The contemporary scope of practice of interventional cardiologists (ICs) in the United States and recent trends are unknown. Using Medicare claims from 2013 to 2017, we categorized ICs into 4 practice categories (only percutaneous coronary intervention [PCI], PCI with noninvasive imaging, PCI with specialized interventions [peripheral/structural], and all 3 services) and evaluated associations with region, hospital bed size and teaching status, gender, and graduation year. Of 6,083 ICs in 2017, 10.9% performed only PCI, 68.3% PCI with noninvasive imaging, 5.7% PCI with specialized interventions, and 15.1% all 3 services. A higher proportion of Northeast ICs (vs South ICs) were performing only PCI (24.8% vs 7.3%) and PCI with specialized interventions (12% vs 3.4%), but lower PCI and noninvasive imaging (53.8% vs 71.7%) and all 3 services (9.3% and 17.6%). Regarding ICs at larger hospitals (bed size >575 vs <218), a higher proportion was performing only PCI (23.8% vs 5.2%) or PCI with specialized interventions (13.5% vs 1.7%) and lower proportion was performing PCI with noninvasive imaging (48.8% vs 78%), similar to teaching hospitals. Female ICs (vs male ICs) more frequently performed only PCI (18.9% vs 10.6%) and less frequently all 3 services (8.3% vs 15.4%). A lower proportion of recent graduates (2001 to 2016) performed only PCI (9.8% vs 13.8%) and PCI with noninvasive imaging (66.3% vs 72.6%) but a higher proportion performed all 3 services (18% vs 8.4%) than earlier graduates (1959 to 1984). From 2013 to 2017, only PCI and PCI with noninvasive imaging decreased, whereas PCI and specialized interventions and all 3 services increased (all p <0.001). In conclusion, there is marked heterogeneity in practice responsibilities among ICs, which has implications for training and competency assessments., Competing Interests: Disclosures Dr. Krumholz reported that he has contracts through Yale New Haven Hospital with the Centers for Medicare & Medicaid Services to support quality measurement programs and through Yale with UnitedHealth Group to engage in collaborative research.

Ventricular arrhythmias are the leading cause of sudden cardiac death. Current treatment strategies for ventricular tachycardia, including antiarrhythmic drugs and catheter ablation, have limited efficacy in patients with structural heart disease. Noninvasive ablation with the use of externally applied radiation (cardiac radioablation) has emerged as a promising and novel approach to treating recurrent ventricular tachycardias. However, the heart is generally an "organ at risk" for radiation treatments, such that very little is known on the effects of radiotherapy on cardiac ultrastructure and electrophysiologic properties. Furthermore, there has been limited interaction between the fields of cardiology and radiation oncology and physics. The advent of cardiac radioablation will undoubtedly increase interactions between cardiologists, cardiac electrophysiologists, radiation oncologists and physicists. There is an important knowledge gap separating these specialties, but scientific developments, technical optimisation, and improvements depend on intense multidisciplinary collaboration. This manuscript seeks to review the basic of radiation physics and biology for cardiovascular specialists in an effort to facilitate constructive scientific and clinical collaborations to improve patient outcomes., (Copyright © 2021 Canadian Cardiovascular Society.

Coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the availability of cardiology services and management of cardiac conditions. Elective surgeries, outpatient appointments and cardiac imaging have been largely cancelled across the world due to the risk of infection transmission and the need for reallocation of resources to deal with the increasing number of COVID-19 patients. The impact on patients with cardiac co-morbidities during these times may be drastic. However, cardiologists and hospitals across the world have implemented measures to ensure on-going monitoring and care of patients remotely. In this review, we discuss the impact of COVID-19 on cardiac services including interventional cardiology services, cardiac imaging and outpatient appointments. In addition, implications for future research and clinical practice are also discussed.

Critical care cardiology is a steadily and rapidly developing sub-specialization within cardiovascular medicine, since the first emergence of a coronary care unit in the early 1960s. Today, modern cardiac intensive care units (CICU) serve a complex patient population with a high burden of cardiovascular and non-cardiovascular critical illnesses. Treatment of these patients requires a multidisciplinary approach, with a combination of highly specialized knowledge and skills in cardiovascular diseases, as well as emergency, critical-care and internal medicine. The CICU has always posed special challenges to both experienced intensivists as well as fellows-in-training (FIT) and is certainly one of the most demanding training phases. In recent years, these challenges have grown significantly owing to technological innovations, with new and steadily rising numbers of complex interventional procedures and new options for temporary circulatory support for critically ill patients, such as venoarterial extracorporeal membrane oxygenation (VA-ECMO). Herein, we focus on the successful CICU management of these special patient cohorts, which must become an integral part of critical-care training., (© 2021.

It is now widely recognized that COVID-19 illness can be associated with significant intermediate and potentially longer-term physical limitations. The term, "long COVID-19" is used to define any patient with persistent symptoms after acute COVID-19 infection (ie, after 4 weeks). It is postulated that cardiac injury might be linked to symptoms that persist after resolution of acute infection, as part of this syndrome. The Canadian Cardiovascular Society Rapid Response Team has generated this document to provide guidance to health care providers on the optimal management of patients with suspected cardiac complications of long COVID-19., (Copyright © 2021 Canadian Cardiovascular Society.

Before the coronavirus disease 2019 (COVID-19) pandemic, use of telehealth services had been limited in cardiovascular care. Potential benefits of telehealth include improved access to care, more efficient care management, reduced costs, the ability to assess patients within their homes while involving key caretakers in medical decisions, maintaining social distance, and increased patient satisfaction. Challenges include changes in payment models, issues with data security and privacy, potential depersonalization of the patient-clinician relationship, limitations in the use of digital health technologies, and the potential impact on disparities, including socioeconomic, gender, and age-related issues and access to technology and broadband. Implementation and expansion of telehealth from a policy and reimbursement practice standpoint are filled with difficult decisions, yet addressing these are critical to the future of health care., (Copyright © 2021 Elsevier Inc.

Multiple sodium glucose cotransporter-2 inhibitors (SGLT-2i) and glucagon-like peptide-1 receptor agonists (GLP-1RA) have been shown to impart significant cardiovascular and kidney benefits, but are underused in clinical practice. Both SGLT-2i and GLP-1RA were first studied as glucose-lowering drugs, which may have impeded uptake by cardiologists in the wake of proven cardiovascular efficacy. Their significant effect on cardiovascular and kidney outcomes, which are largely independent of glucose-lowering effects, must drive a broader use of these drugs. Cardiologists are 3 times more likely than endocrinologists to see patients with both type 2 diabetes and cardiovascular disease, thus they are ideally positioned to share responsibility for SGLT-2i and GLP-1RA treatment with primary care providers. In order to increase adoption, SGLT-2i and GLP-1RA must be reframed as primarily cardiovascular and kidney disease risk-reducing agents with a side effect of glucose-lowering. Coordinated and multifaceted interventions engaging clinicians, patients, payers, professional societies, and health systems must be implemented to incentivize the adoption of these medications as part of routine cardiovascular and kidney care. Greater use of SGLT-2i and GLP-1RA will improve outcomes for patients with type 2 diabetes at high risk for cardiovascular and kidney disease.

Cardiovascular magnetic resonance (CMR) has emerged as an accurate diagnostic technique for the evaluation of patients with cardiac disease in the majority of clinical settings, thanks to an established additional diagnostic and prognostic value. This document has been developed by a joined group of experts of the Italian Society of Cardiology (SIC) and Italian Society of Radiology (SIRM) to provide a summary about the current state of technology and clinical applications of CMR, to improve the clinical diagnostic pathways and to promote its inclusion in clinical practice. The writing committee consisted of members and experts of both societies in order to develop a more integrated approach in the field of cardiac imaging. This section 2 will cover myocarditis, pericardial disease, cardiomyopathies and valvular heart disease., (Copyright © 2021 Italian Federation of Cardiology - I.F.C. All rights reserved.)

Background:  Splanchnic vein thrombosis (SVT) is a common complication in patients with liver cirrhosis. The aim of this study was to evaluate the efficacy and safety of anticoagulant therapy for SVT in cirrhotic patients., Methods:  In this systematic review and meta-analysis, studies reporting on SVT recanalization and progression, recurrent venous thromboembolism (VTE), major bleeding, and overall mortality were searched in MEDLINE, EMBASE, and ClinicalTrial.gov up to December 2019. Pooled proportions and risk ratios (RRs) with corresponding 95% confidence intervals (CIs) were calculated., Results:  A total of 1,475 patients were included in 26 studies (23 observational and 3 randomized controlled trials). In patients receiving anticoagulant therapy, SVT recanalization occurred in 68% (95% CI, 62-74; 571/842 patients; 22 studies), SVT progression in 6% (95% CI, 4-9; 25/748 patients; 22 studies), recurrent VTE in 10% (95% CI, 4-22; 48/399 patients; 7 studies), major bleeding in 6% (95% CI, 4-10; 58/785 patients; 18 studies), and overall mortality in 9% (95% CI, 6-14; 68/787 patients; 17 studies). Anticoagulant treatment was associated with higher SVT recanalization (RR 3.19; 95% CI, 1.42-7.17), lower thrombosis progression (RR 0.28; 95% CI, 0.15-0.52), major bleeding (RR 0.52; 95% CI, 0.28-0.97), and overall mortality (RR 0.42; 95% CI, 0.24-0.73) compared with no treatment., Conclusion:  Anticoagulant therapy seems to improve vein recanalization and to reduce SVT progression, major bleeding, and overall mortality in cirrhotic patients with SVT. The incidence of recurrent VTE during anticoagulation remains substantial., Competing Interests: E.V., N.R., O.C., E.P., M.S., A.D.G., and M.M. have nothing to disclose.

A few decades ago, the understanding of the pathophysiological processes involved in the coronary artery thrombus formation has placed anticoagulant and antiplatelet agents at the core of the management of acute coronary syndrome (ACS). Increasingly potent antithrombotic agents have since been evaluated, in various association, timing, or dosage, in numerous randomized controlled trials to interrupt the initial thrombus formation, prevent ischemic complications, and ultimately improve survival. Primary percutaneous coronary intervention, initial parenteral anticoagulation, and dual antiplatelet therapy with potent P2Y 12 inhibitors have become the hallmark of ACS management revolutionizing its prognosis. Despite these many improvements, much more remains to be done to optimize the onset of action of the various antithrombotic therapies, for further treating and preventing thrombotic events without exposing the patients to an unbearable hemorrhagic risk. The availability of various potent P2Y 12 inhibitors has opened the door for individualized therapeutic strategies based on the clinical setting as well as the ischemic and bleeding risk of the patients, while the added value of aspirin has been recently challenged. The strategy of dual-pathway inhibition with P2Y 12 inhibitors and low-dose non-vitamin K antagonist oral anticoagulant has brought promising results for the early and late management of patients presenting with ACS with and without indication for oral anticoagulation. In this updated review, we aimed at describing the evidence supporting the current gold standard of antithrombotic management of ACS. More importantly, we provide an overview of some of the ongoing issues and promising therapeutic strategies of this ever-evolving topic., Competing Interests: J.-P.C. has received research grants or honoraria from AstraZeneca, Bayer, Bristol-Myers Squibb, Daiichi-Sankyo, Eli Lilly, Fédération Française de Cardiologie, Lead-Up, Medtronic, Merck Sharp & Dohme, Sanofi, Servier, and WebMD., (Thieme.

In 1984, the National Heart, Lung, and Blood Institute (NHLBI) decided to study the efficacy and safety of the treatment of acute myocardial infarction with an emerging therapy, coronary thrombolysis, and thus the TIMI (Thrombolysis In Myocardial Infarction) Study Group was born. Following completion of 3 clinical trials of thrombolytic therapy supported by the NHLBI, TIMI became an academic research organization headquartered at Brigham and Women's Hospital and subsequently branched out to study a wide range of patients, including those with stable coronary, cerebrovascular, and peripheral arterial disease; dyslipidemia; heart failure; atrial fibrillation; diabetes; and obesity. TIMI also began to study a wide range of interventions including thrombolytic, antithrombotic, lipid-modifying, anti-inflammatory, heart failure, glucose-lowering, and weight loss agents. TIMI, now in its 37th year, has completed >70 trials. This review describes the origins of the TIMI Study Group, summarizes several of its completed trials and the major lessons learned from them, and discusses ongoing trials and future directions., Competing Interests: Funding Support and Author Disclosures Dr. Sabatine has received research grant support through Brigham and Women’s Hospital from Amgen, Anthos Therapeutics, AstraZeneca, Daiichi-Sankyo, Eisai, Intarcia, The Medicines Company, MedImmune, Merck, Novartis, and Pfizer; and has provided consulting services to Althera, Amgen, Anthos Therapeutics, AstraZeneca, Bristol Myers Squibb, DalCor, Dr. Reddy’s Laboratories, Intarcia, and Merck.

Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of morbidity and mortality across the world, warranting continuous research in this field. The elucidation of the atherogenesis mechanism is considered one of the most relevant scientific accomplishments of the last century. This has led to the clinical development of various novel therapeutic interventions for patients with or at risk of ASCVD, in which randomized clinical trials played a crucial role.The Thrombolysis in Myocardial Infarction (TIMI) Study Group was initially established to conduct a clinical trial studying thrombolysis for treatment of myocardial infarction. However, over the years, the TIMI Study Group has expanded their research interests to include antithrombotic therapy, lipid lowering, anti-diabetes, anti-obesity, and even heart failure. By leading large-scale, international, randomized, controlled trials of novel therapeutics, the TIMI Study Group has helped shape the very practice of cardiovascular medicine for over a quarter of a century, and decades of research continue to provide future promise for further advancement. Through a mutual goal to improve the care of ASCVD patients, the Japanese scientific community has become one of the important contributors to the TIMI Study Group's clinical research.In this review article, the authors aim to summarize major research lead by the TIMI Study Group in the ASCVD field.

Point-of-Care (POC) transthoracic echocardiography (TTE) is transforming the management of patients with cirrhosis presenting with septic shock, acute kidney injury, hepatorenal syndrome and acute-on-chronic liver failure (ACLF) by correctly assessing the hemodynamic and volume status at the bedside using combined echocardiography and POC ultrasound (POCUS). When POC TTE is performed by the hepatologist or intensivist in the intensive care unit (ICU), and interpreted remotely by a cardiologist, it can rule out cardiovascular conditions that may be contributing to undifferentiated shock, such as diastolic dysfunction, myocardial infarction, myocarditis, regional wall motion abnormalities and pulmonary embolism. The COVID-19 pandemic has led to a delay in seeking medical treatment, reduced invasive interventions and deferment in referrals leading to "collateral damage" in critically ill patients with liver disease. Thus, the use of telemedicine in the ICU (Tele-ICU) has integrated cardiology, intensive care, and hepatology practices across the spectrum of ICU, operating room, and transplant healthcare. Telecardiology tools have improved bedside diagnosis when introduced as part of COVID-19 care by remote supervision and interpretation of POCUS and echocardiographic data. In this review, we present the contemporary approach of using POC echocardiography and offer a practical guide for primary care hepatologists and gastroenterologists for cardiac assessment in critically ill patients with cirrhosis and ACLF. Evidenced based use of Tele-ICU can prevent delay in cardiac diagnosis, optimize safe use of expert resources and ensure timely care in the setting of critically ill cirrhosis, ACLF and liver transplantation in the COVID-19 era.

Due to the COVID-19 pandemic, the 84 th Annual Meeting of the Japanese Circulation Society (JCS) was held in a web-based format for the first time in its history as "The Week for JCS 2020" from Monday, July 27 to Sunday, August 2, 2020. All sessions, including general abstracts, were streamed live or on-demand. The main theme of the meeting was "Change Practice!" and the aim was to organize the latest findings in the field of cardiovascular medicine and discuss how to change practice. The total number of registered attendees was over 16,800, far exceeding our expectations, and many of the sessions were viewed by far more people than at conventional face-to-face scientific meetings. At this conference, the power of online information dissemination was fully demonstrated, and the evolution of online academic meetings will be a direction that cannot be reversed in the future. The meeting was completed with great success, and we express our heartfelt gratitude to all affiliates for their enormous amount of work, cooperation, and support.

Telemedicine involves diagnostic, therapeutic and educational services being offered remotely by healthcare professionals to exchange crucial clinical information. It is a rapidly developing form of medical activity and part of medical industry, with advanced technologies already available in Poland. Cardiology is one of the fields in which telemedicine methods were pioneered and introduced into everyday practice. Some of these methods have already become standard procedures for diagnosis and treatment in some Polish centers, with other soon to follow. Clinical study results not only demonstrate reliability and usefulness of telemedicine technologies but also show that their use in clinical practice improves the patients' prognoses and quality of life. Moreover, study results in highly developed countries show a potential cost-effectiveness of telemedicine from the perspective of healthcare systems. There is an unquestionable need to establish clear rules for telemedicine use in Poland, which would ensure their high quality and adequate clinical application. This paper is a summary of the current status of telemedicine solutions used in cardiology, with a particular focus on the Polish healthcare system, and presents both the commonly available solutions and those that are expected to develop rapidly in the near future.

In medical imaging, Artificial Intelligence is described as the ability of a system to properly interpret and learn from external data, acquiring knowledge to achieve specific goals and tasks through flexible adaptation. The number of possible applications of Artificial Intelligence is also huge in clinical medicine and cardiovascular diseases. To describe for the first time in literature, the main results of articles about Artificial Intelligence potential for clinical applications in molecular imaging techniques, and to describe its advancements in cardiovascular diseases assessed with nuclear medicine imaging modalities. A comprehensive search strategy was used based on SCOPUS and PubMed databases. From all studies published in English, we selected the most relevant articles that evaluated the technological insights of AI in nuclear cardiology applications. Artificial Intelligence may improve patient care in many different fields, from the semi-automatization of the medical work, through the technical aspect of image preparation, interpretation, the calculation of additional factors based on data obtained during scanning, to the prognostic prediction and risk-- group selection. Myocardial implementation of Artificial Intelligence algorithms in nuclear cardiology can improve and facilitate the diagnostic and predictive process, and global patient care. Building large databases containing clinical and image data is a first but essential step to create and train automated diagnostic/prognostic models able to help the clinicians to make unbiased and faster decisions for precision healthcare., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

The rapidly expanding field of preventive cardiology has brought with it several major advances in the past decade. Changes in guidelines for cholesterol mangement focusing on the identification of "statin eligible groups" and removal of actual low-density lipoprotein cholesterol (LDL-C) targets, in particular, as well as lower targets for blood pressure in updated hypertension guidelines, have made a major impact on healthcare. The availability of the sodium glucose transport protein-2 (SGLT2) inhibitors and glucagon-like peptide -1 receptor antagonists (GLP1-RA) for managing diabetes have shifted our focus in diabetes care beyond glucose lowering to addressing cardiovascular risk reduction. While many prior trials of fish oil therapy have failed to show benefit, the recent Reduction of Cardiovascular Events With EPA - Intervention Trial (REDUCE-IT) testing the efficacy of icosapent ethyl has shown dramatic benefit in further addressing residual atherosclerotic cardiovascular disease (ASCVD) risk beyond statin therapy not only in those with known ASCVD, but also in diabetic patients with multiple risk factors. The past decade also ushered in confirmation of the inflammation hypothesis of atherosclerosis with the Canakinumab Anti-Inflammatory Thrombosis Outcomes Study (CANTOS) using canakinumab, despite the fact the therapy was not approved by the Food and Drug Administration (FDA) for cardiovascular risk reduction. Also, to improve our understanding of heart disease in women, the emergence of novel concepts of ischemia or myocardial infarction in those with normal or nonobstructive atherosclerotic disease has been a major advance. Moreover, the past decade brought the emergence of proprotein convertase subtilisin/kexin type 9 (PCSK9) monoclonal antibody therapy and the cardiovascular risk reduction benefits seen in the Further Cardiovascular Outcomes Research with PCSK9 Inhibition in Subjects with Elevated Risk (FOURIER) and Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab (ODYSSEY OUTCOMES) trials, providing further evidence-based therapy for additional reduction of ASCVD risk beyond statin therapy. The PCSK9 monoclonal antibodies have facilitated the attainment of LDL-C levels never previously thought possible. Finally with the mRNA interference therapy inclisiran in development, we may soon have a "vaccine-like" approach for addressing dyslipidemia and atherosclerosis., (Copyright © 2019 Elsevier Inc.

The role of cardiac surgeons in the treatment of aortic valve disease is changing with the expansion of transcatheter aortic valve replacement. Recent trials in patients at low surgical risk will further this paradigm shift, and the future cardiac surgeons in this space remain uncertain. In this Viewpoint article, we discuss the role that surgeons can play in the future of structural heart medicine. We examine the potential effects of the low-risk transcatheter aortic valve replacement trials on overall operative volumes and how these effects may be limited through structured training programs and strong collaboration within the heart team. Finally, future considerations and cautions for the cardiac surgical community are discussed. The coming era presents an opportunity for growth, leadership, and strong interdisciplinary collaboration for the cardiac surgery community., (Crown Copyright © 2020. Published by Elsevier Inc.

Background: The coronavirus disease 2019 (COVID-19) pandemic brought about abrupt changes in the way health care is delivered, and the impact of transitioning outpatient clinic visits to telehealth visits on processes of care and outcomes is unclear., Methods: We evaluated ordering patterns during cardiovascular telehealth clinic visits in the Duke University Health System between March 15 and June 30, 2020 and 30-day outcomes compared with in-person visits in the same time frame in 2020 and in 2019., Results: Within the Duke University Health System, there was a 33.1% decrease in the number of outpatient cardiovascular visits conducted in the first 15 weeks of the COVID-19 pandemic, compared with the same time period in 2019. As a proportion of total visits initially booked, 53% of visits were cancelled in 2020 compared to 35% in 2019. However, patients with cancelled visits had similar demographics and comorbidities in 2019 and 2020. Telehealth visits comprised 9.3% of total visits initially booked in 2020, with younger and healthier patients utilizing telehealth compared with those utilizing in-person visits. Compared with in-person visits in 2020, telehealth visits were associated with fewer new (31.6% for telehealth vs 44.6% for in person) or refill (12.9% vs 15.6%, respectively) medication prescriptions, electrocardiograms (4.3% vs 31.4%), laboratory orders (5.9% vs 21.8%), echocardiograms (7.3% vs 98%), and stress tests (4.4% vs 6.6%). When adjusted for age, race, and insurance status, those who had a telehealth visit or cancelled their visit were less likely to have an emergency department or hospital encounter within 30 days compared with those who had in-person visits (adjusted rate ratios (aRR) 0.76 [95% 0.65, 0.89] and aRR 0.71 [95% 0.65, 0.78], respectively)., Conclusions: In response to the perceived risks of routine medical care affected by the COVID-19 pandemic, different phenotypes of patients chose different types of outpatient cardiology care. A better understanding of these differences could help define necessary and appropriate mode of care for cardiology patients., Competing Interests: Declaration of Competing Interest No conflicts relevant to this work for all authors., (Copyright © 2020 Elsevier Inc.

In recent times cardiovascular diseases (CVDs) are the leading cause of mortality universally, caused more or less 17.7 million casualties with 45% of all illnesses (except communicable ones) in 2015 as per World Health Organization (WHO). According to American National Center for Health Statistics, cardiac disorders are costliest. Moreover, health care expenditures related to cardiac disorders are anticipated to exceed than diabetes and Alzheimer's. Straining of reactive oxygen species with diminished neutralization & inflammation critically adds to atherosclerosis and also proceed to other cardiovascular diseases such as cardiac remodeling and myocardial infarction (MI). In the past few years, researchers revealed multiple drug targets from animal studies and evaluated them in the therapeutics of cardiac disorders, which offered exciting clues for novel therapeutic strategies. Although, only few newer agents approved clinically and actual approaches for treatment are lagging behind. Several novel drugs found effective for the treatment of hypertension, congestive heart failure, cardiac arrhythmia and angina pectoris. Detailed mechanism of action, basic and clinical pharmacology of all novel drugs has been discussed in this review.

Health system reforms across high- and middle-income countries often involve changes to public hospital governance. Corporatization is one such reform, in which public sector hospitals are granted greater functional independence while remaining publicly owned. In theory, this can improve public hospital efficiency, while retaining a public service ethos. However, the extent to which efficiency gains are realized and public purpose is maintained depends on policy choices about governance and payment systems. We present a case study of Malaysia's National Heart Institute (IJN), which was created in 1992 by corporatization of one department in a large public hospital. The aim of the paper is to examine whether IJN has achieved the goals for which it was created, and if so, whether it provides a potential model for further reforms in Malaysia and other similar health systems. Using a combination of document analysis and key informant interviews, we examine key governance, health financing and payment, and equity issues. For governance, we highlight the choice to have IJN owned by and answerable to a Ministry of Finance (MOF) holding company and MOF-appointed board, rather than the Ministry of Health (MOH). On financing and payment, we analyze the implications of IJN's combined role as fee-for-service provider to MOH as well as provider of care to private patients. For equity, we analyze the targeting of IJN care across publicly-referred and private patients. These issues demonstrate unresolved tensions between IJN's objectives and public service goals. As an institutional innovation that has endured for 28 years and grown dramatically in size and revenue, IJN's trajectory offers critical insights on the relevance of the hybrid public-private models for hospitals in Malaysia as well as in other middle-income countries. While IJN appears to have achieved its goal of establishing itself as a commercially viable, publicly owned center of clinical excellence in Malaysia, the value for money and equity of the services it provides to the Ministry of Health remain unclear. IJN is accountable to a small Ministry of Finance holding company, which means that detailed information required to evaluate these critical questions is not published. The case of IJN highlights that corporatization cannot achieve its stated goals of efficiency, innovation, and equity in isolation; rather it must be supported by broader reforms, including of health financing, payment, governance, and transparency, in order to ensure that autonomous hospitals improve quality and provide efficient care in an equitable way.
