The aim of this study was to identify potential genes that may reduce the inflammatory response and complications after CPB. The GSE132176 dataset was selected from the Gene Expression Omnibus (GEO) database and included 10 patients with tetralogy of Fallot and 10 patients with an atrial septal defect who underwent CPB surgery. TSV files were downloaded after GEO2R processing. Protein-protein interaction analysis of common differentially expressed genes (DEGs) was performed using the Search Tool for the Retrieval of Interacting Genes. Gene modules and hub genes were visualized in the protein-protein interaction network using Cytoscape. Enrichment analysis was performed for all important DEGs, modular genes, and hub genes. A total of 72 DEGs were screened, including two functional and one hub gene module. FOS modular genes were primarily enriched in NGF-stimulated transcription, spinal cord injury, and PID AP1 pathway. The ATF3 modular gene was mainly enriched in cytomegalovirus infection and transcriptional misregulation in cancer. Hub gene modules were primarily enriched in the PID AP1 pathway, positive regulation of pri-miRNA transcription by RNA polymerase II, and the PID ATF2 pathway. FOS, JUN, ATF3, and EGR1 were the four most important hub genes; the top three hub genes were involved in the formation of AP-1 and enriched in the AP-1 pathway. Finally, we measured the expression levels of these four genes in patients undergoing CPB via qRT-PCR, and the results were consistent with those obtained in bioinformatic analysis. FOS, JUN, ATF3, and EGR1 and the AP-1 pathway may play key roles in inflammation and complications caused by CPB.","PeriodicalId":257138,"journal":{"name":"The heart surgery forum","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123851850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But, in patients with severe left ventricular dysfunction (ischemic cardiomyopathy), the result of CABG is different from those with normal left ventricular function. The coronary artery disease pattern in the Indian subconti-nent is different from the western world, due to the diffuse nature of coronary involvement, the smaller size of native vessels, increased prevalence of diabetes mellitus and other risk factors, and more prevalence of severe left ventricular dysfunction. Most of the studies regarding the surgical outcomes in ischemic cardiomyopathy come from western countries. This study attempts to assess the outcomes of surgical management of ischemic cardiomyopathy in the Indian subcontinent.\u0000\u0000\u0000METHODS\u0000A single-center retrospective cohort study was conducted at Sree Chitra Tirunal Institute for Medical Sciences and Technology, Thiruvananthapuram. The data of CAD pa-tients, who underwent surgical coronary revascularization for severe LV dysfunction from January 2010 to December 2014, were collected from the hospital records and through tele-phonic interviews in a structured study proforma. A total of 146 patients satisfied the criteria and were followed up for a period of 5 years.\u0000\u0000\u0000RESULTS\u0000The mean age of the study population was 55.6 (8.8) years. Male preponderance was observed (94.52%; N = 138). CABG alone was done in 62.3% (N = 91) of the study partici-pants. CABG with linear plication was done in 23.3% (N = 34), CABG with MV repair in 7.5% (N = 11), and CABG with DORS in 6.8% (N = 10). The majority of patients (N = 54, 37%) received 4 grafts. Thirty-day mortality observed in the study population was 11 (7.5%). The causes documented were cardiac causes in 9 (82%), cerebrovascular events in one (9%), and septicemia in one (9%). The mean of 5-year survival of the study population was 94.2 (3.5) months with 95% CI 87.32, 101.13. There was a substantial improvement in the degree of mitral regurgitation.

Studies have shown that even a slight increase in serum creatinine levels after cardiac surgery significantly affects the mortality and morbidity of these patients.\u0000\u0000\u0000AIM\u0000This study sought to determine the predictors and incidence of acute kidney injury (AKI) in patients older than 70 years undergoing elective valvular surgery.\u0000\u0000\u0000METHODS\u0000Prospective study included 156 patients scheduled for elective cardiac surgery requiring cardiopulmonary bypass (CPB) at Dedinje Cardiovascular Institute between January and September 2019. Isolated valvular surgery was performed in 87 patients, while the remaining 69 patients underwent combined coronary and valvular surgery. The development and stage of CSA-AKI were diagnosed, according to Kidney Disease Improving Global Outcome (KDIGO) criteria. Predictors and incidence of CSA-AKI development were assessed using univariate binary logistic regression analysis.\u0000\u0000\u0000RESULTS\u0000The incidence of CSA-AKI was 17.3%. CSA-AKI stage 1 was diagnosed in 25 patients  (16.02%). CSA-AKI stage 2 was noted in one patient (0.64%), as well as stage 3 (0.64%). In six patients (3.85%), renal replacement therapy (RRT) was required. Using univariate binary logistic analysis, the following parameters were identified as predictors for CSA-AKI development: duration of cardiopulmonary bypass (OR 1.01; CI 95% (1.01-1.02); P = .002), duration of aortic clamping (OR 1.02; CI 95% (1.01-1.03); P = .002), lactate levels during the intensive care unit (ICU) stay (OR 1.33; CI 95% (1.04-1.70); P = .026), duration of mechanical ventilation (MV) (OR 1.03; CI 95% (1.1-1.07); P = .014), the use of inotropic drugs (adrenaline, dobutamine) (OR 0.38: CI 95% (0.16-0.9); P = .026; and OR 0.23; CI 95% (0.1-0.56); P = .0019, respectively), and the use of diuretics (OR 0.24; CI95% (0.06-095); P = .041). Using Mann-Whitney U test for independent samples show that the group of patients who developed CSA-AKI had significantly longer duration of hospitalization (Z = -2.751); P = .006), prolonged ICU stay (Z = -4.160; P < .001), and need for prolonged mechanical ventilation (Z = -4.411; P < .001).\u0000\u0000\u0000CONCLUSION\u0000Independent predictors for AKI development after valvular surgery in patients older than 70 years are prolonged mechanical ventilation and increased lactate values, while the use of diuretics after surgery reduces the incidence of AKI.

The patients were divided into a high-risk group (N = 31), medium-risk group (N = 32), and low-risk group (N = 20), according to the guidelines for diagnosis and treatment of acute pulmonary embolism issued by ASH in 2020. The clinical characteristics, treatment, and prognosis of the three groups were summarized, and the severity of the patients could be predicted and the related risk factors affecting prognosis were analyzed.\u0000\u0000\u0000RESULTS\u0000There were significant statistical differences in respiratory rate, syncope as the first symptom, bilateral pulmonary embolism, and APACHE-II score among the three groups (P < 0.05). There were significant statistical differences in the laboratory indexes, such as BNP, cTnI and D-dimer before and immediately after APE among the three groups (P < 0.05). There were significant statistical differences in cTnI and D-dimer among the three groups (P < 0.05). By pairwise comparison, it was found that there were significant statistical differences between the high-risk and low-risk groups in the immediate test indexes of APE, such as BNP, D-dimer, lower extremity vascular ultrasound abnormalities, and ECG abnormalities (P < 0.05), while there was no significant statistical difference between the medium-risk and low-risk groups in the immediate test indexes of APE (P > 0.05). However, in the medium-risk group, the laboratory indexes tended to increase, in terms of treatment and outcome, thrombolysis rate, and inferior vena cava filter implantation rate. ICU stay (> 2 weeks) of the high-risk group was significantly higher than those of the other two groups, with significant statistical difference (P < 0.05). Logistic regression analysis showed that respiratory rate (or = 1.778,95% CI 1.043-3.032, P = 0.034), D-Dimer (or = 1,95% CI 1.0-1.0, P = 0.006), and APACHE-II score (or = 1.879,95% CI 1.398-2.527, P = 0.000) were independent risk factors for predicting the severity of APE patients in the ICU ward.\u0000\u0000\u0000CONCLUSION\u0000Acute pulmonary embolism (APE) is a critical disease in ICU. By monitoring BNP, cTnI and D-dimer, we can identify critical patients with APE early. In addition, we found that respiratory rate, D-dimer, and APACHE-II score were independent risk factors for predicting the severity of APE patients in the ICU. Clinically, APE can be identified early. The diagnosis, treatment rate, and prognosis can be improved by monitoring these indicators.","PeriodicalId":257138,"journal":{"name":"The heart surgery forum","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116667841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
