Abstract
BACKGROUND Patients may prefer percutaneous coronary intervention (PCI) over coronary artery bypass graft (CABG) surgery, despite heart team recommendations. The outcomes in such patients have not been examined. We sought to examine the results of PCI in patients who were recommended for but declined CABG. METHODS AND RESULTS Consecutive patients with stable ischemic heart disease and unprotected left main or 3-vessel disease or Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery score >22 who underwent PCI after heart team review between 2013 and 2020 were included. Patients were categorized into 3 groups according to heart team recommendations on the basis of appropriate use criteria: (1) PCI-recommended; (2) CABG-eligible but refused CABG (CABG-refusal); and (3) CABG-ineligible. The primary end point was the composite of death, myocardial infarction, or stroke at 1 year. The study included 3687 patients undergoing PCI (PCI-recommended, n=1718 [46.6%]), CABG-refusal (n=1595 [43.3%]), and CABG-ineligible (n=374 [10.1%]). Clinical and procedural risk increased across the 3 groups, with the highest comorbidity burden in CABG-ineligible patients. Composite events within 1 year after PCI occurred in 55 (4.1%), 91 (7.0%), and 41 (14.8%) of patients in the PCI-recommended, CABG-refusal, and CABG-ineligible groups, respectively. After multivariable adjustment, the risk of the primary composite outcome was significantly higher in the CABG-refusal (hazard ratio [HR], 1.67 [95% CI, 1.08-3.56]; P=0.02) and CABG-ineligible patients (HR, 3.26 [95% CI, 1.28-3.65]; P=0.004) groups compared with the reference PCI-recommended group, driven by increased death and stroke. CONCLUSIONS Cardiovascular event rates after PCI were significantly higher in patients with multivessel disease who declined or were ineligible for CABG. Our findings provide real-world data to inform shared decision-making discussions.

Abstract
Importance Medical overutilization contributes to significant health care expenditures and exposes patients to questionably beneficial surgery and unnecessary risk. Objectives To understand public attitudes toward medical utilization and the association of these attitudes with beliefs about cancer. Design, Setting, and Participants In this cross-sectional survey study conducted from August 26 to October 28, 2020, US-based, English-speaking adults were recruited from the general public using Prolific Academic, a research participant platform. Quota-filling was used to obtain a sample demographically representative of the US population. Adults with a personal history of cancer other than nonmelanoma skin cancer were excluded. Statistical analysis was completed in July 2022. Main Outcome and Measures Medical utilization preferences were characterized with the validated, single-item Maximizer-Minimizer Elicitation Question. Participants preferring to take action in medically ambiguous situations (hereafter referred to as "maximizers") were compared with those who leaned toward waiting and seeing (hereafter referred to as "nonmaximizers"). Beliefs and emotions about cancer incidence, survivability, and preventability were assessed using validated measures. Logistic regression modeled factors associated with preferring to maximize medical utilization. Results Of 1131 participants (mean [SD] age, 45 [16] years; 568 women [50.2%]), 287 (25.4%) were classified as maximizers, and 844 (74.6%) were classified as nonmaximizers. Logistic regression revealed that self-reporting very good or excellent health status (compared with good, fair, or poor; odds ratio [OR], 2.01 [95% CI, 1.52-2.65]), Black race (compared with White race; OR, 1.88 [95% CI, 1.22-2.89]), high levels of cancer worry (compared with low levels; OR, 1.62 [95% CI, 1.09-2.42]), and overestimating cancer incidence (compared with accurate estimation or underestimating; OR, 1.58 [95% CI, 1.09-2.28]) were significantly associated with maximizing preferences. Those who believed that they personally had a higher-than-average risk of developing cancer were more likely to be maximizers (23.6% [59 of 250] vs 17.4% [131 of 751]; P = .03); this factor was not significant in regression analyses. Conclusions and Relevance In this survey study of US adults, those with medical maximizing tendencies more often overestimated the incidence of cancer and had higher levels of cancer-related worry. Targeted and personalized education about cancer and its risk factors may help reduce overutilization of oncologic care.

Quantifying lumen diameter in coronary artery stents with high-resolution photon counting detector CT and convolutional neural network denoising. Med Phys 2023; 50:4173-4181. [PMID: 37069830 PMCID: PMC10524296 DOI: 10.1002/mp.16415] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Revised: 03/07/2023] [Accepted: 03/30/2023] [Indexed: 04/19/2023] Open
Abstract
BACKGROUND Small coronary arteries containing stents pose a challenge in CT imaging due to metal-induced blooming artifact. High spatial resolution imaging capability is as the presence of highly attenuating materials limits noninvasive assessment of luminal patency. PURPOSE The purpose of this study was to quantify the effective lumen diameter within coronary stents using a clinical photon-counting-detector (PCD) CT in concert with a convolutional neural network (CNN) denoising algorithm, compared to an energy-integrating-detector (EID) CT system. METHODS Seven coronary stents of different materials and inner diameters between 3.43 and 4.72 mm were placed in plastic tubes of diameters 3.96-4.87 mm containing 20 mg/mL of iodine solution, mimicking stented contrast-enhanced coronary arteries. Tubes were placed parallel with or perpendicular to the scanner's z-axis in an anthropomorphic phantom emulating an average-sized patient and scanned with a clinical EID-CT and PCD-CT. EID scans were performed using our standard coronary computed tomography angiography (cCTA) protocol (120 kV, 180 quality reference mAs). PCD scans were performed using the ultra-high-resolution (UHR) mode (120 × 0.2 mm collimation) at 120 kV with tube current adjusted so that CTDIvol was matched to that of EID scans. EID images were reconstructed per our routine clinical protocol (Br40, 0.6 mm thickness), and with the sharpest available kernel (Br69). PCD images were reconstructed at a thickness of 0.6 mm and a dedicated sharp kernel (Br89) which is only possible with the PCD UHR mode. To address increased image noise introduced by the Br89 kernel, an image-based CNN denoising algorithm was applied to the PCD images of stents scanned parallel to the scanner's z-axis. Stents were segmented based on full-width half maximum thresholding and morphological operations, from which effective lumen diameter was calculated and compared to reference sizes measured with a caliper. RESULTS Substantial blooming artifacts were observed on EID Br40 images, resulting in larger stent struts and reduced lumen diameter (effective diameter underestimated by 41% and 47% for parallel and perpendicular orientations, respectively). Blooming artifacts were observed on EID Br69 images with 19% and 31% underestimation of lumen diameter compared to the caliper for parallel and perpendicular scans, respectively. Overall image quality was substantially improved on PCD, with higher spatial resolution and reduced blooming artifacts, resulting in the clearer delineation of stent struts. Effective lumen diameters were underestimated by 9% and 19% relative to the reference for parallel and perpendicular scans, respectively. CNN reduced image noise by about 50% on PCD images without impacting lumen quantification (<0.3% difference). CONCLUSION The PCD UHR mode improved in-stent lumen quantification for all seven stents as compared to EID images due to decreased blooming artifacts. Implementation of CNN denoising algorithms to PCD data substantially improved image quality.

Abstract
BACKGROUND Patients' perception of receiving overtreatment can cause distrust in medical services. Unlike outpatients, inpatients are highly likely to receive many medical services without fully understanding their medical situation. This information asymmetry could prompt inpatients to perceive treatment as excessive. This study tested the hypothesis that there are systematic patterns in inpatients' perceptions of overtreatment. METHODS We examined determinant factors of inpatients' perception of overtreatment in a cross-sectional design that used data from the 2017 Korean Health Panel (KHP), a nationally representative survey. For sensitivity analysis, the concept of overtreatment was analyzed by dividing it into a broad meaning (any overtreatment) and a narrow meaning (strict overtreatment). We performed chi-square for descriptive statistics, and multivariate logistic regression with sampling weights employing Andersen's behavioral model. RESULTS There were 1,742 inpatients from the KHP data set that were included in the analysis. Among them, 347 (19.9%) reported any overtreatment and 77 (4.42%) reported strict overtreatment. Furthermore, we found that the inpatient's perception of overtreatment was associated with gender, marital status, income level, chronic disease, subjective health status, health recovery, and general tertiary hospital. CONCLUSION Medical institutions should understand factors that contribute to inpatients' perception of overtreatment to mitigate patients' complaints due to information asymmetry. Moreover, based on the result of this study, government agencies, such as the Health Insurance Review and Assessment Service, should create policy-based controls and evaluate overtreatment behavior of the medical providers and intervene in the miscommunication between patients and providers.

Abstract
There is a variety of conduits utilized as vascular grafts in coronary artery bypass grafting (CABG). Post-CABG graft rate of failure varies depending on the type of conduit used, with the highest failure rates seen in saphenous vein grafts (SVG). Patency rates of SVG are reported to be about 75% at 12-18 months. Left internal mammary artery (LIMA) grafts have shown higher long-term patency rates when compared to other arterial and venous grafts; however, LIMA occlusions occur, most commonly in the early postoperative period. Percutaneous coronary intervention (PCI) of LIMA graft can be challenging based on the location, the length of the lesion, as well as other factors such as vessel tortuosity. Here we present a case of a complex intervention for osteal and proximal LIMA chronic total occlusion (CTO) in a symptomatic patient. Long stent delivery is usually a challenge in LIMA intervention; however, it was successfully achieved here by placing two overlapping stents. This intervention was also complicated by the tortuosity of the lesion, as well as the difficult cannulation of the left subclavian artery requiring a longer sheath for guide support.

Abstract
Background The indication for transcatheter aortic valve replacement (TAVR) for aortic stenosis (AS) significantly varies among physicians and institutions. Objectives This study aims to develop a set of appropriate use criteria for AS management to assist physicians in decision-making. Methods The RAND-modified Delphi panel method was used. A total of >250 common clinical scenarios were identified in terms of whether to perform the intervention for AS and the mode of intervention (surgical aortic valve replacement vs TAVR). Eleven nationally representative expert panelists independently rated the clinical scenario appropriateness on a scale of 1-9, as "appropriate" (7-9), "may be appropriate" (4-6), or "rarely appropriate" (1-3); the median score of the 11 experts was then assigned to an appropriate-use category. Results The panel identified 3 factors that were associated with a rarely appropriate rating in terms of performing the intervention: 1) limited life expectancy; 2) frailty; and 3) pseudo-severe AS on dobutamine stress echocardiography. Clinical scenarios that were deemed rarely appropriate for TAVR were also identified: 1) patients with low surgical risk and high TAVR procedural risk; 2) patients with coexistent severe primary mitral regurgitation or rheumatic mitral stenosis; and 3) bicuspid aortic valve that was not suitable for TAVR. Importantly, any TAVRs for patients who were older than 75 years of age were not rated as rarely appropriate. Conclusions These appropriate use criteria provide a practical guide for physicians regarding clinical situations commonly encountered in daily practice and elucidates scenarios deemed rarely appropriate that are clinical challenges for TAVR.

Contemporary Management Before Chronic Total Occlusion Percutaneous Coronary Interventions: Insights From the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program.

Abstract
BACKGROUND Guidelines recommend maximal antianginal medical therapy before attempted coronary artery chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The degree to which this occurs in contemporary practice is unknown. We aimed to characterize the frequency and variability of preprocedural use of antianginal therapy and stress testing within 3 months before PCI of CTO (CTO PCI) across a nationally integrated health care system. METHODS We identified patients who underwent attempted CTO PCI from January 2012 to September 2018 within the Veterans Affairs Healthcare System. Patients were categorized by management before CTO PCI: presence of ≥2 antianginals, stress testing, and ≥2 antianginals and stress testing within 3 months of PCI attempt. Multivariable logistic regression and inverse propensity weighting were used for adjustment before trimming, with median odds ratios calculated for variability estimates. RESULTS Among 4250 patients undergoing attempted CTO PCI, 40% received ≥2 antianginal medications and 24% underwent preprocedural stress testing. The odds of antianginal therapy with more than one medication before CTO PCI did not change over the years of the study (odds ratio [OR], 1.0 [95% CI, 0.97-1.04]), whereas the odds of undergoing preprocedural stress testing decreased (OR, 0.97 [95% CI, 0.93-0.99]), and the odds of antianginal therapy with ≥2 antianginals and stress testing did not change (OR, 0.98 [95% CI, 0.93-1.04]). Median odds ratios (MOR) showed substantial variability in antianginal therapy across hospital sites (MOR, 1.3 [95% CI, 1.26-1.42]) and operators (MOR, 1.35 [95% CI, 1.26-1.63]). Similarly, preprocedural stress testing varied significantly by site (MOR, 1.68 [95% CI, 1.58-1.81]) and operator (MOR, 1.80 [95% CI, 1.56-2.38]). CONCLUSIONS Just under half of patients received guideline-recommended management before CTO PCI, with significant site and operator variability. These findings suggest an opportunity to reduce variability in management before CTO PCI.

Abstract
Background
There are limited data about how COURAGE (Clinical Outcomes Utilizing Revascularization and Aggressive Drug Evaluation) and ORBITA (Objective Randomized Blinded Investigation With Optimal Medical Therapy of Angioplasty in Stable Angina) trials have impacted percutaneous coronary intervention (PCI) practices at regional or national level. We evaluated temporal trends in elective PCI rates for stable angina and, specifically, examined the impact of the COURAGE and ORBITA trials on PCI practices in England and Wales.
Methods and Results
We used national PCI data comprising >1.2 million patients undergoing PCI between January 2006 and December 2019. Patient demographics, procedural details, and clinical outcomes were analyzed, and temporal trends in PCI rates for stable angina were compared before and after the publication of the COURAGE and ORBITA trials. Of 1 245 802 PCI procedures, 430 248 (34.5%) were performed for stable angina. Over the study period, the number of elective PCI procedures per year (30 823 in 2006 to 34 103 in 2019) and per 100 000 population estimates (50.7 in 2006 to 58.4 in 2019) remained stable. The proportion of patients undergoing elective PCI without angina symptoms almost doubled from 5.1% to 9.7%. The incidence rate of elective PCI volume after the COURAGE trial, published in 2007, was not different from before the trial was published (incidence rate ratio, 1.06 [95% CI, 0.69–1.62]). It also remained stable after the publication of the ORBITA trial in 2017 (incidence rate ratio, 0.96 [95% CI, 0.74–1.23]).
Conclusions
In this nationwide analysis, rates of elective PCI for stable angina remained stable over 14 years. Publication of the COURAGE and ORBITA trials had no impact on elective PCI activity.

Formative Assessment of Diagnostic Testing in Family Medicine with Comprehensive MCQ Followed by Certainty-Based Mark. Healthcare (Basel) 2022; 10:healthcare10081558. [PMID: 36011215 PMCID: PMC9408718 DOI: 10.3390/healthcare10081558] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2022] [Revised: 07/29/2022] [Accepted: 08/14/2022] [Indexed: 11/25/2022] Open
Abstract
Introduction: The choice of diagnostic tests in front of a given clinical case is a major part of medical reasoning. Failure to prescribe the right test can lead to serious diagnostic errors. Furthermore, unnecessary medical tests are a waste of money and could possibly generate injuries to patients, especially in family medicine. Methods: In an effort to improve the training of our students to the choice of laboratory and imaging studies, we implemented a specific multiple-choice questions (MCQ), called comprehensive MCQ (cMCQ), with a fixed and high number of options matching various basic medical tests, followed by a certainty-based mark (CBM). This tool was used in the assessment of diagnostic test choice in various clinical cases of general practice in 456 sixth-year medical students. Results: The scores were significantly correlated with the traditional exams (standard MCQ), with matched themes. The proportion of “cMCQ/CBM score” variance explained by “standard MCQ score” was 21.3%. The cMCQ placed students in a situation closer to practice reality than standard MCQ. In addition to its usefulness as an assessment tool, those tests had a formative value and allowed students to work on their ability to measure their doubt/certainty in order to develop a reflexive approach, required for their future professional practice. Conclusion: cMCQ followed by CBM is a feasible and reliable evaluation method for the assessment of diagnostic testing.

Development and evaluation of the accuracy of an indicator of the appropriateness of interventional cardiology generated from a French registry. Arch Public Health 2022; 80:132. [PMID: 35524321 PMCID: PMC9077814 DOI: 10.1186/s13690-022-00885-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 04/25/2022] [Indexed: 11/13/2022] Open
Abstract
Background Development of appropriateness indicators of medical interventions has become a major quality-of-care issue, especially in the domain of interventional cardiology (IC). The objective of this study was to develop and evaluate the accuracy of an indicator of the appropriateness of interventional cardiology acts (invasive coronary angiographies (ICA) and percutaneous coronary interventions (PCI)) in patients with coronary stable disease and silent ischemia, automated from a French registry. Methods All ICA and PCI recorded in a Regional IC Registry (ACIRA) and operated for a stable coronary artery disease or silent ischemia from January 1st to December 31th 2013 in eight IC hospitals of Aquitaine, southwestern France, were included. The indicator was developed to reflect European guidelines. Classification of appropriateness by the indicator, measured on the registry database, was compared to the classification of a reference standard (expert judgment applied through complete record review) on a random sample of 300 interventions. Accuracy parameters were estimated. A second version of the indicator was defined, based on the analysis of false negative and positive results, and its accuracy estimated. Results The second indicator accuracy was: sensitivity 63.5% (95% confidence interval CI [51.7–75.3]), specificity 76.0% (95%CI [70.4–81.6]), PPV 43.0% (95% CI [33.0–53.0]) and NPV 88.0% (95% CI [83.4–92.6]). When stratified on the type of act, parameters were better for ICA alone than for PCI. Conclusions Accuracy of the indicator should raise with improvement of database quality. Despite its average accuracy, it is already used as a benchmark indicator for cardiologists. It is sent annually to each IC center with value of the indicator at the region level to allow a comparison.

Abstract
INTRODUCTION Overuse of cardiovascular healthcare services, defined as the provision of low-value (ineffective, harmful, cost-ineffective) tests, medications and procedures, may be common and associated with increased patient harm and health system inefficiencies and costs. We seek to systematically review the evidence for overuse of different cardiovascular healthcare services in high-income countries. METHODS AND ANALYSIS We will search MEDLINE, EMBASE and Evidence-Based Medicine Reviews from 2010 onwards. Two investigators will independently review titles and abstracts and full-text studies. We will include published English-language studies conducted in high-income countries that enrolled adults (mean/median age ≥18 years) and reported the incidence or prevalence of overuse of cardiovascular tests, medications or procedures; adjusted risk factors for overuse; or adjusted associations between overuse and outcomes (reported estimates of morbidity, mortality, costs or lengths of hospital stay). Acceptable methods of defining low-value care will include literature review and multidisciplinary iterative panel processes, healthcare services with reproducible evidence of a lack of benefit or harm, or clinical practice guideline or Choosing Wisely recommendations. Two investigators will independently extract data and evaluate study risk of bias in duplicate. We will calculate summary estimates of the incidence and prevalence of overuse of different cardiovascular healthcare services across studies unstratified and stratified by country; method of defining low-value care; the percentage of included females, different races, and those with low and high socioeconomic status or cardiovascular risk; and study risks of bias using random-effects models. We will also calculate pooled estimates of adjusted risk factors for overuse and adjusted associations between overuse and outcomes overall and stratified by country using random-effects models. We will use the Grading of Recommendations, Assessment, Development and Evaluation to determine certainty in estimates. ETHICS AND DISSEMINATION No ethics approval is required for this study as it deals with published data. Results will be presented at meetings and published in a peer-reviewed journal.

Abstract
Despite limited benefit, percutaneous coronary intervention (PCI) remains a common procedure that is often performed for uncertain or inappropriate indications in patients with stable coronary artery disease (CAD). PCI cases per capita have increased year-over-year in most European countries, and many have higher rates than the U.S. Meanwhile, first-line therapy such as optimal medical therapy (OMT) and lifestyle changes, continue to be under-utilized. This article reviews the evidence on use of PCI in stable CAD. Specifically, we analyzed randomized control trials, systematic reviews, appropriate use criteria, and professional society guidelines that examine the risks and benefits of PCI compared to OMT. We then highlight utilization patterns as well as interventions that better align current practice with evidence-based care.

Abstract
BACKGROUND The appropriateness of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions has rarely been investigated.Methods and Results:The Japanese CTO-PCI Expert Registry enrolled consecutive patients undergoing CTO-PCI carried out by highly experienced Japanese CTO specialists who performed more than 50 CTO-PCIs per year and 300 CTO-PCIs in total. This study included patients undergoing CTO-PCI between January 2014 and December 2019. The appropriateness, trends, and differences among the procedures performed by the operators using the 2017 appropriate use criteria were analyzed. Furthermore, we performed a logistic regression analysis to assess whether the appropriateness was associated with in-hospital major adverse cardiovascular and cerebrovascular events (MACCE). Of the 5,062 patients who underwent CTO-PCI, 4,309 (85.1%) patients who did not undergo the non-invasive stress test were classified as having no myocardial ischemia. Of the total cases, 3,150 (62.2%) were rated as "may be appropriate," and 642 (12.7%) as "rarely appropriate" CTO-PCI cases. The sensitivity analyses showed that the number (%) of "may be appropriate" ranged from 4,125 (57.8%) to 4,744 (66.4%) and the number of "rarely appropriate" ranged from 843 (11.8%) to 970 (13.6%) among best and worst scenarios. CONCLUSIONS In a large Japanese CTO-PCI registry, approximately 13% of CTO-PCI procedures were classified as "rarely appropriate". Substantial efforts would be required to decrease the number of "rarely appropriate" CTO-PCI procedures.

Abstract
Introduction Atherosclerotic coronary artery disease (CAD) is the major cause of mortality in the USA. CAD requiring percutaneous coronary intervention (PCI) can have a wide spectrum of presentations. We reviewed the cost of admission and PCI at the tertiary care center stratified for different CAD presentation types. Methods We performed a retrospective study of 7,389 patients undergoing coronary angiogram at our facility from 2015 to 2017. Patients were selected from CathPCI registry. Chart review was done for readmission and death data. Cost data were provided by the finance department. Patients going for coronary artery bypass surgery (CABG) were excluded. We split the patients based on their need for PCI. Cost analysis was based on CAD presentation types (No symptoms, atypical symptoms, stable angina, unstable angina, NSTEMI [non-ST segment elevation myocardial infarction], STEMI [ST-segment elevation myocardial infarction]). Adjusted linear regression was run for the outcomes. Primary outcomes were 30-day readmission and death. The secondary outcome was cost of admission. Results The final sample size was 6,403. The mean age was 65.6 years (SD: 12.5; male: 63.8%). 2444 required PCI (38%; p < 0.001). PCI group had lower mean age (62.5 years; SD: 12.3, p<0.001) with lower BMI (30.6 vs 31.1, p=0.015). PCI group had significantly lower odds for 30-day readmission (OR: 0.63; CI: 0.45-0.89; p=0.009) and 30-day mortality (OR:0.60; CI: 0.41-0.89; p = 0.011). A severe presentation increased the odds of getting PCI. Cost of admission was higher in all groups receiving PCI. Conclusions PCI group had better 30-day readmission and mortality rates. PCI increases the cost of admission in all CAD types.

Abstract
Objective The aim of the study was to apply the appropriate use criteria (AUC) for coronary revascularization on Russian Acute Coronary Syndrome Registry (RusACSR) data to analyze validity of the decision to perform percutaneous coronary interventions (PCIs) among patients with acute coronary syndrome (ACS). Material and Methods In Russia, the frequency of performing PCI increased almost 7.5 times, and more than half of all interventions were performed in patients with ACS, in the period from 2006 to 2015. AUC 2012 were used to assess PCI appropriateness. Data were exported from RusACSR from a period of January 1, 2016 to December 31, 2016. We analyzed 33 893 cases, but 13 957 patients were excluded owing to absence of data needed. The study group therefore included 19 936 patients with ACS (mean age, 65.3 ± 11.9 years; 40.3% women), and it was divided into 2 subgroups: 13 757 (67.2%) patients who were treated conservatively and 6179 (32.8%) patients who underwent PCI. According to AUC, physicians' choice of strategy was validated. Results Patients treated conservatively differed significantly (P < .001) from those who underwent PCI. In this group, non-ST segment elevation ACS was significantly more common than in the group of patients who received PCI (84.4% vs. 43.9%, P < .001). They also had more severe clinical status. According to AUC, among patients with ACS treated with PCI, the decision was warranted in 86.3% (valid decision). In 7.6% of cases, there was no need for PCI. Among patients who underwent conservative treatment, 77.7% of patients needed PCI according to AUC. According to our data, only 3.8% of patients who were treated conservatively did not need PCI. Appropriateness of invasive treatment was uncertain in 18.5% and 6.1% in the PCI and non-PCI groups, respectively. All differences were significant (P < .001). Conclusion AUC implementation showed low availability of PCI for patients with non-ST segment elevation ACS accompanied by complicated clinical status. AUC for coronary revascularization could be applied in Russian clinical practice for unbiased PCI candidate selection and for evaluation of decision validity.

Abstract
The aim of this study was to assess the appropriate use of diagnostic catheterizations (DC) for the patients with suspected coronary artery disease performed in Iran. The Electronic Health Record System database and manual review of files were utilised to collect data between 2012 and 2014. Patients were categorized in three groups as appropriate, uncertain, and inappropriate usage of DC and the logistic regression was used to investigate the relationships between variables. One-quarter of the 2458 angiographies were rated as inappropriate, out of which 99% had no previous stress test. The rate of inappropriate DC between various hospitals were approximately the same. The regression showed that some risk factors (Sex, high cholesterol, smoking, chronic heart failure, renal failure, diabetes) were significantly associated with inappropriate rate.

Yuan N, Boscardin C, Lisha NE, Dudley RA, Lin GA. Is Better Patient Knowledge Associated with Different Treatment Preferences? A Survey of Patients with Stable Coronary Artery Disease. Patient Prefer Adherence 2021; 15:119-126. [PMID: 33531798 PMCID: PMC7847412 DOI: 10.2147/ppa.s289398] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Accepted: 12/22/2020] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND In stable coronary artery disease (CAD), shared decision-making (SDM) is encouraged when deciding whether to pursue percutaneous coronary intervention (PCI) given similar cardiovascular outcomes between PCI and medical therapy. However, it remains unclear whether improving patient-provider communication and patient knowledge, the main tenets of SDM, changes patient preferences or the treatment chosen. We explored the relationships between patient-provider communication, patient knowledge, patient preferences, and the treatment received. METHODS We surveyed stable CAD patients referred for elective cardiac catheterization at seven hospitals from 6/2016 to 9/2018. Surveys assessed patient-provider communication, medical knowledge, and preferences for treatment and decision-making. We verified treatments received by chart review. We used linear and logistic regression to examine relationships between patient-provider communication and knowledge, knowledge and preference, and preference and treatment received. RESULTS Eighty-seven patients completed the survey. More discussion of the benefits and risks of both medical therapy and PCI associated with higher patient knowledge scores (β=0.28, p<0.01). Patient knowledge level was not associated with preference for PCI (OR=0.78, 95% CI 0.57-1.03, p=0.09). Black patients had more than four times the odds of preferring medical therapy to PCI (OR=4.49, 1.22-18.45, p=0.03). Patients preferring medical therapy were not significantly less likely to receive PCI (OR=0.67, 0.16-2.52, p=0.57). CONCLUSIONS While communicating the risks of PCI may improve patient knowledge, this knowledge may not affect patient treatment preferences. Rather, other factors such as race may be significantly more influential on a patient's treatment preferences. Furthermore, patient preferences are still not well reflected in the treatment received. Improving shared decision-making in stable CAD therefore may require not only increasing patient education but also better understanding and including a patient's background and pre-existing beliefs.

The risk for subsequent coronary interventions in a local Polish population. ADVANCES IN INTERVENTIONAL CARDIOLOGY 2020; 16:429-435.

Abstract
Introduction Paradoxically, the literature lacks an assessment of the impact of various factors on subsequent coronary interventions in patients with coronary artery disease (CAD). Aim To assess the impact of various factors on subsequent percutaneous transluminal coronary angioplasty (PTCA), as well as to characterize the clinical profile of people undergoing repeated diagnostic coronary angiography without significant coronary artery changes. Material and methods We investigated retrospective data from 4041 subjects according to the clinical factors which may affect the occurrence of unplanned future PTCA. Results The strongest risk factors for subsequent PTCA were significant stenosis of left descending artery (OR = 2.17, 95% CI: 1.09–4.32) during baseline coronary angiography, the atherosclerotic burden (number of critically narrowed vessels) (OR for narrowing lesions in 3 epicardial arteries 12.13, 95% CI: 5.40–27.27), and restenosis in a previously implanted stent (OR = 4.34, 95% CI: 1.96–9.62). A strong positive relationship between total mortality and the number of critically narrowed coronary arteries (during baseline hospitalization) was observed. Patients without significant coronary artery stenosis in two diagnostic angiographies (control group) differed from subjects with hemodynamic relevant CAD in: higher creatinine levels, more frequent presence of chronic obstructive pulmonary disease and more frequent symptoms of intermittent claudication. Conclusions The results of the study are in accord with real clinical practice. The arteriosclerotic burden is a major cause of recurrent PTCA, but an important clinical issue is the qualification for recurrent coronary-angiography in those patients whose previous coronary angiography did not show significant stenosis, because other clinical causes may explain their symptoms.

Abstract
Smart materials have intrinsic properties that change in a controlled fashion in response to external stimuli. Currently, the only smart materials with a significant clinical impact in cardiovascular implant design are shape memory alloys, particularly Nitinol. Recent prodigious progress in material science has resulted in the development of sophisticated shape memory polymers. In this article, we have reviewed the literature and outline the characteristics, advantages, and disadvantages of shape memory alloys and shape memory polymers which are relevant to clinical cardiovascular applications, and describe the potential of these smart materials for applications in coronary stents and transcatheter valves.

J Eval Clin Pract 2020; 26:1711-1721. [PMID: 31994280 PMCID: PMC7552995 DOI: 10.1111/jep.13341] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2019] [Revised: 11/28/2019] [Accepted: 11/29/2019] [Indexed: 01/09/2023]
Abstract
RATIONALE, AIMS, AND OBJECTIVES Clinical studies show equivalent health outcomes from interventional procedures and treatment with medication only for stable angina patients. However, patients may be subject to overuse or access barriers for interventional procedures and may exhibit suboptimal adherence to medications. Our objective is to evaluate whether community-level health literacy is associated with treatment selection and medication adherence patterns. METHOD The sample included Medicare fee-for-service beneficiaries (20% random sample) with stable angina in 2007-2013. We used an area-level health literacy variable because of the lack of an individual measure in claims. We measured the association between (a) area-based health literacy with treatment selection (medication only, percutaneous coronary intervention [PCI], or coronary artery bypass grafting (CABG) surgery) and (b) area-based health literacy with medication adherence. We controlled for other factors including demographics, co-morbidity burden, dual eligibility, and area deprivation index. RESULTS We identified 8300 patients of whom 8.7% lived in a low health literacy area. Overall, 56% of patients received medication only, 28% received PCI, and 15% received CABG. Patients in low health literacy areas were less likely to receive CABG (-3.5 percentage points; 95% CI, -6.8 to -0.3) than were patients in high health literacy areas, but the significance was sensitive to specification. Overall, 81.5% and 71.5% of patients were adherent to antianginals and statins, respectively. Living in low health literacy areas was associated with lower adherence to antianginals (-3.3 percentage points; 95% CI, -6.1 to -0.6) but not statins. CONCLUSIONS Low area-based health literacy was associated with being less likely to receive CABG and lower adherence, but the differences between low and high health literacy areas were small and sensitive to model specification. Individual factors such as dual eligibility status and race/ethnicity had stronger associations with outcomes than had area-based health literacy, suggesting that this area-based measure was inadequate to account for social determinants in this study.

Abstract
Cardiovascular diseases are still among the first causes of death worldwide with a huge impact on healthcare systems. Within these conditions, the correct diagnosis of coronary artery disease with the most appropriate imaging-based evaluations is of utmost importance. The sustainability of the healthcare systems, considering the high economic burden of modern cardiac imaging equipments, makes cost-effective analysis an important tool, currently used for weighing different costs and health outcomes, when policy makers have to allocate funds and to prioritize interventions, getting the most out of their financial resources. This review aims at evaluating cost-effective analysis in the more recent literature, focused on the role of Calcium Score, coronary computed tomography angiography and cardiac magnetic resonance.

Abstract
BACKGROUND Elective percutaneous coronary interventions (PCI) are difficult to discriminate from non-elective PCI in administrative data due to non-specific encounter codes, limiting the ability to track outcomes, ensure appropriate medical management, and/or perform research on patients who undergo elective PCI. The objective of this study was to assess the abilities of several algorithms to identify elective PCI procedures using administrative data containing diagnostic, utilization, and/or procedural codes. METHODS AND RESULTS For this retrospective study, administrative databases in an integrated healthcare delivery system were queried between 1/1/2015 and 6/31/2016 to identify patients who had an encounter for a PCI. Using clinical criteria, each encounter was classified via chart review as a valid PCI, then as elective or non-elective. Cases were tested against nine pre-determined algorithms. Performance statistics (sensitivity, specificity, positive predictive value, and negative predictive value) and associated 95% confidence intervals (CI) were calculated. Of 521 PCI encounters reviewed, 497 were valid PCI, 93 of which were elective. An algorithm that excluded emergency room visit events had the highest sensitivity (97.9%, 95%CI 92.5%-99.7%) while an algorithm that included events occurring within 90 days of a cardiologist visit and coronary angiogram or stress test had the highest positive predictive value (62.2%, 95%CI 50.8%-72.7%). CONCLUSIONS Without an encounter code specific for elective PCI, an algorithm excluding procedures associated with an emergency room visit had the highest sensitivity to identify elective PCI. This offers a reasonable approach to identify elective PCI from administrative data.

Abstract
IMPORTANCE In hospitals outside of the US Department of Veterans Affairs (VA) system, 1 in 10 percutaneous coronary interventions (PCIs) for stable coronary artery disease is considered rarely appropriate by the appropriate use criteria, with variation across hospitals. The appropriateness of PCIs in VA hospitals has not been documented. OBJECTIVE To characterize the appropriateness of PCIs in VA hospitals. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study included patients with stable coronary artery disease undergoing elective PCI from November 1, 2013, to October 31, 2015, within the VA Clinical Assessment, Reporting, and Tracking Program, an operational program that includes 59 VA hospitals. Data were analyzed from March 1, 2019, to August 8, 2019. EXPOSURES Elective PCI at a VA hospital. MAIN OUTCOMES AND MEASURES Proportion of PCIs classified as appropriate, may be appropriate, or rarely appropriate; extent of hospital-level variation in rarely appropriate PCIs using criteria issued by cardiovascular professional societies in 2012. The extent of hospital-level variation in rates of rarely appropriate PCI was characterized using hospital proportions and random-effect logistic regression. RESULTS Among 2611 patients undergoing elective PCI (mean [SD] age, 66.3 [7.6] years; 2577 [98.7%] men) at 59 hospitals, a total of 778 PCIs (29.8%) were classified as appropriate, 1561 PCIs (59.8%) were classified as may be appropriate, and 272 PCIs (10.4%) were classified as rarely appropriate. Rarely appropriate PCIs were more commonly performed in patients who had low-risk stress test findings (220 patients [89.1%]), who were taking no (100 patients [36.8%]) or 1 (167 patients [61.4%]) antianginal medication, or who had 1 coronary artery stenosis (185 patients [68.0%]). The unadjusted hospital-level rates of rarely appropriate PCIs ranged from 0% to 28.6%, with a median (interquartile range) of 9.7% (6.3%-13.9%). Random-effect models yielded an estimated median (interquartile range) rate of rarely appropriate PCI of 10.4% (8.7%-12.3%). CONCLUSIONS AND RELEVANCE These findings suggest that in VA practice, most PCIs for stable coronary artery disease were classified as appropriate or may be appropriate. However, 1 in 10 PCIs was classified as rarely appropriate, with variation across VA hospitals. Efforts to improve patient selection are needed.

Abstract
BACKGROUND Percutaneous coronary intervention is a common revascularisation technique. Serious complications are uncommon, but death is one of them. Seeking informed consent in advance of percutaneous coronary intervention is mandatory. Research shows that percutaneous coronary intervention patients have inaccurate perceptions of risks, benefits and alternative treatments. AIM To assess cardiologists' and patients' views about the informed consent process and anticipated treatment benefits. METHODS Two cross-sectional, anonymous surveys were distributed in England: an electronic version to a sample of cardiologists and a paper-based version to patients recruited from 10 centres. RESULTS A sample of 118 cardiologists and 326 patients completed the surveys. Cardiologists and patients shared similar views on the purpose of informed consent; however, over 40% of patients and over a third of cardiologists agreed with statements that patients do not understand, or remember, the information given to them. Patients placed less value than cardiologists on the consent process and over 60% agreed that patients depended on their doctor to make the decision for them. Patients' and cardiologists' views on the benefits of percutaneous coronary intervention were significantly different; notably, 60% of patients mistakenly believed that percutaneous coronary intervention was curative. CONCLUSIONS The percutaneous coronary intervention informed consent process requires improvement to ensure that patients are more involved and accurately understand treatment benefits to make an informed decision. Redesign of the patient pathway is recommended to allow protected time for health professionals to engage in discussions using evidence-based approaches such as 'teach back' and decision support which improve patient comprehension.

Abstract
BACKGROUND Although many studies show an inverse association between operator procedural volume and short-term adverse outcomes after percutaneous coronary intervention (PCI), the association between procedural volume and longer-term outcomes is unknown. METHODS Using the National Cardiovascular Data Registry CathPCI registry data linked with Medicare claims data, we examined the association between operator PCI volume and long-term outcomes among patients ≥65 years of age. Operators were stratified by average annual PCI volume (counting PCIs performed in patients of all ages): low- (<50 PCIs), intermediate- (50-100), and high- (>100) volume operators. One-year unadjusted rates of death and major adverse coronary events (MACEs; defined as death, readmission for myocardial infarction, or unplanned coronary revascularization) were calculated with Kaplan-Meier methods. The proportional hazards assumption was not met, and risk-adjusted associations between operator volume and outcomes were calculated separately from the time of PCI to hospital discharge and from hospital discharge to 1-year follow-up. RESULTS Between July 1, 2009, and December 31, 2014, 723 644 PCI procedures were performed by 8936 operators: 2553 high-, 2878 intermediate-, and 3505 low-volume operators. Compared with high- and intermediate-volume operators, low-volume operators more often performed emergency PCI, and their patients had fewer cardiovascular comorbidities. Over 1-year follow-up, 15.9% of patients treated by low-volume operators had a MACE compared with 16.9% of patients treated by high-volume operators ( P=0.004). After multivariable adjustment, intermediate- and high-volume operators had a significantly lower rate of in-hospital death than low-volume operators (odds ratio, 0.91; 95% CI, 0.86-0.96 for intermediate versus low; odds ratio, 0.79; 95% CI, 0.75-0.83 for high versus low). There were no significant differences in rates of MACEs, death, myocardial infarction, or unplanned revascularization between operator cohorts from hospital discharge to 1-year follow-up (adjusted hazard ratio for MACEs, 0.99; 95% CI, 0.96-1.01 for intermediate versus low; hazard ratio, 1.01; 95% CI, 0.99-1.04 for high versus low). CONCLUSIONS Unadjusted 1-year outcomes after PCI were worse for older adults treated by operators with higher annual volume; however, patients treated by these operators had more cardiovascular comorbidities. After risk adjustment, higher operator volume was associated with lower in-hospital mortality and no difference in postdischarge MACEs.

Abstract
Importance Physicians often report practicing defensive medicine to reduce malpractice risk, including performing expensive but marginally beneficial tests and procedures. Although there is little evidence that malpractice reform affects overall health care spending, it may influence physician behavior for specific conditions involving clinical uncertainty. Objective To examine whether reducing malpractice risk is associated with clinical decisions involving coronary artery disease testing and treatment. Design, Setting, and Participants Difference-in-differences design, comparing physician-specific changes in coronary artery disease testing and treatment in 9 new-cap states that adopted damage caps between 2003 and 2005 with 20 states without caps. We used the 5% national Medicare fee-for-service random sample between 1999 and 2013. Physicians (n = 75 801; 36 647 in new-cap states) who ordered or performed 2 or more coronary angiographies. Data were analyzed from June 2015 to January 2018. Main Outcomes and Measures Changes in ischemic evaluation rates for possible coronary artery disease, type of initial evaluation (stress testing or coronary angiography), progression from stress test to angiography, and progression from ischemic evaluation to revascularization (percutaneous coronary intervention or coronary artery bypass grafting). Results We studied 36 647 physicians in new-cap states and 39 154 physicians in no-cap states. New-cap states had younger populations, more minorities, lower per-capita incomes, fewer physicians per capita, and lower managed care penetration. Following cap adoption, new-cap physicians reduced invasive testing (angiography) as a first diagnostic test compared with control physicians (relative change, -24%; 95% CI, -40% to -7%; P = .005) with an offsetting increase in noninvasive stress testing (7.8%; 95% CI, -3.6% to 19.3%; P = .17), and referred fewer patients for angiography following stress testing (-21%; 95% CI, -40% to -2%; P = .03). New-cap physicians also reduced revascularization rates after ischemic evaluation (-23%; 95% CI, -40% to -4%; P = .02; driven by fewer percutaneous coronary interventions). Changes in overall ischemic evaluation rates were similar for new-cap and control physicians (-0.05%; 95% CI, -8.0% to 7.9%; P = .98). Conclusions and Relevance Physicians substantially altered their approach to coronary artery disease testing and follow-up after initial ischemic evaluations following adoption of damage caps. They performed a similar number of ischemic evaluations but conducted fewer initial left heart catheterizations, referred fewer stress-tested patients for left heart catheterizations, and referred fewer patients for revascularization. These findings suggest that physicians tolerate greater clinical uncertainty in coronary artery disease testing and treatment if they face lower malpractice risk.

Exploring the Healthcare Value of Percutaneous Coronary Intervention: Appropriateness, Outcomes, and Costs in Michigan Hospitals. Circ Cardiovasc Qual Outcomes 2019; 11:e004328. [PMID: 29853465 DOI: 10.1161/circoutcomes.117.004328] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/05/2017] [Accepted: 04/26/2018] [Indexed: 11/16/2022]
Abstract
BACKGROUND Assessments of healthcare value have largely focused on measuring outcomes of care at a given level of cost with less attention paid to appropriateness. However, understanding how appropriateness relates to outcomes and costs is essential to determining healthcare value. METHODS AND RESULTS In a retrospective cohort study design, administrative data from fee-for-service Medicare patients undergoing percutaneous coronary intervention (PCI) in Michigan hospitals between June 30, 2010, and December 31, 2014, were linked with clinical data from a statewide PCI registry to calculate hospital-level measures of (1) appropriate use criteria scores, (2) 90-day risk-standardized readmission and mortality rates, and (3) 90-day risk-standardized episode costs. We then used Spearman correlation coefficients to assess the relationship between these measures. A total of 29 839 PCIs were performed at 33 PCI hospitals during the study period. A total of 13.3% were for ST-segment-elevation myocardial infarction, 25.0% for non-ST-segment-elevation myocardial infarction, 47.1% for unstable angina, 9.8% for stable angina, and 4.7% for other. The overall hospital-level mean appropriate use criteria score was 8.4±0.2. Ninety-day risk-standardized readmission occurred in 23.7%±3.7% of cases, 90-day risk-standardized mortality in 4.3%±0.6%, and mean risk-standardized episode costs were $26 159±$1074. Hospital-level appropriate use criteria scores did not correlate with 90-day readmission, mortality, or episode costs. CONCLUSIONS Among Medicare patients undergoing PCI in Michigan, we found hospital-level appropriate use criteria scores did not correlate with 90-day readmission, mortality, or episode costs. This finding suggests that a comprehensive understanding of healthcare value requires multidimensional consideration of appropriateness, outcomes, and costs.

Abstract
PURPOSE OF REVIEW Non-ST-elevation myocardial infarction (NSTEMI) is an urgent medical condition that requires prompt application of simultaneous pharmacologic and non-pharmacologic therapies. The variation in patient clinical characteristics coupled with the multitude of treatment modalities makes optimal and timely management challenging. This review summarizes risk stratification of patients, the role and timing of revascularization, and highlights important considerations in the revascularization approach with attention to individual patient characteristics. RECENT FINDINGS The early invasive management of NSTEMI has fostered a reduction in future ischemic events. Risk calculators are helpful in determining which patients should receive early invasive management. As many patients have multivessel disease, identifying the true culprit lesion can be challenging. Special attention should be given to those at the highest risk, such as diabetics, patients with renal failure, and those with left main disease. In patients with acute coronary syndrome, the decision and mode of revascularization should carefully integrate the patient's clinical characteristics as well as the complexity of the coronary anatomy.

Abstract
AIMS Assessment of the coronary circulation has been based largely on pressure ratios (epicardial) and resistance (micro-vessels). Simultaneous assessment of epicardial (CEPI) and microvascular conductance (CMICRO) provides an intuitive approach using the same units for both coronary domains and expressing the actual deliverability of blood. The aim of this study was to develop a novel integral method for assessing the functional severity of epicardial and microvascular disease. METHODS AND RESULTS We performed intracoronary pressure and Doppler flow velocity measurements in 403 vessels in 261 patients with stable coronary artery disease. Hyperaemic mid-to-late diastolic pressure and flow velocity (PV) relationships were calculated. The slope of the aortic PV indicates the overall conductance and the slope of the distal PV relationship represents CMICRO. The intercept with the x-axis represents zero-flow pressure (Pzf). CEPI was derived from microvascular and overall conductance. Median CEPI was higher compared to CMICRO (4.2 [2.1-8.0] versus 1.3 [1.0-1.7] cm/s/mmHg, p<0.001). CMICRO was independent of stenosis severity (1.3 [1.0-1.7] in FFR ≤0.80 versus 1.4 [1.0-1.8] in FFR >0.8, p=0.797). ROC curves (using FFR and HSR concordant vessels as standard) demonstrated an excellent ability of CEPI to characterise significant stenoses (AUC 0.93). When CEPI<CMICRO, a decrease in flow velocity and coronary pressure (optimal cut-off value 0.97, AUC 0.90) was demonstrated. CONCLUSIONS A comprehensive assessment of separate CEPI and CMICRO was feasible. CEPI has a remarkable diagnostic efficiency to detect a clinically relevant stenosis. When CEPI<CMICRO, distal flow and pressure decrease steeply, indicating myocardial ischaemia. CMICRO can be used to explore the severity of microvascular disease.

Abstract
Background Certificate of need ( CON ) regulations are intended to coordinate new healthcare services, limit expansion of unnecessary new infrastructure, and limit healthcare costs. However, there is limited information about the association of CON regulations with the appropriateness and outcomes of percutaneous coronary interventions ( PCI ). The study sought to characterize the association between state CON regulations and PCI appropriateness. Methods and Results We used data from the American College of Cardiology's Cath PCI Registry to analyze 1 268 554 PCI s performed at 1297 hospitals between January 2010 and December 2011. We used the Appropriate Use Criteria to classify PCI procedures as appropriate, maybe appropriate, or rarely appropriate and used Chi-square analyses to assess whether the proportions of PCI s in each Appropriate Use Criteria category varied depending on whether the procedure had been performed in a state with or without CON regulations. Analyses were repeated stratified by whether or not the procedure had been performed in the setting of an acute coronary syndrome ( ACS ). Among 1 268 554 PCI procedures, 674 384 (53.2%) were performed within 26 CON states. The proportion of PCI s classified as rarely appropriate in CON states was slightly lower compared with non- CON states (3.7% versus 4.0%, P<0.01). Absolute differences were larger among non- ACS PCI (23.1% versus 25.0% [ P<0.01]) and were not statistically significantly different in ACS (0.62% versus 0.63% [ P>0.05]). Conclusions States with CON had lower proportions of rarely appropriate PCI s, but the absolute differences were small. These findings suggest that CON regulations alone may not limit rarely appropriate PCI among patients with and without ACS .

Abstract
OBJECTIVE Guidelines recommend non-invasive ischaemia testing (NIIT) for the majority of patients with suspected ischaemic heart disease in a non-emergency setting. A substantial number of these patients undergo diagnostic coronary angiography (CA) without therapeutic intervention inappropriately due to lacking preceding NIIT. The aim of this study was to evaluate the effect of voluntary healthcare models with limited access on the proportion of patients without NIIT prior to elective purely diagnostic CA. DESIGN Retrospective cross-sectional analysis of insurance claims data from 2012 to 2015. Data included claims of basic and voluntary healthcare models from approximately 1.2 million patients enrolled with the Helsana Insurance Group. Voluntary healthcare models with limited health access are divided into gate keeping (GK) and managed care (MC) capitation models. INCLUSION CRITERIA patients undergoing CA. EXCLUSION CRITERIA Patients<18 years, incomplete health insurance data coverage, acute cardiac ischaemia and emergency procedures, therapeutic CA (coronary angioplasty/stenting or coronary artery bypass grafting). The effect of voluntary healthcare models on the proportion of NIIT undertaken within 2 months before diagnostic CA was assessed by means of multiple logistic regression analysis, controlled for influencing factors. RESULTS 9173 patients matched inclusion criteria. 33.2% (3044) did not receive NIIT before CA. Compared with basic healthcare models, MC was independently associated with a higher proportion of NIIT (p<0.001, OR 1.17, CI 1.045 to 1.312), when additionally controlled for demographics, insurance coverage, inpatient treatment, cardiovascular medication, chronic comorbidities, high-risk status (patients with therapeutic cardiac intervention 1 month after or 18 months prior to diagnostic CA). GK models showed no significant association with the rate of NIIT (p=0.07, OR 1.11, CI 0.991 to 1.253). CONCLUSIONS In a non-GK healthcare system, voluntary MC healthcare models with capitation were associated with a reduced inappropriate use of diagnostic CA compared with GK or basic models.

Abstract
Background The use of inappropriate elective Percutaneous Coronary Intervention (PCI) has decreased over time, but hospital-level variation in the use of inappropriate PCI persists. Understanding the barriers and facilitators to the implementation of Appropriate Use Criteria (AUC) guidelines may inform efforts to improve elective PCI appropriateness. Methods All hospitals performing PCI in Washington State were categorized by their use of inappropriate elective PCI in 2010 to 2013. Semi-structured, qualitative telephone interviews were then conducted with 17 individual interviews at 13 sites in Washington State to identify barriers and facilitators to the implementation of the AUC guidelines. An inductive and deductive, team-based analytical approach, drawing primarily on Matrix analysis was performed to identify factors affecting implementation of the AUC. Results Specific facilitators were identified that supported successful implementation of the AUC. These included collaborative catheterization laboratory environments that allow all staff to participate with questions and opinions; ongoing AUC education with catheterization laboratory teams and referring providers; internal AUC peer review processes; interventional cardiologist be directly involved with the pre-procedural review process; checklist-based algorithms for pre-procedural documentation; systems redesign to include insurance companies; and AUC educational information with patients. Barriers to implementation of the AUC included external pressures, such as competition for patients, and the lack of shared medical records with sites that referred patients for coronary angiography. Conclusions The identified facilitators enabled sites to successfully implement the AUC. Catheterization laboratories struggling to successfully implement the AUC may consider utilizing these strategies to improve their processes to improve patient selection for elective PCI.

Abstract
Aims To elucidate the effects of intensive LDL-C lowering treatment with a standard dose of statin and ezetimibe in patients with dyslipidaemia and high risk of coronary events, targeting LDL-C less than 70 mg/dL (1.8 mmol/L), compared with standard LDL-C lowering lipid monotherapy targeting less than 100 mg/dL (2.6 mmol/L). Methods and results The HIJ-PROPER study is a prospective, randomized, open-label trial to assess whether intensive LDL-C lowering with standard-dose pitavastatin plus ezetimibe reduces cardiovascular events more than standard LDL-C lowering with pitavastatin monotherapy in patients with acute coronary syndrome (ACS) and dyslipidaemia. Patients were randomized to intensive lowering (target LDL-C < 70 mg/dL [1.8 mmol/L]; pitavastatin plus ezetimibe) or standard lowering (target LDL-C 90 mg/dL to 100 mg/dL [2.3–2.6 mmol/L]; pitavastatin monotherapy). The primary endpoint was a composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, unstable angina, and ischaemia-driven revascularization. Between January 2010 and April 2013, 1734 patients were enroled at 19 hospitals in Japan. Patients were followed for at least 36 months. Median follow-up was 3.86 years. Mean follow-up LDL-C was 65.1 mg/dL (1.68 mmol/L) for pitavastatin plus ezetimibe and 84.6 mg/dL (2.19 mmol/L) for pitavastatin monotherapy. LDL-C lowering with statin plus ezetimibe did not reduce primary endpoint occurrence in comparison with standard statin monotherapy (283/864, 32.8% vs. 316/857, 36.9%; HR 0.89, 95% CI 0.76–1.04, P = 0.152). In, ACS patients with higher cholesterol absorption, represented by elevated pre-treatment sitosterol, was associated with significantly lower incidence of the primary endpoint in the statin plus ezetimibe group (HR 0.71, 95% CI 0.56–0.91). Conclusion Although intensive lowering with standard pitavastatin plus ezetimibe showed no more cardiovascular benefit than standard pitavastatin monotherapy in ACS patients with dyslipidaemia, statin plus ezetimibe may be more effective than statin monotherapy in patients with higher cholesterol absorption; further confirmation is needed. Trial No UMIN000002742, registered as an International Standard Randomized Controlled Trial.

Abstract
The major goals of treating ischemic heart disease are to reduce angina, improve quality of life, and ultimately reduce mortality. While medical therapy can effectively address these aims, there is still much research and debate about the role of percutaneous coronary intervention in the treatment spectrum-specifically, whether or not stenting prolongs life or simply treats symptoms without impacting survival. The data supporting revascularization for survival benefit came from patients who underwent bypass graft surgery prior to the introduction of effective medical management. Although both physicians and patients continue to believe in the life-saving ability of coronary stenting, little data exist to support this belief outside of when used during an acute myocardial infarction. Strategy trials designed to test the benefit of coronary stenting have limitations that have curbed physicians' willingness to accept the results, but they provide the best evidence for how to optimally manage these patients. In this article, we explore the data supporting the use of coronary stenting for various indications and the questions that remain to be answered.

Abstract
BACKGROUND Overtreatment is a cause of preventable harm and waste in health care. Little is known about clinician perspectives on the problem. In this study, physicians were surveyed on the prevalence, causes, and implications of overtreatment. METHODS 2,106 physicians from an online community composed of doctors from the American Medical Association (AMA) masterfile participated in a survey. The survey inquired about the extent of overutilization, as well as causes, solutions, and implications for health care. Main outcome measures included: percentage of unnecessary medical care, most commonly cited reasons of overtreatment, potential solutions, and responses regarding association of profit and overtreatment. FINDINGS The response rate was 70.1%. Physicians reported that an interpolated median of 20.6% of overall medical care was unnecessary, including 22.0% of prescription medications, 24.9% of tests, and 11.1% of procedures. The most common cited reasons for overtreatment were fear of malpractice (84.7%), patient pressure/request (59.0%), and difficulty accessing medical records (38.2%). Potential solutions identified were training residents on appropriateness criteria (55.2%), easy access to outside health records (52.0%), and more practice guidelines (51.5%). Most respondents (70.8%) believed that physicians are more likely to perform unnecessary procedures when they profit from them. Most respondents believed that de-emphasizing fee-for-service physician compensation would reduce health care utilization and costs. CONCLUSION From the physician perspective, overtreatment is common. Efforts to address the problem should consider the causes and solutions offered by physicians.

Lancet 2017; 390:156-168.

Abstract
Overuse, which is defined as the provision of medical services that are more likely to cause harm than good, is a pervasive problem. Direct measurement of overuse through documentation of delivery of inappropriate services is challenging given the difficulty of defining appropriate care for patients with individual preferences and needs; overuse can also be measured indirectly through examination of unwarranted geographical variations in prevalence of procedures and care intensity. Despite the challenges, the high prevalence of overuse is well documented in high-income countries across a wide range of services and is increasingly recognised in low-income countries. Overuse of unneeded services can harm patients physically and psychologically, and can harm health systems by wasting resources and deflecting investments in both public health and social spending, which is known to contribute to health. Although harms from overuse have not been well quantified and trends have not been well described, overuse is likely to be increasing worldwide.

Outcomes of PCI in Relation to Procedural Characteristics and Operator Volumes in the United States. J Am Coll Cardiol 2017; 69:2913-2924. [PMID: 28619191 PMCID: PMC5784411 DOI: 10.1016/j.jacc.2017.04.032] [Citation(s) in RCA: 95] [Impact Index Per Article: 13.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2017] [Revised: 04/06/2017] [Accepted: 04/07/2017] [Indexed: 11/27/2022]
Abstract
BACKGROUND Professional guidelines have reduced the recommended minimum number to an average of 50 percutaneous coronary intervention (PCI) procedures performed annually by each operator. Operator volume patterns and associated outcomes since this change are unknown. OBJECTIVES The authors describe herein PCI operator procedure volumes; characteristics of low-, intermediate-, and high-volume operators; and the relationship between operator volume and clinical outcomes in a large, contemporary, nationwide sample. METHODS Using data from the National Cardiovascular Data Registry collected between July 1, 2009, and March 31, 2015, we examined operator annual PCI volume. We divided operators into low- (<50 PCIs per year), intermediate- (50 to 100 PCIs per year), and high- (>100 PCIs per year) volume groups, and determined the adjusted association between annual PCI volume and in-hospital outcomes, including mortality. RESULTS The median annual number of procedures performed per operator was 59; 44% of operators performed <50 PCI procedures per year. Low-volume operators more frequently performed emergency and primary PCI procedures and practiced at hospitals with lower annual PCI volumes. Unadjusted in-hospital mortality was 1.86% for low-volume operators, 1.73% for intermediate-volume operators, and 1.48% for high-volume operators. The adjusted risk of in-hospital mortality was higher for PCI procedures performed by low- and intermediate-volume operators compared with those performed by high-volume operators (adjusted odds ratio: 1.16 for low versus high; adjusted odds ratio: 1.05 for intermediate vs. high volume) as was the risk for new dialysis post PCI. No volume relationship was observed for post-PCI bleeding. CONCLUSIONS Many PCI operators in the United States are performing fewer than the recommended number of PCI procedures annually. Although absolute risk differences are small and may be partially explained by unmeasured differences in case mix between operators, there remains an inverse relationship between PCI operator volume and in-hospital mortality that persisted in risk-adjusted analyses.

[PMID: 28599642 PMCID: PMC5466717 DOI: 10.1186/s12872-017-0592-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2017] [Accepted: 06/05/2017] [Indexed: 11/26/2022] Open
Abstract
Background The volume and percentage of percutaneous coronary interventions (PCIs) performed for nonacute indications have declined in the United States since 2007. However, little is known if similar trends occurred in Taiwan. Methods We used data from Taiwan National Health Insurance inpatient claims to examine the regional and hospital variations in the extent of decline in the percentage of nonacute indication PCIs from 2007 to 2012. Results The volume of total PCIs persistently increased from 29,032 in 2007 to 35,811 in 2010 and 37,426 in 2012. However, the volume of nonacute indication PCIs first increased from 7916 in 2007 to 9143 in 2009 and then decreased to 8666 in 2012. The percentage of nonacute indication PCIs steadily decreased from 27% in 2007 to 26% in 2009 and then to 23% in 2012, a − 15% change. The extent of decline was largest in the North region (from 27% to 21%, a − 22% change) and least in Kaopin region (from 20% to 18%, a − 13% change). Of the 71 hospitals studied, 14 did not show a decreasing trend. Five of the 14 hospitals even showed an increasing trend, with a percentage change >10% between 2007 and 2012. In 2012, 6 hospitals had a nonacute indication PCI percentage >35%. Conclusions In Taiwan, four-fifths of the hospitals showed a decline in the percentage of nonacute indication PCIs from 2007 to 2012. It is plausible that Taiwanese cardiologists would have been influenced by the recommendations of crucial US trials and guidelines.

Abstract
Background and Objectives Appropriate use criteria (AUC) was developed to improve the quality of percutaneous coronary intervention (PCI). However, these criteria should consider the current practice pattern in the country where they are being applied. Materials and Methods The algorithm for the Korean PCI practice pattern (KP3) was developed by modifying the United States-derived AUC in expert consensus meetings. KP3 class A was defined as any strategy with evidence from randomized trials that was more conservative for PCI than medical therapy or coronary artery bypass graft (CABG). Class C was defined as any strategy with less evidence from randomized trials and more aggressive for PCI than medical therapy or CABG. Class B was defined as a strategy that was partly class A and partly class C. We applied the KP3 classification system to the Korean PCI registry. Results The KP3 class A was noted in 67.7% of patients, class B in 28.8%, and class C in 3.5%. The median proportion of class C cases per center was 2.0%. The distribution of KP3 classes varied significantly depending on clinical and angiographic characteristics. The proportion of KP3 class C cases per center was not significantly dependent on PCI volume, but rather on the percentage of ACS cases in each center. Conclusion We report the current PCI practice pattern by applying the new KP3 classification in a nationwide PCI registry. The results should be interpreted carefully with due regard for the complex relationships between the determining variables and the healthcare system in Korea.

Abstract
Overdiagnosis and overtreatment are often thought of as relatively recent phenomena in modern medicine, influenced by a contemporary combination of technology, specialization, payment models, marketing, and supply-related demand. Several investigators have reported discrepancies between the angiographic and functional severity of coronary angiographic stenosis. However, the visual anatomic assessment of the coronary lesion severity continues in daily practice. We evaluated the consecutive all coronary angiograms performed between January 2015 and December 2015 and examined only patients who had previous coronary artery bypass grafting (CABG) to analyze the cases with regard to presence of the competitive flow (CF) between the native left anterior descending coronary artery (LAD) and left internal mammary artery (LIMA) graft. A total of 8,248 diagnostic coronary angiographies were performed between January 2015 and December 2015 at our facility. Of these, 886 coronary angiographies of CABG patients were detected. Whereas LIMA graft occlusion detected in 19 patient (2.1%), the LIMA-LAD CF rate was found in 86 (9.7%) CABG patients. The angiographic severity of the LAD stenosis in CF group evaluated as mild in 20 (25%), moderate in 61 (70%), and severe coronary artery disease in 4 (5%) patients. Our results showed that there is 9.7% rate of LIMA-LAD CF. Therefore, some unnecessary coronary stenting or CABG procedures might have been performed due to limited use of functional testing for clinical decision making. The functional angiography should play a more prominent role in catheterization laboratories as recommended by current revascularization guidelines to prevent overdiagnosis, misdiagnosis, or incorrect treatment decisions.

Abstract
Coronary artery disease (CAD) is a leading cause of death and disability worldwide. Cardiovascular magnetic resonance (CMR) is established in clinical practice guidelines with a growing evidence base supporting its use to aid the diagnosis and management of patients with suspected or established CAD. CMR is a multi-parametric imaging modality that yields high spatial resolution images that can be acquired in any plane for the assessment of global and regional cardiac function, myocardial perfusion and viability, tissue characterisation and coronary artery anatomy, all within a single study protocol and without exposure to ionising radiation. Advances in technology and acquisition techniques continue to progress the utility of CMR across a wide spectrum of cardiovascular disease, and the publication of large scale clinical trials continues to strengthen the role of CMR in daily cardiology practice. This article aims to review current practice and explore the future directions of multi-parametric CMR imaging in the investigation of stable CAD.
