Ventricular arrhythmias in Kearns-Sayre syndrome: A cohort study using the National Inpatient Sample database 2016-2019.

BACKGROUND: Degeneration of the cardiac conduction system resulting in complete heart block (CHB), ventricular arrhythmias (VA), and sudden cardiac death (SCD) is recognized in patients with Kearns-Sayre syndrome (KSS) and is potentially preventable with permanent pacemaker (PPM) implantation. However, other mechanisms for SCD have been proposed, and the efficacy of implanting a defibrillator instead of PPM remains to be investigated. METHODS: We utilized the National Inpatient Sample (NIS) database 2016-2019 to investigate the risk of VA or dysrhythmic cardiac arrest (dCA) in KSS patients. We compared the outcomes of KSS to myotonic dystrophy (MD), a more common genetic disorder with similar clinical cardiac features and course. RESULTS: We identified 640 admissions for KSS. VA or dCA were lower in admissions for KSS than MD patients (2.3% vs. 4.5%, p = .009). Device implantation differed between study groups. Approximately, 70% of cases with KSS and conduction abnormalities had pacemaker (± defibrillator) on hospital discharge, compared to 35% in MD. Conduction abnormalities were associated with higher rates of VA or dCA in both study groups. None of the admissions for KSS patients who developed VA or dCA had a pacemaker, and all of them had conduction abnormalities. One-third of admissions for MD patients who developed VA or dCA had a device already implanted prior to the event. CONCLUSION: Despite its effectiveness in preventing VA, PPM remains underutilized in patients with KSS or MD who have conduction abnormalities. PPM alone do not fully prevent VA in MD patients; therefore, addition of defibrillator capacity might be necessary.

Clinical characteristics and outcomes of patients admitted to hospitals for posterior reversible encephalopathy syndrome: a retrospective cohort study.

BACKGROUND: Posterior reversible encephalopathy syndrome (PRES) is usually a benign, yet underdiagnosed clinical condition associated with subacute to acute neurological manifestations primarily affecting white matter. PRES is reversible when recognized promptly and treated early by removal of the insulting factor; however, can lead to irreversible and life-threatening complications such as cerebral hemorrhage, cerebellar herniation, and refractory status epilepticus. METHODS: We utilized the National Inpatient Sample database provided by the Healthcare Cost and Utilization Project (HCUP-NIS) 2017 to investigate the demographic variables (age, sex, and race) for patients with PRES, concomitant comorbidities and conditions, inpatient complications, inpatient mortality, length of stay (LOS), and disposition. RESULTS: A total of 635 admissions for patients aged 18 years or older with PRES were identified. The mean age was 57.2 ± 0.6 years old with most encounters for female patients (71.7%, n = 455) and white as the most prevalent race. Half the patients in our study presented with seizures (50.1%, n = 318), sixty-three patients (9.9%) presented with vision loss, and sixty-four patients (10.1%) had speech difficulty. In addition, 45.5% of patients had hypertensive crisis (n = 289). 2.2% of hospitalizations had death as the outcome (n = 14). The mean LOS was 8.2 (±0.3) days, and the mean total charges were $92,503 (±$5758). Inpatient mortality differed between males and females (1.7% vs. 2.4%) and by race (3.6% in black vs. 1.8% in white) but was ultimately determined to be not statistically significant. Most patients who present with vision disturbance have a high risk of intracranial hemorrhage. Furthermore, end-stage renal disease, atrial fibrillation, and malignancy seemed to be linked with a very high risk of mortality. CONCLUSION: PRES, formerly known as reversible posterior leukoencephalopathy, is a neurological disorder with variable presenting symptoms. Although it is generally a reversible condition, some patients suffer significant morbidity and even mortality. To the best of our knowledge, this is the largest retrospective cohort of PRES admissions that raises clinician awareness of clinical characteristics and outcomes of this syndrome.

Psoriasis as risk factor for non-ischemic dilated cardiomyopathy: a population-based cross-sectional study.

BACKGROUND: Psoriasis is a chronic inflammatory skin condition commonly associated with psoriatic arthritis, malignancy, diabetes, inflammatory bowel disease, and cardiovascular disease. Several reports and studies have reported an association between psoriasis and non-ischemic dilated cardiomyopathy (NIDCM). We aim to study the relationship between psoriasis and non-ischemic dilated cardiomyopathy in a large population-based study. METHODS: We utilized the Healthcare Cost and Utilization Project National Inpatient Sample 2017 database, which represents a 20% sample of all payer hospitalizations in the United States. We investigated hospitalizations for patients aged 18 years old or older with diagnoses of any type of psoriasis and non-ischemic dilated cardiomyopathy. Psoriasis, cardiomyopathy, and other comorbidities were identified through their international classification of diseases, 10th revision codes recorded in the discharge record for each hospitalization. RESULTS: Of a total of 6,084,184 all-cause admissions, 0.5% were admissions for patients with psoriasis (n = 32,807). Of the patients with and without psoriasis who had non-ischemic dilated cardiomyopathy, after adjusting for age, sex, race, diabetes mellitus, hypertension, alcohol abuse, cocaine abuse, arrhythmias, and obesity in a multivariate analysis, the presence of psoriasis was not significantly associated with non-ischemic dilated cardiomyopathy. CONCLUSION: Psoriasis is a chronic autoimmune disorder which carries a higher cardiovascular events and more prevalent traditional atherosclerotic risk factors in comparison to the general population. However, association with non-ischemic cardiomyopathy or NIDCM in particular has not been studied sufficiently. Our study, being one of the first larger studies to assess this correlation, indicated no relationship between psoriasis and non-ischemic dilated cardiomyopathy.

Cardiopulmonary resuscitation in television medical dramas: Results of the TVMD2 study.

INTRODUCTION: Television medical dramas (TVMDs) use cardiopulmonary resuscitation (CPR) as a mean of achieving higher viewing rates. TVMDs portrayal of CPR can be used to teach laypersons attempting to perform CPR and to form a shared professional and layperson mental model for CPR decisions. We studied the portrayal of CPR across a wide range of TVMDs to see whether newer series fulfill this promise. MATERIALS AND METHODS: Advanced cardiac life support (ACLS) certified healthcare providers underwent training in the use of a unique instrument based on the AHA (American Heart Association) guidelines to assess TVMD CPR scenarios. Components of the assessment included the adequacy of CPR techniques, gender distribution in CPR scenes, performance quality by different healthcare providers, and CPR outcomes. Thirty-one TVMDs created between 2010 and 2018 underwent review. RESULTS: Among 836 TVMD episodes reviewed, we identified 216 CPR attempts. CPR techniques were mostly portrayed inaccurately. The recommended compressions depth was shown in only 32.0% of the attempts (n = 62). The recommended rate was shown in only 44.3% of the attempts (n = 86). Survival to hospital discharge was portrayed as twice higher in male patients (67.6%, n = 71) than in female patients (32.4%, n = 29) (p < 0.05). Paramedics were portrayed as having better performance than physicians or nurses; compression rates were shown to be within the recommendations in only 42% (n = 73) of the CPR attempts performed by physicians, 44% (n = 8) of those performed by nurses, and 64% (n = 9) of those performed by paramedics. Complete chest recoil after compression was shown in only 34% (n = 58) of the CPR attempts performed by physicians, 38% (n = 7) of those performed by nurses, and 64% (n = 9) of those performed by paramedics. Outcomes were better on the screen than in real life; among the episodes showing outcome (n = 202), the overall rate of survival from CPR was 61.9% (n = 125). CONCLUSION: Portrayal of CPR in TVMDs remains a missed opportunity for improving performance and communication on CPR.

Administration of inhaled noble and other gases after cardiopulmonary resuscitation: A systematic review.

OBJECTIVE: Inhalation of noble and other gases after cardiac arrest (CA) might improve neurological and cardiac outcomes. This article discusses up-to-date information on this novel therapeutic intervention. DATA SOURCES: CENTRAL, MEDLINE, online published abstracts from conference proceedings, clinical trial registry clinicaltrials.gov, and reference lists of relevant papers were systematically searched from January 1960 till March 2019. STUDY SELECTION: Preclinical and clinical studies, irrespective of their types or described outcomes, were included. DATA EXTRACTION: Abstract screening, study selection, and data extraction were performed by two independent authors. Due to the paucity of human trials, risk of bias assessment was not performed DATA SYNTHESIS: After screening 281 interventional studies, we included an overall of 27. Only, xenon, helium, hydrogen, and nitric oxide have been or are being studied on humans. Xenon, nitric oxide, and hydrogen show both neuroprotective and cardiotonic features, while argon and hydrogen sulfide seem neuroprotective, but not cardiotonic. Most gases have elicited neurohistological protection in preclinical studies; however, only hydrogen and hydrogen sulfide appeared to preserve CA1 sector of hippocampus, the most vulnerable area in the brain for hypoxia. CONCLUSION: Inhalation of certain gases after CPR appears promising in mitigating neurological and cardiac damage and may become the next successful neuroprotective and cardiotonic interventions.

Current Trends in Hypertension Identification and Management: Insights from the National Health and Nutrition Examination Survey (NHANES) Following the 2017 ACC/AHA High Blood Pressure Guidelines.

BACKGROUND: Hypertension is a global health issue associated with increased cardiovascular morbidity and mortality. This study aimed to investigate contemporary hypertension identification and management trends following the 2017 American College of Cardiology/American Heart Association guidelines. METHODS AND RESULTS: Data from the National Health and Nutrition Examination Survey conducted from 2017 to 2020 were analyzed. Participants between 20 and 79 years of age were included. Participants were stratified into different treatment groups based on indication and guideline adherence. Descriptive statistics were used to compare medication use, diagnosis rates, and blood pressure control. A total of 265 402 026 people met the inclusion criteria, of which 19.0% (n=50 349 209) were undergoing guideline antihypertensive management. In the guideline antihypertensive management group, a single antihypertensive class was used to treat 45.7% of participants, and 55.2% had uncontrolled blood pressure. Participants not undergoing guideline antihypertensive management qualified for primary prevention in 11.5% (n=24 741 999) of cases and for secondary prevention in 2.4% (n=5 070 044) of cases; of these, 66.3% (n=19 774 007) did not know they may have hypertension and were not on antihypertensive medication. CONCLUSIONS: Adherence to guidelines for antihypertensive management is suboptimal. Over half of patients undergoing guideline treatment had uncontrolled blood pressure. One-third of qualifying participants may not be receiving treatment. Education and medical management were missing for 2 in 3 qualifying participants. Addressing these deficiencies is crucial for improving blood pressure control and reducing cardiovascular event outcomes.

Trends in Atrial Fibrillation and Ablation Therapy During the Coronavirus Disease 2019 Pandemic.

The coronavirus disease 2019 (COVID-19) pandemic affected many aspects of health care and continues to have an impact as waves of COVID-19 cases re-emerge. Many procedures were negatively impacted by the pandemic, and management was primarily focused on limiting exposure to the virus. We present an analysis of the National Inpatient Sample (NIS) to delineate how COVID-19 affected atrial fibrillation (AF) ablation. The NIS was analyzed from 2017-2020 in order to determine the pre- and intra-pandemic impacts on AF ablation procedures. Admissions were identified using the International Classification of Diseases, 10th Revision, Clinical Modification codes with a primary diagnosis of AF (ICD-10 CM code I48.0, I48.1, I48.2, or I48.91). Admissions were also assessed for the use of cardiac ablation therapy. Comorbidity diagnoses were identified using the Elixhauser comorbidity software (Agency for Healthcare Research and Quality, Healthcare Cost and Utilization Project, Rockville, MD, USA); additional ICD-10 codes for diagnoses and procedures used are also provided. The primary outcome of our study was the trend in ablation therapy during AF admissions. Secondary outcomes included health care disparities, inpatient mortality, and length of stay. Ablation therapy was used in 18,885 admissions in 2020, compared to the preceding 3-year average of 20,103 (adjusted Wald test, P = .002). Multivariate logistic regression revealed a greater likelihood of undergoing ablation therapy (odds ratio, 1.24; 95% confidence interval, 1.10-1.40; P < .001) among 2020 admissions compared to 2017 admissions. Inpatient mortality increased in 2020 compared to the preceding average; however, the difference was not significant. The procedural volume of ablation for AF saw a decrease in 2020; however, surprisingly, more patients were likely to undergo ablation during 2020.

Acute Kidney Injury Associated with Severe SARS-CoV-2 Infection: Risk Factors for Morbidity and Mortality and a Potential Benefit of Combined Therapy with Tocilizumab and Corticosteroids.

BACKGROUND: Acute kidney injury (AKI) is a common complication in patients with severe COVID-19. METHODS: We retrospectively reviewed 249 patients admitted to an intensive care unit (ICU) during the first wave of the pandemic to determine risk factors for AKI. Demographics, comorbidities, and clinical and outcome variables were obtained from electronic medical records. RESULTS: Univariate analysis revealed older age, higher admission serum creatinine, elevated Sequential Organ Failure Assessment (SOFA) score, elevated admission D-Dimer, elevated CRP on day 2, mechanical ventilation, vasopressor requirement, and azithromycin usage as significant risk factors for AKI. Multivariate analysis demonstrated that higher admission creatinine (p = 0.0001, OR = 2.41, 95% CI = 1.56-3.70), vasopressor requirement (p = 0.0001, OR = 3.20, 95% CI = 1.69-5.98), elevated admission D-Dimer (p = 0.008, OR = 1.0001, 95% CI = 1.000-1.001), and elevated C-reactive protein (CRP) on day 2 (p = 0.033, OR = 1.0001, 95% CI = 1.004-1.009) were independent risk factors. Conversely, the combined use of Tocilizumab and corticosteroids was independently associated with reduced AKI risk (p = 0.0009, OR = 0.437, 95% CI = 0.23-0.81). CONCLUSION: This study confirms the high rate of AKI and associated mortality among COVID-19 patients admitted to ICUs and suggests a role for inflammation and/or coagulopathy in AKI development. One should consider the possibility that early administration of anti-inflammatory agents, as is now routinely conducted in the management of COVID-19-associated acute respiratory distress syndrome, may improve clinical outcomes in patients with AKI.

Thirty-Day Readmission Rate and Healthcare Economic Effects of Patients With Transcatheter Aortic Valve Replacement and Coexisting Chronic Congestive Heart Failure.

Transcatheter aortic valve replacement (TAVR) procedures have increased since adoption in 2010. Readmission for TAVR patients with underlying chronic congestive heart failure (cCHF) remains challenging. Therefore, we sought to determine the 30-day readmission rate (30-DRr) of patients who undergo TAVR & co-existing cCHF and its impact on mortality & healthcare utilization in the United States. We performed a retrospective study using the national readmission database year 2017 and 2018. The patients studied were discharged with TAVR as a principal diagnosis and underlying cCHF as a secondary diagnosis according to ICD-10 codes. The primary outcome was a 30-day readmission rate and mortality, while secondary outcomes were the most common diagnoses for readmission, and resource utilization. A total of 76,892 index hospitalization for TAVR with coexisting cCHF: mean age was 79.7 years [SD: ± 2], and 54.5% of patients were males. In-hospital mortality rate for index admission was 1.63%. The 30-DRr was 9.5%. Among the group of readmitted patients, in-hospital mortality rate was 3.13%. Readmission mortality showed a statistically significant increase compared to index mortality (3.13% vs 1.63%, adjusted P ≤ 0.001, aOR: 2.1, 95% CI: 1.6-2.9). The total healthcare in-hospital economic spending was $94.4 million, and total patient charge of $412 million. Approximately 1 in 10 patients who underwent TAVR with underlying cCHF had 30-DRr, with subsequent readmissions associated with increased healthcare spending. Readmission mortality showed a statistically significant increase when compared to index mortality. TAVR patients with cCHF are a vulnerable subset requiring additional outpatient care.

Impact of Frailty on Left Ventricular Assist Device Clinical Outcomes.

Frailty is a clinical syndrome prevalent in older adults and carries poor outcomes in patients with heart failure. We investigated the impact of frailty on left ventricular assist device (LVAD) clinical outcomes. The Nationwide Readmission Database was used to retrospectively identify patients with a primary diagnosis of heart failure who underwent LVAD implantation during their hospitalization from 2014 to 2020. Patients were categorized into frail and nonfrail groups using the Hospital Frailty Risk Score. Cox and logistic regression were used to predict the impact of frailty on inpatient mortality, 30-day readmissions, length of stay, and discharge to a skilled nursing facility. LVADs were implanted in 11,465 patients who met the inclusion criteria. There was more LVAD use in patients who were identified as frail (81.6% vs 18.4%, p <0.001). The Cox regression analyses revealed that LVAD insertion was not associated with increased inpatient mortality in frail patients (hazard ratio 1.15, 95% confidence interval 0.81 to 1.65, p = 0.427). Frail patients also did not experience a higher likelihood of readmissions within 30 days (hazard ratio 1.15, 95% confidence interval 0.91 to 1.44, p = 0.239). LVAD implantation did not result in a significant increase in inpatient mortality or readmission rates in frail patients compared with nonfrail patients. These data support continued LVAD use in this high-risk patient population.

Intracardiac leadless versus transvenous permanent pacemaker implantation: Impact on clinical outcomes and healthcare utilization.

BACKGROUND: Transvenous permanent pacemakers are used frequently to treat cardiac rhythm disorders. Recently, intracardiac leadless pacemakers offer potential treatment using an alternative insertion procedure due to their novel design. Literature comparing outcomes between the two devices is scarce. We aim to assess the impact of intracardiac leadless pacemakers on readmissions and hospitalization trends. METHODS: We analyzed the National Readmissions Database from 2016 to 2019, seeking patients admitted for sick sinus syndrome, second-degree-, or third-degree atrioventricular block who received either a transvenous permanent pacemaker or an intracardiac leadless pacemaker. Patients were stratified by device type and assessed for 30-day readmissions, inpatient mortality, and healthcare utilization. Descriptive statistics, Cox proportional hazards, and multivariate regressions were used to compare the groups. RESULTS: Between 2016 and 2019, 21,782 patients met the inclusion criteria. The mean age was 81.07 years, and 45.52 % were female. No statistical difference was noted for 30-day readmissions (HR 1.14, 95 % CI 0.92-1.41, p = 0.225) and inpatient mortality (HR 1.36, 95 % CI 0.71-2.62, p = 0.352) between the transvenous and intracardiac groups. Multivariate linear regression revealed that length of stay was 0.54 (95 % CI 0.26-0.83, p < 0.001) days longer for the intracardiac group. CONCLUSION: Hospitalization outcomes associated with intracardiac leadless pacemakers are comparable to traditional transvenous permanent pacemakers. Patients may benefit from using this new device without incurring additional resource utilization. Further studies are needed to compare long-term outcomes between transvenous and intracardiac pacemakers.

The Utilization of 15-Minute Multidisciplinary Rounds to Reduce Length of Stay in Patients under Observation Status.

With the recent change to value-based care, institutions have struggled with the appropriate management of patients under observation. Observation status can have a huge impact on hospital and patient expenses. Institutions have implemented specialized observation units to provide better care for these patients. Starting in January 2020, coinciding with the initiation of daily multidisciplinary rounds, our study focused on patients aged 18 and older admitted to our hospital under observation status. Efforts were built upon prior initiatives at Jersey Shore University Medical Center (JSUMC) to optimize patient care and length of stay (LOS) reduction. The central intervention revolved around the establishment of daily "Observation Huddles"-succinct rounds led by hospital leaders to harmonize care for patients under observation. The primary aim was to assess the impact of daily multidisciplinary rounds (MDR) on LOS, while our secondary aim involved identifying specific barriers and interventions that contributed to the observed reduction. Our study revealed a 9-h reduction in observation time, resulting in approximately USD 187.50 saved per patient. When accounting for the period spanning 2020 to 2022, potential savings totaled USD 828,187.50 in 2020, USD 1,046,062.50 in 2021, and USD 1,243,562.50 in 2022. MDR for observation patients led to a reduction in LOS from 29 h to 20 h (p < 0.001).

Arrhythmogenic Right Ventricular Cardiomyopathy: The Role of Genetics in Diagnosis, Management, and Screening.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a predominantly autosomal dominant genetic condition in which fibrous and fatty tissue infiltrate and replace healthy myocardial tissue. This uncommon yet debilitating condition can cause ventricular arrhythmias, cardiac failure, and sudden cardiac death. Management focuses primarily on prevention of syndrome sequelae in order to prevent morbidity and mortality. Genetic testing and screening in affected families, although utilized clinically, has not yet been incorporated in guidelines due to lack of larger studies and data. We aim herein to identify causative gene mutations, present advancements in diagnosis and management, and describe the role of genetic screening and counseling in patients with ARVC. With the advancement of genetic testing and therapy, diseases such as ARVC may become more accurately diagnosed and more effectively managed, ultimately significantly reducing morbidity and mortality.

Low versus high dose anticoagulation in patients with Coronavirus 2019 pneumonia at the time of admission to critical care units: A multicenter retrospective cohort study in the Beaumont healthcare system.

PURPOSE: Coagulopathy is common in patients with COVID-19. The ideal approach to anticoagulation remains under debate. There is a significant variability in existing protocols for anticoagulation, and these are mostly based on sporadic reports, small studies, and expert opinion. MATERIALS AND METHODS: This multicenter retrospective cohort study evaluated the association between anticoagulation dose and inpatient mortality among critically ill COVID-19 patients admitted to the intensive care units (ICUs) or step-down units (SDUs) of eight Beaumont Healthcare hospitals in Michigan, USA from March 10th to April 15th, 2020. RESULTS: Included were 578 patients with a median age of 64 years; among whom, 57.8% were males. Most patients (n = 447, 77.3%) received high dose and one in four (n = 131, 22.7%) received low dose anticoagulation. Overall mortality rate was 41.9% (n = 242). After adjusting for potential confounders (age, sex, race, BMI, ferritin level at hospital admission, intubation, comorbidities, mSOFA, and Padua score), administration of high anticoagulation doses at the time of ICU/SDU admission was associated with decreased inpatient mortality (OR 0.564, 95% CI 0.333-0.953, p = 0.032) compared to low dose. CONCLUSION: Treatment with high dose anticoagulation at the time of ICU/SDU admission was associated with decreased adjusted mortality among critically ill adult patients with COVID-19.

Coronary Sinus Thrombosis in a Patient Without History of Endothelial Cardiac Injury.

Coronary sinus thrombosis (CST) is a rare but life-threatening condition that involves clot formation within the vessel responsible for draining all of the venous blood from the myocardium itself. The coronary sinus is situated in the right atrium approximately half-way between the tricuspid value and the inferior vena cava. The coronary sinus is rarely cited in medical literature due to limited knowledge as well as rarity in clinical encounters. CST can be a rapidly progressive life-threatening emergency as the interruption of vascular drainage can result in pericardial effusions, tamponade and cardiogenic shock. A major clinical challenge in diagnosing and treating this condition is due to relative rarity as well as the non-specificity of presenting symptoms that are often associated with more commonly encountered cardiopulmonary diseases. CST is most commonly induced by endothelial damage, such as post intracardiac instrumentation with catheter guidewires, or any of the criteria outlined by Virchow's triad. Our team described the finding of a thrombus 1.8 cm in diameter in a patient with underlying hepatobiliary cancer as well as underlying bacteremia from infected ascitic fluid. Though our patient remained hemodynamically stable without cardiopulmonary complications, we hope to spark a discussion within the medical community to increase awareness as well as to highlight the need for more research on this potentially life-threatening condition.

Predictability of Inpatient Mortality of Different Comorbidities in Both Types of Acute Decompensated Heart Failure: Analysis of National Inpatient Sample.

BACKGROUND: Several prediction models have been proposed to assess the short outcomes and in-hospital mortality among patients with heart failure (HF). Several variables were used in common among those models. We sought to focus on other, yet important risk factors that can predict outcomes. We also sought to stratify patients based on ejection fraction, matching both groups with different risk factors. METHODS: We conducted a retrospective cohort study utilizing the Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS) 2016 database. RESULTS: There were totally 116,189 admissions for acute decompensated heart failure (ADHF). Of these, 50.9% were for heart failure with reduced ejection fraction (HFrEF) group (n = 59,195), and 49.1% were for heart failure with preserved ejection faction (HFpEF) group (n = 56,994). Overall, in-hospital mortality was 2.5% of admissions for ADHF (n = 2,869). When stratified by HF types, admissions for HFrEF had higher mortality rate (2.7%, n = 1,594) in comparison to admissions for HFpEF (2.2%, n = 1,275) (P < 0.001). Significantly associated variables in univariate analyses were age, race, hypertension, diabetes mellitus, chronic kidney disease (CKD), atrial fibrillation/flutter, obesity, and chronic ischemic heart disease (IHD), while gender and chronic obstructive pulmonary disease (COPD) did not achieve statistical significance (P > 0.1). CONCLUSIONS: To our knowledge, this is the first study to stratify HF patients based on ejection fraction and utilizing different predictors and in-hospital mortality. These and other data support the need for future research to utilize these predictors to create more accurate models in the future.

Anticoagulants Used in Cardiac Catheterization of Patients With Chronic Lymphocytic Leukemia: A Case Report and Overview.

Percutaneous coronary intervention (PCI) is one of the most frequently performed invasive therapeutic procedures and plays a key role in the long-term survival of patients with ischemic heart disease. Over 965,000 angioplasties are performed annually in the United States alone. While the technique and equipment have undergone significant revisions and improvement, the medical community will still benefit from more data and guidance on the optimal selection of mandatory peri-operation anticoagulation in specific, high-risk populations. Many of these procedures are performed on high-risk individuals who have an inherently higher risk of hemorrhage or thrombosis. Unfractionated heparin is the most popular choice in the general population, however, its use carries certain limitations. Here we will describe the use of an uncommonly used anticoagulant in a patient being actively treated for leukemia. We will also discuss the unique properties and benefits of the four most frequently used anticoagulants during a cardiac angioplasty. Our team describes the successful use of bivalirudin during an urgent PCI in a 71-year-old female with eight previous stents that was followed by an uncomplicated recovery period. Our experience contributes to a small, but growing, body of evidence that bivalirudin may be a safe choice to use in lieu of unfractionated heparin in patients with underlying oncological disease. Our patient had several comorbidities that significantly increased their risk of bleeding. We will also review the clinical trials that compared the four most commonly used anticoagulants during cardiac catheterization.

Nonischemic Dilated Cardiomyopathy in Untreated Long-Term Psoriatic Arthritis: A Newly Recognized Association: A Case Report with Mini Review.

BACKGROUND Psoriasis is a chronic inflammatory skin disease associated with multiple comorbidities including psoriatic arthritis (PsA), atherosclerotic disease, metabolic syndrome, diabetes, hypertension, obesity, and depression. Interestingly, nonischemic cardiomyopathy, especially dilated cardiomyopathy (DCM), has been associated with psoriasis and reported in only in a few cases in the literature. CASE REPORT We report the rare case of a 58-year-old man with a medical history of untreated severe psoriasis and PsA who presented with a sudden onset of shortness of breath. Laboratory and radiographic studies showed an elevated level of B-type natriuretic peptide and acute bilateral pulmonary edema. The patient had normal coronary arteries on cardiac catheterization and echocardiography showed newly diagnosed DCM with systolic and diastolic dysfunction. Cardiac magnetic resonance imaging was consistent with nonischemic DCM (NIDCM) with no evidence of hypertrophy, infiltrative process, or edema. The patient was diagnosed with acute congestive heart failure secondary to NIDCM in the setting of long-standing untreated psoriasis. He responded well to diuretics, was placed on guideline-directed medical therapy, and was discharged with a LifeVest personal cardiac defibrillator. As an outpatient, the patient was started on secukinumab, a monoclonal antibody against interleukin-17A. At his last follow-up appointment, the patient reported improvement in his cardiac symptoms and resolution of his psoriatic skin lesions; repeat echocardiography showed improvement in his ejection fraction. CONCLUSIONS Although studies have shown a higher prevalence of cardiovascular disease in patients with psoriasis, an association with NIDCM has not been studied sufficiently. We recommend further studies of the prevalence, pathogenesis, screening, and management of NIDCM in patients with psoriasis.

COVID-19 Associated Spontaneous Pneumothorax and Pneumopericardium: A Case Report.

Novel coronavirus 2019 (COVID-19) has been one of the largest and most devastating global pandemics of our time. There have been several complications of this disease that have also proven to be debilitating and deadly. While primarily affecting the respiratory system, some cases presented with uncommon complications such as pneumopericardium and spontaneous pneumothorax. We present a case of an elderly female diagnosed with COVID-19 found to have both spontaneous pneumothorax and pneumopericardium. She had a complicated hospital course and ultimately succumbed to her illness. While the pathogenesis of these conditions is not yet fully understood, further studies are needed to help clinicians develop treatment and prevention strategies to improve patient outcomes.
