Case Volumes and Outcomes Among Early-Career Interventional Cardiologists in the United States.

BACKGROUND: Little is known about the procedural characteristics, case volumes, and mortality rates for early- vs non-early-career interventional cardiologists in the United States. OBJECTIVES: This study examined operator-level data for patients who underwent percutaneous coronary intervention (PCI) between April 2018 and June 2022. METHODS: Data were collected from the National Cardiovascular Data Registry CathPCI Registry, American Board of Internal Medicine certification database, and National Plan and Provider Enumeration System database. Early-career operators were within 5 years of the end of training. Annual case volume, expected mortality and bleeding risk, and observed/predicted mortality and bleeding outcomes were evaluated. RESULTS: A total of 1,451 operators were early career; 1,011 changed their career status during the study; and 6,251 were non-early career. Overall, 514,540 patients were treated by early-career and 2,296,576 patients by non-early-career operators. The median annual case volume per operator was 59 (Q1-Q3: 31-97) for early-career and 57 (Q1-Q3: 28-100) for non-early-career operators. Early-career operators were more likely to treat patients presenting with ST-segment elevation myocardial infarction and urgent indications for PCI (both P < 0.001). The median predicted mortality risk was 2.0% (Q1-Q3: 1.5%-2.7%) for early-career and 1.8% (Q1-Q3: 1.2%-2.4%) for non-early-career operators. The median predicted bleeding risk was 4.9% (Q1-Q3: 4.2%-5.7%) for early-career and 4.4% (Q1-Q3: 3.7%-5.3%) for non-early-career operators. After adjustment, an increased risk of mortality (OR: 1.08; 95% CI: 1.05-1.17; P < 0.0001) and bleeding (OR: 1.08; 95% CI: 1.05-1.12; P < 0.0001) were associated with early-career status. CONCLUSIONS: Early-career operators are caring for patients with more acute presentations and higher predicted risk of mortality and bleeding compared with more experienced colleagues, with modestly worse outcomes. These data should inform institutional practices to support the development of early-career proceduralists.

Factors Impacting Physician Prognostic Accuracy in Heart Failure Patients With Reduced Left Ventricular Ejection Fraction.

BACKGROUND: A recent study showed that the accuracy of heart failure (HF) cardiologists and family doctors to predict mortality in outpatients with HF proved suboptimal, performing less well than models. OBJECTIVES: The authors sought to evaluate patient and physician factors associated with physician accuracy. METHODS: The authors included outpatients with HF from 11 HF clinics. Family doctors and HF cardiologists estimated patient 1-year mortality. They calculated predicted mortality using the Seattle HF Model and followed patients for 1 year to record mortality (or urgent heart transplant or ventricular assist device implant as mortality-equivalent events). Using multivariable logistic regression, the authors evaluated associations among physician experience and confidence in estimates, duration of patient-physician relationship, patient-physician sex concordance, patient race, and predicted risk, with concordant results between physician and model predictions. RESULTS: Among 1,643 patients, 1-year event rate was 10% (95% CI: 8%-12%). One-half of the estimates showed discrepant results between model and physician predictions, mainly owing to physician risk overestimation. Discrepancies were more frequent with increasing patient risk from 38% in low-risk to ∼75% in high-risk patients. When making predictions on male patients, female HF cardiologists were 26% more likely to have discrepant predictions (OR: 0.74; 95% CI: 0.58-0.94). HF cardiologist estimates in Black patients were 33% more likely to be discrepant (OR: 0.67; 95% CI: 0.45-0.99). Low confidence in predictions was associated with discrepancy. Analyses restricted to high-confidence estimates showed inferior calibration to the model, with risk overestimation across risk groups. CONCLUSIONS: Discrepant physician and model predictions were more frequent in cases with perceived increased risk. Model predictions outperform physicians even when they are confident in their predictions. (Predicted Prognosis in Heart Failure [INTUITION]; NCT04009798).

Prescription, Compliance, and Burden Associated with Salt-Restricted Diets in Heart Failure Patients: Results from the French National OFICSel Observatory.

(1) Background: There is much debate about the use of salt-restricted diet for managing heart failure (HF). Dietary guidelines are inconsistent and lack evidence. (2) Method: The OFICSel observatory collected data about adults hospitalised for HF. The data, collected using study-specific surveys, were used to describe HF management, including diets, from the cardiologists' and patients' perspectives. Cardiologists provided the patients' clinical, biological, echocardiography, and treatment data, while the patients provided dietary, medical history, sociodemographic, morphometric, quality of life, and burden data (burden scale in restricted diets (BIRD) questionnaire). The differences between the diet recommended by the cardiologist, understood by the patient, and the estimated salt intake (by the patient) and diet burden were assessed. (3) Results: Between March and June 2017, 300 cardiologists enrolled 2822 patients. Most patients (90%) were recommended diets with <6 g of salt/day. Mean daily salt consumption was 4.7 g (standard deviation (SD): 2.4). Only 33% of patients complied with their recommended diet, 34% over-complied, and 19% under-complied (14% unknown). Dietary restrictions in HF patients were associated with increased burden (mean BIRD score of 8.1/48 [SD: 8.8]). (4) Conclusion: Healthcare professionals do not always follow dietary recommendations, and their patients do not always understand and comply with diets recommended. Restrictive diets in HF patients are associated with increased burden. An evidence-based approach to developing and recommending HF-specific diets is required.

Awareness, diagnosis and treatment of heterozygous familial hypercholesterolemia (HeFH) - Results of a US national survey.

BACKGROUND: HeFH is a common inherited disorder that leads to markedly elevated LDL-cholesterol from birth and premature cardiovascular disease. HeFH is frequently underdiagnosed and undertreated. OBJECTIVE: To compare how well primary care physicians and cardiologists recognize and treat HeFH. METHODS: The National Lipid Association surveyed 500 primary care physicians and 500 cardiologists in the US who have patients with baseline LDL-cholesterol ≥ 190 mg/dL. The survey was conducted between August 29 and September 30, 2019. RESULTS: For a hypothetical case of HeFH, 57% of cardiologists versus 43% of primary care physicians made the correct diagnosis (P<0.001). Among respondents, 21% of cardiologists versus 29% of primary care physicians have never made a diagnosis of HeFH in a patient with an LDL-cholesterol ≥ 190 mg/dL (P<0.004). Only 7% of cardiologists versus 5% of primary care physicians would refer to a lipid specialist (P=0.05). For additional LDL-cholesterol lowering after statins, 58% of cardiologists versus 48% of primary care physicians would prescribe a PCSK9 inhibitor (P=0.004); however, 30% of cardiologists versus 53% of primary care physicians have never prescribed a PSCK9 inhibitor in an HeFH patient (P<0.001). CONCLUSION: Although cardiologists compared to primary care physicians are somewhat more likely to recognize and treat HeFH patients according to guidelines, both physician specialties do not adequately recognize or treat HeFH. There is a need for more education and training in recognizing and treating HeFH, greater access to lipid specialists, and fewer barriers for PCSK9 inhibitor use.

Clinician needs and perceptions about cardioneuroablation for recurrent vasovagal syncope: An international clinician survey.

BACKGROUND: Cardioneuroablation (CNA) targets the intrinsic cardiac autonomic nervous system ganglionated plexi located in the peri-atrial epicardial fat. There is increasing interest in CNA as a treatment of vasovagal syncope (VVS), despite no randomized clinical trial (RCT) data. OBJECTIVE: The purpose of this study was to poll the opinion on CNA) for VVS. METHODS: A REDCap (Research Electronic Data Capture) survey was administered to international physicians treating patients with VVS on their opinion about patient selection criteria, ablation approach, RCT design, and most appropriate end points for CNA procedures. RESULTS: The survey was completed by 118 physicians; 86% were cardiac electrophysiologists. The majority of respondents (79%) would consider referring a patient with refractory VVS for CNA, and 27% have performed CNA for VVS themselves. Most felt patient selection should require a head-up tilt test with a cardioinhibitory response (67%) and suggest a minimum age of 18 years with a median of 3 (interquartile range 2-5) episodes in the past year. There were differences in patient selection between physicians who have performed CNA themselves and those who have not. The majority felt that the ablation strategy should include both atria (70%) with an anatomical approach in combination with autonomic stimulation (85%). Performing a sham procedure in the control arm was supported by 56% of respondents, providing equipoise in RCT design. The preferred primary outcome was freedom from syncope within 1 year of follow-up. CONCLUSION: There is widespread support for well-designed RCTs to confirm the hypothesized clinical benefit of CNA, provide data to guide the risk-benefit equations during patient selection, and appropriately estimate the placebo effect.

Work-life balance: a comparison of women in cardiology and other specialties.

OBJECTIVE: Significant gender disparities exist in some medical specialties, particularly cardiology. We assessed work, personal life and work-life balance in women in cardiology in Australia and New Zealand (NZ), compared with other specialties, to determine factors that may contribute to the lack of women in the specialty. METHODS: This study is a prospective survey-based cohort study comparing cardiology and non-cardiology specialties. An online survey was completed by female doctors in Australia and NZ, recruited via email lists and relevant social media groups. The survey included demographics, specialty, stage of training, work hours/setting, children and relationships, career satisfaction, income and perceptions of specialty. RESULTS: 452 participants completed the survey (median age 36 years), of which 57 (13%) worked in cardiology. Of all respondents, 84% were partnered and 75% had children, with no difference between cardiology and non-cardiology specialties. Compared with non-cardiology specialties, women in cardiology worked more hours per week (median 50 hours vs 40 hours, p<0.001), were more likely to be on call more than once per week (33% vs 12%, p<0.001) and were more likely to earn an annual income >$3 00 000 (35% vs 10%, p<0.001). Women in cardiology were less likely to agree that they led a balanced life (33% vs 51%, p=0.03) or that their specialty was female friendly (19% vs 75%, p<0.001) or family friendly (20% vs 63%, p<0.001). CONCLUSIONS: Compared with other specialties, women in cardiology reported poorer work-life balance, greater hours worked and on-call commitments and were less likely to perceive their specialty as female friendly or family friendly. Addressing work-life balance may attract and retain more women in cardiology.

[Assessment of the practices and knowledge among cardiologists regarding radiation protection in Tunisia]. / Évaluation des pratiques et connaissances en radioprotection des cardiologues en Tunisie.

INTRODUCTION: interventional cardiology procedures have become complex and expensive in time with a higher risk of exposure to ionizing radiations. The purpose of our study was to assess radiation protection knowledge and practices among Tunisian cardiologists exposed to X-rays. METHODS: we conducted a descriptive, analytical study in October 2019. An anonymous survey on the knowledge and practices regarding radiation protection was sent to all Tunisian cardiologists exposed to X-rays. RESULTS: among 126 cardiologists exposed to X-rays and having received the survey, 58 physicians responded to the survey (48%), with a male predominance (72%, n=42). Thirty-eight physicians (65%) were public sector workers. Average years of working experience were 12.02 years (SD 6.88 years). Half of doctors had a knowledge score of less than 50%. The average practice score was 43.83 (SD 13.95%). Wearing a lead apron, thyroid shield, dosimeter, lead glasses, lead cap accounted for 100% (n=58), 86.2% (n=50), 30.7% (n=18), 12.1% (n=7) and 1.7% (n=1) respectively. There was no correlation between scores and doctor's age as well as the length of working experience. There was no statistical differences between knowledge scores of males and females (p=0.06) or between public sector and private sector (p=0.9). Practice score was significantly higher among men (0.007) and interventional cardiologists compared to rhythmologists and pediatric cardiologists (p<0.001). CONCLUSION: the level of knowledge and practices among Tunisian cardiologists regarding radiation protection is generally insufficient. Then, health authorities should implement regular training programs.

Racial Diversity Among American Cardiologists: Implications for the Past, Present, and Future.

In the United States, race-based disparities in cardiovascular disease care have proven to be pervasive, deadly, and expensive. African American/Black, Hispanic/Latinx, and Native/Indigenous American individuals are at an increased risk of cardiovascular disease and are less likely to receive high-quality, evidence-based medical care as compared with their White American counterparts. Although the United States population is diverse, the cardiovascular workforce that provides its much-needed care lacks diversity. The available data show that care provided by physicians from racially diverse backgrounds is associated with better quality, both for minoritized patients and for majority patients. Not only is cardiovascular workforce diversity associated with improvements in health care quality, but racial diversity among academic teams and research scientists is linked with research quality. We outline documented barriers to achieving workforce diversity and suggest evidence-based strategies to overcome these barriers. Key strategies to enhance racial diversity in cardiology include improving recruitment and retention of racially diverse members of the cardiology workforce and focusing on cardiovascular health equity for patients. This review draws attention to academic institutions, but the implications should be considered relevant for nonacademic and community settings as well.

Regional Distribution of Cardiologists and Prescription Patterns of Sodium-Glucose Transporter-2 Inhibitors in Japan.

The clinical evidence is accumulating since 2015 that anti-diabetic sodium-glucose cotransporter 2 (SGLT2) inhibitors have the beneficial effect of cardiovascular and, recently, renal protection. Although it is not well analyzed how the transfer of this new evidence into daily practice has expedited, we hypothesize that the recent usage of the drugs is positively associated with several certified cardiologists in each region.The 2016 annual and 2016-2017 increased number of SGLT2 inhibitor tablets, based on the National Database of Health Insurance Claims and Specific Health Checkups of Japan, were divided by the estimated number of patients with type 2 diabetes mellitus for each of the 47 prefectures. Then, regression analyses were performed to investigate the potential association of the number of certified cardiologists with the drug prescription.The 2016 prescription of ipragliflozin, dapagliflozin, luseogliflozin, canagliflozin, and empagliflozin was 2.7- to 4.4-fold different between prefectures. The 2016-2017 increased prescription volume also varied among prefectures by as large as 7.3-fold for ipragliflozin. Regression analysis revealed that the annual and increased prescription volume of all the SGLT2 inhibitors except luseogliflozin were higher in regions with more certified cardiologists (P < 0.05), even after adjusting for regional parameters.In conclusion, the regional number of certified cardiologists was positively associated with a 2016 annual of and 2016-2017 increase in SGLT2 inhibitor prescription amount, implying an early adopter role of clinical experts in healthcare delivery.

Treating heart failure in patients with diabetes: The view of the cardiologist.

Diabetes is a very important comorbidity in patients with heart failure. When both diseases coexist cardiovascular morbidity and mortality is greatly increased. Therefore, it is of clinical importance to treat both diseases as early as possible with an optimal therapy. Hitherto, heart failure therapy did not differ if a patient had concomitant diabetes. However, with SGLT-2 inhibitors having demonstrated to reduce hospitalization of heart failure independent of diabetes state and expected to be included into the ESC heart failure treatment guidelines in 2021 coexisting diabetes potentially will make a difference when to start therapy. In this article we provide an overview of current recommendations and also provide clinical considerations for the therapy of heart failure with concomitant diabetes.

Sexism experienced by consultant cardiologists in the United Kingdom.

OBJECTIVES: The aims were to compare the frequency with which male and female cardiologists experience sexism and to explore the types of sexism experienced in cardiology. METHODS: A validated questionnaire measuring experiences of sexism and sexual harassment was distributed online to 890 UK consultant cardiologists between March and May 2018. χ2 tests and pairwise comparisons with a Bonferroni correction for multiple analyses compared the experiences of male and female cardiologists. RESULTS: 174 cardiologists completed the survey (24% female; 76% male). The survey showed that 61.9% of female cardiologists have experienced discrimination of any kind, mostly related to gender and parenting, compared with 19.7% of male cardiologists. 35.7% of female cardiologists experienced unwanted sexual comments, attention or advances from a superior or colleague, compared with 6.1% of male cardiologists. Sexual harassment affected the professional confidence of female cardiologists more than it affected the confidence of male cardiologists (42.9% vs 3.0%), including confidence with colleagues (38% vs 10.6%) and patients (23.9% vs 4.6%). 33.3% of female cardiologists felt that sexism hampered opportunities for professional advancement, compared with 2.3% of male cardiologists. CONCLUSION: Female cardiologists in the UK experience more sexism and sexual harassment than male cardiologists. Sexism impacts the career progression and professional confidence of female cardiologists more, including their confidence when working with patients and colleagues. Future research is urgently needed to test interventions against sexism in cardiology and to protect the welfare of female cardiologists at work.

COVID-19 and Gender Disparities in Pediatric Cardiologists with Dependent Care Responsibilities.

The COVID-19 pandemic disproportionately affects females in the home and workplace. This study aimed to acquire information regarding the gender-specific effects of the COVID-19 lockdown on aspects of professional and personal lives of a subset of pediatric cardiologists. We sent an online multiple-choice survey to a listserv of Pediatric Cardiologists. Data collected included demographics, dependent care details, work hours, leave from work, salary cut, childcare hours before and after the COVID-19 peak lockdown/stay at home mandate and partner involvement. Two hundred forty-two pediatric cardiologists with dependent care responsibilities responded (response rate of 20.2%). A significantly higher proportion of females reported a salary cut (29.1% of females vs 17.6% of males, p = 0.04) and scaled back or discontinued work (14% vs 5.3%; p = 0.03). Prior to the COVID-19 lockdown phase, females provided more hours of dependent care. Females also reported a significantly greater increase in childcare hours overall per week (45 hours post/30 hours pre vs 30 hours post/20 hours pre for men; p < 0.001).  Male cardiologists were much more likely to have partners who reduced work hours (67% vs 28%; p < 0.001) and reported that their partners took a salary cut compared with partners of female cardiologists (51% vs 22%; p < 0.001). In conclusion, gender disparity in caregiver responsibilities existed among highly skilled pediatric cardiologists even before the COVID-19 pandemic. The pandemic has disproportionately affected female pediatric cardiologists with respect to dependent care responsibilities, time at work, and financial compensation.

Burnout and distress among physicians in a cardiovascular centre of a quaternary hospital network: a cross-sectional survey.

BACKGROUND: Burnout and distress have a negative impact on physicians and the treatment they provide. Our aim was to measure the prevalence of burnout and distress among physicians in a cardiovascular centre of a quaternary hospital network in Canada, and compare these outcomes to those for physicians at academic health science centres (AHSCs) in the United States. METHODS: We conducted a survey of physicians practising in a cardiovascular centre at 2 quaternary referral hospitals in Toronto, Ontario, between Nov. 27, 2018, and Jan. 31, 2019. The survey tool included the Well-Being Index (WBI), which measures fatigue, depression, burnout, anxiety or stress, mental and physical quality of life, work-life integration, meaning in work and distress; a score of 3 or higher indicated high distress. We also evaluated physicians' perception of the adequacy of staffing levels and of fair treatment in the workplace, and satisfaction with the electronic health record. We carried out standard univariate statistical comparisons using the χ2, Fisher exact or Kruskal-Wallis test as appropriate to perform univariate comparisons in the sample of respondents. We assessed the relation between a WBI score of 3 or higher and demographic characteristics. We compared univariate associations among WBI data for physicians at AHSCs in the US who completed the WBI to responses from our participants. RESULTS: The response rate to the survey was 84.1% (127/151). Of the 127 respondents, 83 (65.4%) reported burnout in the previous month, and 68 (53.5%) reported emotional problems. Sixty-nine respondents (54.3%) had a WBI score of 3 or higher. Respondents were more likely to have a WBI score of 3 or higher versus a score less than 3 if they perceived insufficient staffing levels (52/69 [75%] v. 26/58 [45%], p = 0.02) or unfair treatment (23/69 [33%] v. 8/58 [14%], p = 0.03), or were anesthesiologists (26/35 [74%] v. 43/92 [47%] for other specialists, p = 0.005). Compared to 21 594 physicians in practice at AHSCs in the US, our respondents had a higher mean WBI score (2.4 v. 1.8, p = 0.004) and reported a higher prevalence of burnout (65.4% v. 56.6%, p = 0.048). INTERPRETATION: Physicians in this study had high levels of burnout and distress, driven by the perception of inadequate staffing levels and being treated unfairly in the workplace. Addressing these institutional factors may improve physicians' work experience and patient outcomes.

Appropriate use of multimodality stress testing for chest pain in new patient referrals to cardiologists.

OBJECTIVE: In response to the growing use of imaging-based cardiac stress tests in the evaluation of stable ischemic heart disease, professional societies have developed appropriate use criteria (AUC). AUC will soon be linked to reimbursement of advanced diagnostic imaging for Medicare beneficiaries via Clinical Decision Support Mechanisms (CDSMs). We sought to characterize the frequency and type of stress test utilization for chest pain referrals evaluated by cardiologists and determine appropriateness. METHODS: We conducted a retrospective review of new patient referrals seen by general cardiologists at an academic medical center between 2016 and 2017 for a diagnosis of chest pain or angina. Type of stress test ordered, if any, and its appropriateness (Appropriate, May be appropriate, and Rarely appropriate) were ascertained based on the 2013 multimodality AUC guideline document. RESULTS: There were 535 total outpatients. After applying exclusion criteria, there were 349 patients in the sample; the average age was 52 ± 15 years and 53% were female. Most chest pain was nonanginal (65%). Pretest probability of CAD was most commonly intermediate (54%). A total of 183 patients (52%) were referred for stress testing. The majority of stress tests were considered appropriate (82%) by AUC. CONCLUSION: Most patients referred to cardiologists for evaluation of chest pain or angina had nonanginal chest pain and an intermediate pretest probability of CAD. Stress testing was ordered in about half of these patients and the majority were considered appropriate by AUC. These findings suggest that indiscriminate use of CDSMs may not be warranted.

[Prescribing habits of physical activity by cardiac physicians in Côte d'Ivoire]. / Habitudes de prescription de l'activité physique par des médecins cardiologues en Côte d'Ivoire.

Regular physical activity (PA) has multiple health benefits that contribute to the prevention and management of many non-communicable diseases such as cardiovascular disease. However, a large proportion of the world's population is not active enough to benefit its health. Despite the potential of physicians to increase the level of PA practice in both primary and secondary prevention, there appears to be little intervention in this direction during medical consultations. What is the situation in Côte d'Ivoire? We conducted a prospective study that focused on the description and analysis of the practice of PA awareness and prescribing of Côte d'Ivoire cardiologist physicians and to examine the extent to which their socio-cultural characteristicsdemographics, their personal PA practices, barriers and needs influenced their PA prescribing in primary or secondary prevention settings. The results showed a high rate of overweight and obesity (64 %) and a low level of PA (40 %). We noted a high rate of locating (90 %) and advising AP (92 %). High blood pressure (98 %) and obesity (94 %) were the major conditions for which physicians prescribed PA. They were mainly about walking (94 %) and through oral counselling (80 %). Among the brakes identified were mainly the lack of knowledge about PA prescribing, lack of consultation time and lack of motivation of patients in 48 %, 44 % and 34 % of cases respectively. In terms of the needs expressed to promote the prescription of PA, it was mainly the personal conviction of the physician of the interest of prescribing an PA (80 %), of the organization of training on the prescription of PA (78 %) and completion of patient handouts (56 %).

Characteristics of patients with adult congenital heart disease treated by non-specialized doctors: The potential loss of follow-up.

BACKGROUND: In the treatment of adult congenital heart disease (ACHD), the transfer of patients from pediatric cardiologists to ACHD cardiologists is of relevance. However, little is known about the clinical courses of ACHD patients that have been referred by non-CHD-specialized doctors (n-CSDs). METHODS: This retrospective cohort study included 230 patients (average age: 37 ± 15.2 years, male: 97) who were referred to a single specialized ACHD center between April 2016 and July 2019. We compared the characteristics and clinical courses between patients referred by n-CSDs and those referred by CHD-specialized-doctors (CSDs). RESULTS: Overall, 121 (53%) patients were referred by n-CSDs. Among them, 91 (75%) patients were referred by adult cardiologists. Univariate analysis showed that the patients referred by n-CSDs were older than those referred by CSDs (41.6 ± 16.3 vs. 32.0 ± 12.0 years, p < 0.01), were more likely to have simple CHD, and less likely to have severe CHD (27.0% vs. 12.8% and 16.5% vs. 40.4%, respectively, p < 0.01). Patients referred by n-CSDs were also more likely to have a history of loss of follow-up (16.5% vs. 3.7%, p < 0.01) and to require invasive treatments after referral, including cardiac surgeries and transcatheter interventions (47.9% vs. 26.6 %, p < 0.01). Notably, unintended invasive treatments that were not designated by the referring doctors were more frequently required in patients with moderate complexity referred by n-CSDs (50.0% vs. 23.3%, p = 0.02). CONCLUSIONS: Patients with moderate CHD complexity referred by n-CSDs are more likely to require unintended invasive treatments. Referrals to specialized ACHD centers may be most beneficial for these patients.
