BACKGROUND: Given the heterogeneity of predisposing factors associated with pulmonary infarction (PI) and the lack of clinically relevant outcomes among patients with acute pulmonary embolism (PE) complicated by PI, further investigation is required. METHODS: Retrospective study of patients with central PE in an 11-year period. Data were stratified according to the diagnosis of PI. Multivariable logistic regression analysis was used to analyze factors associated with PI development and determine if PI was associated with severe hypoxemic respiratory failure and mechanical ventilation use. RESULTS: Of 645 patients with central PE, 24% (n = 156) had PI. After adjusting for demographics, comorbidities, and clinical features on admission, only age (OR 0.98, CI 0.96-0.99; p = 0.008) was independently associated with PI. Regarding outcomes, 35% (n = 55) had severe hypoxemic respiratory failure, and 19% (n = 29) required mechanical ventilation. After adjusting for demographics, PE severity, and right ventricular dysfunction, PI was independently associated with severe hypoxemic respiratory failure (OR 1.78; CI 1.18-2.69, p = 0.005) and mechanical ventilation (OR 1.92; CI 1.14-3.22, p = 0.013). CONCLUSIONS: Aging is a protective factor against PI. In acute central PE, subjects with PI had higher odds of developing severe hypoxemic respiratory failure and requiring mechanical ventilation.

BACKGROUND: In prior studies, central pulmonary embolism (PE) was associated with high clot burden and was considered an independent predictor for thrombolysis. Further information about predictors of adverse outcomes in these patients is needed for better risk stratification. The objective is to describe independent predictors of adverse clinical outcomes in patients with central PE. METHODS: Large retrospective, observational, and single-center study of hospitalized patients with central PE. Data were gathered on demographics, comorbidities, clinical features on admission, imaging, treatments, and outcomes. Multivariable standard and Least Absolute Shrinkage and Selection Operator (LASSO) machine learning logistic regressions and sensitivity analyses were used to analyze factors associated with a composite of adverse clinical outcomes, including vasopressor use, mechanical ventilation, and inpatient mortality. RESULTS: A total of 654 patients had central PE. The mean age was 63.1 years, 59% were women, and 82% were African American. The composite adverse outcome was observed in 18% (n = 115) of patients. Serum creatinine elevation (odds ratio [OR] = 1.37, 95% CI = 1.20-1.57; p = 0.0001), white blood cell (WBC) count elevation (OR = 1.10, 95% CI = 1.05-1.15; p < 0.001), higher simplified pulmonary embolism severity index (sPESI) score (OR = 1.47, 95% CI = 1.18-1.84; p = 0.001), serum troponin elevation (OR = 1.26, 95% CI 1.02-1.56; p = 0.03), and respiratory rate increase (OR = 1.03, 95% CI = 1.0-1.05; p = 0.02) were independent predictors of adverse clinical outcomes. CONCLUSION: Among patients with central PE, higher sPESI score, WBC count elevation, serum creatinine elevation, serum troponin elevation, and respiratory rate increase were independent predictors of adverse clinical outcomes. Right ventricular dysfunction on imaging and saddle PE location did not predict adverse outcomes.

INTRODUCTION: Right heart thrombus (RHT), also known as clot in transit, is an uncommon finding in pulmonary embolism (PE) that is associated with increased inpatient mortality. To date, there is no consensus on the management of RHT. Therefore, we aim to describe the clinical features, treatments, and outcomes of patients with simultaneous RHT and PE. METHODS: This is a retrospective, cross-sectional, and single-center study of hospitalized patients with central PE who had RHT visualized on transthoracic echocardiography (TTE) from January 2012 to May 2022. We use descriptive statistics to describe their clinical features, treatments, and outcomes, including mechanical ventilation, major bleeding, inpatient mortality, length of hospital stay, and recurrent PE on follow-up. RESULTS: Of 433 patients with central PE who underwent TTE, nine patients (2%) had RHT. The median age was 63 years (range 29-87), most were African American (6/9), and females (5/9). All patients had evidence of RV dysfunction and received therapeutic anticoagulation. Eight patients received RHT-directed interventions, including systemic thrombolysis (2/9), catheter-directed suction embolectomy (4/9), and surgical embolectomy (2/9). Regarding outcomes, 4/9 patients were hemodynamically unstable, 8/9 were hypoxemic, and 2/9 were mechanically ventilated. The median length of hospital stay was six days (range 1-16). One patient died during hospital admission, and two patients had recurrent PE. CONCLUSION: We described the different therapeutic approaches and outcomes of patients with RHT treated in our institution. Our study adds valuable information to the literature, as there is no consensus on the treatment of RHT. HIGHLIGHTS: Right heart thrombus (RHT) was a rare finding in central pulmonary embolism. Most patients with RHT had evidence of RV dysfunction and pulmonary hypertension. Most patients received RHT-directed therapies in addition to therapeutic anticoagulation.

Rationale: Few case series have described the simultaneous development of angioedema in patients with coronavirus 19 disease (COVID-19). Most of these reports were described in at-risk patients for developing bradykinin angioedema. Therefore, we aim to describe 5 African American patients who developed simultaneous COVID-19 and angioedema. Methods: This was a case series of hospitalized patients with simultaneous angioedema and COVID-19 infection in a single center from May 2020 to February 2022. We used descriptive statistics. The study was approved by the institutional review board. Results: Their median age was 55 years (range 28-66); all patients were African American, and 3/5 were males. All patients developed angioedema within a week of hospitalization. Two subjects had prior history of ACEI-related angioedema but were not exposed to ACEI recently, whereas 1 subject was on chronic lisinopril therapy for the last 3 years. All patients had orofacial involvement; the most common locations were lips (5/5) and tongue (3/5). None had histaminergic features of angioedema (either skin rash or peripheral eosinophilia). 4/5 subjects had respiratory symptoms and chest imaging features of COVID-19 pneumonia, whereas 3/5 subjects developed severe COVID-19 infection. Most patients were treated with standard combination of H1 and H2 blockers, and corticosteroids. A total of 2/5 subjects were intubated; one patient developed refractory tongue swelling, received tracheostomy for extubation, and died due to COVID-19 pneumonia. The median length of angioedema improvement was 44 hours (range 20-168 hours). The median length of hospital stay was 15 days (range 1-49). Conclusion: We described 5 cases of angioedema in COVID-19 patients that shared risk factors and features of bradykinin-related angioedema.
RESUMO
BACKGROUND: Given the heterogeneity of etiologies, pathophysiology, and presentation of angioedema, variations in clinical outcomes, such as intubation and hospital readmissions, need further clarification. OBJECTIVE: To determine the factors associated with intubation and hospital readmissions in patients with angioedema. METHODS: Retrospective study of patients evaluated with a diagnosis of angioedema in a 6-year period. Demographic and clinical data, such as medication use, family history, comorbidities, and symptoms, were recorded. Multivariable logistic regression was used to analyze factors associated with intubation, whereas Cox regression was used to analyze readmissions. RESULTS: Of 636 patients, the most common cause of angioedema was that induced by angiotensin-converting enzyme inhibitor (ACEI) at 58%. The overall mortality was 0.5%. After adjusting for sex, race, comorbidities, and type of angioedema, smoking (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.10-2.93; P = .02), calcium channel blocker therapy (OR, 1.91; 95% CI, 1.18-3.10; P = .009), histaminergic symptoms (OR, 3.21; 95% CI, 1.93-5.33; P < .001), and age (OR, 1.02; 95% CI, 1.00-1.04; P = .02) were independently associated with increased odds of intubation. Involvement of either the pharynx, larynx, or tongue was associated with higher odds of intubation (OR, 20.96; 95% CI, 10.63-41.33; P < .001). A total of 10% of the patients had a readmission for angioedema within 90 days, and 75% occurred within 30 days. After multivariable Cox regression analysis, only chronic obstructive pulmonary disease and asthma (OR, 2.13; 95% CI, 1.12-4.07; P = .02) and ACEI-related angioedema (OR, 2.93; 95% CI, 1.33-6.47; P = .008) were significantly associated with readmissions. CONCLUSION: Smoking, calcium channel blocker use, histaminergic symptoms, age, and upper airway involvement were markedly associated with intubation. The presence of chronic obstructive pulmonary disease, asthma and ACEI-related angioedema were independently associated with increased odds of readmission.
