE and its composites based on age and sex stratification. The study included 8568 SLE patients and 34,272 controls. The cumulative IR of MACE per 1000 person-years in SLE patients and controls were 4.08 and 1.30, respectively. After adjusting for confounders, SLE patients had a higher risk of MACE compared to the general population (adjusted IRR of 2.40 [95% confidence interval [CI] 1.88-3.05]), with no gender differences observed. The increased risk of MACE in SLE patients was highest in the 18-39 age group (IRR 11.70, 95% CI 5.95-23.01) and gradually decreased with age. The increased risk of ischemic stroke (IRR 2.41, 95% CI 1.84-3.15) and myocardial infarction (IRR 2.19, 95% CI 1.30-3.68) in SLE patients was comparable. The risk of MACE in SLE patients is 2.40 times higher than that of the general population, with a higher relative risk observed in younger individuals.

Hypertension in connective tissue disease

It is well documented that connective tissue disease (CTD) is a type of autoimmune disease characterized by chronic inflammation, which can occur across various organ systems throughout the whole body. Although the clinical manifestations of CTD are different, studies have shown that different CTD diseases have similar pathogenesis, implying that different CTD diseases may have similar clinical outcomes. Recent population-based studies have demonstrated an increased risk of cardiovascular disease (CVD) in patients with CTD compared with the control group, which is partially attributed to traditional cardiovascular risk factors, such as hypertension (HT), and that controlling the patients' blood pressure (BP) still constitutes one of the most effective means to prevent CVD. Although many studies have shown that the prevalence of HT in patients with CTD is higher than that in the general population, there is a lack of adequate data on the possible pathogenesis of HT. Also, the factors that promote the rise of BP, especially the relationship between connective tissue disease- hypertension (CTD-HT) and traditional cardiovascular risk factors (aging, sex, race, dyslipidemia, diabetes mellitus, smoking, obesity, etc.), have not been fully confirmed. In this review, we explore the mechanisms that might lead to elevated BP in patients with CTD and the factors that contribute to elevated BP and the management of CTD-HT, and we focus on whether traditional cardiovascular risk factors, the disease, and the presence of related therapeutic drugs are associated with an increased risk of HT in patients with CTD.

Atherosclerosis in Systemic Lupus Erythematosus

PURPOSE OF THE REVIEW

Systemic lupus erythematosus (SLE) patients are at increased risk of cardiovascular disease (CVD) compared to the general population, despite most patients being young females, who are not classically considered to be at high risk for cardiovascular disease using traditional risk assessment tools. The purpose of this review is to discuss the pathophysiology of atherosclerosis in SLE and raise awareness of the relationship between SLE and CVD.

RECENT FINDINGS

The increased risk of CVD in SLE patients is multifactorial, due to proatherogenic lipid profiles, immune dysregulation and inflammation, side effects of lupus treatment, and microvascular dysfunction. Conventional CV risk models often underperform in the identification of SLE patients at high risk of atherosclerosis. The use of non-invasive imaging serves as a strategy to identify patients with evidence of subclinical CVD and in the evaluation of symptomatic patients. Identification of subclinical atherosclerosis allows for aggressive management of CV risk factors. SLE patients experience an increased risk of atherosclerotic CVD, which is not solely explained by traditional CV risk factors. It is imperative that clinicians are aware of this association to implement prompt detection and treatment of atherosclerotic CVD in SLE patients.

Factors associated with cardiovascular events in systemic lupus erythematosus in a monocentric cohort with up to 40 years of follow-up

OBJECTIVES

Systemic lupus erythematosus (SLE) is associated with an increased cardiovascular risk. Several traditional and disease-specific risk factors have been shown to correlate with the occurrence of cardiovascular events (CVE) in patients with SLE. However, results of previous studies are diverse. The objectives of this study were to report number, type and those factors associated with CVE in patients with SLE in a large, single-center, ethnically diverse cohort with a long follow-up duration.

METHODS

Medical records of patients treated at the Lupus Clinic at University College London Hospital (UCLH) between 1979 and 2020 were retrospectively reviewed. Data about CVE, traditional cardiovascular risk factors, demographic and disease features, and treatment history were collected. Only patients with complete available information were included in the study. Regression analyses were performed to identify factors associated with CVE.

RESULTS

Four hundred and nineteen patients were included in the study. Maximum follow-up length was 40 years. Seventy-one (17%) patients had at least one CVE. Multivariable analysis showed that only antiphospholipid antibody positivity (p-value<0.001) was associated with CVE. When analysing different types of CVE, antiphospholipid antibodies were specifically associated with both venous thromboembolic events (p-value<0.001) and cerebrovascular events (p-value=0.007). Dedicated subanalyses revealed that cumulative glucocorticoid dose (p-value=0.010) and a diagnosis of SLE before 2000 (p-value<0.001) were significantly associated with CVE.

CONCLUSIONS

Cardiovascular disease is highly prevalent among patients with SLE and is associated with antiphospholipid antibodies, glucocorticoid therapy, and diagnosis before 2000.

Cardiovascular events and risk in patients with systemic lupus erythematosus: Systematic literature review and meta-analysis

BACKGROUND

Systemic lupus erythematosus (SLE) is an autoimmune disease that typically affects women aged 16-55 years. Cardiovascular disease (CVD) is a well-recognized complication of SLE. This systematic literature review and meta-analysis evaluated the relative risk (RR; compared with non-SLE controls), absolute risk (AR; as incidence proportion, n/N), and incidence rate (IR) of CVD events (including stroke, myocardial infarction [MI], and CVD [composite or undefined]) in adult patients with SLE. The RR of CV risk factors (including hypertension, diabetes, and metabolic syndrome [MetS]) was also examined.

METHODS

PubMed and Embase were searched on September 10, 2020. Observational studies published between January 2010 and September 2020 that reported RR, AR, and/or IR of CVD events, or RR of CV risk factors, were eligible. Pooled risk estimates were calculated using a random-effects model.

RESULTS

Forty-six studies (16 cross-sectional, 15 retrospective cohort, 14 prospective cohort, and 1 case-control) were included in meta-analyses. Most studies were considered high quality (Critical Appraisal Skills Programme checklists). Compared with adults without SLE, patients with SLE had statistically significantly higher RRs (95% CIs) of stroke (2.51 [2.03-3.10]; 12 studies), MI (2.92 [2.45-3.48]; 11 studies), CVD (2.24 [1.94-2.59]; 8 studies), and hypertension (2.70 [1.48-4.92]; 7 studies). RRs of diabetes (1.24 [0.78-1.96]; 3 studies) and MetS (1.49 [0.95-2.33]; 7 studies) were elevated but not significant. RRs of stroke and MI were generally higher in younger versus older patients with SLE. In patients with SLE, the pooled estimate of AR (95% CI) was 0.03 (0.02-0.05), 0.01 (0.00-0.02), and 0.06 (0.03-0.10) for stroke (7 studies), MI (6 studies), and CVD (8 studies), respectively. The pooled estimate of IR per 1000 person-years (95% CI) was 4.72 (3.35-6.32), 2.81 (1.61-4.32), and 11.21 (8.48-14.32) for stroke (10 studies), MI (6 studies), and CVD (8 studies), respectively. Although heterogeneity (based on I² value) was high in most analyses, sensitivity analyses confirmed the robustness of the pooled estimates.

CONCLUSIONS

This meta-analysis found an increased risk of stroke, MI, CVD, and hypertension in patients with SLE compared with the general population, despite substantial heterogeneity across the included studies.

Management and long-term outcomes of patients with chronic inflammatory diseases experiencing ST-segment elevation myocardial infarction: The SCALIM registry

BACKGROUND

Patients with chronic inflammatory diseases (CIDs) are at increased risk of cardiovascular events. However, the prognostic impact of CID after an acute coronary event has been poorly studied.

AIMS

To examine the effect of history of CID on long-term outcome in patients with ST-segment elevation myocardial infarction (STEMI).

METHODS

We analysed data from SCALIM, a regional registry that prospectively enrolled patients with STEMI between June 2011 and May 2019. The presence of CID (including inflammatory bowel diseases, rheumatic conditions, inflammatory skin diseases, multiple sclerosis, vasculitis and autoimmune diseases) was identified. The primary outcome was all-cause death. Secondary outcomes were cardiovascular death, myocardial infarction, ischaemic stroke, peripheral vascular events and rehospitalization for cardiovascular conditions.

RESULTS

Data from 1941 patients with STEMI (mean age 64.8±14.1 years, 75.1% men) were analyzed. The prevalence of any CID was 4.6% (n=89). After a mean follow-up of 3.4±2.6 years, the overall death rate was 16.2%, with similar 5-year survival between patients with and without CID (74.2% vs. 81.9%, respectively; P=0.121), with no significant mortality excess (hazard ratio: 1.15, 95% confidence interval: 0.73-1.82; P=0.55). However, among CID patients, 35 (39.3%) were on corticosteroid therapy and showed decreased 5-year survival (52.8% vs. 89.5% without corticosteroids; P=0.001). We found no increased rate of secondary endpoints, except for peripheral vascular events (5-year survival free of peripheral events: 93.3% vs. 98.6% in those without CID; P=0.005).

CONCLUSIONS

Approximately 1 in 20 patients with STEMI has CID. We found no effect of CID on long-term survival. However, patients on corticosteroid therapy appeared to have higher rates of death during follow-up. Whether this finding is related to the use of corticosteroids or to the more progressive nature of their condition warrants further investigation.

Immune mechanisms associated with cardiovascular disease in systemic lupus erythematosus: A path to potential biomarkers

Systemic lupus erythematosus (SLE) patients display an increased risk of cardiovascular disease (CVD). With the improved clinical management of other classical severe manifestation of the disease, CVD is becoming one of the most relevant complications of SLE, and it is an important factor causing morbidity and mortality. Several immune constituents have been shown to be involved in the pathogenesis of atherosclerosis and endothelial damage in SLE patients, including specific circulating cell populations, autoantibodies, and inflammatory mediators. In this review, we summarize the presentation of CVD in SLE and the role of the autoimmune responses present in SLE patients in the induction of atherogenesis, endothelial impairment and cardiac disease. Additionally, we discuss the utility of these immune mediators as early CVD biomarkers and targets for clinical intervention in SLE patients.

CRP Serum Levels Are Associated with High Cardiometabolic Risk and Clinical Disease Activity in Systemic Lupus Erythematosus Patients

Systemic lupus erythematosus (SLE) patients have a higher frequency of cardiovascular risk factors such as high C-reactive protein (CRP) levels than the general population. CRP is considered a cardiovascular disease marker that could be related to SLE clinical disease activity. This study aimed to assess the association between CRP with cardiometabolic risk and clinical disease activity in SLE patients. A comparative cross-sectional study was conducted in 176 female SLE patients and 175 control subjects (CS) with median ages of 38 and 33 years, respectively; SLE patients were classified by the 1997 SLE-ACR criteria, and the clinical disease activity by the Mexican-SLEDAI (Mex-SLEDAI). CRP and lipid profile (triglycerides, cholesterol, HDL-C, and LDL-C) were quantified by turbidimetry and colorimetric-enzymatic assays, respectively. SLE patients had higher CRP levels than CS (SLE: 5 mg/L vs. CS = 1.1 mg/L; p < 0.001). In SLE patients, CRP levels ≥ 3 mg/L were associated with a higher risk of cardiometabolic risk status assessed by LAP index (OR = 3.01; IC: 1.04−8.7; p = 0.04), triglycerides/HDL-C index (OR = 5.2; IC: 2.1−12.8; p < 0.001), Kannel index (OR = 3.1; IC: 1.1−8.1; p = 0.03), Castelli index (OR = 6.6; IC: 2.5−17.8; p < 0.001), and high clinical disease activity (OR = 2.5: IC: 1.03−6.2; p = 0.04; and β coefficient = 5.8; IC: 2.5−9.4; R2 = 0.15; p = 0.001). In conclusion, high CRP levels were associated with high cardiometabolic risk and clinical disease activity in SLE patients.

Risk of Acute Myocardial Infarction in Patients with Gastroenteritis: A Nationwide Case-Control Study

Gastroenteritis promotes the development of systemic inflammation and a hypercoagulable state. There are limited data regarding the association between gastroenteritis and acute myocardial infarction (AMI). We aimed to evaluate the risk of AMI after an episode of gastroenteritis. In this nested case-control study, we selected patients who were hospitalized for AMI (N = 103,584) as a case group during 2010-2017 and performed propensity score matching (case-control ratio 1:1) to select eligible controls from insurance research data in Taiwan. We applied multivariable logistic regressions to calculate adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for the risk of AMI associated with recent gastroenteritis within 14 days before AMI. We also compared the outcomes after AMI in patients with or without gastroenteritis. A total of 1381 patients (1.3%) with AMI had a prior episode of gastroenteritis compared to 829 (0.8%) among the controls. Gastroenteritis was significantly associated with a subsequent risk of AMI (adjusted OR: 1.68, 95% CI: 1.54-1.83), which was augmented in hospitalizations for gastroenteritis (adjusted OR: 2.50, 95% CI: 1.20-5.21). The outcomes after AMI were worse in patients with gastroenteritis than in those without gastroenteritis, including increased 30-day in-hospital mortality (adjusted OR: 1.28, 95% CI: 1.08-1.52), medical expenditure, and length of hospital stay. Gastroenteritis may act as a trigger for AMI and correlates with worse post-AMI outcomes. Strategies of aggressive hydration and/or increased antithrombotic therapies for this susceptible population should be further developed.

Clinical Outcomes of Acute Myocardial Infarction Hospitalizations with Systemic Lupus Erythematosus: An Analysis of Nationwide Readmissions Database

BACKGROUND

Hospital readmissions post-acute myocardial infarctions (AMIs) are associated with adverse cardiovascular outcomes and also incur huge healthcare costs. Patients with systemic lupus erythematosus (SLE) are at an increased risk of AMI likely due to multi-factorial mechanisms including higher levels of inflammation and accelerated atherosclerosis. We investigated if patients with SLE are at higher risk of hospital readmissions post-AMI compared to the patients without SLE. Furthermore, we sought to assess if inpatient outcomes of AMI in SLE patients are different than AMI without SLE.

METHODS

We conducted a retrospective analysis of adult hospital discharges with the principal diagnosis of AMI using the Nationwide Readmissions Database in 2018. We used the International Classification of Diseases, Tenth Revision, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) to identify comorbid conditions. The primary outcome was all-cause 30-day readmission. Secondary outcomes were cardiac procedures at index hospitalization (percutaneous coronary intervention [PCI] and coronary artery bypass grafting [CABG]), and adverse events at index hospitalization, including inpatient mortality, cardiac arrest, cardiogenic shock, cardiac assist device, coronary artery dissection, acute kidney injury, gastrointestinal bleeding, stroke, post-procedural hemorrhage, sepsis, and hospital costs. Complex samples multivariable logistic regression models were used to determine the association of SLE with outcomes.

RESULTS

The patients with AMI and SLE had a higher 30-day readmission rate (15.5% vs 12.5%, aOR=1.33, CI 1.12 - 1.57, p=0.001), and inpatient mortality (aOR=1.40 CI 1.1 - 1.79, p=0.006) compared to the AMI without SLE cohort. The rates of acute kidney injury (aOR=1.41 CI 1.21 - 1.64, p<0.0001) and sepsis (aOR= 1.61 CI 1.16 - 2.23, p=0.004) were higher among AMI with SLE group as compared to AMI without SLE group. Within the AMI with SLE cohort, the independent predictors of readmission were diabetes mellitus (aOR=1.38 CI 0.99 - 1.91, p=0.054), peripheral vascular disease (aOR=2.10 CI 1.22 - 3.62, p=0.007), anemia (aOR=1.50 CI 1.07 - 2.11, p=0.019), end-stage renal disease (aOR=1.91 CI 1.10 - 3.31, p=0.021), and congestive heart failure (aOR=1.55 CI 1.12 - 2.16, p=0.009). The length of stay in days during index hospitalization (5.10 vs 4.67) was similar in both cohorts. In the multivariable-adjusted regression model, no statistically significant differences were noted between the AMI with SLE and AMI without SLE cohorts for most inpatient adverse events during the index hospitalization CONCLUSION: Patients with AMI and SLE had higher inpatient mortality during the index hospitalization and higher 30-day hospital readmissions compared to AMI patients without SLE. There were no significant differences in most of the other major inpatient outcomes between the two cohorts.

American College of Rheumatology White Paper on Antimalarial Cardiac Toxicity

Hydroxychloroquine (HCQ) and chloroquine (CQ) are well-established medications used in treating systemic lupus erythematosus and rheumatoid arthritis, as well as skin conditions such as cutaneous lupus erythematosus. In rare cases, arrhythmias and conduction system abnormalities, as well as cardiomyopathy, have been reported in association with HCQ/CQ use. Recently, however, the corrected QT interval (QTc)-prolonging potential of these medications, and risk of torsade de pointes (TdP) in particular, have been highlighted in the setting of their experimental use for COVID-19 infection. This report was undertaken to summarize the current understanding of HCQ/CQ cardiac toxicity, describe QTc prolongation and TdP risks, and discuss areas of priority for future research. A working group of experts across rheumatology, cardiology, and dermatology performed a nonsystematic literature review and offered a consensus-based expert opinion. Current data clearly indicate that HCQ and CQ are invaluable medications in the management of rheumatic and dermatologic diseases, but they are associated with QTc prolongation by directly affecting cardiac repolarization. Prescribing clinicians should be cognizant of this small effect, especially in patients taking additional medications that prolong the QTc interval. Long-term use of HCQ/CQ may lead to a cardiomyopathy associated with arrhythmias and heart failure. Risk and benefit assessment should be considered prior to initiation of any medication, and both initial and ongoing risk-benefit assessments are important with regard to prescription of HCQ/CQ. While cardiac toxicity related to HCQ/CQ treatment of rheumatic diseases is rarely reported, it can be fatal. Awareness of the potential adverse cardiac effects of HCQ and CQ can increase the safe use of these medications. There is a clear need for additional research to allow better understanding of the cardiovascular risk and safety profile of these therapies used in the management of rheumatic and cutaneous diseases.

Integrative Therapy Combining Chinese Herbal Medicines With Conventional Treatment Reduces the Risk of Cardiovascular Disease Among Patients With Systemic Lupus Erythematosus: A Retrospective Population-Based Cohort Study

Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease that involves multiple systems and organs. Advanced conventional treatment does not appear to markedly reduce the risk of cardiovascular disease (CVD) among patients with SLE. Chinese medicine is a complementary and alternative medicine system, and some SLE patients in Taiwan also use Chinese herbal medicines (CHMs). Thus, we aimed to investigate whether integrative therapy combining CHMs with conventional therapy reduces the risk of CVD among patients with SLE. We performed a 12-years population-based retrospective cohort study using the “Systemic Lupus Erythematosus Health Database” of the National Health Insurance Research Database (NHIRD) in Taiwan. Patients newly diagnosed with SLE between 2004 and 2013 were divided into CHM and non-CHM groups and followed up until the end of 2015. We applied 1:1 individual matching by age, gender, and year of being newly diagnosed with SLE; accordingly, 2,751 patients were included in both CHM and non-CHM groups after matching. We applied the Cox proportional hazard regression model to determine the risk of CVD in relation to CHM use. During the follow-up period, 407 patients in the CHM group and 469 patients in the non-CHM group developed CVD, with incidence rates of 337 and 422 per 10,000 person-years, respectively. The Cox proportional hazards model demonstrated a significantly decreased risk of CVD among SLE patients using CHMs (adjusted HR: 0.83; 95% CI 0.73–0.95; p = 0.008). Further analyses of different types of CVDs also showed a significantly decreased risk of ischemic stroke in the CHM group (adjusted HR: 0.74; 95% CI 0.57–0.97; p = 0.032). Among the frequently used single herbs and polyherbal formulas, Shu-Jing-Huo-Xue-Tang was associated with a significantly decreased risk of CVD (adjusted HR: 0.76; 95% CI 0.58–0.99; p = 0.041). In conclusion, CHM use reduced the risk of CVD among patients with SLE in Taiwan. Further randomized studies may be needed to determine the definite causal relationship between CHM use and its protective effects against CVD among patients with SLE.

Cardiovascular disease in systemic lupus erythematosus

There is a well-known increased risk for cardiovascular disease that contributes to morbidity and mortality in systemic lupus erythematosus (SLE). Major adverse cardiovascular events and subclinical atherosclerosis are both increased in this patient population. While traditional cardiac risk factors do contribute to the increased risk that is seen, lupus disease-related factors, medications, and genetic factors also impact the overall risk. SLE-specific inflammation, including oxidized lipids, cytokines, and altered immune cell subtypes all are likely to play a role in the pathogenesis of atherosclerotic plaques. Research is ongoing to identify biomarkers that can help clinicians to predict which SLE patients are at the greatest risk for cardiovascular disease (CVD). While SLE-specific treatment regimens for the prevention of cardiovascular events have not been identified, current strategies include minimization of traditional cardiac risk factors and lowering of overall lupus disease activity.

Long-term prognosis of vascular access in hemodialysis patients with systemic lupus erythematosus: a retrospective cohort study

Patients with systemic lupus erythematosus (SLE) have a higher risk of vascular complications. This retrospective cohort study aimed to analyze the differences in the risk of arteriovenous fistula or graft (AVF/AVG) dysfunction in hemodialysis patients with and without SLE from Taiwan's National Health Insurance Database over a 10-year period. AVF/AVG dysfunction is defined as the occurrence of the first episode of intervention after vascular access creation. A total of 1366 HD patients with SLE had higher incidence rates of AVF/AVG dysfunction than 4098 non-SLE HD patients in the following 4 periods: (1) after 1 year (incidence rates = 15.21% and 13.01%, respectively; subdistribution hazard ratio (SHR) = 1.16; P = 0.007), (2) 1st-to-10th-year period (15.36% and 13.25%; SHR = 1.16; P = 0.007), (3) 5th-to-10th-year period (11.91% and 8.1%; SHR = 1.42; P = 0.003), and (4) overall period (23.53% and 21.66%; SHR = 1.09; P = 0.027). In conclusion, there were significantly higher incidence rates of AVF/AVG dysfunction in SLE patients during the long-term follow-up period. Vascular access function should be monitored regularly by clinical examinations, especially after 1 year and during 5 to 10 years, to improve AVF/AVG patency and dialysis adequacy in SLE patients undergoing maintenance hemodialysis.

Myocardial Infarction in Systemic Lupus Erythematosus: Incidence and Coronary Angiography Findings

An association between acute myocardial infarction (AMI) and systemic lupus erythematosus (SLE) has been suggested. The cause of AMI is presumed to be atherothrombosis. In the present study, the primary objective was to assess incident AMI cases and the secondary objective was to estimate the proportion of myocardial infarction with nonobstructive coronary arteries (MINOCA) in patients with SLE. All Swedish patients with SLE without AMI before 1996 (n = 4192) were followed for 20 years in the national patient registry. For each SLE patient, 10 age- and sex-matched controls without SLE and AMI before 1996 (n = 41 892) were identified. Data from patients and controls with AMI after 1996 were linked with the Swedish coronary angiography and angioplasty register; 549 (13%) and 3352 (8%) first AMIs occurred in patients with SLE and controls, respectively. The incidence of AMI was 9.6 (95% CI: 8.9-10.5) and 4.9 (95% CI: 4.8-5.1) events/1000 person-years in patients with SLE and controls, respectively. The proportion of MINOCA was 10.8% in patients with SLE and 13.8% in controls (P = .261), respectively. In conclusion, the incidence of AMI is increased in a European population of patients with SLE but there is no indication that the proportion of MINOCA is increased in these patients.

Lipid-lowering therapy: Guidelines to precision medicine

Dyslipidemia is correlated with a series of health problems, such as obesity, insulin resistance, and the development of cardiovascular disease (CVD). Currently, accumulating evidence sheds light on the fact that β-hydroxy β-methylglutaryl-CoA reductase inhibitors, named statins, could lower circulating lipid-density lipoprotein cholesterol (LDL-C) and represent a revolution for the prevention of metabolic disorder diseases. In addition, statins remain the cornerstone of LDL-C-lowering treatments, together with ezetimibe and bile acid sequestrants, which are used either in combination with statins or as monotherapies in the case of statin intolerance or side effects. On the other hand, other medicines that reduce circulating LDL-C have also been researched, including inhibitors of protein convertase subtilisin/kexin type 9 (PCSK9). More recently, PCSK9 inhibitors have been approved for the secondary prevention of CVD and for the atherogenic dyslipidemia therapy. Here, we summarize the latest guidelines for the management of dyslipidemia and its relation to CVD, focusing on LDL-C-lowering medicines that are either available in daily clinical practice or under investigation. In addition, we also discuss the "who, when, and how" with respect to treating patients with dyslipidemia according to LDL-C reduction as an individualized clinical precision medicine.

Systemic lupus erythematosus; stroke and myocardial infarction risk: a systematic review and meta-analysis

OBJECTIVE

To evaluate the risk of stroke and myocardial infarction (MI) in adult patients with systemic lupus erythematosus (SLE) through a systematic review and meta-analysis.

METHODS

We searched MEDLINE and EMBASE from inception to May 2020 to identify observational studies (cohort and cross-sectional) that evaluated risk of stroke and MI in adult patients with SLE compared with the general population or healthy controls. Studies were included if they reported effect-size estimates that could be used for calculating pooled-effect estimates. Random-effects models were used to calculate pooled risk ratios (RRs) and 95% CIs for stroke and MI. Heterogeneity quantified by the I² test and sensitivity analyses assessed bias.

RESULTS

In total, 26 studies were included in this meta-analysis: 14, 5 and 7 studies on stroke, MI and both stroke and MI, respectively. The pooled RR for ischaemic stroke was 2.18 (95% CI 1.78 to 2.67; I² 75%), intracerebral haemorrhage 1.84 (95% CI 1.16 to 2.90; I² 67%), subarachnoid haemorrhage 1.95 (95% CI 0.69 to 5.52; I² 94%), composite stroke 2.13 (95% CI 1.73 to 2.61; I² 88%) and MI 2.99 (95% CI 2.34 to 3.82; I² 85%). There was no evidence for publication bias, and sensitivity analyses confirmed the robustness of the results.

CONCLUSIONS

Overall, patients with SLE were identified to have a twofold to threefold higher risk of stroke and MI. Future research on the interaction between known SLE-specific modifiable risk factors and risk of stroke and MI to support development of prevention and treatment strategies are needed.

Outcomes of acute cardiovascular events in rheumatoid arthritis and systemic lupus erythematosus: a population-based study

OBJECTIVES

Patients with RA and SLE have an excess cardiovascular risk. We aimed to evaluate outcomes of acute cardiovascular events in these patients.

METHODS

Using a nationwide database of Taiwan, we identified adult patients who experienced first-time acute myocardial infarction (n = 191 008), intracranial haemorrhage (n = 169 923) and ischaemic stroke (n = 486 890) over a 13-year period. Odds ratios (ORs) of in-hospital mortality and hazard ratios (HRs) of overall mortality and adverse outcomes during long-term follow-up in relation to RA and SLE were estimated with adjustment for potential confounders.

RESULTS

In each cohort, 748, 410 and 1419 patients had established RA; 256, 292 and 622 patients had SLE. Among acute myocardial infarction patients, RA and SLE were associated with in-hospital mortality (RA: OR 1.61, 95% CI 1.33, 1.95; SLE: OR 2.31, 95% CI 1.62, 3.28) and overall mortality. Additionally, RA (HR 1.28, 95% CI 1.18, 1.38) and SLE (HR 1.46, 95% CI 1.27, 1.69) increased the risk of major adverse cardiac events. After intracranial haemorrhage, patients with RA and SLE had higher risks of in-hospital mortality (RA: OR 1.61, 95% CI 1.26, 2.06; SLE: OR 3.00, 95% CI 2.33, 3.86) and overall mortality. After ischaemic stroke, RA and SLE increased in-hospital mortality (RA: OR 1.45, 95% CI 1.15, 1.83; SLE: OR 2.18, 95% CI 1.57, 3.02), overall mortality and recurrent cerebrovascular events (RA: HR 1.10, 95% CI 1.002, 1.21; SLE: HR 1.31, 95% CI 1.14, 1.51), among which ischaemic stroke (HR 1.39, 95% CI 1.19, 1.62) was more likely to recur in SLE patients.

CONCLUSION

Both RA and SLE are consistently associated with adverse outcomes following acute cardiovascular events, highlighting the necessity of integrated care for affected patients.

Link Between Synovial and Myocardial Inflammation: Conceptual Framework to Explain the Pathogenesis of Heart Failure with Preserved Ejection Fraction in Patients with Systemic Rheumatic Diseases

Patients with a broad range of systemic rheumatic diseases are at increased risk of heart failure (HF), an event that is not related to traditional cardiovascular risk factors or underlying ischaemic heart disease. The magnitude of risk is linked to the severity of arthritic activity, and HF is typically accompanied by a preserved ejection fraction. Subclinical evidence for myocardial fibrosis, microcirculatory dysfunction and elevated cardiac filling pressures is present in a large proportion of patients with rheumatic diseases, particularly those with meaningful systemic inflammation. Drugs that act to attenuate pro-inflammatory pathways (methotrexate and antagonists of tumour necrosis factor and interleukin-1) may ameliorate myocardial inflammation and cardiac structural abnormalities and reduce the risk of HF events.

Postimplantation Syndrome Is Not Associated with Myocardial Injury after Noncardiac Surgery after Endovascular Aneurysm Repair

BACKGROUND

Postimplantation syndrome (PIS) is the clinical and biochemical expression of an inflammatory response following endovascular aneurysm repair (EVAR), with a reported incidence ranging from 2% to 100%. Although generally benign, some studies report an association between PIS and postoperative major adverse cardiovascular events (MACEs). Nonetheless, the role of PIS in postoperative myocardial injury after noncardiac surgery (MINS) is unknown. This work aims to evaluate the relationship between PIS and MINS in a subset of EVAR patients, as well as assess the impact of PIS in all-cause mortality.

METHODS

All patients undergoing elective standard EVAR between January 2008 and June 2017, and with at least one measurement of contemporary (cTnI) or high sensitivity troponin I (hSTnI) in the first 48h after surgery, were retrospectively analyzed. PIS was defined as the presence of fever and leukocytosis in the postoperative period in the absence of infectious complications. MINS was defined as the value exceeding the 99th percentile of a normal reference population with a coefficient of variation <10%, which was >0.032 ng/mL for cTnI and 0.0114 (female) and 0.027 ng/mL (male) for hSTnI. Patients' demographics, comorbidities, medication, access, and anesthesia were also evaluated.

RESULTS

One hundred thirty-three consecutive patients were included (95.5% male; mean age 75.66 ± 7.13 years). Mean follow-up was 46.35 months. Survival rate was 86.5%, 80.5%, and 57.6% at 1, 3, and 5 years of follow-up, with 2 fatalities at 30 days of follow-up. The prevalence of PIS was 11.4%. MACE occurred in 2.3% of the patients, while MINS was reported in 16.5% of the patients. No association was found between PIS and patients' gender, comorbidities, type of anesthesia, or transfusional support. The type of graft used significantly affected the prevalence of PIS, with all cases reported when polyester grafts were used (P = 0.031). MACE occurred in 2.3% of the patients, while MINS was reported in 16.5% of the patients. PIS was found to be significantly associated with postoperative MACE (P = 0.001), but not MINS. Survival analysis revealed no differences between patients with or without PIS regarding 30-day mortality as well as long-term all-cause mortality. American Society of Anesthesiologists score (hazard ratio [HR] 2.157, 95% confidence interval [CI] 1.07-4.33, P = 0.031) and heart failure (HR 2.284, 95% CI 1.25-4.18, P = 0.008) were found to be independently associated with increased long-term all-cause mortality in this cohort of patients.

CONCLUSIONS

PIS is a common complication after EVAR, occurring in 11.4% of the patients from this cohort. Graft type seems to significantly affect the risk of PIS, since all reported cases occurred when polyester grafts were used. PIS did not influence 30-day or long-term survival and was found to be significantly associated with postoperative MACE but not MINS, suggesting the involvement of different pathophysiological mechanisms.

Vaccination Strategies and Immune Modulation of Atherosclerosis

Adaptive as well as innate immune responses contribute to the development of atherosclerosis. Studies performed in experimental animals have revealed that some of these immune responses are protective while others contribute to the progression of disease. These observations suggest that it may be possible to develop novel therapies for cardiovascular disease by selectively modulating such atheroprotective and proatherogenic immunity. Recent advances in cancer treatment using immune check inhibitors and CAR (chimeric antigen receptor) T-cell therapy serve as excellent examples of the possibilities of targeting the immune system to combat disease. LDL (low-density lipoprotein) that has accumulated in the artery wall is a key autoantigen in atherosclerosis, and activation of antigen-specific T helper 1–type T cells is thought to fuel plaque inflammation. Studies aiming to prove this concept by immunizing experimental animals with oxidized LDL particles unexpectedly resulted in activation of atheroprotective immunity involving regulatory T cells. This prompted several research groups to try to develop vaccines against atherosclerosis. In this review, we will discuss the experimental and clinical data supporting the possibility of developing immune-based therapies for lowering cardiovascular risk. We will also summarize ongoing clinical studies and discuss the challenges associated with developing an effective and safe atherosclerosis vaccine.

Systemic lupus erythematosus is associated with poor outcome after acute myocardial infarction

BACKGROUND

Systemic lupus erythematosus (SLE) is associated with a higher risk of cardiovascular disease. However, it is not clear whether or not SLE is associated with poor outcomes after acute myocardial infarction (AMI).

METHODS AND RESULTS

Using the Taiwan National Health Insurance Database, we identified the SLE group as patients with AMI who have a concurrent discharge diagnosis of SLE. We also selected an age-, sex-, hospital level-, and admission calendar year-matched non-SLE group at a ratio of 1:3 from the total non-SLE group. One hundred fifty-one patients with SLE, 113,791 patients without SLE, and 453 matched patients without SLE were admitted with a diagnosis of AMI. Patients with SLE were significantly younger, predominantly female, and more likely to have chronic kidney disease than those without SLE. The in-hospital mortality rates were 12.6%, 9.0%, and 4.2% in the SLE, total non-SLE, and matched non-SLE groups, respectively. The in-hospital mortality was significantly higher in the SLE group than in the total non-SLE group (OR = 1.98; 95% CI = 1.2-3.26) and the matched non-SLE group (mortality OR = 2.20; 95% CI = 1.06-4.58). In addition, the SLE group was associated with a borderline significant risk of prolonged hospitalization when compared with the non-SLE group.

CONCLUSION

SLE is associated with a higher risk of in-hospital mortality and a borderline significantly higher risk of prolonged hospitalization after AMI.

A Meta-Analysis of Cardiovascular Events in Systemic Lupus Erythematosus

Objective: To identify accurate occurrence and risk of cardiovascular (CV) events (stroke and myocardial infarction [MI]) in patients with systemic lupus erythematosus (SLE). Methods: Systemic literature search in PubMed and additional manual search were performed to obtain interested studies until March 31, 2018. The pooled incidences and risk of stroke and MI were calculated. Results: A total of 24 studies were included in this meta-analysis. For MI, a total of 1,516 SLE patients were reported to had MI (n = 96,154) over a mean follow-up of 9.98 years: incidence 2.0% (95% CI: 1.7-2.4%), i.e. 0.20/100 pyrs; in the five studies, 360 SLE patients (n = 18,943) and 817 controls had MI (n = 111,525), revealing that the risk of MI in SLE population was 3.04 times higher than in the general population (RR = 3.04, 95% CI: 1.81-5.11). For stroke, the incidence of 17 studies during the 10.09 follow-up period using random model was 4.4% (95% CI: 3.6-5.1%), i.e. 0.44/100 pyrs; in the 7 studies, 694 SLE patients (n = 22,594) and 4,034 controls had stroke (n = 255,023), indicating that the risk of MI in SLE population was 1.95 times higher than that in the general population (RR = 1.95, 95% CI: 1.52-2.53). Conclusion: Based on the findings from previous reports, our meta-analysis showed that patients with SLE have been at higher risk of CV events.

Acute Myocardial Infarction Outcomes in Systemic Lupus Erythematosus (from the Nationwide Inpatient Sample)

One of the major causes of mortality in systemic lupus erythematosus (SLE) is acute myocardial infarction. Whether in-hospital outcomes and management of ST-segment elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI) are different in SLE patients compared with those without SLE from large, recent dataset is unclear. We queried the Nationwide Inpatient Database from 2005 to 2014 and identified STEMI and NSTEMI admissions with and without SLE. The primary outcome was in-hospital mortality. Secondary outcomes were revascularization strategy (percutaneous coronary intervention, coronary artery bypass surgery, or thrombolytics), medical therapy rates (no reperfusion), and major adverse clinical events. A propensity-matched cohort was created to compare these outcomes. Odds ratio (OR) was calculated from the propensity-matched cohort. A total of 321,048 STEMI admissions, of which 1,001 (0.31%) and 572,971 NSTEMI admissions, of which 2,134 (0.37%) were SLE, were identified. In those with STEMI, 882 SLE and non-SLE admissions were propensity-matched. In-hospital mortality (9.1% vs 11.8%, OR 0.75, p = 0.07), revascularization strategy, medical therapy rates, and major adverse events were similar. Similarly, in those with NSTEMI, 1,770 SLE and 1,775 non-SLE were matched. In-hospital mortality (4.1% vs 4.50%, OR 0.90, p = 0.51), coronary artery bypass surgery, medical therapy rates, and major adverse events were mostly similar but the rate of percutaneous coronary intervention was higher in SLE (32.9% vs 29.6%, OR 1.16, p = 0.04). For both STEMI and NSTEMI, hospital cost and length of stay were similar between SLE and non-SLE cohorts. From a large administrative database in the United States, revascularization strategies and in-hospital outcomes of acute coronary syndrome were mostly similar between SLE and non-SLE.

Cardiovascular magnetic resonance detects silent heart disease missed by echocardiography in systemic lupus erythematosus

Background

Accurate diagnosis of cardiovascular involvement in systemic lupus erythematosus (SLE) remains challenging, due to limitations of echocardiography. We hypothesized that cardiovascular magnetic resonance can detect cardiac lesions missed by echocardiography in SLE patients with atypical symptoms.

Aim

To use cardiovascular magnetic resonance in SLE patients with atypical symptoms and investigate the possibility of silent heart disease, missed by echocardiography.

Patients/methods

From 2005 to 2015, 80 SLE patients with atypical cardiac symptoms/signs (fatigue, mild shortness of breath, early repolarization and sinus tachycardia) aged 37 ± 6 years (72 women/8 men), with normal echocardiography, were evaluated using a 1.5 T system. Left and right ventricular ejection fractions, T2 ratio (oedema imaging) and late gadolinium enhancement (fibrosis imaging) were assessed. Acute and chronic lesions were defined as late gadolinium enhancement-positive plus T2>2 and T2<2, respectively. Lesions were characterized according to late gadolinium enhancement patterns as: diffuse subendocardial, subepicardial and subendocardial/transmural, due to vasculitis, myocarditis and myocardial infarction, respectively.

Results

Abnormal cardiovascular magnetic resonance findings were identified in 22/80 (27.5%) of SLE patients with normal echocardiography, including 4/22 with recent silent myocarditis, 5/22 with past myocarditis (subepicardial scar in inferolateral wall), 9/22 with past myocardial infarction (six inferior and three anterior subendocardial infarction) and 4/22 with diffuse subendocardial fibrosis due to vasculitis. No correlation between cardiovascular magnetic resonance findings and inflammatory indices was identified.

Conclusions

Cardiovascular magnetic resonance in SLE patients with atypical cardiac symptoms/signs and normal echocardiography can assess occult cardiac lesions including myocarditis, myocardial infarction and vasculitis that may influence both rheumatic and cardiac treatment.

Differential gene expression profiles in peripheral blood in Northeast Chinese Han people with acute myocardial infarction

This study aimed to use gene chips to investigate differential gene expression profiles in the occurrence and development of acute myocardial infarction (AMI). The study included 12 AMI patients and 12 healthy individuals. Total mRNA of peripheral bloodwas extracted and reversed-transcribed to cDNA for microarray analysis. After establishing two pools with three subjects each (3 AMI patients and 3 healthy individuals), the remaining samples were used for RT-qPCR to confirm the microarray data. From the microarray results, seven genes were randomly selected for RT-qPCR. RT-qPCR results were analyzed by the 2^-ΔΔCt method. Microarray analysis showed that 228 genes were up- regulated and 271 were down-regulated (p ≤ 0.05, |logFC| > 1). Gene ontology showed that these genes belong to 128 cellular components, 521 biological processes, and 151 molecular functions. KEGG pathway analysis showed that these genes are involved in 107 gene pathways. RT-qPCR results for the seven genes showed expression levels consistent with those obtained by microarray. Thus, microarray data could be used to select the pathogenic genes for AMI. Investigating the abnormal expression of these differentially expressed genes might suggest efficient strategies for the prevention, diagnosis, and treatment of AMI.

Incidence and risk of acute coronary syndrome in patients with acute pancreatitis: A nationwide cohort study

BACKGROUND

Studies on the relationship between acute pancreatitis (AP) and acute coronary syndrome (ACS) are scant. We conducted a nationwide cohort study to investigate the incidence and risk of ACS in patients with AP.

METHODS

We enrolled patients newly diagnosed with AP between 2000 and 2010 from the Taiwan National Health Insurance Research Database and randomly selected a control cohort without a history of AP after frequency-matching for age, sex, and index year at a ratio of 4:1 for each patient with AP. The follow-up period was from the index date of new AP diagnosis to the diagnosis of ACS, censoring, or the end of 2011.

RESULTS

We assessed 87 068 patients in the AP cohort and 348 272 participants in the control cohort for 508 991 and 2 301 317 person-years, respectively. The AP cohort exhibited a higher overall incidence of ACS than the control cohort (5.44 vs 3.03 per 1000 person-y). After adjustment for sex, age, and comorbidities, the AP cohort exhibited a 1.24-fold higher adjusted hazard ratio (aHR) of ACS (95% confidence interval = 1.19-1.30) than did the control cohort. When stratified by age, the patients with AP aged ≤39 years presented a 2.37-fold higher aHR of ACS than did their corresponding controls (95% CI = 1.88-2.99). Approximate one third of ACS developed within 1 month of AP occurrence.

CONCLUSIONS

This nationwide cohort study indicated that patients with AP are at an increased risk of ACS compared with those without AP.

Cardiovascular disease in systemic lupus erythematosus: A comprehensive update

Heightened rates of both cardiovascular (CV) events and subclinical atherosclerosis, documented by imaging and vascular function techniques are well established in systemic lupus erythematosus (SLE). While traditional CV factors such as smoking, dyslipidemia, diabetes mellitus (DM), hypertension, central obesity and hyperhomocysteinemia have been reported to be prevalent in lupus patients, they do not fully explain the high rates of ischemic events so far reported, implying that other factors inherent to disease itself could account for the enhanced risk, including disease duration, activity and chronicity, psychosocial factors, medications, genetic variants and altered immunological mechanisms. Though the exact pathogenesis of atherosclerosis in the setting of lupus remains ill defined, an imbalance between endothelial damage and atheroprotection seems to be a central event. Insults leading to endothelial damage in the setting of lupus include oxidized low density lipoprotein (oxLDL), autoantibodies against endothelial cells and phospholipids, type I interferons (IFN) and neutrophil extracellular traps (NETs) directly or through activation of type I IFN pathway. Increased oxidative stress, reduced levels of the normally antioxidant high density lipoprotein (HDL), increased levels of proinflammatory HDL (piHDL) and reduced paraoxonase activity have been related to increased oxLDL levels. On the other hand, impaired atheroprotective mechanisms in lupus include decreased capacity of endothelial repair-partly mediated by type I IFN- and dampened production of atheroprotective autoantibodies. In the present review, traditional and disease related risk factors for CV disease (CVD) in the setting of chronic autoimmune disorders with special focus on SLE will be discussed.

Effect of Systemic Lupus Erythematosus on the Risk of Incident Respiratory Failure: A National Cohort Study

Purpose

We conducted a nationwide cohort study to investigate the relationship between systemic lupus erythematosus (SLE) and the risk of incident respiratory failure.

Methods

From the National Health Insurance Research Database, we identified 11 533 patients newly diagnosed with SLE and 46 132 controls without SLE who were randomly selected through frequency-matching according to age, sex, and index year. Both cohorts were followed until the end of 2011 to measure the incidence of incident respiratory failure, which was compared between the 2 cohorts through a Cox proportional hazards regression analysis.

Results

The adjusted hazard ratio (aHR) of incident respiratory failure was 5.80 (95% confidence interval [CI] = 5.15–6.52) for the SLE cohort after we adjusted for sex, age, and comorbidities. Both men (aHR = 3.44, 95% CI = 2.67–4.43) and women (aHR = 6.79, 95% CI = 5.93–7.77) had a significantly higher rate of incident respiratory failure in the SLE cohort than in the non-SLE cohort. Both men and women aged <35 years (aHR = 31.2, 95% CI = 21.6–45.2), 35–65 years; (aHR = 6.19, 95% CI = 5.09–7.54) and ≥65 years (aHR = 2.35, 95% CI = 1.92–2.87) had a higher risk of incident respiratory failure in the SLE cohort. Moreover, the risk of incident respiratory failure was higher in the SLE cohort than the non-SLE cohort, for subjects with (aHR = 2.65, 95% CI = 2.22–3.15) or without (aHR = 9.08, 95% CI = 7.72–10.7) pre-existing comorbidities. In the SLE cohort, subjects with >24 outpatient visits and hospitalizations per year had a higher incident respiratory failure risk (aHR = 21.7, 95% CI = 18.0–26.1) compared with the non-SLE cohort.

Conclusion

Patients with SLE are associated with an increased risk of incident respiratory failure, regardless of their age, sex, and pre-existing comorbidities; especially medical services with higher frequency.

High-Risk Cardiovascular Patients: Clinical Features, Comorbidities, and Interconnecting Mechanisms

Cardiovascular disease is the leading cause of death in the Western world with an increase over the last few decades. Atherosclerosis with its different manifestations in the coronary artery tree, the cerebral, as well as peripheral arteries is the basis for cardiovascular events, such as myocardial infarction, stroke, and cardiovascular death. The pathophysiological understanding of the mechanisms that promote the development of vascular disease has changed over the last few decades, leading to the recognition that inflammation and inflammatory processes in the vessel wall are major contributors in atherogenesis. In addition, a subclinical inflammatory status, e.g., in patients with diabetes or the presence of a chronic inflammatory disease, such as rheumatoid arthritis, have been recognized as strong risk factors for cardiovascular disease. The present review will summarize the different inflammatory processes in the vessel wall leading to atherosclerosis and highlight the role of inflammation in diabetes and chronic inflammatory diseases for cardiovascular morbidity and mortality.

Subclinical right ventricle systolic dysfunction in childhood-onset systemic lupus erythematosus: insights from two-dimensional speckle-tracking echocardiography

Objective

The objective of this article is to evaluate right ventricle strain imaging by two-dimensional speckle-tracking (2DST) in childhood-onset systemic lupus erythematosus (c-SLE).

Methods

Thirty-five c-SLE patients with no signs or symptoms of heart failure and 33 healthy volunteers were evaluated by standard echocardiogram and 2DST. Conventional parameters included tricuspid annular plane systolic excursion (TAPSE), RV tissue-Doppler-derived Tei index and systolic pulmonary artery pressure. Global peak longitudinal systolic strain (PLSS) and strain rate (PLSSR) of RV were obtained by 2DST. Demographic/clinical features, SLEDAI-2K/SLICC/ACR-DI and treatment were also assessed.

Results

The median current age was similar in patients and controls (14.75 vs. 14.88 years, p = 0.62). RV PLSS was significantly reduced in c-SLE (−24.5 ± 5.09 vs. −27.62 ± 3.02%, p = 0.003). Similar findings were observed after excluding patients with pulmonary hypertension (−24.62 ± 4.87% vs. −27.62 ± 3.02%, p = 0.0041). RV PLSS was positively correlated with TAPSE ( r = +0.49, p = 0.0027) and negatively correlated with Tei index ( r = −0.34, p = 0.04) in c-SLE. RV PLSSR was not different comparing patients and controls (−0.65 s−1 ± 0.47 vs. −1.87 ± 0.49 s−1, p = 0.07). Further analysis of c-SLE patients revealed higher frequencies of neuropsychiatric manifestations (39% vs. 0%, p = 0.007) and antiphospholipid antibodies (55% vs. 18%, p = 0.035) in those with RV PLSS ≤ −23.7% vs >−23.7%. No differences were evidenced in demographic data, disease activity/damage or treatments ( p > 0.05).

Conclusions

The present study, using a new and more sensitive technique, revealed subclinical RV systolic dysfunction in c-SLE patients that may have future prognostic implications. The novel association of asymptomatic RV dysfunction with neuropsychiatric manifestations and antiphospholipid antibodies may suggest common physiopathological pathways.
