Coronary Heart Disease and Cardiovascular Risk Factors in Patients With Idiopathic Inflammatory Myopathies: A Systemic Review and Meta-Analysis

Objectives:It is well-established that the association between atherosclerotic cardiovascular diseases (ASCVD) and connective tissue diseases (CTDs), but the relationship between coronary heart disease (CHD) and idiopathic inflammatory myopathies (IIMs) remains controversial yet. The aim of this meta-analysis is to systematically evaluate the risk of CHD in IIMs patients. In addition, we explore differences in traditional cardiovascular risk factors between IIMs patients and controls.Methods:We searched Pubmed, EMBASE and Cochrane databases to identify relevant observational studies published in English up to August 2021. Pooled relative risk (RR) and 95% confidence interval (CI) was calculated using the generic inverse variance method for the risk of CHD. A meta-proportion analysis was conducted to assess differences in cardiovascular risk factors between two groups.Results:A total of 15 studies met inclusion criteria: seven studies focused on CHD and nine studies focused on traditional cardiovascular risk factors. The results demonstrated that IIMs patients had a higher risk of CHD (RR = 2.19, 95% CI: 1.40–3.42). Hypertension (OR = 1.44, 95% CI: 1.28–1.61), diabetes mellitus (OR = 1.67, 95% CI: 1.55–1.81) and dyslipidemia (OR = 1.48, 95% CI: 1.19–1.84) were more prevalent in IIMs patients compared with controls. However, there was a significant heterogeneity among studies assessing the risk of CHD and hypertension. Subgroup analysis demonstrated that definition of CHD, country and sample size may be potential sources of heterogeneity.Conclusions:IIMs patients were at increased risk of CHD, and traditional cardiovascular risk factors appeared more prevalent in IIMs patients. This systemic review offers the proof that early appropriate interventions could reduce cardiovascular-associated morbidity and mortality in IIMs patients.

Respective Mediating Effects of Social Position and Work Environment on the Incidence of Common Cardiovascular Risk Factors

Background Social position and work environment are highly interrelated and their respective contribution to cardiovascular risk is still debated. Methods and Results In a cohort of 20 625 French workers followed for 25 years, discrete‐time survival analysis with reciprocal mediating effects, adjusted for sex, age, and parental history of early coronary heart disease, was performed using Bayesian structural equation modeling to simultaneously investigate the extent to which social position mediates the effect of work environment and, inversely, the extent to which work environment mediates the effect of social position on the incidence of common cardiovascular risk factors. Depending on the factor, social position mediates 2% to 53% of the effect of work environment and work environment mediates 9% to 87% of the effect of social position. The mediation by work environment is larger than that by social position for the incidence of obesity, hypertension, dyslipidemia, diabetes, sleep complaints, and depression (mediation ratios 1.32–41.5, 6.67 when modeling the 6 factors together). In contrast, the mediation by social position is larger than that by work environment for the incidence of nonmoderate alcohol consumption, smoking, and leisure‐time physical inactivity (mediation ratios 0.16–0.69, 0.26 when modeling the 3 factors together). Conclusions The incidence of behavioral risk factors seems strongly dependent on social position whereas that of clinical risk factors seems closely related to work environment, suggesting that preventive strategies should be based on education and general practice for the former and on work organization and occupational medicine for the latter.

Care of the patient after valve intervention

This review aims to outline the current evidence base and guidance for care of patients post-valve intervention. Careful follow-up, optimisation of medical therapy, antithrombotics, reduction of cardiovascular risk factors and patient education can help improve patient outcomes and quality of life. Those with mechanical valves should receive lifelong anticoagulation with a vitamin K antagonist but in certain circumstances may benefit from additional antiplatelet therapy. Patients with surgical bioprosthetic valves, valve repairs and transcatheter aortic valve implantation also benefit from antithrombotic therapy. Additionally, guideline-directed medical therapy for coexistent heart failure should be optimised. Cardiovascular risk factors such as hyperlipidaemia, hypertension and diabetes should be treated in the same way as those without valve intervention. Patients should also be encouraged to exercise regularly, eat healthily and maintain a healthy weight. Currently, there is not enough evidence to support routine cardiac rehabilitation in individuals post-valve surgery or intervention but this may be considered on a case-by-case basis. Women of childbearing age should be counselled regarding future pregnancy and the optimal management of their valve disease in this context. Patients should be educated regarding meticulous oral health, be encouraged to see their dentist regularly and antibiotics should be considered for high-risk dental procedures. Evidence shows that patients post-valve intervention or surgery are best treated in a dedicated valve clinic where they can undergo clinical review and surveillance echocardiography, be provided with heart valve education and have access to the multidisciplinary valve team if needed.

Level of advanced oxidation protein products is associated with subclinical atherosclerosis

Background Oxidative stress is an important factor in the pathomechanism of atherosclerosis. Advanced oxidation protein products (AOPPs) are considered markers of oxidative stress. Thickening of the carotid intima-media layers indicates subclinical atherosclerosis and can be detected by carotid ultrasound. Objective Our aim was to examine the association between carotid intima-media thickness (CIMT) and the level of AOPPs. Methods Carotid duplex scans and measurements of AOPPs were performed on 476 participants of a cardiovascular population study. The presence of conventional cardiovascular risk factors was investigated with a questionnaire, physical examination, and laboratory tests. Results There was a positive correlation between maximum CIMT and the level of AOPPs only in the male population (r = 0.219, p = 0.033). Multivariate analysis has revealed that the association between AOPPs and mean or maximum CIMT was independent of cardiovascular risk factors (OR = 1.458, p = 0.004, and OR = 2.038, p < 0.001). Conclusions Among males, the elevated level of AOPPs as a marker of oxidative stress may signal the existence of early atherosclerotic alterations.

Association of circulating MR-proADM with all-cause and cardiovascular mortality in the general population: Results from the KORA F4 cohort study

Background and aim Despite its vasodilatory effect, adrenomedullin and its surrogate mid-regional pro-adrenomedullin (MR-proADM) have been found to be positively associated with all-cause and cardiovascular mortality. However, the underlying mechanisms thereof remain unclear and the associations were mostly shown in geriatric cohorts or in patients with chronic diseases. Therefore, we aimed to investigate the possible involvement of abdominal obesity, selected adipokines, and biomarkers of subclinical inflammation in the association of MR-proADM with mortality in a population based study cohort. Methods Prospective analysis of the KORA F4 study; median follow-up 9.1 (8.8–9.4) years. Complete data on MR-proADM and mortality was available for 1551 participants, aged 56.9±12.9 years (mean±SD). Correlation and regression analyses of MR-proADM with overall (BMI) and abdominal obesity (waist circumference), selected adipokines and biomarkers of subclinical inflammation. Cox proportional hazard models on the association of MR-proADM with all-cause and cardiovascular mortality with adjustment for cardiovascular risk factors and selected biomarkers in study subgroups (n = 603–1551). Results MR-proADM associated with all-cause (HR (95%CI): 2.37 (1.72–3.26) and 2.31 (1.67–3.20)) and cardiovascular mortality (4.28 (2.19–8.39) and 4.44 (2.25–8.76)) after adjustment for traditional cardiovascular risk factors including BMI or waist circumference, respectively. MR-proADM was further associated with four out of seven examined adipokines (leptin, retinol-binding protein-4, chemerin, and adiponectin) and with five out of eleven examined biomarkers of subclinical inflammation (high-sensitivity C-reactive protein, interleukin-6, myeloperoxidase, interleukin-22, and interleukin-1 receptor antagonist) after multivariable adjustment and correction for multiple testing. However, only IL-6 substantially attenuated the association of MR-proADM with all-cause mortality. Conclusions We found an association of MR-proADM with (abdominal) obesity, selected adipokines, and biomarkers of subclinical inflammation. However, the association of MR-proADM with mortality was independent of these parameters. Future studies should investigate the role of IL-6 and further characteristics of subclinical inflammation in the association between MR-proADM and all-cause mortality.
