INTRODUCTION
Acute pulmonary edema is a common and potentially fatal presentation in the emergency department. More than 1 million patients are admitted annually with a diagnosis of pulmonary edema secondary to cardiac causes.1 Pulmonary edema is broadly split into two main categories: cardiogenic and noncardiogenic. Cardiogenic pulmonary edema is characterized by acute dyspnea caused by the accumulation of fluid within the lung's interstitial and/or alveolar spaces, which is the result of acutely elevated cardiac filling pressures.2 Noncardiogenic pulmonary edema is characterized by fluid accumulation within the alveolar space in the absence of elevated pulmonary capillary wedge pressure.2 These patients often present critically ill, and rapid identification and aggressive management is paramount in caring for patients with pulmonary edema. Dyspnea is the most common presentation with a sensitivity of 89% but a low specificity of 51%.3 Workup of pulmonary edema often includes laboratory testing, electrocardiogram (EKG), chest x-ray (CXR), and often bedside ultrasound (US) and echocardiography.4 Pulmonary edema management depends on the etiology but is often focused on preload and afterload reduction. Diuretics, nitrates, and optimizing ventilatory support through non-invasive and invasive strategies are the mainstay of treatment.
EDUCATIONAL OBJECTIVES
At the end of this practice oral boards case, the learner will:1) recognize unstable vital signs (VS) and intervene to stabilize ventilation and oxygenation, 2) demonstrate the ability to obtain a complete medical history including the important characteristics of chest pain, 3) demonstrate an appropriate exam on a patient, 4) order the appropriate evaluation studies for a patient with complaints of dyspnea, 5) interpret the results of diagnostic evaluation and diagnose Non- ST elevation myocardial infarction (NSTEMI) and pulmonary edema, 6) order appropriate management of pulmonary edema and NSTEMI, and 6) demonstrate effective communication with patient and family members.
EDUCATIONAL METHODS
Practice oral boards.
RESEARCH METHODS
Immediate Feedback was solicited from the learners and observers participating in the case both by verbal discussion and completion of a rating for the case following the debriefing. The efficacy of the educational content was assessed by comparing scoring measures across residents based on the training year. Scoring measures of the American College of Graduate Medical Education (ACGME) core competencies were performed using a scale from 1 - 8, 1-4 being unacceptable performance and 5 - 8 being acceptable. Efficacy was assumed based on full completion of the case by the residents who acted as practice oral board candidates, and a debriefing session followed to discuss the key components of the case.
RESULTS
This case was presented to twelve Emergency Medicine Residents, seven PGY 1 and five PGY 2 at a relatively new residency program. The overall average score for the residents was 5.62. The PGY 1 Residents' average on the case was 5.56, and the average for the PGY 2 Residents was slightly better at 5.70. The slight improvement noted by the PGY 2 Residents is likely attributable to more clinical experience; however, both classes did not have any prior exposure to the oral board format until this simulated experience. Six residents completed all critical actions in the case. Of those who missed a critical action, failing to diagnose NSTEMI and consulting cardiology were the most common. All learners found educational value in the case with an overall rating of 4.83 (1-5 Likert scale, 5 being excellent).
DISCUSSION
Acute pulmonary edema and NSTEMI are common diagnoses that will be frequently encountered for most emergency physicians. This case highlights the need for early identification and aggressive management of the patient presenting with respiratory distress. The differential for respiratory distress is large, but most learners were able to quickly identify pulmonary edema based on the exam findings of jugular vein distention (JVD), rales, and lower extremity edema. Most learners quickly escalated to a non-rebreather mask and ultimately to BPAP (bilevel positive airway pressure) without requesting to intubate the patient. There was notable variation in the approach to administering nitrates, but most ordered an intravenous (IV) nitroglycerin (NTG) drip and requested pharmacy assistance in dosing. Diuretics were ordered by all the learners, but some were hesitant to start early because they felt the effect would be delayed. Some of the residents did not identify ischemic changes on the EKG at first glance but did request to review a second time when the troponin result was positive. All residents gave aspirin after noting the positive troponin, but not all were able to make a clear diagnosis of NSTEMI or consult cardiology. Although the case was relatively straightforward, residents enjoyed early diagnosis and aggressive management of the patient with impending respiratory failure. Many residents are asking for an ultrasound early in the workup of this patient presenting in respiratory distress. Although not a critical action in this case, it highlights the emphasis placed on ultrasonography in the current emergency medicine curriculum.

Review
Cardiovascular diseases (CVDs) remain the leading cause of morbidity and mortality worldwide. Recently, accumulating evidence has revealed hepatic mediators, termed as liver-derived secretory factors (LDSFs), play an important role in regulating CVDs such as atherosclerosis, coronary artery disease, thrombosis, myocardial infarction, heart failure, metabolic cardiomyopathy, arterial hypertension, and pulmonary hypertension. LDSFs presented here consisted of microbial metabolite, extracellular vesicles, proteins, and microRNA, they are primarily or exclusively synthesized and released by the liver, and have been shown to exert pleiotropic actions on cardiovascular system. LDSFs mainly target vascular endothelial cell, vascular smooth muscle cells, cardiomyocytes, fibroblasts, macrophages and platelets, and further modulate endothelial nitric oxide synthase/nitric oxide, endothelial function, energy metabolism, inflammation, oxidative stress, and dystrophic calcification. Although some LDSFs are known to be detrimental/beneficial, controversial findings were also reported for many. Therefore, more studies are required to further explore the causal relationships between LDSFs and CVDs and uncover the exact mechanisms, which is expected to extend our understanding of the crosstalk between the liver and cardiovascular system and identify potential therapeutic targets. Furthermore, in the case of patients with liver disease, awareness should be given to the implications of these abnormalities in the cardiovascular system. These studies also underline the importance of early recognition and intervention of liver abnormalities in the practice of cardiovascular care, and a multidisciplinary approach combining hepatologists and cardiologists would be more preferable for such patients.

Pulmonary and systemic congestion as a consequence of heart failure are clinically recognized as alarm signals for clinical outcome and mortality. Although signs and symptoms of congestion are well detectable in patients, monitoring of congestion in small animals with heart failure lacks adequate noninvasive methodology yet. Here, we developed a novel ultrasonography-based scoring system to assess pulmonary and systemic congestion in experimental heart failure, by using lung ultrasound (LUS) and imaging of the inferior vena cava (Cava), termed CavaLUS. CavaLUS was established and tested in a rat model of supracoronary aortic banding and a mouse model of myocardial infarction, providing high sensitivity and specificity while correlating to numerous parameters of cardiac performance and disease severity. CavaLUS, therefore, provides a novel comprehensive tool for experimental heart failure in small animals to noninvasively assess congestion. As thorough, noninvasive assessment of congestion is not available in small animals, we developed and validated an ultrasonography-based research tool to evaluate pulmonary and central venous congestion in experimental heart failure models.

BACKGROUND
Studies had previously identified three cardiogenic shock (CS) phenotypes (cardiac-only, cardiorenal, and cardiometabolic). Therefore, we aimed to understand better the hemodynamic profiles of these phenotypes in acute myocardial infarction-CS (AMI-CS) using pulmonary artery catheter (PAC) data to better understand the AMI-CS heterogeneity.
METHODS
We analyzed the PAC data of 309 patients with AMI-CS. The patients were classified by SCAI shock stage, congestion profile, and phenotype. In addition, 24 h hemodynamic PAC data were obtained.
RESULTS
We identified three AMI-CS phenotypes: cardiac-only (43.7%), cardiorenal (32.0%), and cardiometabolic (24.3%). The cardiometabolic phenotype had the highest mortality rate (70.7%), followed by the cardiorenal (52.5%) and cardiac-only (33.3%) phenotypes, with significant differences ( < 0.001). Right atrial pressure ( = 0.001) and pulmonary capillary wedge pressure ( = 0.01) were higher in the cardiometabolic and cardiorenal phenotypes. Cardiac output, index, power, power index, and cardiac power index normalized by right atrial pressure and left-ventricular stroke work index were lower in the cardiorenal and cardiometabolic than in the cardiac-only phenotypes. We found a hazard ratio (HR) of 2.1 for the cardiorenal and 3.3 for cardiometabolic versus the cardiac-only phenotypes ( < 0.001). Also, multi-organ failure, acute kidney injury, and ventricular tachycardia/fibrillation had a significant HR. Multivariate analysis revealed that CS phenotypes retained significance ( < 0.001) when adjusted for the Society for Cardiovascular Angiography & Interventions score ( = 0.011) and ∆congestion ( = 0.028). These scores independently predicted mortality.
CONCLUSIONS
Accurate patient prognosis and treatment strategies are crucial, and phenotyping in AMI-CS can aid in this effort. PAC profiling can provide valuable prognostic information and help design new trials involving AMI-CS.

PURPOSE
To investigate the incidence of postoperative cerebral infarction after curative lobectomy, its association with the type of lobectomy, and how postoperative new-onset arrhythmia contributes to postoperative cerebral infarction.
METHODS
The subjects of this analysis were 77,060 patients who underwent curative lobectomy for lung cancer between 2016 and 2018 according to the National Clinical Database. Incidences of postoperative cerebral infarction and postoperative new-onset arrhythmia were analyzed. Moreover, mediation analysis was performed to evaluate the causal pathway between postoperative new-onset arrhythmia and postoperative cerebral infarction.
RESULTS
Postoperative cerebral infarction occurred in 110 (0.7%) patients after left upper lobectomy and in 85 (0.7%) patients after left lower lobectomy. Left upper lobectomy and left lower lobectomy were associated with a higher likelihood of postoperative cerebral infarction than right lower lobectomy. Left upper lobectomy was the strongest independent predictor of postoperative new-onset arrhythmia. However, in the mediation analysis, the odds ratio for cerebral infarction did not change after the addition of the factor of postoperative new-onset arrhythmia.
CONCLUSION
Cerebral infarction occurred significantly more often not only after left upper lobectomy, but also after left lower lobectomy. Postoperative new-onset arrhythmia was less likely to be related to cerebral infarction after left upper lobectomy.

PURPOSE
To examine rates of stroke, myocardial infarction (MI), deep vein thrombosis (DVT), pulmonary embolism (PE), and death in patients after retinal vein occlusion (RVO) compared to controls.
DESIGN
Retrospective cohort study.
METHODS
An aggregated electronic health records research network, TriNetX, was used to identify patients with diagnosis of RVO and a control group of patients with cataract. Patients were excluded if they had history of stroke, MI, DVT, or PE within 2 years of diagnosis of RVO or cataract. Propensity score matching was performed to control for baseline demographics and medical comorbidities. Main outcomes included relative risk (RR) of death, stroke, MI, DVT, and PE after RVO compared to those in matched controls.
RESULTS
A total of 45,304 patients were included in each cohort. There was elevated risk of death in the RVO cohort compared to the control cohort at 1 year (RR = 1.30, P < .01), 5 years (RR = 1.22, P < .01), and 10 years (RR = 1.08, P < .01). There was elevated risk of stroke at 1 year (RR = 1.61, P < .01), 5 years (RR = 1.31, P < .01), and 10 years (RR = 1.18, P < .01). There was elevated risk of MI at 1 year (RR = 1.26, P < .01) and 5 years (RR = 1.13, P < .01), but not at 10 years (RR = 1.06, P = .12). There was mildly elevated risk of DVT at 1 year (RR = 1.65, P < .01) but not at 5 years (RR = 0.94, P = .94) or 10 years (RR = 1.05, P = .37). There was no elevated risk of PE at 1 year (RR = 0.98, P = 0.80), 5 years (RR = 0.95, P = .42), or 10 years (RR = 0.85, P =.40).
CONCLUSIONS
There is an increased rate of death, stroke, and MI after RVO compared to those in matched controls. We emphasize the need for long-term systemic evaluation after RVO.

Observational Study
Aneurysmal subarachnoid hemorrhage (aSAH) may lead to cerebral vasospasm, significantly associated with morbidity and mortality. In double-blind, placebo-controlled phase 3 studies, clazosentan reduces cerebral vasospasm-related morbidity and all-cause mortality in patients with aSAH. There are no reports about the clinical efficacy of clazosentan combination therapy with some other drugs. Initially, we explored the efficacy of clazosentan combination therapy with cilostazol, statin, and antiepileptic drugs. Subsequently, we assessed the add-on effect of fasudil to clazosentan combination therapy for aSAH patients. This multicenter, retrospective, observational cohort study included Japanese patients with aSAH between June 2022 and March 2023. The primary outcome was the ordinal score on the modified Rankin Scale (mRS; range, 0-6, with elevated scores indicating greater disability) at discharge. Among the 47 cases (women 74.5%; age 64.4 ± 15.0 years) undergoing clazosentan combination therapy, 29 (61.7%) resulted in favorable outcomes. Overall, vasospasm occurred in 16 cases (34.0%), with four cases (8.5%) developing vasospasm-related delayed cerebral ischemia (DCI). Both hypotension and vasospasm-related DCI were related to unfavorable outcome at discharge. Fasudil were added in 18 (38.3%) cases. Despite adding fasudil to clazosentan combination therapy, the incidence of aSAH-related vasospasm did not decrease. Added-on fasudil to combination therapy related to pulmonary edema, vasospasm, and vasospasm-related DCI, and unfavorable outcomes. Clazosentan combination therapy could potentially result in favorable outcomes for aSAH patients to prevent post-aSAH vasospasm-related DCI. The add-on effect of fasudil to combination therapy did not demonstrate a significant impact in reducing aSAH-related vasospasm or improving outcomes at discharge.

Review
This review explores the intricate relationship between generalized pustular psoriasis (GPP) and various systemic diseases, shedding light on the broader impacts of this severe skin condition beyond its primary dermatological manifestations. GPP is identified as not only a profound contributor to skin pathology but also a significant risk factor for systemic diseases affecting cardiovascular, hepatic, renal, pulmonary, and skeletal systems, as well as associated with an increased incidence of anemia, depression, anxiety, and arthritis. The research highlights the complex interplay of cytokines, particularly IL-17 and IL-36, which are central to the pathophysiology of GPP and implicated in the exacerbation of systemic conditions. Key findings indicate a higher incidence of cardiovascular events in GPP patients compared to those with other severe forms of psoriasis, notably with a stronger correlation between myocardial infarction history and GPP development. Liver disturbances, frequently reversible upon psoriasis remission, suggest a cytokine-mediated link to hepatic health. Renal dysfunction appears elevated in GPP sufferers, with IL-17 and IL-36 potentially driving renal fibrosis. Similarly, interstitial lung disease and osteoporosis in GPP patients underscore the systemic reach of inflammatory processes initiated in the skin. The associations with anemia, depression, anxiety, and arthritis further complicate the clinical management of GPP, requiring a multidisciplinary approach. The study concludes that managing GPP effectively requires a holistic approach that addresses both the cutaneous and systemic dimensions of the disease, advocating for continued research into the mechanisms that connect GPP with broader health implications to refine therapeutic strategies.

Review
Mechanical circulatory support (MCS) includes temporary and durable mechanical devices used for two sets of indications: 1. acute heart failure (HF) secondary sepsis, a myocardial infarction, or pulmonary emboli, and 2. for chronic end-stage HF secondary to worsening cardiomyopathy despite guideline driven medical treatment. This article is to aide cardiac intensive care unit (ICU) nurses in understanding the history of MCS therapy, the care of the MCS patient in the cardiac ICU, the critical and collaborative role of transplant teams with MCS therapy, educational needs for a successful discharge, and implications for education and shared decision-making when placing these devices.

BACKGROUND
Excessive daytime sleepiness (EDS), experienced in 10% to 20% of the population, has been associated with cardiovascular disease and death. However, the condition is heterogeneous and is prevalent in individuals having short and long sleep duration. We sought to clarify the relationship between sleep duration subtypes of EDS with cardiovascular outcomes, accounting for these subtypes.
METHODS AND RESULTS
We defined 3 sleep duration subtypes of excessive daytime sleepiness: normal (6-9 hours), short (<6 hours), and long (>9 hours), and compared these with a nonsleepy, normal-sleep-duration reference group. We analyzed their associations with incident myocardial infarction (MI) and stroke using medical records of 355 901 UK Biobank participants and performed 2-sample Mendelian randomization for each outcome. Compared with healthy sleep, long-sleep EDS was associated with an 83% increased rate of MI (hazard ratio, 1.83 [95% CI, 1.21-2.77]) during 8.2-year median follow-up, adjusting for multiple health and sociodemographic factors. Mendelian randomization analysis provided supporting evidence of a causal role for a genetic long-sleep EDS subtype in MI (inverse-variance weighted β=1.995, =0.001). In contrast, we did not find evidence that other subtypes of EDS were associated with incident MI or any associations with stroke (>0.05).
CONCLUSIONS
Our study suggests the previous evidence linking EDS with increased cardiovascular disease risk may be primarily driven by the effect of its long-sleep subtype on higher risk of MI. Underlying mechanisms remain to be investigated but may involve sleep irregularity and circadian disruption, suggesting a need for novel interventions in this population.
