Impact of Smoking on All-Cause Mortality in Patient Undergoing Cardiovascular and Thoracic Procedures: A Prospective Observational Study

Introduction: Tobacco smoke is the primary cause of illness and death in today's society, and cigarette smoking (CS) remains a substantial health risk. The primary goal of this study was to assess the extent of smoking among adult Kashmiri patients who had undergone cardiovascular procedures and to identify the sociodemographic factors associated with smoking in this population. Methods: A prospective evaluation was conducted on 143 patients who underwent various thoracic and cardio-vascular procedures. With the use of a common, validated questionnaire, data was collected. The investigation utilized Cox proportional hazards regression to explore the associations between smoking and overall mortality, incorporating adjustments for non-communicable diseases, sociodemographic factors, and lifestyle variables. Results: In total, 36.92% (95% CI: 1.54%–1.71%) of people were smokers, with men having a considerably greater prevalence than women (85.42%, 95% CI: 0.75–0.95 vs. 14.58%, 95% CI: 0.08–0.4). The age group of 33–63 years old had the highest rate of smoking prevalence (77.08%). Additionally, the multivariate logistic regression showed that men were substantially more likely than women to smoke (aOR 0.39, 95%CI: 0.28-0.21). A higher odds ratio indicates high cause of smoking. Conclusions: The chance of mortality from daily smoking increased as the intensity of smoking increased. Consequently, persistent tobacco use is linked to a notably increased likelihood of mortality from any cause. Tobacco smoking necessitates a long-term plan of care. It should be treated with the same rigor as other health risks.

Effectiveness of intraoperative nerve monitoring in reducing rates of recurrent laryngeal nerve injury in aerodigestive and cardiovascular pediatric surgery

ObjectiveTo investigate the effectiveness of intraoperative nerve monitoring at decreasing vocal fold movement impairment in children undergoing at-risk procedures. BackgroundChildren undergoing aerodigestive or cardiovascular procedures are at risk for recurrent laryngeal nerve injury, leading to vocal fold movement impairment. Although intraoperative nerve monitoring has been shown to decrease recurrent laryngeal nerve injury in adults, there is paucity of data in children. MethodsThis was a retrospective, single-center cohort study of children who underwent airway, esophageal, or great vessel surgery between 2018 and 2023. Vocal fold movement impairment was evaluated with pre- and postoperative awake flexible fiberoptic laryngoscopy. Vocal fold movement impairment rates and associated characteristics were compared between those with and without intraoperative nerve monitoring. ResultsAmong 387 children undergoing 426 at-risk procedures, intraoperative nerve monitoring was used in 72.1% (n = 307) of procedures. Intraoperative nerve monitoring significantly reduced postoperative vocal fold movement impairment compared with those without (11.4% vs 20.2%, P = .019, 43.6% relative risk reduction, number needed to treat: 12). In children with a pre-existing vocal fold movement impairment (n = 79, 18.5%), intraoperative nerve monitoring provided enhanced protection (vocal fold movement impairment 7.8% with intraoperative nerve monitoring compared with 25% without, P = .046, 68.6% relative risk reduction, number needed to treat: 3). Bilateral vocal fold movement impairment was 14 times more likely without intraoperative nerve monitoring (1.8% overall, 0.3% with intraoperative nerve monitoring, 5.6% without; 95% confidence interval 1.6–123.2; P = .006). Increasing intraoperative nerve monitoring use correlated with decreasing vocal fold movement impairment rates year over year (P = .046). Multivariable logistic regression demonstrated intraoperative nerve monitoring to remain significantly associated with reduced risk of vocal fold movement impairment (odds ratio, 0.48; 95% confidence interval, 0.26–0.85; P = .013). ConclusionIntraoperative nerve monitoring in children seems effective at decreasing recurrent laryngeal nerve injury and consequently vocal fold movement impairment. Intraoperative nerve monitoring should be considered in children undergoing cervicothoracic or cardiothoracic procedures, especially in those with preoperative vocal fold movement impairment.

Clinical Outcome of Surgical Treatment of Giant Femoral Artery Pseudoaneurysms

Femoral artery was used as an access site for cardiovascular procedures and by IV drug abusers, Femoral Artery Pseudoaneurysm (FAP) was a common complication associated with these procedures. Objective: To evaluate clinical outcome of surgical repair of femoral artery pseudoaneurysms. Methods: The prospective study was conducted in Doctors Hospital, Lahore from October 2022 to October 2023. The study included patients with giant femoral artery pseudoaneurysms who required surgical intervention. Data from a total of 50 patients were included in whom both peripheral vascular interventions and percutaneous cardiac catheterization was performed. Patients were followed up at 1-, 3-, 6- and 12 months postoperatively. SPSS version 23.0 was used for data analysis. Results: All patients underwent open surgical treatment. Of 50 patients, 25 (50%) had SFA pseudoaneurysm, 20 (40%) had CFA pseudoaneurysm and 5 (10%) had PFA pseudoaneurysm. The mean duration of clinical manifestations was 16.30 ± 7.74 days. Surgical repair was successful in all 50 (100%) patients and distal ischemia was fully resolved. There was no case of limb loss or post-operative mortality. One patient had an infection in the groin wound and had raised Total leucocyte count (TLC), which was resolved by early drainage and antibiotic treatment. Patients were followed up at 1, 3, 6, and 12 months and there were no signs of clinical or angiographic evidence of post-operative complications and changes in distal pulse. Conclusion: Surgical repair was first-line treatment for giant FAP. It was clinically feasible and has a high success rate and low complication rate.

A Novel Suture-Based Vascular Closure Device to Achieve Hemostasis after Venous or Arterial Access While Leaving Nothing behind: A Review of the Technological Assessment and Early Clinical Outcomes.

Vascular hemostasis after venous and arterial access in cardiovascular procedures remains a challenge. As sheath size gets larger for structural heart and vascular procedures, no dedicated closure devices exist that can overcome all the challenges of achieving vascular hemostasis, in particular on the venous side. Efficiently and reliably ensuring hemostasis at the access point is crucial for enhancing the safety of a procedure. Historically, hemostasis relied on manually compressing venous access sites. However, the shift towards larger sheaths and the more frequent use of continuous anticoagulation has strained this approach. Achieving hemostasis solely through compression in these scenarios demands heightened vigilance and prolonged application, resulting in increased patient discomfort and extended immobility. Consequently, manual compression may consume more time for healthcare providers and contribute to bed occupancy in hospitals. This review article summarizes the development of the SiteSeal® Vascular Closure Device, a novel leave-nothing-behind approach to achieve hemostasis. The introduction of this technology has provided clinicians with a safer and more effective way to achieve immediate hemostasis, facilitate early ambulation, and enable earlier discharges with fewer access site complications compared with traditional manual compression.

Effect of bivalirudin on myocardial microcirculation and adverse events after interventional therapy in older patients with acute coronary syndrome.

Bivalirudin, a direct thrombin inhibitor, is used in anticoagulation therapies as a substitute for heparin, especially during cardiovascular procedures such as percutaneous coronary intervention. To explore the effect of bivalirudin on myocardial microcirculation following an intervention and its influence on adverse cardiac events in elderly patients with acute coronary syndrome (ACS). In total, 165 patients diagnosed with acute myocardial at our hospital between June 2020 and June 2022 were enrolled in this study. From June 2020 to June 2022, elderly patients with ACS with complete data were selected and treated with interventional therapy. The study cohort was randomly divided into a study group (n = 80, administered bivalirudin) and a control group (n = 85, administered unfractionated heparin). Over a 6-mo follow-up period, differences in emergency processing times, including coronary intervention, cardiac function indicators, occurrence of cardiovascular events, and recurrence rates, were analyzed. Significant differences were observed between the study cohorts, with the observation group showing shorter emergency process times across all stages: Emergency classification; diagnostic testing; implementation of coronary intervention; and conclusion of emergency treatment (P < 0.05). Furthermore, the left ventricular ejection fraction in the observation group was significantly higher (P < 0.05), and the creatine kinase-MB and New York Heart Association scores were notably lower than those in the control group (P < 0.05). In elderly patients receiving interventional therapy for ACS, bivalirudin administration led to increased activated clotting time achievement rates, enhanced myocardial reperfusion, and reduced incidence of bleeding complications and adverse cardiac events.

Incidence of Acute Kidney Injury and Mortality Post Successful Cardiac Surgery in a Kashmiri Cohort: A Prospective Comparison of the RIFLE and KDIGO Criteria.

Background and objectives In critically ill patients, acute kidney injury (AKI) influences mortality and morbidity. Few studies have looked at mortality and the frequency of AKI following successful heart and thoracic operations. The current study investigates the association between AKI and mortality rates among patients undergoing post-cardiac surgery care within the Cardiology & Cardio Vascular Thoracic Surgery (CVTS) Intensive Care Unit (ICU). Methodology In this prospective research, 124 patients who underwent successful cardiovascular and thoracic procedures between June 2022 and June 2023 were admitted to the CVTS ICU. To determine mortality, we contrasted the two scoring methods, Kidney Disease-Improving Global Outcomes (KDIGO) and Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE). Results Based on the KDIGO criteria, AKI was identified in 37.90% (n = 47) of the patients, and it was identified in 15.32% (n = 19) of the patients utilizing RIFLE. Notably, patients diagnosed with AKI using either the RIFLE criteria or KDIGO criteria exhibited considerably higher mortality rates (p< 0.001). Receiver operating characteristic (ROC) analysis demonstrated the effectiveness of both scoring systems in identifying mortality (area under the ROC curve for RIFLE = 0.224 and KDIGO = 0.150). Conclusion Post-cardiac surgery, AKI escalates both mortality and morbidity rates. Despite KDIGO detecting more severe renal injury and mortality, both scoring systems exhibit comparable sensitivity and specificity in predicting death among patients undergoing various cardiovascular and thoracic procedures.

Relationship between indexed surgery and postcardiotomy extracorporeal life support outcomes.

Veno-arterial extracorporeal life support (V-A ECLS) is increasingly being utilized for postcardiotomy shock (PCS), though data describing the relationship between type of indexed operation and outcomes are limited. This study compared V-A ECLS outcomes across four major cardiovascular surgical procedures. This was a single-center retrospective study of patients who required V-A ECLS for PCS between 2015 and 2022. Patients were stratified by the type of indexed operation, which included aortic surgery (AoS), coronary artery bypass grafting (CABG), valve surgery (Valve), and combined CABG and valve surgery (CABG + Valve). Factors associated with postoperative outcomes were assessed using logistic regression. Among 149 PCS patients who received V-A ECLS, there were 35 AoS patients (23.5%), 29 (19.5%) CABG patients, 59 (39.6%) Valve patients, and 26 (17.4%) CABG + Valve patients. Cardiopulmonary bypass times were longest in the AoS group (p < 0.01). Regarding causes of PCS, AoS patients had a greater incidence of ventricular failure, while the CABG group had a higher incidence of ventricular arrhythmia (p = 0.04). Left ventricular venting was most frequently utilized in the Valve group (p = 0.07). In-hospital mortality was worst among CABG + Valve patients (p < 0.01), and the incidence of acute kidney injury was highest in the AoS group (p = 0.03). In multivariable logistic regression, CABG + Valve surgery (odds ratio (OR) 4.20, 95% confidence interval 1.30-13.6, p = 0.02) and lactate level at ECLS initiation (OR, 1.17; 95% CI, 1.06-1.29; p < 0.01) were independently associated with mortality. We demonstrate that indications, management, and outcomes of V-A ECLS for PCS vary by type of indexed cardiovascular surgery.

Assessment of Upper Limb Nerves in Coronary Artery Disease Patients Undergoing Coronary Artery Bypass Graft.

Background Many patients experience pain in their upper limbs following surgical procedures involving median sternotomy, particularly those undergoing coronary artery bypass grafting (CABG). This type of pain, commonly reported by CABG patients, is often overlooked in hospital settings. Our study aims to address this issue by utilizing electrodiagnostic studies to understand this postoperative discomfort better. Objectives Cardiovascular procedures are standard and are trending toward endovascular interventions. Through this study, we aim to assess the occurrence of neurological issues in the upper limbs after CABGby comparing patients' preoperative and postoperative electrophysiological studies of the upper limb nerves. Materials and methods A prospective study was performed on 32 coronary artery disease (CAD) patients undergoing CABG to determine the effects of surgery on the upper limb nerves (median and ulnar nerves). We performed nerve conduction studies (NCS) and analyzed different parameters of both median and ulnar nerves pre and post-surgery. Results A change was noted in different NCS parameters of the median and ulnar nerves when we comparedthe pre and post-surgical values. The meanlatency of the median nerve sensory increased from a minimum of 3.01 millisecondsat the preoperative level to a maximum of 3.60 milliseconds when assessedtwo weeks post-surgery. The mean amplitude decreased from 16.49 microvolts to a minimum of 12.30 microvolts when assessed two weeks post-surgery. The meanvelocity decreased from 55.83 m/s at the preoperative value to a minimum of 45.03 m/sat the two weeks post-surgery assessment. The ulnar nerve also underwent similar changes. Conclusion The observed changes in latency, amplitude, and velocity might be attributed to various factors, including surgical trauma, inflammation, or alterations in the physiological state post-surgery. The sternotomy technique and the position and extent of opening the sternal retractor determine the prevalence of complications by causing injury to the medial and lateral cords of the brachial plexusafter CABG. Careful preoperative and postoperative assessments of patients may aid in preventing, minimizing, and treating these often undiagnosed complications.

Optimization of Hypothermic Protocols for Neurocognitive Preservation in Aortic Arch Surgery: A Literature Review.

Shifts from deep to moderate hypothermic circulatory arrest (HCA) in aortic arch surgery necessitate an examination of their differential impacts on neurocognitive functions, especially structured verbal memory, given its significance for patient recovery and quality of life. This study evaluates and synthesizes evidence on the effects of deep (≤20.0 °C), low-moderate (20.1-24.0 °C), and high-moderate (24.1-28.0 °C) hypothermic temperatures on structured verbal memory preservation and overall cognitive health in patients undergoing aortic arch surgery. We evaluated the latest literature from major medical databases such as PubMed and Scopus, focusing on research from 2020 to 2024, to gather comprehensive insights into the current landscape of temperature management during HCA. This comparative analysis highlights the viability of moderate hypothermia (20.1-28.0 °C), supported by recent trials and observational studies, as a method to achieve comparable neuroprotection with fewer complications than traditional deep hypothermia. Notably, low-moderate and high-moderate temperatures have been shown to support substantial survival rates, with impacts on structured verbal memory preservation that necessitate careful selection based on individual surgical risks and patient profiles. The findings advocate for a nuanced approach to selecting hypothermic protocols in aortic arch surgeries, emphasizing the importance of tailoring temperature management to optimize neurocognitive outcomes and patient recovery. This study fills a critical gap in the literature by providing evidence-based recommendations for temperature ranges during HCA, calling for ongoing updates to clinical guidelines and further research to refine these recommendations. The implications of temperature on survival rates, complications, and success rates underpin the necessity for evolving cardiopulmonary bypass techniques and cerebral perfusion strategies to enhance patient outcomes in complex cardiovascular procedures.

Radiation Exposure During Invasive Cardiovascular Procedures: Portable Shielding System Versus Standard Lead Aprons.

Introduction Significant progress in the field of interventional cardiology has led to a rise in percutaneous procedures and an increase in the risk of radiation exposure at the workplace. Staff health has been put at risk due to the limitations of conventional radiation protective techniques. Innovative methods, such as RAMPART, have promising prospects for enhancing radiation safety. The purpose of this study was to evaluate RAMPART's effectiveness and practicality in comparison to conventional protective techniques with a lead apron and shield (LAS) during cardiac interventional procedures. Method One hundred elective cardiac procedures were enrolled in this prospective single-center research study. Two groups were formed from the participants: standard protection (group A) and RAMPAT system (group B). Real-time dosimeters were used to track the radiation dosage, dosage reduction factor, dosage reduction percentage, and likelihood of exceeding the limit, which were included in the data. Proceduralists were urged to use different strategies to reduce exposure. The study was approved by an ethical committee and ran from June 2023 to August 2023. Results When comparing the RAMPART group to the conventional protection group, neck-level radiation exposure was considerably lower for all workers. There were no notable variations in the exposure of the waist. The RAMPART group was shown to be superior in minimizing radiation exposure, as evidenced by dose reduction metrics. The groups had comparable procedural characteristics. Conclusion Compared to conventional LAS, the RAMPART system dramatically reduces radiation exposure to the entire body.

Background, establishment and initial experiences of the Danish cardiovascular homograft biobank

Odense University Hospital is a major tertiary vascular hospital in Scandinavia, performing approx. 200 aortic repairs annually. This article presents the rationale behind this endeavor and the early outcomes of the initial implantation of locally processed homografts. All patients receiving a homograft were identified from the established homograft biobank database and their medical records were reviewed after obtaining consent. All surgeons in charge of homograft implantations were semi structured interviewed regarding the harvesting procedure, the tools for detecting available homografts, their quality and delivery. The National board of Health approved the biobank fulling the EU Directive of Tissues and Cells after 18 months of preparation. From May 6, 2021, to March 1, 2023, 26 patients had a homograft implantation, with 7 for mycotic aneurysms, 10 for aorto-iliac graft infection, 6 for infra-inguinal graft infection, and 3 for graft infection in thoracic aorta. Six (23%) were emergently performed. Two (7.7%) died within 30 days postoperatively, both following in situ replacement of an infected aortoiliac graft, corresponding to a 20% mortality in this subgroup. The incidence of reinfections was 19.2%; one each in the mycotic aneurysm group, the aortoiliac graft infection group, and the thoracic graft infection group. After 90 days, two patients were diagnosed with aorto-enteric fistula. All involved surgeons could easily identify available suitable homografts, and within 2 h have homografts of acceptable quality and requested dimensions. The establishment of the Danish Cardiovascular Homograft Biobank was straightforward and effectively serves cardiovascular procedures performed 24/7. Additionally, the initial experiences seem comparable to others experiences.

Peripheral artery disease is an independent risk factor for higher in-hospital mortality in Stanford type A aortic dissection repair.

Type A aortic dissection (TAAD) is an emergent condition that warrants immediate intervention. Peripheral artery disease (PAD) is a prevalent disease associated with worse outcomes in various cardiovascular procedures. However, it remains unclear whether PAD influences outcomes of TAAD repair. This study aimed to undertake a population-based analysis to assess impact of PAD on in-hospital outcomes following TAAD repair. Patients underwent TAAD repair were identified in National Inpatient Sample from Q4 2015 to 2020. Multivariable logistic regressions were used to compare in-hospital outcomes between patients with and without PAD, adjusted for demographics, socioeconomic status, primary payer status, hospital characteristics, comorbidities, and transfer/admission status. 1525 patients with PAD and 2757 non-PAD patients underwent TAAD. PAD patients had higher mortality (18.62% vs 13.17%, aOR = 1.287, p = .01), AKI (51.41% vs 47.48%, aOR = 1.222, p < .01), infection (10.69% vs 8.02%, aOR = 1.269, p = .03), and vascular complication (7.28% vs 3.77%, aOR = 1.846, p < .01) but lower risks of pericardial complications (15.21% vs 19.95%, aOR = 0.696, p < .01). In addition, patients with PAD had longer time from admission to operation (1.29 ± 3.95 vs 0.70 ± 2.09 days, p < .01), longer LOS (14.92 ± 13.98 vs 13.41 ± 11.66 days, p = .01), and higher hospital charge (499,064 ± 519,405 vs 409,754 ± 405,663 US dollars, p < .01). PAD was independently associated with worse outcome after TAAD repair. The elevated mortality rate could be attributed to the delay in surgery, which may be related to preoperative peripheral malperfusion syndrome that is common in PAD patients. A balance between preoperative management and immediate TAAD repair might be essential to prevent the increased mortality risk from treatment delays among PAD patients.

Association between Pan-Immune-Inflammation Value and Contrast-Induced Nephropathy with Coronary Angiography.

Background: Contrast-induced nephropathy (CIN) is one of the most important complications after invasive cardiovascular procedures. Considering the pivotal role of inflammation in CIN development, the use of peripheral blood-based indexes may be an easily available biomarker to predict CIN risk. Therefore, in the present study, we evaluated the association between the pan-immune-inflammation value (PIV) and the risk of CIN. Patients and Methods: A total of 1343 patients undergoing coronary angiography (CAG) were included. The PIV was calculated with the following equation: (neutrophil count × platelet count × monocyte count)/lymphocyte count. Multivariable regression analyses were used to determine the association between clinical and laboratory parameters and CIN development. Results: The median age of the cohort was 58 (IQR 50-67), and 48.2% of the patients were female. CIN developed in 202 patients (15%) in follow-up. In multivariate analyses, older age (OR: 1.015, 95% CI: 1.002-1.028, p = 0.020) and higher PIV levels (OR: 1.016, 95% CI: 1.004-1.028, p = 0.008) were associated with a higher CIN risk, while the use of antiplatelet agents was associated with a lower risk of CIN (OR: 0.670, 95% CI: 0.475-0.945, p = 0.022). Conclusions: We demonstrated that the risk of CIN was significantly higher in patients with higher PIV and older patients in a large cohort of patients undergoing CAG for stable ischemic heart disease. If supported with prospective evidence, PIV levels could be used as a minimally invasive reflector of CIN.

Magnesium sulfate for postoperative pain in orthopedic surgery: A narrative review.

Magnesium Sulfate (MgSO4) is a widely used adjuvant in anesthesia. Often administered with local anesthetics, it is known to reduce analgesic and opioid consumption while extending the duration of analgesia. MgSO4 applications extend to orthopedic surgeries, cardiovascular and urogenital procedures, offering extended postoperative pain relief. While commonly administered through various routes, there is a research gap concerning the comparative efficacy of intrathecal (IT) and intravenous (IV) MgSO4 administration. This narrative review aims to provide a comparison between IT and IV administration of MgSO4 particularly following orthopedic procedures, where pain management is paramount. A comprehensive literature search was conducted across several electronic databases, trial registries, and gray literature from inception to 2023. Inclusion criteria encompassed studies investigating the effects of perioperative IT administration of magnesium compared to perioperative IV administration of MgSO4 in patients undergoing surgery, with no language restrictions. Our search identified 4326 articles, of which 9 randomized controlled trials met our inclusion criteria. We summarized these selected articles. Four studies discussed IT magnesium sulfate (MgSO4) administration, 2 focused on IT administration in orthopedic surgeries, and 3 explored both IV and IT administration of MgSO4 in orthopedic surgery. IT MgSO4 shows promise in postoperative pain management, delaying block onset and extending duration. Personalized administration choice, considering patient factors and surgery type, is crucial. Further research is needed to refine strategies for better patient outcomes, particularly following orthopedic surgeries.

Procedure Volume and Outcomes With WATCHMAN Left Atrial Appendage Occlusion.

Procedure volumes are associated with outcomes for many cardiovascular procedures, leading to guidelines on minimum volume thresholds for certain procedures; however, the volume-outcome relationship with left atrial appendage occlusion is poorly understood. As such, we sought to determine the relationship between hospital and physician volume and WATCHMAN left atrial appendage occlusion procedural success overall and with the new generation WATCHMAN FLX device. We performed an analysis of WATCHMAN procedures (January 2019 to October 2021) from the National Cardiovascular Data Registry LAAO Registry. Three-level hierarchical generalized linear models were used to assess the adjusted relationship between procedure volume and procedural success (device released with peridevice leak <5 mm, no in-hospital major adverse events). Among 87 480 patients (76.2±8.0 years; 58.8% men; mean CHA2DS2-VASc score, 4.8±1.5) from 693 hospitals, the procedural success rate was 94.2%. With hospital volume Q4 (greatest volume) as the reference, the likelihood of procedural success was significantly less among Q1 (odds ratio [OR], 0.66 [CI, 0.57-0.77]) and Q2 (OR, 0.78 [CI, 0.69-0.90]) but not Q3 (OR, 0.95 [CI, 0.84-1.07]). With physician volume Q4 (greatest volume) as the reference, the likelihood of procedural success was significantly less among Q1 (OR, 0.72 [CI, 0.63-0.82]), Q2 (OR, 0.79 [CI, 0.71-0.89]), and Q3 (OR, 0.88 [CI, 0.79-0.97]). Among WATCHMAN FLX procedures, there was attenuation of the volume-outcome relationships, with statistically significant but modest absolute differences of only ≈1% across volume quartiles. In this contemporary national analysis, greater hospital and physician WATCHMAN volumes were associated with increased procedure success. The WATCHMAN FLX transition was associated with increased procedural success and less heterogeneity in outcomes across volume quartiles. These findings indicate the importance of understanding the volume-outcome relationship for individual left atrial appendage occlusion devices.

Out-of-Pocket Expenditure for Selected Surgeries in the Cardiology Department for Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY), Private Health Insurance, and Uninsured Patients in a Tertiary Care Teaching Hospital in Karnataka, India.

Cardiovascular diseases are a major public health issue and the leading cause of mortality globally. The global economic burden of out-of-pocket expenditure (OOPE) for cardiovascular surgeries and procedures is substantial, with average costs being significantly higher than other treatments. This imposes a heavy economic burden. Government insurance schemes like Ayushman Bharat Pradhan Mantri Jan Arogya Yojana (AB-PMJAY) aim to enhance affordability and access to cardiac care. This retrospective study analyzed OOPE incurred for top cardiac surgeries under AB-PMJAY, private insurance, and uninsured patients at a tertiary care teaching hospital in Karnataka. Data of 1021 patients undergoing common cardiac procedures from January to July 2023 were analyzed using descriptive statistics (mean, median) and the Shapiro-Wilk test for normality. The study aims to evaluate financial risk protection offered by AB-PMJAY compared to private plans and inform effective policy-making in reducing the OOPE burden for surgeries in India. The study analyzed OOPE across 1021 patients undergoing any of four surgeries at a tertiary care teaching hospital in Karnataka. AB-PMJAY patients incurred zero OOPE across all surgeries. Uninsured patients faced the highest median OOPE, ranging from ₹1,15,292 (1390.57 USD) to ₹1,72,490 (2080.45 USD) depending on surgery type. Despite the presence of private insurance, the median out-of-pocket expenditure ranged from ₹1,689 (20.38 USD) to ₹68,788 (829.67 USD). Significant variations in OOPE were observed within different payment groups. Private insurance in comparison with AB-PMJAY had limitations like co-payments, deductibles, and limited coverage resulting in higher OOPE for patients. The results illustrate the efficacy of AB-PMJAY in reducing the financial burden and improving the affordability of cardiac procedures compared to private insurance. This emphasizes the significance of programmmes funded by the government in reducing the OOPE burden and ensuring equitable healthcare access. The comprehensive and particular estimates of OOPE for different surgical procedures, categorized by payment methods provide valuable information to guide the development of policies that aim to reduce OOPE and progress towarduniversal health coverage in India.

A 25-year-long journey into interventional cardiology: looking back, and rushing forward.

Cardiovascular disease remains decade after decade a leading cause of mortality, morbidity and resource use globally as well as locally. We have had the opportunity of being involved in several iterative breakthroughs in invasive cardiovascular procedures, ranging from the advent of coronary stents to transcatheter mitral valve repair. Building up such extensive clinical and research experience, we hereby present 25 years of cardiovascular interventions at Pineta Grande Hospital and Casa di Salute S. Lucia, respectively in Castel Volturno, and S. Giuseppe Vesuviano, both in the Italian Campania region, where the same team of interventional cardiologists has managed to adopt and master several cardiovascular innovations for the benefit of thousands of patients. Our experience showcases the evolution of invasive cardiology, especially in diagnostic and therapeutic practices. Key highlights include advancements in coronary procedures, with the introduction of bare-metal stents, drug-eluting stents and drug-coated balloons, despite the setback of bioresorbable vascular scaffolds, as well as transcatheter aortic valve implantation and innovative approaches to mitral regurgitation. Furthermore, this overview scrutinizes procedural challenges, patient outcomes, and quality of life improvements, providing a rich tapestry of clinical experiences and research insights. It serves as a testament to the dynamic nature of interventional cardiology, offering a forward-looking perspective on future trends and technologies. We hope that this overview will prove an informative and insightful read for those seeking to understand the intricate journey of invasive cardiovascular care over the past decades and its trajectory into the future.

Trends in Regional Disparities in Cardiovascular Surgery and Mortality in Korea: A National Cross-sectional Study.

Regional disparities in cardiovascular care in Korea have led to uneven patient outcomes. Despite the growing need for and access to procedures, few studies have linked regional service availability to mortality rates. This study analyzed regional variation in the utilization of major cardiovascular procedures and their associations with short-term mortality to provide better evidence regarding the relationship between healthcare resource distribution and patient survival. A cross-sectional study was conducted using nationwide claims data for patients who underwent coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), stent insertion, or aortic aneurysm resection in 2022. Regional variation was assessed by the relevance index (RI). The associations between the regional RI and 30-day mortality were analyzed. The RI was lowest for aortic aneurysm resection (mean, 26.2; standard deviation, 26.1), indicating the most uneven regional distribution among the surgical procedures. Patients undergoing this procedure in regions with higher RIs showed significantly lower 30-day mortality (adjusted odds ratio [aOR], 0.73; 95% confidence interval, 0.55 to 0.96; p=0.026) versus those with lower RIs. This suggests that cardiovascular surgery regional availability, as measured by RI, has an impact on mortality rates for certain complex surgical procedures. The RI was not associated with significant mortality differences for more widely available procedures like CABG (aOR, 0.96), PCI (aOR, 1.00), or stent insertion (aOR, 0.91). Significant regional variation and underutilization of cardiovascular surgery were found, with reduced access linked to worse mortality for complex procedures. Disparities should be addressed through collaboration among hospitals and policy efforts to improve outcomes.

#1981 Experience with the use of semaglutide in cardiorenal syndrome patients followed in a cardiorenal unit (CRU)

Abstract Background and Aims GLP-1 receptor agonists are antihyperglycemic drugs that have shown an interesting cardio and nephroprotective effect beyond glycemic control and also induce weight loss, which is likely a facilitating element in the renal and cardioprotection of patients with elevated BMI. Patients with cardiorenal syndrome are often approached as particularly complex cases, which can lead to the underutilization of certain therapeutic groups. We have analyzed the use of semaglutide in patients followed in the CRU of Puerta de Hierro University Hospital to evaluate the drug's efficacy in glycemic and weight control and its safety profile. Method Retrospective real-life analysis performed in patients who received semaglutide while being under follow-up in the CRU, from January 21-December 22. Follow-up time was 6 months. Patients who had previously been on GLP1-AR treatment, on renal replacement therapy, or while waiting for any percutaneous or surgical cardiovascular procedure were excluded from the study. Results 41 patients, 14 on oral semaglutide and 24 on subcutaneous semaglutide were analyzed. Demographic data and main comorbidities are shown in the table and were similar in both formulations. 53% of the patients were on maximum semaglutide dose at the end of follow-up (59.3% sbc and 42.9% oral, p 0.3). Weight loss and decrease in HbA1C% were significant without differences between formulations. We observed a significant decrease in systolic blood pressure of 11.1 (18) p 0.007 also similar in both drug formulations. No significant modifications in renal parameters were observed during follow-up. Adverse events were observed in 9 patients (22%), mainly gastrointestinal intolerance, and were more frequent with oral formulation (50% vs. 7.4%, p 0.004). 6 patients (14%) stopped semaglutide treatment without differences between formulation groups. 3 patients experienced at least one episode of HF decompensation, but no other events, hospitalizations, or deaths were observed. 3 (7.9%) patients experienced an eGFR decrease of&amp;gt; 30% without differences among the formulation groups. Conclusion We conclude that semaglutide in both formulations is an excellent option for glycemic and weight control in CRS patients’ blood pressure, with an additional significant improvement in blood pressure control and a good safety profile in this special population.

Call for Action to target interhospital Variation in Cardiovascular Mortality, Readmissions, and Length-of-Stay: Results of A National Population Analysis.

Excessive interhospital variation threatens healthcare quality. Data on variation in patient outcomes across the whole cardiovascular spectrum are lacking. We aimed to examine interhospital variability for 28 cardiovascular All Patient Refined-Diagnosis-related Groups (APR-DRGs). We studied 103,299 cardiovascular admissions in 99 (98%) Belgian acute-care hospitals between 2012 and 2018. Using generalized linear mixed models, we estimated hospital-specific and APR-DRG-specific risk-standardized rates for in-hospital mortality, 30-day readmissions, and length-of-stay above the APR-DRG-specific 90th percentile. Interhospital variation was assessed based on estimated variance components and time trends between the 2012-2014 and 2016-2018 periods were examined. There was strong evidence of interhospital variation, with statistically significant variation across the 3 outcomes for 5 APR-DRGs after accounting for patient and hospital factors: percutaneous cardiovascular procedures with acute myocardial infarction, heart failure, hypertension, angina pectoris, and arrhythmia. Medical diagnoses, with in particular hypertension, heart failure, angina pectoris, and cardiac arrest, showed strongest variability, with hypertension displaying the largest median odds ratio for mortality (2.51). Overall, hospitals performing at the upper-quartile level should achieve improvements to the median level, and an annual 633 deaths, 322 readmissions, and 1578 extended hospital stays could potentially be avoided. Analysis of interhospital variation highlights important outcome differences that are not explained by known patient or hospital characteristics. Targeting variation is therefore a promising strategy to improve cardiovascular care. Considering their treatment in multidisciplinary teams, policy makers, and managers should prioritize heart failure, hypertension, cardiac arrest, and angina pectoris improvements by targeting guideline implementation outside the cardiology department.
