Patients hospitalized for acute myocardial infarction (AMI) may have concomitant positive coronavirus disease 2019 (COVID-19). We aimed to compare the risk of in-hospital mortality in patients primarily hospitalized for AMI with or without concomitant COVID-19 positive status. Using the random-effects model, we conducted a systematic review and meta-analysis of published articles from December 1, 2019, to April 1, 2022. There were eight studies with 10,128 patients, including 612 patients with COVID and 9516 patients without COVID. A total of 261 patients (42.64%) with COVID-19 positive and 612 patients (6.43%) with negative COVID-19 status died in the hospital. Pooled data showed that patients with a primary diagnosis of AMI with COVID-19 infection had more than five times increased risk of in-hospital mortality compared to patients without COVID-19 (OR: 5.06, 95% CI: 3.61, 7.09; I

INTRODUCTION We aimed to evaluate the clinical benefits of a de-escalation strategy from prasugrel or ticagrelor to clopidogrel versus continuation of prasugrel or ticagrelor along with aspirin in both strategies for patients presenting with acute coronary syndrome (ACS) and treated with percutaneous coronary intervention (PCI), and to analyze the effect of the recently published randomized clinical trial (RCT) by Park et al., which included the largest sample size ever and the largest switched number of patients, on current guidelines and practices. DATA SOURCES The PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar databases were searched systematically from inception to May 2021 by using the search terms ('de-escalation' OR 'switching') AND ('antiplatelet' OR 'clopidogrel' OR 'ticagrelor' OR 'prasugrel') AND ('percutaneous coronary intervention' OR 'PCI'' OR 'Acute coronary syndrome' OR 'ACS'). STUDY SELECTION AND DATA EXTRACTION We included RCTs that reported the primary outcomes, i.e. net clinical benefits and Bleeding Academic Research Consortium (BARC) type 2 or higher bleeding. A combination of both ischemic and bleeding events was defined as a net clinical benefit. DATA SYNTHESIS A total of four RCTs were included, with 5952 patients. A random-effects meta-analysis revealed that a de-escalation strategy was associated with lower ischemic and bleeding events (net clinical benefits; risk ratio [RR] 0.63, 95% confidence interval [CI] 0.47-0.85; p = 0.003), and lower BARC type 2 or higher bleeding (RR 0.51, 95% CI 0.29-0.91; p = 0.02) when compared with a continuation strategy. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE The current guidelines recommend potent P2Y12 prasugrel or ticagrelor for 12 months despite their association with a high risk of bleeding. Our meta-analysis updates cardiologists, providing them with the best available evidence in managing patients with ACS who underwent PCI. CONCLUSION Among patients with ACS treated with PCI, a de-escalation strategy (prasugrel or ticagrelor to clopidogrel) is associated with lower ischemic and bleeding events (net clinical benefits) and lower BARC type 2 or higher bleeding; however, due to the limited number of included studies, further high-quality studies are needed to establish the clinical efficacy of the de-escalation strategy.

This review aims to evaluate if there are clinical benefits of curcumin (CUR) in patients with polycystic ovary syndrome (PCOS). Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were systematically searched to identify only randomized clinical trials (RCTs) that assessed CUR in patients with PCOS from inception to May 5, 2021. Five RCTs were included with a total of 296 patients, with 148 among the CUR groups and 148 patients among the control group. Revised Cochrane risk-of-bias tool for randomized trials was used to assess the risk of bias, three RCTs provided a low risk of bias and two provided a high risk of bias. Compared with the control group, CUR was associated with a statistically significant improvement in the glycemic control including fasting blood glucose (MD = -3.67; 95% CI = [-5.25, -2.08], p < .00001), insulin level (MD = -1.91; 95% CI = [-2.97, -0.84], p = .0005), homeostasis model assessment of insulin resistance (MD = -0.55; 95% CI = [-0.83, -0.27], p = .0001), and quantitative insulin sensitivity check index (MD = 0.01; 95% CI = [0.00, 0.02], p = .0005). The mean difference in total cholesterol was also statistically significant (MD = -15.55; 95% CI = [-30.33, -0.76], p < .04). The rest of the secondary outcomes, including LDL, HDL, sex hormone, body weight, and CRP, were not statistically significant. This review concluded that among patients with PCOS, the use of CUR demonstrated a significant difference from the control group for glycemic control. Those findings suggest that CUR confers clinical benefits in patients with PCOS. However, due to the limited number of the included studies, further high-quality studies are needed to establish the clinical efficacy of the CUR.

The clinical features of cardiac myxoma vary significantly from asymptomatic to severe cardiovascular complications like atrioventricular valve obstruction and thromboembolism depending on the location, size, and mobility of the tumor. Echocardiography is the diagnostic study of choice, and surgical resection is the method of choice to prevent complications. We report a case of a 47-year-old female who presented with exertional dyspnea, malaise, and weight loss. Physical examination was significant for jugular venous distension, basal crackles in lungs, 2+ pedal edema, and rumbling diastolic murmur at apex. CT of the chest revealed a hypodense filling defect in the left atrium. Transthoracic echocardiogram showed a 5.5 × 4.5 cm mobile density, likely myxoma, attached to the interatrial septum and prolapsing into the left ventricle during the diastolic phase, causing functional mitral stenosis. She underwent a resection of cardiac myxoma. The histopathology report confirmed the diagnosis of myxoma, and post-operative recovery was uneventful.

The immune checkpoint inhibitor (ICIs) as Nivolumab and Ipilimumab is a novel class of medication used in the management of several metastatic malignancies. ICIs can cause immune-related adverse events due to autoreactive T cell activation. Cardiovascular complications comprised myocarditis, conduction abnormalities, ventricular storm, and cardiomyopathy. Cardiomyopathy is one of the significant side effects highlighted in some of the case reports. The physicians should include autoimmune toxicities as the potential differential diagnosis in patients presenting with an unusual presentation and receiving ICIs. We report a case of a 66-year-old female with advanced renal cell carcinoma who developed cardiomyopathy and ventricular tachycardia from nivolumab and ipilimumab therapy.

Near-fatal asthma (NFA) is a life-threatening condition that represents the most severe clinical phenotype of asthma and can progress to fatal asthma. Patients with NFA do not respond adequately to conventional medical therapy and urgent intervention is needed to provide adequate oxygenation by invasive mechanical ventilation. While mechanical ventilation is a potentially life-saving intervention, it could cause lung injury, barotrauma, and dynamic hyperinflation due to high ventilator settings resulting in hemodynamic instability. Extracorporeal membrane oxygenation (ECMO) provides full respiratory support with adequate gas exchange in patients with NFA and improves survival rate. We present a case of a young female patient who presented with NFA, and her clinical condition was worsening despite invasive positive pressure mechanical ventilation.

Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) is an uncommon adulthood disorder that presents as focal swellings and pain accompanied by abnormal changes in bone and surrounding soft tissues. X-rays of the involved region are usually insignificant; however, CT and MRI show excellent visualization of the affected structures. Typical radiological images show cortical thickening leading to decreased marrow cavity, bony erosion, and ligament ossifications. Other associated findings are synovitis and joint effusions. It is usually diagnosed on the basis of clinical as well as radiological findings. The treatment initially relies on non-steroidal anti-inflammatory drugs (NSAIDs). Patients showing poor response are started on corticosteroids and disease-modifying antirheumatic drugs (DMARDs). We report two patients who presented with joint swellings. Their workup unmasked the underlying SAPHO, which was managed well with NSAIDs.

Amyloidosis is a clinical condition characterized by amyloid fibril deposition into different organ systems. The most common types are light chain (AL) amyloidosis and transthyretin amyloidosis (ATTR) amyloidosis. Amyloidosis involves the heart with an incidence of 1.38 to 3.69 per 100,000 person-years and a prevalence of 14.85 per 100,000 person-years between 2004 and 2018. Diagnosis of cardiac amyloidosis can be made through cardiac imaging, including cardiac magnetic resonance imaging (CMR) and 99mTc-labeled pyrophosphate (PYP) cardiac scan. However, a tissue biopsy is frequently needed to confirm the diagnosis. Herein, we report such a case of cardiac amyloidosis. The patient presented with pericardial effusion and acute kidney injury as the initial presentation. The presumptive diagnosis was ATTR amyloidosis, but the endomyocardial biopsy confirmed the diagnosis of AL amyloidosis. The patient was started on bortezomib, cyclophosphamide, and dexamethasone therapy. We aimed to highlight the different diagnostic modalities of cardiac amyloidosis and the importance of obtaining tissue biopsy to confirm the amyloidosis type before starting the treatment.

Deep neck space infection and viral myocarditis related to coronavirus disease 2019 (COVID-19) have both been described in the medical literature. However, there are only three reported cases of retropharyngeal infection as a presenting pathology in the setting of COVID-19. A 26-year-old woman presented to the emergency room with fever and neck swelling and pain 1 month after COVID-19 infection. A computed tomography scan of the neck demonstrated tonsillitis with retropharyngeal infection. She was also found to have heart failure with an ejection fraction (EF) of

Brugada syndrome is an autosomal dominant genetic disorder that primarily affects myocardial sodium channels and has been associated with an increased risk of ventricular tachyarrhythmias and sudden cardiac death. Here, we report a case of a 58-year-old Hispanic male with a history significant for prior pulmonary tuberculosis infection who presented with pleuritic left-sided chest pain associated with body aches, productive cough, fevers, and chills and was found to be positive for SARS-CoV-2 by real-time reverse-transcription-polymerase chain reaction (rRT-PCR). Electrocardiogram (ECG, EKG) on presentation demonstrated a coved ST-segment elevation in V1-V2, suggesting Brugada pattern type 1 without evidence of ischemic changes. EKG changes normalized once fever and hyponatremia improved.

At baseline, solid organ transplant recipients are at an increased risk for infectious complications due to the complex immunosuppressive regimens. The available data in renal transplant patients who contract coronavirus disease 2019 (COVID-19) demonstrates dangerously high mortality rates (33%) in those who require hospitalization and/or ICU level care. Interestingly, the data for transplant patients who do not require hospitalization shows significantly lower mortality (3%) despite being on an immunosuppressive regimen. We present the case of a young male patient with a history of renal transplant who tested positive for COVID-19; he was mildly symptomatic with cough, sinusitis, and headache, was worked up as an outpatient, and treated as an outpatient with bamlanivimab monotherapy with no adjustment to his immunosuppressive regimen. This case aims to highlight the possibility of safely managing mild cases of COVID-19 in solid organ transplant patients receiving immunosuppression as an outpatient with monoclonal antibody (mAb) therapy.

BACKGROUND: Anemia is a common complication in chronic kidney disease (CKD) with increased morbidity and mortality. Recently published RCTs were conducted to compare the effect of the new medication roxadustat (ROX) with erythropoiesis-stimulating agent (ESA) in dialysis-dependent CKD (DD-CKD) patients. Our article aimed to meta-analyze published RCTs to investigate the efficacy and safety of ROX for anemia in DD-CKD patients and update the effect of the new studies on overall analysis with subsequent impact on management. METHODS: Electronic databases (PubMed, EMBASE, Scopus, Web of Science, Cochrane Central, and Google Scholar) were searched systematically from inception to July 2021 by using this search term (Roxadustat OR ASP1517 OR FG4592 OR “FG-4592”) AND (kidney OR renal) AND (Anemia). We only included randomized control trials (RCTs) that reported the primary outcome of change in hemoglobin (Hb) level and iron utilization parameters, including ferritin, serum iron, TSAT, TIBC, transferrin, and hepcidin. RESULTS: Ten RCTs were finally included with 3031 patients in the ROX group and 2737 patients in the control group. ROX was associated with increase in Hb level (SMD: 0.2; 95% CI: 0.02, 0.39; P=0.03), TIBC (SMD: 0.79; 95% CI: 0.61, 0.98; P

Cholesterol embolization syndrome (CES) is a rare presentation of systemic atherosclerosis, which commonly presents in patients with risk factors of coronary artery disease and usually occurs after cardiac or vascular procedures. Laboratory tests are nonspecific, and imaging studies may visualize the plaque. Management includes supportive care directed to relieve the end-organ damage. The prognosis of CES is poor, with high mortality of up to 29% if the CES resulted in atheroembolic renal disease (AERD). In our report, we present a 90-year-old Caucasian female who was diagnosed with CES and complicated with AERD. The patient did not undergo any cardiac or vascular procedures. This case highlights the importance of considering CES and AERD as a potential cause of renal failure, especially in high-risk patients, even if the patients did not have any history of cardiac or vascular intervention.

Diabetic ketoacidosis (DKA) is a significant complication of poorly controlled diabetes. In diabetics, it typically occurs due to insulin deficiency resulting in lipolysis and subsequent ketone body formation and acidosis. The emergence of the COVID-19 infection has been associated with several complications, with the most prominent being pulmonary and cardiovascular-related. However, in some cases, patients with COVID-19 infection present with diabetic ketoacidosis. The pathophysiology of DKA in COVID-19 infection is different and currently not completely understood. The manifestation of DKA in COVID-19 patients is associated with increased severity of mortality and length of stay in these patients. Here, we describe a patient with no past medical history who presented with COVID-19 symptoms and was found to be in DKA. This case report highlights the possible underlying pathophysiology associated with this complication.

Azithromycin is a broad-spectrum antibiotic of the macrolide class and has multiple effects on the cardiovascular system, including prolonged corrected QT (QTc) interval. However, there is limited literature on the association between azithromycin and bradyarrhythmias. Monitoring the patient via telemetry can detect bradycardia. The diagnosis of azithromycin-induced bradycardia is usually made by the exclusion of other causes of bradycardia. We report a case of a 44-year-old female with past medical history of obstructive sleep apnea who presented to our hospital due to polysubstance drug overdose with possible aspiration pneumonia. The patient received azithromycin and subsequently developed symptomatic bradycardia two days post-onset of antibiotic treatment. This case raises awareness amongst physicians about the possibility of azithromycin-induced bradycardia and explains the different mechanisms that can cause it.

Cryptococcus neoformans is an encapsulated, yeast-like fungus that commonly lives in the environment due to soil contamination by the faeces of birds, especially pigeons. Cryptococcus is an opportunistic fungal infection frequently diagnosed in immunocompromised patients with HIV, steroid use, malignancy, history of organ transplantation, or, rarely, sarcoidosis. There have been only a few reports of cryptococcus infection in sarcoidosis patients who were not on steroid treatment. Here, we highlight the importance of considering opportunistic fungal infection in asymptomatic treatment-naive sarcoidosis patients. We present a patient with a history of asymptomatic, treatment-naive sarcoidosis who presented with headache and was diagnosed with cryptococcal meningitis in the presence of an idiopathic T-cell lymphopenia. LEARNING POINTS Cryptococcus is an opportunistic fungal infection commonly diagnosed in immunocompromised patients.Sarcoidosis is a multi-systemic disease characterized by the formation of granulomas in various organs, most commonly found in the lungs and mediastinal lymph nodes.

A meta-analysis of observational studies comparing differences in outcomes between restrictive blood transfusion (RBT) and liberal blood transfusion (LBT) in patients with acute myocardial infarction (AMI) reported that LBT is associated with higher all-cause mortality. Few randomized clinical trials (RCTs) have compared RBT to LBT in patients with AMI and anemia, but no meta-analysis of RCTs was performed to date.To assess the clinical effect of RBT compared to LBT in patients with AMI and anemia regarding was all-cause mortality, recurrent MI, revascularization, and heart failure exacerbation.The electronic databases Ovid MEDLINE, EMBASE, Cochrane Central, Scopus, and Google Scholar, were systematically searched to identify eligible studies published before June 19th, 2021. RCTs that assessed the effect of RBT compared to LBT were included. The primary endpoint was all-cause mortality. Secondary endpoints included recurrent MI, revascularization, and heart failure exacerbation.Three RCTs with 821 patients were included (421 received RBT, and 400 received LBT). The mean age was 75.9 ± 6.1 years, and 56% were male. Our meta-analysis showed that RBT was not associated with reduced all-cause mortality (RR = 1.61; 95% CI = 0.38-6.96, p = 0.52), recurrent MI (RR = 0.98; 95% CI = 0.48-1.96, p = 0.94), revascularization (RR = 1.18; 95% CI = 0.26-5.44, p = 0.83) and heart failure exacerbation (RR = 0.86; 95% CI = 0.23-3.22, p = 0.82) when compared to LBT.RBT was not associated with reduced all-cause mortality, recurrence of MI, need for revascularization, or heart failure exacerbation in patients with AMI and anemia compared to LBT. A larger RCT is required to confirm the above findings.

Brown recluse spider is a spider of the genus Loxosceles and also known as violin spider or fiddle-back spider. Brown recluse spider is characterized by having six eyes, with a pair in front, a pair on both sides, and a gap between the pairs. The other spiders have eight eyes in two rows of four. Brown recluse spider bites are challenging to verify but may be clinically diagnosed with consideration of geographic location, seasonality, and clinical characteristics. We present a case that involves a brown recluse spider bite in a 59-year-old female with malnutrition and polysubstance use who developed systemic symptoms and a dermonecrotic wound. Local wound care and intravenous (IV) antibiotics lead to clinical improvement by hospital day three, at which time the patient left against medical advice. The case highlights the challenges of diagnosing a brown recluse spider bites, particularly in a patient with multiple risk factors for necrotizing soft tissue infection. Furthermore, the present case represents one of the few case reports of a brown recluse spider bite in Michigan.

A 71-year-old male patient with a past medical history of hypertension, hyperlipidemia, and chronic kidney disease stage II presented with a complaint of intermittent palpitations for three months and was found to have wide complex tachycardia on the electrocardiogram (ECG). The patient was given adenosine and amiodarone, following which he underwent synchronized cardioversion at 150 Joules followed by 200 Joules without successful conversion. He was subsequently initiated on lidocaine drip at the rate of 1 to 4 mg/minute to maintain adequate rhythm control, which converted him to sinus rhythm and relieved his symptoms. An eventual assessment with an electrophysiology study identified the presence of incessant left ventricular tachycardia (VT). The mechanism was confirmed to be left posterior fascicular ventricular tachycardia (LPF-VT). Successful mapping and ablation for the LPF-VT were achieved. Post-procedure cardiac MRI showed two small areas of near-transmural delayed enhancement. These areas are associated with nulled areas in the inferolateral wall at the left posterior His-Purkinje fascicle. This case highlights fascicular VT as a separate clinical entity, with its characteristic ECG features and acute MRI features after ablation.

IntroductionThe role of intravenous (IV) iron in chronic heart failure has been well studied, however, its role in acute heart failure (AHF) is less well-known. Including the recent AFFIRM-HF trial, we performed a systematic review and meta-analysis to highlight the role of IV iron in AHF with iron deficiency.HypothesisWe hypothesized that IV iron doesn’t change mortality or heart failure re-hospitalization rates in patients with AHF with iron deficiency.MethodsWe conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) and cohort studies published from inception till June 30, 2021. We searched PubMed, MEDLINE, EMBASE (embase.com), and Cochrane database including only RCTs and Cohort studies. We also included one prospective and one retrospective Cohort studies and two RCTs in our meta-analysis. Eligible studies included adults with AHF, left ventricular ejection fraction less than 40%-50%, and able to receive IV iron therapy. Outcomes included re-hospitalization rates and overall mortality from 30 days to 52 weeks post randomization (in one RCT). We used random-effects model calculating Risk Ratio (RR) with 95% confidence interval (95% CI) using Review Manger 5.4 software. I2statistics was used to assess heterogeneity.ResultsThere were total 1561 participants in both groups (IV iron and placebo/control) of four studies. The controls were comparable in both cohort studies and both the RCTs were well matched. Our results showed re-hospitalization in 278 of 833 (33.37%) patients in the IV iron/exposure group and 337 of 728 (0.46%) patients in the placebo/control group. The pooled result showed that the risk of rehospitalization was comparable across both groups (RR 0.85, 95%CI 0.62-1.17; I2=45%, P=0.14). However, subgroup analysis, including RCTs only showed that IV iron decreases re-hospitalization rate by 28% compared to placebo (RR 0.72, 95% CI: 0.64, 0.82, I2=0%, P2 =0%).ConclusionsIV iron showed significant improvement in re-hospitalization rate for AHF hospitalizations in iron deficient patients but didn’t improve overall mortality. We need larger RCTs to further validate its effect on mortality.

Coronavirus disease 2019 (COVID-19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Clinical manifestations are diverse and can vary from mild respiratory symptoms to severe hypoxic respiratory failure. In severe cases, infection can cause gastrointestinal, renal, cardiac, neurological and haematological complications and result in multi-organ failure. There are very few reports of parapneumonic effusion in patients with COVID-19. We describe two patients with COVID-19 who had loculated empyema and discuss the clinical course and therapeutic options. LEARNING POINTS: The clinical manifestations of COVID-19 vary from mild to severe disease and can result in multi-organ failure. Pleural empyema is usually treated with a combination of antibiotics and surgical drainage of the pleural cavity.

ObjectivesWhile the use of novel oral anticoagulants (NOACs) has been approved in the treatment of non-valvular atrial fibrillation (NVAF), we are lacking studies on individual NOACs in NVAF with valvular heart disease (VHD) including bio-prosthetic valve and valve repair. We aimed to determine the efficacy and safety of rivaroxaban compared to warfarin in prevention of thromboembolism in patients with NVAF with VHD.MethodsWe searched PubMed, MEDLINE, and EMBASE including only RCTs and Cohort studies from inception till April 2021. Eligible studies compared rivaroxaban with warfarin in patients with NVAF with VHD. We excluded patients with valvular AF. We used Review Manager (version 5.4, Cochrane Collaboration, Oxford, UK) applying the Mantel-Haenszel test and followed PRISMA guidelines. Risk ratio (RR) and 95% confidence intervals (CIs) were estimated using a random-effects method and heterogeneity using I squared test.ResultsWe had total of 23136 participants in both groups. Our results showed stroke and systemic thromboembolism in 88 of 4258 (2.06%) patients in the rivaroxaban group compared to 351 of 18878 (1.85%) patients in the warfarin group (RR 0.76; 95% CI, 0.55, 1.06; heterogeneity I2 = 35%, P = 0.10), major bleeding in 247 of 4258 (5.8%) patients in the rivaroxaban group compared to 270 of 18879 (1.4%) patients in the warfarin group (HR 1.68; 95% CI, 0.59, 4.77; heterogeneity I2 = 97%) and intracranial hemorrhage in 24 out of 2583 (0.9%) patients in the rivaroxaban group compared to 35 of 2160 (1.6%) in warfarin group (HR 0.49; 95% CI, 0.16, 1.56; heterogeneity I2 = 70%).ConclusionsOur results show that rivaroxaban is comparable to warfarin in prevention of stroke and systemic thromboembolism in patients with NVAF with VHD. Rivaroxaban is also comparable to warfarin in bleeding risks in these patients.REGISTRATION NUMBERCRD42021222490

BackgroundNovel Corona Virus Disease 2019 (COVID-19) has resulted in more than three and half million deaths worldwide as of June 6, 2021. The role of aspirin in prevention of COVID-19 mortality has not been much studied. We aimed to study the relationship between aspirin use and covid-19 mortality.MethodsWe searched PubMed, MEDLINE, EMBASE, and Cochrane database for studies from January 2019 till June 6, 2021 with inclusion criteria of RCT, Cohort study, studies reporting mortality, and comparison studies on aspirin versus non-aspirin. Statistical analysis was done with Review Manager 5.4 statistical software using the inverse variance method. We assessed the pooled hazard ratio (HR), and 95% confidence interval using the random effect model and I-squared test was used to determine statistical heterogeneity.ResultsWe included five retrospective cohort studies which met our inclusion criteria with total of 14065 participants in both groups. There were 6797 participants in the aspirin group and 7268 participants in the non-aspirin group. Our results show that the use of aspirin was associated with 53% decrease in mortality compared to non-aspirin in patients with COVID-19 (adjusted HR 0.47, 95% CI 0.35-0.63, P< 0.001, I2= 47%). In the analysis restricted to patients hospitalized for COVID-19, the use of aspirin was associated with a 49% reduction in the risk for in-hospital mortality (adjusted HR 0.51, 95% CI 0.33-0.80, P = 0.004, I2= 39%).ConclusionsOur results show that aspirin is associated with decrease in both overall mortality and in-hospital mortality in patients with COVID-19.

Non-bacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis, is a rare form of noninfectious endocarditis presenting with thromboembolism including ischemic cerebral stroke. It is mostly associated with advanced malignancy and characterized by the presence of sterile vegetation on heart valves. The diagnosis is usually based on vegetations seen on an echocardiogram, with negative blood cultures suggesting a noninfectious etiology. The treatment for this condition includes systemic anticoagulation. In this report, we discuss the case of a 61-year-old Caucasian female who presented to our facility with an ischemic stroke. She was found to have vegetations on the mitral valve with negative blood cultures. Further studies revealed metastatic pancreatic cancer. The patient's condition improved following in-hospital management, and she was discharged home for outpatient follow-up and treatment. Through this report, we highlight the importance of considering a search for malignancy in patients presenting with these clinical features. Early diagnosis and prompt management are critical to reduce the complications of NBTE and improve the patients' quality of life.

Background There are no clear consensus guidelines on the indications and types of anticoagulation therapies in patients with bio-prosthetic valves either with concomitant atrial fibrillation (AF) or sinus rhythm. In our meta-analysis, we assessed the safety and efficacy of DOACs as compared to the standard treatment with warfarin in patients with AF and bioprosthetic valves. Methods We included randomized controlled trials (RCTs), cohort studies in the English language, and studies reporting patients with valvular heart disease that included bioprosthetic valvular disease. A systematic literature review using Embase, PubMed, and Web of Science was performed using the terms “Direct Acting Oral Anticoagulant,” “Oral Anticoagulants,” “Non-Vitamin K Antagonist Oral Anticoagulant,” “Atrial Fibrillation,” “Bioprosthetic Valve” for literature published prior to January 2021. Extraction of data from included studies was carried out independently by three reviewers from Covidence. We assessed the methodical rigor of the included studies using the modified Downs and Black checklist. Results Four RCTs and one observational study (n=1776) were included in our study. A random-effect model using RevMan (version 5.4; The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen) was used for data analysis. The pooled data showed that there was a non-significant reduction in the incidence of stroke and systemic embolism in the patients taking DOACs as compared to warfarin (HR 0.69; 95% CI, 0.29, 1.67; I2 = 50%). The incidence of major bleeding was lower in the DOACs group; the difference was statistically significant (HR 0.42; 95% CI, 0.26, 0.67; I2 = 7%). The difference was not statistically significant for all-cause mortality in both groups (HR 1.24; 95% CI, 0.91, 1.67; I2 = 0%). Conclusion Our results showed that there was no difference in the outcomes of stroke and systemic embolism between DOACs and warfarin but there were statistically significantly lower major bleeding events. We conclude that larger clinical trials are needed to assess the true safety and efficacy of DOACs in patients with AF and bioprosthetic valves.

Acute myocarditis is commonly caused by viral infections resulting from viruses such as adenovirus, enteroviruses, and, rarely, coronavirus. It presents with nonspecific symptoms like chest pain, dyspnea, palpitation, or arrhythmias and can progress to dilated cardiomyopathy or heart failure. Fulminant myocarditis is a potentially life-threatening form of the condition and presents as acute, severe heart failure with cardiogenic shock. In this report, we discuss a case of a 41-year-old female who presented with cough and chest pain of two days' duration. The patient had a new-onset atrial flutter. Her chest auscultation revealed bilateral crackles. Laboratory workup revealed elevated troponin levels, and the patient tested positive for coronavirus disease 2019 (COVID-19) by nasopharyngeal swab polymerase chain reaction (PCR). Transthoracic echocardiogram revealed a low left ventricular (LV) ejection fraction of 35-40% compared to 55% one year prior, as well as a granular appearance of LV myocardium. The patient's condition subsequently improved clinically and she was discharged home. Due to cardiac involvement and characteristic myocardial appearance on the echocardiogram, cardiac magnetic resonance (CMR) imaging was performed for further evaluation about two months from the date of admission. CMR showed extensive myocardial inflammation with a typical pattern of sub-epicardial and mid-wall delayed enhancement, confirming the diagnosis of myocarditis. This case highlights myocarditis as a potential complication of COVID-19 that requires early diagnosis and proper management to improve patients' quality of life. Additionally, we highlight the features of myocarditis on CMR in the acute phase and two months after clinical recovery.

Primary light chain amyloidosis (AL amyloidosis) rarely presents as sick sinus syndrome (SSS), and only a few cases have been reported in the literature. A higher index of suspicion is needed to diagnose AL amyloidosis in patients presenting with SSS. Recognizing the electrocardiography (ECG) and transthoracic echocardiogram (TTE) findings for amyloidosis are crucial for early recognition, proper management, and to improve the patients' quality of life. A 79-year-old female initially presented with dyspnea and was diagnosed with SSS that required a pacemaker insertion. Ten days later, the patient had complained of dysphagia and difficulty swallowing. She underwent an esophagogastroduodenoscopy (EGD) to investigate further, and it revealed esophageal and duodenal ulcers, and biopsy was positive for amyloidosis. The patient was worked up for amyloidosis, including bone marrow biopsy, renal biopsy, frees light chains, and serum electrophoresis, which all confirmed the diagnosis of primary amyloidosis. Unfortunately, due to the terminal nature of her condition, the patient was discharged with comfort measures to hospice care.

A 64-year-old male with a history of transverse myelitis presented to the hospital with a decreased level of consciousness of one day's duration. CT of the head revealed intracranial hemorrhage measuring 2 x 1.2 cm in the right temporal lobe and multiple small hemorrhages in the left hemisphere, suggestive of vasculitis. Initial vasculitis workup was negative for antinuclear antibody (ANA), complement component 3 (C3), and antineutrophil cytoplasmic antibodies: P-ANCA, C-ANCA. Syphilis, hepatitis B and C, West Nile virus antibody [immunoglobulin G (IgG) and immunoglobulin M (IgM)], herpes simplex virus (HSV) polymerase chain reaction (PCR), and HIV 1 and 2 were also negative. In view of the CT scan findings suggestive of vasculitis and the vague presentation of primary central nervous system vasculitis (PCNSV), a brain biopsy was performed. It revealed angiocentric granulomatous inflammation with focal vessel disruption and associated parenchymal hemorrhage, consistent with a diagnosis of granulomatous vasculitis. The patient received levetiracetam, multiple high doses of steroids, and six cycles of cyclophosphamide for a six-month duration. After induction, he has remained in remission without any maintenance therapy until now (eight years post-presentation).

The importance of this review lies in its study of the risk of sudden cardiac death (SCD) and sudden cardiac arrest (SCA) in people living with the human immunodeficiency virus (PLWH). To the best of our knowledge, this is the first review investigating the effect of the human immunodeficiency virus (HIV) on SCD and SCA. The review's objective was to determine the risk of SCD and SCA in PLWH. To do this, the electronic databases Ovid MEDLINE, EMBASE, Cochrane Central, Scopus, and Google Scholar were systematically searched to identify eligible studies published before January 31, 2021. Reference lists of the included studies were searched for further identification of relevant studies. The search terms included: "Sudden Cardiac Death," "Sudden Cardiac Arrest," "Human Immunodeficiency virus," "HIV," "Acquired immunodeficiency syndrome," and "AIDS." Only observational studies that assessed the association between SCD and SCA in PWLH were selected. Data were extracted by two independent authors who screened titles, abstracts, and articles to meet the inclusion criterion. Quality assessment was done by using modified Downs and Black checklist. A total of seven studies were included in this review. Five studies revealed a higher incidence of SCD in PLWH, two of which focused on patients with HIV and low left ventricular ejection fraction (LVEF). The other two studies were about the association of HIV and SCA. Studies reported that PLWH had a three- to five-fold higher incidence of SCD as compared to non-HIV patients. HIV patients with low LVEF had a higher incidence of SCD than HIV patients with normal LVEF. PLWH had a higher incidence of SCA and less successful cardiopulmonary resuscitation (CPR) as compared to patients without HIV. After adjusting for various confounders in multiple studies, all the studies reported a higher incidence of SCD in PLWH. To conclude, PLWH is at an increased risk of SCD and SCA. Some risk factors for this include LVEF, viral load (VL), and the cluster of differentiation 4 (CD4) count. There is a paucity of data on the mechanisms involved, although a higher prevalence of cardiac fibrosis and interstitial fibrosis in PLWH may play a role. Because of the general suboptimal quality of the heterogeneous nature of the current evidence, further, rigorous studies are needed to determine the association of increased risk of SCD and SCA in PLWH.

We present a case of a young (43-year-old), otherwise healthy, female patient who developed drug-induced liver injury (DILI) secondary to routine use of duloxetine. Our case aims to raise awareness amongst physicians about the possibility of duloxetine-induced liver injury. We recommend monitoring liver function tests (LFTs) when initiating or adjusting the dose of duloxetine, and intermittently thereafter, to facilitate early identification and management of potential DILI.

A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also known as coronavirus disease 2019 (COVID-19), emerged in Wuhan, China, and rapidly spread across the world. Today, we present an interesting case of a patient with no prior history of pulmonary disease who was diagnosed with COVID-19, recovered after a prolonged hospital course, and was diagnosed with pulmonary fibrosis requiring oxygen therapy thereafter. The patient is currently on pirfenidone and has had a significant improvement in his functional status. His oxygen requirements have decreased, and repeat computed tomography (CT) scanning has demonstrated improvement in the extent of his pulmonary fibrosis. This case highlights the possibility of pulmonary fibrosis being a major complication among COVID-19 survivors and the importance of using pirfenidone in the management of such cases.

Objectives To explore the role of inspiratory muscle training (IMT) in improving cardiorespiratory fitness of stable heart failure with preserved ejection fraction (HFpEF) patients. Background There is a paucity of data on the role of IMT in patients with HFpEF. HFpEF is a growing problem in the developed world, especially in the aging population. Methods We conducted a systematic literature search for English studies in PubMed, EMBASE, and Cochrane Central Register of Controlled Trials. We searched databases using terms relating to or describing breathing exercise, IMT, and HFpEF. RevMan 5.4 (The Cochrane Collaboration, 2020) was used for data analysis, and two independent investigators performed literature retrieval and data extraction. Results We identified three randomized controlled trials (RCTs) and one prospective study on the role of IMT in HFpEF. We calculated the pooled mean difference of peak oxygen consumption (Peak VO2) and six-min walk distance (6MWD) between the IMT and standard care (SC) groups. Our meta-analysis showed that compared with SC, IMT could significantly improve peak VO2 with a mean difference (MD) of 2.82 ml/kg/min, 95% CI [1.90, 3.74] P < 0.00001 and improve 6MWD with MD of 83.97 meters, 95% CI [59.18, 108.76] P< 0.00001 to improve cardiorespiratory fitness at 12 weeks of IMT and improve peak VO2 with MD of 2.18 ml/kg/min, 95% CI [0.38, 3.99] P < 0.00001 at 24 weeks of therapy. Conclusion IMT should be further studied as a possible treatment option to improve cardiorespiratory fitness for patients with stable HFpEF.

Acute pericarditis is commonly diagnosed in patients who present with chest pain. Accurate diagnosis of acute pericarditis is essential because of its relative similarity to ST-elevation myocardial infarction (STEMI) in both clinical presentation and electrocardiogram (EKG) changes. Additionally, troponin elevation is occasionally seen in acute pericarditis due to myocardial involvement (myopericarditis), which makes accurate diagnosis more challenging. A 12-lead EKG remains the most useful diagnostic test in differentiating acute pericarditis from STEMI. Spodick's sign is a less recognized electrocardiographic feature of acute pericarditis and is frequently overlooked by clinicians. We present a case of a 52-year-old male who initially presented with acute onset substernal chest pain. His EKG revealed diffuse subtle ST elevation and downsloping TP segment (Spodick's sign). A coronary angiogram demonstrated normal coronaries which eliminated the possibility of coronary artery disease. In this article, we will discuss how to differentiate between acute pericarditis and myocardial infarction, with a focus on Spodick's sign, amongst other EKG findings suggestive of pericarditis.

Every year, more than 795,000 people in the United States have a stroke, the vast majority of which are ischemic. Cardiac myxoma is an unusual cause of stroke and accounts for less than 1% of ischemic strokes. We present a case of a 56-year-old male with a history of hypertension, dyslipidemia, and type 2 diabetes mellitus, who presented with altered mental status, tinnitus, double vision, and diaphoresis. Due to concern for a cerebral vascular accident, a CT scan of the brain was obtained and showed no acute intracranial process. Brain MRI revealed multiple small acute infarcts involving bilateral posterior cerebral artery distribution. Further evaluation included transthoracic echocardiography that showed a large mobile mass in the left atrium measuring 3.5 x 2 cm intermittently projecting through the mitral valve. The patient underwent successful surgical resection of the left atrial mass. The pathology report confirmed the diagnosis of atrial myxoma. This case further highlights the importance of complete evaluation of stroke, including echocardiography, as well as the importance of careful surgical resection to prevent recurrence of systemic embolization and other complications of atrial myxoma.
