ABSTRACT
PURPOSE: Percutaneous transluminal angioplasty (PTA) remains the mainstay of endovascular therapy for infrapopliteal chronic limb-threatening ischemia (CLTI), but outcomes have not been well characterized using high-quality data. The aim of this meta-analysis was to provide an updated benchmark for rates of primary patency and binary restenosis after PTA using prospectively collected, predominantly core-lab adjudicated randomized controlled trial (RCT) data. MATERIALS AND METHODS: MEDLINE, EMBASE, Cochrane Central, and ClinicalTrials.gov were queried for RCTs published through November 2022 using PTA as a control arm and including patients with infrapopliteal CLTI. Studies were excluded if >25% of patients had intermittent claudication, other vessels were included, or primary patency or binary restenosis were not outcomes. Outcomes were analyzed using random effects models. This analysis was publicly registered (PROSPERO ID#394543). No funding was utilized. RESULTS: Seventeen RCTs were included (1048 patients, 1279 lesions). Pooled primary patency rates using data from 6 RCTs were 68% at 6 months (95% confidence interval [CI]=45%-84%) and 66% at 12 months (95% CI=51%-79%). Pooled binary restenosis rates using data from 11 RCTs were 54% at 6 months (95% CI=33%-73%) and 60% at 9 to 12 months (95% CI=39%-78%). Significant heterogeneity was present in all outcomes (I2>50%, p<0.0001). Publication bias was not observed (Egger's p>0.1). CONCLUSIONS: This meta-analysis provides estimates for binary restenosis and primary patency following PTA utilizing prospectively collected, predominantly core-lab adjudicated data. Results demonstrate 1-year primary patency rates that are 10% to 20% higher than what has been historically used in power calculations. These new estimates will help facilitate more accurate power analysis for future RCTs. CLINICAL IMPACT: Rates of primary patency and binary restenosis after percutaneous transluminal angioplasty (PTA) have not been well-described using high-quality data, and investigators have been utilizing estimates of 40% to 50% and 45% to 65%, respectively, when performing power calculations for trials. This meta-analysis demonstrates using high-quality, prospectively collected, and predominantly core-lab adjudicated randomized controlled trial data that actual rates of primary patency are closer to 60% up to 1 year following PTA and provides the first meta-analysis estimate of binary restenosis rates up to 1 year after PTA. These estimates will help facilitate more accurate power calculations for future RCTs in this space.
ABSTRACT
BACKGROUND: Hispanic and Latino patients are under-represented in existing healthcare disparities research in pulmonary embolism (PE). The goal of this study was to determine if differences in PE severity, treatment modality, or in-hospital outcomes exist for Hispanic or Latino patients with PE. METHODS: All PE cases from 2013 to 2019 at a single institution were reviewed. Clinical characteristics, imaging findings, intervention types, and in-hospital and 30-day outcomes were collected. Two cohorts were created based on patients' self-reported ethnicity. Outcomes were compared using univariate and multivariate analysis. RESULTS: A total of 1265 patients were identified with confirmed PE; 474 (37%) identified as Hispanic or Latino. Hispanic or Latino patients presented with high-risk PE significantly less often (19% vs 25%, p = 0.03). On univariate analysis, Hispanic or Latino patients had lower rates of PE-specific intervention (15% vs 19%, p = 0.03) and similar rates of inpatient mortality (6.8% vs 7.5%, p = 0.64). On ordinal regression analysis, Hispanic or Latino ethnicity was associated with lower PE severity (OR 0.69, 95% CI 0.54-0.89, p = 0.003). In subgroup analyses of intermediate and high-risk PEs, ethnicity was not a significant predictor of receipt of PE-specific intervention or in-hospital mortality. CONCLUSIONS: At this institution, Hispanic or Latino patients were less likely to present with high-risk PE but had similar rates of inpatient mortality. Future research is needed to identify if disparities in in-hospital care are driving perceived differences in PE severity and what addressable systematic factors are driving higher-than-expected in-hospital mortality for Hispanic or Latino patients.

Peripheral arterial disease (PAD) represents one of the most prevalent cardiovascular disease processes and carries a high burden of morbidity and mortality. Patients with chronic limb-threatening ischemia (CLTI), the most severe manifestation of PAD, have the highest rates of cardiovascular morbidity and mortality of the overall PAD population. Patients with below-the-knee (BTK) PAD have an increased propensity toward CLTI due to small-vessel caliber and the frequently comorbid conditions of end-stage renal disease and diabetes mellitus, which tend to affect small artery beds preferentially. For those with BTK PAD with CLTI, the standard of care is revascularization. Early revascularization was performed using surgical bypass. However, endovascular techniques, starting with percutaneous transluminal angioplasty and expanding to the modern armamentarium of adjunctive devices and therapies, have become standard of care for most patients with CLTI due to BTK PAD. In this review, we will discuss the modern surgical and endovascular approaches to revascularization, as well as devices that are currently in development or preapproval study for the treatment of BTK PAD.
ABSTRACT
Acute coronary syndromes (ACS) remain one of the leading causes of cardiovascular morbidity and mortality in the United States and around the world. Because of the acute nature of ACS presentations, timely identification, risk stratification, and intervention are of the utmost importance. Twenty years ago, we published the first iteration of our institutional chest pain clinical pathway in this journal, which separated patients presenting with chest pain into one of the 4 levels of decreasing acuity, with associated actions and interventions for providers based on the level. This chest pain clinical pathway has undergone regular review and updates under a collaborative team of cardiologists, emergency department physicians, cardiac nurse practitioners, and other associated stakeholders in the treatment of patients presenting with chest pain. This review will discuss the key changes that our institutional chest pain algorithm has undergone over the last 2 decades and what the future holds for chest pain algorithms.

BACKGROUND: Venous thromboembolism (VTE) affects >1.2 million Americans annually. Although the clinical outcomes and economic burdens of VTE have been well described, the impact of VTE on patients' health status has yet to be summarized. This systematic review summarizes how patient-reported outcome measures (PROMs) have been used in VTE to date. METHODS AND RESULTS: PubMed/MEDLINE was queried for literature published through March 2023 using PROMs in a population of patients with VTE. Studies were excluded if the reference was an editorial, review, or case report, or if the study included patients with conditions other than VTE. Qualitative analyses were performed. After screening and exclusion, 136 references were identified; 5 described PROM development, 20 focused on PROM validation, and 111 used PROMs in outcomes research. The most used generic PROMs were the 36-item Short-Form Health Survey and EuroQol 5-dimensional questionnaire, and the most common disease-specific PROMs were the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms and the Pulmonary Embolism Quality of Life Questionnaire. PROMs were used to quantify the changes in health status after diagnosis, characterize the trajectory of subsequent improvement, and identify drivers of continued impairments in health status like postthrombotic syndrome and postpulmonary embolism syndrome. PROMs were also used to investigate the impact of novel treatment modalities on quality of life. CONCLUSIONS: This review demonstrates the many benefits of PROM use, including quantifying changes in health status with treatment, capturing patients' experiences with the treatment itself, and identifying complications of VTE. Incorporating PROMs into VTE care will be an essential component of evaluating the effectiveness of novel therapies and should lead to improved shared decision-making for patients with VTE.

Pulmonary embolism (PE) is the third most common cause of cardiovascular death; however, gender disparities in PE remain understudied. All PE cases at a single institution between January 2013 and June 2019 were retrospectively reviewed. The clinical presentation, treatment modalities, and outcomes were compared between men and women using univariate and multivariate analyses adjusting for differences in baseline characteristics. A total of 1,345 patients were diagnosed with acute PE, of whom 56.3% were women (n = 757). Women had a significantly higher mean body mass index (29.4 vs 28.4) and a higher frequency of hypertension (53% vs 46%) and hormone use (6.6% vs 0%; all p <0.02). Men had a higher frequency of smoking (45% vs 33%, p <0.0001). Women had significantly lower PE severity index classifications (p = 0.0009). The rates of intensive care unit admission, vasopressor requirements, extracorporeal membrane oxygenation cannulation, and mechanical ventilation were similar between the genders. There was no significant difference in the treatment modality used between the genders. Although the risk factors and PE severity index class differed between the genders, there was no significant difference in resource utilization or treatment modality. Gender was also not a significant predictor of in-hospital mortality, moderate or severe bleeding, increased length of stay, or readmission in the study population.

Clinical pathways are useful tools for conveying and reinforcing best practices to standardize care and optimize patient outcomes across myriad conditions. The NewYork-Presbyterian Healthcare System has utilized a clinical chest pain pathway for more than 20 years to facilitate the timely recognition and management of patients presenting with chest pain syndromes and acute coronary syndromes. This chest pain pathway is regularly updated by an expanding group of key stakeholders, which has extended from the Columbia University Irving Medical Center to encompass the entire regional healthcare system, which includes 8 hospitals. In this 2023 update of the NewYork-Presbyterian clinical chest pain pathway, we present the key changes to the healthcare system-wide clinical chest pain pathway.

ABSTRACT
Acute cardiac injury is prevalent in critical COVID-19 and associated with increased mortality. Its etiology remains debated, as initially presumed causes - myocarditis and cardiac necrosis - have proved uncommon. To elucidate the pathophysiology of COVID-19-associated cardiac injury, we conducted a prospective study of the first 69 consecutive COVID-19 decedents at CUIMC in New York City. Of 6 acute cardiac histopathologic features, presence of microthrombi was the most commonly detected among our cohort. We tested associations of cardiac microthrombi with biomarkers of inflammation, cardiac injury, and fibrinolysis and with in-hospital antiplatelet therapy, therapeutic anticoagulation, and corticosteroid treatment, while adjusting for multiple clinical factors, including COVID-19 therapies. Higher peak erythrocyte sedimentation rate and C-reactive protein were independently associated with increased odds of microthrombi, supporting an immunothrombotic etiology. Using single-nuclei RNA-sequencing analysis on 3 patients with and 4 patients without cardiac microthrombi, we discovered an enrichment of prothrombotic/antifibrinolytic, extracellular matrix remodeling, and immune-potentiating signaling among cardiac fibroblasts in microthrombi-positive, relative to microthrombi-negative, COVID-19 hearts. Non-COVID-19, nonfailing hearts were used as reference controls. Our study identifies a specific transcriptomic signature in cardiac fibroblasts as a salient feature of microthrombi-positive COVID-19 hearts. Our findings warrant further mechanistic study as cardiac fibroblasts may represent a potential therapeutic target for COVID-19-associated cardiac microthrombi.

Iatrogenic complications may manifest in a variety of ways. We present the case of an 86-year-old woman who underwent a percutaneous coronary intervention with a drug-eluting stent for non-ST-segment elevation myocardial infarction followed by leadless pacemaker placement through a femoral approach. Her post-procedure course was complicated by new onset high-output heart failure secondary to iatrogenic arteriovenous fistula formation, requiring covered stent placement.
