Dapagliflozin in Heart Failure: A Comprehensive Meta-analysis on Functional Capacity, Symptoms, and Safety Outcomes.

OBJECTIVE: To evaluate the comparative effects of dapagliflozin versus placebo in patients with heart failure (HF), focusing on functional capacity, symptoms, and safety outcomes. BACKGROUND: Despite advancements in heart failure (HF) therapy, HF is still a significant cause of recurrent hospitalization and death worldwide. Dapagliflozin has demonstrated potential in lowering hospitalizations and mortality associated with heart failure; however, its impact on functional capacity, particularly the 6-min walk distance (6MWD), and the comprehensive assessment of safety outcomes in diverse HF populations, including those with preserved or reduced ejection fraction (HFpEF and HFrEF, respectively), requires further investigation. METHODS: PubMed, Web of Science, Cochrane Library, and Scopus databases were comprehensively searched to identify randomized controlled trials (RCTs) investigating the efficacy of dapagliflozin in comparison with control interventions for heart failure. The primary outcome was a change in the 6MWD, KCCQ score, and safety measures included hospitalization, all-cause mortality, and adverse events. RESULTS: In our meta-analysis of ten studies involving 12,695 patients with heart failure, dapagliflozin showed significantly improved Kansas City Cardiomyopathy Questionnaire (KCCQ) scores [risk ratio (RR) of 2.75, 95% confidence interval (CI) (1.95-3.569), p < 0.00001] and no significant differences in 6-min walk distance [6MWD; RR of 3.59, 95% CI (- 1.44 to 8.63), p = 0.16]. Dapagliflozin demonstrated a notable reduction in hospitalization for heart failure [RR of 0.76, 95% CI (0.68-0.84), p < 0.00001], significant overall reduction on the effect of any cause mortality [RR of 0.90, 95% CI (0.83-0.99), p = 0.03). There was, however, no significant effect on adverse events [RR of 0.96, 95% CI (0.98-1.03), p = 0.39). CONCLUSIONS: Our meta-analysis of ten trials concluded that dapagliflozin significantly improved KCCQ scores in both HFrEF and HFpEF. The improvement in 6MWD was not statistically significant but trended toward dapagliflozin. Dapagliflozin also showed a mortality benefit in patients with reduced ejection fraction; however, in patients with preserved ejection fraction, the result was not statistically significant. There was also a statistically significant reduction in heart failure hospitalizations across all classes.

A fatal case of cabozantinib-induced cardiomyopathy.

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.

Cardioembolic Stroke Three Days Post-Video-Assisted Thoracoscopic AtriClip in a Patient With Paroxysmal Atrial Fibrillation.

Atrial fibrillation is a global epidemic due to aging and chronic diseases. Treatment options are expanding to prevent thromboembolism in anticoagulant-ineligible patients. The left atrial appendage, implicated in 90% of embolic strokes, is increasingly managed with occlusion devices like the AtriClip. A 62-year-old woman with prior stroke, severe gastrointestinal bleeding on anticoagulation, and paroxysmal atrial fibrillation experienced sudden left-sided weakness and altered mental status three days post-AtriClip procedure. Brain MRI revealed acute infarcts in the right cerebellum and scattered punctate infarcts in both cerebral hemispheres. No further invasive investigations or interventions were recommended, as they would not influence management. Left-sided weakness improved, and the patient was discharged to a subacute rehabilitation center. Despite the AtriClip's ability to lower stroke incidence by occluding the left atrial appendage, there remains a residual risk of cerebrovascular events that can significantly impact morbidity and mortality. This case underscores persistent risks despite complete appendage closure, emphasizing the need for broader studies on post-AtriClip stroke risk.

Thyroid Troubles: A Case of Hypothyroidism-Associated Recurrent Massive Pleural Effusion.

Pleural effusions can be secondary to several different etiologies. Sometimes, they can be related to hypothyroidism. We present a case of massive pleural effusion resulting from hypothyroidism. A 75-year-old male with a history of liver cirrhosis, hypothyroidism, and medication non-adherence presented to the emergency department (ED) with shortness of breath and altered mental status. Physical exam and chest imaging were consistent with right-sided pleural effusion. Effusion was exudative. Multiple recurrences complicated the hospitalization despite thoracentesis and pleurodesis. Labs revealed hypothyroidism, and finally, the patient was started on hormone replacement, resulting in the resolution of the effusion. Pleural effusion is a rare manifestation of hypothyroidism, thought to be mediated by vascular endothelial factors. Pleural fluid analysis shows both exudative and transudative patterns. Hormonal replacement is the mainstay of treatment. Clinicians need to be aware of the rare etiologies of pleural effusion. Depending on the patient's presentation, due work-up should be done to ensure a timely diagnosis and management.

The Masquerading Myocarditis: A Case of Late Recurrence of Acute Myocarditis Presenting as "Peripartum Cardiomyopathy".

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.

A Case of Trauma-Related Angioedema of the Airway in a Patient on an Angiotensin Receptor Blocker.

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.

The impact of comorbidities and sociodemographic predictors on pneumococcal vaccination coverage in adults with coronary heart disease.

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.

Delayed Diagnosis of an Invisible Seizure: Cefepime-Induced Non-convulsive Status Epilepticus.

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.

The Thyroid Forecast: A Case of a Thyroid Storm Diagnosed Under Unforeseen Circumstances.

Hyperthyroidism and thyrotoxicosis are common conditions in clinical practice. Untreated, they are associated with several co-morbidities. One of these conditions, and arguably the most lethal, is the thyroid storm. Our case presentation is one of a young female who had previously been diagnosed with thyroid illness but was lost to follow-up, subsequently given a clean bill of health, and emerged with what would eventually be diagnosed as a thyroid storm. While the thyroid storm may pose some diagnostic challenges, it has come a long way in securing diagnostic tools. What remains is a tool for physicians and patients to stratify patients by their risk of developing a storm in the outpatient setting.

The Deadly Contaminant: A Case of Staphylococcus lugdunensis Endocarditis.

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.
