Variation in heart rate range by 24‐h Holter monitoring predicts heart failure in patients with atrial fibrillation

Aims The analysis of heart rate fluctuations, such as HR fluctuation or HR turbulence, has been published as a predictor of cardiovascular events during sinus rhythm; however, those relationships during atrial fibrillation remain variable, and these measurements are not widely used in AF patients. With a simple index that focuses on heart and heart failure in patients with permanent AF, we wanted to investigate the connection. Methods and findings We enrolled 198 patients with permanent AF and assessed the HR range, which is defined as the highest HR on 24u2010h Holter electrocardiogram recordings. Due to exacerbations of one's HF status, hospitalizations for HF or urgent hospital visits were deemed as hospitalizations for HF or urgent hospital visits. HF events occurred in 37 patients during the observation period of 1825 days. The larger HRR group had more frequent HF events than the smaller HRR group, according to a log-u2010rank survey. P = 0. 002] For the larger HRR group, the adjusted Cox proportional hazards model utilized the substantially different variables from the initial univariate analysis and medications associated with HF was higher than the smaller HRR group's smaller HRR group [Model 1, adjusted hazard ratio] 1. 21, 95%, P = 0. 002; Model 2, adjusted hazard ratio = 3. 12, 95%], P = 0. 002]. HF events were also associated with permanent AF in patients with permanent AF.

Atrial fibrillation is an independent risk factor for heart failure hospitalization in heart failure with preserved ejection fraction

Atrial fibrillation in heart failure is a common comorbid condition with preserved ejection percentages. The effect of AF on heart failure exacerbation in HFpEF has not been well defined. After hospitalization for decompensated HF, this review explored how AF modifies the clinical course of HFpEF patients. Methods and findings We stratified HFpEF participants by AF diagnosis and longitudinal examination to determine risk for HF hospitalization after index hospitalization for decompensated HF. Subjects with AF were older, more often male, and had a larger left atrial diameter than those without AF. Following multivariable competitive risk regression with propensity score weighting, subjects with AF had a higher risk of HF hospitalization than those without AF; this association remained significant following multivariable competing risk regression with propensity score weighting. Conclusions Atrial fibrillation is a risk factor for HF rehospitalization in HFpEF, according to the authors.

Gastrointestinal bleeding during direct oral anticoagulants therapy in patients with nonvalvular atrial fibrillation and risk of polypharmacy

This research was conducted to explore the connection between concomitant drugs and potential pharmacokinetic interactions, a number of concomitant medications, bleeding and embolism in patients with nonvalvular atrial fibrillation on DOACs. The patients were 1,010 patients treated DOACs from a single u2010center at Teikyo University Hospital between April 2011 and June 2018. There was a significant risk of gastrointestinal bleeding when taking ten or more oral medications concurrently. The only significant risk of gastrointestinal bleeding was nonsteroidal anti-u2010inflammatory drugs. When using DOACs with patients taking more than 10 medications and/or NSAIDs, physicians should be aware of gastrointestinal bleeding.

Prediction of atrial fibrillation in patients with hypertension: A comprehensive comparison of office and ambulatory blood pressure measurements

However, the relationship between diurnal changes in BP and AF has not sufficiently investigated. This paper intends to cross-u2010sectionally investigate the link between AF and ambulatory BP parameters, particularly reverse dippers to the others, and then investigate how BP patterns are related to the risk of experiencing new-onset AF. The multivariate logistic regression study revealed that reverse dippers were significantly more likely to have AF compared to cross dippers. AF patients were excluded from baseline AF during the mean follow-up of 4. 6 u00b1 3. 0 years seven patients were diagnosed with AF after excluding patients with baseline AF in the mean follow-up of 3. 6 u00b1. Longitudinously, the multivariate Cox regression study revealed that 24 u2010h systolic BP, nighttime systolic BP, and the presentation of reverse dipping were independently linked to new onset AF, as well as nighttime systolic BP. Although ambulatory BP results were more accurate predictors of AF incidence, careful monitoring is required for reverse dippers, who are at a high risk of developing AF.

Surgical correction of left auricular aneurysm herniation through a pericardial defect in a dog with atrial fibrillation and mitral valve disease

When clinical signs are unmanageable and reduce the risk of thromboemboli, surgical intervention is recommended. A 15-u2010year-u2010, 4. 1 kg, U2010kg spayed female Shih Tzu dog brought to the hospital with a 6-month history of failure and syncope episodes. The dog had been diagnosed with degenerative mitral valve disease 9 years ago. Following surgery, Atrial fibrillation reverted to normal sinus rhythm, but recovery was uneventful. The Syncope episodes were never resolved.
