RESUMEN

OBJECTIVES: To examine the association of operator sex with appropriateness and outcomes of percutaneous coronary intervention (PCI). BACKGROUND: Recent studies suggest that physician sex may impact outcomes for specific patient cohorts. There are no data evaluating the impact of operator sex on PCI outcomes. METHODS: We studied the impact of operator sex on PCI outcome and appropriateness among all patients undergoing PCI between January 2010 and December 2017 at 48 non-federal hospitals in Michigan. We used logistic regression models to adjust for baseline risk among patients treated by male versus female operators in the primary analysis. RESULTS: During this time, 18 female interventionalists and 385 male interventionalists had performed at least one PCI. Female interventionalists performed 6362 (2.7%) of 239,420 cases. There were no differences in the odds of mortality (1.48% vs. 1.56%, adjusted OR [aOR] 1.138, 95% CI: 0.891-1.452), acute kidney injury (3.42% vs. 3.28%, aOR 1.027, 95% CI: 0.819-1.288), transfusion (2.59% vs. 2.85%, aOR 1.168, 95% CI: 0.980-1.390) or major bleeding (0.95% vs. 1.07%, aOR 1.083, 95% CI: 0.825-1.420) between patients treated by female versus male interventionalist. While the absolute differences were small, PCIs performed by female interventional cardiologists were more frequently rated as appropriate (86.64% vs. 84.45%, p-value <0.0001). Female interventional cardiologists more frequently prescribed guideline-directed medical therapy. CONCLUSIONS: We found no significant differences in risk-adjusted in-hospital outcomes between PCIs performed by female versus male interventional cardiologists in Michigan. Female interventional cardiologists more frequently performed PCI rated as appropriate and had a higher likelihood of prescribing guideline-directed medical therapy.

RESUMEN

We sought to determine the risk of obstructive coronary artery disease (oCAD) associated with noncoronary atherosclerosis (cerebrovascular disease [CVD] or peripheral arterial disease [PAD]) and major adverse cardiac events following percutaneous coronary intervention (PCI). METHODS: Rates of the angiographic end point of oCAD were compared among patients with and without noncoronary atherosclerosis undergoing coronary angiography within the Veterans Health Administration between October 2007 and August 2015. The primary angiographic end point of oCAD was defined as left main stenosis ≥50% or any stenosis ≥70% in 1, 2, or 3 vessels. In patients who proceeded to PCI, the rate of the composite clinical end point of death, myocardial infarction, or stroke was compared among those with concomitant noncoronary atherosclerosis (CVD, PAD, or CVD + PAD) versus isolated CAD. RESULTS: Among 233,353 patients undergoing angiography, 9.6% had CVD, 12.4% had PAD, and 6.1% had CVD + PAD. Rates of oCAD were 57.9% for neither CVD nor PAD, 66.4% for CVD, 73.6% for PAD, and 80.9% for CVD + PAD. Compared with patients without noncoronary atherosclerosis, the adjusted risk of oCAD with CVD, PAD, or CVD + PAD was 1.03 (95% CI 1.02-1.04), 1.10 (95% CI 1.09-1.11), and 1.12 (95% CI 1.11-1.13), respectively. In patients who underwent PCI, the adjusted hazard for death, myocardial infarction, or stroke among those with CVD, PAD, or CVD + PAD was 1.36 (95% CI 1.26-1.45), 1.53 (95% CI 1.45-1.62), and 1.72 (95% CI 1.59-1.86), respectively. CONCLUSIONS: In patients undergoing coronary angiography, noncoronary atherosclerosis was associated with increased burden of oCAD and adverse events post-PCI.

RESUMEN

PURPOSE OF REVIEW: Increased awareness of cardiovascular disease in women has prompted studies to investigate gender-related disparities in acute coronary syndromes (ACSs). In this review, we discuss findings from current literature on the clinical presentation, pathophysiology, diagnosis, and management of ACS in women as compared to men. RECENT FINDINGS: Emerging data show that cardiovascular disease (CVD) continues to be the leading cause of death in women and the annual mortality rate from CVD remains higher in women compared to men. Recent studies demonstrate sex-specific differences in patients presenting with ACS. Comorbidities, especially diabetes, are more common in young women compared with age-matched men who develop acute myocardial infarction (AMI). Women are more likely to have atypical symptoms and nonobstructive coronary disease on angiography. Women are less likely to receive guideline-based therapies. They have higher rates of peri-procedural complications with PCI and are less likely to be referred to cardiac rehabilitation. Awareness of differences in the underlying pathophysiology of coronary disease in women compared to men may lead to improved gender-based diagnostic and treatment modalities. However, until more studies are performed, efforts should be directed toward improving delivery of current, gender-neutral guidelines in women just as in men.

RESUMEN

BACKGROUND: In type I diabetes (T1DM), alterations in LV function may occur due to changes in innervation, metabolism, and efficiency. OBJECTIVES: We evaluated the association between sympathetic nerve function, oxidative metabolism, resting blood flow, LV efficiency and function in healthy diabetics, and assessed gender differences. METHODS: Cross-sectional study of 45 subjects with T1DM, 60% females, age 34 ± 13 years, and 10 age-matched controls. Positron emission tomography (PET) imaging with [(11)C]acetate and [(11)C]meta-hydroxyephedrine was performed, in addition to cardiac magnetic resonance imaging. RESULTS: There were no significant differences in LV function, innervation, or oxidative metabolism between T1DM and controls. Cardiac oxidative metabolism was positively associated with higher levels of sympathetic activation, particularly in women. Diabetic women had significantly lower efficiency compared with diabetic men. Resting flow was significantly higher in diabetic women compared with diabetic men, and tended to be higher in female controls as well. CONCLUSIONS: Measures of myocardial function, metabolism, blood flow, and sympathetic activation were preserved in young, otherwise healthy, T1DM patients. However, T1DM women presented with greater myocardial oxidative metabolism requirements than men. Ongoing studies are evaluating changes over time.

RESUMEN

BACKGROUND: Despite the increase in the number of female physicians across most specialties within cardiology, <10% of clinical cardiac electrophysiology (EP) fellows are women. OBJECTIVES: This study sought to determine the factors that influence fellows-in-training (FITs) to pursue EP as a career choice and whether this differs by gender. METHODS: The authors conducted an online multiple-choice survey through the American College of Cardiology to assess the decision factors that influence FITs in the United States and Canada to pursue cardiovascular subspecialties. RESULTS: A total of 933 (30.5%) FITs completed the survey; 129 anticipated specializing in EP, 259 in interventional cardiology (IC), and 545 in a different field or were unsure. A total of 1 in 7 (14%) FITs indicated an interest in EP. Of this group, more men chose EP than women (84% vs 16%; P < 0.001). The most important factor that influenced FITs to pursue EP was a strong interest in the field. Women were more likely to be influenced by having a female role model (P = 0.001) compared with men. After excluding FITs interested in IC, women who deselected EP were more likely than men to be influenced by greater interest in another field (P = 0.004), radiation concerns (P = 0.001), lack of female role models (P = 0.001), a perceived "old boys' club" culture (P = 0.001) and discrimination/harassment concerns (P = 0.001). CONCLUSIONS: Women are more likely than men to be negatively influenced by many factors when it comes to pursuing EP as a career choice. Addressing those factors will help decrease the gender disparity in the field.

RESUMEN

Acquired cardiovascular conditions are a leading cause of maternal morbidity and mortality. A growing number of pregnant women have acquired and heritable cardiovascular conditions and cardiovascular risk factors. As the average age of childbearing women increases, the prevalence of acute coronary syndromes, cardiomyopathy, and other cardiovascular complications in pregnancy are also expected to increase. This document, the third of a 5-part series, aims to provide practical guidance on the management of such conditions encompassing pre-conception through acute management and considerations for delivery.

RESUMEN

BACKGROUND: Prior studies have shown a relationship between female gender and adverse outcomes after percutaneous coronary interventions (PCIs). Whether this relationship still exists with contemporary PCI remains to be determined. METHODS: We evaluated gender differences in clinical outcomes in a large registry of contemporary PCI. Data were prospectively collected from 22,725 consecutive PCIs in a multicenter regional consortium (Blue Cross Blue Shield of Michigan Cardiovascular Consortium) between January 2002 and December 2003. The primary end point was in-hospital all-cause mortality; other clinical outcomes evaluated included in-hospital death, vascular complications, transfusion, postprocedure myocardial infarction, stroke, and a combined major cardiovascular adverse event (MACE) end point including myocardial infarction, death, stroke, emergency coronary artery bypass grafting, and repeated PCI at the same site. Independent predictors of adverse outcomes were identified using multivariate logistic regression analysis. RESULTS: Compared with men, women were older, had a higher prevalence of comorbidities, and had a significantly higher frequency of adverse outcomes after PCI. After adjustment for baseline demographics, comorbidities, clinical presentation, and lesion characteristics, female gender was associated with an increased risk of in-hospital death, vascular complication, blood transfusion, stroke, and MACE. The relationship between female gender and increased risk of death and MACE was no longer present after further adjustment for kidney function and low body surface area. CONCLUSIONS: Differences in mortality rates between men and women no longer exist after PCI. However, our data suggest that technological advancements have not completely offset the relationship between gender and adverse outcomes after PCI.

RESUMEN

Background Cardiac rehabilitation is an established performance measure for adults with ischemic heart disease, but patient participation is remarkably low. Home-based cardiac rehabilitation (HBCR) may be more practical and feasible, but evidence regarding its efficacy is limited. We sought to compare the effects of HBCR versus facility-based cardiac rehabilitation (FBCR) on functional status in patients with ischemic heart disease. Methods and Results This was a pragmatic trial of 237 selected patients with a recent ischemic heart disease event, who enrolled in HBCR or FBCR between August 2015 and September 2017. The primary outcome was 3-month change in distance completed on a 6-minute walk test. Secondary outcomes included rehospitalization as well as patient-reported physical activity, quality of life, and self-efficacy. Characteristics of the 116 patients enrolled in FBCR and 121 enrolled in HBCR were similar, except the mean time from index event to enrollment was shorter for HBCR (25 versus 77 days; P<0.001). As compared with patients undergoing FBCR, those in HBCR achieved greater 3-month gains in 6-minute walk test distance (+95 versus +41 m; P<0.001). After adjusting for demographics, comorbid conditions, and indication, the mean change in 6-minute walk test distance remained significantly greater for patients enrolled in HBCR (+101 versus +40 m; P<0.001). HBCR participants reported greater improvements in quality of life and physical activity but less improvement in exercise self-efficacy. There were no deaths or cardiovascular hospitalizations. Conclusions Patients enrolled in HBCR achieved greater 3-month functional gains than those enrolled in FBCR. Our data suggest that HBCR may safely derive equivalent benefits in exercise capacity and overall program efficacy in selected patients.

RESUMEN

Background The lack of diversity in the cardiovascular physician workforce is thought to be an important driver of racial and sex disparities in cardiac care. Cardiology fellowship program directors play a critical role in shaping the cardiology workforce. Methods and Results To assess program directors' perceptions about diversity and barriers to enhancing diversity, the authors conducted a survey of 513 fellowship program directors or associate directors from 193 unique adult cardiology fellowship training programs. The response rate was 21% of all individuals (110/513) representing 57% of US general adult cardiology training programs (110/193). While 69% of respondents endorsed the belief that diversity is a driver of excellence in health care, only 26% could quote 1 to 2 references to support this statement. Sixty-three percent of respondents agreed that "our program is diverse already so diversity does not need to be increased." Only 6% of respondents listed diversity as a top 3 priority when creating the cardiovascular fellowship rank list. Conclusions These findings suggest that while program directors generally believe that diversity enhances quality, they are less familiar with the literature that supports that contention and they may not share a unified definition of "diversity." This may result in diversity enhancement having a low priority. The authors propose several strategies to engage fellowship training program directors in efforts to diversify cardiology fellowship training programs.

RESUMEN

Background: In the U.S. civilian population, sex differences have been identified in cardiovascular health; these differences have been used to inform care. Our objective is to determine if the same sex differences are present in Veterans who use the Department of Veterans Affairs (VA) Health Care System given the additional stressors associated with military service. Materials and Methods: Cardiovascular disease (CVD) risk factors and conditions among women and men Veterans using VA in fiscal year (FY) 2014 were identified through the presence of International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes in VA administrative records. ICD-9-CM codes were grouped into conditions; prevalence was examined by gender overall, by age, and by race/ethnicity. Results: Within the FY 2014 cohort of VA Veteran patients included in this analysis, 7.1% (n = 412,901) were women and 92.9% were men (n = 5,376,749). Compared with men, women in this cohort were younger and more ethnically diverse. Overall, women were less likely to have traditional CVD risk factors, but more likely to have a nontraditional CVD risk factor (depression) compared with men. Women had higher odds of chest pain/angina (adjusted odds ratio [AOR] 1.03, confidence interval [95% CI] 1.02-1.05), palpitations (AOR 2.04; 95% CI 1.98-2.10), and valvular disease (AOR 1.05; 95% CI 1.02-1.08), but lower odds of coronary artery disease (AOR 0.29; 95% CI 0.29-0.30), acute MI (AOR 0.46; 95% CI 0.43-0.49), and heart failure (AOR 0.55; 95% CI 0.53-0.56) compared with men, overall. Conclusions: In age-adjusted comparisons, sex differences in the prevalence of CVD risk factors and conditions among the VA Veteran patient population was similar in that seen in the civilian population with a few exceptions.

RESUMEN

OBJECTIVES: The authors sought to determine the factors that influence fellows-in-training (FITs) to pursue a career in interventional cardiology (IC) and how these differ by sex. BACKGROUND: Despite increases in the proportion of women across numerous medical and surgical specialties over the last decade, IC still ranks at the bottom in terms of representation of women. It is unclear why this maldistribution persists. METHODS: An online survey of cardiovascular FITs was conducted under the direction of the American College of Cardiology Women in Cardiology Leadership Council to assess FIT perspectives regarding subspecialty choices. RESULTS: Of 574 respondents, 33% anticipated specializing in IC. Men were more likely to choose IC than women (39% men, 17% women, odds ratio: 3.98 [95% confidence interval: 2.38 to 6.68]; p < 0.001). Men were more likely to be married (p = 0.005) and have children (p = 0.002). Among married FITs, male IC FITs were more likely to have spouses who do not work (p = 0.003). Although men were more likely to be influenced by positive attributes to pursue IC, women were significantly more likely to be influenced negatively against pursuing the field by attributes including greater interest in another field (p = 0.001), little job flexibility (p = 0.02), physically demanding nature of job (p = 0.004), radiation during childbearing (p < 0.001), "old boys' club" culture (p < 0.001), lack of female role models (p < 0.001), and sex discrimination (p < 0.001). CONCLUSIONS: Many factors uniquely dissuade women from pursuing IC compared with men, largely related to the culture of IC as a subspecialty. Targeted resolution of these specific factors may provide the most impact in reducing sex imbalances in the field.

RESUMEN

This document is the second of 2 companion appropriate use criteria (AUC) documents developed by the American College of Cardiology, American Association for Thoracic Surgery, American Heart Association, American Society of Echocardiography, American Society of Nuclear Cardiology, Heart Rhythm Society, Society for Cardiovascular Angiography and Interventions, Society of Cardiovascular Computed Tomography, Society for Cardiovascular Magnetic Resonance, and Society of Thoracic Surgeons. The first document1 addresses the evaluation and use of multimodality imaging in the diagnosis and management of valvular heart disease, whereas this document addresses this topic with regard to structural (nonvalvular) heart disease. While dealing with different subjects, the 2 documents do share a common structure and feature some clinical overlap. The goal of the companion AUC documents is to provide a comprehensive resource for multimodality imaging in the context of structural and valvular heart disease, encompassing multiple imaging modalities. Using standardized methodology, the clinical scenarios (indications) were developed by a diverse writing group to represent patient presentations encountered in everyday practice and included common applications and anticipated uses. Where appropriate, the scenarios were developed on the basis of the most current American College of Cardiology/American Heart Association Clinical Practice Guidelines. A separate, independent rating panel scored the 102 clinical scenarios in this document on a scale of 1 to 9. Scores of 7 to 9 indicate that a modality is considered appropriate for the clinical scenario presented. Midrange scores of 4 to 6 indicate that a modality may be appropriate for the clinical scenario, and scores of 1 to 3 indicate that a modality is considered rarely appropriate for the clinical scenario. The primary objective of the AUC is to provide a framework for the assessment of these scenarios by practices that will improve and standardize physician decision making. AUC publications reflect an ongoing effort by the American College of Cardiology to critically and systematically create, review, and categorize clinical situations in which diagnostic tests and procedures are utilized by physicians caring for patients with cardiovascular diseases. The process is based on the current understanding of the technical capabilities of the imaging modalities examined.

RESUMEN

BACKGROUND: The optimal hydration strategy for prevention of contrast-induced acute kidney injury (AKI) remains unknown. The purpose of this meta-analysis is to compare the effectiveness of normal saline (NS) versus sodium bicarbonate hydration (NaHCO(3)) for prevention of contrast-induced AKI. METHODS: We performed a meta-analysis of randomized controlled trials that compared saline-based hydration with sodium bicarbonate-based hydration regimen for prophylaxis of contrast-induced AKI. The literature search included MEDLINE, EMBASE, and Cochrane databases (2000 to October 2007); conference proceedings; and bibliographies of retrieved articles. Information was extracted on study design, sample characteristics, and interventions. Random-effects models were used to calculate summary risk ratios for contrast-induced AKI, need for hemodialysis, and death. RESULTS: Seven trials with 1,307 subjects were included. Preprocedural hydration with sodium bicarbonate was associated with a significant decrease in the rate of contrast-induced AKI (5.96% in the NaHCO(3) arm versus 17.23% in the NS arm, summary risk ratio 0.37, 95% CI 0.18-0.714, P = .005). There was no difference in the rates of postprocedure hemodialysis or death. Formal testing revealed moderate heterogeneity and a strong likelihood of publication bias. CONCLUSIONS: Although sodium bicarbonate hydration was found to be superior to NS in prevention of contrast-induced AKI, these results are in the context of study heterogeneity and, likely, publication bias. An adequately powered randomized controlled trial is warranted to define the optimal hydration strategy in patients at high risk of contrast-induced AKI who are scheduled to undergo contrast administration.

RESUMEN

BACKGROUND: This study was designed to determine whether overweight or obese status is independently associated with myocardial flow reserve (MFR), an established predictor of cardiovascular mortality, in a group of postmenopausal women with no previous cardiovascular disease. Postmenopausal women are the largest group of overweight and physically inactive individuals in the United States. Increased body mass index (BMI) is consistently associated with increased cardiovascular mortality in this population. Whether this is because of obesity itself or the accompanying increase in cardiovascular risk factors (CRFs) remains controversial. METHODS: We examined the relationship of myocardial blood flow (MBF), coronary vascular resistance, and MFR to BMI in 60 postmenopausal women with no coronary heart disease. Subjects underwent dynamic N-13 ammonia positron emission tomography for the measurement of MBF and MFR. Baseline demographics, CRF, and hemodynamic parameters were recorded for each subject. Datasets were divided into 3 groups according to BMI: normal (18 to 24), overweight (25 to 29), and obese (>or=30). RESULTS: The overweight and obese groups showed significantly higher resting MBF and lower MFR than the normal-weight group (both P < .001), even after adjusting for CRF. A further analysis of subjects without any CRF (n = 35) showed that the MFR remained significantly lower in the obese compared with normal-weight subjects (P = .05). Levels of known markers of vascular inflammation (high-sensitivity C-reactive protein and homocysteine) and high-density lipoprotein cholesterol levels correlated with declining MFR. CONCLUSIONS: These findings provide a mechanistic link between obesity and coronary heart disease in this population.

RESUMEN

BACKGROUND: Despite advances in the representation of women in medical training, women continue to be underrepresented in cardiology, academic medicine, and more specifically, in senior positions within academic medicine. Identifying disparities in research productivity and acknowledgment can highlight barriers to female representation in academic cardiology leadership, as well as in academic promotion. METHODS AND RESULTS: This bibliometric analysis included all authors of original research articles between 1980 and 2017 from 3 high-impact cardiology journals ( Journal of the American College of Cardiology, Circulation, and European Heart Journal). We identified 71 345 unique authors of 55 085 primary research articles during our study period. Female authors accounted for 33.1% of all authors; however, they represented only 26.7% of first authors and 19.7% of senior authors. Looking at the most prolific authors within this time period, female authors were not well represented, accounting for only 5% of the top 100 authors. Articles with a female senior author had more female middle authors than articles with a male senior author (mean 1.41 versus 0.97, P<0.001) and were more likely to have a female first author (0.37 versus 0.18, P<0.001). There was an increased representation of female authors as first and senior authors compared with the total number of articles with female authors over time ( P<0.001 for trend); however, female senior authorship rates continued to lag first authorship rates. CONCLUSIONS: Using a large database of published manuscripts, we found that female representation in published cardiology research has increased over the past 4 decades. However, women continue to be not well represented as first authors, senior authors, and in the number of publications. When women were senior authors, they published more articles with female first authors and had more female authors. In addition to recruiting more women into the field of cardiology, additional work is needed to identify and address barriers to academic advancement for female physician-scientists.

RESUMEN

Cardiac MRI tagging is a valuable technique for evaluating regional heart function. Currently, there are a number of different techniques for analyzing the tagged images. Specifically, k-space-based analysis techniques showed to be much faster than image-based techniques, where harmonic-phase (HARP) and sine-wave modeling (SinMod) stand as two famous techniques of the former group, which are frequently used in clinical studies. In this study, we compared HARP and SinMod and studied inter-observer variability between the two techniques for evaluating myocardial strain and apical-to-base torsion in numerical phantom, nine healthy controls, and thirty diabetic patients. Based on the ground-truth numerical phantom measurements (strain = -20% and rotation angle = -4.4°), HARP and SinMod resulted in overestimation (in absolute value terms) of strain by 1% and 5% (strain values), and of rotation angle by 0.4° and 2.0°, respectively. For the in-vivo results, global strain and torsion ranges were -10.6% to -35.3% and 1.8°/cm to 12.7°/cm in patients, and -17.8% to -32.7% and 1.8°/cm to 12.3°/cm in volunteers. On average, SinMod overestimated strain measurements by 5.7% and 5.9% (strain values) in the patients and volunteers, respectively, compared to HARP, and overestimated torsion measurements by 2.9°/cm and 2.5°/cm in the patients and volunteers, respectively, compared to HARP. Location-wise, the ranges for basal, mid-ventricular, and apical strain in patients (volunteers) were -8.4% to -31.5% (-11.6% to -33.3%), -6.3% to -37.2% (-17.8% to -33.3%), and -5.2% to -38.4% (-20.0% to -33.2%), respectively. SinMod overestimated strain in the basal, mid-ventricular, and apical slices by 4.7% (5.7%), 5.9% (5.5%), and 8.9% (6.8%), respectively, compared to HARP in the patients (volunteers). Nevertheless, there existed good correlation between the HARP and SinMod measurements. Finally, there were no significant strain or torsion measurement differences between patients and volunteers. There existed good inter-observer agreement, as all measurement differences lied within the Bland-Altman ±â€¯2 standard-deviation (SD) difference limits. In conclusion, despite the consistency of the results by either HARP or SinMod and acceptable agreement of the generated strain and torsion patterns by both techniques, SinMod systematically overestimated the measurements compared to HARP. Under current operating conditions, the measurements from HARP and SinMod cannot be used interchangeably.

RESUMEN

Importance: Few data exist on internal medicine trainees' selection of cardiology training, although this is important for meeting future cardiology workforce needs. Objective: To discover trainees' professional development preferences and perceptions of cardiology, and their relationship to trainees' career choice. Design, Setting, and Participants: We surveyed trainees to discover their professional development preferences and perceptions of cardiology and the influence of those perceptions and preferences on the trainees' career choices. Participants rated 38 professional development needs and 19 perceptions of cardiology. Data collection took place from February 2009, through January 2010. Data analysis was conducted from May 2017 to December 2017. Main Outcomes and Measures: Multivariable models were used to determine the association of demographics and survey responses with prospective career choice. Results: A total of 4850 trainees were contacted, and 1123 trainees (of whom 625 [55.7%] were men) in 198 residency programs completed surveys (23.1% response; mean [SD] age, 29.4 [3.5] years). Principal component analysis of survey responses resulted in 8-factor and 6-factor models. Professional development preferences in descending order of significance were stable hours, family friendliness, female friendliness, the availability of positive role models, financial benefits, professional challenges, patient focus, and the opportunity to have a stimulating career. The top perceptions of cardiology in descending order of significance were adverse job conditions, interference with family life, and a lack of diversity. Women and future noncardiologists valued work-life balance more highly and had more negative perceptions of cardiology than men or future cardiologists, who emphasized the professional advantages available in cardiology. Professional development factors and cardiology perceptions were strongly associated with a decision to pursue or avoid a career in cardiology in both men and women. Conclusions and Relevance: Alignment of cardiology culture with trainees' preferences and perceptions may assist efforts to ensure the continued attractiveness of cardiology careers and increase the diversity of the cardiology workforce.
