Snoring Survivors: the impact of obstructive sleep apnoea and continuous positive airway pressure use on in-hospital mortality, length of stay and costs among patients hospitalised with acute cardiovascular disease - A retrospective analysis of 2016-2019 National Inpatient Sample Data.

BACKGROUND: The routine administration of supplemental oxygen to non-hypoxic patients with acute myocardial infarction (AMI) has been abandoned for lack of mortality benefit. However, the benefits of continuous positive airway pressure (CPAP) use in patients hospitalised with acute cardiovascular disease and concomitant obstructive sleep apnoea (OSA) remain to be elucidated. METHODS: In this retrospective case-control analysis, using 10th International Classification of Diseases, Clinical Modification (ICD-10) codes, we searched the 2016-2019 Nationwide Inpatient Sample for patients diagnosed with unstable angina (UA), AMI, acute decompensated heart failure (ADHF) and atrial fibrillation with rapid ventricular response (AFRVR), who also carried a diagnosis of OSA. We identified in-hospital CPAP use with ICD-10-Procedure Coding System codes. In-hospital death, length of stay (LOS) and hospital charges were compared between patients with and without OSA, and between OSA patients with and without CPAP use. RESULTS: Our sample included 2 959 991 patients, of which 1.5% were diagnosed with UA, 30.3% with AMI, 37.5% with ADHF and 45.8% with AFRVR. OSA was present in 12.3%. Patients with OSA were more likely to be younger, male, smokers, obese and have chronic obstructive pulmonary disease, renal failure and heart failure (p<0.001 for all). Patients with OSA had significantly lower in-hospital mortality (aOR 0.71, 95% CI (0.7 to 0.73)). Among patients with OSA, CPAP use significantly increased the odds of in-hospital death (aOR 1.51, 95% CI (1.44 to 1.60)), LOS (adjusted mean difference of 1.49 days, 95% CI (1.43 to 1.55)) and hospital charges (adjusted mean difference of US$1168, 95% CI (273 to 2062)). CONCLUSION: Our study showed that patients with recognised OSA hospitalised for AMI, ADHF and AFRVR had significantly lower mortality regardless of CPAP use, while CPAP treatment among these patients was associated with significantly higher in-hospital mortality and resource utilisation. The routine use of CPAP during acute cardiovascular encounters could neutralise the impact of chronic intermittent ischaemic preconditioning.

Diversity in U.S. Cardiovascular Trainees and Leadership Where we are and What the Future Holds.

Cardiovascular (CV) outcomes can be improved with commonality between provider and patient regarding gender and race/ethnicity. Slow growth in CV care provider diversity is an obstacle for women and underrepresented groups. The hope for more equitable outcomes is unlikely to be realized unless trends change in selection of CV fellows and program directors (PDs). We investigate longitudinal trends of gender and racial/ethnic composition of CV FITs. De-identified demographic data were compiled in a descriptive cross-sectional study from AAMC of internal medicine (IM) residents and CV FITs from 2011 through 2021 to evaluate gender and race/ethnicity trends among CV trainees. Trends of CV fellows who later became program directors were analyzed. In the US between 2011 and 2021, 53% of IM residents were male while 40% female (7% unreported). Among CV FITs, 78% were male and 21% female. Races/ethnicities among CV FITs consisted of 36% non-Hispanic white, 28% non-Hispanic Asian, 5% Hispanic, 4%Black, and 25% were classified within other race/ethnicity categories. The proportion who became CV program directors followed similarly: 79% of PDs were male and 21% female. Demographic profiles for CV FITs have not significantly changed over the past decade despite increased diversity among IM residents. Efforts to improve diversity of CV FITs and PDs need to be analyzed. Slow growth of diversity in CV FITs is outpaced by rising patient diversity, leading to disparities in care and poorer CV outcomes for women and underrepresented minorities. Recruiting, training, and retaining diverse CV FITs is necessary.

Efficacy of Manual Hemostasis for Percutaneous Axillary Artery Intra-Aortic Balloon Pump Removal.

BACKGROUND: The prevalence of peripheral vascular disease has led to the re-emergence of percutaneous axillary vascular access as a suitable alternative access site to femoral artery. We sought to investigate the efficacy and safety of manual hemostasis in the axillary artery. METHODS: Data were collected from a prospective internal registry of patients who had a Maquet® (Rastatt, Germany) Mega 50 cc intra-aortic balloon pumps (IABP) placed in the axillary artery position. They were anticoagulated with weight-based intravenous heparin to maintain an activated partial thromboplastin time (aPTT) of 50-80 seconds. Anticoagulation was discontinued 2 hours prior to the device explantation. Manual compression was used to achieve the hemostasis of the axillary artery. Vascular and bleeding complications attributable to manual hemostasis were classified based on the Valve Academic Research Consortium-2 (VARC-2) and Bleeding Academic Research Consortium-2 (BARC-2) classifications, respectively. RESULTS: 29 of 46 patients (63%) achieved axillary artery homeostasis via manual compression. The median duration of IABP implantation was 12 days (range 1-54 days). Median compression time was 20 minutes (range 5-60 minutes). There were no major vascular or bleeding complications as defined by the VARC-2 and BARC-2 criteria, respectively. CONCLUSION: Manual compression of the axillary artery appears to be an effective and safe method for achieving hemostasis. Large prospective randomized control trials may be needed to corroborate these findings.

Adverse Events After Left Atrial Appendage Closure: Lessons Learned From the Manufacturer and User Facility Device Experience (MAUDE) Database.

Left atrial appendage (LAA) closure devices are alternative treatments recently approved for patients with atrial fibrillation. Due to the novelty of these devices, limited postapproval surveillance data on LAA closure devices have been published. Thus, we analyzed the United States Food and Drug Administration Manufacturer and User Facility Device Experience (MAUDE) database to report these findings. The primary endpoint was final event outcome, and secondary endpoints included management strategies of reported events.

Coronavirus disease 19 in minority populations of Newark, New Jersey.

BACKGROUND: The purpose of this study is to report the clinical features and outcomes of Black/African American (AA) and Latino Hispanic patients with Coronavirus disease 2019 (COVID-19) hospitalized in an inter-city hospital in the state of New Jersey. METHODS: This is a retrospective cohort study of AA and Latino Hispanic patients with COVID-19 admitted to a 665-bed quaternary care, teaching hospital located in Newark, New Jersey. The study included patients who had completed hospitalization between March 10, 2020, and April 10, 2020. We reviewed demographics, socioeconomic variables and incidence of in-hospital mortality and morbidity. Logistic regression was used to identify predictor of in-hospital death. RESULTS: Out of 416 patients, 251 (60%) had completed hospitalization as of April 10, 2020. The incidence of In-hospital mortality was 38.6% (n = 97). Most common symptoms at initial presentation were dyspnea 39% (n = 162) followed by cough 38%(n = 156) and fever 34% (n = 143). Patients were in the highest quartile for population's density, number of housing units and disproportionately fell into the lowest median income quartile for the state of New Jersey. The incidence of septic shock, acute kidney injury (AKI) requiring hemodialysis and admission to an intensive care unit (ICU) was 24% (n = 59), 21% (n = 52), 33% (n = 82) respectively. Independent predictors of in-hospital mortality were older age, lower serum Hemoglobin < 10 mg/dl, elevated serum Ferritin and Creatinine phosphokinase levels > 1200 U/L and > 1000 U/L. CONCLUSIONS: Findings from an inter-city hospital's experience with COVID-19 among underserved minority populations showed that, more than one of every three patients were at risk for in-hospital death or morbidity. Older age and elevated inflammatory markers at presentation were associated with in-hospital death.

Atypical Presentation of Small Lymphocytic Lymphoma with Pericardial Effusion.

BACKGROUND Small lymphocytic lymphoma (SLL) is a low-grade B-cell non-Hodgkin lymphoma and is the solid tumor equivalent of chronic lymphocytic leukemia (CLL) that is found in the peripheral blood. SLL typically presents with lymphadenopathy and is rarely associated with cardiac involvement. This report is of a case of lymphomatous pericardial effusion in a 61-year-old woman who presented with dyspnea. CASE REPORT A 61-year-old woman presented to the emergency department with a three-month history of worsening shortness of breath on exertion. Her symptoms progressed to shortness of breath at rest, with night sweats and chills. She had no weight loss. She was found to have a pericardial effusion, and an urgent pericardiocentesis was performed to prevent cardiac tamponade. Analysis of the pericardial fluid was consistent with a diagnosis of SLL. A bone marrow biopsy and a biopsy of a renal mass were consistent with a diagnosis of SLL. She was treated with rituximab and bendamustine with granulocyte-colony stimulating factor (G-CSF) support and was discharged home. CONCLUSIONS A case is presented of a rare association between SLL and pericardial effusion with a favorable outcome following urgent pericardiocentesis to prevent cardiac tamponade followed by chemotherapy.

Left Ventricular Function Recovery After Transapical TAVR in Patients With Previous Coronary Artery Bypass Graft Surgery.

OBJECTIVE: The transapical (TA) approach is an alternative access technique for transcatheter aortic valve replacement (TAVR) in patients with symptomatic aortic valve stenosis. The impact of prior coronary artery bypass graft (CABG) surgery and how it affects left ventricular function recovery is not well defined. METHODS: Patients who had TAVR at a single center between June 2012 and December 2016 were reviewed. High-risk patients who underwent the procedure via a TA approach were divided into 2 groups based on their history of CABG surgery. Postoperative outcomes were compared between groups. CABG/TA-TAVR patients were subdivided into 2 per baseline left ventricular ejection fraction (LVEF) <50%. The changes in LVEF and valve function at follow-up (1 to 12 months) were analyzed using paired t-tests. RESULTS: Of 923 cases in total, 183 (19.8%) were performed via a TA approach. The mean ± SD Society of Thoracic Surgeons risk score of TA patients was 10.2 ± 4.6. Forty-nine (27%) had a surgical history of CABG. Overall all-cause mortality rates at 30 days, 1 year, and 2 years were similar for both groups (P = 0.59, P = 0.64, P = 0.78). Subgrouping of CABG-TAVR patients (n = 49) identified 24 patients (49%) with LVEF ≥50% vs. 25 (51%) with LVEF <50%. At 1-year follow-up, significant improvements in LVEF (low LVEF group) and valve function for both groups were observed. LVEF ≥50% group (LVEF: ∆: -3%, P = 0.878; aortic valve area [AVA]: ∆: 1.3 cm2, P < 0.001; mean gradient: ∆: -38 mmHg, P < 0.001); LVEF <50% group (LVEF: ∆: 10%, P = 0.01; AVA: ∆: 1.3 cm2, P < 0.001; MG: ∆: -31 mmHg, P < 0.001). CONCLUSIONS: TA-TAVR can be safely performed with acceptable postoperative outcomes in patients with a history of CABG surgery. In those with reduced EF, significant improvements in LV and valve functions are seen at 1-year follow-up.

A Case of Systemic Lupus Erythematosus Presenting as Autoimmune Myelofibrosis.

BACKGROUND Systemic lupus erythematosus (SLE) is characterized by multiorgan involvement and presence of autoantibodies. SLE has a broad range of presentations and manifestations, and as such, its course and organ involvement are unpredictable. The disease results from the interaction of genes, environment, and random effects combining to lead to a loss of tolerance to self-antigens and active autoimmunity. Autoimmune myelofibrosis is a type of non-malignant bone marrow fibrosis that occurs in the presence of systemic autoimmune disease. Cytopenias such as anemia, leukopenia, and thrombocyotopenia are common manifestations of SLE; however, myelofibrosis is a less common and far less recognized complication of SLE. CASE REPORT We report a case of a young African American female who presented with severe anemia and leukopenia, subsequently diagnosed with myelofibrosis and then eventually SLE. The identification of myelofibrosis in SLE is critical as it can be a devastating condition when untreated. Fortunately, autoimmune myelofibrosis in SLE is reversible with treatment of the underlying condition. CONCLUSIONS Autoimmune myelofibrosis is a rare complication of SLE. Autoimmune myelofibrosis could be the first and only presenting feature of SLE. It is sensible to recognize this relationship, as prompt diagnosis and treatment is crucial. Corticosteroids have been shown to be useful in treating both SLE and the associated autoimmune myelofibrosis.

A Rare Culprit of Infective Endocarditis in an IV Drug User: Burkholderia cepacia.

Infective endocarditis (IE) is an infection of the cardiac native or prosthetic valves typically caused by Staphylococcus aureus, viridans streptococci group, and coagulase-negative staphylococci. Risk factors include congenital heart disease, structural and valvular heart disease, implantation of prosthetic heart valves, and intravenous (IV) drug abuse. IE caused by organisms such as Burkholderia cepacia is rarely seen. We herein present a case of a patient with a history of IV drug abuse previously treated for Staphylococcus aureus IE with newly diagnosed IE secondary to B. cepacia. He was taken to the operating room for mitral valve replacement after an echocardiogram revealed severe mitral regurgitation. He was successfully treated with antibiotics. After 2 months, at follow-up, the patient remained free from mechanical valve-related events, had no new occurrences of fever, and had no other symptoms of infection. He reported good exercise tolerance.

Effect of Transcatheter Aortic Valve Implantation on Renal Function in Patients With Previous Renal Dysfunction.

The study aims to investigate the incidence of immediate renal function improvement in renal dysfunction patients who had transcatheter aortic valve implantation (TAVI). TAVI patients with ≥ moderate reduced renal function [estimated GFR ≤ 60 ml/min/1.73 m2] at baseline were identified from a prospectively maintained database. Patients were divided into 3 groups based on percent change [(discharge eGFR - baseline eGFR/baseline GFR) × 100] in eGFR post-TAVR. Improvement ≥ 10%, no change, Decline ≥ 10%. Multivariable logistic regression was performed to identify factors that predicted improvement/decline in GFR postprocedure. Out of 677 patients, 359 (53%) had eGFR ≤ 60 ml/min/1.73 m2. Of these, 188 (52%) had an improvement in eGFR ≥ 10%, 125 (34%) had no change and 48 (14%) observed decline ≥ 10%. All groups had similar proportions of females and age was comparable in patient groups. Patients in whom a decline in eGFR was observed had significantly higher Society of thoracic Surgeons scores (10.7 vs 8.2 vs 8.2; p = 0.007) and incidence of liver disease (6% vs, 0% vs 2%; p = 0.014) than the no-change or improved groups respectively. On multivariable analysis, independent predictors of decline/improvement in eGFR were being female, low left ventricular ejection fraction and baseline liver dysfunction. In conclusion, over half of patients with compromised renal function who underwent TAVI experience an immediate improvement in kidney function post-TAVI. Being female, baseline liver dysfunction and a low left ventricular ejection fraction is associated with an immediate decline in eGFR.

A Band That Causes Leaky Valves: Severe Mitral Regurgitation due to Left Atrial Fibrous Band-A Case Report and Literature Review.

Left atrial fibrous band is a rare clinical and echocardiographic finding characterized by the presence of a fibrous band attached to the mitral valve. Diagnosis is accomplished with transesophageal echocardiography (TEE), live 3D imaging, or cardiac MRI. Most patients are asymptomatic and incidental findings. However, in rare cases, an atrial fibrous band can produce symptoms such as dyspnea on exertion, fatigue, and lightheadedness secondary to mitral regurgitation (MR) which can lead to heart failure if unattended to. More serious complications such as cardioembolic phenomenon can occur. We herein report a case of a 55-year-old male with hypertension who presented with dyspnea on exertion and chest pain. Transthoracic echocardiography (TTE) showed mitral valve prolapse with moderate to severe mitral regurgitation. TEE showed an atrial fibrous band. Given the patient's poor exercise tolerance, he was taken to surgery for a mitral annuloplasty.

Misdiagnosis: Acute Chest Syndrome That Evolved into Acute Respiratory Distress Syndrome in a Patient without a Documented History of Hemoglobinopathy.

Acute chest syndrome (ACS) is a feared complication of sickle cell disease. Here is a case of a patient who presented with symptoms suggestive of acute chest syndrome yet had a delayed diagnosis presumably due to the lack of documented history of sickle cell disease of the patient, consequently evolving into acute respiratory distress syndrome (ARDS). He was subsequently diagnosed with heterozygous sickle cell SC disease on hemoglobin electrophoresis. After appropriate management with mechanical ventilator, broad-spectrum empiric intravenous antibiotics, exchange transfusion, and intravenous fluid resuscitation, the patient was medically optimized and safely discharged home, with significant improvement noted on successive follow-up visits.

A Rare Culprit of Simultaneous Arteriovenous Thromboembolism: Acute Viral Perimyocarditis.

Simultaneous arteriovenous embolism is extremely rare. Herein, we present a rare case of systemic arteriovenous emboli in a healthy 33-year-old male after an episode of acute viral perimyocarditis. The culprits are postulated to be viral-induced myocardial necrosis and resulting proinflammatory state in the setting of negative malignant, autoimmune, genetics, and chronic infectious conditions. The patient was successfully managed with guideline-directed medical therapy and safely discharged to a subacute rehabilitation facility.

A Rare Culprit of Spontaneous Abortion, Latent Tuberculosis Complicated by Disseminated Peritoneal TB.

This is a case of a 38-year-old female with latent TB complicated by disseminated peritoneal TB with associated spontaneous abortion, who was initially thought to have an ovarian neoplasm, prompting extensive workup. Laparoscopy with biopsy later confirmed the patient's condition; she was initiated on the appropriate therapy and had a full recovery.
