Background: This study presents an innovative approach to cardiovascular disease (CVD) risk prediction based on a comprehensive analysis of clinical, immunological and biochemical markers using mathematical modelling and machine learning methods. Baseline data include indices of humoral and cellular immunity (CD59, CD16, IL-10, CD14, CD19, CD8, CD4, etc.), cytokines and markers of cardiovascular disease, inflammatory markers (TNF, GM-CSF, CRP), growth and angiogenesis factors (VEGF, PGF), proteins involved in apoptosis and cytotoxicity (perforin, CD95), as well as indices of liver function, kidney function, oxidative stress and heart failure (albumin, cystatin C, N-terminal pro B-type natriuretic peptide (NT-proBNP), superoxide dismutase (SOD), C-reactive protein (CRP), cholinesterase (ChE), cholesterol, and glomerular filtration rate (GFR)). Clinical and behavioural risk factors were also considered: arterial hypertension (AH), previous myocardial infarction (PICS), aortocoronary bypass surgery (CABG) and/or stenting, coronary heart disease (CHD), atrial fibrillation (AF), atrioventricular block (AB block), and diabetes mellitus (DM), as well as lifestyle (smoking, alcohol consumption, physical activity level), education, and body mass index (BMI). Methods: The study included 52 patients aged 65 years and older. Based on the clinical, biochemical and immunological data obtained, a model for predicting the risk of premature cardiovascular aging was developed using mathematical modelling and machine learning methods. The aim of the study was to develop a predictive model allowing for the early detection of predisposition to the development of CVDs and their complications. Numerical methods of mathematical modelling, including Runge–Kutta, Adams–Bashforth and backward-directed Euler methods, were used to solve the prediction problem, which made it possible to describe the dynamics of changes in biomarkers and patients’ condition over time with high accuracy. Results: HLA-DR (50%), CD14 (41%) and CD16 (38%) showed the highest association with aging processes. BMI was correlated with placental growth factor (37%). The glomerular filtration rate was positively associated with physical activity (47%), whereas SOD activity was negatively correlated with it (48%), reflecting a decline in antioxidant defence. Conclusions: The obtained results allow for improving the accuracy of cardiovascular risk prediction, and form personalised recommendations for the prevention and correction of its development.

Background: Sternal wound infections (SWIs) remain a significant complication following cardiac surgery. Inflammatory and nutritional status are increasingly recognized as key contributors to their development. This study aimed to investigate the predictive utility of immunonutritional biomarkers and to evaluate the protective effect of combining sternal irrigation with an antibiotic-impregnated membrane. Methods: This retrospective cohort study included 480 patients undergoing off-pump coronary artery bypass grafting. Patients were categorized based on sternal management strategy (standard closure or local prophylaxis using gentamicin-enriched irrigation combined with an antibiotic-impregnated fascia lata membrane) and according to the severity of SWIs, classified as superficial or deep. Inflammatory and nutritional markers—including C-reactive protein (CRP), neutrophils, lymphocytes, albumin, neutrophil-to-lymphocyte ratio (NLR), C-reactive protein-to-albumin ratio (CAR), and prognostic nutritional index (PNI)—were assessed at three time points: preoperatively, on postoperative day 3, and after week 1. Results: SWIs were observed in 93 patients, including 75 superficial and 18 deep infections. The combined prophylactic approach was associated with a nearly 1.8-fold reduction in deep SWIs (OR: 0.55; 95% CI: 0.15–0.87) and a modest reduction in superficial infections (OR: 0.89; 95% CI: 0.5–1.3; p = 0.061). Threshold values of 3.75 for preoperative NLR, 9.8 for ΔNLR, and 16.7 for ΔCAR demonstrated strong predictive capacity for identifying patients at increased risk of developing deep SWIs. Patients receiving local prophylaxis exhibited significantly lower CRP, NLR, and CAR values and higher PNI levels at all time points. Conclusions: The combination of sternal irrigation and local antibiotic prophylaxis appears to confer protection against SWIs, potentially by mitigating postoperative inflammation. Immunonutritional biomarkers offer a promising means for early risk stratification. To confirm their clinical utility and broader applicability, these results should be validated in prospective, multicenter studies encompassing a wider range of cardiac surgical procedures.

Background and Objectives: The perioperative use of beta-blockers remains controversial due to conflicting evidence of their risks and benefits. The aim of this study was to evaluate the association between chronic beta-blocker (bb) therapy and perioperative cardiac events in non-cardiac surgeries using 24 h continuous Holter monitoring. Materials and Methods: A prospective observational study was conducted on patients undergoing elective or emergency non-cardiac surgery at a Romanian tertiary care hospital. The patients were divided into two groups: G1 (not receiving Bb) and G2 (on chronic Bb). The incidences of perioperative cardiac events, such as severe bradycardia (<40 b/min), new-onset atrial fibrillation (AF), extrasystolic arrhythmia (Ex), and sustained ventricular tachycardia (sVT) and arterial hypotension, were compared between the two groups using clinical, electrocardiography (ECG), and Holter ECG data. Beta-blocker indications, complications, and outcomes were analyzed using chi-squared tests and logistic regression. Results: A total of 100 consecutive patients (63% men, mean age of 53.7 years) were enrolled in the study. G2 included 30% (n = 30) of patients on chronic beta-blocker therapy. The indications included atrial fibrillation (46.7%, n = 14), arterial hypertension (36.7%, n = 11), extrasystolic arrhythmias (10%, n = 3), and chronic coronary syndrome (6.6%, n = 2). Beta-blocker use was significantly associated with severe bradycardia (n = 6; p < 0.001) in G2, whereas one patient in G1 had bradycardia, and 15 and 1 patients had hypotension (p < 0.001) in G1 and G2, respectively. The bradycardia and arterial hypotension cases were promptly treated and did not influence the patients’ prognoses. The 14 patients with AF in G2 had a 15-fold higher odds of requiring beta-blockers (p < 0.001, odds ratio (OR) = 15.145). No significant associations were found between beta-blocker use and the surgery duration (p = 0.155) or sustained ventricular tachycardia (p = 0.857). Ten patients developed paroxysmal postoperative atrial fibrillation (AF), which was related to longer surgery durations (165 (150–180) vs. 120 (90–150) minutes; p = 0.002) and postoperative anemia [hemoglobin (Hg): 10.4 (9.37–12.6) vs. 12.1 (11–13.2) g/dL; p = 0.041]. Conclusions: Patients under chronic beta-blocker therapy undergoing non-cardiac surgery have a higher risk of perioperative bradycardia and hypotension. Continuous Holter monitoring proved effective in detecting transient arrhythmic events, emphasizing the need for careful perioperative surveillance of these patients, especially the elderly, in order to prevent cardiovascular complications These findings emphasize the necessity of tailored perioperative beta-blocker strategies and support further large-scale investigations to optimize risk stratification and management protocols.

Background: Postoperative delirium (POD) is a neurocognitive syndrome affecting patients undergoing surgery. It is a frequent complication of coronary artery bypass grafting (CABG) and is associated with higher morbidity, mortality and treatment costs. This study aimed to investigate the relationship between gaseous microemboli (GME) load during cardiopulmonary bypass (CPB) and subsequent POD in patients undergoing CABG. Methods: In total, 102 patients undergoing elective on-pump CABG were evaluated in this observational study. An ultrasonic microbubble counter, with probes placed on the arterial and venous lines, was used during CPB to evaluate the GME load for each patient. During the first postoperative week, the patients were examined for the presence of POD. Results: Patients diagnosed with POD had higher number of bubbles in the arterial CPB line (5382.8 (4127.8–6637.8) vs. 2389.4 (2033.9–2745.0), p < 0.001), higher volume of bubbles in both the venous (24.2 µL (16.8–31.6) vs. 12.4 µL (9.7–15.1), p = 0.004) and arterial lines (1.82 µL (1.43–2.21) vs. 0.29 µL (0.22–0.36), p < 0.001), lower quality factor (QF) values (p = 0.039), a lower venoarterial reduction in bubble number (83.0% (77.8–88.1) vs. 92.4% (90.9–93.8), p = 0.001) and a lower venoarterial reduction in bubble volume (88.8% (85.4–92.2) vs. 96.3% (95.2–97.3), p < 0.001) compared to the patients without POD. Older age (p = 0.005), a lower reduction in bubble volume (p < 0.001) and lower QF values (p = 0.004) were significant independent predictors of POD. Conclusions: Our findings indicate a strong association between GME and the occurrence of POD, which entails that all available actions should be implemented to prevent their generation and facilitate the elimination of GME from the CPB circuit.

Background: Digital technologies offer innovative opportunities for recovering and maintaining intellectual and mental health. The use of a multitask approach that combines motor component with various cognitive tasks in a virtual environment can optimize cognitive and physical functions and improve the quality of life of cardiac surgery patients. This study aimed to localize current sources of theta and alpha power in patients who have undergone virtual multitask training (VMT) and a control group in the early postoperative period of coronary artery bypass grafting (CABG). Methods: A total of 100 male CABG patients (mean age, 62.7 ± 7.62 years) were allocated to the VMT group (n = 50) or to the control group (n = 50). EEG was recorded in the eyes-closed resting state at baseline (2–3 days before CABG) and after VMT course or approximately 11–12 days after CABG (the control group). Power EEG analysis was conducted and frequency-domain standardized low-resolution tomography (sLORETA) was used to assess the effect of VMT on brain activity. Results: After VMT, patients demonstrated a significantly higher density of alpha-rhythm (7–9 Hz) current sources (t > −4.18; p < 0.026) in Brodmann area 30, parahippocampal, and limbic system structures compared to preoperative data. In contrast, the control group had a marked elevation in the density of theta-rhythm (3–5 Hz) current sources (t > −3.98; p < 0.017) in parieto-occipital areas in comparison to preoperative values. Conclusions: Virtual reality-based multitask training stimulated brain regions associated with spatial orientation and memory encoding. The findings of this study highlight the importance of neural mechanisms underlying the effectiveness of multitask interventions and will be useful for designing and conducting future studies involving VR multitask training.

Background/Objectives: Epicardial adipose tissue (EAT) is metabolically active and is in dynamic crosstalk with the surrounding cardiomyocytes, modulating their function and metabolism. Oxidative stress is a key contributor to cell death and cardiac remodeling, is a hallmark of diabetes (DM) and cardiovascular disease, such as coronary artery disease (CAD). However, little is known about these processes in EAT from patients undergoing cardiac surgery. This study investigates changes in mitochondrial dynamics, reactive oxygen species (ROS) production, and antioxidant defense levels in EAT compared to subcutaneous adipose tissue (SAT) in patients undergoing cardiac surgery, with a focus on the impact of DM and CAD. Methods: Adipose tissue biopsies were collected from 128 patients undergoing surgical cardiac intervention. Mitochondrial dynamics and oxidative stress markers were analyzed. Results: EAT exhibited increased expression of mitochondrial fusion markers [mitofusin 1 (p ≤ 0.001), mitofusin 2 (p = 0.038), and optic atrophy 1 (p ≤ 0.001)], as well as fission markers [fission 1 (p ≤ 0.001) and dynamin-related protein 1 (p ≤ 0.001)] relative to SAT. Additionally, ROS levels (dihydroethidium, p = 0.004) were elevated, while lipid peroxidation (malondialdehyde, p ≤ 0.001) was reduced in EAT compared to SAT. Reduced glutathione (GSH) levels (p ≤ 0.001) and the redox buffer ratio between reduced and oxidized glutathione (GSH/GSSG, p ≤ 0.001) were significantly increased in EAT. Interestingly, glutathione peroxidase activity (p ≤ 0.001) and the antioxidant defense markers catalase (p ≤ 0.001) and superoxide dismutase 2 (p = 0.001) were significantly reduced in EAT compared to SAT. Conclusions: The findings provide a unique molecular insight into the mitochondrial dynamics and oxidative stress profiles of EAT, highlighting potential avenues for a novel diagnostic method and therapeutic strategies for cardiac disease.

Purpose: We aimed to evaluate the safety and feasibility of a remote electrocardiogram (ECG) monitoring-based cardiac rehabilitation (CR) program during an early postoperative period in patients who underwent cardiac surgery. Methods: Five days after cardiac surgery, patients were referred to a CR department and participated in a low-intensity inpatient CR program while wearing an ECG monitoring device. Prior to discharge, the patients underwent a cardiopulmonary exercise test (CPET) and squat endurance test to determine the suitable intensity and target heart rate (HR) for home-based CR (HBCR). During 2 weeks of the HBCR period after discharge, patients participated in aerobic and resistance exercises. Electrocardiogram data were transmitted to a cloud, where researchers closely monitored them through a website and provided feedback to the patients via telephone calls. Grip strength (GS), 6 min walk distance (6 MWD), EuroQol-5 dimension (EQ-5D), short-form 36-item health survey (SF-36), and Korean Activity Scale/Index (KASI) were measured at three different time points: 5 d post-surgery (T1), pre-discharge (T2), and 2 weeks after discharge (T3). Squat endurance tests and CPET were performed only at T2 and T3. Result: Sixteen patients completed the study, seven (44%) of whom underwent coronary artery bypass graft surgery (CABG). During the study period between T2 and T3, peak VO₂ improved from 12.39 ± 0.57 to 17.93 ± 1.25 mL/kg/min (p < 0.01). The squat endurance test improved from 16.69 ± 2.31 to 21.81 ± 2.31 (p < 0.01). In a comparison of values of time points between T1 and T3, the GS improved from 28.30 ± 1.66 to 30.40 ± 1.70 kg (p = 0.02) and 6 MWD increased from 249.33 ± 20.92 to 387.02 ± 22.77 m (p < 0.01). The EQ-5D and SF-36 improved from 0.59 ± 0.03 to 0.82 ± 0.03 (p < 0.01) and from 83.99 ± 3.40 to 122.82 ± 6.06 (p < 0.01), and KASI improved from 5.44 ± 0.58 to 26.11 ± 2.70 (p < 0.01). In a subgroup analysis, the CABG group demonstrated a greater increase in 6 MWD (102.29 m, p < 0.01) than the non-CABG group. At the end of the study, 75% of the patients expressed satisfaction with the early CR program guided by remote ECG monitoring. Conclusions: Our findings suggest that early remote ECG monitoring-based CR programs are safe and feasible for patients who have undergone cardiac surgery. Additionally, the program improved aerobic capacity, functional status, and quality of life. Full article

Background: Coronary heart disease (CHD) remains the most prevalent pathology within the circulatory system. Among its chronic complications, ischemic mitral valve regurgitation (IMR) is observed in approximately 15% of patients with sustained myocardial ischemia. The presence of this complex valvular defect significantly increases both overall mortality and the incidence of adverse cardiovascular events. Notably, the presence of moderate to severe mitral regurgitation in patients undergoing surgical revascularization has been shown to double the risk of death. Despite the well-established etiology of IMR, data regarding the efficacy of surgical interventions and the determinants of postoperative outcomes remain inconclusive. Methods: The objective of the present study was to evaluate both early and long-term outcomes of surgical treatment of mitral regurgitation in patients undergoing coronary artery bypass grafting (CABG) due to ischemic heart disease. Particular attention was given to the influence of the severity of regurgitation, left ventricular ejection fraction (LVEF), and the dimensions of the left atrium (LA) and left ventricle (LV) on the postoperative prognosis. An additional aim was to identify preoperative risk factors associated with increased postoperative mortality and morbidity. A retrospective analysis was conducted on 421 patients diagnosed with ischemic mitral regurgitation who underwent concomitant mitral valve surgery and CABG. Exclusion criteria included emergent and urgent procedures as well as non-ischemic etiologies of mitral valve dysfunction. Results: The study cohort comprised 34.9% women and 65.1% men, with the mean age of 65.7 years (±7.57). A substantial proportion (76.7%) of patients were aged over 60 years. More than half (51.5%) presented with severe heart failure symptoms, classified as NYHA class III or IV, while over 70% were categorized as CCS class II or III. Among the surgical procedures performed, 344 patients underwent mitral valve repair, and 77 patients required mitral valve replacement. Additionally, 119 individuals underwent concomitant tricuspid valve repair. Short-term survival was significantly affected by the presence of hypertension, prior cerebrovascular events, and chronic kidney disease. In contrast, hypertension and chronic obstructive pulmonary disease were identified as significant predictors of adverse late-term outcomes. Conclusions: Interestingly, neither the preoperative severity of mitral regurgitation nor the echocardiographic measurements of LA and LV dimensions were found to significantly influence surgical outcomes. The perioperative risk, as assessed by the EuroSCORE II (average score: 10.0%), corresponded closely with observed mortality rates following mitral valve repair (9.9%) and replacement (10.4%). Notably, the need for concomitant tricuspid valve surgery was associated with an elevated mortality rate (12.4%). Furthermore, the preoperative echocardiographic evaluation of LA regurgitation severity, as well as LA and LV dimensions, did not exhibit a statistically significant impact on either early or long-term surgical outcomes. However, a reduced LVEF was correlated with increased long-term mortality. The presence of advanced clinical symptoms and the necessity for tricuspid valve repair were independently associated with a poorer late-term prognosis. Importantly, the annual mortality rate observed in the late-term follow-up of patients who underwent surgical treatment of ischemic mitral regurgitation was lower than rates reported in the literature for patients managed conservatively. The EuroSCORE II scale proved to be a reliable and precise tool in predicting surgical risk and outcomes in this patient population. Full article

Background/Objectives: Sternal pain after cardiac surgery results in considerable discomfort and may contribute to the development of chronic postoperative sternal pain syndrome. Parasternal intercostal plane blocks have been shown to improve postoperative sternal pain and can be an essential part of enhanced recovery after cardiac surgery (ERACS). This cohort study evaluated the postoperative impact of a single-shot deep parasternal intercostal plane block (PIPB) on the requirement of analgesic medication and pain sensation up to 48 h. Methods: This retrospective single-center analysis evaluates the postoperative acute pain in 157 patients undergoing off-pump coronary artery bypass (OPCAB) with median sternotomy. The additive analgesic effects of deep PIPB (38 patients) were compared to a group with standard therapy but without PIPB (119 patients). To strengthen the findings, a propensity score matching analysis was performed. Outcomes included the consumption of emergency pain agents (piritramide), the requirement of the total morphine equivalent (ME), time to extubation, and ICU length of stay. Furthermore, we examined pain sensation with evaluation by using the behavioral pain score (BPS) and numeric rating score (NRS) up to 48 h after extubation. Results: The deep PIPB reduced the piritramide administration 24 h and 48 h after OPCAB surgery. Moreover, the requirement of ME was 24 h and 48 h after bypass surgery also significantly decreased. The one-to-one propensity score matching confirmed our primary findings and showed a decreased requirement for intravenous agents. Additionally, we observed a reduced time for extubation and a decreased NRS rating. However, no significant changes were observed in ICU length of stay, incidence of nausea, and vomiting. Conclusions: Our data suggests that an ultrasound-guided single-shot deep PIPB can be a valuable tool for a multimodal analgesic protocol on patients undergoing OPCAB surgery. Full article

Background: Although contemporary stent technology has significantly evolved, a substantial number of patients present with stent failure (SF), the clinical expression of which is either in-stent restenosis (ISR) or stent thrombosis (ST). Methods: In this observational, single-center study, we aimed to compare the clinical characteristics, clinical presentation, angiographic findings and subsequent management of patients who underwent percutaneous coronary intervention (PCI) for SF, either ISR or ST, with patients who had PCI for de novo lesions. Results: Over a period of two years (September 2022–October 2024), 1120 patients underwent PCI, of whom 9% had SF. Of the 101 SF cases, the majority (76 cases, 75%) had ISR, while the rest (25 cases, 25%) had ST. Regarding baseline characteristics, patients who underwent PCI for SF had a higher incidence of diabetes mellitus (53% vs. 29%; p < 0.001), dyslipidemia (88% vs. 50%; p < 0.001) as well as prior coronary artery bypass grafting surgery (7.9% vs. 3.7%; p = 0.043), while they were less likely to be current smokers (33% vs. 52%; p < 0.001). SF PCI patients presented more frequently with unstable angina (17% vs. 8.9%; p = 0.010). A new stent was implanted in less than half of SF cases (i.e., stent implantation, 44% vs. 91%; p < 0.001). On the other hand, in the clinical setting of SF, drug-coated balloons (44% vs. 5.3%; p < 0.001) and plain balloon angioplasty (8.9% vs. 0.7%; p < 0.001) was applied more frequently compared with de novo lesions. Furthermore, the usage of cutting/scoring balloons and lithotripsy was significantly higher in the SF group (8.9% vs. 0.4% and 12% vs. 3%, respectively; p < 0.001 for both). Intracoronary imaging guidance was more commonly used in the SF group (33% vs. 13%; p < 0.001). Stent malapposition (44%) and neoatherosclerosis (67%) were the most common mechanisms of ST and ISR, respectively, as identified by intravascular imaging modalities. Finally, the success rates were comparable (96% vs. 98%; p = 0.150) between the two groups. Conclusions: Approximately one of ten patients underwent PCI because of the failure of a previously implanted stent. Use of intracoronary imaging is significantly higher in the clinical context of SF. While DES implantation remains the standard of practice for de novo lesions, DCBs are a popular alternative, especially for ISR cases. Interventional cardiologists who are involved in the treatment of SF cases should be familiar with interpreting intravascular imaging to guide the use of the adjunctive device required to ensure that optimal procedural results in SF cases are obtained.

Background: Obstructive sleep apnea (OSA) is a prevalent but frequently underdiagnosed comorbidity in patients undergoing cardiac surgery, including coronary artery bypass grafting (CABG), aortic valve replacement (AVR), and mitral valve repair or replacement (MVR). This systematic review and meta-analytic synthesis investigates the relationship between OSA and postoperative morbidity and mortality, with particular attention to the predictive utility of established screening instruments. Methods: A systematic search of the PubMed database was conducted (April 2025), identifying 724 articles published in the last ten years. Seventeen primary studies met the inclusion criteria for qualitative synthesis, and four additional studies were included in the meta-analyses. Outcomes assessed included atrial fibrillation, major adverse cardiac and cerebrovascular events (MACCE), acute kidney injury (AKI), respiratory complications, pneumonia, hospital length of stay (LOS), and mortality. Risk of bias was assessed qualitatively based on study design and reporting limitations. This review was registered in the PROSPERO database under registration number CRD420251049574. Results: Meta-analyses demonstrated significantly elevated odds of atrial fibrillation (OR = 2.44, 95% CI: 1.46–4.07), major adverse cardiac and cerebrovascular events (OR = 2.06, 95% CI: 1.61–2.63), acute kidney injury (OR = 2.24, 95% CI: 1.67–3.01), and respiratory complications (OR = 1.15, 95% CI: 1.05–1.25) among patients with OSA. Additionally, OSA was associated with a significantly prolonged hospital length of stay (standardized mean difference [SMD] = 0.62, 95% CI: 0.46–0.78) and a marginal increase in pneumonia risk (OR = 1.07, 95% CI: 1.00–1.15). Evidence regarding stroke, intensive care unit (ICU) stay, and mortality was inconsistent or underpowered. Conclusions: Across core outcomes, findings were consistent across multiple studies involving a large patient population. Obstructive sleep apnea is a clinically consequential risk factor in cardiac surgery, associated with increased perioperative complications and prolonged hospitalization. These findings support the integration of routine OSA screening into preoperative risk assessment protocols. Further prospective, multicenter trials are warranted to assess the efficacy of perioperative management strategies, including continuous positive airway pressure (CPAP) therapy, in improving surgical outcomes.

Background: Patients diagnosed with coronary artery disease (CAD) have been seen to exhibit increases in health-related quality of life (HRQoL) following percutaneous coronary interventions (PCIs). This study thus aimed to assess the impact of PCI on health outcomes among Jordanian patients three months post-procedure. Methods: This prospective descriptive study evaluated health outcomes three months post-PCI among Jordanian patients who had been originally diagnosed with Chronic Coronary Syndrome (CCS) before being scheduled for PCIs. Quantitative data was collected using the updated version of the Coronary Revascularization Outcome Questionnaire (CROQ v2) across a non-probability sample, based on accessibility, of Jordanian patients who had received the procedure at any of several hospitals in Jordan. Multivariate analysis of covariance (MANCOVA) was employed to examine the mean scores of patient-reported outcomes following revascularization, while partial correlations were employed to investigate associations among patients’ age, weight, gender, and the reported results. Results: A total of 101 patients participated in the study, with a predominance of males (n = 85, 84.2%) relative to females (n = 16, 15.8%). The results indicated a statistically significant improvement across all measures assessed across these patients. Furthermore, the results demonstrated that males showed higher physical function, psychological functioning, and cognitive performance relative to females following coronary revascularization surgery. Nevertheless, the results also revealed varied levels of adverse effects following coronary revascularization, with the most commonly reported being discomfort around the groin or arm wound, followed by pain in the same areas. Conversely, the least significant concerns pertained to the emergence of bruises and similar issues in the groin or arm areas where the catheter was inserted. Conclusions: This study shows that PCI improves CAD patients’ quality of life over the initial three-month period post-procedure. Understanding the positive associations of this and the negative consequences that it entails may help healthcare practitioners better identify those patients likely to benefit or suffer from PCI, enabling more appropriate interventions. To understand how PCI affects HRQoL in CAD patients over time, more research based on rigorous study designs and validated metrics is required, however. Full article

This article reveals the various types of complications that are associated with dialysis and kidney-associated disease, including left ventricular hypertrophy, heart failure, vascular heart disease, arrhythmias, diabetes mellitus, intradialytic hypertension, and coronary heart disease. The molecular mechanisms underlying the development of cardiovascular disease in patients with chronic kidney disease (CKD), including the role of nitric oxide (NO) signaling, have been extensively studied. Patients suffering from CKD need treatment with hemodialysis at the end stages. The kidney is considered the chief excretory organ in humans, which excretes various types of waste materials from the body and balances the acid–base ratio, due to which its role in homeostasis has been considered. When kidneys fail to function properly due to various diseases, hemodialysis plays the role of the kidneys. This procedure involves removing a patient’s blood, filtering it through a dialyzer to remove waste products, and returning the cleaned blood to the body. However, for the hemodialysis procedure, fistula formation is necessary, which is created by specific surgery in which the radial artery and superficial vein are connected in the forearm, near the wrist or elbow. This arteriovenous (AV) fistula creation fails sometimes and causes complications. The prolonged use of hemodialysis procedures and improper care also lead to many complications in chronic kidney patients, which have been discussed in detail in this review article. Full article

Background: Patients who undergo cardiac surgery and procedures often experience functional impairments. However, few studies have compared changes in physical function, cognitive function, mental health, and sleep quality before and after the interventions. Methods: Intensive care unit (ICU) nurses visited the ward and conducted the assessments. The Japanese version of the Cardiovascular Health Study (J-CHS) and the Barthel index for physical function, mini-mental state examination (MMSE) for cognitive function, hospital anxiety and depression scale for anxiety (HADS-A) and depression (HADS-D) for mental health, and a 5-point Likert scale for sleep quality were used. Results: Of the 210 cases, 156 were included. Cardiac surgeries and procedures included valve replacement or valvuloplasty (43%), coronary artery bypass graft (9%), and transcatheter aortic valve implantation (39%). At a median of 7 (4–9) days after ICU discharge, the J-CHS score worsened from 2 (1–3) to 3 (2–3) (p < 0.01), and the Barthel index worsened from 95 (85–100) to 75 (55–85) (p < 0.01). The HADS-A score improved from 3 (1–6) to 1 (0–4) (p < 0.01), and the HADS-D score improved from 4 (1–7) to 2 (1–6) (p < 0.01). The MMSE score remained unchanged at 26 (24–29; p = 0.91). Sleep quality worsened from 4 (3–5) to 3 (2–4) (p < 0.01). In the multivariate analysis, sleep quality deterioration was associated with open thoracotomy. Conclusions: After cardiac surgeries and procedures, physical function and sleep quality worsened, whereas anxiety and depression improved, and cognitive function remained unchanged. Full article

Background/Objectives: After years of work in the field of aortic arch surgery, the technique has evolved, making this procedure relatively safe, with lasting results. Due to the increasing long-term survival and overall aging of the patient population, more patients require aortic arch reoperation. In the present study, the safety of aortic arch reoperations was analyzed in the long term, focusing on risk factors for mortality. Methods: Between 1999 and 2023, 108 patients were included in our study who underwent reoperation on aortic arch after prior operation on the aorta, the aortic valve, or a combination of both. The exclusion criteria were being aged under 18 years and transcatheter aortic valve implantation as a previous intervention. The principal outcome was the incidence of mortality, and additional outcomes of interest included cardiac re-reoperation, bleeding, a new aortic type B dissection, infective endocarditis, readmission due to a cardiac cause, coronary intervention and neurovascular complications, pacemaker implantation, and temporary mechanical circulatory support. Results: The mean age was 56 ± 14 years, and 75% (81/108) of patients were male. In our study, we found age (p ≤ 0.01) and history of coronary artery disease (p = 0.01) to be preoperative risk factors for adverse outcomes. The mean time between the index operation and reoperation was 6.84 years (1.61–14.94). Indications for reoperation included dilatation (HR = 0.49, p = 0.05), rupture or false aneurysm (HR = 2.08, p= 0.08), dissection (HR = 1.41, p = 0.30), and endocarditis (HR = 1.49, p = 0.41). A main risk factor was the need for a salvage reoperation (p ≤ 0.01). Also, a longer operation (p = 0.04), cardiopulmonary bypass (p ≤ 0.01), and ventilation time (p ≤ 0.01), bleeding complications (p ≤ 0.01), and requiring temporary mechanical circulatory support (p = 0.04) were linked to higher mortality. The overall survival was 82% after 1 year, 73% after 5 years, and 56% after 10 years. In the multivariate Cox regression analysis, age (HR = 1.04, p ≤ 0.01), the need for a salvage operation (HR = 5.38, p = 0.01), a prolonged ventilation time (HR = 1.08, p = 0.04), and bleeding complications (HR = 3.76, p = 0.03) were associated with higher mortality. In the ROC analysis, an age over 57.5 years was associated with significantly lower overall survival (p ≤ 0.01). Conclusions: Aortic arch reoperations can be performed with acceptable long-term outcomes, but perioperative factors significantly influence early mortality. Salvage operations, bleeding complications, and prolonged ventilation were strong predictors of adverse outcomes. Older age, particularly >57.5 years, was independently associated with increased mortality risk. Full article
