RESUMO
The practice patterns and outcomes of protected left main (PLM) and unprotected left main (ULM) percutaneous coronary intervention (PCI) are not well defined in contemporary US clinical practice. Data were collected from all Veteran Affairs catheterization laboratories participating in the Clinical Assessment Reporting and Tracking Program between 2009 and 2019. The analysis included 4,351 patients who underwent left main PCI, of whom 1,306 pairs of PLM and ULM PCI were included in a propensity-matched cohort. Selected temporal trends were also assessed. The primary outcome was major adverse cardiovascular event (MACE) outcomes at 1 year, which was defined as a composite of all-cause mortality, rehospitalization for myocardial infarction (MI), rehospitalization for stroke, or urgent revascularization. Patients who underwent ULM PCI compared with patients who underwent PLM PCI were older (age 71.5 vs 69.2 years, p <0.001), more clinically complex, and more likely to present with acute coronary syndrome. In the propensity-matched cohort, radial access was used more often for ULM PCI (21% [273] vs 14% [185], p <0.001) and ULM PCI was more likely to involve the left main bifurcation (22% vs 14%, p = 0.003) and require mechanical circulatory support (10% [134] vs 1% [17], p <0.001). The 1-year MACEs occurred more frequently with ULM PCI than PLM PCI (22% [289] vs 16% [215], p ≤0.001) and all-cause mortality was also higher (16% [213] vs 10% [125], p ≤0.001). In the matched cohort, there was a low incidence of rehospitalization for MI (4% [48] ULM vs 4% [48] PLM, p = 1.000) or revascularization (7% [94] ULM vs 6% [84] PLM, p = 0.485). In this real-world experience, patients who underwent PLM PCI had better 1-year outcomes than those who underwent ULM PCI; however, in both groups, there was a high rate of mortality and MACEs at 1 year despite a relatively low rate of MI or revascularization.

BACKGROUND: We assessed trends in novel cardiovascular medication utilization in US Veterans Affairs (VA) for angiotensin receptor-neprilysin inhibitors (ARNI), sodium-glucose cotransporter-2 Inhibitors (SGLT2i), and glucagon-like peptide-1 receptor agonists (GLP-1 RA). METHODS: We retrospectively identified cohorts from 114 VA hospitals with admission for prevalent 1) systolic heart failure (HF, N = 82,375) or 2) coronary artery disease and diabetes (CAD+T2D, N = 74,209). Site-level data for prevalent filled prescriptions were assessed at hospital admission, discharge, or within 6 months of discharge. Variability among sites was estimated with median odds ratios (mOR), and within-site Pearson correlations of utilization of each medication class were calculated. Site- and patient-level characteristics were compared by high-, mixed-, and low-utilizing sites. RESULTS: ARNI and SGTL2i use for HF increased from <5% to 20% and 21%, respectively, while SGTL2i or GLP-1 RA use for CAD+T2D increased from <5% to 30% from 2017 to 2021. Adjusted mOR and 95% confidence intervals for ARNI, SGTL2i for HF, and SGTL2i or GLP-1 RA for CAD+T2D were 1.73 (1.64-1.91), 1.72 (1.59-1.81), and 1.53 (1.45-1.62), respectively. Utilization of each medication class correlated poorly with use of other novel classes (Pearson <0.38 for all). Higher patient volume, number of beds, and hospital complexity correlated with high-utilizing sites. CONCLUSIONS: Utilization of novel medications has increased over time but remains suboptimal for US Veterans with HF and CAD+T2D, with substantial site-level heterogeneity despite a universal medication formulary and low out-of-pocket costs for patients. Future work should include further characterization of hospital- and clinician-level practice patterns to serve as targets to increase implementation.

Background: Practice patterns and outcomes of protected left main (PLM) and unprotected left main (ULM) percutaneous coronary intervention (PCI), as well as the differences between these types of PCI, are not well defined in real-world clinical practice. Methods: Data collected from all Veteran Affairs (VA) catheterization laboratories participating in the Clinical Assessment Reporting and Tracking Program between 2009 and 2019. The analysis included 4,351 patients undergoing left main PCI, of which 1,306 pairs of PLM and ULM PCI were included in a propensity matched cohort. Patients and procedural characteristics were compared between PLM and ULM PCI. Temporal trends were also assessed. Peri-procedural and one-year major adverse cardiovascular events (MACE) were compared using cumulative incidence plots. The primary outcome was MACE outcomes at 1-year, which was defined as a composite of all-cause mortality, rehospitalization for myocardial infarction (MI), rehospitalization for stroke or urgent revascularization. Results: ULM PCI patients in comparison to PLM PCI were older (71.5 vs 69.2; P < 0.001), more clinically complex and more likely to present with ACS. In the propensity matched cohort, radial access was used more often for ULM PCI (21% [273] vs. 14% [185], P < 0.001), and ULM PCI was more likely to involve the LM bifurcation (22% vs 14%; P = 0.003) and require mechanical circulatory support (10% [134] vs 1% [17]; P <0.001). One-year MACE occurred more frequently with ULM PCI compared to PLM PCI (22% [289] vs. 16% [215]; P = < 0.001) and all-cause mortality was also higher (16% [213] vs. 10% [125]; P = < 0.001). In the matched cohort there was a low incidence of rehospitalization for MI (4% [48] ULM vs. 4% [48] PLM; P = 1.000) or revascularization (7% [94] ULM vs. 6% [84] PLM; P = 0.485). Conclusions: Veterans undergoing PLM PCI had better one-year outcomes than those undergoing ULM PCI, but in both groups there was a high rate of mortality and MACE at one-year despite a relatively low rate of MI or revascularization.
RESUMO
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.

Background Clinical characteristics and outcomes in people living with HIV (PLWH) undergoing percutaneous coronary intervention (PCI) remain poorly described. We sought to compare real-world treatment of coronary artery disease, as well as patient and procedural factors and outcomes after PCI between PLWH and uninfected controls. Methods and Results We utilized procedural registry data from the Veterans Affairs Clinical Assessment, Reporting, and Tracking Program between January 1, 2009 and December 31, 2019 to analyze patients with obstructive coronary artery disease on angiography. In the PCI subgroup, we used inverse probability of treatment weighting and applied Cox proportional hazards to evaluate the association of HIV serostatus with outcomes, including all-cause mortality at 5 years. Among 184 310 patients with obstructive coronary artery disease, treatment strategy was similar between PLWH and controls-35.7% versus 34.2% PCI, 13.6% versus 15% coronary artery bypass grafting, and 50.7% versus 50.8% medical therapy. The PCI cohort consisted of 546 (0.9%) PLWH and 56 811 (99.1%) controls. PLWH undergoing PCI had well-controlled HIV disease, and compared with controls, were younger, more likely to be Black, had fewer traditional risk factors, more acute coronary syndrome, less extensive coronary artery disease, and similar types of stents and P2Y12 therapy. However, PLWH experienced worse survival as early as 6 months post-PCI, which persisted over time and amounted to a 21% increased mortality risk by 5 years (hazard ratio, 1.21 [95% CI, 1.03-1.42; P=0.02]). Conclusions Despite well-controlled HIV disease, a more favorable overall cardiovascular risk profile, and similar PCI procedural metrics, PLWH still have significantly worse long-term survival following PCI than controls.

BACKGROUND: Anatomical scoring systems have been used to assess completeness of revascularization but are challenging to apply to large real-world datasets. OBJECTIVES: The aim of this study was to assess the prevalence of complete revascularization and its association with longitudinal clinical outcomes in the U.S. Department of Veterans Affairs (VA) health care system using an automatically computed anatomic complexity score. METHODS: Patients undergoing percutaneous coronary intervention (PCI) between October 1, 2007, and September 30, 2020, were identified, and the burden of prerevascularization and postrevascularization ischemic disease was quantified using the VA SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) score. The association between residual VA SYNTAX score and long-term major adverse cardiovascular events (MACE; death, myocardial infarction, repeat revascularization, and stroke) was assessed. RESULTS: A total of 57,476 veterans underwent PCI during the study period. After adjustment, the highest tertile of residual VA SYNTAX score was associated with increased hazard of MACE (HR: 2.06; 95% CI: 1.98-2.15) and death (HR: 1.50; 95% CI: 1.41-1.59) at 3 years compared to complete revascularization (residual VA SYNTAX score = 0). Hazard of 1- and 3-year MACE increased as a function of residual disease, regardless of baseline disease severity or initial presentation with acute or chronic coronary syndrome. CONCLUSIONS: Residual ischemic disease was strongly associated with long-term clinical outcomes in a contemporary national cohort of PCI patients. Automatically computed anatomic complexity scores can be used to assess the longitudinal risk for residual ischemic disease after PCI and may be implemented to improve interventional quality.

OBJECTIVE: To compare rates of successful tympanic membrane (TM) closure in primary pediatric tympanoplasty between various autologous and non-autologous tissues. METHODS: A retrospective chart review was performed examining all primary pediatric tympanoplasties over a 20-year period at a single institution. RESULTS: In 564 pediatric tympanoplasties, no statistically significant difference existed between success rates of autologous and non-autologous grafts (pâ=â0.083). Compared with fascia, the hazard ratios (and 95% confidence intervals [CI]) for failure for each graft were as follows: human pericardial collagen (HR 0.90, CI 0.54-1.50, pâ=â0.680), porcine submucosal collagen (HR 1.07, CI 0.56-2.05, pâ=â0.830), human acellular dermal collagen (HR 1.66, CI 0.95-2.87, pâ=â0.073), and "multiple grafts" (HR 0.72, CI 0.26-1.98, pâ=â0.520). Survival curves demonstrated that 75% of graft failures occurred by 6âmonths after surgery, the rest occurring between 6 and 12âmonths postoperatively. Larger perforations encompassing more than or equal to 50% of the TM had lower success rates (HR 1.50, CI 1.02-2.21, pâ=â0.041) than smaller perforations encompassing less than 50% of the TM. Age was not correlated with success (HR 0.98, CI 0.93-1.03, pâ=â0.390). CONCLUSION: This study found that non-autologous collagen grafts provide equivalent rates of healing when compared with autologous tissue in primary pediatric tympanoplasty. In addition to the potential for reduced operative time and donor site morbidity, these materials provide a viable graft alternative in fascia-depleted ears.Level of Evidence: Level 4.

Background High-risk percutaneous coronary intervention (HR-PCI) is increasingly common among contemporary patients with coronary artery disease. Experts have advocated for a collaborative 2-operator approach to support intraprocedural decision-making for these complex interventions. The impact of a second operator on patient and procedural outcomes is unknown. Methods and Results Patients who underwent HR-PCI from 2015 to 2018 within the Veterans Affairs Healthcare System were identified. Propensity-matched cohorts were generated to compare the outcomes following HR-PCI performed by a single or multiple (≥2) operators. The primary end point was the 12-month rate of major adverse cardiovascular events. We identified 6672 patients who underwent HR-PCI during the study period; 6211 (93%) were treated by a single operator, and 461 (7%) were treated by multiple operators, with a nonsignificant trend toward increased multioperator procedures over time. A higher proportion of patients treated by multiple operators underwent left main (10% versus 7%, P=0.045) or chronic total occlusion intervention (11% versus 5%, P<0.001). Lead interventionalists participating in multioperator procedures practiced at centers with higher annual HR-PCI volumes (124±71.3 versus 111±69.2; standardized mean difference, 0.197; P<0.001) but otherwise performed a similar number of HR-PCI procedures per year (34.4±35.3 versus 34.7±30.7; standardized mean difference, 0.388; P=0.841) compared with their peers performing single-operator interventions. In a propensity-matched cohort, there was no significant difference in major adverse cardiovascular events (32% versus 30%, P=0.444) between patients who underwent single-operator versus multioperator HR-PCI. Adjusted analyses accounting for site-level variance showed no significant differences in outcomes. Conclusions Patients who underwent multioperator HR-PCI had similar outcomes compared with single-operator procedures. Further studies are needed to determine if the addition of a second operator offers clinical benefits to a subset of HR-PCI patients undergoing left main or chronic total occlusion intervention.

BACKGROUND: Revascularization of ischemic cardiomyopathy by coronary artery bypass grafting has been shown to improve survival among patients with left ventricular ejection fraction (LVEF) ≤35%, but the role of percutaneous coronary intervention (PCI) in this context is incompletely described. This study sought to evaluate the effect of PCI on mortality and hospitalization among patients with stable coronary artery disease and reduced left ventricular ejection fraction. METHODS: We performed a retrospective analysis comparing PCI with medical therapy among patients with ischemic cardiomyopathy in the Veterans Affairs Health Administration. Patients with angiographic evidence of 1 or more epicardial stenoses amenable to PCI and LVEF ≤35% were included in the analysis. Outcome data were determined by VA and non-VA data sources on mortality and hospital admission. RESULTS: From 2008 through 2015, a study sample of 4,628 patients was identified, of which 1,322 patients underwent ad hoc PCI. Patients were followed to a maximum of 3 years. Propensity score weighted landmark analysis was used to evaluate the primary and secondary outcomes. The primary outcome of all-cause mortality was significantly lower in the PCI cohort compared with medical therapy (21.6% vs 30.0%, P <.001). The secondary outcome of all-cause rehospitalization or death was also lower in the PCI cohort (76.5% vs 83.8%, P <.001). CONCLUSIONS: In this retrospective analysis of patients with ischemic cardiomyopathy with coronary artery disease amenable to PCI and LVEF ≤35%, revascularization by PCI was associated with decreased all-cause mortality and decreased all-cause death or rehospitalization.

Comparisons of the outcomes of patients with myocardial infarction with nonobstructive coronary artery disease (MINOCA) and patients with nonobstructive coronary artery disease (CAD) without myocardial infarction (MI) are limited. Here we compare the outcomes of patients with MINOCA and patients with nonobstructive CAD without MI and assess the influence of medical therapy on outcomes in these patients. Veterans who underwent coronary angiography between 2008 to 2017 with nonobstructive CAD were divided into those with or without pre-procedural troponin elevation. Patients with prior revascularization, heart failure, or who presented with cardiogenic shock, STEMI, or unstable angina were excluded. After propensity matching, outcomes were compared between groups. The primary outcome was major adverse cardiovascular events (MACE: mortality, myocardial infarction, and revascularization) within one year: 3,924 patients with nonobstructive CAD and a troponin obtained prior to angiography were identified (n=1,986 with elevated troponin) and restricted to 1,904 patients after propensity-matching. There was a significantly higher risk of MACE among troponin-positive patients compared with those with a negative troponin (HR 2.37; 95% CI, 1.67 to 3.34). Statin (HR 0.32; 95% CI, 0.22 to 0.49) and ACE inhibitor (HR 0.49; 95% CI, 0.32 to 0.75) therapy after angiography was associated with decreased MACE, while P2Y12 inhibitor, calcium-channel and beta-blocker therapy were not associated with outcomes. In conclusion, Veterans with MINOCA are at increased risk for MACE compared with those with nonobstructive CAD and negative troponin at the time of angiography. Specific medications were associated with a reduction in MACE, suggesting an opportunity to explore novel approaches for secondary prevention in this population.

BACKGROUND: Professional society consensus statements articulate the clinical and anatomic complexity of patients that may undergo percutaneous coronary intervention (PCI) without on-site cardiothoracic surgery, although compliance with these recommendations has not been assessed. We sought to evaluate the clinical and anatomic complexity of patients undergoing PCI with and without cardiothoracic surgery on-site. METHODS: We identified all patients undergoing PCI in the Veterans Affairs health care system between October 2009 and September 2017. The clinical and anatomic complexity of patients treated at sites with or without cardiothoracic surgery was evaluated with a comparative interrupted time series, and mortality was ascertained in a propensity-matched cohort. RESULTS: We identified 75 564 patients who underwent PCI, with the majority (53 708, 71%) treated at sites with cardiothoracic surgery. The overall clinical complexity was statistically greater for those treated at sites with cardiothoracic surgery (National Cardiovascular Data Registries CathPCI: 18.4) compared with those at sites without (17.8, P<0.001) throughout the study, with similar annual increases in complexity before (2% versus 3%; P=0.107) and after (3% versus 3%; P=0.704) January 2014. The anatomic complexity of patients treated was also statistically greater (Veterans Affairs SYNTAX: 11.0 versus 10.2; P<0.001) and increased at comparable rates (2% versus 1%, P=0.731) before 2014. After publication of the consensus statement, anatomic complexity declined at sites with cardiothoracic surgery (-2%) but increased at sites without on-site surgery (5%, P=0.025) such that it was similar at the end of the study (P=0.622). Referrals for emergent cardiothoracic surgery were rare regardless of treatment venue (61, 0.08%) and the hazard for mortality was similar (hazard ratio, 0.883 [95% CI, 0.662-1.176]) after propensity matching. CONCLUSIONS: There are minor differences in complexity of patients undergoing coronary intervention at sites with and without cardiothoracic surgery. Clinical outcomes are similar regardless of treatment venue, suggesting an opportunity to improve access to complex interventional care without sacrificing quality.

The COVID-19 pandemic has required many clinical and translational scientists and staff to work remotely to prevent the spread of the virus. To understand the impact on research programs, we assessed barriers to remote work and strategies implemented to support virtual engagement and productivity. A mixed-methods RedCap survey querying the remote work experience was emailed to Colorado Clinical and Translational Sciences Institute (CCTSI) scientists and staff in April 2020. Descriptive analyses, Fisher's Exact tests, and content analysis were conducted. Respondents (n = 322) were primarily female (n = 240; 75%), 21-73 years old (mean = 42 years) with a PhD (n = 139; 44%) or MD (n = 56; 55%). Prior to COVID-19, 77% (n = 246) never or rarely (0-1 day a week) worked remotely. Remote work somewhat or greatly interfered with 76% (n = 244) of researchers' programs and 71% (n = 231) reported slowing or stopping their research. Common barriers included missing interactions with colleagues (n = 198; 62%) and the absence of routines (n = 137; 43%). Strategies included videoconferencing (n = 283; 88%), altering timelines and expectations (n = 180; 56%). Scientists and staff experienced interference with their research when they shifted to remote work, causing many to slow or stop research programs. Methods to enhance communication and relationships, support productivity, and collectively cope during remote work are available.
