RESUMEN

Background: Ventricular arrhythmias (VAs) are a common cause of death in patients with acute myocardial infarction (AMI). Studies have shown sex differences in the incidence, presentation, and outcomes of AMI. However, less is known about sex differences in patients with AMI who develop VAs. Objectives: The authors assessed sex differences in incidence and in-hospital outcomes of patients with AMI and VAs. Methods: Using the National Inpatient Sample 2016 to 2020, we conducted a retrospective analysis of patients admitted for AMI with a secondary diagnosis of VAs. Multivariable logistic regression was performed to estimate the sex-specific differences in the rates and in-hospital outcomes of VAs post-AMI. Results: We identified 1,543,140 patients admitted with AMI. Of these, (11.3%) 174,565 patients had VAs after AMI. The odds of VAs after AMI were higher among men (12.6% vs 8.8% adjusted odds ratio [AOR]: 1.72; CI: 1.67-1.78; P < 0.001). Women had significantly higher odds of in-hospital mortality (AOR: 1.32; CI: 1.21-1.42; P < 0.001), cardiogenic shock (AOR: 1.08; CI: 1.01-1.15; P < 0.022), and cardiac arrest (AOR: 1.11; CI: 1.03-1.18; P < 0.002). Women were less likely to receive an implantable cardioverter-defibrillator (ICD) (AOR: 0.57; CI: 0.47-0.68; P < 0.001) or undergo catheter ablation (AOR: 0.51; CI: 0.27-0.98; P < 0.001) during the index admission. Conclusions: We found important sex differences in the incidence and outcomes of VAs among patients with AMI. Women had lower odds of VAs but worse hospital outcomes overall. In addition, women were less likely to receive ICD. Further studies to address these sex disparities are needed.

RESUMEN

Cabozantinib, a multi-kinase receptor inhibitor, is utilized in the treatment of advanced malignancies such as metastatic renal cancers. While rare, cabozantinib-induced cardiotoxicity has emerged as a recognized adverse effect with potentially reversible outcomes. We report the case of a 55-year-old male who developed fatal cardiomyopathy 4 months after initiating cabozantinib therapy. Despite its rarity, cardiomyopathy after initiation of cabozantinib can be lethal if not diagnosed early. This case underscores a significant gap in the surveillance of patients treated with newer agents like cabozantinib. Larger observational studies are needed to assess the prevalence and impact of cardiomyopathy after initiation of cabozantinib therapy, and to determine the cost-effectiveness of early surveillance protocols.

RESUMEN

Myocarditis is a potentially fatal medical condition with varied etiologies. Peripartum cardiomyopathy (PPCM) refers to systolic dysfunction occurring toward the end of pregnancy or in the months following delivery; it is a diagnosis of exclusion. We present a patient with chest pain, bipedal edema, markedly elevated troponins, electrocardiogram (EKG) findings that were concerning for myocardial infarction, and a significantly reduced left ventricular ejection fraction (LVEF) on the echocardiogram. The patient's presentation in the postpartum period closely resembled peripartum cardiomyopathy and presented a peculiar diagnostic challenge to our team. The right diagnosis was possible with cardiac magnetic resonance imaging, which revealed late gadolinium enhancement. Additionally, the patient had positive Coxsackie B5 and Epstein Bar virus serologies. While the clinical course of the disease is often benign, it could rapidly deteriorate, so early recognition and diagnosis are important to ensure patients receive adequate therapeutic support.

RESUMEN

BACKGROUND Angioedema is non-pitting edema that occurs in the deep layers of the skin and subcutaneous tissue due to vascular leakage of plasma resulting from 1 of 2 major pathophysiological processes: mast cell-mediated angioedema and bradykinin-mediated angioedema. While it is a well-recognized adverse reaction of angiotensin-converting enzyme inhibitors, the association of angioedema with angiotensin receptor blockers is relatively less studied. Direct local trauma, although rarely, has been suggested to induce angioedema under certain conditions. We present a unique case of direct, local, trauma-related angioedema in a patient on an angiotensin receptor blocker. CASE REPORT The patient, an 83-year-old woman on telmisartan for hypertension, hit her neck against the edge of a chair during a fall. Shortly thereafter, she developed progressive airway compromise due to airway angioedema, as noted on direct laryngoscopy. A contrast CT scan of the neck also noted edema of the periglottic and supraglottic regions. She required intravenous corticosteroid administration and intubation in the emergency room and was successfully extubated 3 days after admission. She had no prior history of angioedema or allergy. We hypothesize that increased levels of circulatory bradykinin in the setting of telmisartan, combined with a local release of bradykinin from trauma, was the main pathophysiologic cause of the angioedema. CONCLUSIONS This case report highlights the rare and often forgotten adverse reaction of angioedema with use of angiotensin receptor blockers and confirms the finding of local trauma as a possible trigger.

RESUMEN

Aim: Coronary heart disease (CHD) increases the risk of adverse outcomes from invasive pneumococcal disease. Methods: Using the 2020 and 2021 data from the national health interview survey, we identified adults with CHD. Chi-square analysis and logistic regression were used to examine factors that influence vaccination status. Results: There were 2675 participants aged 41 and above with CHD. Participants were predominantly white people (82.5%) and males (60.1%). The odds of receiving the pneumococcal vaccine increased with stepwise increase in comorbidities from 1 to 2 and from 2 to 3. Among individuals with ≥2 comorbidities, black people were less likely to be vaccinated compared with white people. Conclusion: Pneumococcal vaccine uptake among adults with CHD is determined by cumulative comorbidities and ethnicity.

RESUMEN

Cefepime-induced non-convulsive status epilepticus (NCSE) is a recognized adverse event of cefepime. Risk factors for this adverse event include older age, underlying renal dysfunction, previous brain injury, diabetes, and severe infection. We present a case of a 79-year-old woman with no prior seizure history, who was admitted for Pseudomonas aeruginosa surgical wound infection for which she was on cefepime. She developed acute encephalopathy with associated, occasional, right-sided myoclonic facial twitches 11 days into her admission. Electroencephalogram (EEG) confirmed NCSE as evident by epileptiform activity described as generalized periodic discharges with predominantly triphasic morphology. Cefepime was substituted with piperacillin-tazobactam> 24 hours after symptom onset. NCSE completely resolved two days after the discontinuation of cefepime. This case highlights the fact that NCSE can occur even when precautions such as renal dosing of cefepime are observed. Clinicians need to have a high index of suspicion for the condition when taking care of at-risk patients on cefepime, as delayed diagnosis correlates with potentially fatal outcomes.

RESUMEN

Hemophagocytic lymphohistiocytosis (HLH) is a rare and often missed presentation in the hospital setting. It is a hyperinflammatory syndrome of immune activation and dysregulation characterized by fever, cytopenias, elevated serum ferritin levels, and hepatosplenomegaly. It has a multifactorial etiology occurring primarily secondary to infection, malignancy, immune checkpoint inhibitors, or autoimmune disease. HLH that occurs in autoimmune diseases such as adult-onset Still's disease and systemic lupus erythematosus is referred to as macrophage activation syndrome. However, it may rarely be a primary disorder from a genetic defect. The pathophysiology of HLH is poorly understood and often results in multiorgan dysfunction. We present an older adult male patient with several hospital stays due to his symptoms, who presented with lethargy, low-grade fever, cough, dyspnea, and recurrent pleural effusions. He had bicytopenia, elevated ferritin, and hypertriglyceridemia. The diagnosis of HLH may be delayed, especially in older adult patients with an insidious course, and requires a high index of suspicion.

RESUMEN

The incidence of infective endocarditis (IE) has been on the rise since it was first reported a century ago, and the associated mortality remains unchanged despite advances in medical and surgical management. To diagnose IE, the modified Duke criteria are used, which rely on isolating the causative organism. However, this can be challenging if the micro-organism is considered a contaminant. Staphylococcus lugdunensis (SL) is one such organism. In this case, an elderly female presented with intermittent chest pain, palpitation, and diaphoresis, for which she underwent left heart catheterization. Her hospital course was complicated by persistent fever and night sweats, leading to blood cultures isolating methicillin sensitivity. It was initially reported as a contaminant. However, an extensive workup was unremarkable, and a transthoracic echocardiogram was done, which revealed tricuspid vegetations with moderate regurgitation. The patient was treated with cefazolin, repeat cardiac imaging at the end of treatment revealed no vegetation, and the patient remained asymptomatic. Despite being associated with fulminant IE with higher mortality than Staphylococcus aureus (S. aureus), which requires surgical management in most cases, SL is still often reported as a contaminant. Isolation of SL should warrant further investigation beyond mere contaminants, and prompt treatment should be initiated in the appropriate clinical scenario to avoid poor outcomes.
