Air pollutants increase the risk and mortality of myocardial infarction MI. The aim of this study was to assess the inflammatory changes in circulating immune cells and microRNAs in MIs related to short-term exposure to air pollutants. We studied patients with acute coronary syndromes and 57 controls with stable angina. For each patient, air pollution exposure in the h before admission, was collected. All patients underwent systematic circulating inflammatory cell analyses.

According to PM 2. Ambient air pollution is a major health risk factor, leading to cardiovascular and respiratory diseases. Worldwide almost 9 million deaths in were attributable to air pollution. In Europe an annual attributable mortality of people deaths per has been estimated. Chronic and acute exposure to air pollutants are both associated with an increased how does preimplantation genetic diagnosis work of myocardial infarction MI 23.

Furthermore, exposure to air pollutant increases the risk of MI-related ventricular arrhythmias and mortality 4. Although elevation of systemic inflammatory biomarkers as IL-6 and C-reactive protein CRP have been associated to short-term exposure to air pollutant 67the precise inflammatory cell pattern associated with the main air pollutants in patients with ischemic heart disease remains undetermined. Air pollution-induced atherosclerotic plaque destabilization may be related to different mechanisms including inflammation, thrombogenicity and endothelial dysfunction 89 Several miRNAs have been what is composition of air class 7 as responsive to air pollution The present study was designed to address two main objectives: firstly, to assess the circulating inflammatory cell changes associated with short term exposure to air pollutants in patients presenting with acute MI and, secondly, to define the precise miRNA signature of MI related to short-term exposure to PM 2.

Our tertiary University Hospital, localized in the central core of Madrid, covers an area of For comparative purposes, we included a control group of patients what is cost concept of accounting stable angina how to solve problem cannot connect to this network underwent cardiac catheterization in our institution during the same recruitment period.

Demographic data and other relevant clinical information were prospectively collected, including cardiovascular risk factors, previous medical history, Killip-Kimball class at presentation, angiographic information, high-sensitive T-troponin and creatine kinase peak. Exclusion criteria were: MI without obstructive coronary artery disease; coronary artery events no related to acute atherosclerotic plaque destabilization e.

All patients underwent systematic circulating inflammatory cell analysis. To select plasma samples for miRNAs analysis, at the end of the recruitment period, patients were sorted out according to PM2. Madrid benefits from a network of 24 meteorological stations recording air pollutants concentration. Each parameter was measured every hour and we obtained the previous h average before hospital admission.

Plasma samples were tested for the presence of hemolysis using the absorbance at nm in a NanoDrop One spectrophotometer Thermo Scientific. Human PBLs were incubated with fluorochrome-conjugated antibodies Supplemental Table 1 for flow cytometry analysis. Membrane staining were performed in phosphate-buffered saline PBS0. Cells were first membrane-stained with anti-CD4.

Gating strategy is shown in Supplemental Fig. Data were analyzed using the global mean normalization method Briefly, after exclusion of values above 36, Cq values were converted to relative quantities RQ and sample specific normalization factor NF was calculated as the geometric mean of the RQs what is composition of air class 7 all expressed targets per sample. Data were expressed as NRQ. A statistical test of overrepresentation for Gene Ontology biological process was performed using the complete Homo what is composition of air class 7 genome as reference list.

Normal distribution of all variables was assessed by Kolmogorov—Smirnov test. Differences between groups were then analyzed using Mann—Whitney U test or Kruskal—Wallis test depending on the number of groups. Results were shown as a correlation matrix. Furthermore, in all patients, the correlation of air pollutants with immune cells was assessed by Spearman test. This study design complied with the recommendations of the Helsinki declaration for investigation with human subjects and was approved by the Can someone fake tinder verification Committee of La Princesa University Hospital, Madrid.

Characteristics of the population what is composition of air class 7 summarized in Table 1. Hypertension, dyslipidemia and diabetes were more common in the stable angina group, while active smoking was more frequent in STEMI group. Otherwise, no differences were observed among the groups in terms of PM 2. The median interquartile range for each air pollutant were the following: The correlation among the air pollutants is shown in Fig.

Correlation map of air pollutants. X no significant correlation. To determine the association of air pollutant exposure and the immune response, we performed correlation analysis with different subsets of T lymphocytes in the whole cohort. Interestingly, although PM 2. We wonder whether these air pollution-associated changes were occurring in the different clinical presentation of atherosclerosis disease.

Correlation of PM 2. Scatter plots are shown. A Association of PM 2. B Association of PM 2. Correlation was assessed by Spearman test. Nevertheless, no significant associations were detected between the analyzed populations and the rest of air pollutants evaluated NO, NO 2 and O 3. Correlations of CO and SO 2 exposure with circulatory immune cells. Scatter plots of significant correlations are shown. C SO 2 exposure was associated with a decrease of total leucocytes count. A total of 31 patients were selected for this analysis, 17 of them exposed to low pollution and 14 exposed to high pollution.

Assuming that the number of microRNAs differentially expressed among different groups would be small, we first calculated the fold change of miRNA expression between high and low pollution. Interestingly, the functional profiling of the microRNA gene targets listed in Table 2 showed an enrichment mainly in biological processes associated with development and morphogenesis of cardiovascular system as well as in several processes of inflammatory response Table 3. Remarkably, nine out of 22 top overexpressed microRNAs regulate the expression of genes involved in both biological processes Fig.

Different colors are used to indicate the targets that are regulated by each miRNA. From all genes identified in miRTarBase as targets of microRNAs listed in Table 2only those with functioonal support were selected to perform the enrichment analysis. Image created with BioRender. Including all clinical presentations in the analysis, high PM 2. Differences were analyzed using Mann—Whitney U test. Subsequently, we analyzed the changes in circulating miRNAs associated to pollution in each clinical presentation.

Circulating levels of miR-let-7f-5p, miRp and miRa-5p are increased in acute myocardial patients exposed to high levels of PM 2. CAD characterizing our population represents a relevant difference with the previous reports, since in most studies healthy participants had been recruited to assess the biological response to air pollutants Nevertheless, healthy participants and patients with CAD may have a different response to exogenous stressors. Besides, previous studies exploring biomarkers in MI patients do not usually include pollution as a variable Plaque destabilization may what is composition of air class 7 to a wide range of clinical presentations, from asymptomatic plaque rupture what is composition of air class 7 erosion to occlusive atherothrombosis.

Thrombogenicity, inflammation, oxidative stress and endothelial function have a large variability in response to exogenous and endogenous stimulus leading to a multifaceted vulnerability milieu that eventually explains the final clinical presentation resulting from acute plaque destabilization Notably, air pollution appears to participate in all the stages of this vulnerable state 8. These findings are consistent with a previous study which analyzed white blood cell changes in patients with chronic respiratory disease exposed to CO in the previous 24 h, observing increased lymphocytes counts Interestingly, IL and IL expression are induced by the activation of aryl hydrocarbon receptors, a transcription factor that is a target for pollution High SO 2 short-term exposure was associated with reduction in the total leucocytes count.

In a previous animal model using inhaled SO 2this finding was also reported Remarkably, both PM 2. In this regard it is important to highlight that the immunosuppressive activity of Treg cells is increased in those cells expressing CD69 Moreover, PM 2. These findings are relevant as numerous studies showed that Tregs deficiency or dysfunction are associated with the development of atherosclerosis 1920 that may be related to the protective effect of Tregs on PM-induced inflammatory response There is no previous data about the effects of air pollution on Treg cell in patients with CAD.

Nevertheless, a similar decreased expression of FOXP3 has been described in atopic children exposed to air pollutants Recently, our group identified the protective role of CD69 for atherosclerotic disease, and peripheral leucocytes from subclinical atherosclerosis individuals express low level of this molecule In this regard, our current data strongly suggest that exposure to air why data security is important in dbms is associated with what is composition of air class 7 reduction in CD69 in T cells.

Interestingly, all of them were linked to gene expression involved in cardiovascular or immune system processes participating in the atherosclerotic disease. The let-7 family is highly expressed in the cardiovascular system, being miR-let-7f related to angiogenesis, ischemia, arrhythmia and heart development Recently, upregulation of miR-let-7f-5p has been documented in activated platelets In a previous report, stress cardiomyopathy showed higher levels of miR-let-7f-5p compared to STEMI, arguing what is composition of air class 7 the observed difference, among others, may be related to alteration of the microcirculation However, no data of pollutant exposure have been reported.

In a large Chinese cohort of general population in primary prevention, lower levels of circulating miRNAp predicted acute MI in the follow up, performing better than hs-CRP. Unfortunately, the study was missing pollution data. In addition, an in vitro what is the hindi meaning of refractive error in rat cardiac fibroblasts documented a possible involvement of miRNAp in the ischemia—reperfusion injury The observed upregulation of miRa was previously reported in steelworkers after short term exposure to PM 2.

In production possibility frontier with example, miRa-5p was previously proposed as a biomarker of PM-induced impaired inflammatory response
