Smoking and Provision of Smoking Cessation Interventions among Inpatients with Acute Coronary Syndrome in China: Findings from the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome Project.

Highlights: Over half of male acute coronary syndrome patients were smokers in China.Smoking was associated with higher risk of critical cardiac symptoms at admission.Only 35.3% of smoking patients received smoking cessation interventions in China. Background: Smoking cessation is recognized as an effective and cost-effective strategy for improving the prognosis of patients with coronary heart disease. Despite this, few studies have evaluated the smoking prevalence and provision of smoking cessation interventions among patients with acute coronary syndrome (ACS) in China. Objectives: To evaluate the smoking prevalence, clinical conditions and in-hospital outcomes associated with smoking, and the provision of smoking cessation interventions among ACS patients in China. Methods: This registry study was conducted using data from the Improving Care for Cardiovascular Disease in China project, a collaborative nationwide registry of the American Heart Association and the Chinese Society of Cardiology. Our study sample comprised 92,509 ACS inpatients admitted between November 2014 and December 2018. A web-based data collection platform was used to report required data. Results: Smoking prevalence among male and female ACS patients was 52.4% and 8.0%, respectively. Patients younger than 45 years had the highest smoking rate (men: 68.0%; women: 14.9%). Compared with non-smokers, smokers had an earlier onset age of ACS and a greater proportion of severe clinical manifestations at admission, including ST-elevation myocardial infarction (67.8% versus 54.8%; p < 0.001) and substantially elevated myocardial injury markers (86.1% versus 83.0%; p < 0.001). After multivariable adjustment, smoking was associated with higher risk of critical cardiac symptoms at admission (OR = 1.14, 95% CI: 1.08-1.20; p < 0.001) and had no direct association with in-hospital outcomes (OR = 0.93, 95% CI: 0.84-1.02; p = 0.107) of ACS patients. Of 37,336 smokers with ACS, only 35.3% received smoking cessation interventions before discharge. There was wide variation in provision of smoking cessation interventions across hospitals (0%-100%). Conclusions: Smoking is highly prevalent among ACS patients in China. However, smoking cessation interventions are not widely adopted in clinical practice in China as part of formal treatment strategies for ACS patients, indicating an important target for quality improvement.

The American Heart Association's Call to Action for Reducing the Global Burden of Rheumatic Heart Disease: A Policy Statement From the American Heart Association.

Rheumatic heart disease (RHD) affects ≈40 million people and claims nearly 300 000 lives each year. The historic passing of a World Health Assembly resolution on RHD in 2018 now mandates a coordinated global response. The American Heart Association is committed to serving as a global champion and leader in RHD care and prevention. Here, we pledge support in 5 key areas: (1) professional healthcare worker education and training, (2) technical support for the implementation of evidence-based strategies for rheumatic fever/RHD prevention, (3) access to essential medications and technologies, (4) research, and (5) advocacy to increase global awareness, resources, and capacity for RHD control. In bolstering the efforts of the American Heart Association to combat RHD, we hope to inspire others to collaborate, communicate, and contribute.

Chest Pain Center Accreditation Is Associated With Improved In-Hospital Outcomes of Acute Myocardial Infarction Patients in China: Findings From the CCC-ACS Project.

Background Chest pain center (CPC) accreditation plays an important role in the management of acute myocardial infarction (AMI). However, no evidence shows whether the outcomes of AMI patients are improved with CPC accreditation in China. Methods and Results This retrospective analysis is based on a predesigned nationwide registry, CCC-ACS (Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome). The primary outcome was major adverse cardiovascular events (MACE), including all-cause death, reinfarction, stent thrombosis, stroke, and heart failure. A total of 15 344 AMI patients, from 40 CPC-accredited hospitals, were enrolled, including 7544 admitted before and 7800 after accreditation. In propensity score matching, 6700 patients in each group were matched. The incidence of 7-day MACE (6.7% versus 8.0%; P=0.003) and all-cause death (1.1% versus 1.6%; P=0.021) was lower after accreditation. In multivariate adjusted mixed-effects Cox proportional hazards models, CPC accreditation was associated with significantly decreased risk of MACE (hazard ratio: 0.78; 95% CI, 0.68-0.91) and all-cause death (hazard ratio: 0.71; 95% CI, 0.51-0.99). The risk of MACE and all-cause death both followed a reverse J-shaped trend: the risk of MACE and all-cause death decreased gradually after achieving CPC accreditation, with minimal risk occurring in the first year, but increased in the second year and after. Conclusions Based on a large-scale national registry data set, CPC accreditation was associated with better in-hospital outcomes for AMI patients. However, the benefits seemed to attenuate over time, and reaccreditation may be essential for maintaining AMI care quality and outcomes.

Prehospital statin use and low-density lipoprotein cholesterol levels at admission in acute coronary syndrome patients with history of myocardial infarction or revascularization: Findings from the Improving Care for Cardiovascular Disease in China (CCC) project.

BACKGROUND: Lowering low-density lipoprotein cholesterol (LDL-C) by statins is a key strategy for secondary prevention of acute coronary syndrome (ACS). However, few studies have examined prehospital statin use and admission LDL-C levels in ACS patients with history of myocardial infarction (MI) or revascularization. This study aimed to assess use of prehospital statins and LDL-C levels at admission in ACS patients with history of MI or revascularization. METHODS: Improving Care for Cardiovascular Disease in China project was a nationwide registry, with 192 participating hospitals reporting details of clinical information of ACS patients from November 2014. By May 2018, 80,282 patients with ACS were included. LDL-C levels were obtained from the initial admission lipid testing. RESULTS: Of the 80,282 ACS patients, 6,523 with a history of MI or revascularization were enrolled. Among them, 50.8% were receiving lipid-lowering therapy before hospitalization (statin monotherapy in 98.4%, combination in 1.2%). A total of 30.1% of patients had LDL-C < 70 mg/dL at admission. In patients receiving prehospital statins, 36.1% had LDL-C < 70 mg/dL compared to 24.0% without prehospital statins (P < .001). At discharge, 91.8% of patients were treated with statin monotherapy, 90.7% at moderate doses irrespective of prehospital statin use and LDL-C levels at admission. CONCLUSIONS: Among ACS patients with history of MI or revascularization, half were not being treated with statin therapy prior to admission, and most had not attained LDL-C < 70 mg/dL despite prehospital statin use. There is an important opportunity to provide intensive statin or combination lipid-lowering therapy to these very high risk patients.

Performance on management strategies with Class I Recommendation and A Level of Evidence among hospitalized patients with non-ST-segment elevation acute coronary syndrome in China: Findings from the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome (CCC-ACS) project.

BACKGROUND: This study aimed to examine hospital performance on evidence-based management strategies for non-ST-segment elevation acute coronary syndrome (NSTE-ACS) and variations across hospitals. METHODS: Improving Care for Cardiovascular Disease in China (CCC)-ACS project is an ongoing registry and quality improvement project, with 150 tertiary hospitals recruited across China. We examined hospital performance on nine management strategies (Class I Recommendations with A Level of Evidence) based on established guidelines. We also evaluated the proportion of patients receiving defect-free care, which was defined as the care that included all the required management strategies for which the patient was eligible. The hospital-level variations in the performance were examined. RESULTS: From 2014 to 2018, 28,170 NSTE-ACS patients were included. Overall, 16% of patients received defect-free care. Higher-performing metrics were statin at discharge (93%), cardiac troponin measurement (92%), dual antiplatelet therapy (DAPT) within 24 hours (90%), and DAPT at discharge (85%). These were followed by metrics of ß-blocker at discharge (69%), angiotensin converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB) at discharge (59%), and risk stratification (56%). Lower-performing metrics were smoking cessation counseling (35%) and percutaneous coronary intervention (PCI) within recommended times (33%). The proportion of patients receiving defect-free care substantially varied across hospitals, ranging from 0% to 58% (Median (interquartile range):12% (7%-21%)). There were large variations across hospitals in performance on risk stratification, smoking cessation counseling, PCI within recommended times, ACEI/ARB at discharge and ß-blocker at discharge. CONCLUSIONS: About one in six NSTE-ACS patients received defect-free care, and the performance varied across hospitals.

Sex Differences in In-Hospital Management and Outcomes of Patients With Acute Coronary Syndrome.

BACKGROUND: Coronary heart disease is a leading cause of mortality among women. Systematic evaluation of the quality of care and outcomes in women hospitalized for acute coronary syndrome (ACS), an acute manifestation of coronary heart disease, remains lacking in China. METHODS: The CCC-ACS project (Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome) is an ongoing nationwide registry of the American Heart Association and the Chinese Society of Cardiology. Using data from the CCC-ACS project, we evaluated sex differences in acute management, medical therapies for secondary prevention, and in-hospital mortality in 82 196 patients admitted for ACS at 192 hospitals in China from 2014 to 2018. RESULTS: Women with ACS were older than men (69.0 versus 61.1 years, P<0.001) and had more comorbidities. After multivariable adjustment, eligible women were less likely to receive evidence-based acute treatments for ACS than men, including early dual antiplatelet therapy, heparins during hospitalization, and reperfusion therapy for ST-segment-elevation myocardial infarction. With respect to strategies for secondary prevention, eligible women were less likely to receive dual antiplatelet therapy, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, statins at discharge, and smoking cessation and cardiac rehabilitation counseling during hospitalization. In-hospital mortality rate was higher in women than in men (2.60% versus 1.50%, P<0.001). The sex difference in in-hospital mortality was no longer observed in patients with ST-segment-elevation myocardial infarction (adjusted odds ratio, 1.18; 95% CI, 1.00 to 1.41; P=0.057) and non-ST-segment elevation ACS (adjusted odds ratio, 0.84; 95% CI, 0.66 to 1.06; P=0.147) after adjustment for clinical characteristics and acute treatments. CONCLUSIONS: Women hospitalized for ACS in China received acute treatments and strategies for secondary prevention less frequently than men. The observed sex differences in in-hospital mortality were mainly attributable to worse clinical profiles and fewer evidence-based acute treatments provided to women with ACS. Specially targeted quality improvement programs may be warranted to narrow sex-related disparities in quality of care and outcomes in patients with ACS.

Prevalence and in-hospital outcomes of diabetes among patients with acute coronary syndrome in China: findings from the Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome Project.

BACKGROUND: Guidelines have classified patients with acute coronary syndrome (ACS) and diabetes as a special population, with specific sections presented for the management of these patients considering their extremely high risk. However, in China up-to-date information is lacking regarding the burden of diabetes in patients with ACS and the potential impact of diabetes status on the in-hospital outcomes of these patients. This study aims to provide updated estimation for the burden of diabetes in patients with ACS in China and to evaluate whether diabetes is still associated with excess risks of early mortality and major adverse cardiovascular and cerebrovascular events (MACCE) for ACS patients. METHODS: The Improving Care for Cardiovascular Disease in China-ACS Project was a collaborative study of the American Heart Association and the Chinese Society of Cardiology. A total of 63,450 inpatients with a definitive diagnosis of ACS were included. Prevalence of diabetes was evaluated in the overall study population and subgroups. Multivariate logistic regression was performed to examine the association between diabetes and in-hospital outcomes, and a propensity-score-matched analysis was further conducted. RESULTS: Among these ACS patients, 23,880 (37.6%) had diabetes/possible diabetes. Both STEMI and NSTE-ACS patients had a high prevalence of diabetes/possible diabetes (36.8% versus 39.0%). The prevalence of diabetes/possible diabetes was higher in women (45.0% versus 35.2%, p < 0.001). Even in patients younger than 45 years, 26.9% had diabetes/possible diabetes. While receiving comparable treatments for ACS, diabetes/possible diabetes was associated with a twofold higher risk of all-cause death (adjusted odds ratio 2.04 [95% confidence interval 1.78-2.33]) and a 1.5-fold higher risk of MACCE (adjusted odds ratio 1.54 [95% confidence interval 1.39-1.72]). CONCLUSIONS: Diabetes was highly prevalent in patients with ACS in China. Considerable excess risks for early mortality and major adverse cardiovascular events were found in these patients. Trial registration NCT02306616. Registered December 3, 2014.

Rationale and design of the improving Care for Cardiovascular Disease in China (CCC) project: a national registry to improve management of atrial fibrillation.

INTRODUCTION: Inadequate management of patients with atrial fibrillation (AF) has been reported in China for anticoagulation therapy and treatment for concomitant diseases. An effective quality improvement programme has been lacking to promote the use of evidence-based treatments and improve outcome in patients with AF. METHODS AND ANALYSIS: The Improving Care for Cardiovascular Disease in China-AF programme is a collaboration of the American Heart Association and the Chinese Society of Cardiology. This programme is designed to promote adherence to AF guideline recommendations and outcomes for inpatients with AF. Launched in February 2015, 150 hospitals are recruited by geographic-economic regions across 30 provinces in China. Each month, 10-20 inpatients with AF are enrolled in each hospital. A web-based data collection platform is used to collect clinical information for patients with AF, including patients' demographics, admission information, medical history, in-hospital care and outcomes, and discharge medications for managing AF. The quality improvement initiative includes monthly benchmarked reports on hospital quality, training sessions, regular webinars and recognitions of hospital quality achievement. Primary analyses will include adherence to performance measures and guidelines. To address intrahospital correlation, generalised estimating equation models will be applied. As of March 2017, 28 801 AF inpatients have been enrolled. ETHICS AND DISSEMINATION: This study protocol was approved by the Ethics Committee of Beijing Anzhen Hospital, Capital Medical University. Results will be published in peer-reviewed medical journals. TRIAL REGISTRATION NUMBER: NCT02309398.

In-Hospital Outcomes of Dual Loading Antiplatelet Therapy in Patients 75 Years and Older With Acute Coronary Syndrome Undergoing Percutaneous Coronary Intervention: Findings From the CCC-ACS (Improving Care for Cardiovascular Disease in China-Acute Coronary Syndrome) Project.

BACKGROUND: Elderly patients with acute coronary syndrome (ACS) are at high risk for ischemic and bleeding events. This study aimed to evaluate the clinical effectiveness and safety of dual loading antiplatelet therapy for patients 75 years and older undergoing percutaneous coronary intervention for ACS. METHODS AND RESULTS: The Improving Care for Cardiovascular Disease in China-ACS project was a collaborative study of the American Heart Association and Chinese Society of Cardiology. A total of 5887 patients 75 years and older with ACS who had percutaneous coronary intervention and received dual antiplatelet therapy with aspirin and P2Y12 inhibitors (clopidogrel or ticagrelor) between November 2014 and June 2017 were enrolled. The primary effectiveness and safety outcomes were in-hospital major adverse cardiovascular events and major bleeding. Hazard ratios (HRs) of in-hospital outcomes with different loading statuses of antiplatelet therapy were estimated using Cox proportional hazard models with multivariate adjustment. A propensity score-matched analysis was also conducted. Compared with patients receiving a dual nonloading dose, patients taking a dual loading dose had increased risks of both major adverse cardiovascular events (HR, 1.66, 95% confidence interval, 1.13-2.44; [P=0.010]) and major bleeding (HR, 2.34, 95% confidence interval, 1.75-3.13; [P<0.001]). Among 3284 propensity score-matched patients, a dual loading dose was associated with a 1.36-fold risk of major adverse cardiovascular events (HR, 1.36; 95% confidence interval, 0.88-2.11 [P=0.168]) and a 2.08-fold risk of major bleeding (HR, 2.08; 95% confidence interval, 1.47-2.93 [P<0.001]). CONCLUSIONS: A dual loading dose of antiplatelet therapy was associated with increased major bleeding risk but not with decreased major adverse cardiovascular events risk among patients 75 years and older undergoing percutaneous coronary intervention for ACS in China.

Invasive Management Strategies and Antithrombotic Treatments in Patients With Non-ST-Segment-Elevation Acute Coronary Syndrome in China: Findings From the Improving CCC Project (Care for Cardiovascular Disease in China).

BACKGROUND: Early invasive strategies and antithrombotic treatments are key treatments of non-ST-segment-elevation acute coronary syndrome (NSTE-ACS). Few studies have examined the use of these strategies in patients with NSTE-ACS in China. This study aimed to assess the applications of invasive strategies and antithrombotic treatments in patients with NSTE-ACS and compare their outcomes. METHODS AND RESULTS: A nationwide registry study, Improving CCC (Care for Cardiovascular Disease in China) ACS project, was launched in 2014 as a collaborative study of the American Heart Association and Chinese Society of Cardiology (CSC), with 142 participating hospitals reporting details of clinical management and outcomes of patients with NSTE-ACS. The use of invasive strategies and antithrombotic treatments was examined based on updated guidelines. Major adverse cardiovascular events were analyzed. A total of 9953 patients with NSTE-ACS were enrolled. Angiography was performed in 63.1% of these patients, and 58.2% underwent percutaneous coronary intervention (PCI). However, 40.6% of patients did not undergo early risk assessment, and very-high-risk patients had the lowest proportion of PCI (41.7%). PCI was performed within recommended times in 11.1% of very-high-risk patients and 26.3% of high risk patients. Those who underwent PCI within 2 hours had higher mortality in high-risk and very-high-risk patients who received PCI. Early dual antiplatelet treatment was given in 88.3% of patients. CONCLUSIONS: There are notable differences between guideline recommendations and the clinical management of patients with NSTE-ACS in China. The reasons for very-high-risk NSTE-ACS patients not undergoing PCI, and the optimal timing of PCI, require further clarification. CLINICAL TRIAL REGISTRATION: URL: http://www.clinicaltrials.gov.

Is endocarditis prophylaxis for dental procedures necessary?

OBJECTIVES: Our purpose is to address whether antimicrobial prophylaxis is necessary before certain dental procedures for patients at increased risk for acquiring infective endocarditis (IE). METHODS: We reviewed recommendations for IE prophylaxis made by the American Heart Association (AHA) from 1995 to the present time. We also compared and contrasted the current recommendations from the AHA, European Society of Cardiology (ESC), United Kingdom's National Institute for Health and Care Excellence (NICE) and a consortium of French organisations. We further reviewed recent papers that have observed the incidence of IE since these current recommendations were published. RESULTS: Beginning in the 1990s, questions were raised about the advisability of using antimicrobial prophylaxis before certain dental procedures to prevent IE. Various groups in Europe and the US were increasingly aware that there were not any clinical trials showing the effectiveness, or lack thereof, of such prophylaxis. In the early to mid-2000s, the AHA, ESC and French consortium published guidelines recommending restriction of prophylaxis before dental procedures to patients with highest risk for developing IE and/or the highest risk for an adverse outcome from IE. The NICE guidelines eliminated recommendations for prophylaxis before dental procedures. Studies published after these changes were instituted have generally shown that the incidence of IE has not changed, although two recent reports have observed some increased incidence (but not necessarily related to an antecedent dental procedure). CONCLUSION: A multi-national randomised controlled clinical trial that would include individuals from both developed and developing countries around the world is needed to ultimately define whether there is a role for antibiotic prophylaxis administered before certain dental procedures to prevent IE.

Rationale and design of the Improving Care for Cardiovascular Disease in China (CCC) project: A national effort to prompt quality enhancement for acute coronary syndrome.

BACKGROUND: A sizeable gap exists between guideline recommendations for treatment of acute coronary syndrome (ACS) and application of these recommendations in clinical practice. The CCC-ACS project is a novel national quality enhancement registry designed to help medical care providers bridge this gap, thereby improving clinical outcomes for ACS patients in China. METHODS AND RESULTS: The CCC-ACS project uses data collection, analysis, feedback, rapid-cycle improvement, and performance recognition to extend the use of evidence-based guidelines throughout the health care system and improve cardiovascular health. The project was launched in 2014, with 150 centers recruited representing the diversity of care for ACS patients in tertiary hospitals across China. Clinical information for patients with ACS is collected via a Web-based data collecting platform, including patients' demographics, medical history, symptoms on arrival, in-hospital treatment and procedures, in-hospital outcomes, and discharge medications for secondary prevention. Improvement in adherence to guideline recommendations is facilitated through monthly benchmarked hospital quality reports, recognition of hospital quality achievement, and regular webinars. As of April 16, 2016, a total of 35,616 ACS cases have been enrolled. CONCLUSIONS: The CCC-ACS is a national hospital-based quality improvement program, aiming to increase adherence to ACS guidelines in China and improve patient outcomes.

The Heart of 25 by 25: Achieving the Goal of Reducing Global and Regional Premature Deaths From Cardiovascular Diseases and Stroke: A Modeling Study From the American Heart Association and World Heart Federation.

In 2011, the United Nations set key targets to reach by 2025 to reduce the risk of premature noncommunicable disease death by 25% by 2025. With cardiovascular disease being the largest contributor to global mortality, accounting for nearly half of the 36 million annual noncommunicable disease deaths, achieving the 2025 goal requires that cardiovascular disease and its risk factors be aggressively addressed. The Global Cardiovascular Disease Taskforce, comprising the World Heart Federation, American Heart Association, American College of Cardiology Foundation, European Heart Network, and European Society of Cardiology, with expanded representation from Asia, Africa, and Latin America, along with global cardiovascular disease experts, disseminates information and approaches to reach the United Nations 2025 targets. The writing committee, which reflects Global Cardiovascular Disease Taskforce membership, engaged the Institute for Health Metrics and Evaluation, University of Washington, to develop region-specific estimates of premature cardiovascular mortality in 2025 based on various scenarios. Results show that >5 million premature CVD deaths among men and 2.8 million among women are projected worldwide by 2025, which can be reduced to 3.5 million and 2.2 million, respectively, if risk factor targets for blood pressure, tobacco use, diabetes mellitus, and obesity are achieved. However, global risk factor targets have various effects, depending on region. For most regions, United Nations targets for reducing systolic blood pressure and tobacco use have more substantial effects on future scenarios compared with maintaining current levels of body mass index and fasting plasma glucose. However, preventing increases in body mass index has the largest effect in some high-income countries. An approach achieving reductions in multiple risk factors has the largest impact for almost all regions. Achieving these goals can be accomplished only if countries set priorities, implement cost-effective population wide strategies, and collaborate in public-private partnerships across multiple sectors.

Infective Endocarditis in Adults: Diagnosis, Antimicrobial Therapy, and Management of Complications: A Scientific Statement for Healthcare Professionals From the American Heart Association.

BACKGROUND: Infective endocarditis is a potentially lethal disease that has undergone major changes in both host and pathogen. The epidemiology of infective endocarditis has become more complex with today's myriad healthcare-associated factors that predispose to infection. Moreover, changes in pathogen prevalence, in particular a more common staphylococcal origin, have affected outcomes, which have not improved despite medical and surgical advances. METHODS AND RESULTS: This statement updates the 2005 iteration, both of which were developed by the American Heart Association under the auspices of the Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease, Council on Cardiovascular Disease of the Young. It includes an evidence-based system for diagnostic and treatment recommendations used by the American College of Cardiology and the American Heart Association for treatment recommendations. CONCLUSIONS: Infective endocarditis is a complex disease, and patients with this disease generally require management by a team of physicians and allied health providers with a variety of areas of expertise. The recommendations provided in this document are intended to assist in the management of this uncommon but potentially deadly infection. The clinical variability and complexity in infective endocarditis, however, dictate that these recommendations be used to support and not supplant decisions in individual patient management.

Revision of the Jones Criteria for the diagnosis of acute rheumatic fever in the era of Doppler echocardiography: a scientific statement from the American Heart Association.

BACKGROUND: Acute rheumatic fever remains a serious healthcare concern for the majority of the world's population despite its decline in incidence in Europe and North America. The goal of this statement was to review the historic Jones criteria used to diagnose acute rheumatic fever in the context of the current epidemiology of the disease and to update those criteria to also take into account recent evidence supporting the use of Doppler echocardiography in the diagnosis of carditis as a major manifestation of acute rheumatic fever. METHODS AND RESULTS: To achieve this goal, the American Heart Association's Council on Cardiovascular Disease in the Young and its Rheumatic Fever, Endocarditis, and Kawasaki Disease Committee organized a writing group to comprehensively review and evaluate the impact of population-specific differences in acute rheumatic fever presentation and changes in presentation that can result from the now worldwide availability of nonsteroidal anti-inflammatory drugs. In addition, a methodological assessment of the numerous published studies that support the use of Doppler echocardiography as a means to diagnose cardiac involvement in acute rheumatic fever, even when overt clinical findings are not apparent, was undertaken to determine the evidence basis for defining subclinical carditis and including it as a major criterion of the Jones criteria. This effort has resulted in the first substantial revision to the Jones criteria by the American Heart Association since 1992 and the first application of the Classification of Recommendations and Levels of Evidence categories developed by the American College of Cardiology/American Heart Association to the Jones criteria. CONCLUSIONS: This revision of the Jones criteria now brings them into closer alignment with other international guidelines for the diagnosis of acute rheumatic fever by defining high-risk populations, recognizing variability in clinical presentation in these high-risk populations, and including Doppler echocardiography as a tool to diagnose cardiac involvement.
