Clinical presentation, outcomes, and threshold for repair by sex in degenerative saccular vs fusiform aneurysms in the descending thoracic aorta.
The purpose of this study was to explore variations in presentation, treatment, and outcomes between saccular thoracic aortic aneurysms (TAAs) and fusiform TAAs in the descending thoracic aorta. The researchers also explored the need for sex-specific treatment thresholds for TAAs. The study found that among 655 emergent/urgent thoracic endovascular aneurysm repairs (TEVARs), 37% were performed for saccular TAAs, whereas among 1352 elective TEVARs, 35% had saccular TAA morphology. Compared with fusiform TAAs, saccular TAAs more frequently underwent emergent/urgent (ruptured/symptomatic) TEVAR below the repair threshold in both females and males. Among patients with emergent/urgent fusiform TAAs, females presented at smaller diameters compared with males, yet there was no variance in preoperative aneurysm diameter among patients with saccular TAAs. Emergent/urgent treated saccular TAAs had similar postoperative outcomes and 5-year mortality compared with fusiform TAAs. In the elective cohort, patients with saccular TAAs had comparable postoperative mortality compared with those with fusiform TAAs, but a lower rate of postoperative spinal cord ischemia. additionally, patients with saccular TAAs had a higher rate of 5-year mortality compared with their fusiform counterparts.

Cardiac rehabilitation reduces two-year mortality after coronary artery bypass grafting.
This study analyzed the outcome of cardiac rehabilitation (CR) use for patients who have undergone coronary revascularization procedures. The study looked at Medicare fee-for-service claims linked to surgical data patients discharged alive following isolated coronary artery bypass grafting (CABG) from January 2015 to October 2019. A total of 3,848/6,412 (60.0%) of patients were enrolled in CR for an average of 23.2 sessions with 770/6,412 (12.0%) completing all recommended 36 sessions. Predictors of post-discharge CR use included increasing age, discharge to home (vs extended care facility), and shorter length of stay. Unadjusted and inverse probability treatment weighting (IPTW) analyses showed significant reduction in 2-year mortality in CR users as compared to CR non-users (unadjusted 9.4%).

Relationship between community-level distress and cardiac rehabilitation participation, facility access, and clinical outcomes after inpatient coronary revascularization.
The purpose of this retrospective cohort study was to assess the association between community-level distress and cardiac rehabilitation (CR) participation, access to CR facilities, and clinical outcomes. The study included a 100% sample of Medicare beneficiaries undergoing inpatient coronary revascularization between July 2016 and December 2018. Community-level distress was defined by the researchers as using the Distressed Community Index quintile at the beneficiary zip code level, with the first and fifth quintiles representing prosperous and distressed communities, respectively. The study found that any CR use was lower for beneficiaries in distressed compared with prosperous communities (26.0% versus 46.1%), which was significant after multivariable adjustment. 23.7% of beneficiaries had a CR facility within their zip code, which increased from 16.3% in prosperous communities to 26.6% in distressed communities. Any CR utilization was related with absolute reductions in mortality, all-cause hospitalization, and acute myocardial infarction hospitalization, which were comparable across each Distressed Community Index quintiles.

Early versus delayed thoracic endovascular aortic repair for blunt thoracic aortic injury: a propensity score-matched analysis.
This study examined the outcomes of ≤24 h) versus delayed (>24 h) thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI), taking the aortic injury severity into consideration. Current trauma surgery guidelines recommend delayed TEVAR. Patients undergoing TEVAR for BTAI in the American College of Surgeons Trauma Quality Improvement Program between 2016 and 2019 were included and then stratified into early (≤24 h) or delayed (>24 h). The cohort looked at included 1339 patients, of whom 1054 (79%) underwent early TEVAR. Compared with the delayed group, the early group had significantly less severe head injuries (early vs delayed; 25% vs 32%), fewer early interventions for AAS grade 1 occurred, and AAS grade 3 aortic injuries often were intervened upon within 24 hours (grade 1: 28% vs 47%; grade 3: 49% vs 23%). Compared with the delayed group, the early group had significantly higher in-hospital mortality (8.8% vs 4.4%, relative risk: 2.2, 95% CI: 1.1-4.4), alongside a shorter length of hospital stay (5.0 vs 10 days), a shorter intensive care unit length of stay (4.0 vs 11 days) and fewer days on the ventilator (4.0 vs 6.5 days). Regardless of the higher risk of acute kidney injury in the delayed group (3.3% vs 7.7%), no other differences in in-hospital complications were observed between the early and delayed group.

Outcomes associated with sodium-glucose cotransporter-2 inhibitor use in acute heart failure hospitalizations complicated by AKI.
This retrospective study examined the association of sodium-glucose cotransporter-2 inhibitor (SGLT2i) use with patients who have KDIGO-defined acute kidney injury (AKI) during acute heart failure (AHF) hospitalizations and their kidney function recovery at 14 days and 30 days using time-varying multivariable Cox-regression analyses. The study looked at 3305 adults hospitalized across 5 Yale New Haven Health Systems between January 2020 and May 2022 with AHF complicated by KDIGO-defined AKI. Of those individuals hospitalized with AHF and AKI, 356 received SGLT2i following AKI diagnosis either as initiation or continuation. The rate of renal recovery was not significantly different among those exposed and unexposed to SGLT2i following AKI (adjusted HR 0.94). SGLT2i exposure was associated with lower risk of 30-day mortality (adjusted HR 0.45). Rates of renal recovery were similar between the exposed and nonexposed cohorts regardless of the proximity of SGLT2i exposure to AKI diagnosis.

Association of direct oral anticoagulation management strategies with clinical outcomes for adults with atrial fibrillation.
This study investigated the impact of an anticoagulation management service (AMS) on clinical outcomes of adults with atrial fibrillation (AF). This retrospective cohort study was conducted in 3 Kaiser Permanente regions, with each region taking a slightly different approach to direct oral anticoagulant (DOAC) care. These approaches included (1) usual care (UC) by the prescribing clinician, (2) UC plus an automated population management tool (PMT), or (3) pharmacist-managed AMS care. The study included 44,746 adults with a diagnosis of AF who initiated DOAC or warfarin between August 2016 and January 1, 2020, 6182 in the UC model, 33,624 in the UC plus PMT care model, and 4939 in the AMS care model. Baseline characteristics (mean age, 73.1 years, 56.1% male, 67.2% non-Hispanic White, median CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years, diabetes, stroke, vascular disease, age 65-74 years, female sex] score of 3 [IQR, 2-5]) were well balanced after inverse probability of treatment weighting (IPTW). The cohort was followed over a median of 2 years, and patients who received the UC plus PMT or AMS care model did not have significantly better outcomes than those who received only UC.

Outcomes following thoracic endovascular aortic repair for blunt thoracic aortic injury stratified by Society for Vascular Surgery grade.
Researchers analyzed data on patients undergoing thoracic endovascular aortic repair (TEVAR) for blunt thoracic aortic injury (BTAI) within the Society for Vascular Surgery aortic injury grading system to assess its association with outcomes. Their findings indicated higher perioperative and 5-year mortality in TEVAR patients with grade 4 BTAI, but no association with the aortic injury grade after risk adjustment. More than 5% of TEVAR patients with BTAI had a grade 1 injury, with a significant rate of spinal cord ischemia potentially attributable to TEVAR; this proportion did not decrease over time. The researchers suggested that future efforts should focus on careful selection of patients with BTAI who will experience more benefit than harm from operative repair and prevent inadvertent use of TEVAR in low-grade injuries.

Distal embolic protection use during transfemoral carotid artery stenting is associated with improved in-hospital outcomes.
Researchers sought to assess in-hospital outcomes in patients who had undergone transfemoral carotid artery stenting (tfCAS) with and without embolic protection using a distal filter. Patients undergoing tfCAS were identified in the Vascular Quality Initiative and those who received proximal embolic balloon protection were excluded. Outcomes of interest were stroke, death, composite stroke/death, myocardial infarction, transient ischemic attack, and hyperperfusion syndrome. Results indicated that tfCAS performed without attempted distal embolic protection was associated with higher risk of in-hospital stroke and death; tfCAS after a failed attempt at filter placement had equivalent stroke/death to patients with no filter attempted, but higher risk of stroke/death compared with those with successfully placed filters. The researchers concluded that these findings support current Society for Vascular Surgery guidelines and, if a filter cannot be safely placed, alternative approaches to carotid revascularization should be considered.

Evaluating the implementation of patient-reported outcomes in heart failure clinic: a qualitative assessment.
This study evaluated clinician perceptions of the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12), a patient reported outcome (PRO) survey that captures symptom frequency, symptom burden, physical limitations, social limitations, and quality of life. The authors conducted interviews with cardiologists from 4 institutions across the United States and Canada (n=16) and observed clinic visits at 1 institution in Northern California (n=5). They conducted 2 rounds of interviews and did a qualitative analysis on (1) rapid analysis constructed around major themes related to the aims of the study and (2) content analysis with codes derived from the rapid analysis and implementation science. Most cardiologists reported the KCCQ-12 was acceptable, appropriate, and useful in clinical care. The survey was found to improve the consistency of patient history taking, focus patient-clinician conversations, collect a more accurate account of patient quality of life, track trends in patient well-being over time, and refine clinical decision-making.

Statin therapy is associated with improved perioperative outcomes and long-term mortality following carotid revascularization in the Vascular Quality Initiative.
This study evaluated the outcomes of carotid artery stenosis (CAS) patients using statin therapy before undergoing carotid revascularization in the Vascular Quality Initiative registry. The authors identified all patients who underwent carotid endarterectomy (CEA), transfemoral carotid artery stenting (tfCAS), or transcarotid artery revascularization (TCAR) in the Vascular Quality Initiative registry from January 2016 to September 2021. Compared with statin use, no statin use was associated with a higher risk of in-hospital stroke or death and 5-year mortality among CEA and tfCAS patients, although there was no significant difference in outcomes among TCAR patients.

The effect of supraceliac versus infraceliac landing zone on outcomes following fenestrated endovascular repair of juxta-/pararenal aortic aneurysms.
The purpose of this study was to assess perioperative outcomes in patients in the Vascular Quality Initiative who underwent juxta-/pararenal FEVAR with supraceliac vs infraceliac sealing. 1,486 Patients who received an elective FEVAR for juxta-/pararenal aortic aneurysms in the Vascular Quality Initiative between 2014 and 2021were identified and included.
The researchers defined supraceliac sealing as proximal sealing in aortic zone 5, or zone 6 with a celiac scallop/fenestration/branch or celiac occlusion. The study’s primary outcomes were perioperative and 3-year mortality, and secondary outcomes were completion endoleaks, in-hospital complications, and variables related with 3-year mortality. The study found that of the included patients, 84% underwent infraceliac sealing, and 16% underwent supraceliac sealing. Of the supraceliac patients, 60% had a celiac fenestration/branch, 31% had a celiac scallop, and 9.2% had a celiac occlusion (intentional or unintentional). Compared with infraceliac sealing, there were no differences after risk-adjusted analysis in perioperative mortality following supraceliac sealing. Supraceliac sealing was associated with lower odds of type-IA completion endoleaks, but higher odds of any complication including cardiac complications, lower extremity ischemia and acute kidney injury when compared with infraceliac sealing. The researchers concluded that supraceliac sealing was associated with lower risk of type IA endoleaks and similar mortality compared with sealing at an infraceliac level. The researchers advise that providers should be aware that supraceliac sealing was related with higher perioperative morbidity.

In-hospital outcomes after upper extremity versus transfemoral and transcarotid access for carotid stenting in the Vascular Quality Initiative.
This comparative study examined outcomes for treatment of patients at high risk of carotid endarterectomy using different approaches of carotid artery stenting (CAS). The study compared the effects of transradial or transbrachial (tr/tbCAS) versus more established transfemoral (tfCAS) or transcarotid (TCAR) CAS procedures. Patients were identified from the Quality Initiative registry from January 2016 to December 2021. Among 40,835 CAS identified patients, 962 underwent tr/tbCAS, 28,850 underwent tfCAS, and 21,033 underwent TCAR. Among matched patients who underwent tr/tbCAS versus tfCAS, there was no significant difference in the risk of stroke/death (4.1% vs 2.9), but tr/tbCAS was associated with a higher risk of death (2.4% vs 1.3). In the symptomatic subgroup, tr/tbCAS was associated with a higher risk of stroke/death (6.1% vs 3.9%) and death (3.6% vs 1.7%), but there were no differences in asymptomatic patients. After adjustment for Modified Rankin Scale in patients with preoperative stroke, there were no significant differences in stroke/death or death between groups.

Disparities in 5-year outcomes and imaging surveillance following elective endovascular repair of abdominal aortic aneurysm by sex, race, and ethnicity.
The purpose of this study was to identify variations in 5-year outcomes and imaging surveillance after elective endovascular aortic aneurysm repair (EVAR) by sex, race, and ethnicity and to examine possible mechanisms contributing to these variations. The primary outcome was 5-year aneurysm rupture. Secondary outcomes were 5-year reintervention and mortality, and having no aortic imaging follow-up from 6 to 24 months after EVAR. The study found that among 16,040 patients, 73% were White males, 18% were White females, 2.6% were Black males, 1.1% were Black females, 0.9% were Asian males, 0.2% were Asian females, 1.7% were Hispanic males, and 0.4% were Hispanic females. At 5 years, Black females had the highest rupture rates at 6.4% and white males had the lowest at 2.3%. Compared with White males, rupture rates were higher in White females, Black females, and Asian females. Among other groups, Black males had higher reintervention and both Black and Hispanic males had higher rates of no imaging follow-up. In adjusted analyses, White, Black, and Asian females remained at significantly higher risk for 5-year rupture. The researchers concluded that Black females had higher 5-year aneurysm rupture, reintervention, and mortality rates after elective EVAR as compared with White male patients, whereas White females had higher rupture, mortality and loss-to-imaging-follow-up compared to White male patients. Black males had higher reintervention and no imaging follow-up, and Asian females had higher rupture rates.

Outcomes after transcarotid artery revascularization stratified by preprocedural symptom status.
In this study, researchers examined contemporary perioperative outcomes in patients who underwent transcarotid artery revascularization (TCAR) stratified by specific preprocedural symptom status. Using data from the Vascular Quality Initiative, they found that, after TCAR, compared with asymptomatic status, a recent stroke and a recent hemispheric TIA were associated with higher stroke/death rates, whereas a recent ocular TIA was associated with similar stroke/death rates. In addition, a formerly symptomatic status was associated with higher stroke/death rates compared with an asymptomatic status. The researchers concluded that their findings suggested that classifying patients undergoing TCAR as symptomatic versus asymptomatic may be an oversimplification and that patients' specific preoperative neurologic symptoms should instead be used in risk assessment and outcome reporting for TCAR.

Racial and ethnic disparities in 3-year outcomes following infrainguinal bypass for chronic limb-threatening ischemia.
This study’s objective was to determine the differences in 3-year outcomes after open infrainguinal bypass for chronic limb-threatening ischemia (CLTI) stratified by race/ethnicity and explored the potential factors contributing to these differences to help determine reasons why outcomes are worse for racial and ethnic minorities. The authors identified all CLTI patients who had undergone primary open infrainguinal bypass in the Vascular Quality Initiative registry from 2003 to 2017 with linkage to Medicare claims through 2018 for the 3-year outcomes. Primary outcomes were the 3-year rates of major amputation, reintervention, and mortality. They also recorded 30-day major adverse limb events (MALE) defined as major amputation or reintervention. Of the 7108 patients with CLTI 79% were non-Hispanic White, 15% were Black, 1% were Asian, and 6% were Hispanic. Compared with White patients, Black patients had higher rates of 3-year major amputation (Black vs White, 32% vs 19%), reintervention (Black vs White, 61% vs 57%), and 30-day MALE (Black vs White, 8.1% vs 4.9%) but lower mortality (Black vs White, 38% vs 42%). Hispanic patients also experienced higher rates of amputation (Hispanic vs White, 27% vs 19%), reintervention (Hispanic vs White, 70% vs 57%), and MALE (Hispanic vs White, 8.7% vs 4.9%). However, mortality was similar between Hispanic vs White groups. A higher presence of comorbidities in Black and Hispanic patients with CLTI is considered the greatest contributing factors to higher amputation and reintervention rates.

Predictors and outcomes of arrhythmia on stage I palliation of single ventricle patients.
This study investigated associated risks for arrhythmias in pediatric patients with single ventricle disease undergoing stage I palliation (S1P). The NPC-QIC (National Pediatric Cardiology Quality Improvement Collaborative) database was used to obtain retrospective patient, surgical, medication, and arrhythmia data. Bivariate analysis of variables associated with arrhythmias and survival was performed at the time of stage II palliation. Of the 2,048 included patients, 36% had arrhythmia noted in their S1P hospitalization, with supraventricular tachycardia (12%) and focal atrial tachycardia (11%) the most common. At discharge, 11% of patients were on an antiarrhythmic medication. Increased risk of arrhythmias were associated with heterotaxy syndrome, younger age at S1P, male sex, and additional anomalies. Increased mortality was associated with female sex, while decreased mortality was associated with antiarrhythmic medication and digoxin use.

Outcomes of in-hospital cardiac arrest among hospitals with and without telemedicine critical care.
This study compared survival rates for inpatients who suffered in-hospital cardiac arrest (IHCA) who had access to Telemedicine Critical Care (TCC) during nights and weekends (off-hours) compared to those who did not. The authors identified 44,585 adults at 280 U.S. hospitals in the Get With The Guidelines® - Resuscitation registry who suffered IHCA in an Intensive Care Unit (ICU) or hospital ward between July 2017 and December 2019. The majority (60.6%) of IHCAs occurred in an ICU, and 32.2% participants suffered IHCA at hospitals with TCC. No difference was found in acute resuscitation survival rates or survival to discharge rates for either IHCA between TCC and non-TCC hospitals. Timing of cardiac arrest did not modify the association between TCC availability and acute resuscitation survival or survival to discharge.

Socioeconomic impact on outcomes during the first year of life of patients with single ventricle heart disease: an analysis of the National Pediatric Cardiology Quality Improvement Collaborative Registry.
In a retrospective cohort analysis of infants enrolled in the National Pediatric Cardiology Improvement Collaborative, researchers investigated the impact of community-level deprivation on morbidity and mortality for infants with single ventricle heart disease in the first year of life. They found that community deprivation was associated with mortality and length of stay for patients with single ventricle congenital heart disease. While patients near the mean deprivation index had a higher hazard of one year mortality compared to those at the extremes of the deprivation index, length of stay and deprivation index were linearly associated, demonstrating the complex nature of socioeconomic factors.

Frequency, characteristics, and outcomes of endovascular thrombectomy in patients with stroke beyond 6 hours of onset in US clinical practice.
In 2018, 2 randomized controlled trials showed the benefit of endovascular thrombectomy (EVT) in acute ischemic stroke patients treated 6 to 24 hours from last known well using imaging-guided selection. However, little is known about outcomes in contemporary nontrial settings. In this study, the investigators assessed the frequency of EVT and outcomes beyond 6 hours in the US Get With The Guidelines-Stroke clinical registry.

Predictors and outcomes of heart block during surgical stage I palliation of patients with a single ventricle: a report from the NPC-QIC.
This study investigated patient and surgical risks of heart block and its effect on 12-month transplant-free survival in children with a single ventricle. In total, 1423 patients were identified from the National Pediatric Cardiology Improvement Collaborative with and without heart block. One-year outcomes were analyzed. A very small percentage (2%) developed heart block during their surgical admission. Associated risk factors for block included heterotaxy syndrome and atrial flutter/fibrillation. Patients with complete heart block had lower 12-month survival, which wasn’t true for patients with second degree block. At 12 months of age, 43% of patients with heart block died and were more likely to experience mortality than patients without heart block.

The impact of team familiarity on intra and postoperative cardiac surgical outcomes.
The authors hypothesized that familiarity among cardiac surgery team members may be an important contributor to better outcomes and thus serve as a target for enhancing outcomes. They found that high team familiarity was associated with reduced cardiopulmonary bypass duration for medium-risk and high-risk patients. Increasing team familiarity was not significantly associated with the odds of major morbidity and mortality. They concluded that team familiarity, which was predictive of improved intraoperative efficiency without compromising major postoperative outcomes, may serve as a novel quality improvement target in the setting of cardiac surgery.

Transradial access for high-risk percutaneous coronary intervention: implications of the risk-treatment paradox.
The study’s objective was to examine whether the association between transradial percutaneous coronary intervention (PCI; TRI) use versus transfemoral PCI (TFI) and in-hospital outcomes is influenced by baseline risk. TRI was found to reduce adverse outcomes when compared with TFI. The authors analyzed 28,005 PCIs performed in a 7-hospital system between July 2009 and April 2018. TRI use increased over time. However a risk-treatment paradox for TRI use was observed not only for bleeding risk, but for acute kidney injury (AKI) and death. The absolute risk difference between TRI and TFI increased with increasing baseline risk.

Coronary revascularization outcomes in relation to skilled nursing facility use following hospital discharge.
Observational analyses comparing coronary artery bypass surgery (CABG) and percutaneous coronary intervention (PCI) among elderly or frail patients are likely biased by treatment selection. PCI is typically chosen for frail patients, while CABG is more common for patients with good recovery potential. In this study. The investigators hypothesized that skilled nursing facility (SNF) use after revascularization was a measure of relative frailty associated with outcomes following coronary revascularization.

Improving smoking and blood pressure outcomes: the interplay between operational changes and local context.
This study identified conditions and operational changes linked to improvements in smoking and blood pressure (BP) outcomes in primary care using samples and interviews from a subset of 104 practices participating in EvidenceNOW, a multisite cardiovascular disease prevention initiative. The authors calculated Clinical Quality Measure improvements, with targets of 10-point or greater absolute improvements in the proportion of patients with smoking screening, and if relevant, counseling and the proportion of hypertensive patients with adequately controlled BP. Primary care staff were surveyed and interviewed. In clinician-owned practices, implementing a workflow to routinely screen and counsel patients on smoking cessation resources, or implementing a documentation change or a referral to a resource alone led to an improvement of at least 10 points in the smoking outcome. These improvements did not occur though in health- or hospital system-owned practices or in Federally Qualified Health Centers. BP outcome improved by at least 10 points among solo practices after medical assistants learned how to take an accurate BP. Among larger, clinician-owned practices, BP outcomes improvement took place when staff took a second BP measurement after the first measurement was elevated and when staff learned where to document this information in the electronic health record. For larger and health- and hospital system-owned practices, 50 or more hours of facilitation was needed to improve BP outcomes.
