Background: Recent trends of hospitalizations and in‐hospital mortality are not well defined in sarcoidosis. We examined aforementioned trends and prevalence of cardiovascular manifestations and explored rates of implantable cardioverter‐defibrillator implantation in hospitalizations with sarcoidosis. Methods and Results: Using data from the National Inpatient Sample, a retrospective population cohort from 2005 to 2014 was studied. To identify sarcoidosis, an International Classification of Diseases, Ninth Revision, Clinical Modification ( ICD‐9‐CM ) diagnosis code was used. We excluded hospitalizations with myocardial infarction, coronary artery disease, and ischemic cardiomyopathy. Cardiovascular manifestations were defined by the presence of diagnosis codes for conduction disorders, arrhythmias, heart failure, nonischemic cardiomyopathy, and pulmonary hypertension. A total of 609 051 sarcoidosis hospitalizations were identified, with an age of 55±14 years, 67% women, and 50% black. The number of sarcoidosis hospitalizations increased from 2005 through 2014 (138 versus 175 per 100 000, P trend <0.001). We observed declining trends of unadjusted in‐hospital mortality (6.5 to 4.9 per 100 sarcoidosis hospitalizations, P trend <0.001). Overall ≈31% (n=188 438) of sarcoidosis hospitalizations had coexistent cardiovascular manifestations of one or more type. Heart failure (≈16%) and arrhythmias (≈15%) were the most prevalent cardiovascular manifestations. Rates of implantable cardioverter‐defibrillator placement were ≈7.5 per 1000 sarcoidosis hospitalizations ( P trend =0.95) during the study period. Black race was associated with 21% increased risk of in‐hospital mortality (odds ratio, 1.21; 95% confidence interval, 1.16–1.27 [ P <0.001]). Conclusions: Sarcoidosis hospitalizations have increased over the past decade with a myriad of coexistent cardiovascular manifestations. Black race is a significant predictor of in‐hospital mortality, which is declining. Further efforts are needed to improve care in view of low implantable cardioverter‐defibrillator rates in sarcoidosis.

Atrial fibrillation is a common arrhythmia with a lifetime risk of 37% in individuals older than 55 years.1 Atrial fibrillation is also associated with significant cardiovascular morbidity and mortality.2 New-onset atrial fibrillation has been recognized as a common occurrence after noncardiac and cardiac surgery, such as aortic valve replacement (AVR).3-5

Toxic megacolon (TM) is one of the fatal complications of inflammatory bowel disease (IBD) or any infectious etiology of the colon that is characterized by total or partial nonobstructive colonic dilatation and systemic toxicity. It is associated with high morbidity and mortality, and surgical management is necessary for the majority of the cases. An accurate history and physical examination, plain radiographs of the abdomen, sigmoidoscopy, and, most important of all, awareness of the condition facilitate diagnosis in most cases. Operative intervention is warranted when massive hemorrhage, perforation, or peritonitis complicate the clinical scenario or medical therapy fails to control the disease. We sought to review the management challenges of TM and its possible management strategies in this article.

Background: Critical limb ischemia (CLI) morbidity and mortality rates have historically been disproportionately higher than for other atherosclerotic diseases, however, recent trends have not been reported. In patients admitted with CLI, we aimed to examine trends in in-hospital mortality, major amputations, length of stay, and cost of hospitalizations overall and stratified by type of revascularization procedures. Methods: Using 2011 to 2017 National Inpatient Sample data, we identified CLI-related admissions based on International Classification of Diseases, Ninth and Tenth Edition, Clinical Modification codes. Primary outcomes of interest were in-hospital mortality and major amputations. Secondary outcomes were the length of stay and cost of hospitalization. We stratified outcomes based on endovascular or open surgical interventions. We also performed hierarchical multivariable regression analyses of outcomes based on age, sex, race, hospital size, type, and location. Results: We identified 2 643 087 CLI-related admissions between 2011 and 2017. CLI admissions increased from 0.9% to 1.4% P trend <0.0001 as well as overall peripheral artery disease admissions (4.5%–8.9%, P trend <0.0001). In-hospital mortality for the entire CLI cohort decreased from 3.3% to 2.7%, P trend <0.0001, and major amputations decreased from 10.9% to 7%, P trend <0.0001. A decline was also noted for the length of stay from 5.7 (3.1–10.1) to 5.4 (3.0–9.2) days ( P trend <0.0001), whereas admission costs increased from USD $11 791 ($6676–$21 712) to $12 597 ($7248–$22 748; P trend <0.0001). Endovascular interventions increased ( P trend <0.0001) against a decline in surgical interventions ( P trend <0.0001). Black race, female sex, and age ≥60 years were associated with higher in-hospital mortality, whereas Black race, male sex, and age<60 years were associated with higher major amputations. Conclusions: A relatively small decrease in absolute numbers for mortality and major amputations were observed against a backdrop of increasing CLI admissions over recent years. Patients with CLI received more endovascular interventions than surgical interventions over time. However, admissions for endovascular interventions were characterized by higher risk patient profiles and a higher risk of major amputations as compared with surgical interventions.
