Process evaluation of a data-driven quality improvement program within a cluster randomised controlled trial to improve coronary heart disease management in Australian primary care.

BACKGROUND: This study evaluates primary care practices' engagement with various features of a quality improvement (QI) intervention for patients with coronary heart disease (CHD) in four Australian states. METHODS: Twenty-seven practices participated in the QI intervention from November 2019 -November 2020. A combination of surveys, semi-structured interviews and other materials within the QUality improvement in primary care to prevent hospitalisations and improve Effectiveness and efficiency of care for people Living with heart disease (QUEL) study were used in the process evaluation. Data were summarised using descriptive statistical and thematic analyses for 26 practices. RESULTS: Sixty-four practice team members and Primary Health Networks staff provided feedback, and nine of the 63 participants participated in the interviews. Seventy-eight percent (40/54) were either general practitioners or practice managers. Although 69% of the practices self-reported improvement in their management of heart disease, engagement with the intervention varied. Forty-two percent (11/26) of the practices attended five or more learning workshops, 69% (18/26) used Plan-Do-Study-Act cycles, and the median (Interquartile intervals) visits per practice to the online SharePoint site were 170 (146-252) visits. Qualitative data identified learning workshops and monthly feedback reports as the key features of the intervention. CONCLUSION: Practice engagement in a multi-featured data-driven QI intervention was common, with learning workshops and monthly feedback reports identified as the most useful features. A better understanding of these features will help influence future implementation of similar interventions.

Psychometric testing of the caregiver contribution to self-care of coronary heart disease inventory.

BACKGROUND: Caregivers are important contributors to the self-care of patients with coronary heart disease (CHD). AIMS: The aims of this study are to describe the development and psychometric properties of the caregiver contribution to self-care of coronary heart disease inventory (CC-SC-CHDI). METHODS: The CC-SC-CHDI was developed from the patient version of the scale, the Self-care of Coronary Heart Disease Inventory (SC-CHDI) and translated into Italian using forward and backward translation. Baseline data from the HEARTS-IN-DYADS study were used. Confirmatory factor analysis (CFA) was conducted to assess factorial validity; Cronbach's alpha and the model-based internal consistency index were used to test internal consistency reliability, and Pearson's correlation coefficient was used to test convergent validity, by investigating the association between the CC-SC-CHDI and the SC-CHDI scores. RESULTS: We included 131 caregivers (mean age 55 years, 81.2% females, 74% married) of patients affected by CHD (mean age 66 years, 80.2% males, 74% married). The CFA confirmed two factors in the caregiver contribution to self-care maintenance scale ("consulting behaviors" and "autonomous behaviors"), one factor for the CC to self-care monitoring scale, and two factors in the CC to self-care management scale ("consulting behaviors and problem-solving behaviors"). Reliability estimates were adequate for each scale (Cronbach's alpha and model-based internal consistency indexes ranging from 0.73 to 0.90). Significant and positive correlations were observed between CC-SC-CHDI and SC-CHDI scales. CONCLUSION: The CC-SC-CHDI has satisfactory validity and reliability and can be used confidently in clinical settings and research to assess caregiver contributions to CHD self-care.

The ABCs of the 2023 AHA/ACC/ACCP/ASPC/NLA/PCNA guideline for the management of patients with chronic coronary disease.

BACKGROUND: The 2023 Multisociety Guideline for the Management of Chronic Coronary Disease (CCD) updates recommendations for CCD, formerly known as "stable ischemic heart disease." This condition encompasses a spectrum of coronary vascular pathologies from subclinical to clinical ischemic heart disease. HYPOTHESIS: The new "ABC" mnemonic offers clinicians a streamlined framework for applying Class One Recommendations (COR1) and integrating recent updates into CCD management. METHODS: A critical analysis of the 2023 CCD guidelines was conducted, with this review highlighting key elements. RESULTS: The review outlines crucial changes, including novel recommendations supported by current clinical evidence. The focus is on these developments, clarifying their importance for day-to-day clinical practice. CONCLUSIONS: The review encourages a synergistic approach between primary healthcare providers and cardiologists to develop comprehensive strategies for lifestyle modification and medication therapy in CCD care. Furthermore, it suggests that utilizing comprehensive risk assessment tools can refine medical decision-making, ultimately enhancing patient care and clinical outcomes.

Development and implementation of a treatment pathway to reduce coronary angiograms - lessons from a failure.

BACKGROUND: The rates of coronary angiograms (CA) and related procedures (percutaneous intervention [PCI]) are significantly higher in Germany than in other Organisation for Economic Co-ordination and Development (OECD) countries. The current guidelines recommend non-invasive diagnosis of coronary heart disease (CHD); CA should only have a limited role in choosing the appropriate revascularisation procedure. The aim of the present study was to explore whether improvements in guideline adherence can be achieved through the implementation of regional treatment pathways. We chose four regions of Germany with high utilisation of CAs for the study. Here we report the results of the concomitant qualitative study. METHODS: General practitioners and specialist physicians (cardiologists, hospital-based cardiologists, emergency physicians, radiologists and nuclear medicine specialists) caring for patients with suspected CHD were invited to develop regional treatment pathways. Four academic departments provided support for moderation, provision of materials, etc. The study team observed session discussions and took notes. After the development of the treatment pathways, 45 semi-structured interviews were conducted with the participating physicians. Interviews and field notes were transcribed verbatim and underwent qualitative content analysis. RESULTS: Pathway development received little support among the participants. Although consensus documents were produced, the results were unlikely to improve practice. The participants expressed very little commitment to change. Although this attempt clearly failed in all study regions, our experience provides relevant insights into the process of evidence appraisal and implementation. A lack of organisational skills, ignorance of current evidence and guidelines, and a lack of feedback regarding one's own clinical behaviour proved to be insurmountable. CA was still seen as the diagnostic gold standard by most interviewees. CONCLUSIONS: Oversupply and overutilisation can be assumed to be present in study regions but are not immediately perceived by clinicians. The problem is unlikely to be solved by regional collaborative initiatives; optimised resource planning within the health care system combined with appropriate economic incentives might best address these issues.

[Application and Effect of Patient Portal System in the Remote Management of Chronic Diseases for Older Adults With Coronary Heart Disease]. / æ‚£è€ é—¨æˆ·ç³»ç»Ÿåœ¨è€å¹´å† å¿ƒç— æ ¢ç— è¿œç¨‹ç®¡ç†ä¸­çš„åº”ç”¨åŠæ•ˆæžœ.

Objective: To investigate the application of personal health record (PHR) and chronic disease management platform established on the basis of patient portal system (PPS) in managing older adults with coronary heart disease and to examine the effect on patients' self-care ability, coping mode, and quality of life. Methods: A total of 532 elderly patients with coronary heart disease were included in the study. All the participants enrolled were admitted to a tertiary-care hospital between January 2019 and June 2021. They were randomly assigned to the study group (269 cases) and the control group (263 cases). Patients in the control group were discharged with the routine discharge procedures and received the routine follow-up care. On the other hand, patients in the study group were discharged and followed up through the PHR and chronic disease management platform established on the basis of PPS. After 6 months, 12 months, and 18 months of patient management, the Exercise of Self-Care Agency (ESCA) Scale, Medical Coping Modes Questionnaire (MCMQ) and Seattle Angina Questionnaire (SAQ) were used to evaluate the patients' self-care ability, coping mode, and quality of life, respectively. The patient management effects of the two groups were analyzed. Results: Before the management programs started, there was no statistically significant difference in the scores for the scales between the two groups of patients. After 6 months, 12 months, and 18 months of patient management, the ESCA scores of both groups were higher than those before patient management started (P<0.05). Facing scores in the MCMQ of both groups were higher than those before patient management started (P<0.05), while the scores for avoidance and yielding were lower than those before patient management started (P<0.05). The SAQ scores of both groups were higher than those before patient management started (P<0.05). After 6 months, 12 months and 18 months of patient management, the ESCA scores of the study group were always higher compared with those of the control group (P<0.05). The facing score of the study group was higher, while the scores for avoidance and yielding were lower compared with those of the control group (P<0.05). The SAQ scores of the study group were higher compared with those of the control group (P<0.05). The medication compliance rate in the study group (83.27%) was higher than that in the control group (69.96%) (P<0.05). The incidence of adverse cardiovascular events in the study group (4.09%) was lower than that in the control group (10.27%) (P<0.05). The average times of emergency treatment and readmission in the study group were lower compared with those of the control group (P<0.05). The patient satisfaction score of the study group was higher compared with that of the control group (P<0.05). Conclusion: The PHR and chronic disease management platform established on the basis of PPS can increase the convenient access to medical care among elderly patients with coronary heart disease, which is conducive to improving their self-care ability, coping mode, and quality of life. In addition, the patient management effect is good.

Chronic Coronary Disease in Older Adults.

The number of older adults age ≥75 with chronic coronary disease (CCD) continues to rise. CCD is a major contributor to morbidity, mortality, and disability in older adults. Older adults are underrepresented in randomized controlled trials of CCD, which limits generalizability to older adults living with multiple chronic conditions and geriatric syndromes. This review discusses the presentation of CCD in older adults, reviews the guideline-directed medical and invasive therapies, and recommends a patient-centric approach to making treatment decisions.

Racial and Ethnic Disparities in the Management of Chronic Coronary Disease.

Chronic coronary disease (CCD) comprises a continuum of conditions that include obstructive and non-obstructive coronary artery disease with or without prior acute coronary syndrome. Racial and ethnic representation disparities are pervasive in CCD guideline-informing clinical trials and evidence-based management. These disparities manifest across the entire spectrum of CCD management, spanning from non-pharmacological lifestyle changes to guideline-directed medical therapy, and cardiac rehabilitation to invasive procedures. Recognizing and addressing the historical factors underlying these disparities is crucial for enhancing the quality and equity of CCD management within an increasingly diverse population.

Post-discharge nutritional management for patients with coronary heart disease and frailty: a qualitative study.

BACKGROUND: Frail elderly patients experience physiological function and reserve depletion, leading to imbalances in their internal environment, which increases the risk of coronary heart disease recurrence and malnutrition. However, the majority of these patients, who primarily have a low level of education and lack self-management skills, face difficulties actively dealing with obstacles during the transition period after their discharge from hospitalization. Therefore, it is necessary to understand and discuss in depth the nutrition management experience of discharged elderly patients with coronary heart disease and frailty (ages 65-80 years old) and to analyze the promoting and hindering factors that affect scientific diet behavior during the discharge transition period. METHODS: Fifteen elderly patients with coronary heart disease and frailty who had been discharged from the hospital for 6 months were interviewed using a semistructured method. The directed content analysis approach to descriptive research was used to extract topics from the interview content. RESULTS: All participants discussed the problems in health nutrition management experience of discharged. Five topics and ten subtopics were extracted, such as ①Weak perceptions and behaviors towards healthy eating (personal habit solidification, negative attitudes towards nutrition management), ②Lack of objective factors for independently adjusting dietary conditions (reliance on subjective feelings, times of appetite change), ③Personal hindrance factors (memory impairment, deficiencies in self-nutrition management), ④Expected external support (assistance care support, ways to obtain nutritional information), ⑤Lack of continuous nutrition management (interruption of professional guidance, avoidance of medical treatment behavior). CONCLUSIONS: Nutrition management after discharge places a burden on elderly patients with coronary heart disease and frailty. According to the patients' physical conditions, we should develop a diet support system that is coordinated by individuals, families and society.

Closing the sex gap in cardiovascular mortality by achieving both horizontal and vertical equity.

Addressing sex differences and disparities in coronary heart disease (CHD) involves achieving both horizontal and vertical equity in healthcare. Horizontal equity in the context of CHD means that both men and women with comparable health statuses should have equal access to diagnosis, treatment, and management of CHD. To achieve this, it is crucial to promote awareness among the general public about the signs and symptoms of CHD in both sexes, so that both women and men may seek timely medical attention. Women often face inequity in the treatment of cardiovascular disease. Current guidelines do not differ based on sex, but their applications based on gender do differ. Vertical equity means tailoring healthcare to allow equitable care for all. Steps towards achieving this include developing treatment protocols and guidelines that consider the unique aspects of CHD in women. It also requires implementing guidelines equally, when there is not sex difference rather than inequities in application of guideline directed care.

[General practitioners' perspectives on the perceived effectiveness of the disease management programs for type 2 diabetes and coronary heart disease: Results of a focus group study]. / Die wahrgenommene Effektivität der Disease Management Programme für Diabetes mellitus Typ 2 und Koronare Herzkrankheit aus Sicht von Hausärzt*innen ­ Ergebnisse einer Fokusgruppenstudie.

BACKGROUND: The majority of patients in disease management programs (DMPs) for type 2 diabetes (T2DM) and coronary heart disease (CHD) in Germany are enrolled by their general practitioner (GP). The aim of this study was, in the context of upcoming DMP expansions, to elicit GPs' current experiences and opinions regarding the perceived effectiveness and acceptance of the DMPs T2DM and CHD, as well as to determine beneficial and hindering aspects of the implementation of these programs from a GP's perspective. METHODS: In August and September 2020, 20 GPs of teaching practices of the University Hospital Cologne with experiences in DMPs were interviewed in semi-structured focus group discussions. Their expectations, attitudes and opinions regarding the DMPs T2DM and CHD were evaluated and analyzed according to the content-structuring qualitative content analysis by Kuckartz. RESULTS: The DMP T2DM was rated as generally positive by the respondents due to the structured treatment including regular foot and eye examinations, close patient contacts and perceptions of improved health outcomes. The DMP CHD was rated more negatively by the respondents because of a high and partly unnecessary documentation workload and limited therapeutic freedom, leading to a perceived ineffectiveness for patients' health outcomes. Thus, there was a discrepancy in the perceived effectiveness of the examined DMPs, causing a lower acceptance of the DMP CHD. Therefore, some of the respondents tended to enroll fewer patients into the DMP CHD or to drop out of the DMP CHD. DISCUSSION: In order to increase the acceptance and sustainability of DMPs some elements of the DMP CHD as well as the remuneration and the documentation need to be reconsidered. Additionally, future studies on the acceptance of DMPs should differentiate between different DMPs in order to generate valid results.

Nurse Practitioner Care Environments and Racial and Ethnic Disparities in Hospitalization Among Medicare Beneficiaries with Coronary Heart Disease.

BACKGROUND: Nurse practitioners care for patients with cardiovascular disease, particularly those from racial and ethnic minority groups, and can help assure equitable health outcomes. Yet, nurse practitioners practice in challenging care environments, which limits their ability to care for patients. OBJECTIVE: To determine whether primary care nurse practitioner care environments are associated with racial and ethnic disparities in hospitalizations among older adults with coronary heart disease. DESIGN: In this observational study, a cross-sectional survey was conducted among primary care nurse practitioners in 2018-2019 who completed a valid measure of care environment. The data was merged with 2018 Medicare claims data for patients with coronary heart disease. PARTICIPANTS: A total of 1244 primary care nurse practitioners and 180,216 Medicare beneficiaries 65 and older with coronary heart disease were included. MAIN MEASURES: All-cause and ambulatory care sensitive condition hospitalizations in 2018. KEY RESULTS: There were 50,233 hospitalizations, 9068 for ambulatory care sensitive conditions. About 28% of patients had at least one hospitalization. Hospitalizations varied by race, being highest among Black patients (33.5%). Care environment moderated the relationship between race (Black versus White) and hospitalization (OR 0.93; 95% CI, 0.88-0.98). The lowest care environment was associated with greater hospitalization among Black (odds ratio=1.34; 95% CI, 1.20-1.49) compared to White beneficiaries. Practices with the highest care environment had no racial differences in hospitalizations. There was no interaction effect between care environment and race for ambulatory care sensitive condition hospitalizations. Nurse practitioner care environment had a protective effect on these hospitalizations (OR, 0.96; 95% CI, 0.92-0.99) for all beneficiaries. CONCLUSIONS: Unfavorable care environments were associated with higher hospitalization rates among Black than among White beneficiaries with coronary heart disease. Racial disparities in hospitalization rates were not detected in practices with high-quality care environments, suggesting that improving nurse practitioner care environments could reduce racial disparities in hospitalizations.

Cell Therapy in the Treatment of Coronary Heart Disease.

Heart failure is a leading cause of death in patients who have suffered a myocardial infarction. Despite the timely use of modern reperfusion therapies such as thrombolysis, surgical revascularization and balloon angioplasty, they are sometimes unable to prevent the development of significant areas of myocardial damage and subsequent heart failure. Research efforts have focused on developing strategies to improve the functional status of myocardial injury areas. Consequently, the restoration of cardiac function using cell therapy is an exciting prospect. This review describes the characteristics of various cell types relevant to cellular cardiomyoplasty and presents findings from experimental and clinical studies investigating cell therapy for coronary heart disease. Cell delivery methods, optimal dosage and potential treatment mechanisms are discussed.

Efficacy and safety of different traditional Chinese health exercises in patients with coronary heart disease combined with chronic heart failure: A network meta-analysis.

BACKGROUND: Non-pharmacological treatments, particularly TCM health exercises, have garnered attention for their affordability, ease of access, and potential health advantages. Despite this interest, systematic and direct comparative studies assessing the effectiveness and safety of these therapies in patients with CHD-CHF remain scarce. METHODS: This study aimed to compare the efficacy and safety of conventional treatment, conventional treatment integrated with aerobic endurance training, and various TCM health exercises in treating patients with CHD-CHF using NMA. The analysis was designed to provide a reference for developing treatment plans. To achieve this, literature databases were searched for RCTs on different TCM health exercises for CHD-CHF patients up to December 6, 2022. Major outcomes analyzed included NT-proBNP, LVEF, 6-minute walk test, MLHFQ, clinical effectiveness, and adverse event occurrence. The Cochrane risk of bias tool was employed to assess the risk of bias in the included RCT studies. Systematic review with NMA was conducted using RevMan 5.4 and Stata for cumulative ranking, and comparative adjustment funnel plot analysis. RESULTS: Traditional Chinese medicine gong methods included BaDuanJin (A) and TaiChiQuan (B). The NMA and SUCRA results revealed that: A + D and A + C + D were most likely to be the best interventions to improve NT-proBNP; B + D and A + C + D were most likely to be the best interventions to improve LVEF; A + D and A + C + D were the best interventions to improve 6WMT in CHD-CHF patients; B + C + D had the best effect on shrinking LVESD;A + D and B + C + D was likely the best interventions for contracting LVEDD;B + D and A + D were consistent in their capacity to improve MLHFQ in patients with CHD-CHF, but B + D had better efficacy. Unlike A + C + D, B + C + D was the best intervention to improve MLHFQ. In contrast with interventions, including Dand C + D, B + D was the most clinically effective intervention. Unlike interventions including B + C + D, C + D, and D, A + C + D was the most clinically efficient intervention. CONCLUSION: The findings of this NMA showed that traditional Chinese health exercises integrated with conventional treatment are more effective than conventional treatment (D) alone in patients with CHD-CHF, with A + D, B + D, B + C + D, and A + C + D considered potentially optimal treatment interventions.

A Scoping Review of Predictors Associated with Self-Efficacy Among Patients with Coronary Heart Disease.

Self-efficacy (SE) is the main predictor of self-care behaviour in patients with coronary heart disease (CHD). Several studies identified factors that influence SE in CHD patients. However, review studies have yet to synthesize these results systematically. This review aims to identify SE and the factors influencing SE in CHD patients. This scoping review is reported based on the PRISMA Extension for Scoping Reviews (PRISMA-ScR). We searched using relevant keywords using five databases: CINAHL Plus with Full Text and Academic Search Complete, PubMed, ScienceDirect, Scopus, Taylor and Francis, and one search engine: Google Scholar, which was accessed on June 23, 2023. Articles with an observational design were included without date restrictions. The quality of evidence was assessed using the Joanna Briggs Institute critical appraisal checklist, and data synthesis used thematic analysis. We found 11 articles discussing SE and the factors influencing SE in CHD patients. In this review, most studies reported that the SE level of CHD patients tends to be low to moderate. Factors associated with SE in this population are classified into three categories (low, moderate, and high). Cardiac knowledge and patient activation are the most influential predictors of SE in CHD patients. Public health interventions such as raising awareness about heart disease, modifying health behaviours, early screening, diagnosis, and appropriate treatment are critical to improving SE and cardiac care outcomes.

The recent advances in cell delivery approaches, biochemical and engineering procedures of cell therapy applied to coronary heart disease.

Cell therapy is an important topic in the field of regeneration medicine that is gaining attention within the scientific community. However, its potential for treatment in coronary heart disease (CHD) has yet to be established. Several various strategies, types of cells, routes of distribution, and supporting procedures have been tried and refined to trigger heart rejuvenation in CHD. However, only a few of them result in a real considerable promise for clinical usage. In this review, we give an update on techniques and clinical studies of cell treatment as used to cure CHD that are now ongoing or have been completed in the previous five years. We also highlight the emerging efficacy of stem cell treatment for CHD. We specifically examine and comment on current breakthroughs in cell treatment applied to CHD, including the most effective types of cells, transport modalities, engineering, and biochemical approaches used in this context. We believe the current review will be helpful for the researcher to distill this information and design future studies to overcome the challenges faced by this revolutionary approach for CHD.

Application Effects of NNN-link Care Model in Patients with Coronary Heart Disease.

OBJECTIVE: To investigate the effect of a NNN-linked care model applied in elderly patients with coronary heart disease. METHODS: A total of 120 elderly patients with coronary heart disease admitted to the hospital from January, 2023 to May, 2023 were randomly divided into two groups of 60 cases respectively. The control group received routine intervention, and the observation group received the NNN-linked care model. Changes in cardiac function, the ability for self-care, and quality of life were recorded between the groups before and after the intervention. RESULTS: Indices of cardiac function in the observation group were higher than those of the control group after 3 weeks (p < 0.05). Compared with the control group, the total score for the ability for self-care and the scores of each dimension of the observation group were higher after 3 weeks of intervention (p < 0.05). The scores of quality of life of the observation group were higher in comparison with the control group after 3 weeks of intervention (p < 0.05). CONCLUSION: The application of the NNN-linked care model to elderly patients with coronary heart disease can improve the ability for self-care, increase cardiac function and improve the quality of life.

Impact of capitation prepayment on the medical expenses and health service utilization of patients with coronary heart disease: a community policy intervention program in a county in China.

BACKGROUND: Medical costs have been rising rapidly in recent years, and China is controlling medical costs from the perspective of health insurance payments. OBJECTIVES: To explore the impact of the capitation prepayment method on medical expenses and health service utilization of coronary heart disease (CHD) patients, which provides a scientific basis for further improvement of the payment approach. METHODS: The diagnosis records of visits for CHD in the database from 2014 to 2016 (April to December each year) were selected, and two townships were randomly selected as the pilot and control groups. Propensity score matching (PSM) and difference-in-difference (DID) model were used to assess changes in outpatient and inpatient expenses and health service utilization among CHD patients after the implementation of the capitation prepayment policy. RESULTS: There were eventually 3,900 outpatients and 664 inpatients enrolled in this study after PSM. The DID model showed that in the first year of implementing the reform, total outpatient expenses decreased by CNY 13.953, drug expenses decreased by CNY 11.289, as well as Medicare payments decreased by CNY 8.707 in the pilot group compared to the control group. In the second year of implementing the reform, compared with the control group, the pilot group had a reduction of CNY 3.123 in other expenses, and a reduction of CNY 6.841 in Medicare payments. There was no significant change in inpatient expenses in the pilot group compared to the control group, but there was an increase of 0.829 visits to rural medical institutions, and an increase of 0.750 visits within the county for inpatients. CONCLUSIONS: The capitation prepayment method has been effective in controlling the outpatient expenses of CHD patients, as well as improving the medical service capacity of medical institutions within the Medical Community, and increasing the rate of inside county visits for inpatients.

Prognosis of coronary heart disease after percutaneous coronary intervention: a bibliometric analysis over the period 2004-2022.

BACKGROUND: As the complexity and diversity of the percutaneous coronary intervention (PCI) are being explored and reported, burgeoning research has progressed in this field. However, there is no comprehensive analysis available on PCI-related studies published in the literature. This study aimed to analyze and visualize the changes of scientific output regarding prognosis of coronary heart disease (CHD) after PCI over the past 20 years and to reveal the knowledge domain and development trends in this field by using CiteSpace software. METHODS: Relevant articles published over the period 2004-2022 were retrieved from the Web of Science Core Collection database. After manual selection, qualified documents were included and recorded with the information of their title, abstract, keyword, author, descriptor, citation, identifier, publishing year and publishing organization. We transferred the data to CiteSpace V5.8.R2 (Version 5.8.R2) to draw knowledge maps and to conduct co-occurrence analysis, cluster analysis, timeline analysis, burst term detection and citation analysis. RESULTS: A total of 14,699 literature records were found relating prognosis of CHD after PCI in the past 20 years (2004-2022), including 14,212 original articles and reviews, and they were published in 153 different journals. Publication production has increased annually and a total of 1182 authors, 796 institutes and 147 countries have contributed to these publications. Moreover, the most representative author was Gregg W Stone from the CardioVascular Research Foundation (CVRF) with 368 publications, whose team mainly focused on exploring the efficacy and safety of revascularization and the characteristics of susceptible population. The global productivity ranking was led by the USA with 3326 published papers, followed by Italy (n = 1355), Japan (n = 1080), China (n = 1075) and Germany (n = 937). And the keywords of these publications were "percutaneous coronary intervention" (n = 2271), "outcome" (n = 1756), "mortality" (n = 1730) and "impact" (n = 1334). Other commonly-used words were "predictor" (n = 1324), "intervention" (n = 1310), "angioplasty" (n = 1299), "risk" (n = 1144), "acute myocardial infarction" (n = 1136) and "artery disease" (n = 1098). Cluster analysis showed that 15 high connected clusters were generated with a modularity Q of 0.831 and a weighted mean silhouette of 0.9388 by applying the log-likelihood ratio algorithm, and the top 5 clusters were #0 optical coherence tomography, #1 dual antiplatelet therapy, #2 bleeding, #3 clopidogrel and #4 thrombus aspiration. Furthermore, the frontiers in the field of prognosis of CHD after PCI mainly involved "decision making", "reperfusion", "angioplasty", "balloon", "unstable angina", "dual antiplatelet therapy", "cardiac surgical score", "restenosis", "reperfusion", "thrombolytic therapy", etc. CONCLUSIONS: To sum up, efficacy and safety of different types of stents, the risk factors of restenosis and thrombotic events after PCI, early risk assessment, and secondary prevention and complications of patients with CHD after PCI were research hotspots and frontier topics in the area by bibliometric analysis. The results could provide a comprehensive overview of the research hotspots and frontier topics relating prognosis of CHD after PCI, promoting a better understanding of the knowledge domain and development trends in this field during the past 20 years.
