Prevention of early thrombosis in transplanted vein model by encapsulation with tirofiban microneedle drug delivery system.

Early thrombosis following CABG surgery leads to perioperative myocardial infarction, which causes difficulties for clinicians and patients. Moreover, once perioperative myocardial infarction occurs, the mortality rate is extremely high. In recent years, microneedle (MN) drug delivery systems have become a research hotspot with broad clinical application prospects. These systems are capable of achieving sustained, safe, and painless local drug release. In cardiovascular applications, MNs maximize local anticoagulant effects, inhibit endometrial hyperplasia, and reduce systemic side effects. We speculate that a MN drug delivery system can be used to target transplanted veins to inhibit their thrombosis and reduce the incidence of perioperative myocardial infarction after CABG surgery. Therefore, this study developed a hyaluronic acid MN patch loaded with tirofiban and conducted preliminary physicochemical tests. The safety, efficacy, biocompatibility, and targeting of the MN system were evaluated using in vitro and in vivo experiments using a jugular vein transplantation model. The results indicate that the MN system has excellent physical properties, safety, effectiveness, biocompatibility, and strong targeting, which can effectively inhibit early local thrombus formation. In addition, the observation of early postoperative endometrial hyperplasia activation provides a foundation for future research.&#xD.

Effectiveness of Vibrapep (OPEP) on Pulmonary functions in phase one of cardiac rehabilitation-A Randomized controlled trial

Background and Aims: According to the WHO report 2022, coronary artery disease is the most prevalent cardiac disease worldwide. Impaired respiratory muscle function, increased secretions and reduced vital capacity are pulmonary complications commonly associated with CABG and Valve replacement surgeries. The purpose of this study was to compare the effect of Vibrapep and standard phase one of cardiac rehabilitation exercises on pulmonary functions. Methods: A Randomized Controlled Trial was conducted on 46 participants. Participants were randomly allocated into two groups, Vibrapep and phase one of cardiac exercises were given to Group A (n = 23), while Group B (n = 23) received only phase one cardiac rehabilitation exercises. The intervention was administered for twice a day for 5 days. Outcome measures such as Sputum volume, maximal inspiratory and expiratory pressure, thoracic expansion, SPO2 level, blood pressure and Peak expiratory flow rate were evaluated at baseline and on 5th day of the study. Results: Wilcoxon test of within-group analysis revealed statistically significant improvements in all parameters for both the interventional and control groups (p<0.05*), except in diastolic blood pressure, whereas, between group analysis done using Mann Whitney U test also showed statistical improvement in both groups on all parameters with (p<0.05*). Conclusion: Vibrapep exhibited to be an effective bronchial hygiene therapy in phase one of cardiac rehabilitation with respect to enhancing pulmonary functions such as sputum reduction, chest expansion, improved respiratory pressure’s, Peak Expiratory Flow Rate along with Cardiac rehabilitation.

The safety of cell saver washing all shed mediastinal blood before re-transfusing it to the patient.

Cardiotomy suction blood is used in cardiopulmonary bypass (CPB) surgery to maintain blood volume in the CPB system, although it is known to contain micro emboli, cytokines and free plasma hemoglobin. Our aim was to investigate whether cell saver washing the cardiotomy suction blood before re-transfusing it is safe. This is a retrospective study of 1671 elective coronary artery bypass patients, 209 of whom had their pericardial blood processed in a cell saver (Ce-S group). PS matching was performed with patients who had their pericardial blood returned back to the CPB-system by the cardiotomy suction (Ca-S group). Perioperative transfusion requirements, surgical outcome, postoperative lab data and mortality were then compared. There were no differences in baseline characteristics or EuroSCORE between the groups. The number of patients requiring transfusions did not differ, but the patients in the Ca-S group received more platelets (0.34 ± 1.0 vs 0.16 ± 0.7 units, p = .03) than in the Ce-S group. CRP (c-reactive protein) levels at day 2 and 4 were higher in the Ca-S group (174.8 ± 67.2 and 148.9 ± 74.3mg/L vs 160.1 ± 64.6 and 125.9 ± 67.2mg/L, p = .03, p = .002) and so were ASAT (aspartate aminotransferase) levels (0.97 ± 0.8 vs 0.81 ± 0.6μkat/L, p = .03). Mortality, postoperative ventilation time, stroke, mediastinal infections and length of stay in the ICU were the same in both groups. In this retrospective study of patients undergoing elective CABG surgery, washing the cardiotomy suction blood before re-transfusion was not associated with higher risk of allogenic blood transfusion, postoperative stroke, mediastinal infections, or 30- and 365-days mortality.

Statins have profound effects on the epicardial fat transcriptome

Abstract Background Epicardial adipose tissue (EAT) has direct contact with the myocardium, which enables a common microcirculation allowing bidirectional signaling between the tissues. It is possible that a change in the balance of protective and damaging mediators produced by EAT is a major driver for myocardial dysfunction. Notably, EAT volume and thickness associate with increased pro-inflammatory secretome and with coronary artery disease (CAD). Purpose This aim of this study was to analyze the total transcriptome in EAT and relate putative differences between patient groups to metabolic parameters as well as ongoing medications. Methods Between 2011 and 2016, 44 patients (mean age 68.0 years, 18.2% women) had a biopsy taken from the epicardial fat during coronoray by-pass surgery (CABG, n=36), or during elective aortic valvular replacement due to aortic stenosis (AVR, n=8). RNA from epicardial fat biopsis was extracted and sequenced. Differentially expressed genes were obtained by custom scripts that performed a negative binomial distribution test on effective counts. Multivariate regression analysis with orthogonal partial least-squares-discriminant analysis (OPLS-DA) was applied to extract and interpret the systematic variation in the resolved RNA sequencing profiles. To identify enrichment of biologically relevant functional gene sets, our data were entered in evidence-based network enrichment analysis (EviNet). Results The CABG surgery was performed approximately 7 days after an acute coronary event (75% acute MI), and 44% of them had previously known CAD. None of the AVR cases had significant CAD. At surgery, 97% of the CABG cases were prescribed statins, and 36% of them had statins alredy before the actual admission (long-term statin treatment). 63% of the AVR cases were on statins at admission. The OPLS analysis revealed only one medication with significant outcome, i.e., patients with long-term treatment with statins (n=18) versus patients without (n=26). Long-term statin treatment associated with down-regulated gene expression involved in beta-oxidation and triglyceride biosynthesis whereas gene expression involved in extracellular matrix organization were up-regulated. Gene expression involved in MHC class II presentation and interferon signalling were also reduced in patients with long-term treatment with statisn. A downregulation of genes in the interleukin- and complement cascade genes among CABG patient (versus AVR patients) without long-term statin treatment showed normal levels in statin pretreated patients. Conclusion Long-term statin treatment has a major influence on transcriptional regulation of genes involved in beta-oxidation, triglyceride biosynthesis, extracellular matrix composition, MHC class II presentation and interferon signalling in epicardial adipose tissue. These findings support important metabolic and immune effects of statins beyond the lipid-lowering function.

Artificial intelligence systems for predicting disease outcomes in chronic ischemic heart disease patients who have undergone cardiac surgery in respect of anemic syndrome (review).

Materials and methods. The PubMed and RSCI databases were analyzed covering the period of 2000-2023. 906 articles were found using the keywords “artificial intelligence”, “anemia”, coronary artery disease”, “hemoglobin”, “cardiac surgery”, of which 38 met the criteria for inclusion in the analysis. Results. In a number of countries around the world, artificial intelligence (AI) systems have now been created to predict the course of IHD, however, at the moment, data have been published on the single system with AI elements, presented by the developers of the University of Turin (Italy). It has the functionality of predicting the course of IHD and complications of invasive procedures for IHD against the background of anemic syndrome, based on the use of the HAS-BLEED scale. The increase in the number of CABG operations determines the importance of further research into their long-term results and the development of programs for their management, which will take into account such factors that are important for choosing a strategy for their management and the possibility of influencing the risks of an unfavorable prognosis. This review presents published data on the developed and used digital products based on artificial intelligence intended for the management of patients with coronary artery disease, including taking into account basic hematological parameters. Conclusion. Analysis of existing developed AI systems showed a focus on solving prognostic issues. At the same time, in our opinion, the range of analyzed parameters is not wide enough, in particular, taking into account the presence of anemia, which plays one of the key roles in modifying the risk of adverse outcomes (coronary deaths, repeated acute coronary events, progression of CHF).

IMPACT OF ADVANCED HEMODYNAMIC MONITORING ON MYOCARDIAL REVASCULARIZATION SURGERY IN HIGH-RISK PATIENTS

Coronary artery bypass grafting is a critical procedure for patients with advanced coronary disease, especially those classified as high risk due to comorbidities such as heart failure, hypertension and diabetes. Advanced hemodynamic monitoring has proved essential in this context, allowing continuous and accurate surveillance of cardiac and vascular parameters, which can reduce intra- and post-operative complications. This abstract aims to assess the impact of advanced hemodynamic monitoring during coronary artery bypass graft surgery in high-risk patients. The aim is to explore the advantages of this type of monitoring, the technologies used and the benefits in terms of clinical outcomes and reduction of complications. This is a literature review with a qualitative approach, carried out in the PubMed, SciELO, LILACS, BVS and Google Scholar databases. In order to optimize the search, descriptors such as Hemodynamic Monitoring, Cardiac Surgery, High Risk Patients and Fluid Management were used. For time delimitation, the research considered publications between the years 2019 and 2022, a period that reflects the latest advances in hemodynamic monitoring technologies in high-risk cardiac surgeries. Advanced hemodynamic monitoring includes the use of devices such as the pulmonary artery catheter and non-invasive bioimpedance systems, which provide real-time data on cardiac output, blood pressure, oxygen saturation and systemic vascular resistance. In high-risk patients, these devices allow for precise adjustments in the administration of fluids and vasoactive drugs, promoting better hemodynamic stability. Studies indicate that this approach reduces the incidence of serious complications, such as cardiogenic shock and arrhythmias, optimizing post-operative recovery. Therefore, advanced hemodynamic monitoring is a crucial tool in CABG surgeries, especially for high-risk patients. Its implementation improves intraoperative management, reducing the risk of complications and promoting better clinical outcomes. Therefore, its use should be considered an integral part of strategies for complex cardiac surgeries.

Body mass index and its impact on outcomes in CABG surgery: the paradox of obesity and underweight risks.

Objective: To explore the impact of BMI on the short-term mortality and morbidity of patients undergoing CABG. Study Design: Retrospective Cross Sectional study. Setting: Department of Cardiac Surgery Rehman Medical Institute, Peshawar, Pakistan. Period: 1st June 2017 to 31st December 2022. Methods: The data was collected from the data base of the cardiac surgery department. Results: Total of 2599 isolated CABG patients were included with mean age of 57.86±9.2 years. The majority was overweight (42%). Approximately 78.1% were male. Hypertension was our dominant co-morbidity (68.7%) followed by dyslipidemia (65.4%) & DM (50.1%). Majority of patients had NYHA-III symptoms (51.2%). A significant proportion of individuals who are classified as underweight are elderly. Generally, there is a significant increasing trend of DM & HTN incidence with increasing BMI. In terms of intra-operative parameters there is increasing trend of intra-operative transfusions and higher rate of IABP insertion in underweight patients. Generally the underweight patients has the higher trend of adverse outcomes (e.g., prolonged mechanical ventilation, blood product requirement, reopening & re-intubation), but not significant. However, they have significantly longer mechanical ventilation time compared to normal. On the other extreme, morbidly obese patients had the highest in-hospital mortality (11.3%) while overweight had the lowest (2.6%) with a P-value of 0.008. Multivariate regression analysis showed that mean age (P 0.034), cross-clamp time (P 0.018) & mechanical ventilation (P <0.001) were significantly associated with in-hospital mortality. Conclusion: Morbidly obese patients undergoing CABG surgery face significantly higher in-hospital mortality rate, conversely overweight patients exhibits the lowest mortality rates confirming a partial obesity paradox. However, underweight patients experience the worst outcomes, including increased requirements for postoperative blood transfusions, a higher incidence of surgical reopening, and significantly extended mechanical ventilation hours, which indicates either extreme of BMI group is associated with worst outcomes.

The Role of Preoperative Breathing Exercises in Reducing Postoperative Respiratory Complications in Coronary Artery Bypass Grafting: A Comparative Review of On-Pump and Off-Pump Techniques

Objectives: This review aims to evaluate the efficacy of preoperative breathing exercises in reducing postoperative respiratory complications, particularly respiratory failure, in patients undergoing CABG surgery. The review also compares the outcomes of these interventions in patients undergoing on-pump (ONCAB) versus off-pump (OPCAB) procedures. Methodology: A comprehensive literature search was conducted across multiple databases, including PubMed, Scopus, and Cochrane Library, to identify studies that examined the impact of preoperative breathing exercises on respiratory outcomes in CABG patients. The review focused on randomized controlled trials (RCTs) that compared the effectiveness of these exercises in ONCAB and OPCAB settings. Results: The review identified several studies supporting the role of preoperative breathing exercises in reducing postoperative respiratory complications. These exercises, including diaphragmatic breathing, incentive spirometry, and deep breathing, were associated with improved pulmonary outcomes, such as reduced incidence of respiratory failure, shorter durations of mechanical ventilation, and decreased hospital length of stay. While the overall results were positive for both ONCAB and OPCAB patients, variations were observed based on the surgical technique and patient-specific factors. Conclusion: Preoperative breathing exercises are an effective intervention for reducing the risk of postoperative respiratory complications in CABG patients. The benefits were observed in both ONCAB and OPCAB procedures, with particular advantages noted in the ONCAB group due to the higher baseline risk. Further research is needed to optimize these interventions, considering the individualized nature of patient responses and the specific characteristics of each surgical technique.

Spontaneous avulsion of left internal mammary artery graft a complication of coronary artery bypass surgery: case report and review of the literature

BackgroundCoronary artery bypass grafting (CABG) surgery is a common procedure for managing multi-vessel coronary artery disease to revascularize the myocardium. Among the various conduits used, the left internal mammary artery (LIMA) is preferred due to its better long-term patency rate. However, CABG procedures involving LIMA may result in rare but serious complications, such as avulsion of the LIMA post-CABG, which leads to disruption of blood flow to the myocardium and the development of fatal cardiac tamponade.Case presentationWe hereby present a unique case of spontaneous avulsion of a LIMA graft to the left anterior descending artery (LAD) away from the site of anastomosis, twenty-four hours following CABG surgery in a 67-year-old male patient. Emergency re-exploration and repair of the LIMA with interposition vein graft were performed and resulted in successful stabilization of the patient’s critical condition. However, this was followed by a complicated recovery period involving atrial fibrillation, acute kidney injury, and wound infection.ConclusionAvulsion of LIMA graft following CABG is rare, yet a fatal complication that requires high clinical suspicion and prompt management. Avulsion has been reported a few times in literature following both minimal invasive and conventional CABG. Understanding the etiology, clinical presentation, and management of this complication is crucial to avoid catastrophic outcomes.

Abstract: This study examined 204 patients undergoing CABG surgery at Tehran Heart Center between Ordibehesht 1402 and Ordibehesht 1403 for postoperative complications. Objective: Investigation and Comparison of Complications in Single-Wire and Double-Wire Sternal Closure Methods Following Open Heart Surgery in Patients Referred to Tehran Heart Center from May 2023 to May 2024 Methods: Patients were divided into two groups of 102 each, with Group 1 undergoing sternal closure using a single-wire method and Group 2 using a double-wire method. Results: All patients were discharged after surgery and followed up for one year. The age range was 44 to 75, with 21 patients aged 45-55 (10%), 133 patients aged 55-65 (65%), and 50 patients aged 65-75 (24%). Both groups had similar age distributions. Of the total patients, 78 were female (38.2%) and 126 were male (61.8%), indicating a higher prevalence of cardiovascular disease in males.

Comparison of the effect of telephone follow-up with social network follow-up program on self-efficacy and depression in patients undergoing coronary artery bypass graft surgery: A randomized controlled trial

IntroductionCoronary artery bypass graft (CABG) surgery is a common procedure to improve blood flow to the heart muscles, but patients often face challenges during the recovery period. Self-efficacy and depression play crucial roles in patient outcomes. Telephone follow-up and social network follow-up have been introduced as interventions to enhance self-efficacy. This study aims to compare the effectiveness of telephone follow-up and social network follow-up on self-efficacy and depression in CABG patients. MethodThe study is a single-blinded, randomized controlled trial conducted at Shahid Rajaee Heart Hospital in Tehran, Iran. The sample size was determined to be 99 patients who met the inclusion criteria. Data were collected using a demographic questionnaire, Sullivan's cardiac self-efficacy questionnaire, and the Beck Depression Inventory (BDI). Participants were assigned to three groups: control, telephone follow-up, and WhatsApp follow-up using randomization. Data were analyzed using IBM SPSS Statistics for Windows, version 25 (IBM Corp., Armonk, N.Y., USA). ResultsThe results revealed significant improvements in self-efficacy and reductions in depression scores for both the telephone and WhatsApp follow-up groups compared to the control group following the intervention (p < 0.001). Additionally, the mean self-efficacy score was higher and the mean depression score was lower in the WhatsApp follow-up group than in the telephone follow-up group after the intervention (p < 0.001). DiscussionThe findings provide valuable insights for healthcare professionals in choosing appropriate interventions to enhance patients' self-efficacy levels and improve mental health outcomes. Both telephone follow-up and social network follow-up interventions have their own advantages and can be effective in supporting patients' recovery after CABG surgery.

A Prospective Study on Activities of Daily Living, Comfort, Body Image, and Cardiac Symptoms in Coronary Artery Bypass Patients

BackgroundA coronary artery bypass graft procedure reduces mortality for cardiovascular patients, but those undergoing it often face negative body perception, loss of daily activities, and lingering symptoms, hindering full functional recovery and comfort. AimTo compare the comfort level, activities of daily living, and body image based on certain characteristics of patients at baseline, (ii) Evaluate changes over time in levels of discomfort, activities of daily living, body image, and cardiac symptoms before and after CABG surgery within three months. MethodThis descriptive prospective cohort study comprised 50 patients scheduled for coronary artery bypass surgery. The study examined cardiac symptoms, comfort levels, daily activities, and multidimensional body-self relationships as its outcomes. ResultsA Friedman test revealed that patients' body image, comfort levels, activities of daily living, and each heart symptom were significantly influenced by the time of day. According to this study, patients most frequently reported experiencing exhaustion, depression, and worry as cardiac symptoms. Only the comfort level exhibited a high correlation with each heart symptom, as indicated by Spearman's rho analysis. ConclusionThe body image, comfort level, activities of daily living, and cardiac symptoms of patients changed over time. Therefore, regular assessments of these symptoms during the pre- and post-operative periods could offer valuable insights into patients' needs. This information can be instrumental in developing interventions that address patients' well-being and may positively impact patient outcomes.

Unfractionated heparin reverses aspirin inhibition of platelets during coronary artery bypass graft surgery

Unfractionated heparin (UFH) is an effective antithrombotic during surgery but has known adverse effects, in particular on platelets. A marked increase in platelet responsiveness has previously been observed in patients within minutes of receiving UFH, despite adequate inhibition by aspirin prior to heparin. We studied this phenomenon in patients undergoing cardiac artery bypass grafting (n = 17) to determine whether the effects of heparin were systemic or platelet-specific. All patients’ platelets were fully inhibited by aspirin prior to surgery, but within 3 min of receiving heparin spontaneous aggregation and responses to arachidonic acid (AA) and ADP increased significantly (p ≥ 0.0002), and activated platelets were found in the circulation. While there was no rise in thromboxane in the plasma following heparin, levels of the major platelet 12-lipoxygenase product, 12-HETE, rose significantly. Mixing experiments demonstrated that the changes caused by heparin resided primarily in the platelets, while addition of AA pathway inhibitors, and analysis of oxylipins provided evidence that, following heparin, aggregating platelets regained their ability to synthesise thromboxane. These findings highlight potentially unrecognised pro-thrombotic and pro-inflammatory changes during CABG surgery, and provide further evidence of adverse effects associated with UFH.

Long Term Survival Benefits of Different Conduits Used in Coronary Artery Bypass Graft Surgery- A Single Institutional Practice Over 20 Years.

This study determined hazard factors and long-term survival rate of total arterial coronary artery bypass graft surgery over 20 years in an extensively large, population-based cohort. A total of 2979 patients who underwent isolated CABG from April 1999 to March 2020 were studied in 4 groups- Group-A (bilateral internal mammary artery ± radial artery), Group-B (single internal mammary artery + radial artery ± saphenous vein), Group-C (single internal mammary artery ± saphenous vein; no radial artery), and Group-D (radial artery ± saphenous vein; no internal mammary artery). The study endpoints analysed the correlation between the number and types of grafts with the survival time following isolated CABG surgery. The total arterial revascularization (Group A) group had an admirable mean long-term survival of ~19 years, compared to 18.6 years (Group B), 15.86 years (Group C), and 10.99 years (Group D). A Kaplan-Meier curve demonstrated confidence interval (CI) for study groups- (95% CI 18.33-19.94), (95% CI 18.14-19.06), (95% CI 15.40-16.32), and (95% CI 9.61-12.38) in Group A, B, C, D respectively. In the Holm-Sidak method analysis, significant associations existed between the number of arterial grafts and the long-term outcome. A statistically significant (P≤0.05) long-term survival advantage for arterial grafting was demonstrated, especially total arterial revascularisation over all other combinations except single internal mammary artery + radial artery grafting. In this series, over 20 years, total arterial CABG use has excellent long-term survival, achieving complete myocardial revascularisation. There is no significant difference between the BIMA group and SIMA with radial artery. However, there is a reduced survival with decreased use of arterial conduits.

Incidence of Acute Kidney Injury (AKI) for Patients Underwent CABG Operation Either On-Pump versus Off-Pump

Unraveling the Predictors for Delirium and ICU Stay Duration in Patients with Heart Failure and Reduced Ejection Fraction (HFrEF) Undergoing Coronary Artery Bypass Grafting-A Multicentric Analysis.

Objective: This study assesses predictors for postoperative delirium (POD) and ICU stay durations in HFrEF patients undergoing CABG, focusing on ONCAB versus OPCAB surgical methods. Summary Background Data: In cardiac surgery, especially CABG, POD significantly impacts patient recovery and healthcare resource utilization. With varying incidences based on surgical techniques, this study provides an in-depth analysis of POD in the context of HFrEF patients, a group particularly susceptible to this complication. Methods: A retrospective analysis of 572 patients who underwent isolated CABG surgery with a preoperative ejection fraction under 40% was conducted at four German university hospitals. Patients were categorized into ONCAB and OPCAB groups for comparative analysis. Results: Age and Euro Score II were significant predictors of POD. The ONCAB group showed higher incidences of re-sternotomy (OR: 3.37), ECLS requirement (OR: 2.29), and AKI (OR: 1.49), whereas OPCAB was associated with a lower incidence of delirium. Statistical analysis indicated a significant difference in ICU stay durations between the two groups, influenced by surgical complexity and postoperative complications. Conclusions: This study underscores the importance of surgical technique in determining postoperative outcomes in HFrEF patients undergoing CABG. OPCAB may offer advantages in reducing POD incidence. These findings suggest the need for tailored surgical decisions and comprehensive care strategies to enhance patient recovery and optimize healthcare resources.

Myocardial Revascularisation in Calcified Aorta in CKD Patient with Help of ENCLOSEII Device, A Bail Out Situation

In this case, a 56 years dialysis dependent patient presented with complaints of angina at rest for 2 weeks after which she was thoroughly evaluated and was diagnosed with coronary artery disease with calcified aorta along with calcification of other vessels also, following which she was planned for CABG surgery. The unclampable ascending aorta (UAA) is a condition increasingly encountered during CABG procedures[1]. Aging of the population and the increase in patients on dialysis have led to an increasing frequency of “porcelain aorta”[2]. The use of the no-touch technique is associated with a high perioperative risk but a superior possibility of complete revascularisation, whereas the adoption of the no-pump strategy ensures a smoother postoperative course at the expense of a higher incidence of ischemia recurrence[3]. Enclose-II anastomosis assist device was originally developed as an ancillary device for proximal anastomosis in off-pump coronary artery bypass grafting (OPCABG), to assist anastomosis for the vascular grafts without clamping the ascending aorta[3]
