Left atrial appendage occlusion: an alternative to anticoagulation for stroke prevention in kidney disease

Anticoagulation to reduce thromboembolic stroke risk due to nonvalvular atrial fibrillation in ESRD is associated with increased bleeding. Existing debate in ESRD centers around the pros and cons of anticoagulation. We propose percutaneous left atrial appendage occlusion as a third alternative to balance thrombosis and bleeding risks in this high risk population.

A United States national analysis of basic demographics and commodities in sudden cardiac arrest

Background Cardiac arrest is a condition associated with high mortality rate and can cause significant social-economical burden in United States. Our study aim is to analyze the basic demographic of patients admitted for cardiac arrest and the incidence of complications following cardiac arrest. Methods Using the National Inpatient Sample from 2016–2018, we identified all the hospital admissions with a primary diagnosis code at discharge for cardiac arrest during the study period. We identified the basic characteristics including age, gender, race and admitting hospital status. The set primary outcome was inpatient mortality, length of stay (LOS) and total costs of admission. The secondary outcomes were the incidence of acute kidney injury, acute blood loss anemia, acute embolism and thrombosis of deep veins of lower extremity (DVT), pulmonary embolism, non-traumatic intracranial hemorrhage, and thromboembolic stroke. Multivariable logistic regression model analysis was performed to address potential confounders. The Charlson Comorbidity Index (CCI) was used to adjust for the severity of each patient's co-morbidities. Results A total of 44,655 patients was admitted for cardiac arrest during the study period. Mean age was 64 years; 56% were men; 63% were white, 20.7% were black, 9.2% were latino, 2.8% were Asian or pacific Islander. The total in-hospital mortality was 73.5%. The average length of stay was 4.2 days and the average total costs of admission was 83,516 dollars. Among the seven demographic characteristics: age, gender, race, hospital size, hospital region, hospital teaching status, insurance type; only hospital teaching status and hospital size were found to significantly impact the mortality. Acute kidney injury was the most common complication in post-cardiac arrest patient (42%), followed by acute blood loss anemia (3.6%), pulmonary embolism (2.3%) and DVT (2.1%). Thromboembolic stroke (0.2%) and non-traumatic intracranial hemorrhage (0.1%) are less common. During subgroup analysis, acute kidney injury was also found out to be a predictive factor of increased mortality (OR 1.64, p<0.001). Conclusion Cardiac arrest remains one of the conditions with highest mortality rate. In our study, age, gender or race dit not impact on the outcome of cardiac arrest. Among all the complications from cardiac arrest, acute kidney injury was the most common one and was associated with higher mortality rate. FUNDunding Acknowledgement Type of funding sources: None.

CORRELATION BETWEEN C- REACTIVE PROTEIN AND LIPID ABNORMALITIES IN SUBJECTS WITH ISCHEMIC STROKE

Cerebrovascular accident, which has considerable mortality and morbidity,deservesattention towards its prevention. The first lines of defense in stroke prevention are detecting and adequately treating manageable risk factors, C-Reactive protein, an acute phase reactant is an indicator ofunderlying systemic inflammation and a novel marker for atherothrombotic disease. Present study is an attempt to study the levels of C-Reactive protein in acute thromboembolic stroke and to correlate between serum C Reactive protein levels and lipid profile in acute ischemic stroke.

Postoperative atrial fibrillation in paraesophageal hernia repair: can it be prevented?

Acute ischemic thromboembolic stroke is one of the most feared complications of atrial fibrillation (AF), and the risk increases with higher CHA2DS2-VASc scores. Postoperative atrial fibrillation (POAF) is common after noncardiac surgery, particularly after thoracic surgery, and can result in significant morbidity and mortality. We report the case of an 85-year-old female with a history of untreated hypertension (HTN) and no prior history of AF, who presented 5 days after an elective repair of a paraesophageal hernia with recurrence of a large type III paraesophageal hiatal hernia, AF, and subsequent acute thromboembolic ischemic stroke. Patient’s AF resolved shortly after treatment with calcium channel blocker. The risk of stroke is high in patients who develop AF and a period of 48 h after onset of AF is usually considered safe as the risk of stroke is low in this time period. However, this may not be the case during the perioperative period and preventive measures such as preoperative calcium channel blocker could be considered. Our case highlights that acute ischemic thromboembolic stroke might develop earlier tha 48 h after onset of POAF in patients undergoing paraesophageal hernia repair. Initiation of a calcium channel blocker should be considered during preoperative evaluation for patients undergoing paraesophageal hernia repairs, especially in those with untreated HTN.
