The impact of race and its related social determinants of health on cardiovascular disease outcomes has been well documented. However, limited data exist regarding the association of race with in-hospital outcomes in patients admitted for sinus node dysfunction (SND).To evaluate whether racial disparities exist in outcomes for patients hospitalized with a primary diagnosis of SND.The National Inpatient Sample was queried from 2011 to 2018 for relevant ICD-9 and ICD-10 diagnosis and procedure codes. Baseline characteristics and in-hospital outcomes in patients with a primary diagnosis of SND were compared among White and non-White patients. A multivariate logistic regression model was used to adjust for potential confounding factors and statistically significant comorbidities between both cohorts.We identified 655,139 persons admitted with a primary diagnosis of SND, 520,926 (79.5%) of whom were White. Non-White patients had significantly higher all-cause mortality, length of stay, and total hospital cost. There were lower odds of pacemaker insertion (adjusted odds ratio [aOR] 1.13 [95% confidence interval (CI) 1.11-1.15]), temporary transvenous pacing (aOR 1.15 [95% CI 1.11-1.22]), and cardioversion (aOR 1.50 [95% CI 1.42-1.58]) in non-White patients. A subgroup analysis was performed and non-Hispanic Black race was predictive of a decreased odds of pacemaker insertion, cardioversion/defibrillation, and temporary transvenous pacing.Significant differences of in-hospital outcomes exist between White and non-White patients with SND. These findings appeared to be primarily driven by disparities in non-Hispanic Black patients. Increased recognition and focused efforts to mitigate these disparities will improve the care of underrepresented populations treated for SND.

OBJECTIVE: To synthesize the evidence for incidence, pathophysiology, etiology, and protocol-based management of hyperammonemia in lung transplant patients. BACKGROUND: Elevated ammonia levels are toxic to the brain, and hyperammonemia results in a potentially fatal complication for lung transplant recipients. The hallmark of this condition is ammonia production being way out of proportion to the degree of liver derangement. While there are many hypotheses, the cause remains obscure. METHODS: A retrospective review of patients with hyperammonemia following lung transplantation was done to understand the pathophysiology, various treatment modalities, and its impact on patient mortality and morbidity. Studies in the English literature were identified through an electronic database search from PubMed/MEDLINE, Ovid Embase, Google Scholar, Cochrane Database of Systematic Reviews (CDSR), Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Web of Science, and ClinicalTrials.gov until June 2020. No restriction of dates were used, and the search was up until June 2020. DISCUSSION: Mortality among patients with hyperammonemia following lung transplantation is high. Multi-modal treatment approaches include avoiding nephrotoxic drugs, use of bowel decontamination, nitrogen scavengers, branched-chain amino acids, adjustment of immunosuppression, antibiotics like fluoroquinolones or azithromycin, and renal replacement therapy. However, there remains a scarcity of preoperative screening protocol for patients at risk of hyperammonemia as well evidence-based post-operative management guidelines. Intermittent hemodialysis, compared to continuous venovenous hemodialysis, provides better patient outcomes. CONCLUSION: Early detection of patients at risk by appropriate screening, along with maintaining a high degree of suspicion for hyperammonemia and multi-modal treatment approach, is the key to successful patient outcomes. Further prospective observational studies would facilitate development of protocol-based treatment of this potentially fatal condition.

Radiotherapy (RT) is a treatment modality that uses high-energy rays or radioactive agents to generate ionizing radiation against rapidly dividing cells. The main objective of using radiation in cancer therapy is to impair or halt the division of the tumor cells. Over the past few decades, advancements in technology, the introduction of newer methods of RT, and a better understanding of the pathophysiology of cancers have enabled physicians to deliver doses of radiation that match the exact dimensions of the tumor for greater efficacy, with minimal exposure of the surrounding tissues. However, RT has numerous complications, the most common being radiation proctitis (RP). It is characterized by damage to the rectal epithelium by secondary ionizing radiation. Based on the onset of signs and symptoms, post-radiotherapy RP can be classified as acute or chronic, each with varying levels of severity and complication rates. The treatment options available for RP are limited, with most of the data on treatment available from case reports or small studies. Here, we describe the types of RT used in modern-day medicine and radiation-mediated tissue injury. We have primarily focused on the classification, epidemiology, pathogenesis, clinical features, treatment strategies, complications, and prognosis of RP.

Abstract: Temporary mechanical circulatory support (MCS) encompasses a wide array of invasive devices, which provide short-term hemodynamic support for multiple clinical indications. Although initially developed for the management of cardiogenic shock, indications for MCS have expanded to include prophylactic insertion prior to high-risk percutaneous coronary intervention, treatment of acute circulatory failure following cardiac surgery, and bridging of end-stage heart failure patients to more definitive therapies, such as left ventricular assist devices and cardiac transplantation. A wide variety of devices are available to provide left ventricular, right ventricular, or biventricular support. The choice of a temporary MCS device requires consideration of the clinical scenario, patient characteristics, institution protocols, and provider familiarity and training. In this review, the most common forms of left, right, and biventricular temporary MCS are discussed, along with their indications, contraindications, complications, cannulations, hemodynamic effects, and available clinical data

BACKGROUND Pacemaker implantation in the U.S. is rising due to an aging population. The aim of this analysis was to identify risk factors associated with increased mortality and complications in hospitalized patients requiring pacemaker implantation. METHODS We performed a retrospective analysis using the National Inpatient Sample database, identifying hospitalized patients who underwent pacemaker implantation using International Classification of Disease, Tenth Revision, Clinical Modification codes. Independent predictors of inpatient mortality were identified using multivariate logistic regression analysis. RESULTS There were 242,980 hospitalizations with pacemaker implantation during 2016 and 2017. The most frequently encountered indications for hospitalizations involving pacemaker insertion included sick sinus syndrome (SSS) (27.60%), complete atrioventricular (AV) block (21.57%), and second-degree AV block (7.83%). Chronic liver disease was associated with the highest adjusted odds of inpatient mortality (aOR = 5.76, 95% CI: 4.46 to 7.44, p

Hyperkalemia is a recognized and potentially life-threatening complication of heart transplantation. In the complex biosystem created by transplantation, recipients are susceptible to multiple mechanisms for hyperkalemia which are discussed in detail in this manuscript. Hyperkalemia in heart transplantation could occur pre-transplant, during the transplant period, or post-transplant. Pre-transplant causes of hyperkalemia include hypothermia, donor heart preservation solutions, conventional cardioplegia, normokalemic cardioplegia, continuous warm reperfusion technique, and ex-vivo heart perfusion. Intra-transplant causes of hyperkalemia include anesthetic medications used during the procedure, heparinization, blood transfusions, and a low output state. Finally, post-transplant causes of hyperkalemia include hemostasis and drug-induced hyperkalemia. Hyperkalemia has been studied in kidney and liver transplant recipients, but there is limited data on the incidence, causes, management, and prevention in heart transplant recipients. Hyperkalemia is associated with an increased risk of hospital mortality and readmission in these patients. This review describes the current literature pertaining to the causes, pathophysiology, and treatment of hyperkalemia in patients undergoing heart transplantation and focuses primarily on post-heart transplantation.

GOALS We aimed to assess outcomes of patients with liver cirrhosis who underwent therapeutic or diagnostic endoscopic retrograde cholangiopancreatography (ERCP) to determine whether these patients had different outcomes relative to patients without cirrhosis. BACKGROUND ERCP is an important procedure for treatment of biliary and pancreatic disease. However, ERCP is relatively technically difficult to perform when compared with procedures such as esophagogastroduodenoscopy or colonoscopy. Little is known about how ERCP use affects patients with liver cirrhosis. STUDY Using patient records from the National Inpatient Sample (NIS) database, we identified adult patients who underwent ERCP between 2009 and 2014 using International Classification of Disease, Ninth Revision coding and stratified data into 2 groups: patients with liver cirrhosis and those without liver cirrhosis. We compared baseline characteristics and multiple outcomes between groups and compared outcomes of diagnostic versus therapeutic ERCP in patients with cirrhosis. A multivariate regression model was used to estimate the association of cirrhosis with ERCP outcomes. RESULTS A total of 1,038,258 hospitalizations of patients who underwent ERCP between 2009 and 2014 were identified, of which 31,294 had cirrhosis and 994,681 did not have cirrhosis. Of the patients with cirrhosis, 21,835 (69.8%) received therapeutic ERCP and 9459 (30.2%) received diagnostic ERCP. Patients with cirrhosis had more ERCP-associated hemorrhages (2.5% vs. 1.2%; P

BACKGROUND Gallstones and cholecystectomy have been proposed as risk factors for non-alcoholic fatty liver disease (NAFLD). The reason for this may be that both gallstones, as well as NAFLD share several risk factors with regards to their development. Currently, there is a lack of sufficient evidence showing an association between these clinical conditions. AIM To determine whether there is a meaningful association between gallstones and cholecystectomy with NAFLD. METHODS We queried the National Inpatient Sample database from the years 2016 and 2017 using International Classification of Diseases, 10th revision, Clinical Modification diagnosis codes to identify hospitalizations with a diagnosis of gallstone disease (GSD) (includes calculus of gallbladder without cholecystitis without obstruction and acquired absence of gallbladder) as well as NAFLD (includes simple fatty liver and non-alcoholic steatohepatitis). Odds ratios (ORs) measuring the association between GSD (includes gallstones and cholecystectomy) and NAFLD were calculated using logistic regression after adjusting for confounding variables. RESULTS Out of 14294784 hospitalizations in 2016-2017, 159259 were found to have NAFLD. The prevalence of NAFLD was 3.3% in patients with GSD and 1% in those without. NAFLD was prevalent in 64.3% of women with GSD as compared to 35.7% of men with GSD. After controlling for various confounders associated with NAFLD and GSD, multivariate-adjusted analysis showed that there was an association between NAFLD with gallstones [OR = 6.32; 95% confidence interval (CI): 6.15-6.48] as well as cholecystectomy (OR = 1.97; 95%CI: 1.93-2.01). The association between NAFLD and gallstones was stronger in men (OR = 6.67; 95%CI: 6.42-6.93) than women (OR = 6.05; 95%CI: 5.83-6.27). The association between NAFLD and cholecystectomy was stronger in women (OR = 2.01; 95%CI: 1.96-2.06) than men (OR = 1.85; 95%CI: 1.79-1.92). P value was less than 0.001 for all comparisons. CONCLUSION NAFLD is more prevalent in women with GSD than men. The association between NAFLD and cholecystectomy/gallstones indicates that they may be risk factors for NAFLD.

Immunotherapy is rapidly evolving secondary to the advent of newer immunotherapeutic agents and increasing approval of the current agents by the United States Food and Drug Administration to treat a wide spectrum of cancers. Immunotherapeutic agents have gained immense popularity due to their tumor-specific action. Immunotherapy is slowly transforming into a separate therapeutic entity, and the fifth pillar of management for cancers alongside surgery, radiotherapy, chemotherapy, and targeted therapy. However, like any therapeutic entity it has its own adverse effects. With the increasing use of immuno-therapeutic agents, it is vital for physicians to acquaint themselves with these adverse effects. The aim of this review is to investigate the common systemic adverse effects and toxicities associated with the use of different classes of immunotherapeutic agents. We provide an overview of potential adverse effects and toxicities associated with different classes of immunotherapeutic agents organized by organ systems, as well as an extensive discussion of the current recommendations for treatment and clinical trial data. As we continue to see increasing usage of these agents in clinical practice, it is vital for physicians to familiarize themselves with these effects.

In patients with infective endocarditis (IE), ST-elevation myocardial infarction (STEMI) is an uncommon phenomenon. Due to limited data, we intend to evaluate the clinical outcomes in hospitalized patients with STEMI with and without underlying IE. Mortality and morbidity are exponentially worse in STEMI with concomitant IE when compared with without IE. Patients with primary diagnosis of STEMI with and without IE were identified by querying the Healthcare Cost and Utilization Project database of the National Inpatient Sample for the years 2013 and 2014 based on International Classification of Diseases, Ninth Revision codes. During 2013 and 2014, a total of 117,386 patients were admitted with the principle diagnosis of STEMI, out of whom 305 had comorbid IE. There was a significantly increased in-hospital mortality (27.5% vs 10.8%), length of stay (LOS) (14 days vs 5 days), acute kidney injury (AKI; 44.9% vs 18.7%), stroke (23.6% vs 3%), aortic valve replacement (9.5% vs 0.3%), mitral valve replacement (0.2%-5.2%), sepsis (50% vs 6%) and acute respiratory failure (36.7% vs 16.7%) in patients with STEMI with IE when compared with patients with STEMI and without comorbid IE. STEMI without IE had a higher number of angiographies (58.7% vs 25.9%) and percutaneous coronary interventions (50.7% vs 14.4%) during the hospital course when compared with STEMI with IE. In conclusions, hospitalized patients with STEMI with a concurrent diagnosis of IE are at higher risk of in-hospital mortality, increased LOS, AKI, stroke, valve replacements, and acute respiratory failure.

Immunotherapy is an extremely important breakthrough and an exciting new modality of treatment for a wide spectrum of cancers. It is focused around developing agents to stimulate or suppress the immune system, in a specific manner, to fight off a wide spectrum of diseases, particularly cancers. Traditional therapies available for the treatment of cancers include surgical intervention, chemotherapy, radiation therapy or a combination of these, which tend to be very non-specific. However, immunotherapy shows a stark difference from conventional therapy, in fact, that it has a high level of specificity for the tumor-specific antigens. The recent success of cancer immunotherapies in clinical trials is slowly revolutionizing the landscape for cancer therapy. The US Food and Drug Administration has approved numerous agents, after clinical trials showed promising results, for the treatment of multiple cancers. The role of immunotherapy in gastrointestinal cancers has also been very promising, particularly in patients with advanced metastatic disease or malignancies refractory to initial treatment. In this review of literature, we detail and discuss the immunotherapy agents approved for the treatment of GI cancers and glance at the future of immunotherapy for patients with these cancers.

The severe acute respiratory syndrome coronavirus 2 (coronavirus disease 2019, COVID-19) pandemic has placed a tremendous burden on healthcare systems globally. Therapeutics for treatment of the virus are extremely inconsistent due to the lack of time evaluating drug efficacy in clinical trials. Currently, there is a deficiency of published literature that comprehensively discusses all therapeutics being considered for the treatment of COVID-19. A review of the literature was performed for articles related to therapeutics and clinical trials in the context of the current COVID-19 pandemic. We used PubMed, Google Scholar, and Clinicaltrials.gov to search for articles relative to the topic of interest. We used the following keywords: “COVID-19”, “therapeutics”, “clinical trials”, “treatment”, “FDA”, “ICU”, “mortality”, and “management”. In addition, searches through the references of retrieved articles was also performed. In this paper, we have elaborated on the therapeutic strategies that have been hypothesized or trialed to-date, the mechanism of action of each therapeutic, the clinical trials finished or in-process that support the use of each therapeutic, and the adverse effects associated with each therapeutic. Currently, there is no treatment that has been proven to provide significant benefit in reducing morbidity and mortality. There are many clinical trials for numerous different therapeutic agents currently underway. By looking back and measuring successful strategies from previous pandemics in addition to carrying out ongoing research, we provide ourselves with the greatest opportunity to find treatments that are beneficial.

Amyloidosis, a heterogenous group of disorders, is characterized by the extracellular deposition of autologous, insoluble, fibrillar misfolded proteins. These extracellular proteins deposit in tissues aggregated in ß-pleated sheets arranged in an antiparallel fashion and cause distortion to the tissue architecture and function. In the current literature, about 60 heterogeneous amyloidogenic proteins have been identified, out of which 27 have been associated with human disease. Classified as a rare disease, amyloidosis is known to have a wide range of possible etiologies and clinical manifestations. The exact incidence and prevalence of the disease is currently unknown. In both systemic and localized amyloidosis, there is infiltration of the abnormal proteins in the layers of the gastrointestinal (GI) tract or the liver parenchyma. The gold standard test for establishing a diagnosis is tissue biopsy followed by Congo Red staining and apple-green birefringence of the Congo Red-stained deposits under polarized light. However, not all patients may have a positive tissue confirmation of the disease. In these cases additional workup and referral to a gastroenterologist may be warranted. Along with symptomatic management, the treatment for GI amyloidosis consists of observation or localized surgical excision in patients with localized disease, and treatment of the underlying pathology in cases of systemic amyloidosis. In this review of the literature, we describe the subtypes of amyloidosis, with a primary focus on the epidemiology, pathogenesis, clinical features, diagnosis and treatment strategies available for GI amyloidosis.

The ongoing outbreak of severe acute respiratory syndrome coronavirus-2 [SARS-CoV-2, or coronavirus disease 2019 (COVID-19)] was declared a pandemic by the World Health Organization on March 11, 2020. Worldwide, more than 65 million people have been infected with this SARS-CoV-2 virus, and over 1.5 million people have died due to the viral illness. Although a tremendous amount of medical progress has been made since its inception, there continues to be ongoing research regarding the pathophysiology, treatments, and vaccines. While a vast majority of those infected develop only mild to moderate symptoms, about 5% of people have severe forms of infection resulting in respiratory failure, myocarditis, septic shock, or multi-organ failure. Despite maximal cardiopulmonary support and invasive mechanical ventilation, mortality remains high. Extracorporeal membrane oxygenation (ECMO) remains a valid treatment option when maximal conventional strategies fail. Utilization of ECMO in the pandemic is challenging from both resource allocation and ethical standpoints. This article reviews the rationale behind its use, current status of utilization, and future considerations for ECMO in critically ill COVID-19 patients.

This study aimed to explore contemporary in-hospital outcomes and trends of transcatheter aortic valve implantation (TAVI) outcomes in patients with baseline right bundle branch block (RBBB) using data collected from a nationwide sample. Using the National Inpatient Sample, we identified patients hospitalized for an index TAVI procedure from 2016 to 2019. Primary outcomes included in-hospital all-cause mortality, complete heart block, and permanent pacemaker (PPM) implantation. A total of 199,895 hospitalizations for TAVI were identified. RBBB was present in 10,495 cases (5.3%). Patients with RBBB were older (median age 81 vs 80 years, p0.001) and less likely to be female (35% vs 47.4%, p0.001). After adjusting for differences in baseline characteristics and elective versus nonelective admission, patients with RBBB had a higher incidence of complete heart block (adjusted odds ratio [aOR] 4.77, confidence interval [CI] 4.55 to 5.01, p0.001) and PPM implantation (aOR 4.15, CI 3.95 to 4.35, p0.001) and no difference in-hospital mortality rate (aOR 0.85, CI 0.69 to 1.05, p = 0.137). Between 2016 and 2019, there was a 3.5% and 2.9% decrease in in-hospital PPM implantation in patients with and without RBBB, respectively. In conclusion, from 2016 to 2019, the rate of in-hospital PPM implantation decreased during index TAVI hospitalization in both patients with and without RBBB. However, in those with baseline RBBB, complete heart block complication rates requiring PPM implantation remain relatively high. Further research and advances are needed to continue to reduce complication rates and the need for PPM implantation.

Acute respiratory distress syndrome (ARDS) is associated with high mortality. Atrial fibrillation (AF) is a common arrhythmia seen in critically ill patients. The impact of AF on the outcomes in patients with ARDS is less understood. In this analysis we attempt to evaluate the association of concurrent AF and various clinical outcomes in patients with ARDS.We conducted a retrospective analysis of adult discharges from the National Inpatient Sample (NIS) between 2004 and 2014. International Classification of Disease codes were used to identify those with ARDS and AF.We found 1,200,737 hospitalizations with ARDS, out of which 238,455 had concomitant diagnosis of AF. Hospitalizations with AF had higher prevalence of comorbidities including chronic pulmonary disease, diabetes mellitus, hypertension, obesity, congestive heart failure and renal failure. On adjusted analysis, AF was associated with increased odds of acute myocardial infarction, cardiogenic shock, pressor use, acute kidney injury, permanent pacemaker implantation, cardiac arrest, mechanical circulatory support use and higher length of stay and inflation-adjusted cost in hospitalizations with ARDS. However, there was no significant difference in adjusted all-cause mortality in ARDS with and without AF (25.42% vs 20.23%, p=0.53).AF is associated with worse clinical outcomes, higher length of stay and cost in ARDS hospitalizations as compared to those without AF.

Marijuana use is on the rise in the United States. By the end of 2019, 33 states have legalized marijuana use and marijuana byproduct use for medical purposes. However, marijuana use does not come without side effects. This manuscript reviews the increasing usage of marijuana and the different forms (natural and synthetic) that patients may use when presenting to clinicians. It also addresses the biochemical and behavioral changes observed with marijuana use, including the location and changes associated with cannabinoid receptors (abbreviated CB1 and CB2). These two topics lead into an extensive review of the side effects of marijuana use. This manuscript discusses gastrointestinal side-effects, such as Cannabinoid Hyperemesis Syndrome, pancreatitis, and hepatotoxicity. It also briefly reviews cardiovascular, neurologic, and pulmonary side effects. This article provides an overview of therapeutic effects of marijuana including the antiemetic effect, its medical utility as an appetite stimulant, and usefulness in cancer patients post-chemotherapy. A thorough social history pertaining to marijuana use is an important consideration for clinicians in patients presenting with a variety of symptoms, including those effecting the gastrointestinal, cardiovascular, pulmonary, or neurologic systems.

Purpose Using National Inpatient Database (NIS), comparison of clinical outcomes for patients primarily admitted for atrial fibrillation/flutter with and without a secondary diagnosis of amyloidosis was done. Inpatient mortality was the primary outcome and hospital length of stay (LOS), mean total hospital charges, odds of undergoing cardiac ablation, pharmacologic cardioversion, having a secondary discharge diagnosis of heart block, cardiogenic shock and cardiac arrest were secondary outcomes. Methods NIS database of 2016, 2017 was used for only adult hospitalizations with atrial fibrillation/flutter as principal diagnosis with and without amyloidosis as secondary diagnosis using ICD-10 codes. Multivariate logistic with linear regression analysis was used to adjust for confounders. Results 932,054 hospitalizations were for adult patients with a principal discharge diagnosis of atrial fibrillation/flutter. 830 (0.09%) of these hospitalizations had amyloidosis. Atrial fibrillation/flutter hospitalizations with co-existing amyloidosis have higher inpatient mortality (4.22% vs 0.88%, AOR: 3.92, 95% CI 1.81–8.51, p = 0.001) and likelihood of having a secondary discharge diagnosis of cardiac arrest (2.40% vs 0.51%, AOR: 4.80, 95% CI 1.89–12.20, p = 0.001) compared to those without amyloidosis. Conclusions Hospitalizations of atrial fibrillation/flutter with co-existing amyloidosis have higher inpatient mortality and odds of having a secondary discharge diagnosis of cardiac arrest compared to those without amyloidosis. However, LOS, total hospital charges, likelihood of undergoing cardiac ablation, pharmacologic cardioversion, having a secondary discharge diagnosis of heart block and cardiogenic shock were similar between both groups.

Introduction Cirrhosis is known to be an important prognostic factor in determining morbidity and mortality in preoperative cardiac risk assessment for cardiac surgery. Data is limited on outcomes in patients with infective endocarditis (IE) and comorbid liver cirrhosis. The objective of our study is to evaluate the clinical outcomes in patients suffering from IE both with and without underlying liver cirrhosis as well as to determine rates of in-hospital mortality and factors that contribute to this outcome. Hypothesis Liver cirrhosis worsens clinical outcomes in patients with IE. Materials and methods Patients with a principal diagnosis of IE with and without liver cirrhosis were identified by querying the Healthcare Cost and Utilization (HCUP) database, specifically the National Inpatient Sample for the years 2013 and 2014 using International Classification of Diseases, Ninth Revision (ICD-9) codes. Results During 2013 and 2014, a total of 17,952 patients were admitted with a diagnosis of IE, out of whom 780 had concurrent liver cirrhosis. There was increased in-hospital mortality [15.6% vs 10.2%, aOR = 1.57 (1.27-1.93)], acute kidney injury [41.4% vs 32.6%, aOR = 1.45 (1.24-1.69)], and hematologic complications [32.1 vs 14.7%, aOR = 2.87 (2.44-3.37)] in patients with IE with liver cirrhosis when compared to patients with IE without liver cirrhosis. Patients having IE without liver cirrhosis underwent an increased number of interventions, i.e. aortic (7.2 vs 3.7%, aOR = 0.51 (0.34-0.76)) and mitral (4.9% vs 3.4%, aOR = 0.39 (0.23-0.69)) valvular replacements as compared to those with liver cirrhosis, which may explain the increased mortality seen in patients with liver cirrhosis. Conclusion Liver cirrhosis is an important prognostic risk factor for in-hospital mortality in patients with IE. The coagulopathic state in addition to increased rates of bleeding complications and renal dysfunction make these patients poor surgical candidates thus contributing to higher mortality. Further research into the individual risk factors contributing to the increased mortality rates in patients with IE and cirrhosis is required.

Objective: To study inpatient outcomes of infective endocarditis (IE) with concurrent heart blocks Introduction: IE complicated with heart blocks can have adverse outcomes and usually requires immediate surgical and cardiac interventions. Data on outcomes and trends in patients with IE with concurrent heart blocks are lacking. Methods: Patients with a principle diagnosis of IE with or without heart blocks were identified by querying the Healthcare Cost and Utilization (HCUP) database, specifically, the National Inpatient Sample for year 2013 and 2014 based on ICD9 codes. Results: During 2013 and 2014, a total of 18,733 patients were admitted with a diagnosis of IE, out of whom 867 had concurrent heart blocks. There was an increased in-hospital mortality (13% vs 10.3%), length of stay (19 vs 14 days), cost of care (282,573 vs 223,559), cardiogenic shock (8.9% vs 3.2%), placement of an ICD/CRT/PPM (30.6% vs 0.9%), acute kidney injury (40.1% vs 32.6%) and hematologic complications (19.3 vs 15.2%) in patients admitted with IE with heart blocks as compared to those with IE but without heart block. Infective endocarditis and concurrent heart block resulted in increased requirement for aortic (25.7 vs 6.1%) and mitral (17.3% vs 4.2%) valvular replacements as compared to IE without heart block. Conclusions: IE with concurrent heart block worsens in-hospital mortality, length and cost of hospital stay. Our analysis clearly demonstrates an increase in the indications for cardiac procedures, specifically aortic and/or mitral valve replacements and ICD/CRT/PPM placement. A close tele monitoring system and prompt interventions may represent a significant mitigation strategy to avoid adverse outcomes observed in this study.
